LETTERS FROM CHARLES SPRAGUE SARGENT TO 
REGINALD SOMERS COCKS, 1908-1926 * 


Edited by JosEpH Ewan ! 


WHEN CHARLES SPRAGUE SARGENT DIED IN 1927, after serving 54 years 
as Director of the Arnold Arboretum, he left a varied and significant legacy 
of botanical accomplishment. The Arnold Arboretum which he established 
is a monument to his vision, energy, and ability. His published works are 
a record of his interest in and knowledge of woody plants. After comple- 
tion of his magnum opus, the Silva of North America (1891-1900), Sar- 
gent wrote the Manual of the Trees of North America which was, in fact, 
a condensed version of the Silva, available to many more interested people 
than had access to the original work of 14 folio volumes. 

e production of a manual with its necessarily concise statements of 
characterization, distribution, uses, and so forth, entails an enormous effort 
and a refinement of style not easy to achieve. To obtain the greatest pos-

intensively. Eds.

sible precision in statements of range and other details, Sargent encouraged 
correspondents in various parts of the country to provide specimens and all 
available information about the trees in their particular localities. From 
the time of publication of the first edition of the Manual Sargent worked 
for approximately fifteen years toward the completion of the second edi- 
tion. Among the many correspondents who contributed to the effort, 
Sargent especially mentioned, in the preface to the second edition, Alice 
Eastwood who collected in Alaska and New Mexico, and Professor Cocks 
who explored the forests of Louisiana. 

Sargent apparently first met Professor Cocks early in 1908. Unfor- 
tunately we do not know the content of the first letter Sargent received, 
for incredibly Cocks’s incoming letters were not kept together, and only 
occasional letters or paragraphs from them may be found pocketed with 
herbarium specimens in the Arnold Arboretum. Professor Sargent quickly 
detected the aptitudes and values of his newfound correspondent, for his 
302 letters to Cocks, reproduced here, were written sometimes daily, once 
two in a day, and with few long intervals, until twenty days before Profes- 
sor Cocks’s death on November 21, 1926. Sargent himself died four months 
later, on March 22, 1927. 

Reginald Wodehouse Somers Cocks was born August 31, 1863, at Pap- 
worth, Worcestershire, England. He attended Trinity College, Cambridge, 
where he took the M. A. degree, in 1889, with first honors in classics. His 
interest in Latin persisted through his lifetime. There is a letter from Ben- 
jamin Lincoln Robinson, Curator of the Gray Herbarium, dated February 
13, 1917, thanking Professor Cocks for his estimate of a paper which con- 
tained some Latin with which he disagreed. In this Dr. Robinson wrote, 
“T have no doubt that you are entirely right that my Latin contains 
various slips. 

Although there are Cocks specimens in the Tulane Herbarium labelled 
“Feliciana, March, 1892,” and “Feliciana, April, 1895,” as well as some 
collections made in 1897, Professor Cocks’s active botanizing began in 
March, 1898, and continued through that season. On May 27, 1898, he 
presented his first paper at the meeting of the Louisiana Society of Natural- 
ists on Selaginella apus |S. apoda| growing in profusion at Mandeville, 
Louisiana. The Society had been organized July 3, 1897, and ape iba 
May 1, 1899, with Professor J. H. Dillard as its first president. “Mr 
S. 0c ks, M. A.”’ is listed as a member of the executive committee for sis 
year 1898-99, at the time he was an instructor at Boys’ High School in 
New Orleans. Cocks and Professor George E. Beyer of Tulane completed 
a series of “excellent lectures on botany and zoology” given under the 
auspices of New Orleans Free Lecture System, according to a report in the 
Gulf Fauna and Flora Bulletin for June, 1899. June, 1899, included trips 
as far afield as Lake Charles prairies and Selma, Alabama, the home of 
Mrs. Cocks, and August, excursions to Alexandria and vicinity. From 1900 
on, year after year, regular field trips, with special attention given to the 

y plants, were made into all sections of the state. Cocks, like another 
eles, Philip Henry Gosse, first arrived in Canada from England

but evidently did not stay in the north. A few herbarium labels suggest 
that he may have arrived in New Orleans as early as 1890 but this evidence 
is not wholly trustworthy. On other occasions specimens from opposite 
sides of the state carry the same month; yet it is highly unlikely that in 
those days he could have moved about so rapidly. Cocks generally recorded 
only the month and the year on his labels, and did not number his collec- 
tions. Professor Sargent subsequently numbered some sheets for easy ref- 
erence. For example, a Carya collection from Clear Lake, Natchitoches 
Parish, May, 1909, later became number 1765; another from Bayou La- 
combe, St. Tammany Parish, across the state, also May, 1909, is number 
1766. 

After a year as Professor of Botany at Louisiana State University, 
1906-07, Professor Cocks moved to Tulane to occupy the newly created 
Ida A. Richardson Chair of Botany. Mrs. Richardson took an active 
interest both in living plants and in books about them (our Tulane set of 
Sargent’s Silva was her gift). It is notable that, on several occasions, 
Sargent mentions sending seeds or plants of foreign introductions, recently 
grown at the Arnold Arboretum, as possible additions to New Orleans 
gardens. This was in the spirit of Ida Richardson who is credited, and 
with good evidence, for the introduction of Cocculus laurifolius, Siphonan- 
thus indicus, and other exotics into local gardens and patios. Through the 
years Professor Cocks supported the activities of the New Orleans Garden 
Society, and a volume of his collected papers was presented to the Society 
by one of its members, Mrs. J. Leo Burthe. Over and beyond his lecturing 
to garden clubs and his teaching of botany classes (his lecture notes have 
survived) was his enthusiasm for searching out new plant records for 
Louisiana. Here Sargent found a devoted colleague. It is abundantly 
clear from his letters that Professor Cocks conscientiously ran the errands 
Sargent put to him. And the errands kept coming, in extremis with Sar- 
gent’s advancing concern that the revised Manual might not be finished 
before his life was ended. The first edition of the Manual had appeared 
in 1905 and immediately corrections and additions began to accumulate 
in the desk copy. When another collector provided a range extension in 
Louisiana, Sargent wrote Cocks to verify it. Mattoon found Pinus car- 
ibaea [P. elliottii var. elliottii]! in the Tangipahoa region, and Sargent 
wrote for Cocks to hunt for it in other parts of the state where it might 
have been overlooked. From these collecting trips Sargent recognized five 
new species or varieties of hickory, a new hybrid oak (Quercus « cock- 
sit) from near Alexandria, a hawthorn (Crataegus cocksii) from near 
Winnfield, and a linden (Tilia cocksii) from near Lake Charles. Sargent 
accompanied Cocks on several field trips over the state, testing revised 
keys in the field, collecting specimens in flower and fruit, and following up 
old records made by nineteenth century botanists. The two men marked 
trees to return to for successive vouchers, especially the oaks where the 
yields of fruit vary from year to year. 

The zeal of the plant collector and the comradeship of the botanists por- 
trayed in the letters which follow may be gleaned from a letter by Ernest 


‘ 


6 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Jesse Palmer (often mentioned in Sargent’s letters) to Professor Cocks 
dated March 5th, 1926, the year of his death. Palmer wrote ‘With refer- 
ence to the Yucca louisianica at Ruston L[ouisian|a, of which I sent you 
a small snap, I regret to say that I have no duplicate material. When I 
saw it and made the photographs I was travelling with Dr. Small in his 
truck (the famous ‘weed wagon’). I took some specimens, but as you 
know, flowers of these plants are very hard to dry, and as we didn’t have 
much chance for changing dryers on the trip practically all of the material 
was spoiled, and I only managed to save enough for one meager specimen 
for our herbarium. 

“T was sorry to learn that you have been laid up. Have had a bad cold 
myself the past month, but have managed to keep going. | Palmer lived 
thirty-six years after this bout.] Professor Sargent, I am glad to report, 
has been in much better health and has been at the Ashoxctum almost 
every day during the winter. He is truly a remarkable man.’ 


ACKNOWLEDGMENTS 


My thanks first, to Professor William T. Penfound, of the University 
of Oklahoma, formerly at Tulane, for insuring the preservation of the 
Sargent letters during his years at the University. To Charlotte Ponder 
for her careful typing of the manuscript, and to Nesta Dunn Ewan for her 
critical editorial eye and her assistance with the indices, I express my very 
real appreciation. 


April 7, 1908. 
My Cear Professor Cocks: 

I want to tell you what a very pleasant day I had in Shreveport, thanks 
to your letter of introduction. I saw the Mesquite and the Gleditsia, 
although they were not yet in flower. The Gleditsia is certainly very close 
to Gleditsia aquatica. There is only one plant of it. I should say now, 
without having seen the flower, that it would be best to consider it a 
variety of that species, although the longer pods and greater number of 
seeds is remarkable. Possibly other individuals will be foun 

I noticed in Jackson Square, New Orleans, three or four small trees of 
what I thought to be an eastern Asiatic Acanthopanax which I did not 
recognize. Do you know anything about these trees, and can you dry some 
specimens of the foliage for me? Is it possible to find out where these 
plants came from? I am afraid they are not old enough yet to flower. 

This short visit to Louisiana impressed me more than ever with the 
beauty and interest of the state and I feel very keen to get back and to 
visit those parts of the state which I have not seen, namely the region east 
of Baton Rouge and west of Vicksburg. 

I hope another year we may be able to manage a trip together. It is a 
great pleasure to me to make your acquaintance and I hope that I shall 
hear from you again.

April 21, 1909. 
You remember that you sent me a specimen of a Tilia from Shreveport 
which I told you was probably Tilia americana. I am satisfied now that it 
is not Tilia americana, and that it is perhaps Tilia leptophylla which you 
will find mentioned in Small’s Flora. I very much want to get flowers of 
this Louisiana Tilia and to know something of its distribution in the state. 
The same plant appears to grow on the Red River in Arkansas. Can’t you 
get your correspondents to look out for this tree in Louisiana and especially 
to obtain good flowering specimens as these have not, so far as I know, 
been collected? 
I wish we were in the woods together now. 


3 
December 8, 1909. 
I now expect to be in Boston at the end of the month and, if you are 
coming here, I hope you will stay at my house. You can reach Boston very 
easily from there and also the Arboretum. It would be a great pleasure 
to me to see you again and to have you as my guest. There are many sub- 
jects we ought to discuss about southern botanical explorations.

January 17, 1910. 

I am very glad to hear that you got home safely and are enjoying warm 

weather again. Here we have had bitterly cold weather and a good deal 

more snow, and I am longing for Louisiana or some other country of a 

oa climate than New England. Many thanks for your package of 
plan 

pee is certainly Aesculus austrind. 


The Bumelia from Slidell without fruit is B. lanuginosa. The others 
seem to be correctly named. 
It was a great pleasure having you in Brookline.

April 8, 1910. 
I write to say that I got home safely and to thank you again for all your 
kindness to me during my visit in Louisiana. I never had a better week 
or saw finer or more interesting trees, and we certainly must have another 
trip together before long. I understand that you will obtain flowers of 
Aesculus Pavia for us, flowers of Crataegus and Persimmon from Lucknow, 
and fruit of Salix from Shreveport and Bayou Sara. Any other specimens 

will be most acceptable. 
I am curious to hear about the Willow at New Orleans. The Shreveport 
Willow grows at Fulton, Arkansas, and also at Allenton which is about 


8 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


thirty miles from St. Louis and apparently is a common and widely dis- 
tributed tree. I cannot believe that it is only Salix nigra. A little more 
study of Louisiana Willows is going to lead to all sorts of surprises. The 
trouble is we have all been taking too much for granted. I find that we 
have n’t here a copy of Dodson’s Bulletin on Northern Louisiana Shrubs. 
If you can get a copy of it for the library here, I shall be much obliged. 

I hope you got home comfortably and found everything all right at 
home. The mud at Fulton was about three feet deep. I never saw such 
roads before, but it did not rain and I was fortunate in finding in full 
flower the Oak I was looking for. I had a good day at Allenton and found 
there at least five species of Prunus, all of which had been passing for 
Prunus americana, and so it goes. 


6 
April 21, 1910. 

Glad to get your letter of the 18th. I am much interested in what you 
say about Hamamelis. Have you perhaps found a third species? The Mis- 
souri plant flowers in February and March in a region which must be 
several weeks earlier than Louisiana. The habit you describe, too, is dif- 
ferent. The Missouri plant grows always in the sandy and rocky borders 
of small streams and spreads into large thickets by underground roots. I 
should judge from what you say that your plant has not this habit. 

How about the Willows at New Orleans and also the Diospyros at New 
Orleans? Did you get the fruit of the Willow at Bayou Sara? I am 
anxious to hear fuller accounts of your trips since we separated. 

It is a very early spring here indeed. 


7 

May 16, 1910. 
I have yours of the 10th and will write you about the plants when they 
arrive. Pearl Island must be directly at the mouth of Pearl River. I think 
I have seen the name on old maps. If you have access to a copy of Bar- 
tram’s Travels, notice what he says about it. I suppose you know that he 
went as far as Baton Rouge. I cannot think that there is any trouble in 
finding this island, and I have no doubt the Plum-tree is still growing on it. 
I very much hope that you intend to pass August in this part of the 

world. We will try to give you as good a time as possible. 


8 
June 7, 1910. 
Very sorry to hear that you had such a bad time on Campbell Island,? 
but the fact that you found no Plum tree there may save us a lot of trouble 
in the future. I have been very busy lately and have only just now been 
able to look at your plants. We shall send you soon the names of several 
of them.

With regard to the Hamamelis, your plant from Richlands appears 
identical with the spring-flowering species from west of the Missouri River. 
Probably it is the same thing which grows at Alexandria, Louisiana, I do 
not feel so sure of the Covington plant. I collected it there myself and 
have always felt doubtful about it. We must try and get flowers or find 
out just when it blooms. 

I find that Mohr in 1885 collected your Lindera at Opelousas. We have 
what looks like the same thing, too, from Georgia, and in Missouri there 
are plants with less pubescence than yours which seems to connect it with 
the northern form, J am inclined to think now that your plant will have 
to be considered a variety. Your fruiting specimen which we have was 
collected June 15th and of course — the fruit was ripe. You ought to 
try and get mature fruiting specim 

The Richlands Diospyros panes looks very different both in the 
character of its tomentum and in the shape of the leaves. I presume that 
the trees in the New Orleans swamps are the same thing, although the 
leaves are certainly less cordate and more like those of more northern forms 
but the tomentum seems identical. The thing now is to get the fruit and 
the mature leaves. I hope you will be able to manage this. We ought, too, 
to have mature leaves of the Willows which you collected, and also mature 
leaves and fruit of the different plums. This I am afraid will prove more 
difficult, but perhaps you will be able to manage some of them. Any hope 
from our friends at Shreveport in this matter? 

The plum business is very difficult owing to the difficulty of getting 
material and finding good characters by which to distinguish the different 
forms. I hope you are arranging to be in this part of the world this 
summer, 


June 13, 1910. 


Your Vacciniums are, — 


72, V. Elliottit, 
79, V. Elliottit?

89, V. stamineum,

This I believe disposes of your unnamed plants except the Willows and 
Persimmons, and it will take some time to work these up

October 12, 1910. 
Many thanks for the three lots of plums which arrived today in capital 
condition. I have to thank you, too, for the Persimmon fruit which came 
sometime ago. So far as the shape of the fruit of the two kinds is con- 


10 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


cerned I see nothing very remarkable about it for the fruit of the common 
Persimmon shows as much or more difference in variation. The pubescence 
on the Persimmon, too, seems to be a very variable character. The fact 
that one form grows in water continuously, or nearly continuously during 
the year, and the other only on dry land is remarkable and we ought to 
find some other characters beyond the shape of the fruit to separate these. 
I think there is a difference perhaps in the time of blooming and possibly 
in the size of the flowers. 

Is there any thing new in the Salix situation and have you foliage speci- 
mens for us? 

I hope you are well and enjoying life, and have no University troubles 
on your hands. 


11 
December 14, 1910. 

I am much obliged for your letter of November 28th (I am ashamed to 
see how long it has remained unanswered) and for the package of plants. 

3£8, Pearl River, is certainly Asimina parviflora. I do not know any 
A. pubescens. 

#9, C vii. of Shreveport, is Crataegus spathulata. 

#11, C iii. of Shreveport, is Crataegus arborescens. 

413, Amelanchier canadensis |var.| tomentula Sargent is the best I 
can do for this. It seems the same as the Covington tree. 

+22 and #23, ii. and iii., Shreveport, Crataegus spathulata. 

I cannot say anything about the plums yet; indeed I am more ignorant 
about them than I was a year ago, still we will do something with them 
sooner or later. As you know, it is an extremely difficult genus to collect, 
because they flower when there is nothing else to collect and the fruit 
ripens early when it is hot and botanizing is disagreeable. 

I have never seen flowers or fruit of Cephalotaxus japonica, which seems 
to be an abnormal garden form with erect branches of some other species. 
If you have specimens of the flowers and fruit, we shall be very glad to get 
them. 

Have n’t you got a lot of Willow material for me? That southern Black 
Willow question is not yet settled. Indeed there is so much work to do in 
the south that I do not know which way to turn. I certainly hope to be 
down in your part of the world again this spring. 

We have received through the Department of Agriculture a specimen of 
Tilia collected at Lake Charles which is perfectly glabrous and looks like 
Tilia floridana. We should investigate it. 

We have had some cold weather and some snow, but it is not as bad as 
it was when you were here last year. 


12 
December 31, 1910. 
I hope you are going to be able this winter to further investigate the 
Louisiana Hamamelis. I am describing the Missouri and Arkansas spring- 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 11 


blooming plants as Hamamelis vernalis. The specimens from Covington 
collected by myself and by you and your specimens from Alto, Richland 
Parish are certainly different in the pubescence from the Missouri plant. 
Of course we have n’t got any flowers of any Louisiana specimen. In the 
Gray Herbarium there is also a Hamamelis collected at Alexandria which 
I suppose is the Richland Parish plant. Why can’t you take up this mat- 
ter this winter and get flowers if possible from all these stations, or at least 
find out whether they do or do not flower in the winter or early spring? 


13 
January 9, 1911. 

Very sorry indeed to hear that you are under the weather. Take care of 
yourself, pray, for there is lots of work ahead of you if we are ever going 
to solve all the mysteries of Louisiana trees. It is my hope and intention 
to pay you a visit this spring either before or after I go to Texas, or at 
both times. I have not formulated my plans yet. 

Mr. Rehder here is working over the North American species of Malus 
and is describing a number of new species and forms. On April 3rd, 1885, 
I collected at Pinnyville [Pineville], Louisiana, which is just across Red 
River from Alexandria, specimens of an Apple growing in a glade in the 
pine woods which we used to refer to Malus angustifolia. I do not believe 
it is that species and probably it represents an undescribed one. It ought 
to be looked up and fruit should be collected. Of the true Malus angusti- 
folia we have from La. two specimens, one collected by me March 26, 1886, 
at Opulusas [Opelousas], and one collected by you at Bayou Lacombe, 
No. 1779. I do not remember where Bayou Lacombe is. Both these Louis- 
jana specimens differ from the specimens of the southeast, Georgia, Florida, 
etc., by the pubescence on the leaves and petioles. I should suppose Malus 
angustifolia would be a common Louisiana plant, especially in eastern 
Louisiana as we have specimens from Pearl River Valley in Mississippi. 
This is a thing which ought to be looked up. 

I have just finished describing seven species of Prunus from Arkansas 
and Texas, and I do not believe that these descriptions cover any of your 
Louisiana trees. Prunus is a genus which certainly has got to be more 
carefully studied in Louisiana. 

I think we have pretty good material of that pubescent Willow but I 
hope you will be able to collect Willows wherever you see them in Louisiana 
as we want more material and more information about these different forms 
of the Black Willow. I am suggesting calling the Bayou Sara tree Salix 
nigra variety altissima, for as it grows at Fulton, Arkansas, this is the 
tallest of all the Willows I have ever known anything about. 

The amount of material we have representing Louisiana woody plants 
is still unsatisfactory and my knowledge about them is even more so. I am 
counting on you for a good deal of help. 

With kind regards and best wishes for the New Year, I am

February 10, 1911. 

I have today your letter of February 6th and the specimen of Oak. This 
looks to us like the tree which they call in England the Lucombe Oak and 
which is supposed to be a hybrid between Quercus Cerris and Quercus 
Suber. Hope you will get plenty of Willow material and the Witch Hazel 
flowers if possible. 

To show how poor we are in Louisiana plants I could not find this 
morning a Louisiana specimen of Liquidambar in our herbarium. 

I am going to Florida on the 18th for a few days and I shall return 
home before going to the southwest. I want to go to Texas before Louis- 
iana, so it will be April, I suppose, before I reach New Orleans. I do not 
care much where I go in the state but we ought to look up that Tilia at 
Lake Charles; and I should like to go, too, to some more places east of the 
Mississippi. Opulusas [Opelousas] is always very interesting to me, so I 
shall be entirely at your disposal. 


15 

February 15, 1911. 
I write another line to remind you that there is a lot to do on Prunus 
in Louisiana in the hope that you may be able to get good flowering 
material from trees so located that we may get fruit from them later in the 
season. This is one of the most difficult groups to work up as the fruit is 
hard to preserve, and it flowers so early that it is necessary to make special 

trips to get them. 


16 
March 6, 1911. 

The two specimens have arrived. Certainly this is not the same as my 
spring-blooming Missouri and Arkansas species which has the inner sur- 
face of the sepals bright red. This plant of yours is remarkable in the 
small size of the flowers and of the fruit which is not more than half the 
size of the ordinary Hamamelis fruit. This may be the variety parvifolia 
of Nuttall, a variety afterwards taken up by Torrey & Gray but dropped 
by recent authors. Judging from the time it flowers, your plant may repre- 
sent a third species; at any rate we have got to know more about it. 

Will you be on the lookout for a yellow-twigged Tree Willow which is 
common in eastern Texas and which you ought to find in the Shreveport 
and western Louisiana region? This is either a species or a good variety of 
Salix nigra and we want to know more about it and to get more material. 

I am hoping now to go to Texas on March 15th and to meet you at Lake 
Charles on my way back, but I will write again before I leave home. 


17 
March 14, 1911. 
I am glad, or perhaps really sorry, to hear that Plum trees are so abun- 
dant in western Louisiana. I am leaving here on Thursday, the 16th, and 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 13 


go via St. Louis to Texas. I cannot exactly fix now the date of our meeting 
at Lake Charles but I will telegraph you from Texas as soon as I know. 
may not be able, however, to send word very long in advance, so I hope 
you will be ready to start at short notice as it will be horrid to be tied up 
alone at Lake Charles. Will you send me a line to the post-office at San 
Antonio in about a week from today and tell me if everything will be all 
right? I think it would be an excellent plan to pay Tracey a visit as I have 
never met him and possibly something might be gained by doing so. 


18 
April 4, 1911. 

I got home safely and very comfortably as that was an excellent train, 
to find here the coldest April Ist on record. The ground is still deeply 
frozen, new ice has formed on the ponds and there is not a sign of leaf or 
flower of any kind. I wish I were back with you in New Orleans. 

Our Lake Charles Tilia differs from Tilia leiophylla in the absence, or 
almost absence, of pubescence and in the serration of the leaves. Tilia 
leiophylla has generally rather coarsely serrate leaves, but in all the Lake 
Charles specimens the teeth are reduced to mucros. Still I think we must 
consider our plant a form of Tilia leiophylia, especially as we have speci- 
mens from Fulton with practically glabrous leaves. It will be interesting 
and important, however, to get flowers and fruit from Lake Charles. 

I have specimens of all the Louisiana Crataegus described by Beadle 
and I feel quite sure that the Lake Charles Crus-galli tree which we saw is 
undescribed. I hope you won’t fail to get the fruit, and I greatly regret 
that we did not get flowers or make specimens. I am quite impatient for 
the specimens of the Crataegus from Covington to arrive for I cannot be- 
lieve that this is C. brachyacantha. The bark is different and the peduncles 
and pedicels are much shorter than those of that species. If it turns out to 
be new, this is one of the most interesting Crataegus discoveries that I 
have made in years. C. brachyacantha is common at Minden and 
Munro[e], and I see that Bush collected it at Natchitoches. 

As you perhaps know four Crus-galli species were collected by Beadle 
near Opelousas. My C. edita appears also to grow there, and of course 
C. berberifolia. About Shreveport there are several Crus-galli species, but 
I think you will find the entire western border of the state full of species 
of this group. 

I am very much interested in that Crataegus with white bark, cordate 
leaves and partly grown fruit which we found on our drive from Covington 
near the schoolhouse. I thought it might be C. silvicola but the leaves as 
I remember them are much too cordate for that species 

I feel quite sure that the Covington Viburnum is V. pubescens. Vibur- 
num dentatum seems to be confined entirely to the Appalachian region. 
T ought to see what you have taken for V. molle. I hope you won’t forget 
good specimens from any localities of the Louisiana Sambucus as this 
genus is pretty puzzling. 


14 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


I have ventured to order and send to you a telescope for your driers 
after the pattern of mine, which has proved very satisfactory in strength 
and lightness. Please accept it in memory of the pleasant days we have 
passed together in Louisiana. Notice, too, that I have had it made much 
deeper than my own and draw from this fact your own conclusions. 

I hope to hear from you very soon about your work since I left. If 
Prunus and Crataegus are to be finished within three years there is not a 
moment to lose. 


19 
April 6, 1911. 
The Vitis which we collected at Lake Charles is V. canescens. You col- 
lected the same thing two or three years ago at Richland Parish and called 
it V. labrusca. I do not see that the books credit Louisiana with V. 
canescens. 
The Highbush Blackberry of which we saw so much at Lake Charles 
and Covington is Rubus Andrewsianus of Blanchard. 


20 
April 19, 1911. 

The package of plants has arrived and I am very glad to see them. The 
Malus from Covington appears to be Malus angustifolia, but we want to 
get good fruiting specimens of this and a handful or two of fruit. It is an 
entirely different plant from the one at Pineville. This I hope you have 
looked up for I very much want to get the fruit, having good flowering 
specimens already. 

The Viburnum from Glen Gordon is not Viburnum pubescens but V. 
scabrellum. 

The Crataegus I cannot distinguish from C. i aaa ae and I be- 
lieve we shall find it has blue fruit. 

The Euonymus from Covington is E. americanus. 

What you call Vitis canescens from Glen Gordon is Vitis cordifolia and 
different from the Lake Charles plant which I told you by mistake was 
canescens. There is no Vitis canescens; it should be V. cinerea. The Cov- 
ington plant seems different from that from Lake Charles. 

The shrubby Vaccinium from Covington is V. stamineum. You have 
also collected this from Shreveport. It is desirable to get good fruiting 
specimens of this 

The Rubus from Claybourne is the same as the tall-growing species 
from Lake Charles. The oldest name for this is R. argutus of Link, which 
must supersede R. Andrewsianus. The little Rubus from Glen Gordon 
with prostrate stems is R. trivialis. The Dewberry from Lake site with 
the large flowers and fruit is, I feel satisfied, an undescribed s 

I hope you found the Malus from Opelousas which, if it is pipet ae 
is a very tomentose form of it. 

I hope you are going to be able to clear up many doubts and mysteries

this season and that you will make good headway with Prunus, Malus and 
Crata 


21 
June 10, 1911. 
Do you know anything about the writer of the enclosed? Possibly he 
may be made useful as a collector or in connection with your proposed 
garden. 
I shall hope to hear from you soon again about the various plants in 
which we are interested. 


22 
July 22, 1911. 

The enclosed may interest you, although I daresay you are in com- 
munication with this lady.* I suppose it was her uncle who was associated 
with Riddell. I know of no other publication by Carpenter. 

How are you getting on and what is the Plum situation? I hope good, 
for in Texas and Arkansas there is no fruit whatever. And how about 
Malus, Crataegus, etc.? 

I hope that you are not worn out by the heat and that I shall soon hear 
from you again. I cannot think that it has been hotter in Louisiana than it 
has in Boston this year. We have never known anything like it or ex- 
perienced such a drought. 

Let me hear from you when opportunity offers. 


23 
August 26, 1911. 

How are you and what is the botanical situation? I hope that you won’t 
be too late for the fruit of Aesculus Pavia from Mandeville as we want it 
for a subject for one of Mr. Faxon’s plates. I think it would be well to 
gather it before it is ripe, although it should be fully grown. Perhaps the 
best way would be to wrap up a fruiting branch in paper and send it by 
mail. This might give better results so far as the drawing goes than a 
dried specimen. 

Any word of the Malus from Pineville which we are very keen to get 
hold of? Prunus in Texas and Arkansas is behaving very badly this year 
and there is no fruit on any of the plants. I hope it is doing better in 
Louisiana. 

I am just back from a short trip to Colorado where I had a few good 
botanical days and from whence I returned via the Great Lakes, which I 
found a most interesting trip. 

24 
December 19, 1911. 

It is a long time since I have heard from you. I hope you are well and 
that the botanical situation is not too much for you.

TER for Mee Cocks (cf. Tulane Graduates Mag. 3: 122. 1914). 


16 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


I was looking at Louisiana Crataegus in the herbarium the other day 
and it is astonishing what a small amount of material we have from that 
state and how little I know about it. The Plums and Apples, too, are 
weighing rather heavily on me. Have you got any more plants to send us 
from this year’s collecting? 

I hope you will have a very pleasant Christmas and a happy and pros- 
perous New Year. 


25 
February 3, 1912. 

It is a long time since I have heard from you but I hope this does not 
mean that you are not well. I hope to be in Louisiana coming from Texas 
early in April and I want to meet you somewhere and make another trip 
with you. I hope you will be able to manage this. 

The Louisiana Prunus situation is in bad shape as only fragmentary 
material has so far been collected. I think it is desirable that you make a 
Plum journey early and before I get to Louisiana, otherwise we shall miss 
them again. For example, numbers 1 and 2 of the Butler plantation were 
well out of bloom on March 28, 1910; from Laurel Hill to Covington we 
have leaves only. +1 from Clear Lake was out of bloom March 30th. 
Shreveport plants were all out of bloom April Ist, and specimens collected 
at Opelousas were out of bloom March 20th. Bush’s collections at Natch- 
itoches April Ist, 1909, were long out of bloom. 

I should think it would be desirable to look over the state for Plums as 
early as March 10th, or perhaps even earlier in the south. The trees should 
be carefully marked to insure mature leaves and fruit later in the season. 

I want very much to go with you to that place north of Alexandria to 
look for the Malus which you have n’t been able to find. I am very sure 
it is an undescribed species. 

As for Louisiana Crataegus the situation, I hope, is not hopeless but I 
think we must confess that we are making very little headway with it. 
Please let me hear from you. 


26 
March 28, 1912. 
I am still pretty shaky but the doctor tells me that I can probably get 
off in a week or ten days for Louisiana. I do not know about the trains 
yet, but would n’t it be feasible for us to meet say at Munroe and drive 
from there to Alexandria? How long would this take and would it be a 
feasible trip? It would at least show me a new country. Or I could per- 
haps get to Alexandria quicker than I could to New Orleans, look up the 
Apple across the river, then go on to Shreveport and Natchitoches, and 
return to New Orleans. 
Let me have an answer to this if you can before I start. If not, I will 
telegraph you when I find out if I can really go and tell you when and 
where I will be.

October 16, 1912. 

Returning from a short journey in Missouri I find your letter of Sep- 
tember 26th and the package of specimens which you have been good 
enough to send us. 

I cannot do much with the Crataegus unless you have the notes on the 
color of the anthers. This is essential to a correct determination of these 
troublesome things. Have you also fruit? I can say, however, that No. 1 
N.O. is C. viridis and xi. and xviii. of Natchitoches are C. brachyacantha. 
C. brachyacantha was the species which we found so abundant a year 
ago last spring near Covington. The Malus and Vacciniums I will write 
about as soon as the specimens are mounted. 


28 
February 18, 1913. 
We have a specimen of a Maple collected by you at Natchitoches April 
27, 1911, with fully grown fruit. It is a very distinct form of the Sugar 
Maple and perhaps an undescribed species. There is nothing like it in our 
herbarium. I am writing to you now to suggest that as this tree had fully 
grown fruit on the 27th of April it must flower very early, probably some 
time before we get to Natchitoches. It is desirable if possible to get 
flowers this spring as we may want to publish a plate of it if it turns out 
to be new. Do you remember the tree? Is it common, etc.? The nearest 
Sugar Maple to this station which we know is at Fulton, Arkansas, and 
there is another at Boerne, Texas, which must be four or five hundred 
miles away. 
What is the prospect of the season, is it going to be early or late? I will 
let you know a few days before I start for New Orleans. 


29 
February 25, 1913. 
I am much obliged for the specimen of Maple which arrived today. I 
think it is safe to refer it to Acer leucoderme Small. 
Please write me again about the season and how vegetation is coming on. 


30 

April 12, 1913. 
We arrived in New Orleans safely but Tracey failed to turn up there. 
From New Orleans we went to Natchez, staying there about thirty-six 
hours and then came home from Chattanooga, arriving here last night. I 
have been quite anxious about you for I am afraid the rain which started 
in after we left Natchez has made a great deal of trouble in the Red River 
Valley and that you are prevented from doing some of the work you were 

going to do. 
I have n’t had time to do much with plants since I got home but the 
Opelousas Malus seems to be very near Malus ioensis var. Palmeri, and 


18 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


the species from Win[n]field to be a form of Malus angustifolia with re- 
markably acuminate leaves. It can hardly, however, be specifically distinct. 
At Natchez we found Hydrangea quercifolia very common. Has this ever 
been found in Louisiana where it ought to grow I should think, but we 
have no specimens from anywhere west of Alabama? I had supposed that 
it was an Appalachian species but finding it at Natchez makes me think it 
may grow south of Natchez and possibly across the river, I also found at 
Natchez what I believe is my Aesculus splendens although I have n’t seen 
the fruit yet and I think that we found the same species at Winnfield. If 
so this is rather a fine plant for the Louisiana flora. That little Viburnum 
acerifolium, if it is that species, is certainly interesting for this appears to 
be an Appalachian species, at least we have no specimens taken west of 
Alabama and none from west of the Mississippi River. These ought to be 
looked up. Although Quercus breviloba is credited in my Manual to 
Louisiana I do not find that we have any specimens of it from that state. 
I should suppose that if it occurs there at all it would be about Shreveport 
as it is common at Fulton. 

I have n’t taken time yet to find out the things which you have n’t sent 
us, but I will write you again next week. Please let me hear what hap- 
pened to you after we parted. I have n’t seen anything so fine anywhere on 
this journey as the woods at Opelousas. 


31 
April 15, 1913. 

A few of the Louisiana plants which we do not have in the herbarium 
are Mimosa strigulosa, Parkinsonia aculeata, Desmodium if there are any 
woody species, and Erythrina herbacea. Have you ever seen this last 
assume the habit of a shrub or small tree, in southern Florida perhaps a 
tree of considerable size? 

Of Quercus laurifolia we have only the specimen with young leaves col- 
lected by us at Lake Charles two years ago. I should be glad to have fruit- 
ing specimens from Lake Charles and from other parts of the state. 

I will send you a list of other Louisiana desiderata as soon as I have 
time to look them up. 

You are O.K. with Prunus Munsoniana. 


32 
April 15, 1913. 

As the copy of your paper, for which many thanks, appeared this morn- 
ing I am afraid you had to shorten your trip and were unable to get to 
several of the places you hoped to visit. Too bad! 

It looks as if we were never going to get at the bottom of the Louisiana 
Crataegus. Mr. Rehder, who is working up Malus, has made a new variety 
of M. ioensis which he calls creniserrata. The type for this is the Pineville 
plant. He refers to it also the Crowley and Opelousas plants. In regard 
to Crowley I find that you are right and that we have fruit from there and 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 19 


some fragmentary leaves. I shall be very glad to get leaves collected now 
with the young fruit, especially leaves of vigorous shoots as it is always 
important to collect these. Your Malus angustifolia from Covington, etc., 
is behaving very badly and does not seem to belong to the typical form of 
that species as it turns out to have hairy pedicels, etc. I wish you would 
collect some more material of this plant from that region with good vege- 
tative leaves, etc. If Malus angustifolia, which we have always believed to 
be perfectly glabrous, is going to behave in this way it will make addi- 
tional trouble for us. 


33 
April 19, 1913. 
As you know, Louisiana was not credited in my Manual for Avicennia 
nitida. We have a specimen from you gathered at Grand Isle. Can you 
give me the range of the species in Louisiana, that is the range east and 
west on the coast? Is it always shrubby in Louisiana or sometimes a tree? 
I do not know where Grand Isle is, but perhaps you will tell me. 


34 
April 21, 1913. 

As I wrote you, we consider the Pineville plant the type of Malus ioen- 
sis variety creniserrata, nov. var. Rehder. The Natchitoches plant which 
we have from you in flower only is referred to this variety although it looks 
a little different. The Opelousas and Crowley plants we now refer to 
Malus ioensis var. Palmeri Rehder. The type of this variety is in south- 
western Missouri, but this form is common in southeastern Missouri and 
in Arkansas. 

You understand that what we have always called Malus angustifolia 
now has to be called Malus coronaria. Rehder makes a new variety of 
this, variety puberula, the type of which is the Winnfield plant. I found 
exactly the same thing at Natchez and we are referring to this variety all 
your specimens from eastern Louisiana. So far as our specimens show we 
have no typical M. coronaria or angustifolia from Louisiana, all your speci- 
mens having more or less pointed leaves and hairy pedicels, while in the 
real coronaria the leaves are usually rounded at the apex and the entire 
plant is glabrous. As I wrote you the other day, I hope you will get more 
material from eastern Louisiana. 

Now in regard to the Crataegus which we collected: Opelousas, #1, a 
Viridis species, by roadside, distinguished from C. viridis by the bark. 
Fruit needed. 

C #2 agrees well with C. tersa of Beadle. 

C +3, the Crus-galli species with small corymbs, does not fit in with 
any described species. Of course we want fruit of this. C +4 we were 
badly fooled by; it is not a Crus-galli at all but C. brachyacantha. 

C #5, a Viridis species. No flowers. 

Winnfield +1. I don’t know this. 


20 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


+2. This was the small slender tree near the quarry, certainly a distinct 
new species. Fruit certainly should be obtained. 

Lake Charles. The thornless Crus-galli in yard on roadside to English 
Bayou. I don’t know this. 

These are all we collected this year. I do not think there ought to be 
much trouble with the Louisiana species if we can only get material for, 
with the exception of C. brachyacantha, apiifolia and spathulata, they all 
belong to the Viridis and Crus-galli, with the exception also of that plant 
we found in western Louisiana which belongs to some other group. It 
looks something like C. silvicola of Beadle. I collected a number of years 
ago specimens of a good many Crus-galli forms from Mendum | Minden] 
which I think is a field which should be investigated. 

I will write you again about Crataegus in the course of a few days. I 
am very anxious to hear from you and what happened to you after we 
separated. 


35 
April 30, 1913. 

Too bad that the weather is so much against us; still if we keep on I 
think we shall get to the bottom of our Louisiana problems. 

I understand that Robin’s Flora is a supplement to his general Travels 
in three volumes, and if the librarian of the Howard Library can get us a 
copy of the whole work I shall be greatly indebted to him and to you. 

We have a wonderful season here this year and have never had so many 
flowers before. 

Better luck next time you start out! 


36 
May 20, 1913. 

I have this morning the package of your plants, for which many thanks. 

Carya Nos. 1 and 3 from Bernice is C. alba. No. 2 from Bernice I don’t 
know. The Carya from West Feliciana, Nos. 1, 2 and 3, I don’t know. 
No. 4, C. alba. No. 5, C. cordiformis. 

When I say I don’t know I mean that I don’t feel sure about this with- 
out more material. Of course we ought to have fruiting specimens in the 
autumn. 

Acer appears to be A. floridanum, and all the specimens of Malus can 
be referred, we think, to M. coronaria var. puberula. The Selma Ilex is 
I. longipes. 

Have you ever found the Hydrangea west of the Mississippi River? 
There is still, I think, two Maples and another Malus to come from Natch- 
itoch. 

I never heard from that banker whom I asked to send the Malus speci- 
men. Can’t you stir him up on the subject? 

Mr. Harbison, who collects for the Arboretum in the southeast, has been 
to Selma this spring to look for the Molles species of Crataegus you told 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 21 


me about and for the //ex. I told him that you had a plantation near 
Selma and he apparently lost a good deal of time in trying to locate it. 
He even went to the court-house to look for a Cocks owning property in 
that part of the world. I suppose the trouble was that the plantation does 
not stand under your name but under that of some member of your wife’s 
family. Harbison will be back there sometime this year and I wish you 
would write me how he can find your plantation and also the exact local- 
ities for the Molles species of Crataegus and for the /lex. 

I hope the world is treating you kindly and that you are coming north 
this summer. There is a lot of work which ought to be done in Louisiana 
in the autumn. 


37 
June 18, 1913. 

I am glad to get your letter. The Holly from Selma is /lex longipes of 
Chapman. 

The last Maple you sent from Natchitoches appears to be Acer leuco- 
derme, but we also have had from the same region from you in previous 
years what must be Acer floridanum; in fact these Natchitoches Maples do 
not behave very well and show a tendency to too much variation. Acer 
nigrum from there we have never seen yet but I hope you will be able to 
get it this autumn. 

I am going to write you in a few days about the Louisiana things which 
especially need looking up this autumn. I am glad in the meantime that 
you are in such a good field as you report Selma to be. By all means send 
the Plums and collect everything woody you can lay your hands on, and 
please pay especial attention to the Hickories. Harbison has been to Selma 
two or three times in the interest of the Arboretum and will be back there 
probably this autumn but I am afraid not until after you have left. 

I gather from your letter that you don’t expect to come north this sum- 
mer. I wish you would let me know about this and, if you are coming, 
when you will be here and how long you expect to stay. I hope in any case 
nothing is going to interfere with work in Louisiana this autumn. 


38 
June 25, 1913. 
I have your note of June 21st and the box of Plums. I do not know this 
plant if it is not a late-ripening variety of the Chickasaw. I suppose you 
are making specimens. I have made out the following memorandum of 
plants in Louisiana which need looking after this autumn: 


Opelousas. 
Crataegus #1, a Viridis species on the bank by roadside east of Opel- 
ousas. 
Crataegus +3, low rich woods fifteen miles west of Opelousas, a tomen- 


tose Crus-galli species. 
Crataegus +£5, a Viridis species in low wet woods, fifteen miles west of 


Opelousas. 


22 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


The Quercus, like the Post Oak, but growing in low wet woods. Mature

Crataegus #1. On road to English — Irish? — bayou. The tree is in a 
yard, about fifteen feet high, with stem a foot in diameter and wide- 
spreading branches. 

Hickory. The tree with pale close bark in the low woods along the river, 
common. The young leaves are bright red. This is probably an unde- 
scribed species and perhaps the same as one of the Hickories in the woods 
east of Opelousas. 

We should have autumn leaves and fruit of the following Hickories: 
Bernice II, West Feliciana; Nos, 1, 2 and 3, Bayou Lacombe, 1785, May 
1908; and #1766, May 1909. 

We need good material of Malus from Crowley and of the two forms at 
Natchitoches, with fruit and leaf shoots. Also from Natchitoches more 
specimens of the three forms of Acer, A. floridanum, A. leucoderme and A. 
nigrum; the last I have never seen. 

I have a great deal of incomplete Crataegus material from Shreveport, 
Munroe, Richmond, Natchitoches and Crowley, but it seems to me that it 
would be better to concentrate this autumn on the things which we saw this 
spring and which I have enumerated above, and try and get these finished 
up. If we don’t begin pretty soon and finish some of these doubtful Louis-

iana trees we shall never get anywhere I am afraid. There are apparently 
more species of Crataegus at Natchitoches than anywhere else in Louisiana 
and of course it is desirable to collect fruiting specimens and number the 
trees this autumn if they are in good condition with the view of completing 
them in the spring, but as I have already said it is most important to finish 
up the things which we got this spring. 

Wistaria frutescens and macrostachya appear to run together and we 
are inclined to consider the latter a variety of the former. I certainly col- 
lected the two plants at Covington. We have no fruiting specimens of 
Wistaria from Louisiana and if you come across any this autumn I wish 
you would make specimens from the different localities.

July 9, 1913. 

Many thanks for the second lot of Plums which have arrived safely. 

I have n’t seen Harper’s Alabama book yet but I believe I have ordered 
it. It is not perhaps surprising that it is n’t complete as his botanical ob- 
servations are chiefly made from the windows of moving trains. 

Have you seen Small’s new edition of The Flora of the Southeastern 
States? I cannot see that he says much about Louisiana plants in it, and 
he has certainly missed all the interesting new things in the way of trees 
and shrubs that have been found in the south in late years. It does n’t 
seem to me that this book, in spite of its great size, adds much to our 
knowledge of the subject. 

I do not believe it is any hotter in Alabama than it has been here during 
the past week and I hope it is n’t as dry there as it is here. 


40 
July 18, 1913. 

I have yours of the 18th and the lots of Plum fruit, for which many 
thanks. Sardis must be a great Plum country, and I hope you are drying 
leaves and making notes of the different forms. 

I am off tonight for Puget Sound, but shall be back at the end of three 
or four weeks. Anything you send in my absence will be taken care of. 

I return Hedrick’s letter. His statement confirms my belief that it is 
impossible to tell much about Plum trees from herbarium specimens alone. 
I cannot believe that Prunus Watsoni grows in Alabama. 


41 
August 15, 1913. 

I am just back from the Pacific coast and find here your letter of July 
17th and the leaf specimens of the Sardis Plums. 

We feel quite sure that your No. 7 is not P[runus] pennsylvanica. I do 
not know what it is but it looks like a new species of Cherry. You better 
send some notes about the size, habitat, etc., of this tree. No. 8 is not P. 
mitis and also looks as if it might be a new Cherry. No. 5 is, as you say, 


24 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


P. umbellata, and I think you are right in referring No. 6 to P. munson- 
tana. | am afraid I cannot throw any light on the other specimens 

The Selma region seems to be a terror for Plums and I hope we shall get 
to the end of them sometime. 

I hope you are all right for the autumn campaign in Louisiana for it is 
important to clear up some of these Louisiana mysteries. By all means 
collect Crabapples from the Selma region. There is probably one new 
species there with leaves very pubescent on the lower surface. 

I’ve just written Harbison to suggest that he go at once to Selma & look 
over the Plum field with you.

W. H. Lamb of the Forest Service of the United States pronounces an 
Ash collected by Dr. J. S. Schenck May 1901 in a Palm Swamp, New Or- 
leans, and previously referred to F[raxinus| profunda, to Britton’s F. 
Michauxti. Do you know anything about this? Specimens of F. Mich- 
auxit which I have seen look distinct. Leaflets on the under surface are 
slightly pubescent and the wing of the seeds is short and broad. This may 

be a good species.

September 24, 1913. 
I find that from southern Missouri I can best reach Louisiana at Mun- 
roe and I suggest that we meet there instead of at Shreveport, then from 
Munroe we can go in either direction. It looks as if I could be there on 
the 8th or 9th of October, but I will telegraph you two or three days in 
advance of my arrival. I think, however, you had best be there on the 

evening of the 8th. 


44 
September 30, 1913. 
In looking over the plant you recently sent we find that the J/ex, a small 
shrub from the banks of the Alabama River, is /lex monticola. There is a 
second specimen of this species from Sardis. The Bumelia is B. lycioides. 
Vitis No. 1 is V. cordifolia. 
Vitis No. 2 is V. aestivalis. 
I am leaving on Thursday and shall be able to telegraph you probably 
from St. Louis two or three days in advance of my reaching Munroe.

October 20, 1913. 
We had a couple of good days with Harbison on Mobile Bay and finally 
got home on Friday. Hickories are very abundant on the shores of the Bay 
and there is but one species there, a Pignut, which shows remarkable 
variation.

The Winnfield Sambucus is S. canadensis variety submollis Rehder, 
which appears to be the common form west of the Mississippi from Mis- 
souri to Texas. The Sambucus which we collected at Opelousas and which 
appears to be common in the neighborhood of New Orleans and along 
Mississippi Sound is Sambucus Simpsonii Rehder, a species first distin- 
guished in western Florida south of Tampa Bay. It is sometimes a small 
tree and appears to be very common in all of southern Louisiana, Missis- 
sippi and Alabama. The Florida plant, as I remember it, did not have 
the bright red petioles, and these were not noticeable in plants which I saw 
about Mobile. The very shining leaves are very unlike those of any form 
of Sambucus canadensis and this I think is a good addition to your Louis- 
iana flora. 

I wish you would dry me a specimen of what they cultivate in New Or- 
leans as Rose of Sharon as I do not seem to be able to place this plant 
from memory. I hope, too, you will send specimens of the different forms 
of Ligustrum which they cultivate i in New Orleans with deciduous leaves, 
and the Araucarias. Indeed we should be glad of herbarium specimens of 
any of the uncommon trees and shrubs cultivated in New Orleans as there 
ought to be representatives in this herbarium of every woody plant cul- 
tivated in the United States 

I will write again soon about some of your other plants. I hope you 
have got over the hardships of Opelousas 


46 
October 25, 1913. 

The //ex with solitary fruit on short pedicels which we collected at 
Winnfield is //ex monticola. This is the first time that we have had any 
indication that this species grows west of the Mississippi River, and Small 
gives its western locality as Alabama. Perhaps this therefore is a new 
addition to the Louisiana flora. 

I think we shall have to call the Viburnum which we supposed might be 
V. prunifolium V. rufidulum as the buds are covered with the rufous to- 
mentum of this species which varies on the petioles. 

I find that there is n’t a specimen of Persea borbonia from Louisiana 
in our herbarium. I suppose it is a common enough tree in the state and 
I wish you would let us have a specimen. I should be much obliged, too, if 
you will sometime take a look at Acer Drummondii as it grows in the 
swamps and give me some idea of the size this tree attains under favorable 
conditions, both in height and trunk diameter, and also some notes on the 
character of the bark. I don’t remember that I have ever been close to the 
tree and if it is to be considered a species I must have more facts about it 
than I have at present.

November 10, 1913. 
We have sent the plants named on the enclosed list to Mr. Marshall, 
Superintendent of the Audubon Park, to whom I also send a list. 


26 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Cupressus funebris is an important Chinese tree which ought to do well 
in New Orleans, and I hope a good place will be selected for it. I don’t 
know as there is much to say about the other plants. 

I will write a line also, as you suggested, to Mr. Morgan, President of 
the Audubon Park Commission. 


48 
November 18, 1913. 

I have your letter of November 13th as well as the Louisiana specimens 
of Hickory. Of Nos. 2, 3 and 7 from West Feliciana there are no nuts, 
No. 2 of course being C. cordiformis. Of No. 3 of Grand Ecore there are no 
nuts. 

No. 6 from Natchitoches looks like C. pallida, and I think No. 2 from 
Natchitoches is the same although there are no nuts of this. No. 7 from 
Natchitoches is C. ovata approaching variety Nuttallii, No. 8 Natchi- 
toches looks like C. ovata but there are no nuts. No. 9 Natchitoches is C. 
myristicaeformis but there are no nuts and we should be glad to have 
them. You speak of having found C. —— at Natchitoches but I don’t 
find either nuts or leaves in the packa 

I feel helplessly confused about oe southern Pignut Group. The more 
material I see the worse the confusion becomes. 

You certainly did not send the specimen of the Oak which you took for 
Q. breviloba. 

I think you had best send me a specimen of your arborescent Alder from 
Selma that I may feel sure of the species. When are you going to send me 
the lists of trees from your Alabama place? Such a list certainly should be 
published. 

P.S. — Please send us some of your printed labels for these last speci- 
mens. 


49 
November 26, 1913. 

I have your note of November 21st and the nuts, for which many 
thanks. We had to use some of your labels with the nuts and I wish you 
would send me about fifty of your blank labels for future use. I will write 
you in a day or two about the Selma Apples and Hickories 

My correspondent in Natchez, who is not a botanist,* has found there 
what I feel quite sure is Carya texana which is called Pignut. My cor- 
respondent writes, — “One who travels in the adjacent Louisiana country 
tells me that the Bitter Pecan or Pignut is thick in the swamps and that 
representatives of German dealers have taken the output of the sawmills 
for use in the making of carriages. The wood is said to be very tenacious.” 
This may be Carya texana and it would be interesting if you could get into 
touch with some one in that part of the state and find out about it. She 
also writes, —‘‘I hear of a nut somewhat larger, thin-shelled and very 
sweet in the West Feliciana Parish.” 

* Miss C. C. Compton. 





1965 | EWAN, LETTERS FROM SARGENT TO COCKS 27 


You once told me that you had heard of a flat Pecan somewhere near 
Baton Rouge and it is possible that this may also be texana which is evi- 
dently much more widely distributed than we had supposed. If it grows 
in Natchez there is no reason why it should not be in West Feliciana. 


50 
November 28, 1913. 
In regard to your Alabama Malus Nos. 1 and 2 appear to be the same 
and look very much like M. ioensis, var. Palmeri, Before we can be ab- 
solutely sure of this, however, we should see the flowers. No. 3 is most like 
M. fragrans, 1 think must be a new species; certainly judging by the leaves 
it is a very distinct form. 


51 
December 3, 1913. 

I am glad to get your letter of November 27th and to hear that the 
plants arrived safely. 

Although I wrote both to the Superintendent of the Park and to the 
Chairman of the Park Commission I have never heard a word from either 
of them. They seem to have curious ways in your town. I understand 
from your letter that the express bill has been settled by the Park people 
and I will interview our expressman on the subject. I do not think the 
plants which you said you sent on “Monday” have yet turned up. 


ae 
December 6, 1913. 

I have your package of plants. The Hibiscus from New Orleans is H. 
mutabilis from southern China. The Oak from Natchitoches, called by you 
Ouercus brevifolia, is Quercus stellata Margaretta, The Ilex Amelanchier 
is all right. This is the first time we have ever had any wild specimen of 
this plant, having known it only from a plant in cultivation. This we have 
lost and we very much want to get it again either by seeds or roots. Pos- 
sibly this can be managed next year. We shall be glad, of course, to get 
flowering specimens. Can you make Harbison understand just where it 
grows? 
i The Viburnum from Natchitoches is V. scabrellum. Your Vacciniums 
Nos. 1, 2, 3 and 5 are V. Elliottii. No. 7 is V. stamineum or one of the 
allied species; and Nos. 4 and 6 are virgatum which has not before been 
in our herbarium from Louisiana. 

Rosa humilis is all right. The Rubus from Winnfield is, so far as we 
know, an undescribed species. We collected the same thing at Washington. 

In regard to your three Acers from Natchitoches No. 1 is floridanum, 
No. 2 leucoderme var., certainly a very curious looking form, and No. 3 
leucoderme like the typical plant. 

I think this will account for all your specimens. I hope you will soon 
send us another supply.

December 20, 1913. 
Your last package of plants has arrived. In regard to Rubus, Nos. 2, 4 
and 7 are R. trivialis; the others all seem to be the common Highbush 
Blackberry which we have collected together. It is nearest R. Andrews- 
ianus, at least it should be referred to that species until the southern Black- 
berries are more critically studied than they have been. 
I find that the older name for Zizyphus vulgaris is Z. sativa Gaertner. 


54 
February 24, 1914. 

Your Cornuses have arrived and seem to be correctly named, except 
what you call C. sericea is C. obliqua or Purpusi, the western and appar- 
ently the southern form of C. amomum, the correct name for C. sericea. 
We have had no specimen of this form so far south and I am glad to 
have it. 

In regard to the Sassafras business, Fernald in the January 1913 number 
of Rhodora has taken up a White Sassafras, first distinguished by Nuttall 
under the name of S. variifolium var. albidum. This variety is distin- 
guished by its glabrous branchlets and leaves which are glabrous when 
young. According to Fernald, it grows from western Massachusetts to the 
Carolina mountains. According to Nuttall, the inhabitants of the Caro- 
linas distinguish the two forms by the names of the White and Red Sassa- 
fras, the root of the White Sassafras being much more strongly camphor- 
ated than the ordinary sort and nearly white. No one says anything about 
the wood of this variety but if the roots are white the wood might be. I 
think it would be well to look at Sassafras in Louisiana and see if you can 
find it with glabrous branchlets and leaves. By the way, we have no speci- 
men of Sassafras from Louisiana. 

I am sorry about the flowers of Acer Drummondii. Have you no speci- 
mens that you can spare us? Does not Acer Negundo grow in eastern 
Louisiana? I have it from the state only from Shreveport and Opelousas? 
I should like to see the eastern Louisiana specimens. There are no speci- 
mens either from Mississippi or Alabama here.

February 26, 1914. 

I have been looking over the Louisiana Hickories and I do not get very 
much comfort from them but send you the following notes: 

Opelousas, East. #5: this is the tree with close smooth bark but with 
the buds, fruit and foliage of the Shagbark, C. ovata. This is the most 
interesting perhaps of the Louisiana Hickories, for if it is a species or even 
a variety it changes all our ideas about the Shagbark Group of the genus. 
If we should consider it a hybrid what would be its parentage? We saw 
but one tree and it is most desirable to locate others in that Group and try 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 29 


to get flowering specimens and young leaves this spring. 1 and 3; on the 
bank of the bayou. We thought these were the same, but notice that the 
rachis and midribs of the young leaves of #1 are very pubescent, and 
that of #3 are perfectly glabrous. #4 appears to be the same as #3. 
+3 and #4 have very large buds and I cannot place them, or #1 either, 
although #1 may possibly be a tree which is common on Mobile Bay. 

Opelousas, West. #1 and 2, the two trees standing near each other in 
an open wood not far from the swamp which you crossed in the spring to 
find the large tree of Crataegus brachyacantha. 31 has pear-shaped and 
+2 subglobose fruit; they are probably the same and I believe an unde- 
scribed species or a form of the Winnfield Yard tree, distinguished by 
hairy branchlets and the yellow scales on the fruit. I have seen what 
seems to be the same thing from Florida and Georgia. It is very important 
to collect these two numbers in their spring condition that we may see if 
the young leaves are covered with yellow scales like those of the Winnfield 
yard tree. +4, “rich woods west of Opelousas; close pale bark; young 
leaves fragrant and red like the Lake Charles tree.” This we did not 
relocate in the autumn. 

Winnfield. The yard tree; this so far as I can tell now is an unde- 
scribed species. We have sufficient material. Like so many other species it 
has both globose and pear-shaped fruit, for I take for granted that the trees 
in the yard are of one species. #2, ‘‘tall tree in woods”. This may be the 
same as the yard tree but I am not sure. The leaves look all right but I 
can find little trace on the buds of the yellow scales which are so con- 
spicuous on those of the yard tree. The fruit of #2 is depressed-globose. 
I should like to see the young leaves of this tree. I do not remember where 
it is. Was it at the last place we went to in the afternoon, in open ground 
on a slope north (?) of the town where we found also a large Plum tree? 
On April 6th at Winnfield, ‘‘in dry woods”, we collected a specimen with 
young leaves white tomentose on the lower surface and only sparingly 
pubescent above. The branchlets are red, slender and glabrous. This I 
suppose is one of the trees in the low ground before we got to the quarry. 
In the autumn we collected in this region C[arya] alba but the tree we 
collected from in the spring is not C. alba. What is it? We missed it in 
the autumn. 

Munroe. In dry woods near Munroe we collected specimens of C. alba 
and of a tree of the Pignut Group with very slender pubescent branchlets 
and small buds; leaves with broad leaflets and pubescent petioles and 
rachis. Old nuts from the ground of what was probably this tree are very 
small. This appears to be a common tree in dry woods near Munroe. I do 
not know it. 

Bernice #2. Only young leaves and flower-buds. Can this be the same 
as the yard tree at Winnfield? The region for it would, of course, be all 
right. It ought to be looked up. 

West Feliciana. #1 looks like C[arya| porcina. The buds are much 
larger than those of the northern tree. #2, no nuts. Can this be the 
Winnfield yard tree? #3, C. ovata, no nuts. #4; the nuts look like those 


30 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


of C. megacarpa. I find no foliage of this. #6, C. porcina? #7 and 8: I 
do not know if these may not be the same as the Munroe Pignut. They 
are pubescent like that tree, but the nuts are much larger than the old 
ones we picked up from the ground. 

Bayou Lacombe. I can say nothing about two very fragmentary speci- 
mens, Nos. 1766 and 1785. 

Lake Charles. I think that we have to begin all over again. You 
turned to the right at the river after passing Irish Bayou and I to the left. 
Along the river I found trees with bright red, fragrant leaves on April 2d, 
and pale close bark. Is it possible to say if the tree you collected from is 
the same? This Lake Charles tree must be undescribed. I believe the 
same thing is west of Opelousas. 

Lucknow.® Of the tree with small, rather thick-shelled pear-shaped fruit

bou 

ane. +1 and 2. I have no idea what these are. #5 seems to 
be a pear-shaped C. alba with rather small buds. #6 looks like C. pallida, 
but it is the only station west of Selma I know for it and it should occur at 
intermediate stations. Does this tree have pale bark and does it grow in 
low ground or on high ridges? I should like to see young leaves. +7, C. 
ovalis with small fruit. #10: I think this is a new species which grows 
also at Fulton, Arkansas. Young leaves and flowers are important as well 
as notes on size, habitat, etc. ¢xi, a pear-shaped ovata! What is the 
bark like. 43, Grandcone.® The fruit looks like that of one of the forms 
of C. ovalis but the buds are covered with yellow scales. Unless it is an- 
other C. pallida it is too much for me. Natchitoches seems to be the storm 
centre for everything that ought and ought not to grow in Louisiana. 

I do not want to describe any new species or varieties of Carya until 
next winter, so that we may have the benefit of another season’s field work. 
It is important that the trees of Lake Charles, east and west of Opelousas, 
Lucknow, Bernice and West Feliciana, should be visited this spring. 
Winnfield is less important and there is still much to be done there. If you 
are able to get good spring material it may be desirable for me to go to 
Louisiana again in the autumn and take another look at some of these 
trees, for I feel that we are not going to get any right conception of them 
except by constant field observation. West of Opelousas there is the new 
apple (#2) of which flowers are needed, and it would be well to get 
apples from Crowley as your correspondent seems to have given out. 

I expect to go to southern Florida this spring, leaving here on the 16th 
of March, and to stop in Georgia and South Carolina probably on my way 
north. You may think that Louisiana Hickories are bad, but I am inclined 
to think that those in south-western Missouri and in the southeastern 
states are even more troublesome. 

Let me hear what the prospects are of your being able to do a good deal 
of field work this spring. Harbison is to go to Selma for your Plum flowers 

*>Sw. of Rayville, Richland Parish.

as soon as he hears from a friend there that the season is opened. I hope 
you do not feel that we know anything yet about the Louisiana Plums. 


56 
April 16, 1914. 

I am back from the south where, although the spring was very backward 
and the weather rather cold, I saw much to interest me and was able to 
extend southward the range of a number of trees. Just before I left I had 
a note from you saying you were sending me flowers of Acer Drummondii, 
but the package has not yet arrived. I suppose it will turn up in time. 

I am inclined to think you are right in supposing there are two quite 
distinct Lindens in Louisiana, one quite glabrous and the other covered on 
the lower surface of the leaves with stellate pubescence. The former is 
well represented at Lake Charles; the latter we found at Winnfield and 
Opelousas, and you found it at Natchitoches. This appears to be the com- 
mon species of eastern and southern Texas, except on the coast where 
Tilia pubescens occurs. It is desirable to get flowers of the pubescent form 
from Natchitoches or some other convenient station. 

I am more than ever convinced how little we really know about our 
southern trees and how much there is still to do. I think I found on the 
Caloos[a}hatchee River in Florida what must be a new Water Hickory or, 
if not a species, a very distinct variety. I see Small credits Louisiana with 
Cyrilla parvifolia but we have no specimens from the state in our 
herbarium. 

I am anxious to hear what success you have had with the Hickories this 
spring. 


57 
May 20, 1914. 

I have taken a look at your Hickory specimens. No. 6 at Natchitoches, 
if the flowers and fruit are from the same tree, is something I do not know 
at all. It has slender branchlets and small buds of a Pignut but the young 
leaves are as pubescent as those of C[arya| alba. The nut is very much 
compressed and the husk splits readily. If there are many trees like this, 
I do not see why it is not a new species. 

No. 10, Natchitoches. Is there not a mixture here? The flowering speci- 
men is C, alba but the fruiting specimen is one of the Pignut group. 

There appear to be no flowers of xi. Natchitoches and 3 Grand Ecore, 
and no fruiting specimens of 12, 15 and 16 Natchitoches and 20 Grand 
Ecore. Note that 12 Natchitoches and 20 Grand Ecore have the yellow 
scales on the young leaves of the yard tree at Winnfield and of the trees 
with the round and pear-shaped nuts of West Opelousas. I should suppose 
there was something in the scales of the young leaves of specific value 

i help us. 
reer B, 9, 13, 14 and xi. seem to be new numbers of which 
there are no fruiting specimens. 


32 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


West Feliciana 10 and 13 are, I suppose, new numbers but we have no 
fruit to match them. I believe that the round and pear-shaped fruits of 1 
and 2, West Opelousas, belong to one species and that there is no charac- 
ter in the shape of the fruit in Hickories. 

I hope you are well and not too hot.

June 17, 1914. 

I have read with much interest your Notes on the Flora of Louisiana, 
No. 1,‘ but why not follow the rules of the Vienna Congress, as you do in 
some cases, and call Quercus acuminata Q. Muehlenbergii and Magnolia 
foetida M. grandiflora? Also why not write “canadensis” in Cercis cana- 
densis with a lower case c when you write caroliniensis with one? 

I do not seem to remember Pinus glabra from West Feliciana. Did I 
have a specimen from there? Of course I know it is in Covington and in 
Jackson, Mississippi. 

I am looking a little into Tilias and I find two specimens of yours which 
I think with our present lights will have to be called T. americana. One 
was collected at Alexandria in June 1905 and the other at Wakefield, West 
Feliciana, June 1907. Unfortunately neither specimen is numbered. Do 
you suppose it would be possible to locate these trees? You once insisted 
that the St. Charles Tilia was different from the one at Natchitoches. 
There are certainly two species at Lake Charles, one like the Natchitoches 
and Shreveport tree with very thin leaves with scurfy pubescence on the 
lower surface which soon rubs off or on some individuals is persistent, and 
the other which is entirely glabrous. The former is T. leptophylla; the 
latter seems undescribed. You collected this last in flower May 12, 1911, 
but not in fruit. We have, however, a poor fruit specimen collected by 
Andrew Allison in the vicinity of Lake Charles (No. 322, no date) which 
came to us from the National Museum at Washington. Do you remember 
the tree from which you collected the flowers and can you locate it? We 
collected on March 26, 1911, Tilia leptophylla at Lake Charles and no 
doubt you were looking for our tree when you made a specimen on May 
12th of that year. This May 12th tree should certainly be looked up and 
investigated further. Tilia leptophylla appears to be the species of Opel- 
ousas and Winnfield, and I presume is the common Louisiana Linden. 

There is a Tilia collected at Selma by Harbison with large leaves oblique 
at the base and covered below with silvery white tomentum, which occurs 
also on the petioles and peduncles, and the young branchlets are stellate- 
pubescent. I do not think that this can be T. heterophylla. The specimens 
were collected May 5th in young bud. This tree should be investigated 
and collected. Is it too late for the flowers now? Fruit, of course, is also 
needed. Judging by Harbison’s material, this tree can hardly be referred 
to any of the described species. It is evident that there are several more 
Tilias in the southern states than were formerly recognized. I am working 
on Hickories and am going to write you about them very soon.

If your wife has been in Washington I presume she has entirely recov- 
ered. I certainly hope so. I hope you are going to have a good summer 
in Alabama. I am going over to England for a few weeks on the 9th of 
July but shall be back in time for the south in the autumn.

une 

I have yours of the 20th and the specimens. The ee eh Poe 
looks like Tilia americana. I suppose for the present, at least, it will have 
to be so-called. Your specimen from Avery Island is not like either of the 
Lake Charles species, and if it is common west of the Mississippi River I 
have not seen it there before. I have seen specimens of what I believe to 
be the same thing from River Junction, Florida. I hope you will gather 
and press a number of specimens with flowers or young fruit of Tilia 
which you say is common on your place, for we have by no means got to 
the bottom of this Linden business yet. 

Your Amelanchier looks most like A. sanguinea which is a northern spe- 
cies. You better send me specimens of your Azaleas or anything else 
interesting. 

Can you not arrange to stop here on your way south from Maine? I 
expect to be back on the 25th of August and it will be a great pleasure to 
see you and your wife here, and it would give us an opportunity to talk 
over many things about the autumn campaign. I suppose you could stop 
in Boston as well on the way south as on the way north. 

I hope I shall hear from you again before I leave on the 8th of July.

: June 29, 1914, 
Many thanks for yours of the 24th with the Lindens. No. 2 certainly 
looks like | Tilia] leptophylla, and No. 3 like Harbison’s plant. This seems 
to me the same as your Avery Island species. If I am right in this it makes 
its distribution from western Louisiana to western Florida. The general 
outline of the leaf looks like that of heterophylla, but the tomentum on the 
lower surface is less dense, and this new tree has more or less pubescent 
branchlets, peduncles, pedicels, etc. The range, too, is quite different and 
I do not see why it is not a good species. I hope you will keep watch of it. 
I want to describe as new a Hickory from Starkville, Mississippi, a 
large tree with dark rough bark and ovate fruit with a husk of medium 
thickness, and a slightly angled nut. The Starkville tree is peculiar in the 
ovalis group, to which it belongs, in the tomentum on the lower surface of 
the young leaflets, and in the dark rough, not scaly, bark. Your No. 10 of 
Natchitoches, although I have no young foliage, can probably be referred 

to this species. Do you remember anything about it? 
I do not remember if I told you that I think we must call the Winnfield 
yard tree and 1 and 2 from West Opelousas C. arkansana. They all vary 
among themselves and from the type, but unless we are going to make a 


34 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


species of practically every Hickory tree a good deal of allowance has got 
to be made for variation. 

I hope you are keeping a sharp lookout for Selma Hickories for I feel 
practically as much in the dark about the southern species as I did two 
years ago. 


61 
July 7, 1914. 
I have yours of the 2d and the package of Lindens. The perfectly glab- 
rous and very coarsely toothed leaves are those of what we have considered 
Tilia americana. 1 think it can be so considered until we find out some- 
thing to the contrary. The species which you have not sent before with 
leaves brownish below and covered with very fine pubescence is Tilia 
Michauxii, and the white-leaved species is certainly the same as that from 
Avery Island and River Junction, Florida. I have n’t seen this tree from 
any part of Louisiana but Avery Island. 
I expect to be back here on the 24th of August, and if by any chance 
your return has been delayed please let me find a letter from you then 
telling me where you are and what your plans are. 


62 
November 6, 1914. 

We got home safely a couple of weeks ago and saw more Hickories in 
Texas and in Arkansas than we did in Louisiana this time. About the 
Louisiana species I shall write you later. 

I have arranged to send Palmer to Natchitoches early next spring and 
to let him make his headquarters there through the season, or long enough 
to solve the botanical problems of that mysterious place. I think we can 
depend on him to make a good collection. 

I wish you would send me a specimen of the arborescent form of Rhus 
glabra either from Alabama or Louisiana. I should like, too, Louisiana 
specimens of the variety of Taxodium which you first reported from the 
state. The further west the specimen comes from the better. I should also 
like to have for purposes of future reference a specimen of Pinus glabra 
from Bayou Sara, as this so far as I know is the extreme western station 
reported for this species. 

We are having wonderful weather here but it is still dry. Do not work 
too hard over your class. Real botany is much more important. 


63 
November 25, 1914. 
Many thanks for the western specimens of Prunus. I hope to live long 
enough to get these things straightened out but the es at present 
does not seem to me very good. It is a tough propositi 
It is not surprising that Carya texana should be Ata near Shreveport. 
I believe it is a very widely distributed tree. 





1965 | EWAN, LETTERS FROM SARGENT TO COCKS 35 


am very sorry to hear about the losses in your family. It is an awful 
business altogether and I am afraid the end is still far distant. 


64 
December 21, 1914. 

I am taking another look at your Prunuses from Alabama and Louisiana 
and report as follows: 

Sardis 1 and 3, P. angustifolia, the latter with unusually broad leaves, 
but I suppose it is a vigorous shoot. 

Umbellata, 2, 4, 5, 8, and 11 from River Road. 

VI., munsoniana. 

15 and 16, leaves only, may be the same. 

VII., the new Cherry, no flowers and the tree destroyed. 

9, evidently the Big Tree Plum. 

Natchitoches 1, munsoniana. 

Natchitoches 6 and 7, only flowers. 

Natchitoches 3, 4 and 5, P. tarda. 

Shreveport 17 and 20, P. tarda. 

Ruston 2, fruit but no leaves. 

10, munsoniana. 

4 may be P. americana. This number is worth looking up. 

9 may be a small-leaved Big Tree but there are no flowers or fruit. 

The common Plum of Louisiana is what we have called for the present 
the Big Tree Plum. I refer the following numbers to it: 20, 21, West Fel- 
iciana. 1, the Butler place. 4, Laurel Hill. Ventree’s Plantation, April 27, 
1910. Laurel Hill, ii., iii. 1, open woods, Hammond. ? Butler place, 2. 
Covington, March 28, 1911. Natchitoches, 11. Ruston, 6 and 8. Ven- 
tree’s plantation, i., ii. Pineville, September 20, 1912. Archibald, 18. 
Shreveport. k., iii. Alta, 93, 14. Clear Lake, 1. Mhoon Plantation, i., ii. 
This is a common tree from Missouri to San Antonio, Texas, and, judging 
from your #9 from Sardis, extends into Alabama, although this is the 
only Alabama specimen I have seen. It appears to vary greatly in the size 
of the fruit, in the time of flowering, and in the time of the ripening of the 
fruit. I tried to make two or three species of it but I am afraid they are 
not very good, with the exception perhaps of P. reticulata which has dis- 
tinctly thicker leaves, smaller flowers and very late-ripening fruit. It 
ought to be possible to find some characters in the bark, and #2 from the 
Butler place may be distinct. 

I do not think the color of the fruit makes much difference in Plums as 
most of the species have red and yellow fruits. Prunus munsoniana is 
probably only introduced into Louisiana and Alabama as it is a more 
western species which has been cultivated for a great many years and is 
beginning to establish itself in many different parts of the country. 

I am still in doubt about the right name for the Big Tree Plum. It may 
be the Prunus mexicana of Watson, based on a very poor specimen of 
northeastern Mexico, or it may be that my Prunus arkansana is the name 


36 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


It is unfortunate that the red-fruited Plum which Bartram found on one 
of the islands off the Louisiana coast has disappeared.* This was described 
by Rafinesque as P. coccinea which, if it is the Big Tree Plum, would be 
the oldest name. It may, of course, have been a red-fruited form of Prunus 
umbellata which appears to be common in the east Gulf States. 

With the compliments of the season and all good wishes for the New 
Year, I am, 


65 
Janu an ine [1915!] 

I can report about your West Feliciana Hickories as follo 

2, 3, 6, 10, 13 and 20 I refer to Carya megacarpa Sevitl although of 
#3 we have no fruit. Next to Carya alba this is the commonest coast 
Hickory from South Carolina to Louisiana, extending into western Mis- 
sissippi and probably into western Louisiana. It appears to run into C. 
porcina and I am now thinking of making both, that is porcina and mega- 
carpa, forms of C. ovalis. 

West Feliciana +1, April and October 1914, which is very pubescent, is 
either another species, or, judging by the nuts, a variety of megacarpa. 
Notice that #1, April 20, 1913, is perfectly glabrous. I have n’t kept this 
specimen. 

#7 and 8 are the pubescent tree like #1 of 1914. 1785 of 1908 is 
evidently the same, but as there is no fruit I have not kept it. 

1766 of 1907 is evidently megacarpa. I have n’t kept this. 

I believe that C. arkansana or C. texana get into Louisiana at Natch- 
itoches but I am not ready to say much yet about the western Louisiana 
Hickories. 

I hope that you are well and that 1915 is going to treat us all better 
than 1914 has, although present appearances for the happiness and pros- 
perity of the world do not seem particularly good. 

P.S.— I suspect that numbers 3, 4, 9, 13 and 14 of East Opelousas are 
the same as #1 of West Feliciana. 


66 


January 7, 1915. 

I have yours of the 14th. Am very sorry to hear about the grippe. 

Prunus is very difficult, especially when one does not see the plants 
growing. I have no doubt from what you tell me that your 1 and 3 of 
Sardis must be separated from angustifolia, for the time of the ripening 
of the fruit certainly ought to have some specific significance. I will look 
at the specimens again. 

It is my plan to let Mr. Palmer, who is collecting for the Missouri Bo- 
tanical Garden and the Arboretum, make his headquarters at Natchitoches 

® Travels 423. 1791. Francis Harper (Naturalist’s ed. Travels 598. 1958) suggests 
Prunus hortulana Bailey. Rafinesque (FI. Ludoviciana 435. 1817) quotes Bartram al- 
most word for word, even to the “subulated point” of the leaf! 





1965] EWAN, LETTERS FROM SARGENT TO COCKS 37 


this year in the hope that he will be able to make a pretty complete collec- 
tion of the flora of that region. As he can reach Shreveport easily from 
Natchitoches I understand it ought to be a good place of operations for 
work about Shreveport and eastern Texas. I think if he can make a good 
collection in that part of the state it ought to simplify work for us in the 
other parishes. I wish you would tell me how early you think he ought to 
get to Natchitoches to get the earliest things, which I suppose will be 
Prunus and perhaps Salix. I should like to have him there early enough to 
get all the Plums as they come into flower. 


67 
January 11, 1915. 

Thanks for your letter received on Saturday. I went to look at those 
Plums again before finally deciding about reticulata, arkansana, etc. The 
type of P. mexicana is in the Gray Herbarium; it is a miserable scrap. 
The leaves look a good deal like what I call arkansana. 

Carya #1 from Lake Charles, the tree with stellate pubescent petioles 
and rachis, young leaves very red and fragrant, growing in low wet ground. 
The branchlets are glabrous but pubescent in your specimen of October 
1913. Is this the same? Flowers have never been collected and are 
needed. Your specimen from Lake Charles, October 1913, is probably this 
#1. I do not know anything like this but we ought to find it in other 
places if it is a species, for Hickories are generally pretty widely distrib- 
uted. We ought to see more of this tree. My only other Lake Charles 
specimen from you is #2, September 1914. I have also two unnumbered 
specimens of fruit collected at Lake Charles by you in 1913; they are both 
pear-shaped and one is much larger than the other. Do you know to what 
they belong? 

+4, east of Opelousas, with red and fragrant young leaves, may be this 
#1 of Lake Charles but the pubescence is quite different. The fruit is 
pear-shaped but then the shape of the fruit does not count for much ap- 
parently. Is n’t #5 from Natchitoches the same as +1 from Lake 
Charles? 

+1 of East Opelousas, the tree with globose fruit, between the road and 
bayou and close to the road, may represent a new species. I do not find 
flowers and young leaves of this. Did you ever collect them? 

This is only a slight dose of what I will give you soon on the Hickory 
situation. If you think the trees in one state are difficult, how about the 
whole country? It is a tough proposition but I hope we are making a little 
headway. 


68 
January 14, 1915. 
I have had to give up the idea of our #5 of East Opelousas as a form 
of C. ovata with smooth bark. The nut is reddish, not white, and not suf- 
ficiently angled for ovata. The leaflets are constantly seven, while it is rare 


38 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


to find seven leaflets in C. ovata and of a different shape; and the branch- 
lets are too slender. I understand that your numbers 9, 13 and 14 from the 
same region are trees with smooth pale bark. 
and 9 from Natchitoches which you think the same as 5 from Opel- 

ousas I believe are C. megacarpa, although the leaves are somewhat pubes- 
cent. The fruit of these numbers is distinctly pear-shaped and shows the 
yellow scales of megacarpa. I hope that in these scales we have found a 
good specific character. I have drawn up a description of Opelousas #5, 
for which I shall propose the name of C. leiodermis. I do not see why it 
has not got to go into a new group but I want to know more of this tree. 

+2 of Natchitoches seems like a tree which is growing at Starkville, 
Mississippi, which I am calling megacarpa stellipila. The fruit of your 
specimen is smaller but the pubescence on the young leaves is the same, 
and your plant is certainly some kind of a megacarpa. 

#¢1, Natchitoches, C. megacarpa. 

+7, Natchitoches, C. ovata. 

#13, Natchitoches, C. megacarpa. 

+10, Natchitoches, the leaf specimen is C. alba, but the fruit under this 
number seems to be C. megacarpa. 

£1, West Feliciana, seems the same as #2 Natchitoches, that is var. 
stellipila. 

+7, West Feliciana, C. megacarpa. 

+8, West Feliciana, seems the same as 1, West Feliciana. 

+4, West Feliciana, of which there is no leaf specimen, is probably a 
megacarpa. Have you leaves of this? If #4 is megacarpa, this leaves none 
of the West Feliciana numbers unaccounted for, but there are still many 
problems west of the Mississippi. 


69 
January 20, 1915. 
I feel sure that there is some mixture in Natchitoches #6. The flower- 
ing specimen seems to be Carya alba, while the mature leaves and fruit 
under this number belong to an entirely different group. I do not suppose 
you remember anything about this. 


70 
January 22, 1915. 
Have you any evidence that Carya cordiformis grows anywhere on the 
Louisiana coast? I have specimens from West Feliciana and from the 
neighborhood of Opelousas. I have nothing from Lake Charles or the 
Covington region. 


71 
January 27, 1915. 
I have yours of the 22d. I have about finished now all I can do on 
Hickories until I get more information and then shall take up the Lindens, 
about which I will write you later.

I should not think there would be any necessity for your going to 
Natchitoches again if Palmer does his work as well as I hope he will, and 
in a week or so I will make suggestions for spring work. I very much hope 
to get to Louisiana myself again this spring for a few days but I do not 
know if I can manage it. If I do, of course we must meet somewhere. 

I am sorry to hear that you are likely to find new Plums in Louisiana, 
the worst proposition that there is. 


72 
January 29, 1915. 

I have yours of the 26th and write to say that I shall be very glad to 
have a specimen of C[arya| cordiformis from the Lake Charles region as 
it apparently is not a common coast tree. 

I have placed the Winnfield yard tree and 1 and 2 from West Opelousas 
with C. arkansana. The Winnfield tree may be all right but I am not very 
well satisfied with 1 and 2. C. arkansana usually grows in high dry ground 
and has dark deeply furrowed bark. These Opelousas trees were in low 
ground and had pale bark. I do not know what else to do with them unless 
to make a new species of them, and I do not like to do this until we can 
find more individuals. This is a thing still to attend to. 


73 
February 6, 1915. 

I have been through the Louisiana specimens of Crataegus again and I 
do not think that the situation is entirely hopeless. The trouble is that the 
plants of which we have insufficient material are pretty widely scattered, 
making it difficult to get what is necessary for their determination. Pal- 
mer will look after Natchitoches and I suppose can get to Shreveport 
where there are still a number of species we do not know. 

I have placed Crus-galli 33 from West Opelousas with C. tersa of 
Beadle which we found in the same locality, and your Crataegus 39 from 
Natchitoches with C. edura Beadle. 

In 1901 I collected at Shreveport a Viridis species which I now think is 
C. velutina Sarg., the type of which grows on the Red River at Fulton; 
and Bush has apparently collected it at Natchitoches “by iron bridge.” 
This is a new species for Louisiana. I collected at Shreveport another 
Viridis species with villose corymbs, color of the anthers not given and no 
fruit. It was in bloom on April 20th and seems distinct. And also on the 
same date another Viridis species with very broad, ovate leaves which had 
been out of bloom, : erie suppose, for two weeks. These two appear to 
be undescribed s 

At Munroe in 1901 I collected sterile branches of a shrub two to three 
feet tall with three-lobed leaves on the young shoots. It looks like a Viridis 
species. What is it? 

From you I have #16 & 23, a Viridis species collected June 1908 at 
Richlands, with half-grown fruit only. Do you know anything of these? 


40 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Natchitoches Crus-galli species. You do not give the color of the 
anthers of xii., xiii., xvi. and xvii. Can you? 

Minden. I have several fragmentary Crus-galli specimens from Minden, 
collected by me in April 1901 and by Bush in August of that year. I be- 
lieve you have never been there. In August Bush collected there “on right 
hand side of road to prairie west of town, just before getting to spring,” a 
Viridis species “with bark and branches rough, dark, scaly and flaky, ex- 
actly as in C. aestivalis which is beside it.” This sounds like the Viridis 
species we saw at Munroe growing with C. aestivalis. The specimens look 
alike. Flowers are much needed. 

Pineville. I collected on April 3, 1885, in bud a Crus-galli specimen 
with small, broadly obovate leaves pale and glabrous below and villose 
few-flowered corymbs, no spines and red branches. Is it not time that this 
specimen should be cleared up? 

You do not give the color of the anthers of your #19 Pineville, April 24, 
no year. 

No number and no fruit from a Crus-galli specimen collected by you out 
of bloom tae 5, 1912. This must have flowered very early for a Crus- 
galli spec 

I collected in 1901 at Shreveport a very narrow-leaved and distinct 
Crus-galli, twenty stamens, color of the anthers not given. 

All the undetermined and undescribed Louisiana species belong to the 
Crus-galli or Viridis groups and there are not many of them. The only 
exception is the plant from Holtonville which had pretty well grown fruit 
on March 20, 1911, and is therefore a very early flowered species. It may 
be a pruinosa but I am not sure. If it is, it is the earliest flowered of the 
whole group and hundreds of miles from any other species of the group. 
This certainly ought to be investigated this year. 

Munroe, where there are also Crataeguses to investigate, Minden and 
Pineville seem to me to be the Crataegus regions for you to visit this spring 
if you can manage it. At Munroe there are Hickories to look for and these 
I will write you about soon. These three places are not very far apart and 
might, I should think, be conveniently taken in on one trip. 

I hope to be able to meet you at Lake Charles, or some other convenient 
place, about the middle of April. 


74 

February 19, 1915. 

I believe now that we have the Hickories from east of the Mississippi 
pretty well in hand with the exception of one or two Alabama and Missis- 
sippi species or varieties, but there is still a bad lot of them in western 
Louisiana, southern Arkansas and Texas. I cannot believe now that 1 and 
2 of western Louisiana can be referred to C. arkansana, variable as that 
species appears to be. The bark and place of growth won’t do. Notice the 
prominent tufts of white hairs on the margins of the leaves of +2 col- 
lected by you in April. These are absent from the young leaves of the 
Winnfield yard tree which seems to be a good arkansana. It is important 


i eee ee 








1965 | EWAN, LETTERS FROM SARGENT TO COCKS 41 


to find more of these West Opelousas trees and to learn something about 
them. Can you undertake this? 

+4 of East Opelousas seems the same as West Feliciana 1 and 8, mega- 
carpa stellipila. 

#1 of East Opelousas I am making a new variety of C. ovalis, var. sub- 
globosa, distinguished by its large fruit and by the stellate hairs on the 
rachis and midribs of the leaves. I am sorry we have no winter-buds of 
this. 

#3 of East Opelousas is a pretty good megacarpa and I am so consider- 
ing it. The buds, however, are very large. 

This seems to clear up East Opelousas, at least for the present. One 
new species and a new variety from there are pretty good I think. 

One of the interesting things to follow up is the tree “in dry woods”’ at 
Winnfield (I suppose this means near the quarry), with leaves hoary- 
tomentose below and slender branchlets. We thought when we collected 
it that it was some form of alba but of course it is not that. It is nearest 
stellipila but that so far as I know never has the dense hoary tomentum 
on the under surface of the leaflets. This is certainly an important tree 
to follow up. 

I will write again on the Lake Charles and Munroe Hickories. 


75 
February 20, 1915. 

I cannot make much out of the St. Charles’ ® Caryas partly because the 
specimens are not all properly numbered. This is my fault, however, at 
least very largely. 

Your #1 of October 1913 is certainly a different species from your #1 
of September 1914. The fruit +1 of October 1914 belongs, I judge, with 
the September specimen although it is marked 1 October. Why cannot this 
be the same as East Opelousas #1, C. ovalis subglobosa? Perhaps my 
specimen collected April 2d, 1913, by river, with bright red unfolding 
leaves may be the same, and I am not at all sure that your specimen 
without number, October 1913, may be the same as your #1 of that date. 
#1 of October 1913 has very pubescent branchlets and buds. I have two 
lots of Lake Charles pyriform fruit from you marked Lake Charles Eng- 
lish Bayou, and West Lake Charles. These are not numbered but perhaps 
you can tell me to which specimen they belong. I fear, however, that the 
whole Lake Charles situation is so mixed up that it can only be straight- 
ened out in the field. 

On April 2, 1913, the Hickory leaves of Lake Charles were nearly fully 
grown. To be really useful they should be collected in an ordinary season 
by the middle of March I should think. Can you run over there for a day 
about that time and get very young leaves of all the Hickories and then 
meet me there about the middle of April? It seems to me that we should 
be there together. 


® Surely a lapse for Lake Charles? 


42 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Carya from Bernice ii. April 9, 1913, is no doubt C. arkansana. I can 
tell nothing about the Munroe material which is too fragmentary. Pos- 
sibly the tree in the field, the first one we collected from last autumn, is an 
arkansana but I am not sure. In these woods there is a small-fruited spe- 
cies with pale bark which I do not know at all. 

If we meet at Lake Charles we might go to Munroe together and then I 
could get into Mississippi without going to New Orleans. Have you ever 
been to Delphi which is east of Munroe, and have you ever collected about 
Fort Hudson? I was there fifty-two years ago but of plants have no recol- 
lection except of the Magnolia which was very fine 

If such curious Hickories are found at Natchitoches, Lake Charles, 
Opelousas and Winnfield, why are there not others in other places in the 
state, and why is it not up to you to look out for them? I hope Palmer will 
pretty thoroughly cover Natchitoches and Shreveport and the regions be- 
tween Shreveport and Texarkana, in Caddo Parish, where I believe that 
some of the Fulton, Arkansas, trees will be found. I believe you have not 
been in that corner of the state and I doubt if this has ever been visited by 
a botanist. So far as I now know the Hickories which need more investiga- 
tion are 1 and 2 of West Opelousas, that is other stations where this tree 
should be found, the Lake Charles and Munroe species, and the tomentose 
Winnfield tree. 

The situation is bad, but not as bad as it was. I hope you will be able 
to make the early visit to Lake Charles.

February 23, 1915. 
I have yours of February 17th about the earliness of the season and am 
writing Palmer to advance the time of his arrival in Natchitoches. 
I am surprised to find that there is no specimen in the herbarium here 
of Castanea pumila from Louisiana where it must be a common tree. 


77 
February 25, 1915. 
Our large Opelousas Malus +2 seems to be the same as the Pineville 
tree which we have called M. ioensis creniserrata. It is certainly a very 
distinct looking form and perhaps when these things are better known 
than they are now would be considered a species. The trouble is that of 
these so-called species of Malus there seem to be many intermediates. 


78 
February 25, 1915. 
We are still in doubt for want of material about the common Malus at 
Selma. Judging by the leaves, it is the same as ioensis var. Palmeri, which 
is the first species which we collected west of Opelousas, and west of the 
Mississippi appears to be a common tree. 
I am afraid Harbison cannot get to Selma this spring. Is there any one

there who could send you the flowers? There might be some one there who 
would know enough to gather them fresh and send them to you for 
pressing. 


79 
February 26, 1915. 
In writing you about Castanea pumila I overlooked the fact that we 
have a leaf specimen collected by you at Covington March 1911. The 
leaves are remarkably glabrous and very green on the under surface of that 
species. Sometime perhaps you will be able to get better material. 


80 
February 27, 1915. 

I have this morning your letter of February 23rd about Lake Charles, 
etc. 

I think now in Hickories that we can put a good deal of reliance on 
characters which have usually been passed over, like the scales on the 
unfolding leaves and on the winter-buds, therefore I think it desirable that 
we should get very young foliage of the Lake Charles Hickories this season 
if possible. That is why I suggested the middle of March but I daresay 
that would be too early. You can judge of that, however, in New Orleans 
much better than I can here. I should like very much to go there with you 
in April for I am particularly interested in those trees, and I think we 
ought to see them together. 

I do not know if it is really necessary to go to Winnfield in the spring 
as we have material of that tomentose plant, but if we are in Alexandria 
and going to Munroe it would not be too much trouble to stop off there for 
a few hours if the trains are running conveniently. I should hate the idea 
of passing a night there. 

The Hickory difficulties are narrowing down now unless some one is un- 
fortunate enough to unearth a new lot of them.

April 23, 1915. 

We got home safely last night direct from Selma via Montgomery. We 
had a couple of days in Selma and of course went out to your plantation. 
I do not think we saw many of the Plums because Harbison did not know 
apparently how to locate them. As he went about with you at Sardis he 
did not pay especial attention to exact localities. We saw your caretaker 
who was much pleased to know that I had seen you so recently and was 
very anxious for news of your wife. We did not get out to the bluffs on 
your place but went to Hatch’s Bluff, which I suppose has about the same 
vegetation as yours. There does n't seem to be but one Tilia there which 
looked very much like No. 2 at Lake Charles, but on the other side of the 
river we found another species with leaves very silvery white and tomen- 
tose on the lower surface, and like one of the Florida and Georgia species. 


44 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


What most interested me at Hatch’s Bluff was a tree which looks like a 
Scarlet Oak but has fruit unlike that of any other Oak I have seen. If it 
is a Scarlet Oak it is certainly a very distinct variety and possibly it will 
have to be called another species. I will send you in a day or two a couple 
of the acorns and cups, and I especially invite your attention to the study 
of this tree. We only saw one specimen which was standing at the edge of 
the bluff about two or three hundred yards, I should think, from the point 
where we reached it across a plowed field close to a negro’s house. 

We saw the Oak which you called Quercus Durandii. It is certainly not 
the Texas tree of that name or one that grows near Columbus, Mississippi. 
I suppose, however, that it may be the Quercus austrina of Ash[e|. There 
was only one Plum in bloom and that was a good sized tree on the left- 
hand side of the road which leads past your place, which we reached by 
turning to the right at your gate. This tree was in the bottom, and in the 
bark looked a good deal like Prunus americana. I will send you in a few 
days a bit of my specimen, also the acorns of the peculiar Oak. 

Another Plum which interested me was a very large tree with dark, 
slightly scaly bark, on the right-hand side of Marion Junction Road, just 
after the crossing of the second bridge on the Orville Road, one mile west 
of the city limits going out by the Orville Road. This is a large tree at the 
foot of a rather steep bank and is rather inclining towards the road; it is 
quite new to me. It was out of flower but I will send you a piece of the 
specimen. Perhaps you will be able to refer these two specimens to some 
of your numbers. 

We found Mississippi and Alabama very hot, dry and dusty, and in our 
minds Lake Charles is still the pleasantest place we saw on this trip. I will 
write you again when I get things somewhat straightened out.

1965] SUSAN DELANO MCKELVEY, 1883-1964 45 


SUSAN DELANO McKELVEY, 1883-1964 


RicHarp A. Howarp 


In JUNE oF 1964, we received from Mrs. Susan Delano McKelvey a 
letter requesting her retirement from the Board of Overseers’ Committee 
to Visit the Arnold Arboretum and from her appointment as Research 
Associate. Mrs. McKelvey stated she could no longer do the things she 
used to do and wished to make way for someone more active in both of 
the roles she cherished. Her wish was a difficult one to approve and so 
these notes were originally prepared in appreciation for service at a 
friend’s retirement. We did not know that time was to be so short, for 
Mrs. McKelvey died on July the eleventh. 

Susan Adams Delano McKelvey was born in Philadelphia, Pennsyl- 
vania, March 13, 1883. She was graduated from Bryn Mawr, married 
Charles W. McKelvey in 1907, and made her home for a number of years 
at Oyster Bay, Long Island. About 1920, she moved to Boston. De- 
termined to study landscape gardening, she consulted Professor Charles 
Sprague Sargent at the Arnold Arboretum, volunteering her services in 
return for instruction in the identification of plant materials. Professor 
Sargent believed in testing volunteers, often with menial tasks such as 
pulling weeds or, in the case of Mrs. McKelvey, washing clay pots in the 
greenhouses. Under the guidance of William H. Judd, who was in charge 
of the greenhouses, Mrs. McKelvey also assisted in plant propagation; 
but she carefully reserved some time for reading, which led to research 
in the library. The famous lilac collection of the Arnold Arboretum was 
being developed, and, at Sargent’s suggestion, she undertook the task of 
compiling information on these plants. The manuscript she submitted was 
of such value that E. H. Wilson added a brief history of the lilac and 
Alfred Rehder a key and a generic description. The horticultural informa- 
tion, the descriptions, and the documentation, however, were the patient 
effort of Mrs. McKelvey. The manuscript was published in 1928 as The 
Lilac: A Monograph. It was dedicated simply to “The Professor.” This 
book, though long out of print, is still the only monograph of a favorite 
among flowering shrubs. 

In the following years Mrs. McKelvey spent some time in the south- 
western United States and became interested in the Yuccas and their 
relatives, often the most conspicuous plants of the drier areas. She 
sought help from various people in the identification of this difficult group 
and in the process learned at first hand how little information was avail- 
able. At the suggestion of Dr. Alice Eastwood, of the California Academy 
of Sciences, she began a diligent study of these difficult plants, photo- 
graphing and collecting specimens for the herbarium and for cytological 


46 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


work. With Karl Sax, then a young cytologist, later to become director 
of the Arboretum, she published a paper basic to the understanding of 
the genus Yucca and its frequent associate Agave. In the study of the 
explorations that led to the discovery of the earlier published species of 
Yucca, Mrs. McKelvey became an authority on the routes of the early 
travellers and the explorers of the great Southwest, thereby uncon- 
sciously laying the foundation for still further research. The first part 
of her work on Yucca was published by the Arboretum in 1938. Its 
acceptance as a scientific study of high quality was soon evident, but 
the years of World War II delayed the issuance of part two until 1947. 

The last of the three books written by Mrs. McKelvey was probably 
the most demanding of her abilities to extract historical, particularly 
botanical, data from general travel accounts. In 1955, the Arnold Arbo- 
retum published The Botanical Exploration of the Trans-Mississippi West, 
1790-1850, by Susan Delano McKelvey. Although a volume of over 
eleven hundred pages, each seemingly with one or more footnotes of 
documentation, the book is an eminently readable account both of history 
and of geographical exploration from the botanical point of view. The 
reviews of this book which appeared in history journals, as well as in bo- 
tanical ones, attest the value of the work with its interweaving of data 
from so many sources. 

For her achievements Mrs. McKelvey was acknowledged and honored 
by horticultural societies and organizations. In 1929, she received the 
Centennial Gold Medal from the Massachusetts Horticultural Society and 
the Schaeffer Medal from the Pennsylvania Horticultural Society. In 
1957, the New York Botanical Garden honored her with the Sarah 
Gildersleeve Fife award given to individuals for work in the field of 
botanical literature. 

Mrs. McKelvey received her first appointment as a research assistant 
to the staff of the Arnold Arboretum in 1931, when Professor Oakes Ames 
was supervisor. It was the privilege of the succeeding directors to con- 
tinue her appointment as a member of the research staff. 

In 1928, Mrs. McKelvey accepted from the Board of Overseers of 
Harvard University an appointment to the Committee to Visit the Arnold 
Arboretum. Rarely did she miss a meeting or an opportunity to lend 
support and to express her interest in the work or the collections. She 
valued the living collections as plants to be enjoyed, as well as to be 
studied. She knew the value of herbarium specimens, and the difficulty 
of preparing them, and was appreciative of good herbarium management. 
Further, she realized the contributory value of cytological and anatomical 
work in her own monographic studies. Thus she fulfilled her duties on 
the Visiting Committee, interested and knowledgeable in the many aspects 
of a modern arboretum 

The association of Susan McKelvey with the Arnold Arboretum was a 
generous one. From her early efforts as a volunteer in the greenhouse to 
her bequest of research materials, her contributions were many. With 
her brother she devoted her energies toward raising a memorial fund to

Professor Sargent which remains a significant part of the endowment of 
the Arnold Arboretum. Through the years, her many gifts of letters and

A primarily pantropical family of about 13 genera with some 700 species, 
a few genera primarily of the North Temperate Zone; four genera in our 
area.* The genus Leea L., of the Old World Tropics, which differs from 
the rest of the family mainly in its nonclimbing habit, sympetalous corolla, 
staminal tube, extrorse anthers, lack of a nectariferous disc, and ovary 
with 3-8 one-ovulate locules, is considered to represent either a subfamily 
of Vitaceae (Gilg) or a family of its own (Suessenguth, Schultze-Motel). 


the corolla (petals free and expanding, or apically connate and forming a 
“cup”), the inflorescence type, and rarely the character of the tendrils, 
also are considered to be of generic significance. Since most of the indi- 
vidual generic characters may vary considerably within and form transi- 
tions between the genera, generic limits are in some cases somewhat un- 
certain. 

Although the vast majority of Vitaceae are sympodial, tendril- -bearing 
vines, there are some tropical tendrilless species with the stems either 
monopodial or sympodial.2 The occurrence of intermediates between in-

florescences and tendrils (e.g., inflorescences sensitive to a contact stimulus 
and performing slight twining movements; those divided into a floriferous 
part and a tendril; or tendrils bearing a few flowers at the tips of their 
branches) is ample evidence for regarding the tendrils as modified in- 
florescences. The tendrils (and inflorescences) are either ‘“continuous” 
(at each of 3—7 or more successive nodes) or “intermittent” (lacking on 
every third node) and are either monochasially 2—12-branched, or some- 
times once or twice forked, or unbranched. The tendrils attach them- 
selves to the support by twining (coiling) or by adhesive discs sad eine 
at the apices of their branches in response to a contact stimulus (e.g. 

most of the species of Parthenocissus; the monotypic Pterocissus Urb. 
& Ekm.; and some species of Cissus and Tetrastigma (Miq.) Planch.). 

Cross-pollination by insects seems to be the rule, although at least in 
some monoclinous or polygamo-monoecious species or varieties self- 
pollination (including geitonogamy) has also ron recorded. 

Floral anatomical data known for a few genera and species indicate 
incomplete septation of the ovary and “anatomically parietal’ placenta- 
tion (Kashyap, 1957; Nair & Mani). 

Chromosome counts made for eight genera (about 57 species) are 
2n = 22, 24, 26, 28, 30, 32, 38, 40, 44, ca. 45, 48, 50, 52, 60, 72, 80, 
96, 98, Suggesting that both aneuploidy and polyploidy have been of 
importance in the evolutionary development of Vitaceae. 

very characteristic seeds of VirompEAE make possible the safe de- 
termination of fossils of this subfamily. The seeds are usually more or 
less oblong-obovate or obovate in outline (or sometimes pyriform and 
distinctly beaked at the micropylar region); the shape in cross section 
depends upon the number of seeds in a fruit. The seed coat is composed of 
a thin, outer, parenchymatous membrane and a hard, usually bony, inner 
layer (sclerotesta). The adaxial (ventral) surface of the sclerotesta 
exhibits a median cordlike to threadlike raphe, extending from the hilum to 
the seed apex and onto the convex abaxial (dorsal) side, where it joins a 
round to linear, depressed to somewhat elevated “chalazal knot.” On the 
adaxial surface the raphe is flanked on either side by a deep groove (an 
infolding of the sclerotesta) varying in shape and length; the endosperm is 
consequently deeply three-lobed on the adaxial side. (See Fic. 1.) 

The family is closely related to Rhamnaceae, from which it differs 
mainly in the predominance of sympodial vines, the hypogynous flowers, 
the predominantly two-ovulate locules, the apotropous ovules, the some- 
what different pollen (similar to Araliaceae rather than to Rhamnaceae), 


leads to the improbable assumption of “extra-axillary’ branches destitute of subtend- 


that, on the contrary, the latter itself requires explanation through comparison with 
the fully doses [mature] state.” (Translation supplied.)

the type of fruit (berry), the usually lobed or ruminate endosperm, and 
the “spatulate” (vs. “investing”) embryo. Together these families con- 
stitute the order Rhamnales. 

It is noteworthy that species of Tetrastigma, and perhaps of some 
other genera of Vitaceae, are the exclusive host plants of the species of 
Rafflesia in Malesia. 

Economically the family is most important for the species of Vitis (q.v.).

and CyPHOSTEMMA Planch. (sometimes segregated as the genus Cypho- 
stemma (Planch.) Alston), of the Old World Tropics, have been recognized. 
Three species of subg. Cissus occur in our area. 

Cissus incisa (Torr. & Gray) Desmoul., marine-vine, a stout vine with 
fleshy, three-foliolate or deeply three-parted leaves, usually occurs on 
limestone in hammocks or in rocky and sandy open woods and on bluffs, 
from central peninsular Florida to Texas, Arizona, and Mexico, north to 
Arkansas, Missouri, and Kansas. Cissus trifoliata L., of the West Indies, 
Mexico (?), and northern South America (?), differing in the always 
three-foliolate leaves with smaller, often flabellate, more regularly toothed 
leaflets, and smaller fruits, occurs in hammocks in southern peninsular 
Florida and on the Florida Keys. The very polymorphic, tropical 
American Cissus sicyoides L., with more or less membranaceous, simple, 
unlobed, medium-sized leaves, and often with long aérial roots, occurs in 
hammocks, from the Florida Keys northward in peninsular Florida to 
Polk County. The inflorescences of this species (sometimes also of C. 
trifoliata) frequently are greatly expanded and deformed by a smut, 
Mycosyrinx Cissi (DC.) Beck, the flowers being transformed into elon- 
gated subcylindrical formations containing spores of this fungus. The genus 
Spondylantha Presi was based on this monstrosity. 

The few published data indicate an “anatomically parietal” placenta- 
tion in a few investigated Asiatic species (Nair & Mani). Chromosome 
counts for 12 species are 2m = 22, 24, 26, 28, 32, 44, ca. 45, 48, 50, and 
96, Suggesting that both aneuploidy and polyploidy have been of im- 
portance in the evolution of the genus. 

The genus is closely related to the monotypic Laotian Acareosperma 
Gagnep., and probably to Cayratia Juss. The genus is in need of a modern 
revision 

The tuberous roots of Cissus trifoliata are reputedly poisonous. The 
aérial roots of C. sicyoides are locally used in Central America for wattling 
baskets, and leaves of this species seem to contain saponines and are 
locally used for washing linen in tropical America.

A genus of about 22 species, of tropical and warm-temperate regions 
of Asia (19 species, centered in China) and North America (3 species) ; 
two indigenous and one naturalized species in our area. Ampelopsis cor- 
data Michx., 2n = 40, a high-climbing, nearly glabrous vine, the leaves 
simple, ovate, cordate or truncate at base, unlobed or slightly 3-lobed, 
coarsely and sharply toothed, the berries greenish or bluish, occurs in 
rich woods and bottomlands from northern Florida to Texas and Mexico, 
north to southeastern Nebraska, southern Illinois, southern Indiana, 
southern Ohio, and Virginia. It seems to be closely related to the eastern 
Asiatic A. brevipedunculata (Maxim.) Trautv. (A. heterophylla Sieb. & 
Zucc.), 2n = 40, a more or less pubescent vine with ovate-cordate, 3-lobed, 
simple leaves and bright-blue berries, which is cultivated for ornament and 
is sporadically naturalized in at least North Carolina and Georgia (Small), 
northward to Ohio and New England. Am~pelopsis arborea (L.) Koehne 
(A. bipinnata Michx.), pepper-vine, 2n = 40, generally a high-climbing 
vine (or sometimes bushy), with bipinnate (or -ternate) leaves, rather 
small, coarsely toothed or incised leaflets, and dark-purple to black berries, 
occurs in swampy woods from southern Florida to Texas, north to Okla- 
homa, Missouri, southern Illinois, and to Virginia and Maryland. It is 


mexicana Rose, of western Mexico (Sinaloa to Guerrero), remain un- 
certain 

Inflorescences showing transitions to tendrils, with a branch or the 
peduncle spirally coiled, have been frequently observed’ in Ampelopsis 
cordata. In at least our species, the septa of the ovary are not connate 
at the center. The genus appears to be homoploid, 2m = 40 having been 
found in the six species investigated. 

A close relationship to Ampelocissus Planch., Vitis, and especially to 
Parthenocissus has been assumed by various authors. The genus is in 
need of a modern revision.

A genus of about 15 species, of the temperate and tropical regions of 
eastern Asia and North America, centered in Asia (12 species); one 
species in our area. 

Parthenocissus quinquefolia (Ampelopsis quinquefolia (L.) Michx., A. 
hederacea (Ehrh.) DC.),* Virginia creeper, woodbine, 2” = 40, occurs 

*Rehder (1905) presented strong arguments for regarding Hedera quinquefolia L. 


as a species of Parthenocissus developing adhesive discs on its tendrils. Consequently 
he applied P. quinquefolia (L.) Planch. to this species. Suringar supported Rehder’s 


iscs, known at present as P. vitacea (Knerr) Hitchc. Rehder’s has generally 
been a American and European botanists, but a few botanists have adopted 
bner’s interpretation. Thus, in his Catalogus Florae Austriae (1 1957), 
Janchen treats P. quinquefolia species without adhesive discs on the tendrils, 
citing in i cea (Knerr) Hitchc. and Hedera quinquefolia L. T 
species with adhesive rece crane known as P. quinquefolia (L.) Planch., Janchen 
c f of escens (Schldl.) Graebner (amplif. Janchen)” with “P. quinquefolia 


Rehder, Schneider, Fritsch, Hegi, Mansfeld, non Graebner” and “non Hedera quinque- 
folia L.” in synonymy. Made in good faith, but hardly well founded, this action un- 
fortunately returns confusion to dc already stabilized nomenclature of the American 
species of Parthenocissus 

Gleason (1947) showed that Vitis inserta Kerner, on which Parthenocissus inserta 
(Kerner) Fritsch is based, “is merely a synonym of P. quinquefolia.’ Hence, the 
correct name for the species known under that name is P. vitacea (Knerr) Hitchc.

in hammocks and woods and on rocky banks from Cuba, the Bahamas, 
and southernmost Florida (including the Keys) north to Maine, Vermont, 
southwestern Quebec, New York, Ohio, Indiana, Illinois, Wisconsin, 
Minnesota, and southern Manitoba, west to Texas, and in Mexico and 
Guatemala (Huehuetenango). The species is variable, and several forms 
and varieties, mostly horticultural, have been distinguished. The most 
frequently encountered wild form of var. guinquefolia is f. hirsuta (Donn) 
Fern. (P. hirsuta (Donn) Small, P. pubescens (Schlecht.) Graebn.), with 
soft-pubescent lower surface of leaflets, young branchlets, and inflo- 
rescences. Parthenocissus quinquefolia var. murorum (Focke) Rehd., 
differing from the typical variety mainly in tendrils with 8-12 short 
branches (as against 3~8 elongated branches) and somewhat broader and 
thicker leaflets, has been recorded at least from Florida, the Bahamas, 
Cuba, and Mexico. The species is closely related to P. laetivirens Rehd., 
of central China. 

Parthenocissus vitacea (Knerr) Hitchc.,4 2m = 40, which differs from 
P. quin quefolia hi in the bifurcately branched corymb-like in- 
florescences (with a tendency toward racemose branching), tendrils 
usually lacking rahe discs, and somewhat larger berries and seeds, 
occupies a range north and west of our area, occurring from Nova Scotia 
and Quebec to southern Manitoba and Montana, south to New England, 
Pennsylvania, Ohio, Indiana, Illinois, Missouri, Kansas, New Mexico, 
western Texas, and Arizona. The closely related P. heptaphyila (Buckl.) 
Britt. ex Small, perhaps a variety or subspecies of the preceding, with 
(6—)7-foliolate leaves and smaller leaflets, seems to be restricted to central 
Texas. 

The flowers in at least our species are proterandrous, and cross-pollina- 
tion appears to be the rule. Bumblebees, honeybees, and some other 
Hymenoptera, Diptera, and Coleoptera have been recorded as pollinators. 
Chromosome numbers, known in four species, are invariably 2m = 40. 
Hybridization (in cultivation, as well as in the wild) between P. quinque- 
folia and P. vitacea, assumed by Schneider (p. 316), can not be sub- 
stantiated at present, since no authentic records of such hybrids have 
been available. 

The genus seems to be closely related to Ampelopsis, as well as to 
Ampelocissus and Vitis. A modern revision of the North American species, 


Suessenguth (p. 312) adopted P. vitacea but made a misleading remark. Having 
questionably placed Ampelopsis quinquefolia DC. var. vitacea Knerr, Bot. Gaz. 18: 
93, in the synonymy of P. vitacea Hitchc., he noted, “fraglich ob hierher gehorig, 


for it to climb a wall or even a tree unless the bark be very ieee owing to the 
structure of its tendrils. It climbs more like the grape and the clem ... On ex- 
amination the tendrils will be found ¥ baad ae like grape tendrils, ait curling and

A genus of nearly 60 species, of temperate and tropical regions of the 


- Northern Hemisphere, centered in China and in eastern North America. 


Two very distinct subgenera have been recgonized, subg. Vitis, 2m = 38, 
comprising the vast majority of species, and subg. MuscapINIA, 2n = 40?, 
including three American species. Morphological differences between the 
subgenera (see below), coupled with different chromosome numbers and 
a rather strong genetic barrier, seem to favor the generic segregation of 
subg. MuscaprntA. Since, however, cytological data are known only in 
one of the three species of the latter, and the morphological differences 
can be evaluated only after a thorough study of the related genera, 
Muscadinia is retained here as a subgenus of Vitis. . 

Subgenus Vitis (§ Euvitis Planch.). Bark of the main stem and bran- 
ches shreddy and exfoliating, without distinct lenticels; pith interrupted 
by diaphragms within the nodes; tendrils forked; infructescences usually 
elongated, many fruited; seeds usually pyriform, + distinctly beaked at 
base, smooth on the abaxial side. About 17 species (or perhaps fewer) in

our area. There is no agreement as to the interrelationships of these; the 
sequence in which they are mentioned below reflects only increasing area 
of occurrence, not taxonomic relationship. The species of subg. Vitis often 
intergrade, and their delimitation appears to be rather difficult; hence the 
species concepts of various authors differ, and the specific status of some 
species is still uncertain. A thorough taxonomic and nomenclatural re- 
vision is needed. 

Vitis illex Bailey (V. cordifolia var. sempervirens Munson), V. Smalliana 
Bailey, V. sola Bailey (apparently closely related to and perhaps conspe- 
cific with V. tiliifolia HBK., of the West Indies, Central America, and 
northern South America), and V. Shuttleworthii House (V. coriacea Shut- 
tlew. ex Planch. 1887, not Mig. 1863) are restricted to Florida. Vitis 
araneosa Le Conte (V. rufotomentosa Small), the specific status of which 
is uncertain, ranges from Florida to Louisiana and southeastern Virginia. 
The Mexican-Texan V. Berlandieri Planch., 2m = 38, and V. candicans 
Engelm., mustang grape, 2” = 38, seem to occur in our area at least in 
western Arkansas. Vitis Lincecumii Buckley, 2n = 38, of Texas, Okla- 
homa, Arkansas, Louisiana, and southeastern Missouri, recently has been 
recorded from Scott County, Tennessee. Vitis Baileyana Munson is found 
in upland and mountain areas in Alabama and northwestern Georgia, west- 
ern South and North Carolina, and eastern Tennessee, north to southeast- 
ern Virginia, West Virginia, and southeastern Kentucky. The taxonomic 
status of V. Lincecumii and V. Baileyana needs further clarification. While 
Gleason (New Britt. Brown Illus. Fl. NE. U. S. 2: 517. 1952) suggested 
that both might be not yet fully stabilized species of hybrid origin, 
Steyermark (Fl. Missouri 1036, 1037, 1040. 1963) reduced them to the 
synonymy of V. aestivalis var. aestivalis and V. vulpina, respectively. 
Vitis palmata Vahl (V. rubra Michx.), 2n = 38, ranges from northeastern 
Texas, northern Louisiana, and central Mississippi north to western 
Oklahoma, central Missouri, southern Illinois and southern Indiana, west 
to southern Kentucky and western Tennessee. Vitis rupestris Scheele, 
sand-grape, 2m = 38, has a similar range, but does not seem to occur in 
Mississippi and Louisiana: reports of this species from Pennsylvania, the 
District of Columbia, and North Carolina appear to be based on intro- 
ductions and escapes.° 

Five additional species of subg. Vitis are of wide distribution in 
eastern North America: Vitis vulpina L. (V. cordifolia Lam.), frost-grape, 
chicken-grape, 2m = 38; V. Labrusca L., fox-grape, 2n = 38; V. aesti- 
valis Michx., summer-grape, pigeon-grape; V. cinerea Engelm. ex Millard 
(including var. cinerea, graybark-grape, 2m = 38, and var. floridana 
Munson, sometimes regarded as a distinct species, V. Simpsonit Munson) ; 
and the most widely distributed species of North America, V. riparia 
Michx. (V. vulpina of authors, not L.), frost-grape or river-bank-grape, 


°In his Spring Flora of the Dallas-Fort Worth Area, Texas, Shinners stated, “The 
name of this species is misapplied by Fernald and Rehder to plants extending north 
through and far beyond our area.” Unfortunately, the basis for this statement was 
not explaine 





1965 | BRIZICKY, GENERA OF VITACEAE 63 


which occurs from New Brunswick and Quebec to Manitoba and Mon- 
tana, south to Virginia, Tennessee, Arkansas, Texas, and New Mexico. 
Vitis argentifolia Munson (V. aestivalis var. argentifolia (Munson) Fern.: 
V. bicolor, of authors) has a range similar to that of V. aestivalis and is 
usually regarded as a variety of it. Since both seem to occur together 
within nearly the same range, it appears to be more appropriate to regard 
V. argentifolia either as a form of V. aestivalis or as a distinct species. 
The latter solution seems preferable until further study clarifies the 
problem. 

Subgenus Muscaprnia (Planch.) Rehd. (Muscadinia (Planch.) Small). 
Bark of main stem and branches close, lenticellate, not exfoliating; pith 
continuous through the nodes; tendrils simple; infructescences very short, 
few-fruited; seed obovate to oblong-obovate, scarcely beaked, usually 
transversely wrinkled on the abaxial side. A strictly American subgenus 
of two or three species, in the southeastern United States, the West Indies, 
and Mexico; two species in our area. 

Vitis rotundifolia Michx. (M. rotundifolia (Michx.) Small), muscadine, 
southern fox-grape, scuppernong, 2m = 40, occurs in hammocks, swamps, 
open woods, thickets, and riverbanks, from southern Florida to Texas, 
northward, mostly on the Coastal Plain, to Virginia, Delaware, south- 
western West Virginia, southeastern Kentucky, Tennessee, extreme south- 
eastern Missouri, and Oklahoma. Leaves in this species are distinctive 
but rather variable; berries are subglobular, 12-25 mm. in diameter, with 
thick, tough, purple-black to bronze (in the cultivar ‘Scuppernong’) skin 
and tough, sweet pulp with a characteristic musky flavor. Long aérial roots 
are often present. This species is highly resistant to virus and fungal 
diseases and insect pests, sisi to phylloxera and nematodes. Vitis 
Munsoniana Simpson ex Munson (M. Munsoniana (Simpson ex Munson) 
Small), closely related to and differing from the preceding mainly in 
the sour, not musky-flavored, black, persistent berries, 8-15 mm. in 
diameter, with a tender skin and pulp and smaller seeds, is found in 
hammocks and scrub, in peninsular Florida and Georgia, on the Florida 
Keys, and in the Bahamas. The leaves, very similar to those of Vz 
rotundifolia, are said to be persistent, at least in southern Florida. Vitis 
Popenoei Fennell (V. vulpina var. yzabalana S. Wats.), of Mexico (Vera- 
cruz) and Guatemala (Izabal), seems to be a distinctive species eyed 
related to V. rotundifolia. However, fruits and seeds, cytology, and dis 
tribution of this species need to be studied. — of V. souendibalin 
from Mexico apparently are referable to V. Popeno 

Although the flowers in the genus usually are 5-merous, the number of 
floral parts (petals and stamens) may vary from three to six (nine), the 


Regarding the distribution of sexes, the plants may be polygamo-dioecious 
(androdioecious; rarely gynodioecious in some cultivars) or trioecious, 


64 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


more rarely dioecious (with only staminate and functionally pistillate 
flowers). Cross-pollination seems to be the rule, although in many culti- 
vated varieties with bisexual flowers self-pollination also occurs. Data on 
pollinating agents of our species are few, but bees seem to be most 
important. 

Chromosome numbers, known in 21 species and numerous diate are 
invariably 2n = 38 in the species of subg. Vitis, and 2 40 in V 
rotundifolia. Polyploidy within the genus is rare, and ce = 57 and 76 
have been found in a few cultivars of V. vinifera. ‘So it is to be considered 
that speciation in this genus is achieved by intrachromosomal variations 
brought about by accumulation of genic differences” (Vatsala). 

Although wild hybrids have rarely been recorded, the species of subg. 
Vitis hybridize freely, and numerous, sometimes complex, artificial hybrids 
between Vitis vinifera and some North American species, as well as be- 
tween some of the latter, have been produced. There seems to be, how- 
ever, a genetic barrier between the species of the subgenera. While the 
cross V. (Muscadinia) rotundifolia 2  V. vinifera 8 has always been 
unsuccessful, the reciprocal cross resulted in a highly sterile F; (2n = 39). 
Two such hybrids have recently been made fully fertile by chromosome 
doubling with colchicine, and a small population of tetraploids has been 
raised from the artificial amphiploids (cf. Dermen, 1964). A complex 
triploid (2n = 59) hybrid, (V. Lincecumii « Labrusca vinifera) @ 
x V. rotundifolia 4, which bears only staminate flowers, has been 
produced. 

A close relationship with Ampelocissus and a more distant one with 
Ampelopsis and Parthenocissus have been assumed by various authors. 
According to Levadoux, Boubals, and Rives, “In the family of Vitaceae, 
it is possible to distinguish a comparium containing the genera with 2” = 
40 chromosomes [Ampelocissus, Ampelopsis, Parthenocissus, and Vitis]. 
In this comparium there appears a remarkable exception, the cenospecies 
Euvitis | Vitis subg. Vitis| to which nearly all the cultivated vines belong, 
and which is characterized by a chromosome number of 2” = 38. The 
linnean species, traditionally differentiated within this cenospecies, are 
ecospecies between which no genetical barrier can be observed.” 

The genus is of great economic importance for the edible fruits from 
which raisins, grape juices, and wines are made. The horticultural varie- 
ties of economic importance have originated from Vitis vinifera (including 
extremely numerous cultivars), V. Labrusca (e.g., cultivars ‘Concord’, 
‘Champion’, ‘Chautauqua’, and others, collectively known as V. labrus- 
cana Bailey), V. aestivalis, and V. riparia, and from crosses between 
certain of these species. In the United States, cultivars of V. vinifera are 
restricted to the Mediterranean-type climate of California; but numerous 
cultivars derived from hybrids of V. vinifera with cultivars of the hardy 
American V. Labrusca are widely grown under the climatic conditions of 
the eastern United States. All of the latter have a characteristic aroma 
and produce wines quite different from those from V. vinifera. Within 
the range of V. rotundifolia its cultivars are widely grown for the fresh

fruit used for home and local consumption and in the production of a 
distinctive wine.

DATES OF PUBLICATION OF THE JOURNAL LINNAEA: 
FURTHER EVIDENCE 


H. E. Moore, Jr., AND C. E. Woon, Jr. 


FOSTER HAS RECENTLY REVIEWED the problem of determining the dates 
of publication of the nineteenth-century periodical Linnaea in which a very 
large number of plants were described and named between 1826 and 1882. 
His list brought together the partial data published by six previous authors 
and other evidence adduced from articles in Linnaea itself, from reviews or 
comments in contemporary publications, and from a few other sources. 
In spite of these detective efforts, accurate dates have been lacking for 
many parts and volumes. 

One of the difficulties in dating this, and a number of other botanical 
periodicals in which the title-page date of a volume may differ greatly 
from that of the actual publication of the individual parts, stems from the 
formerly widespread practice of discarding the covers of the parts when 
the volumes were bound. Thus, the dates of publication of the parts of 
only a few volumes of Linnaea have been taken previously from their 
original covers, these being missing in most sets which have been con- 
sulted. We were therefore happily surprised in August, 1964, when, having 
occasion to check a reference to Linnaea in the library of the Royal Botanic 
Garden, Edinburgh, we found that of the complete run of forty-three 
volumes, twenty-one (20-28, 32-43) have the original covers of the six or 
seven component parts (Hefte) bound in at the back. Each cover is dated 
with month and year and includes a table of contents and sometimes notes 
which provide additional data about the date of publication of the plates 
and the index (Register). Since throughout most of its history Linnaea 
seems to have been behind schedule, these cover dates may reasonably 
be considered the earliest possible for each Heft and should be taken as 
the date of publication, unless other evidence is available, as in the case 
of parts of volumes 42 and 43, the dates of which are given by Van 
Steenis-Kruseman and Stearn as one to six months later than the cover 
date. All other cover dates in the list which follows are in general accord 
with Foster’s list, which in many instances provides the latest possible 
publication date. 

To avoid duplication of effort, it should also be mentioned that we 
examined an incomplete run of Linnaea in the library of the University of 
Edinburgh and that Moore examined two sets at Oxford University (Rad- 
cliff Science Library and library of the Botany Department), but in all 
volumes the original covers are missin 

For convenience, the earlier references to dates of publication of parts 
of Linnaea are repeated here:

COMPARATIVE ANATOMY OF THE LEAF-BEARING 
CACTACEAE, XIII 


THE OCCURRENCE OF WATER-SOLUBLE ANISOTROPIC BODIES 
IN AIR-DRIED AND ALCOHOL-DEHYDRATED LEAVES 
OF PERESKIA AND PERESKIOPSIS 


I. W. Batrey ! 


IN A PRELIMINARY SURVEY of the occurrence of crystals in the leaf- 
bearing Cactaceae (Bailey 1961), I noted the common presence in various 
species of Pereskia of brown isotropic bodies during earlier stages of the 
clearing of leaves in three per cent sodium hydroxide. Although isotropic 
in polarized light, the radial striations and occasional concentricities of 
these bodies superficially resembled those that occur in certain ‘‘sphero- 
crystals’ of calcium oxalate reported upon in the Cactaceae by Mobius 
(1885). They differed fundamentally, however, from the abundantly 
occurring druses and other crystalline forms of calcium oxalate in the 
family which are insoluble and retain their anisotropy in dilute solutions 
of sodium hydroxide. I concluded that the chemical composition and the 
factors involved in the formation of the isotropic bodies merited detailed 
investigation. 

Having obtained more extensive collections of Pereskia, I now find that 
of 14 putative species of the genus all exhibit a tendency to form more or 
less numerous bodies comparable to those previously reported upon 
(Bailey 1961). This is true in the case of leaves from herbarium speci- 
mens of 11 species collected from plants growing in their native habitats 
and, likewise, in the case of leaves of 14 species preserved in formalin 
acetic alcohol (FAA).? Furthermore, the normal living leaves of eight 
species, although they have formed abundant druses of calcium oxalate, do 
not contain such bodies, but tend to develop them when the leaves are air 
dried or are transferred to alcohol varying in dilutions of from 95 to 50 
per cent. 

In the ordinary white light of a microscope the crystalline contents of 
the bodies are colorless. In polarized light they are as strikingly bire- 
fringent as the druses of calcium oxalate (Fic. 1). When dehydrated 


rapidly lose their birefringence and commonly turn brown (Fic. 2). 
Upon prolonged treatment in alkali, the isotropic residues of the aniso-

tropic bodies ultimately lose their striated and other internal structural 
features and dissolve (Bailey 1961, figs. 30-33). This behavior is in 
marked contrast to that of druses and small individual units of calcium 
oxalate which, in the same leaves, remain insoluble and retain their 
anisotropy (Fic. 2). That the birefringent bodies are not composed of 
calcium oxalate is indicated, not only by their behavior when transferred 
to dilute sodium hydroxide, but also by their solubility in water at ordinary 
room temperatures. 

In Pereskia, the size, form, and abundance of the water-soluble bire- 
fringent bodies varies more or less extensively in different collections of 
a taxon, in different leaves of the same plant, and in different layers of the 
same leaf. The larger more conspicuous bodies commonly are composed 
of a group of adjacent cells filled with compact birefringent contents 
which frequently exhibit fine striations oriented radially toward the center 
of the body (Fic. 5). Smaller bodies of spherical or angular form have a 
similar compact crystalline composition, but fewer adjacent cells are con- 
cerned in their development. In some cases, single large independently 
occurring cells of the mesophyll are not completely filled with crystalline 
contents, but may contain one or more small, spherical, radially striated 
bodies or hemispherical striated ones attached to the walls of the cell. 

When many diversely dehydrated leaves of Pereskia are examined, some 
of them contain, in addition to larger bodies, minute water-soluble, bire- 
fringent units diffused throughout parts of the mesophyll (Fic. 4). These 
units vary markedly in crystalline form from rotund to rectangular, dia- 
mond-shaped, slender boat-shaped, and thin angular platelets. Some of 
the larger ones appear to arise by fusion of smaller units forming rings 
or spheres with or without isotropic interiors. These birefringent units, 
not only are water soluble, but also lose their anisotropy and turn brown 
in dilute sodium hydroxide. 

At times, certain crystalline forms of the smaller units tend to be aggre- 
gated in varying degrees of compactness. For example, as illustrated in 
Fic. 3, single diamond-shaped crystals may be surrounded by a layer of 
aggregated crystals of different form. In other cases, groups of adjacent 
cells contain aggregations of small birefringent units in varying degrees of 
compactness. There appear to be transitional forms of crystallization be- 
tween such structures and the commonly occurring extreme form illus- 
trated in Fic. 5. At times, large bodies of the latter general form, having 
compact radially striated crystalline interiors, are jacketed by flat, more or 
less rectangular, birefringent units which are loosely aggregated and hap- 
hazardly oriented. 

I have not encountered slender, much elongated, needle-like crystals 
occurring independently in Pereskia. However, particularly when living 
leaves are dehydrated in 95% alcohol, aggregations of such crystals may 
be formed in a few adjacent cells subtending stomata (Fic. 6). Where the 
elongated crystals are oriented parallel to one another, the aggregation may 
superficially resemble raphides of calcium oxalate, but the fascicles are not 
confined to single enlarged cells (i.e., idioblasts), are not embedded in 


76 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


mucilage, and are water soluble. Very infrequently one encounters a 
radially oriented aggregation of such needle-like crystals in a single un- 
usually large cell of the mesophyll (Fic. 7). 

It is evident from observations recorded in preceding paragraphs that 
the birefringent structures induced during dehydration of the leaves of 
Pereskia exhibit more extensive variability in crystalline form than do 
druses of calcium oxalate persisting from the living condition in the same 
leaves. However, it is significant that, in spite of the diversity in the 
induced forms of crystallization, all of them are characterized by their 
solubility in water and by their similar behavior when transferred to dilute 
sodium hydroxide. It is not obvious at present why some dehydrated col- 
lections of a taxon or clone form the bodies, whereas others do not; why 
some leaves of a shoot contain them, when adjacent leaves are without 
them; and why some parts of a leaf have them, when other parts are 
devoid of them. Nor is it evident what factors are concerned in producing 
the variability in forms of crystallization. More detailed and extensive 
investigations, particularly adequate chemical analyses, starting with nor- 
mal living leaves are highly desirable for elucidating such uncertainties. 

In 36 collections of Pereskiopsis of varying taxonomic affinities, kindly 
collected and preserved for me in FAA by Boke, Moran, Kimnach, and 
others, a majority of 20 has leaves and occasionally young stems containing 
water-soluble birefringent bodies of varying abundance, sizes, and diver- 
sified crystalline forms. The largest of these bodies, up to and exceeding 
600 microns in diameter, are much larger than the largest of those that 
occur in Pereskia (compare the contrasting sizes at the same magnification 
in Fics. 1, 8, & 9). In addition, the larger birefringent bodies of Pereskiop- 
sis differ markedly in their internal crystalline composition from those of 
Pereskia. 

In Pereskiopsis, the larger bodies of multicellular origin tend to be rings 
or disks of varying thickness oriented periclinally in relation to the external 
surfaces of leaves and young stems. They are readily detectable without 
magnification, appearing superficially as embossed white pustules in the 
surfaces of leaves and stems which shrink during dehydration in FAA. 
In some of these bodies, all of the cells in the interior of the body are 
devoid of crystalline content, except for cells which contained druses of 
calcium oxalate in the living leaf or stem. In such a body, the isotropic 
core is jacketed by an anisotropic layer of varying thickness which appears 
as a birefringent ring in polarized light. More frequently the bodies have 
a cell with water-soluble birefringent contents at its center surrounded by 
an isotropic zone (which may contain water-insoluble druses of calcium 
oxalate) and, in turn, by an outer birefringent one having more or less 
numerous outwardly projecting bulges (Fic. 9). Less frequently most cells 
in the interior of a body may contain loosely aggregated water-soluble 
crystals (Fic. 8). 

The individual crystals in these large birefringent bodies vary markedly 
in size, form, degree of aggregation, and orientation. Particularly in the 
outer birefringent zone of the bodies, many of the constituent cells exhibit 


1965 | BAILEY, LEAF-BEARING CACTACEAE, XIII 77 


a conspicuous tendency to contain slender, elongated, more or less needle- 
like crystals oriented radially toward the center of the body. Similar forms 
of crystallization and orientation may be present in the central cell of a 
body. In the case of the large outwardly bulging cells illustrated in Fic. 9, 
some of them may have needle-like, radially oriented crystals in their inner 
or outer parts, whereas remaining parts of the cell contain minute widely 
diffused birefringent specks resembling “crystal sand.”

Some dehydrated collections of Pereskiopsis contain smaller, more 
nearly spherical bodies. Some of these, when viewed in optical section 
(Fic. 10), resemble the larger body illustrated in Fic. 9. A single cell with 
birefringent contents at the center of the body is surrounded by an iso- 
tropic layer and, in turn, by an outer anisotropic one. In other cases, the 
bodies are birefringent throughout, their central part exhibiting very narrow 
anisotropic concentricities partly concealed in Fic. 11 by four positions of 
extinction when viewed in polarized light. The crystalline contents of the 
cell in the center of such bodies may be deposited at times in similar con- 


78 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


centricities (Fic. 10), whereas in other cases the central cell contains 
larger elongated units resembling those that occur in cells of the external 
parts of the bodies (Fic. 11). It is significant in this connection, however, 
that the longer axis of the crystalline units — regardless of extreme varia- 
tions in size and form — tend to be radially oriented toward the center of 
the bodies. It should be noted, in addition, that cells, particularly in the 
interior of the larger bodies, not infrequently contain black granular con- 
tents which tend to obscure internal crystalline configuration when the 
bodies are viewed in polarized light. 

Some of Dr. Boke’s collections of Pereskiopsis preserved in FAA in their 
native habitats (particularly in his B-1, B-18, B-20, B-22, and B-31, with 
putative affinities to P. aquosa, P. chapistle, P. rotundifolia, or P. spathu- 
lata) contain, in addition to multicellular bodies, large independently dis- 
tributed cells with water-soluble crystalline contents. Some of these cells 
(Trext-ric. A) have slender, elongated, radially oriented units resembling 
the configuration that occurs so infrequently in Pereskia (Fic. 7). Occa- 
sionally a large cell may contain several bodies of similar crystalline form 
(Text-Fic. D). The contents of other cells of the same leaf (TEXT-FIG. 
C) commonly exhibit conspicuous concentricities, due apparently to varia- 
tions in the size or form of the crystalline units in successive zones of their 
deposition. In some cases the longer needle-like crystals of the external 
zone extend outwardly into parts of adjacent cells forming expanded bodies 
of more or less conspicuously lobed or angular forms (Text-Fic. E). At 
times, the inner parts of some of the cells contain numerous black isotropic 
specks (TextT-Fic. B) which tend to obscure the anisotropy in the interior 
of concentric configurations. 





DISCUSSION AND CONCLUSIONS 





The water soluble birefringent bodies of Pereskia and Pereskiopsis are 
formed during dehydration of the “sap” of living cells. In Pereskia, the 
larger bodies are remarkably similar regardless of whether leaves are air 
dried, as in the case of herbarium specimens, immersed in 95%, 70%, and 
50% ethyl alcohol, or preserved in FAA. In none of my numerous collec- 
tions of different species of the genus do larger crystalline bodies compara- 
ble to those of Pereskiopsis occur. Although highly variable, the forms of 
crystallization differ so consistently in Pereskia and Pereskiopsis as to 
provide, even in herbarium specimens, an additional criterion for separating 
the genera taxonomically. 

Young green stems in some of my collections of Opuntia (preserved in 
FAA) contain water soluble birefringent bodies of sizes and crystalline 
forms resembling those that occur in Pereskiopsis, suggestive of possible 
taxonomic relationship. Furthermore, the ‘“spherocrystals” in Echino- 
cactus, Mamillaria, and Anhalonium observed and briefly discussed by 
Lauterbach (1889) and Michaélis (1896) were found in tissues treated 
with alcohol. It now appears that these anisotropic bodies, unlike normally 
occurring druses and other forms of calcium oxalate, belong in a special 


1965 | BAILEY, LEAF-BEARING CACTACEAE, XIII 79 


water soluble category. The occurrence of such bodies in all three sub- 
families or tribes of the Cactaceae at least suggests that a tendency for 
their formation during dehydration of the “sap” of living cells may be 
widely distributed throughout this characteristically xerophytic family. 

Since the publication of Schleiden’s (1845) classical paper, the Cactaceae 
have proved to be a family having extraordinarily abundant druses and 
other water insoluble crystalline forms of calcium oxalate in their tissues, 
indicative, in turn, of the production of excessively large amounts of oxalic 
acid in their metabolism. It is significant in this connection that in living 
cacti, crystals of calcium oxalate occur in the mesophyll of leaves (where 
present) and in parenchymatous cells of the pith, cortex, xylem, and 
phloem of both stems and roots. In contrast to this, the water soluble 
crystals formed during dehydration of “sap” in Pereskia and Pereskiopsis 
occur primarily in the chlorenchyma of leaves and in the cortex of green 
stems which function in photosynthesis. 

Unfortunately, owing to numerous complexities and uncertainties, it does 
not appear possible at present to determine the exact chemical composition 
of the water soluble bodies merely by their forms of crystallization. For 
example, upon the basis of superficial resemblances in forms of crystalliza- 
tion, it has been suggested by Lauterbach (1889) and others that the bire- 
fringent bodies in dehydrated tissue of the Cactaceae are composed of 
inulin or related substances. Such is not the case in collections available to 
me where tests for such composition of the crystalline bodies are negative. 
That calcium is involved in the chemical composition of the larger 
birefringent bodies of Pereskiopsis may be demonstrated by treatment in 
sulphuric acid. When transferred to this acid the birefringence of the 
bodies is rapidly reduced, but is quickly restored by the formation of 
crystals of calcium sulphate. The transition to calcium sulphate tends to 
occur more rapidly than in druses of calcium oxalate present in the same 
tissue. 

It is of interest in these connections that similar forms of crystallization 
in alcohol have been encountered in certain representatives of other fami- 
lies of angiosperms, viz. cactus-like euphorbias, Mesembryanthemum 
(Aizoaceae), Basella (Basellaceae), Ceropegia and Stapelia (Asclepia- 
daceae), Galtonia (Liliaceae), and Nolana (Nolanaceae). Belzung (1893), 
Belzung and Poirault (1892) and Mirande (1898), following the earlier 
investigations of Hansen (1888), Leitgeb (1888) and others, concluded 
upon the basis of extensive microchemical and other tests that calcium 
malate and calcium “malophosphate” (?) are concerned in such plants 
during the formation of water soluble crystals when their tissues are de- 
hydrated in alcohol. A similar conclusion was reached subsequently by 
Kean (1931) in his investigation of Mesembryanthemum. ; 

Although these investigations are suggestive rather than conclusive from 
modern chemical points of view, they do indicate that the water soluble 
crystals are in all probability calcium salts of organic acids, occurring in 
close association with calcium phosphate. It is unlikely that the crystals 
are composed solely of calcium phosphate, as suggested by earlier investi- 


80 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


gators, since such crystals are almost insoluble in water as are the crystals 
of calcium oxalate. That dehydration in alcohol is not essential for their 
formation is clearly indicated by their typical occurrence in the dehydrated 
cellular ‘‘sap” of air dried leaves, for example in herbarium specimens. 

At present, cumulative circumstantial evidence from these phylogeneti- 
cally highly specialized genera, in correlation with the behavior in the 
characteristically xerophytic Cactaceae, raises a fundamentally significant 
question. Are there evolutionary changes in the metabolism of angiosperms 
(viz. those having excessive succulence) which lead to the formation of 
unusually large amounts of such organic acids as oxalic, malic, etc.? The 
phenomena are highly complex and variable and involve various uncertain- 
ties. An adequate answer to the question will involve active and sustained 
cooperation between botanists and chemists. 

Preliminary observations on the only normal living leaves of Pereskiop- 
sis available to me thus far (from Dr. Boke’s culture of his B-78) suggest 
that this genus may provide more favorable material for studying succes- 
sive stages in the formation of birefringent bodies during dehydration than 
does Pereskia. A more detailed discussion of the phenomena will be under- 
taken when living leaves and young stems of other species of Pereskiopsis 
become available.

A NEW CUSCUTA FROM NEPAL 
M. L. BANERJI AND SITESH Das 


DuRING THE MONTHS OF SEPTEMBER AND OcTOBER, 1960, while the 
senior author was carrying on botanical exploration in East Nepal, a 
sizeable collection was made which included a conspicuous Cuscuta with 
reddish stem and dark brown flowers, parasitic on Hypericum patulum, 
Banerji 1199. On examination in the herbarium this plant did not agree 
well with any of the known species of Cuscuta. For identification of the 
material constant reference to the monograph of the genus by Yuncker 
(1932) and to Santapau and Patel’s (1957) work on the Bombay Cuscutas 
has been made. Because of the presence of a single style on the gynoecium, 
very careful study has been made of Cuscuta reflexa Roxb., both of mate- 
rial in the Central National Herbarium, Calcutta, and of literature available 
in the Indian floras. By kindness of Dr. S. K. Mukerjee, Keeper of the 
Central National Herbarium, Calcutta, Wallich’s and Hooker’s sheets, 
mentioned by Yuncker (loc. cit.) under reference to C. reflexa Roxb., have 
also been examined, and flowers from these sheets have been dissected and 
studied. As the type of C. reflexa is not definitely known, Roxburgh’s 
Icones have been referred to, as well as Van Ooststroom’s treatment of the 
genus Cuscuta in Flora Malesiana (1955). Our conclusion is that the 
material collected from East Nepal is definitely not C. reflexa Roxb. 

Amongst the Convolvulaceae collected by Zimmerman in 1954 in Nepal, 
very kindly sent by the Director, Conservatoire et Jardin Botaniques, 
Genéve, to the senior author for determination, is a Cuscuta, Zimmerman 
1302, which is exactly the same as Banerji 1199. 

In the Central National Herbarium, Calcutta, is a sheet, Burkill 35707, 
from Dibrugarh (Assam) which, although named Cuscuta reflexa Roxb., 
is quite different from other sheets so determined. Further, this specimen 
of Burkill’s superficially resembles the present materials from Nepal in 
characters of calyx, size of corolla, and position of the anther lobes. It is 
pertinent to mention that on this sheet (Burkill 35707) is a sketch of the 
characteristic globose-shaped gynoecium. A close examination of the 
flowers revealed a gynoecium with a prominent style 0.5—0.75 mm. long, 
in both the Nepal specimens and in Burkill’s material. The infrastaminal 
appendages have also been found to differ from those of C. reflexa Roxb. 
A study of the pollen grains, made by the junior author, showed marked 
differences, too. Pollen from Wallich’s and Hooker’s materials has been 
found to measure 27.2, while the pollen from the Nepal materials meas- 
ures 30.4y in diameter in polar view. With such marked differences from 
C. reflexa Roxb., it seems best to treat these materials collected from 
East Nepal and Assam as a distinct new species.

Annual or perennial herbs, shrubs, trees, or vines, often with conspicu- 
ously swollen nodes, the nodes completely or partly surrounded by a mem- 
branaceous or scarious sheath, the ocrea, or this reduced to a row of hairs 
or completely wanting in a few genera. Leaves entire [rarely pinnatifid or 
palmately cleft], alternate or whorled [or opposite], petiolate to sessile, 
membranaceous to fleshy or leathery, occasionally articulated at the base 
with the stem. Inflorescences diverse, the flowers seldom solitary, mostly 
clustered into few-flowered fascicles, each fascicle subtended by a bract 
and each flower by a persistent sheath (ocreola) and occasionally also by 
2 scarious bractlets; rarely fascicles subtended by and partly included in 
an involucre, the flowers subtended at the base only by numerous bractlets. 
Flowers regular, with a variable number of parts, mostly 3- or 5-merous, 
bisexual or unisexual, the base (receptacle?) narrowed into a short or 
long stipe which articulates with the pedicel. Tepals (2—)5 or 6, in 2 


species outside this area, and references marked by an asterisk have not been seen by 
the authors.

Predominantly of the North Temperate Zone, consisting of about 30 
genera and 700 species; represented in the southeastern United States by 
seven genera. The family is a very natural and easily recognized one, but 
infrafamilial categories are much debated. At least five major classifica- 
tions, none of which is entirely satisfactory, have been proposed (cf. 
Meissner, Bentham & Hooker, Dammer, Gross, and Jaretzky). The 
classification of Gross, which seems to be most in accord with the com- 
monly accepted relationships of the genera, is followed here, although the 
subfamilial sequence is not considered by the writers to be an expression of 
the order of evolution within the family. 

Two genera, Fagopyrum Mill. and Emex Campd., included in Small’s 
Manual of the Southeastern Flora, are not known to be naturalized in the 
Southeast. Fagopyrum esculentum Moench (F. sagittatum Gilib., Poly- 
gonum Fagopyrum L.), buckwheat, 2m = 16, grown extensively as a 
grain in Russia, is cultivated to a limited extent in the United States. 
Although escaping to roadsides and other disturbed areas, it probably 
does not persist for more than a season, at least in our area. The genus 
is included, however, in the key to genera because of its occurrence as a 
waif. The Mediterranean Emex spinosa (L.) Campd. is a waif evidently 
rarely introduced as seed in ballast but apparently not persistent in the 
Southeast. 


Various authors have related the Polygonaceae to several families, in- 
cluding the Chenopodiaceae, Phytolaccaceae, Basellaceae, and Caryophyl- 
laceae, mainly on the basis of the unilocular ovary and single basal ovule.

1965] GRAHAM & WOOD, GENERA OF POLYGONACEAE 93 


The family is now generally regarded as derived from and advanced over 
the Caryophyllaceae. 

Floral anatomy of the Polygonaceae has been studied intensively. The 
most recent workers, Laubengayer and Vautier, agree that the basic floral 
plan is three-merous, with whorled parts, as in Eriogonum and Rumex, 
and that the five-merous condition, found, for example, in Polygonum, is 
derived. In five-merous flowers one tepal is bivalent, as shown by its 
position partly in and partly out of the two whorls of tepals and by its 
two vascular traces. (In some cases, the second trace may be reduced or 
missing, but the tepal generally remains intermediate in position between 
the two whorls. ) 

According to Laubengayer, the unilocular, uniovulate ovary was derived 
from a multiovulate gynoecium with free-central placentation by suppres- 
sion of the lower portion of the ovary and by adnation of the lower part 
of the placenta to the lower ovary wall. The “funiculus” is, then, the 
remaining portion of the free-central placenta. Joshi, however, believes 
the ovule is borne on a true funiculus, with only the basal end of the stalk 
perhaps representing a vestige of a free-central placenta. (See Lauben- 
gayer and Vautier for summaries of the views of other authors on various 
aspects of the floral anatomy.) 

The characteristic ocrea of the Polygonaceae has been interpreted vari- 
ously as an outgrowth of the sheathing base of the petiole, as the product 
of the fusion of either a row of adjacent stipules or two lateral stipules, or 
as an expanded axillary stipule. 

The pollen morphology is extremely diverse. The basic type from 
which others are thought to have been elaborated is ellipsoid, heavy- and 
smooth-walled, and has three long furrows, each with a central germ pore. 
It is found in such entomophilous genera as Eriogonum, Fagopyrum, and 
Antigonon, and in some insect-pollinated species of Polygonum. Evolution 
of the pollen grain is thought to have proceeded from this in two direc- 
tions: in insect-pollinated species (such as Polygonum Persicaria), toward 
further elaboration of exine sculpture with concomitant reduction of fur- 
rows and increase in number of pores, and in wind-pollinated species 
toward reduction in number of pores and the thickness of exine, and loss 
of furrows. 

The family is of minor economic importance, including a few food plants 
(e.g., Fagopyrum, Rheum Rhaponticum L.), some tropical timber trees, 
a number of ornamentals, and some noxious weeds. Fagopyrum was 
formerly the major commercial source of a flavonol, rutin, which 
strengthens capillary blood-vessel walls, preventing hemorrhage in victims 
of high blood pressure (cf. Couch, Humphreys).

A North American genus of about 150 species in four subgenera and 
14 sections, best developed in the western United States and well known 
for the taxonomic difficulties it presents. The four species occurring in 
the Southeast belong to subg. ErtoGonuM (subg. Eueriogonum S. Wats.) ,? 
comprised of perennials with turbinate involucres without angles or 
nerves and two to five or more foliaceous bracts, and sect. ERIOoGONUM 
(§ Eriantha Benth.), having flowers with a stipelike base, achenes not 
winged, and embryo straight, centered in the endosperm. 

Most widespread in the Southeast is Eriogonum tomentosum Michx., 
occurring from South Carolina to Florida along the sand hills of the inner 
part of the Coastal Plain. It is easily recognized by the dense, brown 
tomentum on the undersurface of the leaves and by the whorled cauline 
leaves. The three other southeastern species, E. longifolium Nutt., E. 
Harperi Goodman, and E. floridanum Small, have white pubescence and 
alternate cauline leaves. They and the eastern Texas E. vespinum Shinners 

*It is not clear ge the names proposed by Watson (1877) were meant to be 
subgenera or sections. He refers to them as sections and indicates to which section the 
earlier names of Saehini (1856) and Torrey & Gray (1870) _belong. The rank of

subgenera and Bentham’ s and Torrey & Gray’s as section. 


98 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


are morphologically so similar that maintenance of four species is highly 
questionable, and a re-evaluation of their taxonomy is recommended. 
Eriogonum longifolium occurs in Texas, Oklahoma, Kansas, southern 
Missouri, and Arkansas, while E. Harperi is described as endemic to Col- 
bert and Franklin counties in northwestern Alabama. Specimens examined 
from the area of Hot Springs, Arkansas, are difficult to place in either. 
Eriogonum floridanum, endemic to central peninsular Florida, differs from 
the preceding two species in having generally larger flowers, 6-10 mm. 
long vs. 4-8 mm. long, with very long pedicels (exceeding 1 cm.) in pe- 
dunculate, rather than nearly sessile, involucres. Eriogonum vespinum 
is distinguished from EF. longifolium only in being less densely pubescent 
and having slightly longer peduncles and floral stipes. 

Chromosome numbers, mostly undocumented, of several species of the 
western United States have been reported (2m = 18, 22, 24, 32, 34, 40, 
and 80), the most common number being 2” = 40. At least two western 
species, Eriogonum fasciculatum Benth. and E. nudum Dougl., include 

lyploid races of 2n = 40 and 80. The basic gametic number is thought 
to be x = 10, with hybridization and aneuploid increases and decreases 
accounting for the wide range of numbers. Natural hybrids of several 
species are known or suspected, but production of artificial hybrids is 
hampered by the difficulty of emasculating the small flowers, each of 
which produces but a single seed ; 

The genus is considered to be closely related to the endemic American 
Chorizanthe R. Br. and Oxytheca Nutt., the only other members of the 
family with involucrate, nine-staminate flowers.

Thirteen to fifteen species in three of the four subgenera occur in the 
southeastern United States. Several species are widely distributed as 
noxious weeds of cultivated ground and roadsides. 

Subgenus RuMEx (subg. Lapathum Pers.) is comprised of annuals and 
perennials, with leaf bases round to cuneate, never sagittate or hastate, 
flowers bisexual and inner tepals with or without callosities. The chromo- 
somes are the smallest in the genus, x = 10, and 2m ranges from 20 to 
200. Polyploidy and inter- and intraspecific hybridization have been re- 
ported in both sections of the subgenus. 

In sect. RuMEXx (§ Simplices Rech. f.), the single stem is unbranched 
with a terminal inflorescence. The six species of this section which oc- 
cur in the southeastern United States are of European origin and are 
highly polymorphic, mostly with several subspecies. Rumex crispus L., 
2n = 60; R. pulcher L., 2n = 20; and R. obtusifolius L., 2n = 40 and 60, 
are widespread in the United States. Growing along roadsides and in 
waste places throughout our area, they are occasionally sympatric (€.g., 
in New Orleans, Louisiana; Tallahassee, Florida; and Granger and Hawk- 
ins counties, Tennessee). Putative natural hybrids of R. crispus X 
R. obtusifolius have been reported from Louisiana and of R. crispus 
R. pulcher from Virginia. Rumex crispus in Great Britain is composed 
of several races, all evidently interfertile (Rechinger, 1961). Although 
widely distributed in the northern and western states, R. conglomeratus 
Murr., 2m = 20, appears in our area only in the more easterly parts of 
North Carolina. Also common elsewhere in the United States but of limited 
distribution in the Southeast are R. Patientia L., 2n = 60, known from 
scattered localities in Tennessee and North Carolina, and R. mari- 
timus L. var. fueginus Dusén (confused by Small with R. persicarioides 
L.), 2m = 40, reported from Little Rock, Arkansas. According to Rech- 
inger (1937), R. sanguineus, 2n = 20, is probably not present in the 
Southeast but has been confused by American taxonomists with R 
conglomeratus. 

Section AxILLarEs Rech. f., characterized by plants with leafy axillary 
branches and secondary inflorescences, has its center of development in 
North America. Extra-American species are believed by Rechinger, on 
the basis of their isolated systematic position, to be relics of ancient lines 
of evolution. Seven species of this section have been collected in the 
Southeast, but R. mexicanus Meissn. and R. cuneifolius Campd., native 
to Mexico and South America, respectively, are known from limited ma- 
terial which suggests they are not established introductions. Rumex 
verticillatus L., 2n = 48, 60, R. floridanus Meissn., and R. fascicularis 
Small, restricted to the Atlantic and Gulf coastal plains, are distinguished 
from one another on the basis of slight morphological differences which 
scarcely support specific rank. Also occurring on the Coastal Plain in 
Louisiana is R. chrysocarpus Moris (R. Berlandieri Meissn., R. Langloisit 
Small). Rumex altissimus Wood, 2n = 20, widely distributed in the 
eastern and central United States, is known from most of the Southeastern 
States, generally occurring inland from the Coastal Plain. Several experi-

mental crosses made among species in the section (see Sarkar) show a 
high degree of pairing and good seed-set in the F; generation of the dip- 
loids, but completely sterile triploid and tetraploid hybrids. 

Subgenus Acetosa (Mill.) Reichenb., morphologically and cytologically 
the most variable subgenus, includes about 40 species in six sections, with 
a predominantly Old World distribution (most abundant in northern and 
eastern Africa, southern Europe, and the Middle East). The plants are 
shrubs or perennial or annual herbs and are hermaphroditic or dioecious, 
commonly with hastate or sagittate leaves, and inner tepals much longer 
than the achene and mostly without callosities. Chromosome numbers 
vary from 2m = 8 to 40. The dioecious annual, Rumex hastatulus Baldw. 
ex Ell., 2n = 8 2,9 $,or2n = 10 2,10 4, is the only member of sect. 
ACETOSA subsect. AMERICANAE Live & Sarkar; its nearest relatives are 
the western American R. paucifolius Nutt. ex S. Wats. (§ Paucifoliae Live 
& Sarkar) and the Old World R. Acetosa L. and R. thyrsiflorus Fingerh. 
(§ Acetosa), both with 2n = 142, 154 and adventive in northeastern 

merica. Rumex hastatulus is widespread in sandy soils of the Coastal 
Plain from North Carolina to northern Florida, west to Texas and Okla- 
homa, and occurs in the adjacent Piedmont on disturbed, well-drained sites. 

Sex determination in Rumex hastatulus, R. Acetosa, and R. paucifolius, 
2n = 14 and 28, has been studied by several workers. An X/A balance 
mechanism of sex determination similar to that originally discovered in 
Drosophila occurs in R. Acetosa, with sex expression determined by the 
ratio of autosomes to X chromosomes, the Y chromosomes having no effect. 
Sex expression in R. paucifolius appears, on the other hand, to follow the 
more primitive X/Y scheme, discovered in Silene (Melandrium) and de- 
scribed later in R. Acetosella, in which strong male factors are located in 
the Y chromosome and the effects of the autosomes are secondary to the 
influence of XX versus XY. 

Two karyologically distinct races differing in sex-chromosome mor- 
phology and chromosome number occur in Rumex hastatulus. The differ- 
ences in karyotype have involved loss of one autosomal pair and the 
appearance of multiple Y chromosomes, changes which Smith has postu- 
lated to be the result of two successive translocations. Populations from 
North Carolina to Florida and Mississippi have a modified X/A mech- 
anism (2n = 6 + XX 9 and 6 + XY,Yo2 4 ). Although sex is determined 
primarily by the ratio of X chromosomes to autosomes, the Y chromosomes 
are not entirely neutral but contain a region which enhances the expression 
of maleness. Populations from Louisiana and Texas to Oklahoma and 
Arkansas have ten chromosomes in both sexes (27 = 8 + XX @ and 8 + 
XY 4). The genetics of sex determination in this western race have not 
yet been analyzed. ; 

Staminate plants of Rumex hastatulus are “heterogametic,” producing 
male- and female-determining pollen in equal numbers; carpellate plants 
are “homogametic.” In North Carolina, carpellate plants (57%) are 
more abundant than staminate (43%). Smith has suggested that the 
disparity in sex ratio in R. hastatulus may be attributable to a differential 


102 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


selection favoring either the female-determining pollen or the female- 
determined embryos prior to the seedling stage, a phenomenon which has 
been demonstrated in R. Acetosa and in other dioecious plant species. 
Apogamy occurs in a few species of the subgenus but accounts for only 
an estimated 1-2% of seed-set. 

Subgenus AcETOSELLA (Meissn.) Rech. f. consists of a polyploid series 
of perennial dioecious herbs with hastate or ‘sagittate leaf bases and 
callus-free tepals which generally do not exceed the achene. One to four 
species are recognized, depending mainly on the emphasis placed on chro- 
mosome number. Love (1944b), maintaining that “polyploidy alone seems 
to catapult a species into being,” has recognized four species: Rumex 
angiocarpus Mutb., 2n = 14; R. tenuifolius (Wallr.) A. Love, 2n = 28; 
R. Acetosella L., sensu sieteto: 2n = 42; and the arctic R. graminifolius 
Rudolph ex Lamb., 2” = 56. The morphological distinctions between 
these are few, mostly quantitative, and tend to disappear when popula- 
tions are studied over the entire range. Hexaploids (2n = 42) with the 
character of R. angiocarpus (tepals adnate to the fruit) have recently 
been found in populations from Europe, Canada, and Australia (Johnson 
& Briggs, p. 166). This complex, including Eurasian weeds of nearly 
cosmopolitan distribution, is represented in our area by diploid and 
hexaploid plants. Sex chromosomes are present, and the sex-determining 
mechanism is thought to be of the X/Y type. Rumex Acetosella is 
generally considered an indicator of acid, worn-out soils, but Artist, finding 
that the species grows on soils of pH 4.5—8.5, believes its distribution 1s 
probably dependent on a combination of several ecological factors, rather 
than on pH alone. 

Pollination in Rumex is almost exclusively anemophilous, although in- 
sects occasionally are attracted by the red fruiting inflorescences. The 
fimbriate stigmata are well adapted to receiving air-borne pollen. Rumex 
crispus and R. obtusifolius are distinctly proterandrous; several other 
species are reportedly self-pollinated. Experimental crosses between sub- 
genera have been unsuccessful. 

Floral structure in Rumex is believed to have been derived by reduction 
from the basic three-merous type possessed by the closely related Rheum. 
Internal vascular bundles and internal phloem have been described from 
several species of Rumex, including R. crispus, R. Patientia, and R. conglo- 
meratus. The perennial species without internal bundles are considered 
the oldest members of the genus 

The genus is of little economic importance. The leaves of some species 
are eaten as salad greens, the oxalic acid content imparting a slightly sour 
taste. Roots of Rumex hymenosepalus Torr., canaigre, contain up to 30% 
tannin and have been suggested as a commercial source of tannin. Some 
weedy species, such as R. crispus, are pests in cultivated areas, but can be 
controlled by cutting away the taproot to three inches below the soil 
surface, since regenerative capacity has been found lacking in the rest of 
the taproot (Healy).

Annual or perennial herbs, shrubs, or twining vines of diverse, com- 
monly moist habitats, often occurring as tenacious weeds in disturbed 
areas. Plants glabrous or pubescent; stems erect or prostrate, simple or 
branched, unarmed or with short recurved spines, the nodes often con- 
spicuously swollen; ocreae completely or partly surrounding the nodes, 
cylindrical, membranaceous or scarious, often becoming hyaline with age, 
the distal margin entire, shredded, or bearing 1 to many short awns. 
Leaves basal and/or cauline, membranaceous [to + fleshy], entire [rarely

and gonu, knee, the swollen nodes producing the appearance of jointed 
stems.) — KNOTWEED, SMARTWEED. 


A highly variable and taxonomically difficult genus of about 150 species, 
nearly world wide in distribution and composed of several natural species- 
groups, the taxonomic ranks of which are much in dispute. In recent years 
data from cytology, palynology, floral anatomy, and chemistry have been 
used in an attempt to determine the relationships of the taxa and to 
devise a more natural classification. Unfortunately, emphasis often has 
been placed on one technique, without regard for existing information 
from other studies, thus leading to conflicting classifications. There is 
a need for correlation and careful weighing of all data in future studies 
of Polygonum, sensu lato. 

The system followed here is, in general, modified from those of Steward, 
Steyermark, and Gleason. The infrageneric divisions, being based almost 
solely on variable vegetative characters, are considered sections of the 
genus. Thus defined, Polygonum is divided into eight sections, five of 
which occur in our area. Section Tovara, distinguished from the rest of 
Polygonum mainly by its persistent, indurated, hooked styles, is considered 
by some taxonomists to be worthy of generic rank. However, to establish 
a genus in this family on the basis of a single character, even a floral 
one, is out of keeping with the magnitude of differences upon which the 
other genera of Polygonaceae are based. Section TINIARIA is considered 
to include sect. PLEUROPTERUS, since morphological distinctions between 
the two, though present in the species of our area, are lacking in several 
Asiatic species (e.g., P. baldschuanicum Regel, a woody vine with 
capitate stigmata but a much-branched paniculate inflorescence). Identical 
pollen morphology (see Hedberg), as well as chemical similarities (Jar- 
etzky), support this union. Fagopyrum Mill., which differs from Poly- 
gonum in having nonaccrescent tepals, the embryo embedded in the endo- 
sperm, cotyledons rolled around the radicle, and more or less corymbiform 
inflorescences, is maintained as a distinct genus. 

The pollen of Polygonum is of interest because of its unusual diversity ; 
sectional limits within the genus are marked in several cases by distinct 


spermae. In P. Persicaria, for example, the archesporial cell acts directly 
as the pollen mother-cell, dividing to form four microspores in each locule. 
Rarely it divides to form two pollen mother-cells, resulting in eight pollen 
grains. In P. lapathifolium and P. sagittatum there are eight pollen grains 
in each locule, and in P. aviculare, P. Convolvulus, and P. orientale, 
thirty-two. Other species have several pollen mother-cells, and the number 
of pollen grains may be 64, 128, or 256. Species with porate pollen have 
fewer grains per locule than those with colporate pollen. The number of 
pollen grains does not characterize sections. 


1965] GRAHAM & WOOD, GENERA OF POLYGONACEAE 107 


Numerous chromosome counts have been made, but, unfortunately, 
many are unreliable due to questionable identifications and lack of voucher 
specimens. On the basis of all reported counts there seems to be no corre- 
lation between chromosome numbers and recognized sectional limits, wide 
ranges being found in each section. 

Section Poryconum (§ Polygonum DC., § Avicularia Meissn., Poly- 
gonum L., sensu stricto; including Duravia (S. Wats.) Greene) is com- 
prised of generally prostrate, much-branched annuals, with small leaves 
usually less than 2 cm. long and articulated at the base with the stem 
and flowers in axillary clusters. The pollen is spheroid-prolate, 3- or 4- 
colporate with furrows 4-44 the length of the polar axis, elliptic pores, 
and a smooth or granulate exine. Chromosome numbers of 2 = 20, 22, 
24, 40, 60, and 66 have been reported. Several widely distributed species 
of the section are present in our area, including the polymorphic P. 
aviculare L. (P. neglectum Bess., P. buxiforme Small), 2n = 20, 22, 40, 
60; the coastal American endemic P. glaucum Nutt., 2m = 20, 40; P. 
erectum L., 2n = 40; and P. tenue Michx., 2n = 20. Equally widespread 
in the United States, but of more restricted occurrence in the Southeast 
(mainly in Louisiana, Arkansas, and Tennessee), are P. ramosissimum 
Michx., 2n = 20; P. prolificum (Small) Robins., 21 = 60; and P. cam- 
porum ‘Meissen: The Asiatic P. argyrocoleon Steud. ex Kuntze has been 
collected as a waif on the outer banks of North Carolina. 

The species of sect. PocycoNumM reportedly are inbreeding, the flowers 
being self-pollinated and perhaps also cleistogamous. In recent work on 
P. aviculare and related species, Styles has suggested that both hybridiza- 
tion and apomixis are rare, the extreme variability in morphology resulting 
from the influence of seasonal changes and of environmental factors in 
general. 

Section Prrsicarta (Mill.) DC.* (Persicaria Mill.) includes plants 
of low, wet habitats and waste ground, with flowers in axillary or terminal 
spikes or racemes. The leaves are mainly elliptic to lanceolate and 
cauline, the tepals are neither keeled nor winged, and the branched stems 
are glabrous or pubescent, without recurved prickles. The pollen is 
spheroid, polyporate, with scattered circular pores and a reticulate exine. 
Reported chromosome numbers include 2” = 20, 22, 24, 40, 44, 60, and 
66. The section is the largest of the genus, with about 100 species. Of 
the 14 species in the Southeast, at least five are introductions from Europe 
or Asia: Polygonum lapathifolium L. (Persicaria lapathifolia (L.) S. F. 
Gray), 2n = 22; P. Persicaria L. (Pers. Persicaria (L.) Small), 2n = 40, 
44; P. Hydropiper L. (Pers. Hydropiper (L.) Opiz), 2n = 20, 22; P. caes- 
pitosum var. longisetum (De Bruyn) Steward; and P. orientale L. (Pers. 
orientalis (L.) Spach), 2" = 22, 24. The last two occur only in the 
northern part of our area, while the other three are widespread. Species

indigenous in our area are the variable, often aquatic P. coccineum Muhl. 
(Pers. Muhlenbergii (S. Wats.) Small); P. densiflorum Meissn. (Pers. 
portoricensis (Bert.) Small) and P. hirsutum Walt. (Pers. hirsuta (Walt.) 
Small), of the Atlantic coastal plain; and three highly variable species, 
P. pensylvanicum L. (Pers. pensylvanica (L.) Small), P. hydropiperoides 
Michx. (Pers. opelousana (Riddell) Small, Pers. setaceum (Baldwin) 
Small), and P. punctatum Ell. (Pers. punctata (Ell.) Small, P. robustius 
(Small) Fern.). Polygonum bicorne Raf. (Pers. longistyla (Small) Small) 
extends from the west into Louisiana, Arkansas, and Mississippi. Poly- 
gonum mississippiense Stanford (Pers. mississippiensis (Stanford) Small) 
has been described from Mississippi and Persicaria paludicola Small, 1933 
(not Pers. paludicola (Makino) Nakai, 1926), from the Everglades, 
Florida. The northeastern Polygonum Careyi (Pers. Careyi (Olney) 
Greene), although included in Small’s Manual, does not appear to extend 
southward into our area. 

A number of species in sect. PerstcartA have both terrestrial and 
aquatic forms (sometimes remarkably unlike) which can be changed from 
one to the other by merely changing the habitat. Such amphibious species 
are often sterile, spreading by means of rhizomes. Cleistogamy is re- 
ported in the section, and a tendency in the flowers toward separation 
of the sexes is apparent in some species, e.g., P. hydropiperoides. Several 
putative hybrids have been recorded between species of sect. PERSICARIA, 
especially in Europe (for a list of hybrids see G. Hegi, Illus. Fl. Mittel- 
Europa, ed. 2. 3: 396-400. 1958), but almost no controlled experimental 
studies have been made. Careful biometrical, ecological, and cytological 
studies are needed for a better understanding of the species limits in this, 
as in the other sections of Polygonum. 

Section EcHINOcAULON Meissn. (Tracaulon Raf.) is closely related 
to and at times has been combined with sect. Persicarta, from which it 
differs mainly in the sagittate or hastate leaves, reflexed prickles on the 
angles of the stem, and reclining, creeping, or climbing habit. The 
pollen is indistinguishable from that of sect. PersicArtA. Chromosome 
numbers of 2” = 20, 22, 24, 40, 44, 60, and 66 have been reported for 
the section. Two species, P. sagittatum L. (Tracaulon sagittatum (L.) 
Small), with sagittate leaves, and P. arifolium (T. arifolium (L.) Raf.), 
with hastate leaves, occur in tidal marshes and other wet places in our 
area. The Brazilian P. Meisnerianum Cham. & Schlecht. var. Beyrich- 
ianum Meissn., easily recognized by its cordate, narrowly lanceolate leaves 
and dichotomously branched inflorescence with glandular hairs, was col- 
lected, probably as a waif, along the Tchefuncta (Chefuncte) River, St. 
Tammany Parish, Louisiana, in the late 1800’s. 

Section Tovara (Adans.) Benth. & Hook.* (Antenoron Raf.®), com- 


‘Torrey (Fl. State N. Y. 2: 151. 1843), apparently, was the first to use Tovara 
as an infrageneric category of Polygonum, but without clear indication of rank. 
The first certain use of Tovara as - section of Polygonum appears to be that of 
Bentham & Hooker (Gen. Pl. 3: 98. 1880 

°If sect. Tovara is recognized at ‘the generic level, the name Tovara Adans. (Fam.

prised of one to three species disjunctly distributed in eastern America 
and eastern Asia, is distinguished by an elongate spikelike inflorescence, 
a 4-parted floral tube, and a persistent style, 2-parted to the base with 
recurved, hooked tips, which in fruit becomes very rigid and bent 
obliquely downward. According to Hedberg, the pollen is spheroid and 12- 
porate, with oblong pores arranged as though along the 12 edges of a 
cube; the exine is finely reticulate. 

The eastern American Polygonum virginianum L. var. virginianum 
(Antenoron virginianum (L.) Roberty & Vautier, Tovara virginiana 
(L.) Raf.) is widely distributed in shady bottom lands and thickets, 
from Quebec to northern Florida, west to eastern Texas and Minnesota, 
with disjunct populations in central Mexico (Hidalgo and Puebla). A 
glabrous variety, P. virginianum var. glaberrimum (Fern.) Steyerm., was 
described from our southeastern coastal states. The eastern Asiatic 
members of this section have been considered as either two distinct 
species (P. filiforme Thunb. and P. apoénse Elmer) or three varieties of 
P. virginianum, depending on the emphasis placed on density of pubes- 
cence, shape and size of leaves, shape of base of leaves, and color of 
tepals. Polygonum virginianum var. filiforme (Thunb.) Nakai, dis- 
tributed from southern Korea and Japan to southwestern China, has a 
reported chromosome number of 2” = 44. 

The dispersal mechanism of fruits in this group is unique in the family. 
During maturation of the fruit a separation layer forms across the pedicel, 
leaving only the vascular cylinder intact. When the fruits are mature, 
disturbance of the plant causes the vascular cylinder to break and the 
fruits to be catapulted forcibly as much as three or four meters. The 
origin of the catapulting force has not been satisfactorily explained in 
modern physiological terms (cf. Reed & Smoot). In addition to being 
thrown from the parent plant, the fruits, with their persistent hooked 
styles, may catch in the coats of animals, becoming dispersed over even 
greater areas. 

Section TrnrariaA Meissn. (including Reynoutria Houtt., 1777; Bilder- 
dykia Dumort., 1827; Tiniaria (Meissn.) Webb & Mogq., 1846; and 
Pleuropterus Turcz., 1848) is comprised of annual or perennial trailing 
or erect plants with axillary or terminal spikes or panicles. The tepals 
are keeled or winged, the stigmata capitate or fimbriate, and the pollen 
similar to that of sect. PotycoNum, but with furrows generally more 
than +, the length of the polar axis and a smooth to finely reticulate exine. 
Chromosome numbers of 2” = 20, 22, 40, 44, and ca. 88 have been re- 
ported for the section. 

Three species occur in our area. Polygonum Convolvulus L. (Bilderdy- 
Pl. -2: 276. 4763) cannot be used, since it has been rejected in favor of a later 
homonym, Tovaria Ruiz & Pav. (Prodr. 49. 1794; see Int. Code Bot. Nomencl. 263. 
1961), of the Tovinibtins or Cruciferae. The later name is an orthographic variant 
of the peers both having been designated in honor of a 16th century Spa 
physicia Simon a Tovar. "Female is replaced by the next oldest legitimate generic 
name, pri ies Raf. (Florula Ludov. 28. 1817; type species: A. racemosum 
Raf. = A. virginianum (L.) — & Vautier).

kia Convolvulus (L.) Dumort.), 2” = 20 and 40; P. scandens L. var. 
scandens (B. scandens (L.) Greene); and P. scandens var. cristatum 
(Engelm. & Gray) Gleason (B. cristata (Engelm. & Gray) Greene and 
B. dumetorum sensu Small), 2m = 20, are widespread in the Southeast 
and beyond. Polygonum cilinode Michx. (B. cilinodis (Michx.) Greene), 
of the northeastern United States, reaches its southern limit in Tennessee 
and North Carolina. In addition, the Japanese P. cuspidatum Sieb. & 
Zucc. (Pleuropterus Zuccarinii Small, Reynoutria japonica Houtt.), 2n = 
4 and ca, 88, and P. sachalinense F. Schmidt ex Maxim. (Reynoutria 
sachalinensis (Maxim.) Nakai), flowering bamboo, are often cultivated for 
their vigorous erect growth and showy panicles of flowers. Both species 
persist after cultivation and are very difficult to eradicate due to an ex- 
tensive, spreading rhizome system. In the Northeast, escapes are becom- 
ing obnoxious weeds. Both species have been collected in Tennessee and 
North Carolina and may be expected elsewhere in our area in the future, 
if not controlled. 

Extrafloral nectaries are found in several species of sect. TrNTARIA (€.2-; 
P. Convolvulus and P. sachalinense). They consist of a circular to oval 
depression at the base of the petiole on the abaxial side containing multi- 
cellular, short-stalked, glandular trichomes. Fully developed before the 
leaf unfolds, the nectaries are thought to function as hydathodes, pro- 
viding a release for excess turgidity developed during formation of the leaf.

Heather-like, subherbaceous annuals or suffrutescent perennials, mainly 
of sand hills, scrublands, and waste places. Branches many, erect, adnate 
to the parent stem for approximately half the length of the internode. 
Leaves alternate, narrowly linear to spathulate, caducous or persistent, 
sessile, articulated with and appearing to arise from the free upper edge 
of the membranaceous, cylindrical ocrea. Inflorescence racemose, terminal 
on primary and lateral branches, the flowers solitary in the axils of im- 
bricated ocreolae and slightly to well exserted from them; ocreolae uni- 
laterally flared to an acute or acuminate apex, the margin entire or bear- 
ing several short to long, bristle-like hairs. Flowers bisexual or function- 
ally unisexual (the plants dioecious, gynodioecious, or gynomonoecious) ; 
pedicel broader and longer than the stipe and subtended by 2 lanceolate, 
keeled, scarious bractlets, or bractlets wanting. Tepals 5, slightly fused, 
forming a short floral tube, erect (the outer tepals occasionally tardily 
reflexed), in 2 whorls of 2 outer and 3 inner ones, or (in subg. Thysanella) 


included, alike (subg. T/ysanella) or the inner whorl of 3 dilated near the 
base forming 2 lateral nectariferous teeth (subg. Polygonella); anthers 
versatile; pollen prolate, 12-40, long, tricolporate, the pores equatorially 
arranged, the furrows longitudinally elongated, the exine reticulate. Gynoe- 
cium 3-carpellate; stigmata 3, punctate; styles 3, filiform, free to the 
base; ovary 3-angled, slightly stalked. Fruit a shiny yellow to brown or 
gray pyramidal achene. Embryo straight, in one of the angles of the 
seed; cotyledons oblong, thick and fleshy; radicle equalling or exceeding

Indigenous to the eastern United States, with two subgenera and nine 
species, all but Polygonella Parksii Cory (endemic to Atacosa and Wilson 
counties, Texas) occurring in the Southeast. 

Subgenus THysaNeLta (A. Gray) Horton® (Thysanella A. Gray, 
Polygonella § Thysanella (Gray) Roberty & Vautier) has inner tepals 
fimbriate, filaments alike, and pedicels subtended by bractlets within the 
ocreolae. It consists of Polygonella fimbriata (Ell.) Horton var. fimbriata 
(T. fimbriata (Ell.) A. Gray), of Florida, Georgia, and Alabama, and 
var. robusta (Small) Horton (T. robusta ‘Small), 2n = 32, endemic to 
Florida. 

Subgenus PoLyGonELLa (§ Delopyrum (Small) Roberty & Vautier, § 
Dentoceras (Small) Roberty & Vautier), with inner tepals entire, the 
inner whorl of filaments dilated near the base, and pedicels not subtended 
by bracteoles within the ocreolae, composes the remainder of the genus. 
The species are distinguished by such characters as habit, type of margin 
on the ocreolae, number of ocreolae in a raceme, shape and size of leaves, 
and color and position of tepals during flowering and fruiting. 

The procumbent, mat-forming Polygonella myriophylla (Small) Horton 
(Dentoceras myriophylla Small) is endemic to the southern part of the 
Florida lake region. Polygonella ciliata Meissn. var. ciliata and var. basi- 
ramia (Small) Horton (Delopyrum ciliatum (Meissn.) Small and D. basi- 
ramia Small), both 2m = 22, are also restricted to Florida. Polygonella 
macrophylla Small, 2n = 28, occurs on the Gulf Coast of Alabama and 
northern Florida. More widespread are P. gracilis (Nutt.) Meissn. (De- 
lopyrum gracile (Nutt.) Small, Delopyrum filiforme Small), 2n = 22, 24; 
P. polygama (Vent.) Engelm. & Gray (P. brachystachya Meissn., P. 
Croomii Chapm.), 2m = 28; and P. americana (Fisch. & Mey.) Small. 
The first two are species of the Coastal Plain; the latter is generally pied- 
montane, occurring sporadically from South Carolina to central New 
Mexico. Polygonella articulata (L.) Meissn. (Delopyrum articulatum 
(L.) Small), 22 = 32, is the only species of the genus in the northeastern 
United States, reaching its southern limit in northeastern North Carolina. 
It is regarded as the most primitive species of Polygonella by: Horton, 
who also believes that the modern species of the genus evolved in Florida 
from an ancestral stock forced southward by Pleistocene glaciations. 

Internodal branching characteristic of Polygonella is lacking in the 
rest of the family. The wood anatomy is characterized by a lack of 
parenchyma in annuals and by axile xylem parenchyma in perennials. 
Starch is stored in the xylem in an unusual cell type which resembles a

fiber in shape and pitting, but is nucleate and living at maturity. The 
floral anatomy is, by reduction, the simplest in the family (Vautier). 
Each tepal has a single trace which connects with the main vascular 
supply; the other floral parts are supplied by single free traces which 
end in the floral tube. No anatomical evidence of a double trace to the 
fused inner and outer tepal can be seen in this genus. Reported chromo- 
some numbers form an aneuploid series (2m = 22, 24, 28, 32).

Dioecious shrubs or trees [vines] of warm sandy coasts and hammocks; 
nodes often swollen or geniculate. Leaves evergreen [or deciduous}, 
thick and leathery [or membranaceous], alternate, variable in size and 
shape, ours reniform to orbicular or oblong to elliptic with apex obtuse 
and base cordate to acute, the surfaces minutely punctate [or the upper 
surface pitted and lower with superficial or sunken glands]; petioles short, 
attached to the stem near the base of [or well above] the partly deciduous 
tubular ocrea. Inflorescence a many- to few-flowered raceme [spike or 
panicle], less than to exceeding the leaves, terminal on primary and lateral 
branches. Flowers regular, greenish or yellowish white, unisexual or 
functionally so, campanulate, with a short floral tube, the stipe mostly 
equal to or shorter than the pedicel, the young buds completely covered 
by the ocreola which ruptures as they mature; pedicels [less than to] 
exceeding the length of the ocreola. Staminate flowers in 2—5-flowered, 
bracteate fascicles at the nodes, each flower subtended and surrounded 
by the persistent ocreola which incloses the adjacent flower and its ocreola, 
additional ocreolae of aborted flowers occasionally also present, the fila- 
ments long, exserted, the styles short, included. Carpellate flowers soli-

An indigenous tropical and subtropical American genus of about 170 
species and one of the few tropical genera in the family. The greatest 
number of species (about 85) occurs in South America (about 44 in 
Brazil); two reach their northern limit in peninsular Florida. The sea 
grape, Coccoloba Uvifera, 2n = 132, a characteristic shrub or small 
tree of warm, sandy shores from Florida to northern Argentina, is im- 
mediately recognizable by its large orbicular to reniform leaves and the 
dense clusters of sweet-acid, rose-purple fruits (nearly black when fully 
mature). The pigeon plum, C. diversifolia Jacq. (C. laurifolia Jacq., C. 
floridana Meissn.), 2n = 22, a tree to about 20 m. tall, with generally 
smaller, oblong to elliptic leaves and nearly black fruits, inhabits ham- 
mocks and scrublands in Florida, the Bahamas, the Greater Antilles, and 
Antigua. Both range along the east coast of Florida north approximately 
to Merritt Island; on the west coast C. Uvifera occurs at least as far 
north as Manatee County, but C. diversifolia is restricted to the southern 
counties. Hybrids of the two are known from Everglades National Park, 
Florida, and Prov. Pinar del Rio, Cuba. Coccoloba Uvifera also hybridizes 
with several other species elsewhere in its range. 

The taxonomy of the genus presents numerous difficulties. Many species 
have at least two names, one based on a staminate, the other on a carpel- 
late plant, the unisexual condition having been discovered only recently 
(cf. Howard, 1949). Morphologically, the flowers vary little among 
species, while vegetative characters which, for lack of floral differences, 
must be used in classification, are extremely variable. In collecting Cocco-

An earlier count ae 2m = ca. 80 for C occoloba Uvifera (Edman, re Horti Berg. 
9: 270. 1929) is open to question, for it is possible that this was obtained from either 
hybrid or apomictic material of C. Uvifera. Since the name C. diversifolia has been 
applied incorrectly to several different species, Jaretzky’s count of 2 = ca. 200 
(Jahrb. Wiss. Bot. 69: 441. 1928) may have been obtained from another species. 
Apparently both reports are undocumented by herbarium specimens

loba care should be taken to represent the diversity of growth habit and 
leaf variability within the population. Adventitious shoots, which tend 
to have longer internodes and larger leaves than the normal stems, should 
also be included. Since the fruit of many species changes in shape as it 
matures, comparisons of size and shape can be made only with fully 
mature fruits 

A successful ornamental, Coccoloba Uvifera is planted along seasides 
in warmer regions of the world for its hardiness and attractive fruiting 
racemes and evergreen foliage. It has been reported in cultivation since 
1690 and has become naturalized in several places in southeastern Asia 
and on some Pacific islands. Two variegated leaf forms are propagated. 
It is successful also as a pot plant, requiring little care except pruning. 
Jelly is sometimes made from the fruit. Coccoloba diversifolia, with 
bronze-colored juvenile leaves, is planted as a street tree in southernmost 
Florida. Both species are considered good honey plants, and birds feed 
on the fleshy fruits. Little work has been done on the biology of the genus, 
although hybridization apparently is frequent, and apomixis is suspected. 
Fossil leaves of Coccoloba are known from the Paleocene or Eocene of 
Alaska and also have been reported from Alabama, Mississippi, Texas, 
Arkansas, Louisiana, Tennessee, Kentucky, and Wyoming.

localities in Florida. Its natural range is described as Baja California and 
Chihuahua, south to Oaxaca, Mexico. In Florida the plant blooms con- 
tinuously from early spring to late fall and may reach a height of 10 m., 
climbing by means of tendrils. Abundant viable seeds and edible tubers 
are produced, from which new plants sprout in the spring. The genus 
is insect pollinated, as the brightly colored tepals and copious nectar 
indicate. A white-flowered form (= A. flavescens?) is occasionally culti- 
vated.

LETTERS FROM CHARLES SPRAGUE SARGENT TO 
REGINALD SOMERS COCKS, 1908-1926 * 
Edited by JosEpH EWAN 


82 
May 6, 1915. 

You sent us leaves of Malus from Sardis under three numbers — 1, 2 
and 3. These appear to us, however, to be all the same thing and until I 
went to Selma I thought they might be a form of Malus ioensis, but I col- 
lected flowers on the road between Selma and Sardis which look very much 
like the flowers of Malus platycarpa. Now what we want is the fruit to 
make the determination certain. I suppose you can manage that this sum- 
mer. I was surprised to find Persea palustris so common about Sardis as I 
did not know it ever got so far into the interior. 

I had a letter from Palmer this morning in which he said things were 
coming out very rapidly and he thought Tilia would be in bloom in a 
week. I hope therefore you will bear in mind the collections of flowers at 
Lake Charles and Avery Island. Palmer says there are more different kinds 
of trees and shrubs about Natchitoches than any place he has yet visited, 
although Crataegus is not represented there by many groups. 

How about the name for our Lake Charles Carya? I want to write the 
description and am depending on you for a very fancy and first-class 
name. 

P.S. — There is a man here now preparing a monograph of Smilax, so 
if you have any doubtful specimens we had best see them. Your Smilax 
91 from Wakefield, June 1907, is Smilax lanceolata. 


83 
May 12, 1915. 
What is the Tilia situation? Of the three Lake Charles species we have 
flowers only of #2 and no fruit of 1, 2 and 3. Of the Sardis species which 
grows on the river bluff, your +6 of 1914, we have flowers and fruit. Of 
your other species (#41110) we have specimens only in very young bud, 
but a specimen of yours (no date and no number) is in flower; the label 
says “the neighborhood of Selma”. This is the tree I found at Selma but 
did not see at Sardis where I suppose you did not see it. I hope you will 
be able to manage the fruit of this second species this summer. It cer- 
tainly ought to be pretty fully grown before you return to New Orleans. 
Pretty bad times these but there is no use thinking about them when 
there are trees to think of.

May 21, 1915. 

I congratulate you on having found such a fine tree as Magnolia acu- 
minata in Louisiana. I do not think it is surprising that it should be there 
but rather that it should have been overlooked so long. Please tell me the 
exact place where you found it, town if possible, so that I can enter it 
properly in my Manual. 

This does not seem such a remarkable discovery as the finding by Harbi- 
son of Magnolia in northeastern Mississippi. He is finding a great many 
interesting things in that state and it would not surprise me if Carya pal- 
lida reaches eastern Louisiana as he finds it so abundant in western central 
Mississippi. You ought to make a special hunt for this in West Feliciana. 

Carya callicoma I think sounds good and I am much obliged to you for 
the suggestion. 


85 
June 2, 1915. 

I have written out the description of C[arya] callicoma. Your #15 
from Natchitoches, with very young leaves, looks as if it might be this 
species. I do not suppose you remember much about it. 

Is it possible that the Winnfield trees “in dry woods”, that is near the 
quarry, with young leaves pale tomentose below, can also be callicoma? 
I think Winnfield needs more investigation as to its Hickories. 

Your #1 Lake Charles, October 1913, is of course the same as your 
tree from the man’s yard, and undoubtedly C. arkansana. There is fruit 
which probably belongs to this species collected “‘near English Bayou” 
where we did not see C. arkansana. 

#11, 12 and 16 Natchitoches are C. arkansana, and #3 from Grand 
Ecore is probably the same. 

I hope soon to hear from you about Tiélias. 


86 
June 14, 1915. 
I am glad to get your letter of the 10th of June which has arrived just 
as I was going to write to tell you that among some specimens of Tilia 
sent by Palmer are three numbers from Lake Charles and all apparently 
our +1. He seems to have missed the other two numbers, at least there is 
no trace of any pubescence whatever on these specimens. They were 
gathered too soon but among the lot there are one or two open flowers. I 
very much hope therefore you have been to Lake Charles and have got 
the flowers of our three numbers. I should judge that you might have 
been too early at Avery Island as I have received from a young lady there 
specimens of what she calls the smooth and rough-barked trees. The 
flowers, however, will answer our purpose after a fashion. 
Is it possible that Liriodendron does not reach Louisiana? I have no 
record of it there and no specimen. 


124 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Can you tell me the range of Quercus velutina in Louisiana? While at 
Sardis you will look out, of course, for that peculiar Quercus coccinea with 
the deep cups. It will be interesting to know if this is a common form or 
only the peculiarity of an individual tree. I do not know what to say about 
that little Post Oak about Selma in which Harbison is so much interested. 
The leaves are very tomentose on the lower surface but I do not see that, 
except in habit, the shrub differs from the large trees in Selma. You have, 
I hope, the memorandum of the two Plums we found in flower near your 
place and south of Selma. 

As I think I told you, I am trying to arrange the Hickories largely on 
the absence or presence of yellow scales on the leaves and on the involucre 
of the pistillate flower and fruit. I had supposed that these yellow scales 
did not occur on the pistillate flowers and young fruit of Carya alba until 
the other day when I received from Harbison specimens collected in Mis- 
sissippi of what otherwise looked like Carya alba, but the young fruit was 
thickly covered with yellow scales. Such scales certainly do not occur on 
our tree as it grows here, and it is possible that the northern and southern 
trees ought to be separated. All this is preliminary to a request that you 
will look at Carya alba in the Selma region and see how the young fruit 
looks, and possibly dry me a few specimens, especially if you find the 
yellow scales. 

Instead of going to North Carolina why don’t you come to Brookline 
and do some work on the synonymy and bibliography of your Flora? 


87 
June 23, 1915. 

I never received a more interesting package of plants from you than the 
one which arrived this morning — very many thanks. 

Quercus 800 is surely Small’s Quercus austrina which we have been 
hunting for so long and is evidently a good species. Would n’t it be pos- 
sible to get fruiting specimens? 

802, Quercus coccinea. Is this the tree on the bank with the peculiar 
cups I wrote you about? 

804, Quercus nigra. This is a distinct form with thicker leaves which 
are usually three-lobed at the apex. I saw a good deal of it between Selma 
and Sardis, and I think it ought to have a varietal name. 

Tilia 788, Sardis, with leaves pale and glabrous below and prominent 
axillary tufts, seems to equal 2528, West Feliciana, and probably our 2 of 
Lake Charles. This I think is a common and widely distributed species in 
the southwest. 

Tilia 784 and 786, leaves green and glabrous below, axillary tufts very 
small, looks like 2534 of Lake Charles. 

780, 782, 790 and 792, the Tilia with leaves white pubescent below. 

It would seem as if there were three and not two Tilias in the Selma- 
Sardis region as I had supposed. I only saw two last spring. 

Acer 2520 seems to be a form of the Sugar Maple which is common in 
southern Georgia and in Mississippi. The leaves are paler on the lower 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 125 


surface but I can see no other difference. We have never had flowers or 
fruit of this. 

Quercus 2524, ee 

Quercus 2526, Q. a 

Tilia 2530, HEL, nm Charles,” on English Bayou at Miller Place. 
This has leaves densely pubescent below, but our #1 from Miller Place 
with checkered bark, collected April 12th, is perfectly glabrous. 

Tilia 2536 is our #2 of April last. 

Tilia 2534, bark like a Persim[m]on, is our #1, although you say #2? 

I do not think we collected your 2530 at all. The pubescence is more 
rusty than that on the leaves of our #3. This new Lake Charles tree may 
be one of the Avery Island species. Did you find it on the Miller place? 

You do not appear to have collected this time our #3 which has leaves 
white-pubescent below. The trees near the schoolhouse in West Lake 
Charles and the tree by the river bank in Lake Charles are our #3. This 
seems to be a common species and no doubt Palmer has the flowers. 

Let me hear soon what else you are finding of interest at Sardis which 
seems to be an inexhaustible field. 


88 

June 28, 1915. 
The Ptelea which we collected at Lake Charles in March 1911 looks 
exactly like the Ptelea rhombifolia of Heller and I think should be referred 
to that species, at least until we know more about the different forms of 
this troublesome genus. From eastern Louisiana I have one specimen of 
P. trifoliata collected by you but no other Ptelea at all from Louisiana. 
Have n’t you met with the genus in other places in that state, and how 
does it happen that Selma and Sardis, which contain almost every other 
known plant, cannot boast of a Ptelea, at least there is nothing from that 

region in our herbarium? 


89 

July 2, 1915. 

Very many thanks for the fruit of Carya alba which tells me just what 

I wanted to know. It is surprising that these yellow scales on the fruit 
of this species have always been overlooked. Perhaps, however, this is not 
more remarkable than that every American botanist has described the 
st of Epigaea repens as a dried capsule although it is really a fleshy 

erry. 


There is no one now in this country who knows so little about Tilias as 
I do, but I should think Palmer could look after the fruit of the Lake 
Charles species this autumn. As you have read in my last letter, there is 
what appears to be a fourth species there. Undoubtedly the West Feliciana 
species are the same as those which grow at Natchez and I do not think 
you need to worry much more about them. This leaves Avery Island from 
which we certainly ought to have good fruiting specimens. I wrote to the 


126 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


lady who sent the specimens the other day from there, asking her to send 
me a specimen of one of her numbers showing the young branches but I 
have had no answer from her. I have no more idea than you do when the 
fruit of these things ripen. 

The Scarlet Oak which I want you to look into is a single tree growing 
on the edge of the bluff, or rather a little way back from the edge. We 
went from your place to a store, the post-office of Sardis I think, and then 
took the road to the river. We got out at a negro cabin near the river, 
walked across a field, and then turned to the left and followed along the 
cliff for some distance. This particular Oak cannot be more than three 
hundred yards from where we reached the bluff. The remarkable thing 
about this tree is the much swollen scales of the cup. If this sort of Scarlet 
Oak is common in the Sardis region, then it ought to be made a variety of 
Quercus coccinea. 1 think perhaps I had best send you one of the fruits 
we picked up under the tree. As you know, Quercus rubra also grows on 
this bluff, and very far south of any station I have known for it before. 

How about the two Plum trees of which I wrote you? I hope you will 
follow them up, and also Quercus austrina. We should be glad to get 
specimens of any of the woody plants growing about Sardis which you may 
have time to make.

July 22, 1915. 
You have n’t said anything about having collected at the time of your 
last visit to Lake Charles fruiting specimens of that remarkable Ash tree 
with pendulous branches which we saw there. If you did not collect fruit 
I can ask Palmer to get it when he goes there this autumn. How early do 
you think the tree is likely to drop its fruit, and can you give any specific 
directions for finding the trees? We only saw one tree, as I remember, with 
fruit on it and that was hanging over a cottage close to the road. This of 
course was as we went down the lake (not towards the bayou) but I should 
not know what to tell Palmer in order to find this particular tree. 
Anything new in the tree line at Sardis, and have you given up the idea 
of coming north this summer? 


91 
July 23, 1915. 
How about the Slippery Elm, Ulmus fulva, in Louisiana? It is common 
from Missouri to Texas and it ought at least to be in western Louisiana, 
but I have no knowledge of it there. 


92 
July 29, 1915. 
A new tree for the Selma region is Carya carolinae-septentrionalis which 
Harbison collected there this spring. 
Why can’t you send me now a specimen of the White Oak near your 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 127 


place which we thought was Quercus austrina? I should like to see it in 
its present summer condition. It might be sent without drying I should 
think. 


93 
August 7, 1915. 

I have your letter and the package of specimens, for both of which many 
thanks. 

Acer 820 and 828 are A. saccharum. This form with leaves pale and 
pubescent below appears to be a rather common tree from southern Georgia 
and northern Florida to Mississippi. Acer 822 is A. floridanum. 

Carya carolinae-septentrionalis is right. I have already written you 
that Harbison had found it near Selma. 

Quercus 814 looks as if it might be a hybrid of Q. imbricaria. Do you 
know more than one tree? We ought to know more about it and get more 
material. 

Quercus 812 Sardis must be Q. Durandii. Is this the small tree on the 
left-hand side of the road going from your house towards Sardis and at 
the foot of a rather steep hill where our motor got stuck? This was the 
tree we took for Quercus austrina. Please answer this. If your 812 is not 
our little tree, where does it grow? Have you noticed on 812 that the 
leaves on the lower branches are very different from those on the upper 
part of the tree? 

Is your Quercus 800 the same as the 804 mentioned in your letter? 
800 looks as if it might be the mysterious Q. Aybrida of Chapman. 

The Tilia cultivated at Lake Charles is Tilia tomentosa from Hungary. 

I saw only two Lindens in the Selma-Sardis region but there are evi- 
dently three species, — Ist, the tree with leaves silvery pubescent below, 
your 780, 782, 790 and 792. 2nd, the tree with very coarsely serrate leaves, 
your 784 and 6 of July 1914. I did not find this tree and I do not know 
if the young leaves are all pubescent, and I am afraid that you do not. 
3rd, the tree with leaves not so coarsely serrate as #2, covered below with 
pale stellate hairs in April and in June entirely glabrous with the exception 
of the conspicuous axillary tufts. This is your 788. 786 is the same but 
without the tufts. This was the only Linden I saw on the bluffs of the 
river at Sardis but I saw plenty of #1 south of Selma. 

I think now, thanks to you, that we have complete material of these 
three Lindens. Can’t you induce your friends at Avery Island to collect 
good fruiting specimens of Lindens there? There are probably two species, 
one a tree with pubescent branchlets and rusty pubescent leaves which 
are very scabrate above, your #6 of October 1910. I do not know that 
we have either flowers or fruit of this. It seems similar to the tree from 
the coast of Georgia which has passed for T[ilia] pubescens, but I daresay 
it is not that species. Two, a tree with leaves pale pubescent below and 
also rough above. This is Miss MclIlhenny’s smooth-barked Linden and 
your specimen of May 24, 1914. Can this be the same as #1? The dif- 
ference in the time of year when the specimens were taken may account 


128 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


for the different color of the pubescence. Miss McIlhenny’s rough-barked 
Linden may be the same as #1 but the specimen is so poor that it does 
not tell much. 

Palmer is now in St. Louis arranging his collection and I am afraid can- 
not get off much before the first of September, but I shall write him to get 
back to Louisiana as soon as possible. The Florida and Alabama Oaks 
seem to be as puzzling or more puzzling than the Lindens. 

I wish you were here now for I am living all alone and we might get 
through a great deal of work together. 


94 
August 10, 1915. 

I have received from you a box of Plum fruit i no word as to what it 
is. I suppose I should hear from you on this subje 

Your Wakefield, West Feliciana “Tilia americana,” June 1907, is evi- 
dently the same as Selma #2, and the same as your specimen collected 
near Alexandria June 1905. 

I cannot quite follow you on the Lake Charles Tilia. Your #2532 with 
pubescent branchlets and leaves pubescent below agrees with our #3 of 
last spring, but your #1 from the Mills’ place (42530) has the same 
pubescence as your number 3 (2532) although the branchlets are gla- 
brous. Now unless there is a bad mixup on my part it is impossible that the 
tree in Mill’s yard which had perfectly glabrous leaves on April 12th 
should on May 21st have leaves densely pubescent below. 

I am writing Palmer today to get off as soon as possible and go first to 
Lake Charles for evidently there is no Linden at Natchitoches which does 
not also grow at Lake Charles. I hope you are hunting Oaks. 


95 
August 19, 1915. 

Many thanks for your two notes and the information they contain. I 
hope you will continue to watch the Oaks at Sardis. You have said noth- 
ing about that peculiar form of Quercus coccinea about which I wrote you. 

If the leaves of Tilias are going to change from glabrous to pubescent 
as they grow older I am afraid it will be hopeless to find characters by 
which they can be separated. 

Too bad about Avery Island for I suppose the weather won’t become 
cool there or mosquitos disappear until it is too late to collect Tilias. 

I hope the cotton crop is going to be a success. 


96 
August 21, 1915. 
I enclose a leaf of an Oak which Harbison found at Pleasant Hill, near 
Selma, and which may be an extreme form of Quercus Durandii. He found 
similar trees at other places near Selma, and I have asked him to write 
and give you as near as possible the locality of these trees in the hope that 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 129 


you will be willing to investigate them before you leave Alabama and 
obtain mature specimens. According to Harbison Pleasant Hill is a very 
interesting place, and possibly you may like to visit it. 


97 
August 23, 1915. 

Many thanks for yours of the 19th and for the Plums which have not 
yet arrived but which I suppose will be here tomorrow. It seems to me 
that this is about the worst of all the groups of our woody plants. 

We are sending you by express to Tulane a set of woody plants col- 
lected in Louisiana by Palmer this year, or rather nearly a full set for I 
understand he has been obliged to leave some of them behind him at St. 
Louis in his pursuit of Tilia fruit. I will arrange that the herbaceous plants 
be sent from St. Louis. 

I take no responsibility for Palmer’s names, and a few of them appear 
to be incorrect. Notice his Quercus 7473 with leaves only from Natchi- 
toches, which looks as if it might be Q. Durandii. His Quercus 7448 from 
Natchitoches seems to be the three-lobed form of Q. nigra common be- 
tween Selma and Sardis. It needs a varietal name. His Q. stellata var. 
Grand Ecore 7518 and Chopin 7978 we are much interested in here. The 
pubescence seems to be like that of the Post Oak in Selma. I do not know 
if I wrote you about this tree and the importance of collecting fruit of it 
this autumn, as well as the little dwarf Oak in sandy soil near Selma which 
is evidently a dwarf form of the larger tree. Palmer makes a point that 
the bark of his tree is scaly like that of the White Oak and not rough like 
the Post Oak. Is this true of the Selma tree? 

Palmer’s Quercus velutina 7443 is stellate-pubescent on the upper sur- 
face of the leaves. This sort of pubescence so far as I have seen never 
occurs on the leaves of the straight velutina but is conspicuous on the 
variety missouriensis of mine from Missouri and Arkansas. On the Mis- 
souri tree, however, the branches are much more tomentose than Palmer’s 
7443, but in Mississippi and Florida there is a velutina without tomentose 
branches but with stellate pubescence on the upper surface of the leaves 
at least early in the season. This may be another variety. It has not yet 
turned up in Alabama and I hope you will be able to look at the velutinas 
in your region and see if you can find any trees with such stellate pubes- 
cence. Harbison claims that the trees in Mississippi with the stellate 
pubescence do not have the orange colored inner bark. This is a fact, 
however, which needs further investigation. 


98 
October 20, 1915. 
Many thanks for your letter of October 15th. No, I have n’t been ill 
but away on several short journeys this autumn and my correspondence 
has fallen into a hopeless condition of neglect. I was on the point of 
writing you when I heard of the storm in Louisiana but did not get around 
to it. I hope you did not suffer personal inconvenience, but I am afraid 


130 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


many of our trees at Lake Charles were destroyed. I hope, however, the 
Hickories are all right. 

Have you been out this autumn with Palmer? He wrote me that you 
thought of doing so. I have n’t heard from him for some time and I fancy 
that he is now in eastern Texas or Oklahoma as he went early from Louis- 
iana. I am sorry to say that he found that many of the Lindens from 
which he collected in the spring were blown down early in the summer. 

Please let me hear from you soon. 


a9 
November 1, 1915. 

Many thanks for the collection of Oaks from the Selma district. The 
more I see of these Selma Oaks the less I know about them and this last 
collection of yours seems to me the worst lot I have seen. 

904 is Crataegus tomentosa. The other specimen of Crataegus in fruit 
I do not know. 

950. I do not know this Oak. Is it some form of the Water Oak? Do 
you remember the tree? 

954. Quercus velutina. 

972. Quercus austrina, if there is such a thing. 

962 I suppose is the dwarf form of the new Post Oak with scaly bark. 
As you know, this also grows at Natchitoches. 

934. Is this not the common Post Oak? It shows none of the pubes- 
cence which is so conspicuous on the under surface of the leaves of the 
new Post Oak. How is the bark of this 934? 

952, 968, 960 and 932 seem to be QO. Durandii. 

930. Is this Q. austrina again? 

938 looks as if it might be a hybrid of Q. imbricaria. It is unknown to 
me. 
956 is the new Post Oak. 

958 is nearly glabrous and I suppose is the common Post Oak. 

I am going to take up the Oak question seriously when Harbison’s col- 
lection of the past autumn arrives and try and come to some conclusion 
about some of these troublesome southern species, varieties or hybrids. It 
is rather curious that this scaly barked Post Oak grows at Selma and then 
not again until we get to Natchitoches. By the way, Palmer writes that 
he thinks he has found Gleditsia texana at Natchitoches. This would be 
a new tree for Louisiana. Apparently anything can be expected in the 
Natchitoches region. 

I hope you are all right.

November 12, 1915. 
We have been able to raise two new Chinese Citrus plants which may 
prove useful. The first of these, Citrus ichangensis,’® has fruit something 


° Burkill includes this in C. macroptera, as a race of thick-skinned shaddock-like 
Citrus. 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 131 


like a grapefruit although rather smaller. Some persons think that the 
fruit has even a better flavor than that of grapefruit but this of course is 
doubtful. The great point about it is that it is likely to be much hardier 
than the grapefruit or any other Citrus plant with edible fruit. The fact 
that our plants are raised from seeds gathered from wild plants growing 
in the mountains of western China suggests that the plants may be freer 
from disease than many of the long cultivated forms. The second plant is 
an Orange and still unnamed. It is said by Wilson to be the best of the 
tight-skinned Oranges of China. It is a low level plant in the Yangtse 
Valley but should prove hardier than the ordinary cultivated Orange. I 
could send you fifty or one hundred plants of each of these if you can use 
them to advantage among your friends in Louisiana. I think these trees 
should be introduced. Let me hear about this as soon as you conveniently 
can. 


101 
November 22, 1915. 

I have yours of the 20th and you may be sure we shall send you a set 
of Palmer’s plants as soon as they arrive. He is now working on them in 
St. Louis and I expect something from him very soon. 

It would certainly be remarkable if you have found M[agnolia] cor- 
data in Louisiana. As you know perhaps, it has recently been rediscov- 
ered in Georgia. If you have specimens of the leaves I should like to see 
them as they throw some light on the identity of the plant. 

We are arranging to send you two hundred and fifty of the Ichang 
Orange and two hundred and fifty of the Ichang Lemon for distribution 
among your friends in Louisiana. We can send more if you want them. 
The Arboretum will take the liberty of paying the express charges on the 
case to New Orleans as you ought not to be put to any expense in this 
matter. 


102 

December 7, 1915. 
The Citrus fruit started from here last night in two cases by express and 
I have no doubt will reach you in good condition. They have been in- 
spected and I do not think there can be anything the matter with them. 
Now if you can use more of these plants to advantage in Louisiana we 
can send them to you. I am anxious, of course, to get them as widely dis- 
tributed as possible. I advise you to try a few of Citrus ichangensis at 
your place in Alabama. This ought to prove, judging from the locality 
where the trees grow naturally, the hardiest of all the Citrus species with 
edible fruit. If you want more you better let me know soon before winter 

really sets in. 
Crataegus 964 from Sardis, 1915, is evidently C. tomentosa, although 
I have n’t seen the flowers, and the same as your 14 Sardis, 1914. These 
are the only Alabama specimens of this widely distributed tree we have 


132 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


and I have no other record of its extending into Alabama, so this is an- 
other tree the distribution of which you have greatly extended. 


103 
December 14, 1915. 
I have just been looking over the Louisiana specimens of Malus. 
Your Pineville specimen, our +1 west of Opelousas, the Crowley speci- 
mens and your specimens collected at Natchitoches April 15, 1911 and 
April 15, 1912, and Palmer’s Natchitoches 7252 we are placing with 
M{alus| ioensis var. Palmeri. This leaves now only our Malus 42 west 
of Opelousas, a tree thirty feet high with red-brown bark. This is cer- 
tainly something different. It may be an extreme form of M. angustifolia 
but I hardly think so. I had supposed you collected flowers but I do not 
find them, although you visited the tree the second time to collect fruit. 
The flowers if possible should be collected in the spring. 
I have just written Harbison that we have n’t got to the bottom yet of 
the Selma-Sardis species of Malus and I hope he will visit that locality 
again next spring. 


104 
December 16, 1915. 
In writing you yesterday I made a mistake, of course when I said we 
had referred your Pineville Malus to ioensis var. Palmeri. It is, of course, 
the type of ioensis creniserrata. 


105 
December 18, 1915. 

I am very glad indeed to hear that the Citrus plants reached you in 
good condition. We have plenty more of them and I shall be glad to send 
you another supply if you can use them to advantage. I do not suppose 
the Orange is going to prove of much value but the so-called Ichang 
Lemon I believe will turn out to be a plant of much economic value. 

Yes, I remember about the Crataegus from Louisiana and will get to 
it before long I hope. 

Ashe is a man who is apt to make a good deal of trouble and I suggest 
that you be cautious about sending him material. He has a way of not 
keeping specimens on which he makes species and then forgetting them 
himself. How about the Magnolia cordata? 


106 
December 22, 1915. 
We have no specimen of Quercus cinerea collected in Louisiana by you, 
and only one specimen in the state recently collected at Natchitoches by 
Palmer. Does not this tree occur in eastern Louisiana and have n't you 
seen it in other places in western Louisiana?

I have been looking over your Sardis specimens of Quercus. 

#800 with “bark like the White Oak” is what Harbison feels sure is 
Small’s Q. austrina, but the old fruit which you picked up from the ground 
with this specimen is probably Q. texana. The following are also austrina: 
804, 958, 956, 930, 950, 934, 902, 932. This seems to be a good species 
and to be widely distributed. You ought to find it in eastern Louisiana.

January 8, 1916. 
I have your note about Quercus austrina. I confess that without acorns 
I cannot tell austrina from Durandii with any degree of satisfaction. Ap- 
parently what we are calling austrina according to Harbison is sometimes 
a large tree, and the tree which he considers austrina certainly always has 
scaly bark. Small, as you know, is often rather vague in his descriptions. 
Probably there is a good deal more to learn about these trees. P.S.— Do 
you know anything about an Oak collected by you in St. Tammany, July 
1900, No. 6, and called by you Quercus tomentosa or Q. velutina? It is 
not that species and the leaves are good Red Oak leaves, and the fruit is 
good coccinea fruit. It is probably a form of the Red Oak with cups 
shaped like the northern form (Q. ambigua or borealis). I should think 

this was a tree worth further investigation. 


109 
January 13, a 
I enclose a leaf of an Oak specimen gathered by you in New Orleans 

October 1911. Was this tree planted? This is the same tree as the one 
which is growing at Natchez, Mississippi, and of which Harbison has 
found a single planted individual by an abandoned house near Selma. 
With the leaf is an acorn from one of the Natchez trees. At Natchez most 
of the leaves are still on the trees and perfectly green, so that if this tree 
has been planted in the streets of New Orleans you ought to be able to 
recognize it at this time. The same species grows on the Texas coast and 
it would be surprising, I think, if it does not turn up in West Feliciana. 


134 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


It is certainly an undescribed Oak and one of the largest Oaks of North 
America. It is well worth hunting for, therefore, in Louisiana. I have 
only just found out about the persistent leaves which add a good deal to 
the interest of the tree. 5 

I enclose also a copy of Buckley’s description of his Quercus Shumardu 
which has always been overlooked or disregarded. Judging from his de- 
scription, it is a tree with foliage a good deal like that of Q. texana but 
with cups as shallow as those of the Red Oak but covered with very thick 
scales. I enclose a couple of cups of what I suppose is this tree from 
Fulton on the Red River in Arkansas. Our Quercus texana collected last 
April at Lake Charles may be this tree, and Palmer appears to have found 
it at Natchitoches and Grand Ecore. Your Sardis 1906 and 1915 may be 
the same thing. ; 

I doubt if 1900 and 942 of Sardis are Quercus rubra, but your Sardis 
specimen of August 1913 is certainly this last. The trees which I think 
are Shumardii have more deeply lobed leaves than Q. rubra and large and 
very conspicuous axillary tufts of hairs on the lower surface. Typical 
texana has deep cups with thin scales. 

Unless some character besides the shape of the cup and the thickness of 
their scales can be found to separate Q. Shumardii from Q. texana I should 
think that the former was a variety of the latter, but this group needs a 
great deal more observation in the field. It is true that Q. rubra evidently 
grows in Feliciana, but I do not feel at all sure that it is in western 
Louisiana. It is important to collect more material of the Red Oak group 
about Sardis if you are there again, and particularly in Louisiana. 

I am writing to Palmer to pay especial attention to it in Arkansas, Okla- 
homa, western Louisiana and Texas this year. I should think that the 
Oaks of West Feliciana especially needed attention. I feel almost sure 
that you will find the new Natchez species there. If this tree from New 
Orleans, of which I now return a leaf, was planted where did the trees 
come from? Probably not very far from the city. This, however, is not 
a swamp tree so possibly it did not come from the immediate neighbor- 
hood of the city. 

Do you remember the peculiar Post Oak with white scaly bark growing 
in low wet ground west of Opelousas? The leaves are not pubescent on 
the lower surface like the peculiar Post Oak of the Natchitoches region, 
and apparently they lose the stellate pubescence from the upper surface 
very early in the season. We have never had the mature leaves of this 
Opelousas tree and fruit has never been collected; this is a Louisiana tree 
which certainly needs further investigation. Either it is a new species or 
a very distinct form of the Post Oak. 

I thought at one time the Hickories were bad but I must acknowledge 
the Oaks are more troublesome, and certainly they are now less well 
known than the Hickories. 

Quercus Shumardii.— {This name is followed by the direct quotation 
of Buckley’s original description, which ends the letter. |

January 15, 1916. 

Referring to the Opelousas Malus, No. 1 is from the clump which the 
negro carried you to see but which I did not see. This we call ioensis var. 
Palmeri. No. 2 is the solitary large tree with red-brown bark which we 
saw later but further east. This we first collected October 10, 1913. We 
have from you a specimen called No. 2 collected in April 1914, but there 
is not a trace of a flower on this specimen. 

On the label of your No. 1 collected April 1914 you say “large tree.” 
This I take for granted is the negro tree. On the label of No. 2 you say 
“large tree, not in clumps.” 

Don’t you think it would be a good plan for you to revisit Opelousas 
this spring and get good flowering material of this No. 2 which probably 
has very little to do with variety creniserrata? This will give you an op- 
portunity, too, to take a look at the peculiar Post Oak which does not 
grow very far from it and quite near the Quercus ludoviciana. 


111 
January 21, 1916. 

I have just finished looking through Palmer’s autumn collection of 
Oaks. His Natchitoches 8761 and 8762 represent my idea of Quercus 
Shumardii. The buds show that this tree is in no way connected with Q. 
rubra, but I expect it will be found to be a variety of Q. texana. This last 
is well represented by Palmer’s 8835 from Chopin. His Windsor 8935 has, 
as you see, shallower cups and appears to be approaching Shumardii. His 
Q. breviloba, Natchitoches 8718, is Q. Durandii and this is the first speci- 
men of this species which I have ever seen from Louisiana, although it 
used to be said to grow on the banks of the Red River at Shreveport. If it 
does grow there I have never seen specimens. This fine tree can now, I 
think, safely be added to the Louisiana flora. 

The next time you go to Covington would it be too much trouble to cut 
for me a piece of a stem of the //licium about six inches long and as large 
a piece as can be conveniently found? It is wanted here for one of my 
associates who is studying the anatomy of woods. 

Have you ever been to Port Hudson and do you know what grows in that 
region? I should like to go there again myself for it is fifty-three years 
since I saw it. Have you ever been up the railroad northward from Laurel 
Hill? This goes on to Woodville, Mississippi, which must be an entirely 
unknown Oak [region] botanically. 


112 
January 22, 1916. 
I have your two notes of January 18th and the two cups. The more 
shallow one with the much thickened scales is my idea of typical Q[wercus | 
Shumardii. The specimen with the thinner scales seems to me to be a 
shallow-cupped texana, that is it has the thin scales of that species. What 


136 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


I think is that these things run together and that Shumardii must be 
considered a variety of texana. It has been planted a good deal in the 
streets of New Orleans and I have collected there acorns with deep and 
with shallow cups. You say that your two trees can be distinguished in the 
field but how? It would be very useful if we could so distinguish 
Shumardii, otherwise than by the thickened scales of the cup and keep it 
as a distinct species. 

How large are the specimens of the Natchez Oak 1! in New Orleans? 
If these planted trees came from Covington it ought not be too very difficult 
to find these species growing wild there. Have you noticed whether the 
New Orleans trees are still retaining their leaves? 

I enclose an extract from Palmer’s last letter. Do you know these 
regions? 

“In Winn Parish, some distance n. e. of Natchitoches, there is a peculiar 
region with limestone bluffs and saline springs, so different from any of the 
surrounding country that it should produce something of botanical interest, 
also in going north from Natch. I passed through a region of nearly pure 
sand some miles south of Bienville where Quercus brevifolia seemed to be 
very common. I only saw it from the train but wished I could have gotten 
into it. If you are in that part during the summer and it is convenient I 
should very much like to spend a day or two with you about Natchitoches 
and Chopin, where there are a great many good things to be seen. The 
accommodations at Natchitoches are very good and I spent sufficient time 
about there to know something of the surrounding country.” Have you 
noticed whether the New Orleans trees are still retaining their leaves?

Many thanks for the package of specimens. The two Oaks are just my 
idea of Quercus texana. Malus +2 from Opelousas certainly should be 
followed up. It seems intermediate between angustifolia and ioensis and 
nearer the former. The bark as I remember it is different from that of any 
of our American species. This may be something new. 

We have a specimen of Magnolia collected by Mohr near Mobile with 
the cordate leaves of your specimen. The Mobile specimen has always been 
considered an acuminata, and I think it is probably a variety of that 
species. The leaves are not at all like what we call cordata. This of 
course is a tree to follow up. 


114 
February 8, 1916. 
I have been trying to group all the Tilia material in this herbarium with 
the following results as far as your specimens are concerned: 
Alabama. #1, bluffs of the Alabama River. A species with glabrous 
branchlets, thin cordate leaves stellate-pubescent below throughout the 
season. I collected specimens last April near Sardis and you collected it in 


™ Q. comptonae Sarg. 


eS

1914; no other date on the label and no number. This species has not been 
collected and these are urgently needed. 

#2, Tilia heterophylla Ventenat, not of Sargent’s Manual, = T. 
Michauxii of Nuttall but not of Sargent’s Manual. To this species I refer 
your numbers 780, 782, 790, 792, and many specimens collected by 
Harbison. 

#3, a glabrous species with very coarsely serrate leaves, your 6, 784, 
786, and 788, “near Selma, 1914,’’ and Selma, June 12, 1914. This might 
pass for a green-leaved form of 7. floridana if the leaves were not so 
coarsely serrate. If these specimens had been found in the north they 
would certainly be referred to T. americana. I feel very doubtful about 
this tree of which we have good material. Your specimen from West 
Feliciana, June 1907, called T. americana?, is evidently the same thing. 
This makes three species for Selma. 

Louisiana. +1, branchlets glabrous, leaves stellate-pubescent below 
through the season. Lake Charles, your 2530 from the Mills Place. I had 
supposed that the Avery Island plant with leaves pale pubescent below 
belonged here but I find on the upper surface of the leaves the remains of 
stellate-pubescent hairs. These are very unusual on the upper surface of 
Tilia leaves and the Avery Island plant may be something entirely distinct. 
I much want to see the very young leaves of your Lake Charles tree and 
fruiting specimens of the Avery Island tree. I have placed with the Lake 
Charles tree Palmer’s following numbers from Natchitoches Parish, — 

8747, 7946, 7397, 7474, 7554, 8013, 8021, 7420, and the specimen col- 
lected by you at Natchitoches April 15, 1911. Palmer’s 7675 from Welsh 
is probably the same as it has glabrous branchlets. All these specimens are 
very incomplete and we ought to have more and better Lake Charles 
material of this number. 

+2, a perfectly glabrous species with leaves green or more or less 
glaucous on the lower surface. This is our #2 of last spring from Lake 
Charles, and Palmer’s 7644, 7673, 8523, 7574, 7342, 7694, 8510, your 
2534, your Lake Charles specimen of March 26 and May 12, 1911, and 
your Shreveport specimen of June 1908. What I believe is the same species 
but with leaves more or less glaucous on the lower surface are Palmer’s 
7923, 8699 and 7569. These specimens with glaucous leaves I do not 
know how to distinguish from T[ilia] floridana of Small, and I do not see 
how to distinguish the glaucous and the green-leaved specimens specifically. 
We have only very incomplete material of this +2 from Lake Charles. 

#3, a species with glabrous branchlets, young leaves stellate-pubescent 
but soon becoming glabrous, and usually conspicuous tufts of axillary 
hairs. Your 2528 from West Feliciana seems to be this species which is 
our #3 of Lake Charles and Palmer’s 7523, 7956, 7554, 7479, 7474, 7952, 
7397, your Natchitoches specimen April 27, 1911, your Lake Charles 2530 
and 2536, Palmer’s 8511, 7695, your Lake Charles October 1914, your 
Winnfield April 6, 1913, our Opelousas April 3, 1913, your Laurel Hill 
March 1910. This seems a widely distributed species in Oklahoma, eastern 


138 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Texas and Arkansas, and gets into Mississippi. Our Louisiana material is 
still very incomplete, especially that from Lake Charles. 

+4, a tree with pubescent branchlets and leaves rusty tomentose below. 
Your 2532 (3 L. C.) from Lake Charles, and Palmer’s 7674, 8500, and 
perhaps 8494 but of this the branchlets are glabrous. I suppose that the 
“Tilia pubescens” of Avery Island belong to this species. There are no 
fruiting specimens of any of the above numbers and they are urgently 
needed. 


I should say then that there are certainly four species in Louisiana. If, 
as I suspect, the Avery Island specimen with young leaves stellate- 
pubescent above is a species, there would be five, and if the glabrous tree 
with very coarsely serrate leaves from West Feliciana can be separated 
from T. floridana, then there are six species. 

The important species to work up are the two species from Avery Island, 
the fruit of +4 from Lake Charles and the young leaves of your Lake 
Charles #3. It is important to compare young leaves of all the species 
because the conditions of their early pubescence may be very helpful in 
distinguishing the species. 

I had hoped that we had reached the end of the southern Tilias but 
evidently we are still very far from that I fear. It is astonishing how the 
peculiarities of the southern trees have been overlooked or neglected. 

There is confusion I am sure about that Mills Place Lake Charles 
number

February 10, 1916. 

I am sending you under another cover the cup of a very small Oak fruit 
and a cup and nut of a larger one. These seem to have been both gathered 
by me at Laurel Hill when we were there together. We have young leaves 
which belong to the small cup and these leaves seem to be Q. texana. The 
shape of the cup is all right for that species but of course is exceptionally 
small. The large acorn and cup would pass here at the north perfectly 
for a Red Oak. Unfortunately there are no leaf specimens which belong 
with this acorn. It appears to be in an exceptionally good condition if it 
was picked up from the ground in March, which was the time we were at 
Laurel Hill. 

If the Red Oak gets at all into Louisiana I suppose it would be in West 
Feliciana, and I am sending you this material in the hope that it may help 
you in studying this group. Of course it is desirable to determine, if we 
can do so, the true range of the Red Oak. Undoubtedly what has been 
called Red Oak in the south is often Shumardi. 

Ames and I are starting about the 10th of March for a short trip in 
Arizona, but my idea is to stop a day in New Orleans to talk matters over 
with you and then on the way back to stop again, if you think it desirable 
to do so, and return home by Natchez. All this, however, can be decided 
when I see you in New Orleans on the way west.

February 19, 1916. 

I have yours of February 15th. Please take another look at your Tilias 
784 and 788 from Selma. The flowering specimens look rather different 
but I cannot find much difference in the fruiting specimens. How do you 
distinguish these two trees? The truth is we have got to live with trees in 
order properly to understand them. Herbarium material is really of very 
little good except as a record. These two numbers look very much like the 
Tilia from west Louisiana. 

In order to meet engagements further west Ames and I would have to be 
in New Orleans on the morning of March 16th when I hope the crowd will 
have left. We had best write, I think, for our accommodations at the hotel. 
I should like to devote a part of the day to going over with you your 
specimens of Tilia and Quercus. Our plan now is to be back in Louisiana 
in April, but about this we can confer on March 16th. 


117 
February 23, 1916. 

I have just been through all the Hickory material of the 1915 collections. 
The most interesting thing for us now in Louisiana is your Natchitoches 
+6 of 1913 and 1914, for which I long ago wrote out a description, but I 
had so little material that I did not do anything more about it. I believe 
that Palmer’s Natchitoches 7258 (see this), which he called C[ arya] alba, 
may be this same tree, and I believe also that the two small trees which we 
found in dry woods just before we got to the quarry at Winnfield April 6, 
1915, may be the same. We thought at the time they were C. alba, 
but of course they have nothing to do with that species. These trees 
ought to be followed up, and if you cannot get there in the autumn perhaps 
Palmer can 

I suppose that those miserable Monroe Hickories which have bothered 
us so much, judging by the buds, all belong to C. arkansana, but they did 
not have good arkansana sn It would pay to get spring material which 
would show the young lea 

In spite of the very peauily shaped fruits which used to puzzle us so 
much I now believe that the following Natchitoches numbers must be 
referred to C. arkansana: Cocks 10, xi. 12, 16, 20, Palmer 1 and 3, also 
Chopin 1 of Palmer, Lake Charles 1 of Cocks, and Cocks and Sargent, Lake 
Charles (yard of J. Mills). 

Your Grand Ecore 3 of 1913 may also be C. arkansana with small 
globose nuts. It is important to see your leaves of this number. Can you 
find the tree or tell Palmer how to do it? Grand Ecore, Palmer 7524, 
Creston 7016 Palmer seem to be C. arkansana. 

1 and 18 of Natchitoches which I had placed with C. megocarpa |sic| 
are evidently C. arkansana. I feel very doubtful about 2 and 5 of Natchi- 
toches and I should like to see young leaves of these numbers. 5 may 
be C. arkansana but I am doubtful about 2. It is possible that the flower- 
ing and fruiting specimens are of different species. 


140 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


I hope you can get together all the specimens about which I have been 
writing you lately so that we can discuss them on the 16th of March when 
we shall not have any too much time I fear. 


118 
April 24, 1916 

I got home Saturday night after a successful two days in Natchez 
and one day in the neighborhood of Jackson where unfortunately Harbison 
did not turn up. ; 

Miss Compton has now located in Natchez twenty-nine or thirty indi- 
viduals of the new Oak. All the old trees are in the neighborhood of build- 
ings but some of these must be so old that I am inclined to believe that 
they must be original trees left standing when the forest was cleared. 
We saw, however, two wild trees, one growing in a field far from any 
houses and probably thirty or forty years old, and one much smaller in 
the woods. The relationship of the trees certainly would be Live Oak 
and I believe should be looked for on high ground and not in swamps. 
The largest specimen near Natchez is fully one hundred feet high and 
another tree has a trunk about five feet in diameter. Several of them 
are much larger than the tree we showed you on the Duncan place.” It 
is as evergreen as Quercus virginiana and is certainly one of the finest 
Oaks in the United States. I hope you will be able to locate the wild 
trees in Louisiana. 

The Maple tree from which we collected on our way to Natchez and 
which you thought was Acer leucoderme is evidently the same form 0 
Sugar Maple that grows in West Feliciana and is evidently a distinct 
form. 

I shall hope soon to hear about your visit to Sardis. I enjoyed our 
days together immensely and certainly West Feliciana can produce as 
fine trees as are to be seen in any part of the United States. 


119 

I think it would pay you when you are in West Feliciana Parish in the 
autumn to look into the Beech question a little and collect good fruiting 
specimens from a number of trees. I collected only two specimens this 
spring and these represent the northern species, F[agus| grandiflora, and 
the southern variety, var. caroliniana. The curious thing about it is that 
the under surface of the leaves is very pubescent. The pubescent 
grandiflora has been described as forma pubescens and apparently has 
only been collected before in New England. What is more interesting 
perhaps is that the leaves of the specimen of the variety caroliniana are 
also pubescent on the lower surface. This has been described as forma 
mollis. Apparently it has only been collected once before, at Tallahasseé 
by Nash in 1895, and in Louisiana (New Orleans) by Drummond 1m 
1832.

This collection seems to give you two new varieties for Louisiana. It 
would not be a bad idea to collect Fagus in any part of the state you 
may visit. 

I hope you are finding the new Oak. 

P.S. — The right name of the shrub we found so common and naturalized 
by the roadsides near Laurel Hill is Pyracantha crenulata Roemer. 


120 
May 10, 1916. 

Many thanks for the package of specimens which arrived yesterday. 

Tilias. 

820. This is the species with leaves stellate-pubescent on the lower 
surface while young, becoming glabrous, and small but conspicuous axillary 
tufts. This seems to be the commonest Linden of Louisiana and southern 
Arkansas. 

822. The glabrous, early-flowering species I suppose. There is a 
trace of axillary clusters on this particular specimen, the flower-buds 
appear although the leaves are not much grown. 

S54 = 822. 

836, T. heterophylla. 

832 = 822 and 834, I believe. 

4014 is what we have been calling T. floridana. 

4016, the species with pale pubescence on the lower surface of the 
leaves. This, according to the original description, should be T. leptophylla. 

4012 = 4016. 


4010 = 4014. 

2530 = 4016. 

Alabama 842 = Malus angustifolia. 

Alabama 844, Amelanchier. Mature leaves and fruit desired if not 
already sent. 

Quercus 838, Sardis. This certainly outdoes Shumardii as we have seen 
it in Louisiana. 

I notice that you are quite cautious about giving names to your Oaks 
and I do not know how to tell the young leaves of austrina from those of 
Durandii. 1 hope you can do so. 

Notice your 840 which has stellate pubescence on the upper side of 
the leaves. Is this a Post Oak? What is 830 from Pine Bank Creek 
with its long-stalked fruit? Can this be the Natchez tree or is it what 
you call Q. austrina? 

I hope to hear soon from you again. 


121 
May 23, 1916. 
Much obliged for your letter of March [sic] 18th. I am glad to hear 
that you found Carya pallida in Louisiana. I notice what you say about the 
lateness of C. alba. 


142 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


I have noticed in different places in the South individual trees of what 
I supposed was C. alba which were very much later in coming out than 
is usually the case with this tree. I have not been able, however, to 
follow up any of these trees to find out if they had other peculiarities. 
I suppose you can recognize in the autumn these late trees and it would 
be well, of course, to collect fruit and leaf specimens. These may show 
some characters which would make it possible to distinguish the late 
trees as a variety. 

I do not think I ever wrote you about Quercus velutina. My variety 
missouriensis was based principally on the stellate pubescence on the 
upper side of the leaves. I saw at Jackson this spring a small tree with 
these stellate leaves but the inner bark was not yellow like the inner 
bark of the common form of Quercus velutina. It is possible that this 
stellate pubescence and the gray inner bark may have some relationship 
and make it possible to distinguish another form of this tree. Harbison 
has noticed the same thing in Mississippi and western Florida, and I 
think it would be well for you to bear this in mind and keep a lookout 
for Black Oaks. 

There is certainly an undescribed species of Malus at Sardis, your 
numbers i., ii. and iii. The leaves on the flowering branches of this tree 
look exactly like those of M. angustifolia but the mature leaves, especially 
on the shoots, resemble those of some of the forms of M. ioensis. Possibly 
the angustifolia which you sent me the other day may belong to this tree. 
I have n’t got time to look at the specimens this morning however. I will 
write you later on this subject. Harbison says that the young leaves of 
Q. austrina are perfectly glabrous. 


122 

June 1, 1916. 
Have you ever collected Halesia carolina in Louisiana? If so, we have 
no specimen in our herbarium. My Manual speaks of it as growing 
through Louisiana to eastern Texas and Arkansas. West of the Mississipp! 
we have one specimen collected in northern Arkansas, nothing from 
Louisiana or Texas. It appears to be common at Selma. It is possible 

that the description of the range has got to be modified. 


123 
June 8, 1916. 

I am very glad indeed to get at last the Avery Island Tilias. They do 
not look at all as I thought they were going to and seem to be the same 
as three common species at Lake Charles. So much the better, for the 
fewer species we can get on with the better. 

What do you know about the distribution of Asimina triloba? We 
have Louisiana specimens only from Wakefield and Natchitoches. Does 
it grow in eastern Louisiana, and how does it happen that it does not 
grow at Sardis? We have no Alabama specimen whatever in the herbarium. 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 143 


124 
June 19, 1916. 

I have yours of the 14th from Sardis where I hope you are not suffering 
too much from the heat. I am just going to begin to arrange this spring’s 
collecting of Tilia and will write you again on that subject. 

I have given up trying to understand Q. Durandii and Q. austrina. 
Harbison, however, thinks he knows these trees as far off as he can see 
them and I am enclosing your note to him. The leaves of Q. Durandii 
vary more on the same tree than those of any other Oak I have seen. 
On the lower branches they are very often deeply lobed and higher on 
the tree entire, and sometimes green and glabrous below or pale and 
pubescent, although I believe the pubescent leaves are more common 
than the glabrous ones. 

I will ask Harbison to write you just where he found the Natchez Oak 
near Sardis and I hope you will be able to locate the tree and find others. 
Palmer has failed to find it where Mohr collected in Texas twenty-six 
years ago, so we know it only as a tree growing near human habitations. 


125 
June 30, 1916. 
Perhaps you will be interested in reading the enclosed from Harbison. 
Please let me have it back sometime. Notice what he says about the 
difference in Tilia at the top and bottom of the trees, and also about 
Quercus. You and he between you ought to be able to get to the bottom 
of this Quercus austrina business. 


126 
July 5, 1916. 
In spite of all our efforts the Louisiana Tilia material here is still very 
incomplete and unsatisfactory, as you will see by the following. My 
present idea is that Louisiana specimens can be grouped as follows: 
A. The perfectly glabrous species without axillary tufts of hairs. 
Lake Charles. 
Cocks, May 12, 1911, no number, good flowers. 
May 21, 1915, 2534, good flowers. 
Palmer, 7644 in bud, 8523 sterile. 
Sargent, river bank, April 12, 1915. #1 yard of C. J. Mills, sterile. 
River bank, April 13, 1915, #1, sterile. 
St. Francisville. 
Sargent, April 12, 1916. 
Laurel Hill. 
Cocks, March 1910, sterile. 
Natchitoches 
Palmer, 7569 in bud, 7523, good flowers. These Palmer specimens 
have leaves glaucous below but are probably a form of species represented 
by Group A. 


144 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Please notice that we have n’t a single Louisiana fruiting specimen 
of this group. The tree is common in Mississippi and reaches Texas and 
Alabama, and your Sardis 786, of which we have three fruits I think is 
the same. 

B. This is the species with large leaves very oblique at the base, 
early in the season very thin, bluish green, lustrous and slightly pubescent 
below, especially on the midribs and veins, usually soon becoming 
glabrous, axillary tufts small, often wanting. My +2 of Lake Charles, 
April 13, 1915, is my idea of this species. We also collected it March 26, 
1911. It is your 4014, Mills Place, April 3, 1916 

Lake Charles. 

Palmer, 7694 in bud, 8510, sterile (bracts but no fruit), 7695 in 
bud, 8511, sterile. 

Avery Island.

Cocks 401, sterile. 
Shreveport. 
Cocks, 10, June 1908. D. Coty, no date. 
West Feliciana. 

Cocks, 2540, flowers and fruit. 

I should have liked to have made my #2 of St. Charles the type of 
this species for the young leaves look so distinct, but if you can get fruit 
of Avery Island 4052 that might be taken as the type. This tree grows 
also in Texas and Arkansas but we have no very good material from 
those states. 


Sardis. 
Cocks 822 and 834, April 20 and 22, 1916, and 788, flowers and 
fruit complete 

I once Gok 788 belonged to Group C but the leaves are very 
oblique and bluish below. The tufts of hairs are prominent on this 
specimen, but I do not know how to distinguish these numbers from the 
Avery Island tree. Are 822 and 834 from the 788 trees? It would be 
well to get fruiting specimens of these numbers. Please write me, too, 
the sort of place in which this tree grows, the height of the tree approxi- 
mately, diameter of trunk, nature of bark, branching, and any other in- 
formation you can supply as we may have to take the Sardis plant as 
the type of the species in case we cannot get more Louisiana material.

surface, more pubescent than those in Group B, becoming glabrous, axil- 
lary tufts large and conspicuous.

during the season 
Lake Charles. 

Cocks 3, 2530, flowers, fruit and young leaves, and 2532. The branch- 
lets of 2532 are pubescent and those of 2530 are perfectly glabrous. How 
about getting fruit of 2532? 

Avery Island. 

Cocks 4054 in flower May 24, 1914, is evidently the same but the 
branches are more pubescent. 

October 18, 1900, a ree shoot. 

Welsh 


Palmer 7674, 8500, 8495, all sterile. 

E. Leaves smaller than those of the last group, mostly cordate, 
densely pale stellate-pubescent below during the season but the pubes- 
cence is not closely attached and can be easily rubbed off. 

Lake Charles. 

Sargent 3, April 13, 1915. Several sheets, all sterile. One specimen 
taken near the schoolhouse in West St. Charles [West Lake Charles in-

Palmer 7675, sterile. 

East Opelousas. 

Cocks, 4312 and 4016, sterile. 

Winnfield. 

Sargent, April 6, 1913, sterile. We have no fruit of this tree from 
Louisiana, and you do not appear to have collected any specimen in the 
state. 

The specimen of 2530 taken April 3, 1916, at the Mills Place seems 
to belong to E rather than to D. Are there not two species on that 
wretched Mills Place? 

This seems to make five species in the state, although it may be diffi- 
cult to separate B and C with the material we have 

At Sardis there is a Linden with oblong finely serrate thin leaves pale 
pubescent below during the season and obliquely cordate at the base. 
We have a sterile branch collected by you in 1914, no date and no 
number. I collected what I think is the same on the bluff near Sardis 
April 19, 1915, sterile shoots only. I don’t think this is your 788, and 
I don’t find that you have sent flowers or fruits. Possibly your Sardis 22 
and 23 belong here. These two sheets look abnormal. The leaves are 
very long-pointed, very coarsely serrate and oblique at the base. These 
trees should be followed up and more material obtained. 

Your Selma 784 and 6, and also several other unnumbered sheets col- 
lected in 1914, bother me a good deal for I cannot find any way to 
separate them from T [ilia| americana. T. americana, however, is a dis- 
tinctly northern tree as we now understand it and fees not appear to 
extend south of Pennsylvania and northern Missouri. Please look at these 
trees and see if the leaves are lustrous below and if there is any pubescence 
on them except the axillary tufts. I am afraid that your specimen from 
Wakefield, Louisiana, June 1907, is the same. 

Have you ever heard anything from our Laurel Hill friends and are 
they collecting any material for us? Don’t you think it would be a good 
plan to ask them to get fruiting specimens of all the different Lindens 
in that neighborhood?

Of the Quercus of your last sending two specimens (no numbers) called 
Durandii and austrina are both Durandii. 
958 is my idea of austrina. 960 I suppose is a good Durandii. These 
species are easily distinguished by the 
820 I should call Durandii. 824, probably apne 826, Durandii. 
840, Durandii. 830 I do not know but it may be aust 
958, 970, 956, 950 and 934 appear to be some iy : the Post Oak. 
The small tree by the stream at the foot of this hill where we were 
stuck, and called both austrina and Durandii, I now think is the Post 
Oak with scaly bark. 
4022, West Opelousas, is the Post Oak like that at Natchitoches. 
I enclose another communication from Harbison. Between you I think 
you ought to be able to clear up this Oak business this year. 
I take it that your Sardis Tilia 952 and 954 is the one I collected on 
the bluff near Sardis about which I wrote you the other day. This tree 
apparently grows at River Junction, Florida. We have no flowers or 


You called your Sardis 950 T. floridana. Have you ever seen this before? 

How does your Hickory which was so late in putting out its leaves look 
now? 

If you stay late enough in Alabama it would be a good idea to get 
some acorns of your peculiar hybrid Oak 938 to plant, as these hybrid 
Oaks are interesting and it is possible that it might be hardy here. 

Too bad that you and Harbison did not connect! 


128 
August 7, 1916. 

It is a long time since I have heard from you although Harbison wrote 
me the other day that he had a letter from you telling him of the floods 
in your region. I hope your crops are not ruined. Farming in the South 
seems to be a very precarious business. 

The young leaves of Quercus austrina as collected by Harbison are 
perfectly glabrous and I think all the specimens which you have sent 
under that name are either Durandii, which seems to be a common tree 
with you, or forms of the Post Oak. I trust you will be able to get a 
good supply of Quercus material so that we can settle this year some 
of these doubtful points 

I have pretty much come to a conclusion about Lindens, or most of 
them, and will write you on the subject in the course of a few days. I 
wish you would take a look at Magnolia glauca and perhaps make some 
specimens. Harbison has recently found a shrubby form with perfectly 
glabrous peduncles, while in the form which grows to a large tree the 
peduncles are densely covered with snow white silky hairs. At the north 
the plants are shrubby and the peduncles are glabrous. Most of our 


148 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


southern specimens have silky peduncles, especially those from Natchi- 
toches collected by Palmer. I do not think we have any specimens from 
Sardis and shall be glad to have them. 

If it is any hotter in Alabama than it is here today I am sorry for it. 


129 
August 9, 1916. 

I have this morning yours of en ae You must have had a horrible 
time and I fear that your crops are 

I think we are slowly getting a little light on the Tilia situation, but 
it is a tedious and difficult job because material is often so fragmentary. 
There are certainly a number of new species. I notice that your 2530 
from Lake Charles has perfectly glabrous branches and that 2532 has 
pubescent branches. We have flowers and fruit of 2530 but only flowers 
of 2532. I hope therefore that the new Louisiana collections may include 
fruit of this number. These numbers must represent the same species in 
spite of the branches. The lower surface of the leaves is covered with 
matted stellate pubescence which is easily rubbed off and not like the 
close persistent tomentum which you find on several of the Sardis species. 
This Lake Charles tree, which is also common in the coast region of Texas, 
does not seem to extend east of the Mississippi River. 

I hope soon to hear that things are in better shape in your part of the 
world. 


130 
August 26, 1916. 

Thanks = yours of the 21st which I find after a short visit in Illinois 
and St. Loui 

No, that eae won’t do for C. aprica. It is no doubt an undescribed 
species. 

I went to St. Louis to see Palmer who was arranging his spring collec- 
tion. He has a good deal in the autumn to do in Texas and I have told 
him that it was not absolutely necessary for him to get back into western 
Louisiana this autumn. He thought, however, he might do it. He reports 
very large trees of Quercus Durandii in Natchitoches, so that is another 
Louisiana tree. Apparently they are doing nothing in St. Louis in the 
way of distributing his plants and claim they are not going to distribute 
anything until they can make a critical study of them. I am sorry about 
this and if you can designate exactly what you need I will make another 
attempt to get them for you. 

If you get this note drop me a line as to where you are to be in 
Virginia as I am going there myself in September and it is possible 
we might meet. 


131 
September 28, 1916. 
I have yours of the 19th. I wrote you on August 9th & 26th & told you of 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 149 


the safe arrival of the specimens & suggested that we might meet in 

Virginia whence I have just come. Have you specimens of the late 

Carya alba about which you have written me or if not can you get them? 
I will write a real letter when my secretary gets home. 


132 
November 16, 1916. 

It is a long time since I have heard from you and I hope that silence 
does not mean that you are entirely swamped by those Alabama Oaks 
and Hickories. The Oak business seems to be endless, for now Harbison 
feels quite sure that he has found a new species near Vicksburg. I have n't, 
however, seen his material. 

I am writing especially today to tell you that we are sending you by 
mail two plants of a Chinese vine, Sargentodoxa cuneata. We think here 
it is going to be a good thing as in China, at least, it grows vigorously 
and has fragrant yellow flowers. Will you “place’’ these two plants where 
they will be likely to be taken care of? I am rather anxious about these 
because I am afraid this plant will not prove hardy in the north. 

Hoping to hear from you soon, I am, 


133 

November 18, 1916. 
According to Harper, “Mr. Mattoon of the U.S. Forest Service claims 
to have found Pinus caribaea in eastern Louisiana this year. Dr. Mohr 
did not seem to have any information about its occurring in Louisiana 
when he mapped its range, and I did not see any of it west of the Pearl 

River when I visited New Orleans in 1905.” 
Have you any views one way or another about this tree in Louisiana? 


134 
December 30, 1916. 
I very much fear there are three species of Tilia on Avery Island. 
First, Tilia floridana, Cocks 4052, May 29, 1916, and 4042, July 28, 
1916. 


Second, Tilia ambigua, n. sp., Cocks 4050, May 29, 1916; Miss 
Mcllhenny, June 8, 1915, ‘“‘the smooth barked Linden.” This is a common 
western Louisiana species and our No. 2 of Lake Charles. It is one of 
the trees which has been placed under lettophila [sic], gcease name I 
now want to abandon as the identification is not possi 

Third, Tilia Cocksii, Cocks (4054) May 29, 1916, (4040) July 28, 
1916. “The rough barked Linden,” Miss Mcllhenny, June 8, 1915. This 
looks superficially like some of the Lindens from the coast of South 
Carolina and Georgia which have been called Tilia pubescens but is distinct 
from them in its glabrous branches and buds. I have seen nothing like 
it except these Avery Island specimens and I wish we could find it in 
other localities. I hope, however, that we are going to Avery Island in 


150 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


the spring and then perhaps we shall be able to see more of these trees. 
This is only the first paragraph of the Linden dose I am going to 
send you very shortly. 
With best wishes for the New Year, I am, 


135 
January 2, 1917. 

I have determined some of your Alabama Tilias as follows: 

T. Harbisoni, n. sp., near Selma, 1914, Cock’s 780, 790 and 792. This 
is a common west Florida species and I think a good one. 

T. floridana var. oblongifolia, n. var. 788 type, 820, 832, 834, 952, 954, 
958, also near Selma 1914. This is a common Louisiana tree about which 
I shall write you later. 

T. nuda, n. sp. 95, June 6 and July 28, 1916; 954 (= 956 of 1915), 
June 28, 1916. Where is 956? I do not find it here. This is a perfectly 
glabrous species which is common in Mississippi, Louisiana, Arkansas 
and eastern Texas. Selma appears to be its most eastern station. The 
trees at Natchez, Mississippi, I have taken as the type. 

Hutchins’ Run, Cocks’s 970, July 26, 1916, with partly grown fruit. 
This differs from all other species of the United States’ Tilias which I 
have seen in the long hairs on the fruit, and if this is a constant character 
I suppose this is a distinct species. If you can locate the tree so that 
Harbison can find it in early spring; flowers and mature fruit will have 
to be collected either by him or by you. 

964, 966 and 968, Hutchins’ Creek, Cocks, June 27, 1916. This looks 
like what we have been calling T. heterophylla but flowers are needed. 
Can you locate these trees for Harbison? 962 Hutchins’ Creek may be 
the same but the branchlets are much more slender and the buds smaller. 

782, limestone cliffs of the Alabama River at Cocks’s place, June 15, 
1915, has slender light yellow branches and seems different from any 
of the others. 

836, young leaves, April 21, 1916. I do not connect this with any of 
your other specimens. What is it? 

Your Selma 1110, May 5, 1913, which seems the same as Selma June 
30, 1915, I cannot place. Complete material is needed. 

I am still in doubt about your Sardis species which we have thought 
might be T. americana, represented by your +6 of July 14 and #784 of 
June 2, 1915, by specimens collected in June 1914 and by #960, July 25, 
1916. Specimens from West Feliciana and from Alexandria seem to be the 
same. The axillary tufts of hairs which are so conspicuous in Tilia ameri- 
cana are smaller and often wanting from your specimens. Can you tell 
me if your #822, April 20, 1916, is from one of these trees? If not, 
Harbison ought to look them up and get young leaves. I suppose you 
can tell him where to find them. The fruit appears to be usually de- 
pressed-globose. I do not know, however, how to really distinguish these 
dried specimens from T. americana, but central Alabama is a long way 
from the home of T. americana. 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 151 


When we see how difficult it is to get complete material of these south- 
ern Lindens it is not at all surprising that they have been misunderstood 
and neglected for so many years. I am afraid there is still a good deal 
of field work to be done on them. If you can give Harbison the informa- 
tion how to find the doubtful numbers he can go there this spring and 
obtain the young leaves, always supposing that you were unable to do so. 
Of course you could probably find the trees much more easily than he 
could. In case you can not go will you get into communication with him? 


136 

January 4, 1917. 
Will you send me your full name so that it can appear with the 
description of Tilia Cocksii, also can you give me the Christian name or 
names of Miss MclIlhenny who sent me specimens from Avery Island? 
As you know, there are on the Louisiana coast region a number of 
islands similar to Avery Island. Have they ever been explored botanically, 
and don’t you think this ought to be done in connection with this Tilia 
business. It seems fair to presume that the vegetation on these islands 
would be very similar. We certainly ought to try to find Tilia Cocksii in 

more than one place. 


137 
January 6, 1917. 

I have referred the Louisiana species of Tilia as follows: 

Tilia ambigua, n. sp. Our Lake Charles #3, Avery Island, Cocks’ 
4050; Chopin, Palmer 7554; Creston, Palmer 7420; Welsh, Palmer 7675, 
8494: near Winnfield, Cocks and Sargent, April 6, 1913, East Opelousas, 
Cocks 4012 and 1016; on Little Bayou Teche, Cocks 4018. 

Please notice that we have neither flowers nor fruits of this species from 
Lake Charles. We have a very poor flowering specimen from Avery Island 
but no other flowers from the state, and fruit only from Little Bayou 
Teche. 


T. floridana, Small, West Lake Charles, Cocks, October 1914 (no 
number) ; Lake Charles, Cocks 2536, 2530, 4014; our #2 of Lake Charles; 
Palmer, Lake Charles, 7695, 8511. 

Notice that from Lake Charles we have partly expanded flowers on 
your +2536 but no other flowers and no fruit at all. 

Avery Island, Cocks, 4052 and 4042. Grand Ecore, Palmer, 9449; 
Chopin, Palmer 7970, 7342; Natchitoches, Palmer, 7574; Shreveport, 
Palmer, 9479, 10608; Welsh, Palmer, 7673; East Opelousas, Cocks, 4010, 
4020; West Feliciana, Cocks, 2540; St. Francisville, Cocks, 2528; near 
Laurel Hill, Cocks and Sargent, April 12, 1916; West Plantation, Bayou 
Sara, Cocks and Sargent, April 14, 1916. 

There is good material from Avery Island. 4020, East Opelousas, has 
good fruit. 2540, West Feliciana, has a few open flowers. All the other 
specimens are very incomplete. 


152 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Tilia floridana, var. oblongifolia, n. var. Laurel Hill, Cocks, March 
1910; Natchitoches, Palmer, 9437, 8699, 9416, 7956; Grand Ecore, 
Palmer, 7523; Chestnut, Palmer, 9462. 

Natchitoches 7956 has good ae si there are no other flowers and 
no fruit of any of the Louisiana speci 

Tilia rhoophila, n. sp. Lake Chars, Cocks 2530 (I am doubtful about 
this), 2532; Welsh, Palmer, 8500, 

There are good flowers of 2532 aed no ies and all the Welsh material 
consists of young shoots. 2530, Lake Charles, has glabrous branches and 
buds and may be 7. Cocksii. This species, if it is one, needs investigation 
in Louisiana. 

Tilia nuda, West Feliciana, Cocks, 4024; Lake Charles, Cocks, May 12, 
1911, 2530, 2534, Palmer 7644, 8523, our #1 of Lake Charles. 

T. nuda, var. glaucescens, n. var. Natchitoches, Palmer, 7569, 7923. 

The type of this new variety is Cocks Sardis 786. We have no flowers 
or fruit of the variety from Louisiana, and only two fruits from Sardis 
and none from Texas 

With T. Cocksii this makes five Louisiana species without the Sardis 
species with coarsely serrate leaves like those of T. americana which, 
judging by the two fragmentary specimens, also grows in Louisiana. On 
the whole our Louisiana material is not at all satisfactory. When we 
remember how much time and trouble we have taken to get together the 
small amount we have it will perhaps be understood why these southern 
species have been so much neglected and overlooked. Certainly there is 
no other genus which is more difficult to collect material in a saitsfactory 
condition. 

A common Lake Charles tree our #2 with leaves at the end of May 
very thin, blue-green and nearly glabrous below is interesting. It belongs 
with the floridana set but perhaps should be distinguished as a variety. 
Palmer 7694 and 8510 from Lake Charles may be the same but I am 
not sure, and probably Natchitoches 8697 may be the same form. We 
have no flowers and no fruit of this tree from Lake Charles and we 
ought to try and get them. I take it for granted that you know the form 
I am talking about as you collected it at Lake Charles March 26, 1911 
(no number). 

I wish you would think over the situation and decide if possible if you 
will be able to obtain some of the material we need this year. The im- 
portant things to get are flowers and fruits of this Lake Charles Tilia 
floridana, and material and information of T. rhoophila from Walsh. 
Palmer has a good deal of Tilia work to do in western Texas this year 
and it is desirable that it be arranged so that we will not be obliged to 
go into Louisiana at all this season. I take it for granted that you will 
be able to get off for a week or ten days about April Ist for a trip into 
western Louisiana, and also for your proposed expedition with me into 
the country adjacent to the Illinois Central Railroad. Apparently there 
are no Lindens in East Louisiana except in West Feliciana; we at least 


—— ER ate ss tea 


a 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 153 


do not seem to have any specimens from that part of the state. How 
about this? 

As the nature of the pubescence is the best character by which to 
distinguish the various species it is essential to collect in the spring the 
half-grown leaves. It is necessary therefore to visit trees three times, in 
the spring for young leaves and in the summer and early autumn for 
flowers and fruit. The color of the branchlets and the character of the 
winter-buds have been almost entirely overlooked, and it will be laborious 
and expensive to get these in addition to the spring and summer material. 
All these southern trees ought to be grown in New Orleans where they 
could be easily seen and ih ee studied. You need an arboretum 
there very badly. 


138 
January 12, 1917. 
I enclose a provisional conspectus of the United States species of Tilia 
based on the material already in hand. It will require considerable chang- 
ing probably when we are successful in getting all the material we need 
this year. I am sure we have n’t got to the bottom yet of the distribution 
of these trees. For example, we know nothing of Lindens in Louisiana 
east of the Mississippi River with the exception of those in West Feliciana; 
certainly there must be others. And we know nothing of Lindens in any 
of the coast region of Mississippi or Alabama, Selma and Sardis being 
the most southern station in Alabama from which I have seen specimens. 
There must be Lindens on or near the gulf coast of Mississippi. If you 
do not mind doing so I wish you would ask Tracey [sic] if he has not 
collected Lindens along the southern coast. Lindens are so common on 
the Carolina and Georgia coast, and so common in places like Lake 
Charles, that it would be surprising if they did not occur in the coast 
region east of the Mississippi River. 
Many thanks for your letter just received this morning. I will make 
the corrections you suggest and write you again in a few days.

February 9, 1917. 

Hickories. 6 of Natchitoches, We used to think this was a new species 
but I am convinced that the flowering specimen collected in April 1914 
is C[arya| alba, and that the fruiting specimen collected in October 1913 
and the fruit is C. arkansana. 

#1 of Natchitoches, October 1913, seems to be C. ovata. 

The Carya in dry woods before reaching the quarry at Winnfield, a 
tree with slender glabrous branches, young leaves nearly glabrous above 
and hoary-tomentose below. This is not arkansana, alba, ovata, ovalis, 
megacarpa, callicoma or luchieieilc What is it? It has always bothered 

P me. Can’t you settle this problem this year? 

Carya #5, Natchitoches, Cocks, October 1913. This has stout glabrous 
branches, buds the size of those of C. ovata, and stellate pubescent rachis 
and midribs of the leaves. The fruit is pear-shaped with a thick husk 
splitting tardily and looking like some of the forms of C. arkansana. 
Unless there is some mixup here I do not know it, but if the fruit and 
leaves do not go together I do not know the leaves unless they may be 
some extreme form of ovata. 2 and 17 of Natchitoches seem the same. 
I once thought that 17 was a callicoma but these Natchitoches numbers 
have small obtuse buds covered with yellow scales and are entirely different 
from the buds of callicoma. The young leaves of 2, however, show no 
trace of the yellow scales, so that it cannot be an arkansana. Another 
species? I hate to think so. Some of the other Natchitoches and Grand 
Ecore numbers which I have placed with arkansana may be the same 
thing and it is possible, of course, that this may represent another species 
for western Louisiana seems capable of anything in the tree line. 

n Have you found out anything more about that Alabama alba which 
i leaves out so late? I think I saw the same thing once near Natchez. It 
may be some variety which we have not got hold of yet. I wish you 
would go over your Hickory material and see if you can throw any 
light on any of the numbers I have written to you about today. I had 
hoped that we had finished the Louisiana Hickories but there seems to 
be still a little to do at Natchitoches and especially at Winnfield.

Here are some of the results of Rehder’s visit to New York: 

Vitis rufotomentosa. The Louisiana specimen referred by Small to this 
species of his was collected by Hale near Alexandria and was called by 
him V. aestivalis. The best character by which V. rufotomentosa can be 
distinguished from V. aestivalis is in the pubescent branchlets and pedicels. 
According to this Palmer’s 7974 from Chopin, Louisiana, would be V. 
rufotomentosa. Harbison has found it at River Junction, Florida, so 
there is no reason why it might not grow in Louisiana. I shall ask Harbi- 
son to look for it in Alabama and Mississippi. If you want therefore to 
keep V. rufotomentosa distinct from V. aestivalis you can include it in 
your Flora on the strength of Palmer’s specimen. I do not believe myself 
that it is very much of a species. The Vitis ni pubescent stems, how- 
ever, ought to be looked for in eastern Louisian 

Of Vitis caribaea, which Small also credits nm Louisiana, there is no 
specimen in the New York herbarium, and only four from Florida. On 
one of these some one has written ‘Florida to Louisiana.” I think you 
can safely drop this species as a Louisiana plant for there is nothing to 
show that it grows there 

Bumelia lucida Small. This is based on a specimen collected by Car- 
penter in 1838. His label reads, “No. 19, Prinos new? Small tree 10-20 
feet high; limbs rigid, some short ones resembling thorns. Grows in thick 
woods, Feliciana, Louisiana. Flowers in June and Ist of July; berries 
purplish black. Dr. Carpenter, 1838.” Before Small got hold of it some 
one labeled it “B. lycioides Pursh.”” I should think it probably a form of 
B. lycioides. It certainly does not look, however, like your specimen of 
that species collected at Wakefield in 1907. You may be able to find 
Carpenter’s plant yet. In the shape of the leaves it looks like a sterile 
specimen collected by Letterman near Opelousas in August 1882 and 
preserved in the St. Louis herbarium. 

Bumelia cassinifolia Small is based on a specimen collected by Letterman 
in August 1883 near Opelousas. We have a photograph of the type speci- 
men and a single leaf. The leaves are obovate, rounded at the apex, thin, 
glabrous and not conspicuously reticulate. This specimen is certainly 
different from that collected by Letterman referred to above and preserved 
at St. Louis. We have what seems to be the same as Small’s B. cassini- 
folia from Paradise Key in the Everglades of Florida, from Mosquito Inlet 
and St. Marks, Florida, and from near Bainbridge, Georgia. This last is 
a shrub growing in moist soil. These Florida specimens have slender 
glabrous pedicels and rounded calyx-lobes. 

I think you ought to be able to find this plant near Opelousas. If not, 
I should think you could include it in your Flora on the strength of 
Letterman’s specimen in New 

Of B. lycioides we have from Louisiana only your Wakefield specimen 
and we should have more of it and know more about the distribution of 
this tree in the state. I think it must be common in western Louisiana.

Your unnamed Vitis No. 9, Richmond Parish, June 1909, is V. palmata. 
This seems common in western Louisiana as Palmer got it at Monroe and 
Natchitoches. I suppose you have Palmer’s specimen No. 8006, V. rupes- 
tris from Natchitoches, June 1915. 
I am sorry to hear that there is another den of Tilias in western Louisi- 
ana for I fear it is filled with trouble. I suppose you will pay a visit there 
and I shall be glad to hear of the results.

Do we know enough about C[arya| leiodermis and have we ever had 
fruit from more than one tree? Except by the color of the young leaves 
and by the much thicker husk of the fruit can /eiodermis be distinguished 
from callicoma? Are you sure that the young leaves of leiodermis are not 
red or sometimes red? We ought to have a great deal more fruit of these 
two Hickories. Even if the distinctive characters hold good might they 
not better be considered varieties of one species? Why cannot our un- 
known Winnfield Hickory be leiodermis, of which we have no very young 

leaves?

Biloxi is a wonderful place for Live Oaks and I wish you had been 
there with us. There are two very distinct forms, one with young leaves 
nearly grown and pale and slightly pubescent on the lower surface. These 
trees are like the one which we collected at Springfield. The second form 
is a tree still covered with last year’s leaves which are dark green and 
very lustrous on the upper surface, coated below with thick white tomen- 
tum, strongly revolute and very conspicuously reticulate-venulose. These 
trees were not in bloom and have lost none of their old leaves. T his 
second form was what I supposed was the typical Quercus virginiana. 
We saw nothing like it in Louisiana. It would be strange, however, if it 
did not extend into the southeastern part of the state and I should expect 
it at Slidell. Have you ever been there? 

I understand that your Live Oaks at New Orleans are green and glabrous 
on the lower surface and I wish you would dry me some specimens show- 
ing their present condition. I very foolishly omitted to do this and in this 
herbarium there is only one specimen of Q. virginiana collected by me in 
western Louisiana many years ago. I do not find in our Texas material 
specimens with leaves as thick and tomentose as those on the trees of 
Biloxi but what appear to be a good many intermediate forms. It is 
evident that Q. virginiana has been shamefully neglected. 

That curious White Oak which we found in the road from Springfield 


158 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


seems to agree with Michaux’s Q.[uercus| alba repanda which is a 
name for it. It would be interesting to get good leaves and fruit from this 
tree which seems to be exceedingly rare. 

We are having today what appears to be the severest snow storm of the 
winter and I wish I was back in some comfortable place like Opelousas, 
although I daresay Ames does not share this opinion. I will write again in 
a few days as soon as I get things a little in order. I think we had a 
wonderfully good trip this year. I can’t have too many Live Oak specimens 
from different trees.

April 11, 1917. 

T. W. Adams, Greendate, Canterbury, is the name and address of the 
New Zealand man who cultivates Conifers and Oaks so successfully and 
apparently has a wonderful collection of trees. I wonder if your people 
know him. 

I have a note that Pinus glabra grows on the Amite River. Did you 
supply this information and, if so, can you give me the exact locality 
where you found the tree? This must be the extreme western limit of its 
distribution. 

I understand that the only place where you have found Kalmia latifolia 
in Louisiana is in Washington Parish. If so, this is probably its western 
limit and the talk in my Manual of its occurring in western Louisiana and 
southern Arkansas must be incorrect; at any rate we have no specimens 
here from that region. 

In the March issue of Torreya which arrived this morning there is an 
article by Wilbur R. Mattoon of the Forest Service on the extension of the 
range in Louisiana of Pinus caribaea. According to him there are pure 
stands of this tree covering mile after mile along the New Orleans Great 
Northern Railroad, and that logging and turpentine operations are carried 
on there by several large companies. He observed it between Slidell and 
Covington. From Covington to Hammond he found it confined to ponds 
and along streams, and spread over large areas of flat lands further east. 
About Hammond he noticed it quite common in young stands and scattered 
groups. This was the most western point this man visited. He says that 
“its occurrence south of Hammond along the Illinois Central right-of-way 
suggests the high probability that it occurs to the north and to the west 
doubtless as far as the natural barriers formed by the extensive outlying 
swamp and overflow lands of the Mississippi River.” He says, — “The 
region, it would seem, affords an excellent opportunity for some one to look 
for a further extension of the western limit of this interesting and very 
valuable commercial Yellow Pine.” How about this, and if it does grow at 
Hammond how did we happen to miss it? This seems to be a thing to look 
into. I will try and get some of Mattoon’s specimens, but as Hammond is 
of easy access from Louisiana you will no doubt have an opportunity to 
verify his observations.

Was it Jlex cassine myrtifolia or Ilex lucida which you said you had not 
been able to find in Louisiana? We have a specimen of /lex lucida from 
you, your Pearl River No. 81, no date, with //ex Dahoon on the label. In 
our herbarium I do not find any /lex cassine myrtifolia west of Alabama. I 
saw a plant of //ex cassine (Dahoon) growing in the lake at Avery Island 
but failed to take a specimen. We have no Louisiana specimen of this tree. 
It does not seem to be anywhere very common, and I should like to know 
about its distribution in Louisiana and to get Louisiana specimens if 
possible. 
Ilex lucida is common at Biloxi.

April 16, 1917. 

Is the Tilia by the river (the tree I did not see) from which you collected 
this sprig the same as your 2532 (3 Lake Charles) of May 21, 1916? 
Your 2530, June 1, 1915, from the Mills Place seems the same. If these 
are all one species T. rhoophila as a Louisiana tree will have to disappear, 
and we should have to consider that the young branchlets of 7. ambigua 
are sometimes pubescent and that the pubescence of the leaves of this tree 
sometimes becomes brown before the end of the summer. 

Tilia Cocksii. I understand that your 4040 and 4054 are from the tree 
at Avery Island which you showed me. If this is true it would seem that 
there is no way of really learning anything about these southern Linden 
trees except by visiting them every day from March 15th to September Ist. 
My last visit shows that there is no use trying to do anything with them 
worth while with only herbarium specimens gathered twice a year to depend 


on. 

The Carya by the roadside near Loranger with slender branchlets and 
stellate pubescent young leaves and evidently small buds may be some 
form of C. alba but I think you should try and get the fruit. These trees 
seem to be the only strange-looking Hickories we saw this year. 

As I understand it C. callicarpa becomes C. leiodermis, C. letodermis 
becomes a variety, and C. ovalis subglobosa becomes C. leiodermis, which 
is something gained. 

I enclose a bit of my specimen of the Winnfield Hickory which does 
not look like what you showed me. Is it possible that my specimen is 
C. leiodermis. What seems to be the same tree grows at Natchez. I think 
it desirable to investigate Winnfield in the autumn. There is that com- 
paratively smooth Bumelia from Avery Island which needs further inves- 
tigation. Can you manage that? 

Don’t you want to lend me the fruiting specimens of the new Oak with 
rhombic leaves which you showed me the other day? I am afraid that we 
shan’t be able to get fruit of this tree this autumn owing to spring frosts.

ANATOMY OF THE PALM RHAPIS EXCELSA 
I. MATURE VEGETATIVE AXIS? 


Martin H. ZIMMERMANN AND P. B. TOMLINSON 


DIAGRAMS PURPORTING TO REPRESENT the course of vascular bundles 
in palm stems are reproduced frequently in textbooks. These seem to 
be based less on direct observation than on figures copied from earlier 
publications. Reasons for this are obvious. Palms are essentially tropical 
organisms and are not commonly available to research workers. More- 
over, palm stems are too large and too complicated to lend themselves 
easily to standard botanical microtechniques. Workers of the nineteenth 
century, despite their limited technical facilities, made much more prog- 
ress than their modern counterparts. 

Von Mohl’s classic and unexcelled work (1824-1849) is the prime 
source of our present understanding of the anatomy of the palm stem, as 
has been shown in surveys of the history of the subject (Branner, 1884; 
Monoyer, 1925; Tomlinson, 1961, 1964). The development of this under- 
apr up to the time of Von Mohl and subsequently has been traced 

noyer and is best illustrated by the series of diagrams in Fic. 1, 
cia et largely from his paper, together with Monoyer’s diagrams of 
the stem of “Cocos botryophora” (Arecastrum romanzofianum (Cham.) 
Becc., see Moore, 1963), based on his own observations and reproduced 
here as Fic. 2. In addition to surveying the literature both Branner and 
Monoyer made significant contributions to the subject. Branner attempted 
to explain the distinctive curvature of individual leaf traces in palm 
stems as a mechanical consequence of their appearance in the meristema- 
tic region of the palm stem (cf. also Schoute, 1903; Arber, 1925, p. 35 a) 
According to Arber, Von Mohl appreciated the mechanics of the curvature 
in 1858. 

Monoyer was concerned much more than previous workers with anas- 
tomoses between individual bundles and the way in which the vascular 
network constitutes a pathway for long-distance transport. His own 
diagrams (Fic. 2) illustrate a regular system of bundle fusions. He 

*This is a contribution to a major research program in which the as of 
arborescent monocotyledons is being studied by one of us (P.B.T.). The gram is 
supported by grants from the National Science Foundation (G.B. 506) aoe the 
American Philosophical Society (Penrose Fund 2959, Johnson Fund 488). 

Subsequent articles will deal with leaf, root, and inflorescence insertion, seedling 
and cae anatomy, and general development.

shows a presumed bundle fusion (his P/. V/IJ, Fig. 4) without com- 
menting on anatomical details. Previously Lestiboudois (1840) and 
Karsten (1847) had recorded presumed fusions, but they were based 
on macroscopic dissection only. All other illustrations of fusions appear 
to have been inferred rather than observed (e.g., Fic. 1 E). Our own dye 
injection experiments suggest that interconnections between different 
vascular strands are numerous and physiologically very significant. 

Monoyer’s work was also important in suggesting differences between 
proximal and distal parts of a single palm stem (Fic. 2). This is a point 
overlooked by theorists who ascribe a simple “type” of construction to 
all palm stems. 

We suspect that the essential features of the distribution of vascular 
bundles in palm stems has hitherto not been grasped except by Branner 
(1884). Early concepts of the growth of palm stems, now known to 
be false, were used by De Candolle (1813) in separating monocotyledons 
from dicotyledons as a major group. Monocotyledons do indeed differ 
in their basic construction from dicotyledons, but not in the way envisaged 
by De Candolle. The so-called “palm-type” of bundle distribution has 
long been regarded as one of the basic patterns in monocotyledonous 
construction (e.g., Falkenberg, 1876). It would evidently be useful to 
establish these concepts more factually. 

The present article is the result of the reappraisal of the problem at 
first hand. Von Mohl’s general principles have been established on a 
quantitative basis for the first time and many new observations made. 
A much more accurate understanding of the structure of the palm stem 
and of the pathway for long-distance transport has now been reached. 

Earlier observers give little indication of methods used in analyzing 
palm stems. Large scale dissection, particularly of partly decomposed 
trunks, has evidently been most used. This gives general information 
about the behavior of individual bundles, but the intimate relation be- 
tween different bundles is lost, and anatomical details are overlooked. 
Macroscopic dissection cannot distinguish easily between temporary juxta- 
position of two bundles, which is frequent where they are congested, and 
true vascular anastomoses which are physiologically and developmentally 
important. Serial sections, less used by previous workers, have been 
mostly of small palms (e.g., Nageli, 1858). 

Our own study is largely based on serial sections, which means that 
the relative position and detailed anatomy of vascular bundles is preserved. 
Anatomical information is stored on ciné film so that large scale analyses 
which are needed become a relatively simple matter. In addition, this 
dynamic approach makes it easy to distinguish between important and 
unimportant vascular contacts. 


GENERAL MORPHOLOGY OF RHAPIS 


The problem was simplified by using the small palm Rhapis excelsa

south Florida, Aérial stems 2-3 cm. in diameter and up to 5 m. high 
arise from horizontal rhizome segments up to 1 m. long. Younger, de- 
veloping parts of each rhizome segment are protected by short, rigid scale 
leaves which are morphologically equivalent to the sheathing base of 
the foliage leaves of aérial stems. In older parts of rhizomes the scales 
decay, leaving annular scars at intervals of 1-3 cm. marking the nodes. 
Adventitious roots arise at wide but fairly regular intervals along the 
rhizome, commonly, but not exclusively at the nodes. After a period of 
hortsontal growth the apical part of the rhizome enlarges appreciably and 
turns erect. There is a rapid change from rhizome scales to normal foliage 
leaves, the transitional leaves with increasingly developed blades illus- 
trating that the scales are essentially foliage leaf sheaths without a blade. 
In the axils of several of the most distal rhizome scales new vegetative 
buds grow out as the rhizome apex turns upwards. Most of these lateral 
branches grow out horizontally as new rhizome segments; occasionally 


In the distal parts, axillary inflorescences appear, internodes are shortened

and the outline of the stem becomes more angular owing to the pressure 
of developing inflorescences. The anatomy of this part of the stem will 
be described in a subsequent article. 

By choosing a palm of this stature the problem was reduced from the 
analysis of a stem like that of Cocos, which may be up to 0.5 m. in 
diameter with over 20,000 vascular bundles at any level, to one in 
which there were about 1,000. The relative ease with which the Rhapis 
stem could be sectioned freehand was a second reason for its selection. 
Clearly, principles based on the study of a diminutive palm must be 
verified by analysis of a much larger and more typical stem. The basic 
approach used in this work suggests that ultimately this will be possible. 
However, we already have much evidence from larger palms like Chrysali- 
docarpus, Sabal, Washingtonia, etc. which suggests that Rhapis is indeed 
a small-scale model for palm stems generally. 


CINEMATOGRAPHIC ANALYSIS 


Cinematographic analysis was accomplished by two different methods, 
namely, by photographing, frame by frame, (1) sequentially cut surfaces 
and (2) serial sections through the microscope. Kodachrome II, Type A 
film has been used throughout. 

Surface photography. Photography of cut surfaces has been used 
only to a very limited extent with Rhapis. Pieces of stem were clamped 
in the specimen holder of a Reichert type OME sliding microtome, and 
thin shavings were taken with a frequently sharpened knife. The speci- 
men holder was advanced for each cut along the optical axis of the 
camera, i.e., manually with the screw which raises the specimen holder. 
The specimen holder was modified in order to accept long pieces of stem. 
A scale marked in ink on the stem provided a means of measuring the 
rate of advance. The camera, a Bolex H 16 REX, was mounted on a 
sturdy stand above the specimen with the optical axis coinciding with 
that of the stem. A long focal-length lens (105 mm.) allowed the operator 
of the microtome ample working space. We developed this method our- 
selves but learned during the preparation of this manuscript that a 
similar, but automatic method for the analysis of short tissue pieces had 
been developed earlier by Postlethwait. In fact, the method seems to 
have been proposed as long ago as 1907 (Postlethwait, 1962). 

Photography of serial sections. For the analysis of the course of

vascular bundles over long distances, sections 25—50u thick were cut 
freehand on the same microtome at intervals of 0.5 mm. The automatic 
feed was set at 50u and every 10th section kept. For easy processing 
each of the sections retained was tied with a constant orientation to a 
sequentially numbered slide by cotton thread. Orientation was facilitated 
by a shallow longitudinal groove scored along the stem and visible as 
a slight notch in each section. A small wad of glass wool between cotton 
thread and section prevented unstained thread marks across the section. 
Sections were bleached briefly in “Clorox,” washed in water and 70% 
ethanol, stained overnight in a mixture of safranin (95 parts of a 1% 
solution in 70% ethanol) and Delafield’s haematoxylin (5 parts), dif- 
ferentiated briefly in acidulated 50% ethanol, dehydrated, and mounted 
in neutral ‘“Piccolyte.” Sections at 0.5 mm. intervals proved adequate 
for general analyses as it was easy to trace a single bundle from section 
to section. For details of “rapid” changes which occurred at a node a 
complete series of sections approximately 30, thick were prepared, pass- 
ing through an entire internode about 2 cm. long which had been embedded 
in celloidin. 

A piece of stem much longer than could be held complete in the micro- 
tome clamp was analyzed in shorter lengths. The upper part of each 
of these shorter segments was clamped in the normal way and as many 
sections as possible removed, then the lower part was held firm by 
freezing, in a 5% gum arabic solution, to the flat stage of a freezing 
attachment and the sectioning of the segment completed. We have now 
greatly simplified the procedure by the development of a modified clamp 
with which very long pieces of stem can be held. 

The key problem is to match successive sections under the microscope 
so that a fixed point in the section successively occupies the same position 
on each frame of the film. So far this has been done by incorporating 
a camera lucida into the microscope-camera system in such a way that 
an outline drawing of every 2nd to 6th section is made and used to orient 
its successors precisely. The drawings are used as an additional per- 
manent record, with the microscope-stage coordinates marked for about 
every 10th slide, so that, if necessary, it is possible to return to the slides 
at any later time and locate the photographed position. A Wild M20 
microscope was used, with the parts assembled from below upwards as 
follows: microscope base with centerable rotating mechanical stage, ob- 
jective turret, drawing tube, camera tube H, binocular. Viewing and 
focusing are done in the binocular; photographs are taken with a Bolex 
H 16 REX, which is mounted on a Wild camera stand. 

It is often not necessary to have a permanent record of drawings and 
photographed slide positions. The extra labor of drawing can be eliminated 
with an optical “shuttle” system. A Wild discussion tube is mounte 


graphs are taken alternately through each microscope, the double image 
being used merely to superimpose successive sections precisely. 


1965] ZIMMERMANN & TOMLINSON, RHAPIS EXCELSA 167 


Analysis of films. For the analysis of films an L-W 224 A Photo- 
Optical Data Analyzer was used. This is essentially a 16 mm. movie pro- 
jector modified by L-W Photo, Inc. (15451 Cabrito Road, Van Nuys, 
Calif.), so that a film can be projected without flicker at any speed from 
1 to 24 frames per second, forward or backward. The film can be 
stopped instantly, and moved frame by frame. Less expensive projectors 
are available, and action editors are also usable for the purpose. How- 
ever, the instrument we have used has proved ideal in every respect. 

The vascular system of Rhapis described below has been resolved by 
an essentially dynamic process. This is reflected in the subsequent 
description which refers to the distribution of vascular bundles by a 
dynamic terminology. This is merely a convention. Changes in direction 
of mature bundles reflect changes in the angle of differentiation of bundles 
in meristematic regions. “The “movement” suggested by ciné analysis, 
particularly of one bundle in relation to another, is quite apparent and 
implies neither actual movement of bundles nor their growth. 


GENERAL STEM ANATOMY OF RHAPIS

pheral part of the sclerotic isthmus. Xylem enclosed by thin-walled, slightly 
lignified parenchyma less abruptly delimited from ground tissue than phloem 
sheath; rarely including a few fibers. Cells immediately surrounding vessels 
with wide pits and distinctly differentiated from remaining xylem parenchyma. 
Tracheal elements? including one or two metaxylem vessels 40-604 wide, 
circular in transverse outline, and usually some narrow protoxylem elements. 


perforation plates with few (4-10) thickening bars on oblique end walls; 
protoxylem either long imperforate tracheids with annular or helical wall 
thickenings or somewhat shorter vessels with unspecialized perforation plates 
transitional to metaxylem elements. 


Variation throughout a single stem largely involves an increase in lig- 
nification with age. Stems vary much in vigor of growth and this is re- 
flected in differences in diameter and length of internodes and total 
number of vascular bundles. Absolute measurements may be misleading, 
the best comparative unit is the internode. Differences between axes in 
juvenile and adult stages of growth have not yet been examined. The 
following paragraphs deal with overall distribution and types of vascular 
bundles in the adult mature stem; subsequently anatomical changes 
along vascular bundles are described. 


COURSE OF VASCULAR BUNDLES IN THE STEM 


Cinematographic analysis demonstrates that all vascular bundles behave 
essentially alike (Fic. 3). Major and minor bundles, with a we agoge 
transitional series, differ in relative position in the stem and in the 
number of internodes between their successive branchings. Any one leat is 
supplied by a larger number of minor and a smaller number of major 
bundles. 

From the base to the apex essentially all bundles maintain their indi- 
viduality and proceed indefinitely up the stem. Each of these vertical 


*Protoxylem is distinguished from metaxylem entirely by its position and the 
nature of its elements. Developmental differences are not considered here.

more frequently than the major bundles (Fic. 3, right). The overall 
course of the bundle is not a straight line. Each vertical bundle “moves” 
slowly towards the stem center. At intervals which vary according to its 
Status, the bundle is “pulled out” sharply towards the periphery. Major 
bundles extend well into the stem center, minor bundles are “pulled out” 
before they reach very far toward the stem center (Fic. 3, right). The 
fact that only relatively few bundles reach the stem center, but all

bundles are at one time or another in the peripheral region, results in 
a considerable crowding of the peripheral stem area. This crowding is 
accentuated by the large fibrous sheaths of the bundles in this area

A feature which cannot be indicated in FicurE 3 is the shallow helix 
exhibited by all bundles in the central, uncrowded part of the stem. 
Traced upwards, all central bundles rotate uniformly in a clockwise 
direction, the steepness of the helix being such that each bundle rotates 
about 1% of the stem circumference during a distance of about 15 cm. 
This helical path had been indicated by several earlier workers (e.g., 
Meneghini, 1836; Niageli, 1858), but irregularly and only for single 
bundles. Ciné analysis shows it to be a uniform property of all bundles. 
It is quite obvious that if the distance between two successive leaf 
contacts of the same (major) vertical bundle is a little over 30 cm. this 
twisting brings the higher contact to the side of the stem opposite that 
which bears the lower contact (cf. Mirbel’s diagram, Fic. 1B). If the 
path is still longer, the bundle may actually return to the original side 
of the stem. Monoyer’s diagram of the upper part of the stem of Are- 
castrum (Fic. 2, right) may be simply the expression of either longer 
distances between leaf-trace intervals and/or a steeper helix. 


DETAILS OF VASCULAR BUNDLE ANATOMY 


FicurE 5 shows three bundles drawn to scale, a major, a minor, and 
an intermediate one. It can be seen that the three traces enter the leaf 
at different angles. Therefore there is no distinct nodal plexus. 

During the oblique outward curve, a bundle forks repeatedly (Fics. 3, 
left; 6, 10, 11). The protoxylem-containing branch goes into the leaf as 
the leaf trace, the metaxylem-containing branches become respectively 


bundles. These four types of branches are discussed in the following 
paragraphs. 

Leaf trace. This originates by gradual transformation of the vertical 
bundle in the following way. Following any vertical bundle upward in 
the stem, at a point about 10 cm. below the next leaf contact, the first 
evidence of protoxylem is reached (position 3 in Fic. 3). From this 
point upward the amount of protoxylem increases continuously, The 
bundle then reaches its maximum size (position 4, Fic. 3), turns sharply 
toward the stem periphery and breaks up into several branches. The 
whole of the metaxylem, but normally none of the protoxylem, passes 
into these branches. The protoxylem-containing bundle is the direct 
continuation of the vertical bundle and goes into the leaf as the leaf 
trace. This means that there is no continuity of metaxylem between stem 
and leaf. The leaf is irrigated solely by protoxylem.* 

Vertical bundle. Ordinarily, the vertical bundle is the first branch 
to break off the leaf trace, shortly above the sharp outward turn. It 
then follows the leaf trace and near the stem periphery abruptly turns 
upward and continues its course up the stem, repeating the cycle (Fics. 
3-6) 


In most cases a single vertical bundle arises from a trace plexus. Oc-

(see text p. 173). This figure represents stages 4~7 of FIG. 3. 

casionally, however, none of the branches develops into a vertical bundle, 

in yet other cases two or even three vertical bundles may arise. This 

emphasizes the dynamic flexibility of the palm stem: the total number 

of bundles does not have to be exactly the same along the stem; in fact,

but also protoxylem. This indicates that the distance to its next higher 
The very small fibrous bundles in the cortical area (Fic. 7) are vertical 
bundles from minor leaf traces. They become smaller, ‘“move” towar s 
the stem periphery (rather than towards the center) and end blindly 
further up the stem. 


Bridge bundles. From each departing leaf trace, two to six bundles 
branch off and connect to vertical bundles in the neighborhood (Fic. 6). 





[voL. 46 


1965] ZIMMERMANN & TOMLINSON, RHAPIS EXCELSA 173 


Bridges are short, the longest one measured 4.5 mm. Occasionally they 
are so short that leaf trace and vertical bundle appear to fuse directly 
(Fic. 10). Bridges are always oriented obliquely upwards in the same 
way, so that the end of the bridge attached to the leaf trace is below 
the end attached to the vertical bundle. 

Bridge bundles normally come directly off the leaf trace, but they 
also may break off a satellite bundle or even the vertical bundle. Oc- 
casionally a single bridge bundle breaks up into two branches which then 
connect to two vertical bundles (Fic. 6 

Physiologically, bridge bundles not only provide vertical vascular con- 
tinuity via other vertical bundles, but they also provide extensive cross 
connections. Injection experiments in which dyes are introduced via 
petiole, root, or bore-hole in the stem, illustrate these lateral interconnec- 


tinuity of individual vessels. Vessels are of limited length and overlap 
within any one bundle, just as they do within the xylem of a diffuse- 
porous dicotyledonous tree. 

Satellite bundles. Several satellites branch from larger leaf traces in 
the region of bridge production (Fics. 3, left; 6, 11). Major traces 
produce up to 10 or more satellites; minor traces produce fewer or none, 
according to their size. Satellites accompany the trace to the periphery 
of the central cylinder. Some may “rotate” around the parent leaf trace 
and, in addition, may be inverted temporarily. They retain their in- 
dividuality but may become temporarily enclosed within the fibrous 
sheath of the parent leaf trace or a nearby vertical bundle without making 
vascular connection. Ultimately they form a “halo” around the leaf 
trace (Fic. 3, position 6; Fic. 9). Immediately below the leaf base they 
turn abruptly and tangentially, and enter the inflorescence rudiment. It 
is obvious that satellites are best developed if a fully developed inflores- 
cence is (or was) present. However, even inflorescences which had aborted 
very early in their development and are macroscopically not visible can be 
detected by their satellites, even in the lower “vegetative” part of the 
aérial stem (Fic. 8). 

With a good deal of experience, one can often easily distinguish, in 
a single transverse section, vertical bundle, satellites, and bridges. How- 
ever, this is not always possible, and one must follow the bundles up- 
ward in order to differentiate with certainty between the three types of 
branches that come off the leaf trace. One cannot help getting the im- 
pression that the three types, vertical bundles, satellites, and bridges, 
are developmentally equivalent. This problem will undoubtedly be met 
again, and hopefully be solved, when the apex is analyzed. 


COMPARISON OF RHAPIS WITH OTHER MONOCOTYLEDONS 


Our study of Rhapis has been carried out conjointly with the examina- 
tion of a number of larger palms. The reason for this is quite obvious. 


174 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Our findings differ so fundamentally from the “classical” diagrams (cf. 
Fics. 1 and 3) that the question arose as to whether we were dealing 
with an unusual object. Comparative studies have shown, however, that 
this is not the case. Whatever we have studied in other species has 
corresponded to Rhapis, although a great deal of work still remains to 
be done. We are now in a position to do it with the cinematographic 
method. 

Literature search has revealed that the actual observations of former 
botanists do not differ from our findings. The way in which these early 
workers put together diagrams by extrapolation and inference proved 
misleading. Interestingly enough, good observers like Von Mohl, Karsten, 
etc. describe the limits of their work precisely. Distortions arose by the 
inaccurate citation of older authors, by frequent re-drawing of diagrams, 
and by the failure to distinguish what was observed from what was in- 
ferred. 

Von Mohl’s original diagrams (1824) were correct but incomplete. 
Those showing the blind ending of bundles in a basipetal direction (Fig. 
VIII.2 in Tomlinson, 1961, p. 362) can be re-interpreted by assuming 
that Von Mohl’s upper series were of a major bundle (Tomlinson’s Figs. 
2a-f) and the lower series were of a minor bundle (Tomlinson’s Figs. 2g- 
i). This is very possible because Von Mohl merely drew a series of 
bundles from a single section and referred them to a hypothetical scheme. 
It was only subsequently (Von Mohl, 1849) that he considered the pos- 
sibility of bundle fusions. This hypothetical suggestion was seized upon 
by later workers and incorporated in their diagrams (e.g., De Bary, 1877; 
our Fic. 1E). Branner (1884) is the only nineteenth century worker 
who fully understood the continuity of vascular bundles, simply because 
he was able to examine a great deal of material at first hand. He dis- 
covered that the continuity of vertical bundles was only evident when 
the apical regions were examined. Macrodissection suggested the blind 
ending of bundles because connections are tenuous and easily broken in 
mature parts of the stem. It is a remarkable feature of botanical history 
that Branner’s very accurate work based on the careful examination of 
many palms in the field has been entirely overlooked in favor of wholly 
hypothetical schemes proposed by authors who had little opportunity of 
examining the problem at first hand. 

While one of us (M.H.Z.) is interested in the vascular anatomy of 
palms from the point of view of long-distance translocation, the other 
(P.B.T.) approaches the subject as a systematic anatomist. The un- 
ravelling of the palm stem via Rhapis has given a much sounder theoretical 
background for an appreciation of certain features tentatively proposed 
as diagnostically significant (Tomlinson, 1961; cf. also Stenzel, 1904, 
where the important problem of identifying fossil palm stems is discussed 
in detail). Palms have been subdivided into three main categories de- 
pendent on the presence, in any small sample of the stem, of a majority 
of vascular bundles with either one, or two, or many vessels. A multi- 


1965] ZIMMERMANN & TOMLINSON, RHAPIS EXCELSA 175 


dimensional understanding of the palm stem explains this variability. 
We have seen in Rhapis that these three conditions represent successive 
stages repeated in the same sequence in all bundles over and over again. 
In Rhapis all bundles, traced from below upward and beginning a little 
above a leaf contact, show initially (Fie. 3, stage 1) one metaxylem vessel, 
except for areas in which two vessels within one bundle overlap, for 
example in bridge contacts. Continuing upward, however, the bundle 
then shows two vessels separated by a parenchymatous isthmus (some- 
what below stage 4, Fic. 3). Finally (stages 4 and 5), prior and during 
the breaking up of the leaf-trace plexus, many metaxylem vessels are 
present. This increase in the number of vessels upward along a single 
bundle goes parallel with the increase in the amount of protoxylem. 

Diagnostic significance can only be attached to a comparison of bundles 
of the same stage (preferably stage 1) of two species. Thus Rhapis, as 
well as Ancistrophyllum, Areca, Borassus, etc. (Tomlinson, 1961, p. 336) 
can be referred to as ‘‘one-vessel palms.” ‘‘Two-vessel palms” can be 
recognized by protoxylem-free bundles which contain two vessels separated 
by a parenchymatous isthmus which indicates that the vessels are not 
merely overlapping ends. There may even be ‘“many-vessel palms,” but 
with the present state of our knowledge comment is not justified. 

One great danger of using this difference in number of vessels per 
vascular bundle (of the stage 1) as a diagnostic feature lies in being 
satisfied that a small region of the stem is an adequate sample of the 
whole. In palms, there are considerable quantitative changes from base 
to apex of a single axis. It is quite conceivable that the same stem could 
be a ‘“‘one-vessel’”’ type basally, yet ‘“‘two-vessel”’ distally. 

The genus Rhapis cannot yet be compared easily with monocotyledons 
like Zea (e.g., Kumazawa, 1961) or Tradescantia (Scott and Priestley, 
1925) which have a plexus of vascular tissue at each node. Non-nodal 
monocotyledons, however, may be similar, although few of these have 
been described in sufficient detail to merit comparison. An exception is 
Alstroemeria aurantiaca (Amaryllidaceae) analyzed by Priestley, Scott 
and Gillett (1935). This shows some of the basic features of the Rhapis 
type. Median leaf traces in Alstroemeria are derived from continuous 
vertical bundles, although this is not obvious because forking occurs many 
internodes below the node of exsertion. Forking of bundles many nodes 
below the level of their exsertion as leaf traces is illustrated in Falken- 
berg’s diagrams of several monocotyledons intended as representative of 
the “palm type.” But we know that the one palm (Chamaedorea) which 
Falkenberg claimed to have studied was analyzed incorrectly. We feel 
justified in being a little suspicious of Falkenberg’s diagrams. Rhapis 
still has to be analyzed in terms of developmental physiology in the manner 
of Priestley and his associates. No doubt in the future many other 
monocotyledonous shoots will be better understood with the Rhapis stem

SUMMARY 


The vascular anatomy of the mature, vegetative aérial axis of Rhapis 
excelsa (Thunb.) Henry is analyzed quantitatively by a cinematographic 
method. This involves photographing, frame by frame, either sequentially 
cut surfaces or serial sections stained and mounted permanently. The 
resulting film is analyzed in a data analyzer. All vascular bundles have 
essentially the same course and construction. In the uncrowded inner 
part of the stem they describe a uniform shallow helix continuously 
through the stem as vertical bundles, tending always toward the center 
of the stem. At intervals each turns sharply toward a leaf insertion and 
at the same time breaks up into several branches. The leaf trace proceeds 
into the leaf, satellite bundles go into the inflorescence, bridge bundles 


are minor, intermediate, and major bundles, the last reach farthest into 
the stem center and have the longest distances between successive leaf 
contacts. 


ACKNOWLEDGMENTS 


Routine serial sectioning on which this analysis is based was carried 
out by Lesley Jackson, Vroni Oswald, and Gabriel A. Vargo. We are 
indebted to them for their patience and perseverance with this tedious 
task. 

The generosity of Mrs. A. R. Jennings, who permitted unlimited access 
to the Coconut Grove Palmetum for supplementary experiments, is grate- 
fully appreciated.

STUDIES IN ALYSSUM: NEAR EASTERN 
REPRESENTATIVES AND THEIR ALLIES, II. 
SECTION MENIOCUS AND SECTION PSILONEMA 


T. R. DuDLEY 


A SYSTEMATIC SURVEY OF the genus Alyssum has long been needed, 
not only because it is the largest cruciferous genus in Turkey, accounting 
for approximately one fifth of the taxa of the Cruciferae in that area, 
but also because it has been the subject of some revisionary work (at 
least in the perennial species of sections ALyssum and OpONTARRHENA). 
The very extensive, and mostly unidentified Near Eastern collections of 
P. H. Davis, A. Huber-Morath, and K. H. Rechinger have added impetus 
to the need for a reassessment of morphological characters and variation, 
and a more stable definition of the specific and infraspecific taxa. 

Previously, the only practical procedure for identifying Alyssum was 
to compare and contrast individual specimens with “correctly determined’ 
herbarium material. The lack of conformity in treatments because of 


hierarchies and extreme “splitting” of Fenzl in Tchihatcheff (1860), J. 
Baumgartner (1907-1911), and E. J. Nydrady (1926-1949). Taxa such 
as Alyssum linifolium, A. alyssoides, A. minus, A. minutum, A. montanum, 
A. sibiricum, A. tortuosum, A. murale, etc., having very wide geographical 
distributions are subject to considerable morphological variation within 
and between populations, as well as between individuals. 

With the exception of section TETRADENIA, whose component species 
are not known to occur in Turkey, and section PstLtoneMA which is repre- 
sented in Turkey only by the widespread Alyssum dasycarpum (also 
possibly A. alyssoides, cf. page 199), more species (eighty-eight) and 
endemic species (forty-nine) are found in Turkey than in any other land 
area of comparable size. Of the seven species assigned to section MENI- 
ocus, six occur in Turkey, and of these three are endemics. These 
endemics (A. blepharocarpum, A. stylare and A. huetii) are characterized 
by a unique fruit indumentum of setae, found only in section MENtocus. 
The other species of this section having the same type of fruit indumentum 
is A. heterotrichum from Iran, Afghanistan, and a part of Kazakh S. S. R. 
The remaining three species of section MENIocUS are glabrous-fruited. 
Of these, A. aureum and A. meniocoides have continuous distributions from 
southern Turkey to Syria, Lebanon, Palestine, Iraq, and Tran, while 
A. linifolium is one of the most widespread in the genus, extending from 
England (where it was probably introduced) throughout Europe and 
Asia, and east to India. It is probable that as Turkey has the largest 


182 JOURNAL OF THE ARNOLD ARBORETUM [ VOL. 46 


representation of species and endemics of section MrENiocus, it has been 
the center of speciation for that section. Certainly, Turkey is the current 
center of diversity. On the other hand, this is not true for section 
PsILONEMA, Of which only one species is known definitely to occur in 
Turkey. Whereas Alyssum granatense is found only in Spain and North 
Africa, A. damascenum and A. homalocarpum, although both Oriental 
species, are to be considered as Saharo-Sindian elements, and are not 
known from Turkey. 

The widespread taxa Alyssum linifolium of section MeENtocus, and 
A. alyssoides and A. dasycarpum of section PstLoNeMa are characterized 
by a wide range of environmental tolerance. Such species as A. aureum 
and A. meniocoides which have more or less continuous distributions from 
Turkey into adjacent regions and are steppe-inhabiting or Irano-Turanian 
elements, are relatively limited by particular habitat preferences. This 
is also true for the Turkish endemics of section MENtocus, which although 
found in spatially open habitats, are characterized by a narrow range of 
environmental tolerance. All species of sections MENtIocus and PsILONEMA 
are essentially calcicolous. This feature is particularly pronounced in 
Turkey where the species of section MrENnr1ocus are usually found on 
calcareous substrates, and is correlated with their preference for the steppe, 
the soils of which are primarily of limestone structure. The very wide- 
spread A. linifolium and A. dasycarpum attain their maximum develop- 
ment in the calcareous steppe and serpentine mountain screes, but tolerate 
and are relatively abundant in the saline steppe. Similarly, A. blepharo- 
carpum is known to occur in the salt impregnated portions of the steppe 
which surrounds many lakes of the Turkish interior. 

In this and succeeding papers, the strictly European or Asiatic species, 
which are most closely allied to those occurring in Turkey are included 
in the keys, and are treated systematically. However, these studies of 
Alyssum must be regarded primarily as a systematic revision of the 
Turkish species. 

To assist in interpretation of the keys and descriptions, in this paper 
and in those to come, three plates showing the morphological diversity 
of petals, filaments, fruits, and trichomes are included. These plates illus- 
trate only the major types of diversity of these structures throughout the 
genus. Prates II and III show some of the diversity of the distinguishing 
floral and fruit characters. PLATE IV illustrates basic hair types which 
comprise the indumentum. These types are arranged more or less in a 
progressional sequence, from the simplest to the most complex. This 
does not imply, however, that one type necessarily evolved directly from 
any other. Many of the fruits pictured in Prater III are normally cov- 
ered with a characteristic indumentum (Fics. a, c—g, j-o). This indumen- 
tum has been omitted in order that the fruit shape and configuration not 
be obscured. I am grateful to Dr. P. H. Davis, University Department 
of Botany, Edinburgh, Scotland, for permitting the use of these three 
plates, which were drawn for the forthcoming Flora of Turkey by Mrs. 
A. Dyer. 


1965 | DUDLEY, STUDIES IN ALYSSUM 183 


Included in this paper are keys to all currently recognized species as- 
signed to sections MENrocus and PstroneMa. In the main, all specimens 
seen have been cited, with the exception of the very widespread and 
common taxa, such as Alyssum linifolium or A. alyssoides. The specimen 
citations of these two species, as examples, from many areas in Europe 
could easily number several hundreds. In such cases I have cited only 
a few representative specimens; in most large herbaria, however, there 
will be found abundant additional material. Although I have omitted 
specimen citations for common European species, the citations of speci- 
mens of these taxa from the countries of the Near East are as complete 
as possible since floristic studies of the Near East are still in the explora- 
tive stages. This policy will be followed also in further papers on Alyssum. 

The abbreviations for herbaria given by Lanjouw and Stafleu (eds.), 
Index Herbariorum, ed. 5 (Regnum Vegetabile 31. 1964) are used in this 
paper. Several not listed in an earlier paper (Jour. Arnold Arb. 45: 58, 
60. 1964) are given here.

Alyssum linifolium is one of the most widespread species in the genus, 
and is quite variable in the size of its leaves and fruits, and in its stature. 
However, with the exception of the variety which follows (var. teherani- 
cum), the minor variations do not warrant nomenclatural recognition. 
One interesting variation occurs on plants (e.g. Davis 18691 and Dudley, 
D. 35928) growing in extreme saline habitats. The leaves of these plants 
are very narrow and conduplicate, resembling those of A. meniocoides. 
This character, however, is not constant, for the plants assume a normal 
appearance immediately outside the salt areas. nor 

The closest allies of Alyssum linifolium are A. meniocoides and A. 
aureum, both of section Mrentocus. From these, A. linifolium may be 
easily distinguished by its wingless seeds, much shorter styles, and smaller 
floral parts.

Professor Zohary (Palest. Jour. Bot. Jer. ser. 2(2/3): 162. 1941) 
maintains that Alyssum minimum L. (Sp. Pl. 2: 651. 1753) is the correct 
binomial for this species, and that A. linifolium is a synonym. Examina- 
tion of Linnaeus’s specimen of A. minimum (LINN. 828:8) proves with- 
out any doubt that this is not the case; A. minimum L. can only be treated 
as a synonym of Lobularia maritima (L.) Desv. (Basionym: Clypeola 
maritima L. Sp. Pl. 2: 652. 1753). A. minimum sensu Willd. (Willd. Linn. 
Sp. Pl. ed. 4. 3(1): 464. 1800) clearly is not the same taxon as A. mini- 
mum L., but may be identified rather as A. desertorum Stapf.

The differential characters of Alyssum linifolium var. teheranicum are 
consistent in small and scattered populations throughout the southeastern 
range of the species. The type specimens of var. teheranicum are morpho- 
logically identical to those of A. cupreum, the latter name is, therefore, 
placed in synonymy. Bornmiiller used yet another varietal name for this 
taxon in exsiccatae, but without a Latin description. This epithet re- 
ferred to the dense, metallic-colored indumentum.

and more or less resemble those of A. aureum. In all other respects, 
however, these plants possess all the other characters of A. meniocoides. 
Collectors have frequently confused A. meniocoides with A. linifolium, 
which occurs commonly throughout the same geographical areas, but the 
former has winged seeds, longer styles, larger floral parts, and generally 
narrower and conduplicate leaves.

The species Meniocus pleiospermum and M. grandiflorus are based on 
the same type material (Kotschy 27) as M. aureus, the basionym of 
Alyssum aureum, The other syntype of VM. grandiflorus pital 4100) is 
correctly referred to Alyssum linifolium var. teheranicu 

Zohary (Pal. Jour. Bot. Jer. Ser. 2(2/3): 162. 1941) ener that 
the differences between A. aureum and A. meniocoides were very slight, 
and recombined A. aureum as a variety of the latter species. A. aureum 
may be distinguished from A. meniocoides by its considerably longer 
styles, larger and retuse or bilobed petals, larger fruit, and usually flat 
and wider leaves. Although the distinction in petal size and leaf form 
occasionally breaks down (cf. note under A. meniocoides), the much longer 
styles, and the always retuse or bilobed petals remain diagnostic for A. 
aureum. Furthermore, these species retain their identity in regions of 
overlap, and they clearly have different flowering times. 

The inclusion of A. aureum by Parsa (FI. Iran 1: 747. fig. 622. 1952) 
is probably an error. With the exception of this reference, A. aureum 
has not been recorded from Iran, and no Iranian specimens have been 
seen at Kew, upon whose collections Parsa based his work. These ma- 
terials, and Parsa’s illustration lead me to conclude that A. aureum sensu 
Parsa is, in fact, A. minutum.

The closest ally to Alyssum huetii in Turkey is probably A. stylare, 
which is also an Anatolian endemic. It may be distinguished from A. 
stylare by its shorter and stouter styles, smaller floral parts, and sparser 
fruit indumentum of shorter and slender setae, and — It is also 
Closely related to A. heterotrichum from Iran and Rus 

The fact that the vast area of east-central eos has been little

Among the species of section MENtocus, Alyssum stylare has the longest 
styles, and the densest fruit indumentum which is composed of tubercu- 
late, simple (occasionally bi- or trifurcate) setae to 1 mm. long. The 
furcation of the hairs on the fruit is unique in the section. 

Although Alyssum stylare is sympatric in the eastern part of its range 
with A. blepharocarpum, it always has larger and obtuse fruits, deeply 
bifid petals, and wingless seeds. Its larger flowers, denser fruit indumen- 
tum, larger and broader leaves, stricter habit, and much longer, circinate 
inflorescences distinguish it from A, huetii

The type specimens of Alyssum bungei do not deviate in any characters 
from material of A. hketerotrichum, and accordingly the name, A. bunget, 
should be treated as a synonym of A. heterotrichum. Boissier considered 
A. bungei to be the only annual species of section ODONTARRHENA, but he 
commented that this was an artificial placement based entirely on his 
observation of its uniovulate fruit locules. I have examined fruits from 
the type material of A. bungei and have found that the fruit locules con- 
sistently contain four or five ovules. It is true, however, that only one of 
these ovules develops into a mature seed, while the others abort. In this 
case, the fruits are one-seeded and the aborted ovules are visible under 
magnification. A. heterotrichum is the only species in section MENIOCUS 
having setae on the fruits, and an entirely extra-Anatolian distribution.

the wider wings having acute or denticulate teeth (0.5 mm. long), never 
exceeding the anthers. Short filaments 1.5-2 mm. long with connate, 
lanceolate or denticulate appendages, 1 or more the length of filaments. 
Fruits ovate-orbicular, usually truncate, 3.5-4.5(-5) > 2-3(-3.8) mm., 
papillose, or smooth, and always with sparse, short, slender tuberculate 

setae, at least on margins. Styles slender, (0.7—) 1-2 mm. long. Seeds

The nomenclatural confusion between Alyssum alyssoides and A. minus 
(A. campestre sensu multo auct.) has been discussed in an earlier paper 
(Jour. Arnold Arb. 45: 63-65. 1964). Although these two species are 
assigned to different sections, to section PsILONEMA and section ALYSSUM 
respectively, they are frequently confused. The sepals of A. alyssoides 
are always persistent, its filaments are very slender, edentate and un- 
appendaged, its nectaries are peg-like and erect, and its styles are usually 
glabrous. In addition, the symmetrically inflated fruits of A. alyssoides 
are generally smaller, and the easily displaced indumentum on the fruits 
is composed of shorter-rayed stellate hairs. 

Although specimens of A. alyssoides have been recorded from Turkey, 
I have not seen any Turkish material. Certainly its presence in Anatolia 
needs confirmation. It seems safe, however, to assume that the records 
from the Armenian Highlands in eastern Turkey are correct. It is well 
known from the Caucasus, and its presence in Armenia would be an 
expected pattern of distribution. Throughout the Levant, A. alyssoides 
is very rare (cf. Bornmiiller, Bot. Centralbl. Beih. 38: 479. 1921). For 
the most part, the Caucasian, Turkish and Afghanistan specimens of 
A. alyssoides are from higher altitudes (e.g. Hedge & Wendelbo 3146, 
Afghanistan at 2800 m.) than are those normally found in Europe. From 
the paucity of records and specimens from the Levant it is assumed that 
this species has been unable to colonize and spread in the ruderal and 
disturbed types of environments, with which it is normally associated 
throughout much of Europe. Rather, it is apparently confined to isolate 
pockets in the mountains. Conversely, it is interesting to note that it has 
adapted well to the ruderal habitats of North America, and accordingly 
seems to be commoner than in Turkey. 

As a common European species A. alyssoides has long been subjected to 
a very critical examination by numerous workers, many of whom (i.e. 
Jordan, Sennen, Nyarady, Prodan, etc.) have contributed to the literature 
approximately thirty taxonomic segregates, mostly of varietal or forma 
rank, and almost twice as many recombinations. As it would not be in the 
interests of brevity or clarity to cite all of those minor synonyms, I have 
referred only to those species of Jordan which subsequently have been 
recombined many times as subspecies, varieties, formae, and even sub- 
formae. This species is very polymorphic with respect to plant height, 
stem length, leaf size, leaf, fruit and sepal indumentum density, and 
raceme length. The many segregates, excluding var. depressum which 
follows, have been based chiefly on single character deviations, which are 
very flexible and unstable according to the varying environmental pres- 
sures. Many of the characters rarely occur on a population basis, and 
examination of the type specimens has revealed that, more often than not, 


ey ee ren ee tea 


1965 | DUDLEY, STUDIES IN ALYSSUM 203 


the characters are not constant on individual plants. When the morpho- 
logical variation of A. alyssoides is considered throughout the whole range 
of distribution, characters such as density of fruit indumentum do not 
appear to have the stability essential for taxonomic recognition. The one 
exception is var. depressum which forms small and scattered, but pheno- 
typically stable populations in Romania, Hungary, Bulgaria, Greece, and 
Crete.

Alyssum damascenum is sometimes confused with A. minus, a weedy 
species in section ALyssumM common throughout most of Europe and the 
Near East, because of a resemblance in fruit shape and indumentum. The 
filaments of A. damascenum, however, are always wingless, edentate, and 
unappendaged, while those of A. minus are widely winged, appendaged, 
and usually dentate. A. contemptum from Palestine, another species of 
section ALyssum is sometimes confused with 4. damascenum due to the 
annual, low growing habit. A. contemptum has widely winged toothed 
and appendaged filaments, small globose nectaries, entire or merely 
emarginate petals, and elliptic fruits whose valves are very asymmetri- 
cally inflated, similar to those of A. szowitsianum. The fruits of A. 
damascenum are orbicular with more or less equally inflated valves, its 
nectaries are erect and peg-like, and its petals are deeply bifid. 

Zohary and Fahn (Pal. Jour. Bot. Jer. ser. 2(2/3): 130. 1941) and 
Zohary (op. cit. 161) assign A. damascenum to the group of annual species 
in section ALyssum (including A. marginatum and A. szowitsianum) 
characterized by a unique pedicel anatomy associated with the specialized 
hygrochastic method of seed dispersal. However, in addition to possessing 
the diagnostic features of section Psttonema, A. damascenum has 4 
pedicel anatomy, which (as originally noticed by Zohary & Fahn) is 
different from that of the other species mentioned. These facts suggest 
that, although the annual species of section PsttoNEMA and section 


"~ 


a i cel 


1965 | DUDLEY, STUDIES IN ALYSSUM 205 


ALyssuM are closely allied, the phenomenon of hygrochastic dispersal 
has developed convergently within the two sections.

persistent sepals is A. strigosum (sect. ALyssum), which is frequently 
confused with A. granatense because of a similarity in habit and facies. 
The major differences between them are detailed in the following table:

From Alyssum alyssoides, the closest ally to A. granatense in section 
PsILoneMaA, the latter is distinguished by its always larger floral parts, 
larger fruits, globose and reduced nectaries, erect and adpressed position 
of the pedicels, and the dimorphic fruit indumentum.

210 JOURNAL OF THE ARNOLD ARBORETUM [ VOL. 46 


From all the other oriental species in section PstLoNEMA, Alyssum 
dasycarpum may be distinguished by the dimorphic and strigose fruit 
indumentum, longer and basally dilated styles, and wingless seeds. The 
always orbicular fruits of A. granatense from the Iberian Peninsula and 
North Africa are at least twice the size of those of A. dasycarpum. Also, 
the tuberculate hairs on the fruits of the western European species are 
sparser and longer, resembling more those of A. hirsutum (sect. ALYSSUM). 
Alyssum strigosum (sect. ALyssuM) is sometimes confused with A. dasy- 
carpum because of the similar dimorphic fruit indumentum. However, the 
fruits of A. strigosum are larger and are covered with longer furcate hairs. 
In addition, the winged, dentate and appendaged filaments, larger floral 
parts, winged seeds, and widely divergent pedicels are diagnostic for 
A. strigosum. No specimens which have winged seeds have been found 
throughout the range of A. dasycarpum. A plausible explanation for the 
Ukranian A. dasycarpum var. pterospermum (Bordz. Bull. Jard. Bot. Kiev 
7-8: 17. 1928) is that unless the seeds are examined under magnification, 
the lighter colored and often translucent radicle may be misinterpreted 
as a wing formation.

This is the only glabrous-fruited representative of section PSILONEMA 
having deciduous sepals, and it is the only Alyssum with minute teeth 
towards the apices of the leaves. Rechinger (loc. cit.) notes and illustrates 
the papillose fruit margins of A. homalocarpum. This character, although 
rare in the genus, is not unique. A Greek endemic, A. euboeum (sect. 
OpONTARRHENA) also has fruits, the margins of which are papillose, 
especially towards the apices. The fruit size of A. homalocarpum varies 
considerably; the smallest measure circa 3 < 3 mm., and the largest 7 X 
7 mm., but without any apparent geographical pattern. None of the char- 
acters said to distinguish A. nomismocarpum from A. homalocarpum, i.., 
longer racemes, fragile stems, larger fruits, and shorter pedicels, indicates 
a satisfactory specific separation when the entire range of morphological 
variation is taken into consideration. Similarly, A. musili and A. horebicum 
do not possess sufficient discontinuities to separate them from A. homalo- 
carpum.

THE GENERA OF VALERIANACEAE AND DIPSACACEAE 
IN THE SOUTHEASTERN UNITED STATES * 


I. K. FERGUSON

VALERIAN FAMILY) 


Annual or perennial herbs, sometimes woody at base. Leaves in basal 
rosettes or opposite, pinnately divided or entire, exstipulate, the bases 
often arene ih Inflorescence a monochasium, thyrse, or many-flowered 
compound dichasial cyme, sometimes condensed and capitate, bracteate 
and shee goreene rer Flowers irregular or almost regular, bi- 
sexual or unisexual. Calyx obsolete or developing late and becoming con- 
spicuous only in fruit, annular [or toothed], adnate to ovary. Corolla 

4 


[bilabiate]. Stamens epipetalous and alternate with the corolla lobes, vary- 
ing in number, usually 3 in our genera [1, 2, 3, or 4]; anthers versatile, 
2- or 4-lobed, 4-locular, introrse, dehiscing longitudinally: pollen tricolpate, 
echinate. Gynoecium syncarpous, ovary inferior, 3-locular, with two 

locules usually suppressed and one fertile, with a solitary, pendulous, an- 

atropous ovule; style 1, stigma simple or lobed. Fruit dry, indehiscent, the 
calyx often developing into a winged, awned, or plumose pappus. Seed 1; 
endosperm absent; embryo large, straight, the cotyledons oblong, the 
radicle superior. TypE GENUs: Valeriana L. 


A family of about ten genera and 370-400 species, widely distributed 
but occurring mainly in the North Temperate regions and absent from 
Australasia; three ogi native and one introduced in North America; 
two genera in our a

distinguished by the 3-locular ovary (one locule fertile), cymose inflores- 
cences, and seeds without endosperm. The family also has affinities with 
the Caprifoliaceae and Rubiaceae. 

Members of the family often have a very characteristic unpleasant odor. 
Volatile oils occurring mainly in the root and rhizome have been investi- 
gated extensively, especially in Valeriana. 

The cytogenetics of the family have not been very fully investigated, 
although chromosome numbers for some species of Valeriana (21 species 
of 300) and Valerianella (11 species of 60) are available. However, only 
a few chromosome counts are reported for four additional genera: Centran- 
thus, 2n = 14, 32 (three species); Fedia, 2n = 32 (one species) ; Patrina, 
2n = 22 (one species); and Astrephia, 2n = 32 (one species). 

The family is of little economic importance. A few members, among 
them Centranthus ruber (red valerian) and Valeriana officinalis (garden 
heliotrope or common valerian), are grown as ornamentals. The latter is 
used as a source of the drug “valerian.” Corn salad (Valerianella Locusta), 
as its name implies, is used in salads. Spikenard (Nardostachys Jatamanst) 
yields an oil which has been used in perfumery in the East.

sexual. Calyx inrolled in flower, enlarging and developing in fruit to form 
a pappus with short, sessile, patelliform, membranaceous limb and 5-15 
plumose awns [or the limb cupuliform and irregularly dentate]. Corolla 
funnelform or campanulate [salverform or rotate], the tube slightly sac- 
cate at the base [or straight], usually more or less hairy in the throat, 
5[3 or 4]-lobed. Stamens 3 [rarely 4], inserted toward the top of the 
corolla tube, usually exserted (but included in V. scandens); anthers 2- 
or 4-lobed. Stigma simple or 3-lobed; ovary 3-locular, with two locules 
suppressed and one fertile with a solitary ovule. Fruit a unilocular, com- 
pressed achene with 3 nerves on the outer and 1 on the inner surface. 
LeEcToTYPE SPEcIEs: Valeriana pyrenaica L.; see Britton & Brown, Illus. 
Fl. No. U. S. ed. 2. 3: 284. 1913. (Name Medieval Latin, from valere, 
to be strong; said also to be named for the Roman emperor Valerianus). 


A genus of about 300 species of Europe, Asia, Africa, and America, 
centered mainly in the temperate regions of the Northern Hemisphere and 
the mountains of South America; eleven species in the United States, two 
in our area. 

Of the seven sections recognized by Hock, six (Pseudiastrephia Hock, 
Hybocarpus Hock, Valerianopsis Wedd., Phyllactis Pers., Porteria Hook., 
and Aretiastrum DC.) are entirely South American and have been various- 
ly treated by different authors as distinct genera or as sections within 
Valeriana. The North American species belong to sect. VALERIANA 
(§ Euvaleriana Hock). Different authors have recognized a varying 
number of series within this section (cf. Héck, Meyer). 

The genus is well defined by the combination of perennial habit, three 
stamens, and inrolled calyx usually enlarging and forming a pappus on 
the one-locular fruit. It is probably most closely related to Valerianella 
and to Centranthus, which is distinguished by one stamen and spurred 
corolla. 

Valeriana scandens L., readily recognized by its climbing habit, occurs 
in Mexico, Central and South America, and the West Indies, northward in 
peninsular Florida to a shell-mound in Duval County. It seems likely that 
this species is a calciphile, but it does not appear to occur on the 
Florida Keys. It is placed by Meyer in the Sorbifoliae, a series distin- 
guished chiefly by included stamens and two-lobed anthers. Meyer recog- 
nizes two varieties (which some authors have treated as distinct species) : 
var. scandens, with tripartite leaves, and var. Candolleana (Gard.) Muell., 
with entire leaves. The widespread var. scandens occurs in Florida, but 
var. Candolleana occurs northward only to Hispaniola and Cuba. Inter- 
mediate specimens with both entire and tripartite leaves have been found, 
however, both in our area and elsewhere. Valeriana pauciflora Michx., 
distinguished by its long, funnelform corolla tube and stoloniferous habit, 
occurs from Pennsylvania to Illinois, Tennessee, and Virginia. It is placed 
in the series Officinales Hick, separated by the rhizomatous or stolonifer- 
ous roots and four-lobed anthers. 


222 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Sexual polymorphism occurs in the genus in several ways, the plants 
being completely hermaphrodite, polygamous, polygamodioecious, or di- 
oecious, with dioecism least common. The presence of unisexual as well as 
bisexual flowers is easily detected by the differential lengths of the corolla. 

The mode of pollination appears to be unknown but is probably ento- 
mophilous, Nectaries are reported to occur in the saccate base of the 
corolla tube. The occurrence of proterandry assures cross-pollination in 
bisexual flowers. 

e cytogenetics of Valeriana officinalis, 2n = 14, 28, 56, has been 
extensively investigated, but the cytology of the genus as a whole is not 
well known. Chromosome numbers of 2n = 14, 16, 18, 28, 32, 56, and 
64 have been reported.

A genus of temperate parts of the Northern Hemisphere, including about 
60 species in two sections; 19 in North America, ten in our area 

The shape, relative size of the sterile locules, and indumentum of the 
fruits are the most important characters used to distinguish the species. 
The indumentum of the plant and the shape of the bracts (rounded, 
pointed, or acuminate) are also important characters. Specimens with 
both fruit and flowers are necessary for the determination of species. 

Four species of sect. SPHONELLA Krok, marked by salverform corollas 
and strongly glandular fimbriate-serrulate bracts, occur in the southeastern 
United States. Valerianella Bushii Dyal and V. ozarkana Dyal are strictly 
calciphile and known only from Arkansas and Missouri, while V. Nuttallii 
(Torr. & Gray) Walp. and V. longiflora (Torr. & Gray) Walp. are known 
only from western Arkansas and eastern Oklahoma. The other six species 
of our area belong to sect. VALERIANELLA, with funnelform corolla and 
glabrous bracts with entire or ciliate margins. Valerianella Locusta (L.) 
Betcke (V. olitoria (L.) Poll., Valeriana Locusta L. a olitoria L.), 2n = 
14, an introduced European species widely scattered throughout our area, 
is readily recognized by the corky mass on the fertile locule of the fruit. 
Valerianella umbilicata (Sulliv.) Wood and V. patellaria (Sulliv.) Wood 
occur from North Carolina and Tennessee, northward to New York, Ohio, 
and Illinois. They are distinguished from the other species in the section 
by the breadth of the sterile locules in comparison with the fertile locule 
of the fruit. Valerianella intermedia Dyal, which ranges from Massachu- 
setts to Kentucky and Illinois, occurs in scattered localities in North and 
South Carolina, apparently as an introduction. It is closely related to 
V. radiata (L.) Dufr., a widespread, polymorphic species occurring 
throughout our area and extending to Pennsylvania, Kansas, and Texas. 
Valerianella Palmeri Dyal, occurring only in Arkansas, appears to be 
closely related to V. intermedia but is separated by its longer fruit with 
abortive sterile locules. 

Somie authors have thrown doubt on the validity of some of the species 
recognized in North America. Dempster has found dimorphism in the 
fruits of species of the closely related Plectritis and has revised the taxono- 


1965] FERGUSON, VALERIANACEAE AND DIPSACACEAE 225 


my of that genus. In view of this, the species pairs Valerianella Bushii— 
V. ozarkana and V. umbilicata—V. patellaria need further investigation, 
for in each pair the two sometimes grow together, show a similar, limited 
geographical distribution, and are distinguished by their fruits. 

There is a lack of cytological information relating to North American 
species of Valerianella. Chromosome numbers of 2n = 14, 16, 18, 32 have 
been reported for European and Asiatic species. The method of pollination 
appears to be unknown; insect visitors have been observed and self-pollina- 
tion reported to occur. 

Valerianella has affinities with Valeriana. It is very closely related to 
Fedia and Plectritis, and early authors treated these variously as one or 
more genera. More recent authors have treated Fedia as a monotypic 
Mediterranean genus distinguished by its irregular corolla, two stamens, 
and dimorphic fruits. Valerianella is separated from the predominantly 
western North American Plectritis by the typically 3-locular ovary, 3- 
lobed stigma, and dichotomously branched inflorescence vs. the 1-locular 
ovary, 2-lobed stigma, and capitate or interruptedly spicate inflorescence.

DIPSACACEAE A. L. de Jussieu, Gen. Pl. 194. 1789, “Dipsaceae,” nom. cons. 
(TEASEL FaMILy) 


Mostly perennial herbs, the flowers bisexual, irregular, with a calyx- 
like involucel of fused bracteoles, and borne in the axils of imbricate recep- 
tacular bracts, the calyx small [variable|, the corolla gamopetalous, 4[5|- 
lobed, the stamens 4 [5], inserted toward the top of the corolla tube, and 
the ovary inferior. TyPE GENUS: Dipsacus L. 


An Old World family of about eight to twelve genera and 250-300 
species, centered in the Mediterranean and Near East, extending to North 
Europe, East Asia, and South Africa. About ten species in the genera 
Dipsacus, Cephalaria, Scabiosa, Knautia, and Succisa are naturalized in 
North America; one species of Dipsacus occurs in our area. 

Dipsacaceae are placed in the Rubiales by most authors and appear 
to be a very natural family, with the exception of the isolated genus 
Morina, which some authors have placed in a separate family. Dipsacaceae 
have close affinities with Valerianaceae. The family is distinguished from 
Valerianaceae by the unilocular ovary and by the capitate inflorescence 
surrounded by an involucre of bracts, characters which suggest affinities 
with Compositae. 

Chromosome numbers of 2” = 10, 14, 16, 18, 20, 34, 36, 38, 42, 43, 
44, 46, 50, 54, and 64 have been reported. Ehrendorfer has suggested that 
the basic chromosome number of the family is x = 9 and that euploidy, 
aneuploidy on the diploid level, polyploidy followed by aneuploidy, gene-, 
chromosome-, and genome-mutations have been important in the evolution 
of Dipsacaceae. 

The variation in the receptacular bracts and the diverse development of 
the involucel and calyx are connected with fruit dispersal and give good 
characters for taxonomic division of the family into genera. 

e family is of little economic importance. A few genera are of horti- 
cultural interest, and Scabiosa is widely cultivated for its ornamental 
value.

tacular bract and surrounded by a 4-angled tubular involucel of fused 
bracteoles, which is grooved with a median rib and truncate at the apex, 
with an almost obsolete denticulate margin. Calyx cup-shaped, 4-angled, 
with a ciliate margin. Corolla imbricate, lobes often unequal. Stamens 4,

eral, entire; style filiform; ovary unilocular, ovule solitary, anatropous,

About 12 species of Europe, western Asia, and Africa, three naturalized 
in North America. Dipsacus fullonum L. (D. sylvestris Huds.) ,? 2n = 16, 
18, a native of Europe, is probably widespread and scattered throughout 
the United States, occurring sporadically in our area. Dipsacus fullonum 
has close affinities with D. sativus (L.) Schkuhr (D. fullonum auct. non 
L.), 2n = 16, 18, also a native of Europe, locally naturalized in the north- 
eastern United States. The involucral bracts curve upward in D. fullonum 
and the receptacular bracts end in a long straight spine, while in D. 
sativus the involucral bracts spread more or less horizontally and the 
receptacular bracts end in a stiff, recurved spine. Some authors have 
treated D. sativus as a subspecies of D. fullonum. The very different 
laciniate-leaved D. laciniatus L. is established in the northeastern United 


The genus is mainly a well-defined one recognized by the presence of 
stem prickles and spine-tipped bracts. It is most closely related to Cepha- 
laria, which is also distinguished from the rest of the family by chaffy 
receptacular bracts and a four-angled involucel. Grenier and Godron 
placed D. pilosus L. in Cephalaria, but few subsequent authors have 
adopted this treatment. 

The mode of flowering in the genus is characteristic, the flowers opening 
first about halfway up the head and developing in sequence both upward 
and downward. 

The species are separated on the basis of the leaves, which may be con- 
nate or stalked, entire or divided; the inflorescence, which may be oblong, 
ovate, or globose; and the involucral bracts, which may be linear-lanceo- 
late, subulate, keeled with spines on the margins and midrib, or narrowly 
triangular, shorter or longer than the inflorescence. 

* The application of the name Dipsacus fullonum L. will be discussed in the next 
issue of this Journal.

The ripened inflorescences of D. sativus, the fuller’s teasel, are used in 
fulling cloth (raising the nap), and the plants are grown to a limited ex- 
tent for this purpose. 

The flora and fauna of the rain water caught by the connate leaf bases 
have been studied more or less extensively, but most biological aspects 
of the genus have been neglected. 

Chromosome numbers of 2” = 16, 18, 36 have been reported.

A PRELIMINARY REPORT ON FUNIFERA 


Lorin I. NEVLING, JR. 


THE EARLIEST RECORDED INFORMATION concerning the plants now recog- 
nized as members of the thymelaeaceous genus Funifera C. A. Mey. was 
published in 1820 (Atti Soc. Ital. Sci. Modena 18: 391), by the Italian 
botanist Raddi, In that publication, by means of a rather sophisticated 
and complete description, Raddi defined a new Brazilian species of Daphne, 
D. brasiliensis (to be transferred below to Funifera). In nearly a century 
and a half which has since elapsed, our knowledge of this and related 
species has not increased much; the chief contribution being descriptions 
of a few additional species. 

At the suggestion of Mr. Guido Pabst, Director of Herbarium Bradean- 
um, I started what was intended to be a comprehensive revision of the 
genus Funifera. However, the poor quality of most of the existing collec- 
tions (i.e., flowers and fruits lacking from most of the sheets) has frus- 
trated such a project. I hoped the difficulties would be at least partially 
overcome when I had a large suite of specimens assembled. Since, how- 
ever, the additional material was not very satisfactory I am presenting 
as a report the information now available, hoping it may serve as an out- 
line for field work and eventual new collections which will make possible 
a precise and detailed study. 

The species of the genus Funifera are not conspicuous components of 
the vegetation in the areas of Brazil where they grow; nor are they of great 
economic importance even at the local level. They are intriguing because 
so little is known of their geographic and ecologic distribution, their anato- 
my, and their morphology. In addition, the medicinal potential of these 
plants found in references from folk-medicine, has both practical and 
theoretical application in modern phytochemistry. 

Various properties attributed to plants of the genus Funifera are similar 
to those ascribed to other genera of the Thymelaeaceae. The tough cortical 
fibers of Funifera are employed as cordage (Penna, 1946) a common prac- 
tice in related genera of the family throughout the geographic distribution. 
The fibers of the American genera are never used in paper making, this 
use being restricted entirely to the Old World members of the family. 
A decoction of the macerated bark of Funifera is used externally as 4 
vesicant (Dragendorff, p. 204. 1898) in the same manner as that of 
Daphne mezereum L. of Europe. If accidentally ingested the decoction is 
especially caustic to the mucous membrane of the mouth. Other American 
Thymelaeaceae known to have a similar vesicating effect are Daphnopsis 
(one species has the common name “Burn Nose”), Dirca, and Ovidia. 

A decoction of the leaves of Funifera may be used internally as an 


1965] NEVLING, REPORT ON FUNIFERA 233 


emetic or cathartic according to Hoehne (pp. 204, 205. 1939). Similar 
results may be obtained also from the New World genera Daphnopsis, 
Dirca, Lagetta, Lasiadenia, and Ovidia. Based on a very limited number 
of reports, in Daphnopsis, Dirca, and Ovidia, such a decoction, or the com- 
parable use of fruits, should be avoided as it presents more than a little 
danger to the patient (both violent illness and death have been reported). 
Hoehne (p. 206. 1920) says that Funifera is ‘““extremamente toxicas.” He 
further notes that cattle are adversely affected by grazing both Daphnopsis 
and Funifera and are stricken particularly from May to September (during 
the vegetative growth phase). 

An active principle has not been isolated but several compounds, mez- 
erein, daphnin, and umbelliferone, have been reported in several genera 
of the Thymelaeaceae. Hoehne (p. 206. 1920; p. 204. 1939) has reported 
both mezerein and daphnin present in Funifera. If these compounds, or 
chemically related ones, are more consistently present in the family than 
has been realized, they may provide the chemical basis for the similarity 
of application found in folk medicine throughout the world. The chemical 
composition of mezerein is unknown, most authorities referring it to the 
category of an “acrid resin.” Both umbelliferone and daphnin belong to 
a large group of related compounds having coumarin (for a most informa- 
tive paper on this compound see Brown, 1963) as a nucleus. Since the 
coumarin derivatives are found in many groups of plants their use as 
supplemental taxonomic characters is less important than might have been 
expected. Umbelliferone is known to absorb ultraviolet light and has been 
used as sunburn protection, and as a whitening agent in soap powders. 
Specific uses for daphnin have not been reported. Coumarin has been used 
commercially as an adulterant or substitute for vanilla, as an adulterant of 
tobacco, and in the perfume trade. It has a fragrant odor and burning 
taste. A coumarin derivative could account, in part, for the peculiar and 
distinctive odor of many thymelaeaceous plants. In general, coumarin 
is considered nontoxic to mammals although Pammel (p. 552) points out 
that “Dr. Millspaugh states that in large does, [it] causes nausea, vomit- 
ing, vertigo, great depression of the heart’s action and cold extremities.” 
Dean (p. 241) further states that . . . “larger animals (e.g., dogs, horses) 
can be killed by coumarin, but moderate quantities have no very marked 
effect on man except that it has been reported recently that coumarin 
has a true curare-like activity.” It is impossible to say whether a single 
compound or a group of compounds is responsible for the similarity of 
medicinal uses to which thymelaeaceous plants are put but the latter al- 
ternative seems more likely. It is clear that more precise diagnostic 
and physiological data are needed for all the compounds mention

Several manuscript names appearing on specimens of this species have 
been published as synonyms. The two pistillate sheets of Martius s.n. 
deposited at Munich bear the name “Neesia daphnoides” and are the 
basis for that name. The microfiche of this collection from the DeCandolle 
herbarium (c-pc) shows one specimen, Lhotsky “1832,” bearing the name 
“Daphne Thereminii.’”” Both of these names were published by Meissner 
as synonyms in Martius’ Flora Brasiliensis. Another sheet in the DeCan- 
dolle herbarium, Martius “1823,” bears an unpublished name. 

Several problems have arisen in connection with the geographic dis- 
tribution of Funifera brasiliensis. It seems to me that the plants are 
restricted to the Carioca, Tijuca, and Gavéa ranges with a disjunct popu- 
lation, to the north, at Cabo Frio. The single collection from the last 
named locality is fragmentary but appears to be this species. Positive 
determination must await collection of flowering material. Several cryptic 
reports indicate that the species occurs as far south as Sao Paulo but I 
have seen no material to support the claim. In addition, José Correa 
Gomes, Jr., Curador do Herbario, has written that no material of the 
genus is on deposit at the Instituto de Botanica, Sao Paulo. 

I have listed Allemdo Cysneiros 1347 as being from a questionable 
locality. The specimen bears three labels: one, a handwritten label with 
“Lagetta funifera (Mart.)” and the family name; a second label with the 
collector’s name and title (M. N. PLANTAS DA COMM. SCIENT. DO 
CEARA.) printed, the collector’s number (1347) and identification hand- 
written; the third label is recently printed and typewritten. Cysneiros 
collected in the state of Ceara from 1859 to 1861. It is not at all clear 
whether the label is associated with the proper plant, for this locality is 
not in accord with the range of Funifera brasiliensis as understood at this 
time. A second sheet, with the initials A. C., which I assume to have been 
collected by the same man, in 1875, is from “Rio.” | a 

A specimen at Leiden, collected by Vincent in 1915, marked “Para” is 
questionable. Surely “Para” refers to a local name and not to the state 


238 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


of Para, but I have not found such a locality within the known range of 
the species 

The collections of Ludwig Riedel have been cited by number and year 
of collection to avoid confusion. His two earliest Brasilian collections were 
not numbered; his subsequent collections (four excursions) were each 
independently numbered. A note explaining this system plus a biographic 
discussion can be found in Urban’s “‘Biographische Skizzen. II. 2. Georg 
Heinrich v. Langsdorff (1774-1852) und 3. Ludwig Riedel (1790-1861)” 
Beibl. Bot. Jahrbiich. 44: 6-21. 1894 (see especially p. 20) 

In this species, Funifera brasiliensis, growth seems to occur in flushes, 
with stem elongation and flower production taking place simultaneously. 
Following anthesis, one or more axillary buds subtending the inflorescence 
develop and form the peculiar branched structure characteristic of the 
shrubs of this species. Shortly after the lateral vegetative shoots elongate, 
the leaves mature and the plants enter a resting phase 

Notes on several herbarium specimens indicate the possibility of de- 
velopment of an enlarged underground stem in older specimens. It is 
believed that these underground stems would be advantageous for survival 
in areas subject to frequent burning. This adaptation occurs in several 
African genera but is suspected only in a few cases involving American 
Thymelaeaceae.

It is unfortunate that both of the specimens, which I believe represent 
an undescribed species, are incomplete. The plants resemble Fumnifera 
brasiliensis most closely but differ from it in important vegetative and 
floral characteristics. There is no question that better and more complete 
material will be collected in the future so I do not feel that it is wise to 
describevthe species formally at this time.

GRISEBACH’S FLORA OF THE BRITISH WEST INDIAN ISLANDS: 
A BIOGRAPHICAL AND BIBLIOGRAPHICAL INTRODUCTION 


WILLIAM T. STEARN 


DESPITE THE PASSAGE OF TIME the Flora of the British West Indian 
Islands (London. 1859-1864) by August Heinrich Rudolf Grisebach 
(1814-1879) is a work which students of the Caribbean flora must neces- 
sarily often consult on account of the many new specific names and 
nomenclatural combinations published therein, as well as for taxonomic 
information. Indeed, little taxonomic work on West Indian plants can be 
done without reference to it. The following notes on this Flora were 
originally compiled about 1960 to form an introduction to a facsimile 
(Historiae Naturalis Classica, no. 30), which through a misunderstanding 
was published in 1963 without them. They deal with its dates of publica- 
tion (p. 263), the area covered (pp. 260-263), the abbreviations for 
literature employed by Grisebach (pp. 276-285), and the collectors (pp. 
264-272) whose material he cited. To these have been added a short 
biography of Grisebach (pp. 245-249) and a chronological list of his 
publications (pp. 249-260). 

Historically Grisebach’s Flora is of interest as the first of a series of 
British colonial floras initiated at Kew by Sir William Jackson Hooker ~ 
(1785-1865). As stated in a memorandum of 1863 on colonial floras, 
“the publication by Government of a series of inexpensive portable 8vo 
works, illustrative of the vegetable products of the British possessions, has 
long been contemplated by the Director of the Royal Gardens of Kew. 
To him, in his official capacity, incessant applications for information on 
the vegetable products of our Colonies are made, by the Home and Colo- 
nial Governments and by private individuals, especially merchants and 
manufacturers; and he is habitually applied to by travellers and emi- 
grants for the names of such books as will enable them to obtain precise 
information about the plants of the different Colonies.” Grisebach’s Flora 
was, however, “commenced before the general plan was entertained; and 
neither the plan, size, nor typography of the work, nor the sequence of the 
orders are uniform with the Floras since undertaken.” Bentham’s Flora 
Hongkongensis (1861) served as a model for these. It is of interest to 
note that the British West Indies were then estimated to possess 2,000

years before, during his professorship at Glasgow (1820-41), he had been 
receiving specimens and plants from his correspondents in the West Indies, 
notably Scots, and his eldest son had emigrated to Jamaica (where he died 
in 1840). One of Hooker’s first acts on becoming director of the formerly 
private royal gardens at Kew was to send Purdie to Jamaica to get West 
Indian plants for the expanding Royal Botanic Gardens now open to the 
public. The period during which these collections were made coincided 
with one of economic decline in the British West Indies. As stated by 
Parry and Sherlock, “one disaster followed another: bankruptcy and finan- 
cial chaos in the eighteen-forties, droughts and epidemics in the eighteen- 
fifties, rioting and bloodshed in the eighteen-sixties” (Short Hist. West 
Indies, 188. 1956). The will and means for founding institutions of 
higher learning existed neither among the planters nor the emancipated 
slaves. Encouragement for the scientific study of the plants of the British 
West Indies and for further collecting had therefore to come from outside 
the area. With the completion of Grisebach’s Flora this external stimulus 
ended and local interest languished. Instead of forming the basis for yet 
more investigation, the Flora gave the impression by its apparent exhaus- 
tiveness that no further investigation was needed. Particularly did this 
apply to Jamaica, where between 1860 and 1880 almost all botanical 
activity ceased. 

Renewed collecting in Jamaica, following the appointment in December, 
1879, of Daniel Morris (1844-1933) as director of Public Gardens and 
Plantations and his founding of a Botanic Department herbarium for 
Jamaica, quickly demonstrated the unreality of such a view.’ By 1909, 
according to Urban (Symb. Ant. 6: 84. 1909), the new botanical explora- 
tion had led to an increase of 358 species of flowering plants above those 
recorded for Jamaica in Grisebach’s Flora, 285 of them being species new 
to science. Most of these discoveries stood to the credit of William Harris 
(1860-1920) who went out to Jamaica as a gardener in 1881; most of the 
support for his work came from the interest and encouragement of Ignaz 
Urban (1848-1931) in Berlin and Nathaniel Lord Britton (1859-1934) in 
New York. 


BIOGRAPHY OF GRISEBACH 


August Heinrich Rudolf Grisebach was born on 14 April 1814, at 
Hanover, north Germany, where his father Rudolf Dietrich Grisebach 
(d. 1837) was auditor general of the kingdom of Hanover. His mother’s 
brother, the Géttingen professor Georg Friedrich Wilhelm Meyer (1782- 
1856), author of Primitiae Florae Essequeboensis (1818), Chloris Hano- 
verana (1836), and other botanical works, encouraged and directed his 
early interest in natural history. After schooling at Hanover and Ifeld 
he entered, in the autumn of 1832, the university of Gottingen, studied 
botany here under H. A. Schrader and F. G. Bartling, as well as medicine,

for five terms, then moved to the university of Berlin in April 1834, to 
complete his studies, becoming doctor medicinae et chirurgiae in April 
1836. At Berlin he came under the influence of C. S. Kunth, H. F. Link, 
F. J. F. Meyen, and M. J. Schleiden; as his doctoral dissertation he pre- 
sented Observationes quaedam de Gentianearum Familiae Characteribus 
(Berlin. 1836), a pamphlet of 37 pages preliminary to his massive Genera 
et Species Gentianearum adjectis Observationibus quibusdam phytogeo- 
graphicis (364 pages, Stuttgart & Tiibingen. 1838). Already in 1833 he 
had botanized in southern France and had become interested in the asso- 
ciations of plants characteristic of regions and habitats. Alexander von 
Humboldt’s travels inspired him as they did Charles Darwin. From Berlin 
he moved back to Gottingen in 1837. 

In March 1839 Grisebach set out on the most important journey of his 
life, a botanical expedition to the Balkan Peninsula (he extended the use 
of the term Rumelia to cover all the central region then under Turkish 
rule) and north-west Asia Minor (Bithynia), which had long captivated 
his imagination, this region being virtually unexplored from the botanical 
standpoint and little known in other aspects. He left Vienna on 2 April 
1839, and travelled by water to Istanbul (Constantinople), first down the 
Danube to Tulcea (Tuldscha) and Sulina, then south along the Black Sea 
coast of the Balkan Peninsula to Istanbul where he arrived on 17 April. 
As interpreter, servant, and cook he engaged a reliable Greek who spoke 
fluently Turkish, Greek, Arabic, French, and Italian and travelled with 
him, by way of Uskiidar (Scutari), Kartal, Yalova, and Gemlik (Kemlik) 
to Bursa (Brussa) which they reached on 2 May. Four days later Grise- 
bach climbed to the snowline of the Ulu Da& (Olympus Bithyniae). He 
distinguished on this mountain three main zones of vegetation: the region 
of sweet chestnut (Castanea), ca. 50-2500 feet, the region of conifers, 
2500-4600 feet, the alpine region, 4600-6920 feet. He then returned to 
Istanbul, visiting Mudanya (Modania) on the way. Back in Istanbul he 
met Fortunato Pestalozza, an Italian doctor from Milan, who later sent 
him and also Boissier many specimens from Asia Minor. Grisebach left 
Istanbul on 18 May, then travelled westward, by way of Tekirdag, to Enez 
(Enos) in Thrace, reaching this on 25 May and leaving it on 30 May. He 
then went on to Maronia (Marogna), taking ship from here to the island 
of Thasos (Tassos) and thence to Athos (Hajion-Oros), where he stayed 
from 3 June to 12 June surveying its vegetation. He then crossed Khal- 
kidhiki, by way of Kholomonda (Cholomonda) to Thessaloniki (Salonichi). 
This he reached on 16 June and left on 24 June, from here travelling 
northwestward to Edhessa (Vodena) in Macedonia, thence to Bitola 
(Monastir, Bitolia), Prilep (Perlepe), Skopje (Ueskueb), Tetovo (Tet- 
tova) and Kalkandele at the foot of the Sar Planina (Scardus). On 14 
July he made an ascent of Scardus reaching the peak (2496 meters high) 
of Ljuboten (Ljubatrin) on 17 July and Kobelica (Kobelitza, 2526 meters 
high) on 22 July. This survey provided both many observations on the 
altitudinal zoning of vegetation and many specimens of hitherto unknown 
species. His route now took him from Prizren (Prisdrén) westward over 


1965] STEARN, GRISEBACH’S FLORA 247 


north Albania to Shkoder (Scutari), which he reached on 27 July, leaving 
on 31 July for Lastua at the southern tip of Dalmatia. Here his Rumelian 
journey ended. In three months he thus covered a transect of the Balkan 
Peninsula between 40° and 42° N. and from sea-level to 2526 m. 

The scientific results of this journey across Thrace, Macedonia, and 
Albania, made when Grisebach was 25 years old, entitle it to rank in 
botanical history with the celebrated journey into floristically unknown 
Lapland made a little over a hundred years earlier by Linnaeus at the age 
of 25. His Reise durch Rumelien und nach Brussa im Jahre 1839 (2 vols., 
Gottingen. 1843-46) gives a general account of his travels. His Spicile- 
gium Florae Rumelicae et Bithynicae (2 vols., Brunswick. 1843-45) is 
a systematic enumeration of the plants then collected, its value as a 
pioneer flora of the Balkan Peninsula being increased by the inclusion of 
plants collected here and in Bithynia by Friedrichsthal, Frivaldzki and 
Pestalozza, and by references to those described by Buxbaum, Sibthorp 
and Smith, and others. This journey laid that foundation of first-hand 
knowledge of types of European vegetation on which Grisebach built his 
later phytogeographical work culminating in his Vegetation der Erde 
(1872). In 1842 he made a journey to Norway in order to become 
acquainted with northern vegetation; this provided the material for his 
paper “Uber den Vegetationscharacter von Hardanger” in Wiegmann’s 
Archiv fiir Naturgeschichte 10: 1-28. 1844 

Late in 1847 Grisebach became full professor (professor ordinarius) of 
botany in the medical faculty of the University of Gottingen, having been 
a privatdocent there from 1837 to 1841, associate professor (professor 
extraordinarius) since 1841, and here he remained during the rest of his 
life, for his loyalty to Géttingen, which during its hundred years of exist- 
ence had become a leading academic center of Germany, led him to 
decline the offer of professorships elsewhere, i.e. at Giessen in 1846, at 
Leipzig in 1851 and again in 1866, at Berlin in 1851, at Munich in 1855, 
and at St. Pétersbourg in 1855. 

Although Grisebach’s monographic work on Gentianaceae had extended 
his studies far beyond the European flora, his travels and his collections 
naturally concentrated his attention mostly on European plants. For a 
long time, however, he had wished to investigate the vegetation of a 
tropical area with the aid of extensive material. The tragic death of W. G. 
Walpers in 1853 led him to Caribbean botany. Walpers possessed a large 
collection of herbarium specimens, enriched with notes and drawings, 
which had been made in Guadeloupe, Panama, and St. Thomas by the 
Guadeloupe-born French doctor and naturalist, Placide de Fontbressin 
Duchassaing (1818-1873). He gave this valuable material to W alpers 
for publication, but Walpers, who had evidently become mentally dis- 
ordered, did nothing worthwhile with it and after his suicide Grisebach 
purchased it all. In the course of determining Duchassaing s plants Grise- 
bach catalogued not only these but also all the other species recorded? im 
the literature from the West Indian islands between 15° and 19 N., i.e. 
between Martinique and St. Thomas. He published this list in 1857 as 


248 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


“Systematische Untersuchungen iiber die Vegetation der Karaiben insbe- 
sondere der Insel Guadeloupe” (Abhandl. Kon. Ges. Wiss. Gottingen 
(Phys.) 7: 151-286). “About the same period,” as Grisebach states in 
the preface to his Flora of the British West Indian Islands, “Sir W. Hooker 
was exerting himself to procure the publication of a complete series of 
Colonial Floras . . . and consequently entrusted the elaboration of the 
present volume to myself, putting all the materials of the Hookerian 
Herbarium and the Kew Museums at my disposal, and procuring a grant 
of £300 to meet the necessary expenses. . . . Four times I went over to 
England, to compare my own West Indian herbarium with that at Kew; 
whilst all those forms which proved not to be in my possession were most 
liberally placed in my hands to be examined at Gottingen. . . . For a 
series of doubtful West Indian plants mentioned by older authors I have, 
when sojourning in London, consulted the Banksian collection of the 
British Museum, but not to as great an extent as might have been desirable. 
All those Swartzian species, however, which I had no opportunity of seeing 
there, were kindly sent for inspection by Professor Andersson, of Stock- 
holm, and these proved most important . . . the only authentic informa- 
tion as to certain Swartzian species is to be derived from his originals, 
either in the possession of the Academy of Stockholm, or of the British 
Museum. 

This Flora of the British West Indian Islands was “intended to be a 
synopsis of all vascular plants as yet known to inhabit the British West 
Indian possessions.” The descriptions were accordingly made as concise as 
possible, synonymy was kept to a minimum and, in general, only illustra- 
tions were cited. Keys were omitted and distribution only briefly indi- 
cated. Grisebach toiled at it intensively, continuously, and rapidly, and 
its completion was a remarkable achievement. He was a very able botanist, 
but the work swarms with mistakes, some due to the insufficiency of 
material but most of them attributable to the high speed with which it was 
prepared; Urban has noted that his errors are especially numerous among 
species with very small flowers, which require time-consuming observation. 
While engaged on this task Grisebach received a set of specimens collected 
in eastern Cuba by Charles Wright (1811-1885). This material and 
observations made while working on the Flora led him to publish two 
important papers in 1860, namely, “Erlauterungen ausgewahlter Pflanzen 
des tropischen Amerikas” (Abhandl. Kin. Ges. Wiss. Gottingen (Phys.) 
9: 3-58) and “Plantae Wrightianae, e Cuba Orientali.” Pars 1 (Mem. 
Am, Acad. Arts & Sci. N.S. 8: 503-536). He never visited the West 
Indies himself, and the greater part of them had yet to be explored 
botanically. In 1865 he published a paper on “Die geographische Ver- 
breitung der Pflanzen Westindiens” (Abhandl. Kén. Ges. Wiss. Gottingen 
(Phys.) 12: 3-80) summarizing phytogeographical information as then 
available. According to this, the known flora consisted of about 4400 
species of flowering plants and 400 of vascular cryptogams, the endemic 
species being apportioned as follows:

RENADA 2 . Turks Ist.) 18 


These figures are low because some of the areas rich in endemic plants 
had then scarcely been entered by botanical collectors. The known West 
Indian flora consists of about 10,000 species of phanerogams and 600 of 
vascular cryptogams. 

Work on Philippi’s and Lechler’s collections from southern Chile and 
the Straits of Magellan (see Abhandl. Kén. Ges. Wiss. Géttingen (Phys.) 
6: 89-138. 1856) and on the Malpighiaceae of Central America and 
Brazil gave him an acquaintance with the flora of the American mainland. 
This was extended further by the receipt for naming of big collections of 
Argentinian plants made by Paul Giinther Lorentz eae 1881) ? and by 
Georg Hieronymus (1846-1921) ® which he catalogued in “Plantae Lorent- 
zianae” (Abhandl. Kon. Ges. Wiss. Gottingen (Phys.) 19: 49-278. 1874) 
and ‘‘Symbolae ad Floram Argentinam” (Abhandl. Kén. Ges. Wiss. Got- 
tingen (Phys.) 24: 3-346. 1879). 

Meanwhile Grisebach had become the world’s leading authority on 
plant geography, partly through his own field-work, partly by the study of 
herbarium collections from many lands, partly through the analysis of 
innumerable floristic and geographical publications. Already in 1838 he 
had published a paper in Linnaea (12: 159~200. 1838) “Uber den Ein- 
fluss des Climas auf die Begranzung des natiirlichen Floren,” and from 
1841 to 1856 he published yearly reports on plant geography and systematic 
botany. He brought together the fruits of this study in his monumental 
Die Vegetation der Erde nach ihrer klimatischen Anordnung (2 vols 
Leipzig. 1872), translated into French as La Végétation du Globe @ apres 
sa Disposition suivant les Climats (2 vols. Paris. 1875-78). This and the 
Flora of the British West Indian Islands are his most important single 
contributions to botanical literature. In 1878, at the age of 64, he began 
an even more ambitious undertaking, a Flora Europaea, of which he wrote 
the text relating to Ranunculaceae, Berberidaceae, Papaveraceae and part 
of Cruciferae during the winter of 1878-79, but which his death on 9 May 
1879, from Bright’s Disease, prevented him from publishing even in part. 
The fragment was, however, published by Agost Kanitz, in 1882, under

Im Jahre 1850 unternahm Grisebach eine grossere wissenschaftliche Reise in 
die Pyrenien, auf welcher u. a. die Hieracien besonders studirt wurden, deren 
Monographie er vorbereitete. Es erschien in diesem Jahre:

wachse. Berlin 1850. (Recens. in: Géttinger Gel. Anzeigen vom 27. Marz 

1850 p. 481-93) 


1851 machte er mit A. Schenk eine gemeinsame Forschungsreise in die Alpen, 
namlich durch das westliche Tirol, das Engadin, die Lombardei, Piemont und 
Dauphiné, als deren Frucht veroffentlicht wurde: 

74. Observationes quaedam de plantis, quas in itinere alpino a. 1851 suscepto

Den Herbst des Jahres 1852 benutzte er zu einer botanischen Reise, wieder 
mit Schenk, in die Karpaten. Die Ergebnisse sind niedergelegt in

Spater (1867 s. unten Nr. 113) bemerkte Grisebach iiber diese Schrift: 
“Meine in den Schriften der Géttinger Societat iiber die Hieracien veroffentlichte

aus ausseren Einfliissen ableiten zu kénnen, nicht in Erfiillung ging.”

SCOPE OF GRISEBACH’S FLORA 


Although long out of date in much of its nomenclature and taxonomy, 
often unreliable in matters of detail and concerned only with the British 
West Indian Islands, which occupied only about an eighth of the total land 
area of the West Indies and by 1864 had been far from exhaustively 
explored botanically, Grisebach’s Flora remains nevertheless the most 
comprehensive general descriptive guide to the plants of the archipelago 
stretching from the Bahamas and the Florida Keys to Trinidad and 
Aruba. 

Floristically these islands may be divided into five main groups, those 
covered by Grisebach’s book being cited in LARGE and SMALL CAPITALS: 

1. The Bahamas, i.e. the BAHAMA IsLANDS comprising 29 major 
islands and about 3,000 islets (in all 4,403 sq. miles) + and the Turks 
and Caicos Islands (170 sq. miles.) 

. The Greater Antilles, consisting of Cuba (44,178 sq. miles), 
Hispaniola (29,838 sq. miles), Jamatca (4,411 sq. miles), Cayman Islands 
(100 sq. miles), Puerto Rico (3,450 sq. miles) and the Virgin Islands 
(67 sq. miles), and separated by the deep Anegada Passage from the 
Lesser Antilles proper. 


*1 square mile = 2.59 square kilometers. 








Fic. 2. THE West INpIAN ISLANDS. Roman numerals refer to “the five natural sections” noted by Grisebach 
(for discussion of this division see page vi of Grisebach’s text). The islands considered by Grisebach are in 
solid black.

262 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


3. The Lesser Antilles: 

(a) Leeward Islands, between the Anegada Passage and the Martin- 
ique Passage, including Anguilla (35 sq. miles), St. Martin (38 sq. miles), 
St. Barthélemy (8 sq. miles), Saba (5 sq. miles), St. Eustatius (9 sq. 
miles), St. Kirts (68 sq. miles), Nevis (50 sq. miles), BarBupaA (62 
sq. miles), ANTIGUA (108 sq. miles), MONTSERRAT (32 sq. miles), Guade- 
loupe (Grande Terre, 255 sq. miles; Basse Terre, 364 sq. miles), Marie 
Galante (60 sq. miles), Dominica (305 sq. miles); the Virgin Islands 
are usually listed under the Leeward Islands. 

(b) Windward Islands, from the Martinique Passage south to 
Grenada, including Martinique (430 sq. miles), St. Lucta (238 sq. miles), 
St. VINCENT (150 sq. miles), Bequia (7 sq. miles) The Grenadines (13 
sq. miles), GRENADA (133 sq. miles). 

BARBADOS (166 sq. miles). 
Alternatively 

(a) Eastern Arc: Anguilla, St. Martin, St. Barthélemy, BARBupA, 
Antisua, Guadeloupe (Grande Terre), Désirade, Marie Galante; these 
form a series of old limestone-topped volcanic islands 

(b) Western Arc: Saba, St. Eustatius, St. Kitts, Nevis, MONTSER- 
RAT, Guadeloupe (Basse Terre), Dominica, Martinique, St. Lucia, ST. 
VincENT, Bequia, The Grenadines, GreNnapA; these form a series of 
younger volcanic islands. 

c ARBADOS. 

4. Tobago (116 sq. miles) and Trinidad (1,864 sq. miles). 

5. Southern Caribees, consisting of Aruba (67 sq. miles), Curacao 
(164 sq. miles), Bonaire (93 sq. miles), etc. 

Trinidad belongs geologically and floristically not to the West Indies 
but to northern South America, as Grisebach pointed out as long ago as 
1865: “schon jetzt ist man indessen berechtigt, Trinidad von Westindien 
nach seiner Pflanzenproduktion zu trennen und als ein Glied des Festlandes 
zu betrachten.”” The Lesser Antilles are similarly independent of the 
Greater Antilles. An observation by Alston (1952) emphasizes this: “the 
80 miles of sea separating Tobago from Grenada, and the 120 miles which 
separate St. Thomas from Saba are more formidable barriers to Selaginella 
than the 90 miles between Cuba and Jamaica, and there seems to be no 
reason for this but the geological history of the various islands” (Bull. 
Brit. Mus. (Nat. Hist.), Bot. 1: 28). Barbados and Tobago are on the 
same South American continental shelf and thus not geologically as- 
sociated with the volcanic Lesser Antilles. As a result of covering such 
a heterogeneous assembly of islands Grisebach’s Flora includes most of 
the widespread tropical lowland weeds, together with many endemic 
West Indies species and a number of characteristic South American 
species. 

According to an analysis by Krug in Urban, Symb. Ant. 1: 57. 1898, 
Grisebach recorded from the individual islands the following number of 


1965 | STEARN, GRISEBACH’S FLORA 263 


species of vascular plants (to which some more recent estimates or counts 
are added in parentheses for comparison) : 
BAHAMAS 191 (995 phanerogams, 69 pteridophytes, fide Britton & Millspaugh, 
1920). 


JaMaAica 2303 (approx. 2900 phanerogams, 540 pteridophytes). 
St. Kitts 129 (no total for phanerogams available; 129 pteridophytes). 
NEvis 11 (no total for phanerogams available; 83 pteridophytes ) 


MontTseErRRAT 48 (no total for phanerogams available, 68 pteridophy tes). 
Domrnica 684 (no total for phanerogams available, 191 pteridophytes 
Sr. Lucta 82 (no total for phanerogams available, approx. 120 pteridophytes). 


Tosaco 4 (no total for phanerogams available, 95 pteridophyt 
TRINIDAD 1,282 (approx. 2,200 phanerogams, 300 peatetes:. 


This gives a total of 3,143 phanerogams, 356 pteridophytes. Grise- 
bach’s Flora thus deals with about a third of the phanerogam species 
and about half of the pteridophyte species known from the West Indian 
archipelago between Florida and Venezuela.

BIOGRAPHICAL NOTES ON COLLECTORS 


Grisebach based his Flora chiefly on herbarium material assembled 
at the Royal Botanic Gardens, Kew, through the enterprise of William 
Jackson Hooker. This material included many specimens collected by 
residents, mostly medical men, in the British West Indies, notably Ban- 
croft, Crueger, Distin, Finlay, Guilding, Imray, Lane, Lockhart, Mac- 
fadyen, Gilbert McNab, March, Nicholson, Schack, Robert Schomburgk, 
Waters, Wiles, and Wilson. For Jamaica the most interesting and ex- 
tensive collections studied were those made by Purdie, sent out from 
Kew in 1843, and by Alexander (later Prior), who visited Jamaica in 
1849-50. Grisebach came to England four times during the preparation 
of the work and was able to have much material from Kew on loan a 
Gottingen and to retain fragments for his private herbarium, which re- 
mains at Gottingen. He also had available the collections, not repre- 
sented in British herbaria, made by Wullschlagel and Bertero. The his- 
toric collections by Sloane, Masson, Roger Shakespear, Swartz, and 
others, then at the British Museum, Bloomsbury, now at the British 
Museum (Natural History), South Kensington, London, were known to 
Grisebach but he made little use of them, probably because they were 
then less accessible than the later collections at Kew. 

The following notes on collectors cited by Grisebach are based on 
Urban’s “Notae biographicae peregrinatorum Indiae occidentalis botani- 
corum” in Symbolae Antillanae 3: 14-158. 1902, but provide some in- 
formation not available to Urban.

Spain, Trinidad, and the Parish of St. Ann, Jamaica; ‘several species 
credited to St. Anne’s, Jamaica, have not been re-found and it may be 
well to note that locality as doubtful. From many circumstances I feel 
diffident about attaching any importance to Purdie’s specimens from St. 
Anne’s, Jamaica, most of the specimens so credited being found in St. 
Anne’s, Trinidad, the district in which the Botanic Gardens are situated.”

COLLECTORS GROUPED BY ISLANDS 


The following conspectus lists chronologically under each island the 
botanical travellers and residents in the British West Indies who, by 
collections or records, contributed to a knowledge of their flora down 
to the year 1900. It has been extracted with slight modification from 
Urban’s more extensive “‘Conspectus insularum earumque peregrinatorum 
botanicorum” in Symbolae Antillanae 3: 147-158. 1902. Persons listed 
within brackets, e.g. [J. B. Labat between 1694-1705], are not known to 
have left herbarium specimens although they made notes, sometimes inci- 
dental, on plants. Collectors cited by Grisebach are italicized, e.g. O. 
Swartz.

LITERATURE CITED BY GRISEBACH ° 


Grisebach’s references to literature in the Flora are restricted for the 
most part to concise citations of plates and figures. Although many of 
these are self-evident, a number require much amplification in order that 
the works concerned can be traced in a library catalogue. After each 
entry below are given references to G. Pritzel’s Thesaurus Literaturae 
botanicae, 2nd ed. (1872) cited as “Pr.” with an entry number, to Urban’s 
“Bibliographia Indiae occidentalis botanica” in I. Urban, Symbolae Antil- 
lanae 1: 1-179. 1898, cited as “Urb. 1” with a page number, to C. Nissen’s 
Die botanische Buchillustration 2. 1951, cited as “Niss.”’ with an entry 
number, and to C. Stevenson’s Catalogue of botanical Books in the Col- 
lection of Rachel M. M. Hunt 2. (11). 1961, cited as “Hunt” with an 
entry number.

THE GENERA OF TILIACEAE AND ELAEOCARPACEAE

TILIACEAE A. L. de Jussieu, Gen. Pl. 289. 1789, nom. cons. 
(LINDEN FaMILy) 


Trees to perennial or annual herbs woody at base, usually pubescent 
with simple and/or stellate hairs; inner bark fibrous; mucilage cells and 
cavities or, more rarely, ducts, in inner bark and often in pith, leaves, and 
flowers. Leaves alternate, simple, usually palmately veined at base, some- 
times palmately 3[—7]-lobed, toothed, petioled, stipulate, the stipules 
usually small, caducous to persistent. Inflorescences bracteate, simple, 
solitary or fascicled cymes, sometimes reduced to solitary flowers, opposite 
the leaves or + leafy bracts, or axillary and/or terminal, sometimes 
forming cymose panicles or chyrses, Flowers pediceled, small |to large], 
regular, hypogynous, 5[4|-merous, usually bisexual. Sepals [4] 5, distinct 
[or connate|, sometimes nectariferous at base within, valvate in aestiva- 
tion. Petals [4] 5, distinct, usually yellow or yellowish sometimes 
nectariferous at base within, imbricate or convolute in aestivation [or 
wanting|. Nectariferous disc, when present, aati encircling the 
stamens, cup-, ring-, or disclike, somewhat fleshy to membranaceous, on 
the flat receptacle or at apex of an androgynophore. Androgynophore 
present or absent. Stamens numerous (rarely few), usually distinct [re- 
duced and sterile in ¢ flowers], the 5 innermost [or 5 to many outermost | 
sometimes staminodia; filaments elongated, filiform, sometimes bifurcate 
at apex; anthers introrse or extrorse, the anther halves contiguous or 
separated at the tips of the bifurcate filament, dehiscent by longitudinal 
[or apical] slits; pollen medium sized [rarely large], usually 3-colporate, 
oblate to prolate, subreticulate or reticulate, the pattern often very compli- 
cated. Gynoecium usually 2—5-carpellate, syncarpous [rudimentary in ¢

flowers]; stigma large or small, usually lobed; style single; ovary superior, 
usually 2—5-locular, sometimes appearing 3-10-locular through develop- 
ment of false partitions; ovules axile, in two rows, numerous to 2 [very 
rarely 1| in a locule, ascendent to pendulous, anatropous, apo- to epi- 
tropous, 2-integumented, with a thick nucellus. Fruit nutlike or a drupe 
[rarely a berry], capsule, or schizocarp, sometimes prickly [or winged]. 
Seed with [or without] endosperm, the embryo large, “spatulate” or 
“folded.” Type Genus: Tilia L. 


An almost exclusively pantropical family of about 45 genera and over 
400 species; only Tilia and the monotypic Entelea R. Br. (New Zealand) 
primarily of the Temperate zones; three genera (one naturalized) in our 
area. Four subfamilies and 16 tribes have been recognized in the family. 
The genera usually are well marked, especially on the basis of fruit 
characters. The three genera of our area have been placed in subfam, 
Tilioideae, but the delimitation of this group appears to be uncertain, at 
least from the standpoint of pollen morphology (cf. Tilia). 

Although data on floral biology are scarce, the usually showy flowers 
provided with various types of nectaries indicate that the family in general 
is adapted to insect-pollination. The flowers usually are bisexual, al- 
though part or all of the species of some genera are dioecious. Staminate 
flowers usually possess a rudimentary gynoecium, while carpellate flowers 
show antheriferous but sterile stamens. The androecium is basically two- 
seriate (diplo- or obdiplostemonous), but one series, often the antisepalous 
one, is sometimes completely suppressed. The usually numerous stamens 
supposedly have arisen by multiplication of an originally smaller number, 
in either one or both series. Indications of multiplication are seen in the 
splitting of staminal traces. Floral anatomical and embryological data 
are known for only a few genera of the family. The development of the 
embryo conforms to the Urtica variation of the Asterad-type. The placen- 
tation of the ovary usually is axile, apparently derived from the parietal 
condition which is still encountered in some species of a few genera (e.g., 
Trichospermum Blume subg. Coelomesum Burret). 

Chromosome counts recorded for 18 genera (41 species) are 2n = 14, 
16, 18, 28, 30, 32, 36, 40, 48, 82, and 164, suggesting that disploidy, 
polyploidy, and aneuploidy have been of importance in the evolution of 
Tiliaceae, 

The family is closely related to Scytopetalaceae, Sterculiaceae, Elaeo- 
Carpaceae, Bombacaceae, and Malvaceae, which together form a very 
natural order, Malvales (Columniferae), within which the family limits 
are often weak and uncertain. Derivation of this order from Dilleniaceae 
is thought possible. 

A few Tiliaceae yield commercial timbers. Some species of Corchorus, 
Triumfetta, Grewia L., Honckenya Willd., etc., yield fibers, either for 
commercial or local use. Species of Sparmannia L. f., Grewia, and Entelea 
are grown as ornamentals in warm parts of the country; Grewia biloba 
D. Don is hardy as far north as southern New England.

°““As sharply as the genus Tilia is distinguished from the related groups — 
by a number of peculiar aaa: just so difficult is the classification within the 
genus. The number of species can not indicated with certainty, because all species 
are connected with one another by transitions [transitional forms], geographic races, 
and numerous hybrids” (Jaccard & Frey, p. 3). (Translation supplied.)

tropical Asia, and one or two Mexico; absent from the Himalayas and 
Pacific North America. In eastern North America, Tilia occurs in rich 
woods from Nova Scotia, New Brunswick, and southern Quebec, south- 
ward to central Florida, and westward to central and western Texas, 
Oklahoma, and the eastern parts of Kansas, Nebraska, South and North 
Dakota, and southern Manitoba. In Mexico, the genus ranges from 
northern Coahuila, southward along the Sierra Madre Oriental to south- 
ern Mexico, with scattered stations in the Sierra Madre Occidental 
(McVaugh). There is great uncertainty regarding the number and 
delimitation of the species of Tilia within this broad range, because the 
characters used for distinguishing the species (e.g., presence or absence, 
amount, color, and type of pubescence on the lower surface of mature 
leaves; size, shape, and texture of leaves; and shape and size of leaf 
teeth) seem to be quite inconstant (apparently from frequent hybridiza- 
tion and introgression) and hardly of specific significance. The current 
tendency is to reduce the 15 species recognized in the United States by 
Sargent (1922) and the 14 distinguished in the southeastern United States 
by Bush (in Small, 1933) to four or even to one.’ For example, Braun 
(1961), who recognized in Ohio three “well-marked and fairly constant 


of the genus in America, are undertaken to determine probable hybridiza- 
tion and subsequent introgression resulting from Pleistocene migrations 
and commingling of older species, no satisfactory treatment is possible.” 

In wrestling with Tilia in northern Florida, Kurz and Godfrey (pp. 
230, 231) remark, “It is of more than passing interest that our material 
was subsequently borrowed by a student of Tilia and that individual 
herbarium specimens taken from separate parts of a single tree were des- 
ignated by him with more than one species name . . . Granting the fact 
that local populations of Tilia in our range do exiibit, in general, degrees 
of difference in their over-all pattern of characteristics, we are inclined to 
recognize but one variable complex, T. americana. It seems futile to 
attempt segregation into more taxa, certainly not without studies applying 
techniques and employing values other than those traditionally used. In 
northern Florida, T. americana, thus broadly interpreted, embraces a 
range of plants, some of which individually correspond to T. heterophylla, 
T. floridana [Small], 7. crenoserrata [Sarg.], and T. georgiana |Sarg.].” 
With specific limits so uncertain, it seems to be most reasonable at the 
present time to follow Kurz and. Godfrey in the recognition of a single 
variable species, T. americana L., sensu lato, 2n = 82, both in our area

and the entire United States. The taxonomy of the Mexican representa- 
tives needs to be considered in conjunction with this concept. 

The European Tilia cordata Mill., 2n = 82, and T. platyphyllos Scop., 
2n = 82, and the Eurasiatic T. petiolaris DC., 2n = 82, introduced into 
the United States, are reported to spread sometimes from cultivation to 
waste places and roadsides in the Northeastern States. 

The flowers are pollinated mainly by Hymenoptera, especially bees, 
and Diptera, the insects apparently being attracted, not only by the 
fragrance and often bright color of the flowers, but also by the large, 
yellow-green bract of the inflorescence. At least in European species 
wind-pollination also seems to be of importance (Eisenhut). Although 
proterandry and the relative positions of stigmata and anthers seem to 
prevent self-pollination in individual flowers, pollination from neighboring 
flowers of the same tree is said to occur side by side with cross-pollination. 
As Jordan (1886) showed, the nectaries are situated at the base of the 
adaxial surface of the sepals, not on the petals. 

The vascular ground plan shows that the androecium of Tilia is diplo- 
stemonous, consisting at an early stage of development of five antisepalous 
double groups of stamens of the outer whorl and five antipetalous stamens 
of the inner whorl. “As development proceeds the double group of 
stamens in front of each sepal separates into two half groups, with the 
result that in fully developed flower the whole androecium consists of five 
antipetalous phalanges |fascicles], each phalange |fascicle| being com- 
posed of a single antipetalous member in the centre flanked by half the 
antisepalous group on each side” (Saunders). Only the five originally 
antipetalous stamens usually are modified into staminodia. 

Chromosome counts (eleven species) are 27 = 82 and 164, suggesting 
that the genus is highly polyploid. Although many spontaneous hybrids 
are known from cultivation, and much hybridization between wild plants 
has been supposed, only a single wild putative hybrid, Tilia % vulgaris 
Hayne (T. cordata < T. platyphyllos appears to have been reported. 
This fully fertile hybrid is said to form pure stands in Lithuania and the 
Ukraine (Jaccard & Frey). 

The winglike bracts promote wind transportation of the infructes- 
cences; seeds are dispersed to a lesser degree by rain wash and by some 
frugivorous birds and mammals, especially rodents. Under natural con- 
ditions seeds germinate slowly and irregularly, sometimes remaining 
dormant for two to four years. Dormancy in Tilia americana is due to an 
impermeable seed coat and a partially dormant embryo. 

At least on the basis of wood anatomy, the genus has been regarded as 
closely allied to the Indochinese-Indonesian Schoutenia Korth. and 
Chartocalyx Maing. ex Mast., but these two genera have pollen of a 
more or less malvaceous type and seem to occupy an isolated and un- 
certain position in the family. The pollen of Tilia appears to be closer 
to pollen of the genera of subfam. Brownlowioideae (Benth. & Hook.) 
Burret than to that of the genera of subfam. Tilioideae (Erdtman, Pollen 
Morphol. Pl. Taxon., 1952).

Tilia americana, sensu lato, and the European T. cordata and T. platy- 
phAyllos supply highly valuable, soft, white lumber of great utility; the 
inner bark is sometimes used for making cordage. These and some other 
European and Asiatic species are cultivated as ornamentals, all being also 
esteemed as honey plants. Flowers of T. cordata, T. platyphyllos, and 
T. < vulgaris Hayne (often referred to as T. europaea L.) are officinal, 
at least in Europe. Seeds are said to be a source of oil for cooking and 
other purposes.

cotyledons foliaceous, entire; radicle superior. Lectotype sprctes: C. 
olitorius L.; see Britton & Millspaugh, Bahama FI. 262. 1920. (Name 
from Greek, korkhoros, an ancient name for some herbaceous pot plant, 
perhaps C. olitorius; etymology obscure.) 


A pantropical genus of about 40 species, centered in Africa (ca. 15 
species) and Australia (ca. 15 species), with several in Asia and America. 
Two tropical American and one pantropical species occur in our area. 
The American species, except the pantropical Corchorus aestuans L. and 
the East African-West Indian C. hirsutus L., seem to differ from those 
of the Old World at least in an obsolete disc in the flowers. 

Corchorus siliquosus L., 2n = 28, is a subshrub or perennial herb, with 
leaves only 1-3 cm. long and slender, nearly cylindrical capsules 5—8 cm. 
long, bearing four minute toothlike appendages at the nearly truncate 
apex. Occurring almost throughout tropical America, it extends north- 
ward through the West Indies to hammocks, cultivated ground, and road- 
sides of the Florida Keys and southernmost peninsular Florida, where it 
seems to be indigenous. Records from Texas need verification. Corchorus 
orinocensis HBK., usually a sparingly branched annual or perennial with 
slender, subcylindrical, slightly flattened capsules 4-7 cm. long and at- 
tenuated into a straight beak, is widely distributed throughout tropical 
America and similarly reaches southernmost Florida (Dade and Monroe 
counties). It is also known from Mobile and Tuscaloosa counties, Ala- 
bama, southeastern Louisiana, and from scattered localities westward 
through southern Texas to southern Arizona and Mexico. The Alabama 
occurrences (and perhaps those in Louisiana) seem to be incidental intro- 
ductions with subsequent naturalization (see R. M. Harper, Geol. Surv. 
Ala. Bull. 53: 152. 1944). A third species, the widely distributed C. 
aestuans L. (C. acutangulus Lam.), 2n = 14, is known as an adventive 
weed from at least Dade, Collier, Leon, and Escambia counties, Florida, 


1965] BRIZICKY, TILIACEAE & ELAEOCARPACEAE 297 


and Mobile County, Alabama. It is usually an annual, with bristle-like 
appendages on the lowermost pair of teeth of the leaves, a minute andro- 
gynophore bearing a disc at the apex, and stoutish, subcylindrical, 3 (—6)- 
angular and narrowly 3-winged capsules 1.5—-2 cm. long and terminated 
in three usually bifid horns. 

At least the cultivated Corchorus capsularis L., 2n = 14, and C. oli- 
torius L., 2n = 14, are short-day plants. The flowers of the two open 
respectively about an hour after and an hour before sunrise (Kundu). 
Cross-pollination by insects seems to be the rule, self-pollination ap- 
parently being prevented by the stigma’s overtopping the stamens. 

e inner, antisepalous whorl of stamens is completely suppressed, 
while the outer, antipetalous whorl is multiplied. The traces for the 
antipetalous stamens, which arise conjointly with those of the petals, divide 
primarily into three bundles: a median and two laterals. According to 
Rao, all three branch to form a large number of staminal bundles. The 
extrastaminal nectariferous disc (and sometimes an androgynophore) is 
present in the Old World species, but both seem to be absent (obsolete) 
in those indigenous to the New World. The stamens in a flower usually 
are distinct, appearing evenly distributed upon the receptacle, but some- 
times a few groups of two to four stamens with filaments connate for 
various lengths can be observed. The anthers are dorsifixed (not basifixed, 
as stated by some authors) and are usually vertical and nearly straight. 
The orientation of the ovules should be investigated, since both epitropy 
and apotropy have been recorded by various authors. 

Chromosome counts made for 12 species are 2m = 14 and 28 (three 
species). Although no conclusions can be drawn, it is notable that two 
of the tetraploids are American and one is Australian, while all the 
diploids are either Asiatic or African. A trisomic mutant showing ‘“dimor- 
phic gametes” (microspores?) with » = 7 and 8, and an aberrant trisomic 
branch (2n = 15) of a normal diploid plant have been recorded in 
Corchorus capsularis. Hypo- and hyperploidy have also been detected in 
all Indian species of the genus. Numerous attempts to produce artificial 
interspecific hybrids, especially between C. olitorius and C. capsularts, 
have been unsuccessful with both diploids and induced tetraploids. In 
1960, Islam and Rashid reported the first sucessful cross, C. olitorius 9 
x C. capsularis %, resulting in a few slow-growing, somewhat fertile 
hybrids. Chaudhuri and Jabbar Mia later published on successful crosses 
at the diploid level between C. olitorius and C. capsularis and the latter 
and C. trilocularis. These crosses resulted in vigorous and fertile hybrids, 
but C. capsularis ¢  C. trilocularis & , on the tetraploid level, resulted 
in sterile hybrids. All crosses of C. aestuans with these species were unsuc- 
cessful. 

The minute, very light seeds of Corchorus apparently can be distributed 
by wind (Islam & Khan), but the wide, even pantropical, distribution of 
some species seems to be due largely to casual introductions (e.g., in bal- 
last).

The genus occupies an isolated position in the Tiliaceae, representing 
a tribe of its own. A revision of the genus is very desirable 

The Indo-Burmese Corchorus capsularis and the presumably African C. 
olitorius are important economic plants, the main source of the commercial 
fiber jute. Grown extensively in India and East Pakistan, and to a minor 
extent in the Philippines, Formosa, Brazil, and elsewhere, both often be- 
come naturalized. Leaves or young shoots of these and some other wild 
species are eaten as eg and/or used in folk medicine in many 
tropical countries. Corchorus olitorius has been cultivated as a pot herb 
in the eastern ar acaba particularly in Egypt, from ancient times. 
Seeds of C. capsularis, C. olitorius, and some other species are poisonous, 
containing glycosides of the Digitalis type.

versity and director of the Botanical Garden in Rome.) 


A pantropical genus of over 100 species, apparently almost equally 
centered in tropical America and Africa, less abundant in Asia, Australia, 
and the Pacific Islands. At least four species, two aaturalized in the 
southernmost part of our area, are of pantropical distribution. Sprague 
and Hutchinson recognized four sections based primarily on fruit charac- 
ters. All American and most Old World species belong to sect. TRIUM- 
FETTA (§ Lappula DC. em. Sprague & Hutch.). 

riumfetta semitriloba Jacq., 2n = 32, occurs in cultivated ground, 
hammocks, and pinelands on the Florida Keys and in peninsular Florida, 
north at least to Manatee County, on the west coast, and Palm Beach 
County, on the east. It is a perennial herb or subshrub, with variable, 
generally ovate, unlobed to 3-lobed leaves; flowers with flat sepals, a well- 
developed disc, and 15-25 stamens; and nearly globular, subglabrous 
fruits with sparsely retrorsely hispidulous prickles. In contrast, T. pen- 
tandra A. Rich. is an annual or perennial herb with broadly ovate, unlobed 
to deeply 3-lobed leaves sparsely pubescent with simple and stellate hairs; 
flowers with cucullate sepals, a somewhat reduced to obsolete disc, and 5—8 
(13) stamens; and subglobular-ovoid fruits with + upright prickles 
plumosely pubescent on the adaxial side with straightish spreading hairs. 
It was collected in Sumter County, Florida, in 1900, but present status in 
our flora is uncertain.* Although apparently pantropical, the species seems 
to be most abundant in Africa and rather scattered and local elsewhere 
(Cape Verde Islands, Arabia, India, Ceylon, Formosa, Timor, and north- 
eastern Brazil). 

Cross-pollination by insects seems to be the rule, selfing apparently 
being prevented, at least in many species, by the position of the stigma 


(Man. p. 842. 1933) and Lay (p. 383) considered this species to be 
= 32 and 48 


1900”), is Sua the result of either einientilication or misinterpretation of the 
iu 2 


ochst is 
similar and closely related an T. rhomboidea, which differs mainly in the well-developed 
disc, (8) 10-15 stamens, and nearly globular fruits with a glabrous or sub- 
glabrous prickles. The Curtiss collection is clearly T. pentandra 


1965] BRIZICKY, TILIACEAE & ELAEOCARPACEAE 303 


above the stamens. Data on pollinators are scarce, but bees, little beetles, 
and flies are recorded for some Old World species. The flowers of Triuwm- 
fetta flavescens A. Rich. open at about 3 P.M. [Ethiopia] and those of T. 
macrophylla K. Schum. toward evening [East Africa]. “It is probable 
that the flowers of other species of Triumfetta open late in the day 
(Sprague and Hutchinson). 

The inner, antisepalous whorl of stamens in the flowers is completely 
suppressed. The trace for each of the outer, antipetalous stamens arises 
conjointly with a petal trace and then divides into three bundles, a median 


The laterals usually undergo a secondary branching in con- 
nection with the multiplication of the stamens, each lateral giving rise to 
traces to two or more stamens (Rao, 1952). Flowers with a low number of 
stamens have not been investigated. 

obturator, consisting of unicellular hairs, recorded by Rao & Rao 
for Triumfetta rhomboidea, is also present in T. semitriloba. 

Chromosome counts have been made for three species (27 = 32, 48). 
Occurrence of both 32 and 48 in Triumfetta rhomboidea suggests that the 
basic chromosome number of the genus is 8, rather than 16 as suggested 
by counts of 2n = 32 

Fruits in Triumfetta are either dehiscent and capsular to schizocarpous 
or indehiscent and nutlike at maturity, but often (perhaps always?) split- 
ting and freeing the seeds as the pericarp and partitions decay. Precise 
data on fruit dehiscence seem to be lacking; both loculicidal dehiscence 
and splitting into carpels or cocci are mentioned by various authors. The 
clinging fruit of ia of sect. TRIUMFETTA, with their hooked prickles, 
are dispersed by man and other animals. In the species with densely 
plumose-pubescent, here like fruit prickles (sect. LAsIorHRix Sprague 
& Hutch.), dissemination by wind may be assumed, while in some 
creeping, Indo-Pacific littoral species with fruits equipped with narrowly 
conical nonhooked prickles (sect. Porpa (Blume) Sprague & Hutch.), dis- 
persal by sea on floating pumice and on drifting logs has been recorded. 
The pantropical distribution of some species seems to be due mainly to 
human agency. 

The genus is closely related to Heliocarpus L., a tropical American 
genus centered in southern Mexico and Central America. A revision of the 
entire genus is desirable. 

Some species (e.g., Triumfetta rhomboidea, T. semitriloba, T. Lappula, 
T. cordifolia A. Rich.) yield fibers used locally in tropical countries for 
cordage, as well as for many domestic purposes; fibers from T. rhomboidea 
are said to be of commercial value. Leaves of several species are used as 
vegetables and also find some application in folk medicine. Trium- 
fetta rhomboidea is said by Wilczek to be a remedy for leprosy.

(ELAEOCARPUS FAMILY) 


Trees or shrubs, differing from Tiliaceae mainly in the absence of muci- 
lage cavities and ducts (although mucilage cells occasionally occur in the 
epidermis of leaves), in the considerably smaller spheroid to prolate 
pollen, and in the more primitive wood structure. Additional distinguish- 
ing characters include the occurrence of opposite leaves in some or a 
species of some genera, the prevalence of valvate petals and apical de- 
hiscence of the anthers, and the nearly regular occurrence of a nectarif- 
erous (extra- to intrastaminal) disc. TypE GeNus: Elaeocarpus L. 


A nearly pantropical family of about ten genera and 400 species, 
centered in Papuasia (five genera, ca. 190 species) and South America 
(five genera, ca. 70 species), with a few extensions into the South Temper- 
ate Zone; absent from continental Africa. The single species of Muntingia 
is becoming naturalized in southernmost Florida. 

Similarities in floral structure with Tiliaceae suggest a like floral biology 
and pollination by insects. Data from floral anatomy and embryology 
are few. Recorded chromosome counts (two genera, seven species) are 
2n = 24, 28, 30, suggesting aneuploidy. The petiolar anatomy appears 
to be more complex than in Tiliaceae. 

The family is closely related to and sometimes included in Tiliaceae, 
but evidence from anatomy and palynology seems to be in favor of re- 
taining the Elaeocarpaceae as a separate family. A relationship to 
Flacourtiaceae-Prockieae has also been postulated by some authors. 

Some species of a few genera yield tanbark or lumber of local im- 
portance. A few species of Aristotelia L’Hérit., Crinodendron Mol., and 
Elaeocarpus are grown as ornamentals in the southern part of our area 
and/or southern California.

faces, valvate. Petals 5(—7), distinct, white (rarely pink), thin, obovate, 
short clawed, equaling the sepals, imbricate and + crumpled in bud. Disc 
intrastaminal, annular, on the edge of the shallowly concave receptacle, 
bearing a ring of long, straight hairs on the exterior side near the margin. 
Stamens numerous, distinct, inserted at base and partly on the exterior 
surface of disc, half as long as the petals; filaments filiform; anthers 
elliptic in outline, shorter than the filaments, dorsifixed, versatile, introrse 
(latrorse), longitudinally dehiscent. Gynoecium 5-—7-carpellate, syncar- 
pous; stigma subsessile or sessile, subpyramidal, longitudinally 5—7-grooved 
and -ridged, with a sinuous stigmatic surface on each ridge; style very 
stout and short or wanting; ovary sessile or very short stalked, 5—7-locular, 
the locules becoming slitlike, pubescent, and confluent above the placentae; 
ovules very numerous, anatropous, epitropous, on 2 + ovoid placentae 
pendulous from the axis at the top of each locule. Fruit a subglobular 
berry, ca. 1 cm. in diameter, red or yellow, appearing irregularly many- 
locular, sweet, edible. Seeds numerous, obovoid to ellipsoid, minute; seed 
coat crustaceous, the cells of outer epidermis mucilaginous; raphe indis- 
tinct, the chalazal knot apiculate; embryo axial, stout, straight, sub- 
cylindrical, the cotyledons small, semicircular in cross section, nearly 
equaling the thick superior radicle. Type spectes: M. Calabura L. (Name 
commemorating Abraham Munting, 1626-1683, professor of botany in 
Groningen, Nederland, and author of several botanical works. ) 


The single species, Muntingia Calabura, widely distributed in the West 
Indies and from southern Mexico to Peru, northern Argentina, and Brazil, 
has become established in pinelands and hammocks (e.g., Sisal Hammock) 
in Dade and Hendry counties, Florida. Its further spread seems likely, 
for the ability to reproduce vegetatively and a tendency to become weedy 
have been recorded for the species. 

The solitary flowers or fascicles of two or three flowers which develop 
in a sequence are derivable from the simple, peduncled dichasia which are 
sometimes encountered in the species. The floral anatomy, in general, is 
similar to that in Tiliaceae and in Elaeocarpus (Rao). The lack of one 
stipule seems to be correlated with the absence of one stipular trace 
(Sensarma). 

The taxonomic position of Muntingia is uncertain. The embryo develop- 
ment is of the Onagrad type, which seems to be otherwise unknown in the 
Malvales. The smaller pollen and the absence of mucilage cavities in the 
axis and leaves suggest that it should be retained in the Elaeocarpaceae. 
However, the microscopic structure of the wood differs from that of the 
other genera of Elaeocarpaceae, but is very similar to that in Dicraspidia 
Standl. and has many points in common with other Tiliaceae (Metcalfe 
& Chalk). The structure of the leaf and inner bark, resembling that in 
Tilia (cf. Dumont), also seems to indicate a closer relationship to Tiliaceae 
than to Elaeocarpaceae. The genus is undoubtedly closely related to the 


1965] BRIZICKY, TILIACEAE & ELAEOCARPACEAE 307 


monotypic Dicraspidia (D. suns? ae ), which is known from 
Honduras, Costa Rica, Panama, and Colom 

Grown as an ornamental in many ae and aig sas countries, 
Muntingia Calabura often becomes naturalized. Fibers from the inner 
bark are used locally for making cordage and in basketry.

rather to Tiliaceae, if these families are to be combined. In general aspect, and in 
a, leaf form, and gross appearance of the flower Muntingia and Dicraspidia 
very similar, so much so that their relationship can scarcely be questioned.” 
fecal & Chalk (p. 265) noted the similarity of the two in wood structure, which 
is different from that of the rest of the Elaeocarpaceae. Dicraspidia, in turn, doubtless 
is closely related to the monotypic eastern Peruvian MNeotessmannia Burret, the

Tiliaceae. That these genera are monotypic seems to indicate the saunas of the

POLLEN OF DEGENERIA VITIENSIS 


A. OrvitLe Dani! AND JoHN R. Rowtey ” 


SINCE THE ORIGINAL DESCRIPTION of the uncommon, monotypic genus 
Degeneria of the family Degeneriaceae by Bailey and Smith (1942), 
additional collections of flowering and fruiting material throughout its 
known range in Fiji have been made by Smith (1949). Swamy (1949), 
in his careful morphological analysis of the family, included a description 
of the microsporangium and microspores derived from Dr. Smith’s collec- 
tions. 

This paper is a summary of additional observations made on microspore 
and pollen material utilizing primarily the techniques of phase contrast 
microscopy in association with electron microscopy. 


MATERIALS AND METHODS 


All observations were based on preparations made from specimens col- 
lected and preserved in Fiji by Dr. A. C. Smith. The field collections 
available for use were Dr. Smith’s numbers 5744, 5875, and 5880. The 
reagents used for fixation were limited to formalin-acetic acid-alcohol 
(FAA) and, in one instance, to potable spirit (gin). Despite the poor 
over-all state of preservation for purposes of electron microscopy, data on 
our preparations are reported in view of the present scarcity of material. 

Microspores and mature intact pollen grains were mounted from the 
preservative into various media (cf. Bailey, 1960; Dahl, 1952). Precise, 
but impermanent, staining of pectic components of apertural membranes 
was attained by mounting the specimens in filtered 0.2% ruthenium red in 
75% aqueous glycerine (Mangin, 1893; Bailey, 1960). The slides retained 
specificity of reaction for a period of up to ten days when stored in a 
refrigerator. 

Material was mounted, either directly or after extracting aie aa 
in lactic acid (ca. 85%) or media based largely on this reagent (e.g. 
“lactic-iodine” made by combining 1 part of 1% iodine and 1% potassium 
ae in 80% ethanol with 3 parts of lactic acid, or “lactic- triacetin” 

work was supported in part by funds from the National Science Foundat 
(Grant G9973) and the National Institute of Allergy and Infectious Diseases, risk 
Institutes of Health (Grant E3989). Grateful acknowledgment is made to Professor 
I. W. Bai Dr. A. C. Smith for preserved material of Degeneria. Professor 
Bailey generously provided research facilities during part of this study. In addition, 
Dr. Johs. Iversen kindly made research facilities sabato in his laboratory at Dan- 
marks Ge ne giske Undersggelse, Charlottenlund, Denm

composed of 4 parts lactic acid and 1 part triacetin, or “lactic-butanol” 
prepared by combining 4 parts of lactic acid with 1 part of n-butanol). 
Such non-hardening media require sealing of the cover glass with a rela- 
tively inert varnish such as the phenolic “Tuf-On” #74 varnish (obtained 
from Brooklyn Paint & Varnish Co., Inc., 50 Jay St., Brooklyn 1, N.Y.). 
Preparations that did not require sealing were obtained by mounting the 
material in a variation of Downs’ (1943) polyvinyl-lactophenol mixture 
designed to attain much of the favorable optical characteristics of lactic 
acid, This variation is made up of 3 parts lactic acid, 2 parts 15% aqueous 
polyvinyl alcohol (medium viscosity), and 1 part phenol. 

Pollen grains badly darkened by the preserving fluid were partially 
cleared when mounted in 70% aqueous chloral hydrate. Such mounts 
were satisfactory for phase contrast analysis. 

A desirable optical environment for purposes of phase contrast analysis 
of sections of methacrylate-embedded specimens with the embedding 
medium still present was maintained by mounting the sections in a drop 
of a 1:1 mixture of poppyseed oil and -butanol followed by sealing of the 
cover glass. For ordinary microscopy, similar sections of methacrylate- 
embedded microspores were mounted in the lactic acid-iodine medium. 
After sealing, these preparations revealed the familiar yellow-stained cell 
walls and purple-stained starch grains in an optically suitable environment. 

Pollen grains were treated with Novopokrowsky’s (McLean & Cook, 
1952) chloroiodide of zinc for observation of apertural structures. 

Microscopical observations were made with apochromatic (Leitz, N.A. 
1.32) and fluorite phase (Leitz, N.A. 1.15 and Wild, N.A. 1.30) objectives. 

Electron microscope preparations were obtained from osmium tetroxide,

1960) embedded in methacrylate or the polyester copolymer “Vestopal 
W” (Ryter & Kellenberger, 1958). 


OBSERVATIONS 


Microspore Stages. During the quartet stage of telophase II of 
meiosis, a callose wall up to ca. 2.5 » in thickness bounded each group of 
microspore protoplasts. ey early microspores in the available quartet 
stages did not have an exin 

The youngest available nen (Fic. 1) bounded by exine were at 
a pre-mitosis stage. The exine was fully developed and continuous over 
the entire microspore surface. The outer surface of the exine was smooth 
while the inner surface was fimbrillate (Fics. 5-7). An incipient aperture 
was differentiated but not expanded. In thin sections, the exine was found 
to taper gradually in thickness as it extended from proximal regions of the 
pollen grain to the apertural margin where exine of minimal thickness 
occurred (Fic. 5). Over the incipient germinal aperture, the exine was 
undulate and was 3 to 5 times thinner than in nonapertural regions (Fics. 
8 & 9). Intact microspores at this stage were about 40 to 44 » in diameter 
with a perimeter of 125 to 135 » (Fic. 1).

. 1-4. In Ficures 1 to 3 the dimensions and form of the components 
of these composite drawings were obtained from camera lucida drawings and 
electron micrographs. Magnification, as reproduced X %%, ca. 1,100. 


There was an intine-like, low density layer 0.4 to 0.05 » in thickness 
under the nonapertural exine. At the aperture, the intine-like material 
took the form of a thick, lens-shaped layer which showed localized dense 
channels or pockets of material (Fic. 8). This layer was rapidly and 
differentially stained with ruthenium red precisely as was the case in the 
apertural intine of the mature pollen grains. 

In addition to the well defined exine and a translucent intine-like layer 


1965] DAHL & ROWLEY, POLLEN OF DEGENERIA 311 


there were several dense lamellae between the exine and the presumed 
intine (Fics. 6 & 9). 


Mature Pollen Grain. The germinal aperture formed the only dif- 
ferentiated feature of the psilate pollen grain. The aperture extended over 
the distal surface to a point below the equator. At the distal pole, the 
aperture was usually constricted while its ends were enlarged (Fic. 4). 
A distinct but irregular exine margin was visible at an upper focal level 
with phase contrast microscopy. At a lower focal plane, a well delimited 
layer broader than the exinous opening ran the length of the furrow. This 
was made conspicuous with the ruthenium red reagent. In surface view, 
the layer appeared foveate, whereas in optical section it presented a 
columellate or striate appearance (Fics. 10 & 11). 

The aperture of pollen treated with Novopokrowsky’s chloroiodide of 
zinc for ca. 30 minutes was striking in its greenish color and clearly re- 
vealed in the Zwischenk6rper relatively fine structure having a striate 
appearance. In equatorial views of such pollen grains, the generative cell 
was usually close to the proximal pole, whereas the tube nucleus, while 
adjacent, was closer to the distal pole. The generative cell is about 12 » 
in diameter with a nucleus 6.7 » in diameter and a relatively inconspicuous 
nucleolus approximately 1.6 » in diameter. In contrast, the tube nucleus 
is approximately 10 » in diameter having a relatively conspicuous nucleolus 
some 5 p» in diameter. 

We obtained positive reactions for cellulose in a thin layer bounding 
the protoplast but with the available specimens the microchemical tests 
were frequently imprecise and difficult to interpret. With Novopokrow- 
sky’s iodine-zinc chloride treatment a greenish coloration appeared, while 
a slight bluish-green reaction occurred in the intine when iodine-potassium 
iodide followed by 65% sulphuric acid were used. After bleaching with 
30% H2O2 some of the pollen grains badly darkened by long storage in 
fixative gave, with the IKI-H2SO, procedure, a purplish reaction possibly 
Suggestive of cellulose at the surface of the protoplast. In unfixed pollen 
of Liriodendron, these procedures resulted in the typical blue cellulosic 
reaction in the inner intine of many grains. Bailey (1960), Martens and 
Waterkeyn (1962), et al. have reported the characteristic presence of 
cellulose in inner intine in a wide range of taxa including Magnolian and 
Ranalian species. Final decision on its occurrence in Degeneria can best 
be made with additional observations on fresh material. 

In electron micrographs of pollen stained with osmium tetroxide and 
embedded in methacrylate, the intine was seen to be composed of two 
zones (Fics. 2 & 15). The inner zone was comparatively uniform in tex- 
ture. Near the terminus of the aperture this zone had an internal thicken- 
ing or bulge (Fics. 12 & 15). In nonapertural regions, the outer zone 
consisted of strands which graded into material of spongy appearance in 
the apertural part of the pollen grain (Fic. 15). 

The appearance of the intine of pollen grains embedded in “‘Vestopal” 
following staining with osmium tetroxide, uranyl acetate or potassium

permanganate differed from the above in lacking a stranded inner zone 
(Fics. 14 & 17). Analysis of sections before and after removal of em- 
bedding matrix and shadowing showed that the spongy part of the intine 
was composed of ramifying channels within the outer subdivision of the 
intine (Fics. 15 & 16). In sections, the channels contained a dense sub- 
stance (Fic. 17). Such channels were also visible in electron micrographs 
and phase contrast photomicrographs of the germinal aperture in Lirioden- 
dron pollen fixed in osmium tetroxide or potassium permanganate (Fics. 
18-21). 

In the early formation of the apertural intine of Liriodendron, strands 
of microspore cytoplasm penetrated directly into the spongy structure 
(Fic. 18). Elements of the endoplasmic reticulum were seen to extend into 
the channels (Fic. 19). The inner zone of the intine was introduced at a 
later stage of development (Fics. 20 & 21). 

During maturation of the aperture in the pollen grain, cytoplasmic 
strands crossed the inner zone of the apertural intine and connected with 
the substance in the channels of the outer zone (Fics. 20 & 21). When 
Liriodendron pollen reached maturity the channels still contained dense 
material, but connections with the cytoplasm through the inner part of 
the intine did not persist. Sections of Liriodendron, used for phase con- 
trast microscopy, showed continuity of the material within channels of the 
intine and the cytoplasm (Fie. 13). 

In sections of Degeneria anthers, small round bodies (0.44 to 0.55 p in 
diameter) having a density the same as the exine, some with an eccentric 
cavity, were seen between the locule wall and the pollen wall (Fic. 15). 





DISCUSSION 


In its complex of pollen characters, Degeneria has natural alliance with 
Magnolian taxa (Bailey and Smith, 1942; Swamy, 1949). The single 
distal aperture is a familiar basic character. The following distinguishing 
characters were observed in pollen of Degeneria: a narrow furrow extend- 
ing over the distal hemisphere and ending somewhat below the equator in 











(Note: beginning with ricure 5, the black scale line on the electron micrographs 
is equal to one micron.)

the proximal hemisphere; a dumbbell-shaped aperture caused by an in- 
crease in the width of the furrow in the equatorial region; an extremely 
thin exine covering the distal surface with the exception of the narrow 
aperture; and a smooth and internally amorphous exine even at magnifica- 
tions of the order of 30,000 times. Many pollen types described as psilate 
are found to be ornamented as improved methods of observation can be 
applied, but Degeneria offers an example of an exine that is truly psilate. 

The remarkable sponge-like apertural structure (Zwischenkdérper, 
Fritzsche, 1837) of Degeneria pollen is portrayed in the electron micro- 
graphs used for ricGuREs 15, 16, and 17. The channeled Zwischenkorper of 
Degeneria microspores and pollen grains is similar to apertural structures 
observed in Liriodendron tulipifera (Fic. 20). In Liriodendron prepara- 
tions it is clear that the channels which are isolated in the Zwischenkérper 
in mature pollen were part of a system of cytoplasmic strands connecting 
the wall with peripheral cytoplasm of the microspore during early stages 
of development (Fics. 13 & 18). As in Liriodendron, the Zwischenkérper 
of Degeneria was quickly responsive to specific ruthenium red staining. 
In microspores and mature pollen of both genera the ruthenium red 
reagent sharply differentiated the Zwischenkérper as a channeled ribbon- 
like structure. The red-violet ruthenium red coloration usually first 
appeared in equatorial regions of the germinal furrow, and the color 
was deeper there than in the distal region. Presumably, areas of intense 
coloration following ruthenium red staining were loci of high polyuronide 
concentrations (Bailey, 1960) and were related to the system of cyto- 
plasmic strands. In Dr. A. C. Smith’s collection No. 5880 we found 
grains with pollen tubes in various stages of emergence. Pollen tubes 
were also reported for this material by Swamy (1949). The pollen tubes 
we saw had gained exit at the ends of the germinal furrow in the region 
giving the most intense reaction to ruthenium red. The exine bounding 
the apertural area tapered to a thinness of 10-50 millimicra over the 
Zwischenkérper (Fic. 15) and was difficult to separate from the Zwischen- 

Orper in our electron micrographs (Fic. 16). Evidence for an exine-like 
covering over the distal surface comes from LO analysis of intact pollen 
and the resistance of material in that part of the wall to acetolysis. In 
mature grains stained with potassium permanganate, the exine seemed to

between the exine and intine continued out over the intine. The lateral 


per 
illustrates the above relationships of the homogeneous exine, intine, and 
dense middle materia 
Exclusive of the thin exine-like material over the Zwischenkorper, the 
area of the exine is only slightly greater for mature pollen than for micro- 
spores. Accommodation for the increased surface area demanded by the 
greater volume of the protoplast of mature pollen, as shown in FIGURES 
1 and 2, seems to reside in the thin cover over the Zwischenkorper and the 
expanded ends of the aperture. The thin exinous covering of the apertural 
region must originate either by stretching of existing exine (perhaps the 
folded covering seen in presumptive apertures of microspores in FIGURE 
8) or by proliferation from new sporopollenin between the microspore and 
mature pollen stages 
For Degeneria there is little evidence for deciding between the alterna- 
tives, stretching of existing exine or deposition of new sporopollenin. The 
fimbrillae of the inner exine surface change slightly in form from the 
microspore stage to mature pollen (Fics. 6 & 14), tending to be more 
widely spaced and shorter in the mature exine. This phenomenon could be 
used with equal justification to argue for expansion of the entire exine 
cover or addition of new sporopollenin. Addition of at least some new 
sporopollenin to the exine following attainment of exine final form, prior 
to microspore mitosis, was reported for pollen of Poa annua (Rowley, 1962). 
But evidence is also available to support modifications in exine form by 
expansion of the exine. Kuprianova (1948) proposed that the differences 
in pollen size and shape in the Commelinaceae were largely the product of 
variation in the amount of expansion of the apertural part of the grains. 
In mature grains of Pollia, Floscopa, and Commelina, Kuprianova’s illus- 
trations suggest expansion of apertural ornamentations from a system like 
the nonapertural part of these pollen grains. In Commelinantia anomala, 
where conditions for determining the stage of development and fixation 
were more satisfactory than for Degeneria, we have made some deductions

which parallel Kuprianova’s suggestions and may be partially applicable 
to formation of the thin exine bordering the Degeneria aperture (Rowley 
& Dahl, 1962). In C. anomala, insulae bisected by the aperture margin 
had the appearance of apertural insulae at one end and nonapertural 
insulae at the other with indications of deformation by stretching in the 
middle regions. The endexine was reduced in height in the middle region 
from about 500 to 50 millimicra, concomitantly going from a sheet to a 
network, and the tegillar ends of columellae were tilted toward the aper- 
ture. We feel that these effects could be produced by movement of the 
apertural ends of insulae bisected by the aperture margin toward the 
aperture. The proximal ends of columellae around the periphery of aper- 
tural insulae splay outward and augment the notion that tension could 
be responsible for the tilting of columellae and conversion of endexine 
from a sheet to net form. 

It may seem self evident that new sporopollenin would be added 
throughout the period of exine enlargement, but there are observations 
which suggest that the addition of new exine material is either stopped or 
does not keep pace with the area increase required by volume changes 
in the pollen protoplast during final maturation. In work with pollen of 
the Amaranthaceae Kajale (1940), for example, noted that the exine in 
mature grains was thinner than in earlier stages apparently due to its 
being stretched by protoplast growth. 

Round bodies were seen in Degeneria anthers between the tapetum or 
locular wall and the male gametophyte in quartet, microspore, and mature 
pollen stages. These bodies frequently had central or eccentric openings 
of low density which in mature stages were found to be empty cavities 
after removal of the embedding material and shadowing with heavy 
metals. These exine-like bodies are similar to the tapetal secretion drop- 
lets, orbicules, or Ubisch bodies described or reviewed by Maheshwari 
(1950), Erdtman, et al. (1961), Heslop-Harrison (1962), Takats (1962), 
and Rowley (1963). In Degeneria, these orbicule-like bodies exhibit the 
psilate surfaces characteristic of the mature exine. It appears possible that 
some association exists between orbicules and the mature exine in the 
character of the ornamentation of the respective surfaces. 


SUMMARY 


Based upon material fixed by Dr. A. C. Smith in Fiji, the mature pollen 
wall of Degeneria vitiensis I. W. Bailey & A. C. Smith is psilate and tapers 
gradually from the proximal surface to a thin edge in the apertural region. 
The exine is internally amorphous. The inner surface is not smooth like 
the outer but fimbrillate. The intine is subdivided into an extensive lens- 
shaped Zwischenkérper, an outer part limited to the apertural region, and 
an inner part that envelops the cytoplasm and has but one distinguishing 
feature, a longitudinally oriented bulge parallel with the aperture and 
protruding into the cytoplasm. Ramifying channels in the Zwischenkérper 
contain a dense material. Several photomicrographs and electron micro-

graphs of pollen of Liriodendron tulipifera are included to demonstrate 
continuity of the dense material in the Zwischenkérper with the pollen 
cytoplasm in that species. 

Quartet and late microspore stages are compared with mature pollen 
grains of Degeneria to suggest the mode of aperture differentiation and 
sequence of formation of the intine subdivisions. A dense material was 
seen between the homogeneous exine and the intine in both late micro- 
spores and mature pollen. Round exine-like bodies seen between the wall 
of the pollen grain and the tapetum or locule wall may be orbicules.

It is a long time since I have had any word from you. I hope you have 
not, like most of the rest of the world, given yourself up to raising potatoes 
and cabbages. There is too much botany left to be finished in Louisiana 
for that. I shall be glad to hear what you have seen and accomplished 
since you last wrote.

I do not understand why we overlooked this tree when we were at 
Hammond, but I suppose we were busy thinking of other things. 

How about the small Live Oak which we saw there on the prairies? 
I hope you won’t fail to get the fruit.

Glad to get your letter even if it is written from such a place as Berlin. 
I am glad that you will undertake the Opelousas and Springfield Oaks and 
I am counting on you to do this. I hope you will get specimens of the Oak 
with rhomboidal leaves. 

You say that I have flowers of the Lake Charles Linden, but I haven’t 
flowers, only young buds, of the Linden of which I need material, that is 
the tree at the ferry in West Lake Charles. If you have ever collected 
flowers of this I hope you will let me have them. This you know is the 
tree which has puzzled us a good deal and which we thought last spring 
was different from any of the other Louisiana Lindens.

Is there any chance of your being north this summer? 

P.S.— Do you remember that Carya alba-like tree by roadside near 
Loringer with slender branchlets and very tomentose young leaves? I 
judge that the Winnfield tree which has so long bothered us is the same 
and I have specimens of what I take to be the same thing from Natchez. 
This is a tree which needs investigation. It may be only a variety of alba 
but it is unusual and we need mature leaves and fruit. 


151 
August 27, 1917. 
I have yours of the 23rd and the specimen of Quercus, for which many 
thanks. This is not a straight rkombifolia but may be a form of it with 
lobed leaves. Notice the long-stalked fruit. I hope you will get specimens 
later and if possible find more trees. 
There are no end of forms apparently of these southern Oaks. What 
should you think of the proposition of referring everything from Louisiana 
which has been called /aurifolia to forms of Q. nigra? 


152 
October 27, 1917. 

I am delighted with your bundle of specimens. The leaves of Quercus 
geminata are much thicker and more prominently veined than those of 
Q. virginiana. The Louisiana Live Oak is like the type as known to 
Catesby, Linnaeus, etc. 

Quercus geminata, which is described as a small tree, by Small, is at 
Biloxi a large tree, as large as the common Live Oak with which it grows. 
It often has solitary fruit just as the typical Live Oak has the fruit in pairs, 
in threes or in fours in spite of anything Sargent’s Manual may say. 
Quercus virginiana and Q. geminata seem to run together and I am going 
to consider the latter a form of the former. Small and Britton evidently 
got the two a good deal mixed up. I have not seen Quercus geminata 
from Louisiana or Texas. : 

We have no specimens of Q. myrtifolia from Louisiana and it should 
be dropped from the state unless we can get some real evidence of its 
occurrence there. The Chandeleur Islands are where it might be expected. 
Do you know anything of these Islands? I regret to say that we have no 
specimen from the Islands in Mississippi Sound on which this plant is 
reported to be very common. How can one be obtained? 

Is your Quercus No. 4334 from Opelousas one of the trees with scaly 
bark in the low ground near Washington? This number seems to be the 
only one which has fruit. It may be hard to distinguish this specifically 
from the Post Oak, but it is evidently a distinct variety and a very fine tree. 

Quercus No. 4716 near Hammond, Sargent and Cocks, in the spring. Is 
this from the small tree on the prairies with pale bark and slender drocping 
branches? If so, it seems to be an undescribed and interesting form of the 
Live Oak. Your small shrubs seem to be the same, so I suppose it is both 
a tree and a shrub. 


326 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


I am glad to get the acorns of Q. repanda. I suppose it is undoubtedly 
a form of the White Oak, although the acorns do not look much like white 


corns. 

I should think now that we had Louisiana trees pretty well cleared 
up with the exception of Crataegus and the thin-branched, small-budded 
form of Carya alba. Have you been able to do anything about that? It 
grows near Hammond and at Wakefield near the quarry. I wish I knew 
more about this tree. I suppose you will have sometime specimens of 
Carya pallida from near Alexandria for me. 

I hope your health is restored and that you have at last partially re- 
covered from the shock of living in a town called Berlin. Did you come 
north this summer at all?

Glad to get your letter of October 31st with information about the Oaks. 

In regard to the Washington Oak I do not think it can be a hybrid, at 
least I can see nothing of Quercus alba in it. Quercus Margaretta is 
nothing but a Post Oak with the lobes of the leaves rounded at the ends. 
Such leaves with rounded lobes and others with the ordinary square lobes 
occur on the same tree and often on the same branch. 

The dwarf Post Oak from Selma I want to call forma stolonifera of 
Q. stellata. The Hammond 4716 is certainly a very distinct form 0 
Q. virginiana and might almost be called a species. 

The Oak with rhombic leaves I have described as Q. nigra var. rhombi- 
folia. I am not sure, however, after seeing your Alabama specimens if it 
should not be called a species. It certainly has more to do with nigra than 
with the Laurel Oak which has smaller, much thicker leaves which become 
much lobed on vigorous young shoots. My idea now is that the Laurel 
Oak does not get into Louisiana 

I have n’t been to look at the Lindens yet. I want to wait until the whole 
season’s collecting is in before tackling the annual job. I was in hopes I was 
going to finish it this year, but there is certainly an undescribed Linden 
near Raleigh, North Carolina, and apparently another at Charleston. 
Certainly there is no end to them.

I do not know what to say about your hybrid Selma Oak. If Quercus 
imbricaria occurred in that region I should guess that it was one of the 
parents, but we have no indication here that Q. imbricaria reaches Alabama 
at all. My guess would be that Q. marilandica is one parent and the other 
may be nigra. Such determinations of hybrids, unfortunately, are almost 
always pure guesswork and one person’s guess is as good as another. 

Any word yet of that thin-branched Carya alba?

I have been in Florida for a few days looking at Quercus laurifolia, etc., 
and returning here find yours of the 3rd. 

I am sorry that we are still short of that Wakefield Hickory which if it 
is a form of Carvya alba, is certainly interesting. 

Yes, I know H. S. Dawson who is the son of a man who for many years 
was Superintendent of the Arboretum. There are few people probably 
in the United States who are less fitted for intelligent planting in Louisiana 
as he knows nothing of the southern vegetation. Ness I know about, that 
is if he is the Professor at the University of Texas who has raised a 
Quercus virginiana lyrata hybrid which is identical with our Natchez 
tree.” I am more than ever convinced that Q. laurifolia has not been col- 
lected yet in Louisiana. It grows in Mississippi City on the Sound and if it 
was anywhere in Mississippi it would be in the Hammond region which 
ought to be examined further for it. I will send you one of my Florida 
specimens in a few days to guide you in any hunt you may undertake. 


156 
December 24, 1917. 

The Lake Charles Oak which we called [Quercus] laurifolia I take to be 
Q. rhombifolia. There is no fruit. I am placing with Q. rkombifolia also 
Palmer’s 8487 from Welsh, your Mandeville specimen 4698, your Pineville 
specimen 4702, although this last may be a hybrid, your Springfield March 
1917 (type), and your 4710, your Slidell 4708 and your Sardis 4706, also 
4712. I think we shall have to consider this a species. 

I have a leaf specimen of Ness’s /yrata % virginiana, hybrid, and a 
photograph of the fruit produced by his plant and they seem identical with 
the Natchez-New Orleans tree. It is a wise parent who knows his own 
offspring. 

Please do not forget that you are going to send me specimens of Carya 
pallida from near Alexandria. 

Louisiana Crataegus. I have been talking with Harbison about the 
species of Crataegus which he discovered near Opelousas. Cocks’s 39 from 
Natchitoches equals C. edura Beadle. We have Beadle’s cotype but you 
and I do not appear to have collected this species near Opelousas. 

C. albicera, We have a cotype collected one mile south of Opelousas in 
fruit. We do not seem to have collected it. 

C. coccinea. We have a cotype collected seven miles west of Opelousas. 
We have n’t collected this. 

C. tersa is our No. 2 from west of Opelousas, April 4, 1913. Your un- 
numbered specimens of April 1914 and my specimens in fruit of Nos. 3 
and 6 of October 1913 are this species. 

Beadle writes, —“I see by my notes that it is C. albicera that has 


Ness, H. Hybrids of the live oak and overcup oak. Jour. Heredity 9: 263-268. 


328 JOURNAL OF THE ARNOLD ARBORETUM [ VOL. 46 


pure yellow and edible fruit. Under this species I said in fall of 1901, 
‘large yellow fruit, just getting ripe, acid, good to eat.’ The type tree is in 
low woods seven miles west of Opelousas. C. crocinna [sic] is another 
yellow one ripening its fruit about a month later than that of C. albicera. 
This grows in the same low woods west of Opelousas. C. edura and C. 
tersa have red or ruddy fruit, not edible. These trees grow in upland woods 
and I think the type trees are within half a mile of Opelousas. I am not 
positive, however, having no record of the number of the type trees. South 
and east of Opelousas was a large enclosure used for pasture. In this 
enclosure is where I first found these species. I went along the Railway 
in the direction of Lafayette half a mile or less and climbed the wire fence 
and back in this woodland pasture is where I found the trees. There must 
be some C. albicera in the vicinity of Opelousas for I found yellow fruit 
under a C. edura tree and collected it by mistake, afterwards learning 
from a boy that he and other boys pelted some girls with yellow haws 
while they were sitting under that tree eating grapes.’ 

Really a yellow-fruited Crus-galli species is rare. I certainly never went 
to this station south of Opelousas which Harbison talks about and I 
wonder if you have been there. This might be a good place to visit some- 
time if you want to get material of these Hawthorns. 

With best wishes for the New Year, I am,

January 16, 1918. 

I have been looking at Oaks lately and think that Palmer’s 7448 and 
7473 Natchitoches are only a large-leaved form of Q[wuercus] nigra. 

Quercus 1002, Sardis, is I think marilandica  velutina, a common 
hybrid which is not rare & is widely distributed. I think of calling this 
Q. Bushii as it appears to have been first collected by Bush. 

Cocks’s 4702, Pineville, April 1917, looks like a hybrid between 
rhombifolia and velutina. Did you get it again in the autumn? Fruit and 
mature leaves should be collected. This seems to be quite a new hybrid 
and looks interesting. 

Cocks’s Selma 4704. For a guess this may be a Catesbaei and nigra 
cross, and to this cross Trelease has given the name of Q. Walteriana 
ined. I am not entirely satisfied with this guess, but Catesbaei is surely 
one parent. 

Have you ever made that trip to the Chandeleur Islands? 

I am sorry to see that you are having very cold weather with snow at 
New Orleans, and I am afraid there has been a good deal of damage done 
to plants. This has been the worst winter here I can remember so far as 
cold is concerned but we have n’t had yet much snow. I hope you are well.

The Oak Ashe has tried to write you about is his Quercus rubra var. 
leucophylla. 1 enclose a copy of his original description from the Bulletin 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 329 


of the Charleston Museum.'® This Oak has long troubled Harbison and 
me, and I am glad that Ashe has made what seems to be a good disposition 
of it. The only Louisiana specimens I have seen are Palmer’s Natchitoches 
7443 and Welsh 8486, Cocks’s Mandeville 1787, May 1908, as Q. pagodae- 
folia. I collected it at Lake Charles April 13, 1915, and the only Selma 
specimen I have seen is Harbison’s #20 “in woods west of the city, April 

if Tig 

I never told Ashe that it was the largest tree in the swamps in any part 
of Louisiana for I have seen very little of it in your state. What I did tell 
him I think was that it was one of the largest trees in the swamps about 
River Junction, Florida. 

The Springfield tree I am describing as Q. rhombifolia. I am glad to 
know that it holds its leaves later than nigra. 

How about this evergreen Q. Phellos you speak of? Isn’t there some 
mistake, and have you not got hold of laurifolia which is evergreen and 
which has leaves a good deal like those of Phellos? 


159 
February 13, 1918. 

I shall write you in a day or two at some length about the Quercus 
situation in Louisiana and I am only writing today to call your attention 
again to your Oak No. 6 from St. Tammany July 1900. 

I cannot make anything out of this but Quercus borealis and Q. borealis 
is the most northern of the Atlantic Oaks and grows only in very cold 
regions. If your tree is really this species its presence in Louisiana is be- 
yond my understanding. This is a matter certainly for further investiga- 
tion and it will be interesting to know if this tree is common. 

In my Manual Quercus Catesbaei is credited to eastern Louisiana, but 
there is no specimen from Louisiana in this herbarium. There is no speci- 
men either of Q. cinerea from eastern Louisiana where it might be ex- 
pected. You ought to try and find some sandy region in Louisiana east of 
the river, for if you can I think you will find growing on it the thick- 
leaved Q. virginiana, Q. cinerea and Q, Catesbaei. 

We have only one specimen of Q. marilandica from Louisiana, Palmer’s 
No. 7517. There is no indication that this tree grows in eastern Louisiana 
and no specimen collected by you. We have no specimen of Q. Prinus 
(Michauxii) from western Louisiana, and no specimen of Q. rubra 
(falcata) from eastern Louisiana collected by you. We have no specimen 
of Quercus lyrata from eastern Louisiana and none collected by you or me 
in Louisiana. 

It looks to me as if more attention should be paid to eastern Louisiana 
for the determination of the distribution of Louisiana trees. There does 
not seem to be any reason why trees growing at Biloxi and Mississippi City 
should not cross the Pearl River if there is any sandy soil for them to 
grow in.

February 15, 1918. 

I have this morning your letter of the 11th with specimen of Quercus. 
The twigs to which you refer are not in the package and I suppose will 
arrive later. 

I never heard of the man Neal who has been appointed Superintendent 
of Audubon Park. 

Your evergreen Willow Oak from Sardis is, as I suspected, Q. /aurifolia. 
This makes a new tree for that apparently inexhaustible region. Quercus 
laurifolia is one of the best street trees in the world for the southern states 
and there is no better tree for New Orleans. It is worth going to Jackson- 
ville, Florida, to see the Laurel Oaks which have been planted there. 


161 
February 15, 1918. 

I have your note of the 24th and am now ready to report on the 
Louisiana Oaks. 

Quercus rhombifolia I find was used by Riddell for one of his species de- 
scribed in 1853 in the New Orleans Medical Repository, so I have substi- 
tuted rhombica for the new Water Oak. 

Post Oaks. 

There are two distinct forms of Post Oak, the first with stout tomentose 
branches and the other with slender glabrous or nearly glabrous branches. 
To the first group belongs the typical Quercus stellata with the upper 
lobes of the leaves broad and truncate or slightly lobed. To this I refer 
Palmer’s No. 8492, Welsh, and Natchitoches No. 8912. We collected it 
on March 29th last growing on dry ground near Springfield. Of the form 
with glabrous branches the most common and widely distributed is the 
variety Margaretta Ashe with usually rounded lobes to the leaves, gla- 
brous above and loose pubescent below, slender reddish branchlets and 
very close bark. From Louisiana I find only one specimen which seems 
to belong to this variety, Palmer’s No. 9465 from Chestnut, with young 
leaves only, and a specimen collected by Letterman at Shreveport July 
23, 1891. This variety grows at Selma and I am calling the little running 
Selma Oak Quercus stellata var. Margaretta {. stolonifera. 

I propose the name of Quercus stellata var. araniosa for the Post Oak 
with scaly bark and loose cobwebby tomentum on the lower surface of 
the leaves which have both square and rounded lobes. The numbers are 
Palmer’s 8770, Grand Ecore (type), 7518, 8769 and 9446, Grand Ecore; 
7978 and 8838, Chopin, and 7361 Natchitoches. I suggest the name 
Q. stellata var. paludosa for the Washington trees with scaly bark, making 
your No. 4734 the type. This variety is distinct in its scaly bark, in the 
shape of the leaves and in the close tomentum on their lower surface. 

I am afraid we must call your Sardis numbers 898, 912 and 940 the 
Scarlet Oak after all, much as I dislike the idea of a Scarlet Oak growing 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 331 


so far south. I suggest Q. coccinea var. tuberculata for it, making No. 898 
the extreme form of the type. 

On April 4, 1913, we collected in low wet woods west of Opelousas 
specimens of a large Post Oak with scale bark, hoary-tomentose branch- 
lets and square-lobed leaves covered below with yellowish brown tomen- 
tum. You collected probably from the same tree on April 3, 1916 (No. 
4022). The mature leaves and fruit of this tree have not been collected. 
On April 3, 1913, we collected in the same locality what must be another 
form of Post Oak, also with scale bark, the leaves with square lobes but 
sparingly pubescent below, and stellate-pubescent, not tomentose, branch- 
lets. You have n’t collected autumn specimens from either of these trees. 
but your Natchitoches specimen, October 1913, a tree with broad lobed 
leaves, might be the same as the second of these Opelousas Post Oaks, as 
may be Palmer’s Welsh 8491 in low wet woods. 

The Post Oaks west of Opelousas should be followed up this year for, 
with the exception of them and your Pineville hybrid, all the Louisiana 
Oaks which we have seen are now accounted for. Other hybrids will no 
doubt be found, and I confidently expect you to send me specimens of 
Quercus virginiana geminata and Q. laurifolia as these are common at 
Mississippi City and should reach the extreme western parishes. 

Most of the Louisiana Live Oaks are typical Quercus virginiana, but 
for the little Oak with pale bark and small leaves from the neighborhood 
of Springfield I am suggesting the name of Q. virginiana var. eximia. 
Your 4716 is the type. Other numbers are 4718, 4720, 4722 and 4726, 

The Live Oak with strongly reticulately veined leaves revolute on the 
margins and tomentose below I call Q. virginiana var. geminata. This has 
not yet been found in Louisiana but it is so common in southern Mississippi 
that I am sure you will find it somewhere west of the Pearl River. 

Quercus texana Shumardii is my name for the Texas Oak with shallow 
cups with often much thickened scales. It is Palmer’s Natchitoches 7442, 
8761, 8762 and 9420; Mooringport 9408; Grand Ecore 7522, 9451; 
Shreveport 9481; Lake Charles 8522; Lake Charles, collected by us April 
12, 1915, a tree one hundred and ten feet high. Cocks, East Opelousas, 
4020, Richland County, June 21, 1905. 

The variety with deeper cup-shaped or turbinate cups I call Quercus 
texana var. Schneckii. This we collected on the West Plantation April 14, 
1916, on the Fort Plantation (Nos. 1 & 2), April 13, 1916, on the Dessert 
Plantation April 14, 1916, near Laurel Hill, March 28, 1910. It is Palmer's 
8735, Windsor (very typical), Chopin 8835. It is your Richland No. 
1915, September 21, 1910, 89352; and our Monroe, October 8, 1913. 

I have no evidence that the variety Shumardii grows in Louisiana east 
of the river, but it is so common in Mississippi and Alabama I should 
expect to find it there. The typical Q. texana has deeply lobed leaves and 
small acorns with turbinate cups, and is found only on the limestone hills 
of central and western Texas. 

Quercus nigra var. tridentifera. I suggest this as the name for the Water 
Oak with leaves distinctly three-lobed at the apex. We collected it April 


$32 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


13th near Laurel Hill and this I consider the type. We also collected it 
at Lorenger March 30, 1917. You collected it in Audubon Park October 
1913, and I collected it probably from the same tree in Audubon Park, 
March 31, 1917. There is a well-marked small tree of this variety in the 
fence row by road (right hand side) leading from Selma to Sardis. 

Quercus rubra var. leucophylla Ashe in Bull. Charleston Mus. xiii. 25 
(April 1917). To this variety, which has probably been taken, without 
the fruit having been seen, for Q. velutina and sometimes for Q. pagodae- 
folia, I now refer your Quercus pagodaefolia (?), Mandeville 1787, May 
1908, our Lake Charles, April 13, 1915, Palmer’s Welsh 8486, and Natch- 
itoches 7443. This tree needs further investigation for its distribution in 
Louisiana. The leaves on upper branches are deeply lobed and pale-pubes- 
cent on the lower surface, but on lower branches they are less deeply 
lobed with usually five broad lobes, and are green on the lower surface. 
Harbison has noticed that the hilum of the seed is pink. 

Quercus rubra var. triloba Ashe is the name of the Spanish Oak with 
leaves three-lobed at the apex. There is no specimen of this variety here 
from Louisiana, but as it grows at Biloxi and near Natchez, I should 
expect to find it in eastern Louisiana. We have very little Quercus 
velutina from Louisiana, only Palmer’s specimens from Shreveport and 
Natchitoches, your West Feliciana 2600, May 15, 1915, your Richland 1, 
January 1908, and a specimen collected by Mohr at Shreveport November 
1880. None of these will pass for the variety missouriensis which should 
be looked for in western Louisiana as it grows at Fulton, Arkansas. I 
shall be glad of more Q. velutina to show its range in the state. 

Quercus Comptonae. I am giving this name to the Natchez Oak which 
we think is a hybrid between /yrata and virginiana. This is your tree 
which is in Audubon Park and in one of the New Orleans streets. Please 
give me the name of the street where we saw it. 

What do you say to calling your Selma 938 and 814 a cinerea and rubra 
cross? To this cross Trelease has given the name of Q. subintegra. I 
have placed it in that group. 

Quercus 4702. This is probably a rhombifolia velutina cross. It is 
interesting and I should like to see the fruit. This number I hope you 
will follow up. 

Please tell me if this Pineville is across the river from Alexandria. I 
have tried again to determine Riddell’s Oaks in the New Orleans Medical 
Repository but I can make nothing out of them at all satisfactory. Might 
not his rhombifolia from Alexandria be your 4702? 

I don’t find Alabama 968, but 938 which is subintegra Trelease. 

With our present knowledge of Louisiana Oaks it ought to be easy now 
to find out more about them, and especially about their distribution. I 
hope you will collect them whenever you have the opportunity. I do not 
think Richland Parish and the Arkansas border parishes have been 
sufficiently explored. Can’t you manage this? The parishes along the 
Pearl River also need a careful search. We need specimens of the shrubby 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 333 


Willow from Louisiana you have spoken to me about. I do not think we 
have it here. 
I shall have another go at the Tilias as soon as I have finished Quercus. 


162 
February 18, 1918. 
The Japanese Quercus which they are planting in New Orleans is 
Quercus glauca," a widely distributed species in Japan, China and the 
Himalayas. It is a very fine tree, of course, but not as good for New 
Orleans as Q. laurifolia which I wish they would plant there. Do you 
happen to know where they got Quercus glauca? I did not know that it 
was cultivated in the United States. 
I suppose that I told you our Malus No. 2 from west of Opelousas was 
M. [unpublished binomial for M. ioensis var. creniserrata|. I believe now 
that the Louisiana Malus situation has been cleared up. 


163 
February 21, 1918. 

I am glad to see by yours of the 18th that Quercus marilandica and 
Catesbaei grow in eastern Louisiana. I should like to have specimens of 
all the eastern Louisiana Oaks to show their distribution in the state. 
This is important with the commonest species, for it is impossible to 
remember the distribution of every tree without reference to the herbarium. 

I should think it possible that you could find Quercus laurifolia culti- 
vated in New Orleans. If it is there it would be an indication that it was 
brought from Eastern Louisiana, for I do not think that there are many 
nursery grown native Oaks planted in the south. 

I am proposing to call the Pineville hybrid which looks very distinct to 
me Quercus Cocksii as there does n’t seem to be anything better in 
Louisiana in the way of an Oak for that name. I hope you will get 
more material. 

I hope about the middle of April to get down to North Carolina for a 
few days, but I am very much afraid I shall not be able to see you in 
Louisiana this spring; but you will have enough to do without me. 

I have been working for two months on Quercus and am now going to 
take up Carya and Tilia again. 


164 
March 1, 1918. 
Tilia 964 Sardis I suppose is what we have called T. heterophylla. 1200 
Sardis has all the earmarks of T. americana, now to be called T. glabra, 
but I hate to believe that this tree grows in Alabama. Still this is not per- 
haps as remarkable as it is to find Q|[uercus| borealis in Louisiana. 
#1202 looks like 1200, except that the axillary tufts are wanting or 


“This oak, the commonest species in Japan, has evidently been lost in the New 
Orleans area. 


334 JOURNAL OF THE ARNOLD ARBORETUM [ VOL. 46 


very small. With these I suppose belong Selma 822 equals 784, 6, 960 and 
several specimens without numbers collected by you in 1914. Also “Tilia 
americana,” Wakefield, West Feliciana, June 1907, and “Tilia americana” 
near Alexandria, June 1907. These last should be looked up and more 
should be known about them. 

1204 Sardis seems the same as 1202. 962, 970, 782 and 836 Sardis are 
all incomplete. 962 and 968 Sardis have loose pubescence on the lower 
surface of the leaves, that is it is easily rubbed off. I do not know what 
these are. Young leaves and flowers are desirable. 

There is still the tree by the Ferry at Lake Charles to complete. It is 
our +2 and flowers have not been collected unless your specimens from 
edge of Lake Charles collected May 10, 1911 but not numbered is that 
species. Some one has written on the label in pencil “referred to 4740” 
whatever that may mean. The leaves of this specimen have lost the 
lustrous bluish colors so conspicuous on the March specimens of #2. I 
judge that this Ferry tree blooms before the other species as the flower- 
buds on March 23, 1907 were pretty well developed. I think this must 
be an undescribed species. It is nearest, perhaps, to T. nuda but differs 
in the lustrous lower surface of the leaves and in its early flowers, for 
nuda seems the last of the Louisiana species to bloom. We badly need 
flowers and fruit of this tree. There are other #2’s about Lake Charles 
but I do not remember exactly where they are situated. I hope you can 
manage these this year. 

I do not know as it is any use sending Ashe any specimens of unpub- 
lished trees. He does n’t really want them, that is he does not maintain 
a herbarium, and it is just as well for him and others to wait until these 
questions are definitely settled and the descriptions printed. 

I hope you will let me hear that you can manage this Lake Charles 
business,

March 4, 1918. 
Since writing you about Tilias a day or two ago I notice that in your 
letter of October 20th you say you were sending the Lake Charles Linden 
from the edge of the lake by the ferry. I do not find this specimen unless 
it is the one in flower collected several years ago which I mentioned in 
my letter to you. It is astonishing how much trouble this tree gives us. 
— let me know about the specimen mentioned in the letter of October

I enclose leaves of a Bumelia collected by Palmer at Beaumont, Texas, 
which agree with the type of Small’s B. lucida 
You remember Bumelia lucida was credited to Louisiana by Small but 
I believe you have n’t found it there. As it grows at Beaumont [Texas | I 
should suppose the place to look for it would be in the Lake Charles region. 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 335 


167 
March 13, 1918. 

I have your letter of March 9th. It is hard for me to believe that your 
mounted specimen ‘Lake Charles, edge of the lake, May 10, 1911” is the 
Ferry tree. Notice that the leaves on the mounted specimen are decid- 
edly pale on the lower surface compared with your Lake Charles March 
26, 1911, which is green and lustrous below. This is our old No. 2 and I 
think is still undescribed. The mounted specimen looks to me like a 
[Tilia] nuda, We collected #2 March 26, 1911, April 12 and 13, 1915, 
and March 23, 1917. This tree has much larger leaves than those on your 
mounted specimen, slightly pubescent when they first appear especially on 
the midribs and veins, but soon become glabrous and are more lustrous 
on the lower surface than those of any species I know. 

I think many of our No. 2’s were collected down in that wood on the 
Lake Charles side of the river where we found so many big trees. If I 
am right in thinking your mounted specimen is a nuda, then we have no 
flowers whatever of No. 2 and no fruit of it at all. Evidently we have n’t 
got to the bottom of this business by any means. Is best you take this up. 

Since I wrote you about Oaks I have again reviewed the Quercus 
texana business and have reached the conclusion that it is perhaps best 
to separate Shumardii from texana. Geographically the species are dif- 
ferent and there seems to be pretty constant characters in the winter-buds 
and color of the branchlets by which they can be separated. Under this 
new plan the Louisiana trees are Q. Shumardii with shallow cup and 
Q. Shumardii var. Schneckii for the tree with deeper cups. 

What appears to be Celtis georgiana, which I think is nothing but Celtis 
pumila, has been discovered by Palmer in Texas, and as it is a common 
tree in the southeastern states I should expect it might turn up in Louisi- 
ana; at any rate it would be well to make a special attempt to collect 
Celtis in Louisiana. We have no Celtis material other than that collected 
by Palmer in the western part of the state. There is no Celtis here from 
eastern Louisiana collected by either you or by you and me together. 

What are you doing about Quercus myrtifolia? I hope you are not 
going to have a spring frost to destroy the growth of the early spring.

I can help you very little with your Louisiana Crataegus. The species 
from Holtonville, 2496, is C. silvicola Ashe. I do not know why I have 
never thought of this before. Perhaps the fact that this species has been 
found at Jackson, Mississippi, attracted my attention to it. As you 
know, the flowers of this have not been collected. 
Crataegus opaca Hooker. I am not sure that I have told you that this 
is the name for the Louisiana tree which has been called C. aestivalis. 
We ought to have specimens from western Louisiana.

The Lake Charles Crus- omg species in yard on road to the river from 
the town is C. Bushii Sar 

C. edita oe Nabe, Bush +4, April 1, 1909, Cocks xvii. 
April 24, 1912 

Crus- galli species, stamens 20; anthers white; “high ground.” Lake 
Charles, C. S. Sargent, April 10, 1915, is C. uniqua Sargent in Trees and 
Shrubs, ii. 237. This is a rare species originally from Marshall, Texas, 
and a good Louisiana find. 

Palmer, Natchitoches No. 10 (7291 and 8721) is C. fera of Beadle. 

I want to call your attention to the following: 

Cocks, Pineville, Crus-galli species just out of flower April 5, 1912. 
Flowers, color of the anthers and fruit needed. 

Crus-galli species, flowers April 24, no year, fruit not dated. Color of 
anthers needed. These two Pineville species look distinct. 

Cocks, Crus-galli species, Natchitoches xii., xiii. and xvi., April 24 and 
25, 1912, equals Palmer 7290, 8722, 9440. These all seem the same and a 
new species with twenty stamens and yellow anthers, a rare combination. 

A Crus-galli species collected by us in low woods, West Lake Charles, 
March 23, year not on the label, 1917? This has ten to twelve stamens 
and pale rose anthers. I do not find any other Louisiana specimen like 
this. Do you remember the tree? Fruit is needed. 

In August 1901 Bush collected at Minden a sterile branch of a distinct 
looking Crus-galli species ‘‘on right side of road to prairie west of town, 
in woods close to road, about three and a half miles from town and be- 
yond spring.” He collected another Crus-galli near Minden at the same 
time of which he says, — ‘‘Common in woods.” I collected at Minden on 
April 15, 1901, a Crus-galli species in flower but made no notes on the 
color of the anthers. Is not Minden a place to explore? 

Westfield Crataegus. +1, stamens twenty, anthers rose. This is the 
tree with very narrow leaves near the quarry and a new species. #2, 
stamens twenty, color of the anthers not noted. Is this the Crus-galli 
species we studied on the right-hand side of the road not very far from 
town on the way to the quarry? Have you the color of the anthers? My 
label “near quarry” on this number, but if it did grow by the quarry I 
do not seem to have a specimen of the roadside tree. 

The Flavae species from roadside, West Feliciana. We have fruit col- 
lected by Mrs. Butler but no flowers and the color of the anthers should 
be known. It seems nearest to C. abbita Beadle but the pedicels and 
calyx-tube are more densely pubescent and the leaves of C. abbita do 
not have the very conspicuous clusters of white hairs in the axils of the 
leaves found in the Feliciana plant. I presume that all the plants of this 
group which we saw in West Feliciana are of the same species. This plant 
is especially interesting as the only Flava[e] species which we have found 
in Louisiana, and as the species of this group which grows further west. 
I hope you can get the flowers. Could n’t Mrs. Butler collect and press 
them for you? This plant blooms very early. 

Viridis species. You can add C. velutina Sargent (Trees and Shrubs, 








1965] EWAN, LETTERS FROM SARGENT TO COCKS 337 


ii. 238) to the Louisiana species as I find a specimen of it which I col- 
lected at Shreveport April 20, 1901. This is not surprising for it is 
common at Fulton, Arkansas. 

Viridis species. A tree with dark rough bark in yard of house by road 
below Lake Charles. The stamens and anthers agree with those of C. 
enucleata Sargent, but the leaves have n’t the very conspicuous axillary 
tufts of that species. The flowers are larger. This seems an undescribed 
species. Fruit is needed. You remember what a very handsome plant 
this was. 

On October 8, 1913, we collected a Viridis species in low woods near 
Monroe. This was a large tree and had dark scaly bark, and was growing 
with C. opaca. Bush collected what I take to be the same thing August 
10, 1900, near Minden “on right side of road to prairie west of town, 
just before getting to spring. Bark of trunk rough, dark, scaly and flaky, 
exactly as in C. aestivalis which is beside it.” This seems to me an un- 
described species and we ought to have flowers, color of the anthers, etc. 

There are a number of interesting Crus-galli and Viridis species col- 
lected by Palmer in western Louisiana of which I have n’t yet the color 
of the anthers. With that information I shall probably be able to refer 
some of these to described species. 

I have a number of fragmentary Viridis specimens, including your + X. 
from Natchitoches April 5, 1912. The most interesting of these fragments 
are some sterile branches of a shrub two to three feet high with three- 
lobed leaves at the ends of the branches which I collected at Monroe April 
13, 1901. Did you ever see such a thing? 

I have discarded as hopeless the Viridis species on the roadside east of 
Opelousas as this tree has been cut down, and Richland specimens of 
Viridis species 16 and 23 of 1908 collected by you. 

It is surprising that there are no Mollis species in western Louisiana 
for they are very common in Fulton, Arkansas, and eastern Texas; and I do 
not remember any species from eastern Louisiana but silvicola and 
brachycantha, and the Flava species. There must be others there. 

Don’t you think it would be a good idea to make a serious Crataegus 
drive this year and see if we cannot get this business closed up? So far 
as trees and shrubs are concerned there is n’t anything else very important 
to do in Louisiana with the exception of a more thorough exploration of 
the eastern part of the state where I feel sure you will find species not now 
recognized as belonging to the state. 


169 
March 28, 1918. 
I have yours of the 25th. When we collected the F/avae species in West 
Feliciana, the plants were out of bloom and we did not get the color of 
the anthers. It is possible but hardly probable that there are two Flavae 
in West Feliciana. 
Crataegus opaca of Hooker is the only May Haw of Louisiana and 


338 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Texas and was first collected by Drummond. It is quite a different plant 
from the Carolina species of that name. 

I hope you will be able to finish up Crataegus this year, and there is 
still that Carya alba with slender branches to dispose of. 

You will, I am sure, be sorry to hear that my son who was so often 
my companion in Louisiana died in his sleep last week of what was prob- 
ably some heart trouble. He was perfectly well and in the best of spirits 
when he went to bed in the evening. This occurred at French Lick, In- 
diana. We have been so often together in different and often remote parts 
of the world that the bond between us was a very close one. 


170 
April 5, 1918. 

You collected an interesting Crus-galli Crataegus species at Sardis with 
villose corymbs, yellow anthers and ten stamens, your No. 1008. There 
is no fruiting specimen and only a couple of half-grown loose fruits. 
Perhaps you will be able to get fruiting specimens if you are in Alabama 
this summer. So far as I can see this is undescribed. Harbison does n't 
seem to have collected it, but he collected a Crus-galli species in your 
region with ten stamens and rose-colored anthers. Of this there is no 
fruit either. 

There appear to be a lot of Flavae in that region, but, as I have already 
written to Harbison, there is n’t a single fruiting specimen to go with 
either yours or his flowering specimens. I have asked him to look out 
for this and perhaps you will do the same. 


171 
April 9, 1918. 

Thanks for your last letters. I am sorry to hear that Crataegus is be- 
ginning to misbehave itself this spring. The Crus-galli I should think 
would still be in flower for it is generally very late. 

Is it not No. 1 with the broader leaves which is the tree by the roadside 
at Winnfield and No. 2 the tree of the quarry with a tall very slender stem 
and a small head of small branches? This is the way I have them num- 
bered, but apparently you consider No, 2 the roadside tree. 


172 
May 10, 1918. 

How are you getting on and have you found any new Louisiana trees? 
And are you doing anything about that wretched Ferry Linden at West 
Lake Charles? 

I have a note that Carya cordiformis grows near the coast in western 
Louisiana. This I suppose would mean Lake Charles, but I can find 
no specimen here from western Louisiana except from Natchitoches and 
near Opelousas. Did you ever see it about Lake Charles or anywhere 
near the coast? 

How about the specimen of Carya pallida from near Alexandria?

Dear Professor Cocks: 
How are you getting on and have you found

any Louisiana trees? And are you doing anything about 
that wretched Ferry Linden at West Lake Charles? 

I have a note that Carya cordiformis grows 
near the coast in western louisiana. This I suppose 
would mean Lake Charles, but I can find no specimen here 
from western Louisiana except from Natchitoches and near 
Opelousas, Did you ever see it about Lake Charles or 
anywhere near the coast?

173 
May 22, 1918. 

I am finishing up my long delayed Carya paper and am going over the 
leiodermis-callicoma group. 

No. 5 from east of Opelousas is the type of C. leiodermis and I don’t 
know how to distinguish C. callicoma from it except by the smaller fruit 
and a thin husk and the bright red color of the young leaves, and I am 
not sure that the young leaves of C. leiodermis are not sometimes red. 
Do you know? Both forms seem to grow east of Opelousas and at Lake 
Charles where the red leaf is the most common. C. leiodermis was col- 
lected at Hammond, on the road from Springfield to Pontchatoula, May 
29, 1917, and near Loranger March 30, 1917. This I think is the same. It 
is the tree I thought might be an alba with thin branchlets. 

I think now our Winnfield tree near the quarry which has bothered 
us for so many years is also C. leiodermis. We got it west of Opelousas 
March 26, 1917, and it is I think your Natchitoches No. 2, October 1913, 
and No. 17, September 1914. It grows, too, at Natchez. If you know any 
character by which callicoma can be kept as a species please tell me, other- 
wise I shall call it lecodermis var. callicoma. 

Your No. 5, Natchitoches October 1913, seems to be an arkansana 
which I shall call C. Buckleyi var. arkansana. 

This seems to finish up all the unplaced Carya material from Louisiana. 
Now it is up to you to find something new. 


174 
May 25, 1918. 
Palmer’s Lake Charles No. 7682, Natchitoches 7411 and 7394, Grand 
Ecore 7524 and Chopin 7412 seem to be Carya leiodermis. They may 
belong to the variety but these specimens are without fruit and it is impos- 
sible to say whether they belong to the species or variety. It seems safer to 
put them under the species. 


175 

May 27, 1918. 
Britton in his tree book says that the Nutmeg Hickory is called Bitter 
Walnut in Louisiana. This must be a fake story for in the first place the 
kernel is not bitter, and secondly is so rare in Louisiana that it cannot 
have secured a popular name. Moreover, it was not known to grow in 
Louisiana until after Britton’s book was published, and he does not include 
that state in its range. I do not suppose that you have ever heard it called 

anything but Nutmeg Hickory. 


176 
May 29, 1918. 
I am very glad to get the package of plants. The Ferry Tilia specimens 
are fine. I felt sure that if you stuck to the job long enough you would find 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 341 


Quercus laurifolia in Louisiana and now you have done it. The little 
White Oak is a dwarf form of Quercus stellata Margaretta, and if it spreads 
by underground stems I do not see why it is not the variety stolonifera 
which grows at Selma. 

We cannot see here anything in your Leucothoé but axillaris which 
varies greatly in the width of the leaves. I do not think there is anything 
in Small’s species especially as broad and narrow leaves appear to occur 
and sometimes on the same plant. I hope you will find more things in 
eastern Louisiana. 


177 

June 4, 1918. 

I send you a copy of my Quercus paper. Your Live Oak should be, of 
course, Quercus eximia and not Q. eximea. 


178 
June 11, 1918. 
We have nuts but no leaf specimen of your Carya /aciniosa from Berlin 
[Alabama]. Can’t you dry one for us if the tree is still alive? 


179 
June 19, 1918. 

Your Carya 4030 near Kentwood, Tangipahoa, is probably a leiodermis, 
but 4028 is C. pallida and the only intimation we have here that it is a 
Louisiana tree. I wish I could see your specimens from Alexandria. 

I believe that you will find both Carya Pecan and C. texana in West 
Feliciana as these two trees occur at Natchez. They are certainly worth 
looking for. 

We have no specimen of C. ovata from eastern Louisiana where no 
doubt it occurs. It is rather curious that we have no Alabama specimen 
of C. ovata except from the Selma region. I wonder if, like C. laciniosa, 
it only grows there in the state. 

I have about finished up what I can do with Carya, not a very satis- 
factory piece of work. 


180 

July 12, 1918. 
Your No. 1761, Richlands P[arish], May 1909, called C[arya]| ovata, 
must be a leiodermis: certainly it is not C. ovata. The specimen consists 
only of a sterile branch, There is no other thin-branched Hickory in 
Louisiana but Jeiodermis to which it can be referred. I have finished my 
Carya paper and sent it to the printer, and now I must make my annual 

onslaught on Tilia which is by far the most difficult of all the groups. 
I believe you haven’t collected in Louisiana any Azalea but A. nudi flora. 
There is an Azalea in the swamps at Biloxi which seems to be a new 


342 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


species, and Azaleas other than nudiflora are common in southern Arkansas 
and eastern Texas. Isn’t this the genus that needs your attention? 
I hope your crops are prospering. 


181 
July 16, 1918. 
If everything, as you claim, grows in Selma and its neighborhood how 
does it happen that you have not found there a Philadelphus? Two 
species are credited to the state, although there is nothing in this herbarium 
to show that they really grow in Alabama. It might be worth while to look 
about for one of these plants in your region. 


182 
July 22, 1918. 

The package of specimens has arrived. If you say that these Tilia 
specimens came from our tree by [the| ferry I suppose I shall have to 
believe you, but I have never seen Tilia behave in such a disgusting way 
before. I do not know what to think of it. 

I am glad you sent the Hickory specimen for it is not Carya laciniosa 
at all but C. tomentosa variety subcoriacea. It is surprising that it should 
grow, however, in low ground. What sort of bark have these trees got? 
Please let me know about this as my paper on Carya is already in the 
hands of the printer. Your /aciniosa from West Feliciana Parish seems 
to be all right. 


183 
July 29, 1918. 

I have your note about Philadelphus and Azalea. I find your specimen 
of Philadelphus which has been placed under P. inodorus. This species and 
grandiflorus are very closely related. 

The Azalea which you say you sent from Pearl River eight years ago 
we are unable to find. I should like another specimen sometime if you have 
one to spare. I suspect that it may be the new species from Biloxi. Is 
there no summer-flowering Azalea about Selma, or any Azalea except 
nudiflora? Harbison is finding several new species and I should not be 
surprised to find that some of them are in your neighborhood. 


184 
August 12, 1918. 
I am much obliged for the Alabama specimen of Carya laciniosa. 
Judging by the color of the branchlets and the fruit there can be no doubt 
about the correctness of the determination, but the leaves are remarkably 
glabrous on the lower surface for this species 
I have at last finished my paper on Tilia; so please do not find any more 
new species about Selma. I think Louisiana, at least, is exhausted. 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 343 


185 
August 17, 1918. 
Will not this autumn be a good time to collect Crataegus for the fruit 
in the hope of completing the specimens next spring with the flowers? 
Do not forget that Quercus Cocksii needs a good deal more investigation. 
The Azalea in swamps at Biloxi is certainly a new species which grows 
also in the central peninsula of Florida and in southern Georgia where it is 
sometimes twenty feet high. It blooms apparently sometimes as late as 
August Ist. Why should not this be found in some of the swamps near 
Selma? I should guess that it was the Azalea you found once near Pearl] 
River in Louisiana, although I do not think that Azalea viscosa gets into 
the south at all. It would be interesting to find this Aza/ea in both Alabama 
and Louisiana. I am sure, too, there are other undiscovered plants in 
eastern Louisiana. 
I do not believe it has been as hot in Alabama as it has been here 
during the past week. 


186 
November 6, 1918. 

I have yours of November Ist. I am very sorry to hear about your 
accident. That is a bad road between Opelousas and the western woods at 
the best and I fancy that mules are the safest method of transport over it. 
I am not surprised that you are knocked out. 

I am glad to hear that Carya cordiformis grows near Selma but how was 
I expected to know if you did not send me a specimen? Isn’t [what you 
have labeled] C. megacarpa stelipila [in reality C.| leiodermis? 1 hardly 
believe that Gordonia reaches Louisiana. Mohr found it at only one station 
in Alabama. Gray apparently guessed that it grew in Mississippi, at least 
there is no specimen in his herbarium to show that it grew there, and 
Robinson lays the blame to Gray. As for Small’s statement that it grows 
in Louisiana, you know how much that is worth. 

My Tilia paper is so long that it will be published in two parts in the 
November and December issues of The Botanical Gazette. Do not be dis- 
couraged about Crataegus. We shall certainly be able to get material we 
want next year. 


187 

November 27, 1918. 
I am glad to get your letter of November 18th and the package of plants. 
“Azalea viscosa” is certainly the same as the species at Biloxi, Missis- 
sippi, which is common in southern Georgia and in the central Florida 
peninsula. This is evidently a new species which seems to bloom at mid- 
summer in Georgia and Florida and sometimes gets to be twenty feet high. 
We are slowly getting together here material for a paper on American 

Azaleas.18 


* Witson, E. H. & A. Renper, A monograph of azaleas. Publ. Arnold Arb. 9. 1921. 


344 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


Your Vaccinium seems to be tenellum, but Palmer’s tenellum, Morning- 
port 9811 and Natchitoches 9429, called by him tenellum, are probably 
V. Elliottii which you seem to have collected at various places in Louisiana. 

I hope you are getting ready for a successful Crataegus campaign in 
1919. 


188 
December 6, 1918. 

The tree which we used to think might be Tilia glabra in Louisiana and 
Alabama I have referred to T. nuda in spite of the tufts of hairs in the axils 
of the veins (see page 427 of my paper). This may not be a proper solution 
of the difficulty but I do not know how to make it otherwise. 

I hope you may be able to distinguish the different species of Tilia when 
you see them in the woods. I certainly never expect to be able to do it. 
I am not very well satisfied with the outcome of this investigation, but the 
species show no really good botanical characters. 

I have placed your Quercus 938 of Alabama with Trelease’s subintegra. 
I said nothing about it in my paper for I made no mention of hybrids 
made by Trelease. His paper contains names only without descriptions or 
any references to his types. 

I do not see much prospect of the appearance of the new edition of the 
Manual at present. It has taken the best part of the year to prepare the 
Oak, Hickory and Linden papers, and there are several other genera to 
work over. Now I am working on Celtis which is difficult, but fortunately 
there are not many species. It will take a year, I suppose, to print the book 
when it is ready. 

Wodehouse it shall be. If a fellow insists on having such a lot of names 
I do not see how he could expect to get them all spelled correctly. I suspect 
the neighborhood of Opelousas is still the best part of the state for 
Crataegus. As you know, we never did anything in that region east of the 
railroad and south of the town that Harbison talks about. As far as I 
have seen there does not seem to be many species east of the river. 


189 

December 14, 1918. 
In the Kew Herbarium there is a specimen collected by Drummond at 
New Orleans which proves to be Salix longipes variety venulosa. We 
can find no other indication, however, that this species grows in the state. 
Judging by Drummond’s blue-fruited Crataegus, he labeled plants “New 
Orleans” which he collected across the lake. I enclose a few leaves and a 
flower-spike from a Texas specimen to show you what sort of a looking 
thing Salix longipes is. The species is common in Florida and in western 
Texas but we have no specimens from eastern Texas or Alabama. The 

Louisiana station for it seems worth looking up. 
You will have to change the name of Celtis mississippiensis Bosc to 
C. laevigata Willdenow for it seems that Bosc never gave the Celtis which 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 345 


he said came from the mouth of the Mississippi River a name and 
Willdenow’s name is much earlier than the first published C. mississip- 
piensis. It is astonishing how mistakes in botany are perpetuated from one 
generation to another. 


190 

December 16, 1918. 
There is no Celtis in the herbarium from eastern Louisiana where I 
suppose it is common, and from western Louisiana only specimens col- 
lected by Palmer and one by Mohr near Alexandria. Apparently we have 
never paid any attention to Celtis and we ought to have more material here. 
Celtis laevigata must be common in Eastern Louisiana, and possibly 

georgiana which apparently grows in the Selma region. 


191 

December 18, 1918. 
You appear to have got a new Alabama tree in Celtis occidentalis var. 
crassifolia, Sardis, 1913, no number. This is a tree with leaves very rough 
above and pilose below on the midribs and veins, and with pubescent 
petioles and peduncles. The leaves of your specimen are exceptionally 
entire for this variety but I do not think it can be anything else. Do you 

know anything about this tree and is it abundant? 


192 
December 30, 1918. 

I found the other day in the Gray Herbarium a specimen of Celtis 
laevigata (mississippiensis) collected by Hale in Louisiana without date or 
locality, also a specimen of the same tree collected by Carleton R. Ball in 
the vicinity of Alexandria May 25, 1899 (No. 453). 

Now it seems there are no Louisiana specimens of Platanus in the 
herbarium. Have you ever paid any attention to this tree? There is 
quite an interesting form which grows in Texas and also near Selma where 
it was collected by Harbison with leaves distinctly cuneate at the base. 
This form is without a name. I should think it must occur in Louisiana. 
I wish you would look at your specimens and see if the leaves of any of 
them are cuneate at the base. This is a genus of which I hope you will 
collect specimens for the Arboretum next year. 

With all good wishes for the New Year, I am, 


193 
January 6, 1919. 
A new tree for Louisiana is Acer Negundo var. texanum Pax. This is 
Palmer’s No. 7546 from Chopin and No. 7597 from Alexandria. Your 
Specimen collected in April 1901 in swamps at New Orleans, no number, 
is also var. texanum. This is the only specimen we have here from eastern 
Louisiana where I suppose it must be a common tree. It would be well 


346 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


to collect it there. We have no specimen of Negundo of any sort from the 
Selma region, or indeed from any part of Alabama. If everything else grows 
at Selma I suppose the NVegundo must be there. 


194 
January 14, 1919. 

I am sorry to hear of your continuous hard luck as a planter and I 
shall be very sorry if you have to abandon your Berlin plantation for the 
neighborhood of Sardis is one of the best places in the United States for 
trees and I do not believe that field is exhausted yet. 

We have here no specimen of typical Celtis occidentalis from Louisiana 
or Alabama, no crassifolia from Louisiana, and only the abnormal one 
with nearly entire leaves from Sardis about which I wrote you before. 
If crassifolia grows in Louisiana I should know about it at once. Celtis 
georgiana, which is common in the Selma region, I think will be found in 
eastern Louisiana. 

Sugar Maple. The southern form of Acer saccharum differs from the com- 
mon northern form in the glaucous (not green) lower surface of the leaves 
which are usually slightly pubescent along the under side of the midribs 
and veins. This is var. glaucum (Pax) Sargent. Your No. 2520 from 
Saint Francisville, May 15, 1915, I feel satisfied is this tree which we 
collected also with young leaves at Woodville, Mississippi. The Saint 
Francisville specimen is the only one I have seen in Louisiana. It seems 
more common in the Selma region where Harbison collected it several 
times. Your Sardis 825, July 2, 1915, is this tree. It is common in south- 
ern Arkansas but no one seems to have found it in western Louisiana 
where A. floridanum is common. The last can be distinguished by the 
pubescence which covers the whole lower surface of the leaves and by 
the much smaller fruit. I commend Acer saccharum to your prayerful 
consideration. If you can understand American Lindens I congratulate 
you for I certainly cannot. 


195 

January 16, 1919. 

I have been studying the Red Maple and am not able to separate the 
variety Drummondii as a species for I find specimens with trilobed leaves 
rounded at the base which appear to connect it with A. rubrum var. tridens. 
For this form I am going to propose the name of Acer rubrum var. Drum- 
mondii {. rotundata, making the type Palmer’s No. 7553 from Chopin. 
You got nearly the same form at Glen Gordon, Covington, May 28, 1911. 
It grows also at Poplar Bluff, Missouri. Unfortunately I have not seen 
the fruit of this form. Would it be possible to get it from the Covington 
tree this spring? This is the only Drummondii specimen we have from 
eastern Louisiana. We collected it on our trip to Natchez, near Wood- 
ville, Mississippi, so I suppose it grows in West Feliciana. Have you col- 
lected it there? This is a Louisiana tree which needs further study, eS- 
pecially in the autumn. Autumn specimens are needed to show the amount

and character of the tomentum on the leaves, petioles and branchlets at 
that season. Won’t you look out for it then and try to establish its range 


fruit, glabrous branchlets, glabrous petioles and less tomentose leaves. 
Moore got this at Mt. Vernon but I do not find it among the Selma-Sardis 
specimens, or indeed a specimen of any sort of a Red Maple from there 
— why? 

Of what may be considered the typical Red Maple from Louisiana we 
have Palmer’s Natchitoches No. 7571 and perhaps No. 7041, with fruit 
only. Low woods, Winnfield, Cocks and Sargent, April 6, 1913, and noth- 
ing from East Louisiana where it should be looked for. Of the variety 
tridens one Louisiana specimen from West Lake Charles, Cocks and Sar- 
gent, April 13, 1915; Fairfax Road, Shreveport, Cocks, April 1, 1910; 
Butler Plantation, Cocks and Sargent, April 14, 1916; near Hammond, 
Cocks and Sargent, March 30, 1917; Lucknow, Richland Parish, Cocks 
and Sargent, March 1910; Winnfield, Cocks and Sargent, October 9, 1913. 

The important trees to collect from are the common widely distributed 
species which show the greatest tendency to variation. These varieties are 
interesting and have been too much neglected. You are better placed 
for studying Acer Drummondii than any one and I venture to hope that 
you will pay attention to it and to other forms of the Red Maple.

January 20, 1919, 

Magnolia glauca will have to be called M. virginiana I am sorry to say, 
and I am distinguishing the southern form with pedicels and branchlets 
thickly covered with silky white pubescence as variety australis, This is 
usually a large tree and is the only form in Alabama, Mississippi, Louisiana 
and Texas. I judge by the material here that this is a comparatively 
rare tree in Louisiana, for in this herbarium there are only the specimens 
we collected at Winnfield October 9, 1913, and Palmer’s Natchitoches 
specimens numbered 7573 and 7931. These two specimens are remark- 
able in their broad oval leaves. Unfortunately there are no flowers. I 
should have supposed that Lake Charles would have been just the place 
for this tree. 

Please notice that we have no specimens from eastern Louisiana and 
please tell what you know of the distribution of this Magnolia in Louisiana. 
More Louisiana material would be acceptable. 

The flowers of our West Feliciana Magnolia acuminata are so large that 
I want to distinguish it as variety /udoviciana. I call the type the tree on 
the Dessert Plantation.1® Is this name right and is this Plantation in 
Laurel Hill, and, if not, where is it? We got it also at the West Plantation. 


** Near Bayou Sara, West Feliciana Parish. 


348 JOURNAL OF THE ARNOLD ARBORETUM [ VoL. 46 


Is this also in Laurel Hill? I suppose your Catalpa and St. Francisville 
specimens are the same but there are no flowers and the leaves are more 
typical of the species. 

You ought if possible to make a thorough exploration of Louisiana and 
gather specimens of every tree, even the most common, for it is impossible 
to tell what may turn up. Can’t you manage this? 


197 
January 27, 1919. 

I have yours of January 19th. In regard to Acer floridanum we have 
your two Natchitoches specimens collected in 1902 and 1905, and Palmer’s 
Natchitoches No. 7400; also A. floridanum collected by us at the Dessert 
Plantation April 12, 1916. 

I am sure Elwes will enjoy the Louisiana trees. I think, however, that 
he will fully occupy your time while he is there and that you will have all 
you can do and listen to without being bothered with me at the same 
time. If I ever get to Louisiana again I shall hardly select Elwes for a 
companion. I hope you are going to be able to get all over the state this 
year and finish up the trees and shrubs. 


198 

January 28, 1919. 
I am glad to hear from yours of the 24th that Magnolia glauca is so 
common in Louisiana. The fact that we did not know this here only 
shows how poor this herbarium still is in Louisiana specimens. Does it 
ever grow in Louisiana as a shrub? Please notice if the petiole of the 
flower is ever glabrous as in the northern form of this tree. On specimens 
from west of Florida which I have seen all the pedicels are covered with 

white silky hairs. 


199 
January 31, 1919. 

I am much obliged for the package of specimens which arrived this 
morning. The two Magnolia glauca specimens have the silky pubescent 
pedicels and are my M. virginiana var. australis. I fancy that every 
Louisiana specimen will be of this variety. 

No. 658, Celtis occidentalis from Sardis is C. laevigata (mississippien- 
Sis). 

No. 748, Acer Drummondii = Acer rubrum var. Drummondii forma 
rotundata Sarg.. showing a connection of Acer Drummondii with Acer 
tridens. 

No. 2818, Acer Drummondii, is intermediate between A. rubrum vat. 
Drummondii and the forma rotundata. 

I am getting a good deal interested in Acer Drummondii and wish | 
knew more of its distribution. I now believe that it does not get east of 
Mississippi and that all the forms from Alabama, Florida, Georgia, etc., 


~~ 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 349 


which have been referred to it are Acer rubrum tomentosum. There is a 
lot of talk about this in my next Botanical Gazette paper which is booked 
for the March number. 


200 
February 4, 1919. 

Palmer’s Celtis from Cameron Parish is No. 3533, not No. 8534 as you 
say. I do not think it can be anything but a rather small-leaved form of 
Celtis mississippiensis which varies greatly in the size of the leaves and 
in their broader but narrower bases. We have n’t in this herbarium a 
single Celtis specimen collected by you or by you and I. Louisiana certainly 
ought to be better represented here. 

Elwes is all right. He is a gentleman and has already been pretty much 
all over the world. The only trouble is that he talks too much and too 
loudly and positively, and so much that he has gone around the world 
without really seeing anything. It is perfectly all right to take him to 
Butler’s or anywhere else. My only idea was that if I wanted to have 
a quiet and restful time in Louisiana I should not select him for a member 
of the party. 


201 

February 6, 1919. 
Your Acer rubrum No. 869, New Orleans, is a puzzle. It is not rubrum 
and looks more like nigrum than anything else. If it is nigrum and not 
a cultivated tree it is a very long way from where it belongs. Do you 
remember this tree and is it still in existence? This seems to me a matter 
worth investigating. As the label says New Orleans I think it may have 

been planted there. 


202 
March 1, 1919. 
It is some time since I heard from you. Was that Acer nigrum from 
Louisiana too much for you? Small, I see, credits Castanea nana to 
Louisiana. We certainly have no evidence that it grows in the state and 
there are no specimens here from Mississippi or Alabama. I am getting 
interested in this plant for Harbison has found a Chinquapin on St. 
Andrew’s Bay in western Florida forty feet high which, although I have 
not seen the fruit, I take to be a glabrous form of C. mana for which, by 
the way, C. alnifolia Nuttall is the correct name. It would be well there- 
fore, if you see any strange looking Chinquapins in your travels, to make 
specimens. All the forms of alnifolia are easily distinguished by the 
glabrous or nearly glabrous branchlets and much narrower leaves; and 
by the prickles on the fruit being in distinctly separated clusters. 
lwes seems to be weakening on his trip to America this spring as he 
has difficulty in getting transportation. He was not, however, quite 
decided when he wrote last. 
What is the Crataegus situation?

March 10, 1919. 

I have this morning your letter of March 6th. I had no idea Ames was 
in New Orleans. A letter addressed to him at the Ames Building, Boston, 
will reach him. 

I am glad to hear it is a late season with you for this means that there 
will be a better chance for Crataegus. 

As I wrote you, the last time I heard from Elwes he was thinking of 
giving up his trip. 

I am planning to impose on your good nature by giving a letter of 
introduction to you to Professor Blareningham of the Pasteur Institute 
and the University of Paris. He is here this winter as an exchange Pro- 
fessor at Harvard and is planning a journey south and west which will 
take him to New Orleans for a day or two sometime before the end of 
this month. If you could arrange for him to make a trip across Lake 
Pontchartrain, perhaps that would be the best thing he could do in the 
short time he will have in New Orleans. He is particularly interested in 
trees for he has been put in charge of the Arboretum at Angiers which has 
lately come into the control of the Pasteur Institute. His wife speaks 
English quite well. 


204 
March 18, 1919. 

Have you ever looked for Myrica inodora on the Louisiana side of Pearl 
River? It grows at Poplarville, Mississippi, and might get further west. 
Pearl River swamps in Washington Parish would be the place to look 
for it. 

How does it happen that there is no Myrica about Selma as we have no 
specimen from there? 

I had another letter from Elwes telling me that with his nephew, a naval 
officer, he is sailing on the 25th of March for New York. He proposes to 
go south before coming here. Whatever equipment you may need for 
your journey with him you certainly will not require an ear trumpet. 


205 
March 20, 1919. 
When you go to West Feliciana with Elwes please pay attention to that 
species of the Flavae Group of Crataegus about which we do not yet 
know enough. You remember, of course, that station of Harbison’s just 
off the railroad below Opelousas which we have never visited. 


206 


March 22, 1919. 
I have yours of March 20th about a Garden Society and I will see if 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 351 


I cannot find some material in our nursery to send you the first of the 
week. 
They call Crataegus beastly, but there is really a lot of fun in them? 


207 
March 26, 1919. 
All the plants which I can find in our nursery at all suitable for Louisi- 
ana are mentioned on the enclosed, and go by parcel post. It is a very 
poor and unsatisfactory list but by another year or two the seedlings of 
the Formosa trees, all of which I hope will do well in Louisiana, ought 
to be big enough to send you. 


208 
April 5, 1919. 

We have no specimen of Chrysobalanus oblongifolius from Louisiana 
and I shall be very glad of your specimen from Bogalusa. 

I had a letter from Blareningham written in New Orleans. Instead of 
staying one day in Miami, Florida, as he intended, he staid three. This 
cut down his Louisiana visit and apparently he only staid a few hours in 
New Orleans. He said he did not have time to look you up but would 
write to you explaining why he had not called. This I suppose he will 
do in time. 

I have n’t heard yet that Elwes has arrived but I suppose he may get in 
now any day. I have advised him to go to New Orleans via Jacksonville, 
Florida, and to stop off at River Junction, Florida. If he does this it 
may take him some days to recuperate. 

I hope you have had a successful time with Crataegus, and I regret 
extremely that I was not with you. I am really pining for another visit 
to that hotel in Opelousas. 


209 
May 29, 1919. 
Many thanks for the package of Crataegus which I have looked over.

No. 3175, Zlex lucida. 

Nos. 3168, 3145, Ilex. These I should think represented the same 
species ; untese this is lex monticola I don’t know it. It is desirable to 
get mature leaves and fruit. The shape of the leaves agrees pretty well 
with specimens here of /lex monticola from North Carolina but their ser- 
ration is rather different. I hope you have not found a new arborescent 
Ilex.

No. 3172, Leucothoé racemosa. You have also collected this at Cov- 
ington. 

No. 3131, Gavylussacia hirtella. We have this from Ocean Springs, 
Mississippi. 

No. 3163, Pieris nitida. We collected this at Hammond 

Your shrubby Myrica from Bogalusa is not like anything I have seen. 
This needs further investigation. Judging from the material in this her- 
barium, I should think it was an undescribed species. I am glad that it 
is only a shrub as Myrica for the new Manual will be in type in a few 
days. 

Judging by the Crataegus specimens, I should not think you had been 
in that particular field along the railroad south of Opelousas that Harbi- 
son has always been talking about. 

I hope to hear that you are coming north this summer. Won't it be 
necessary pretty soon to come here to elaborate your Catalogue of Louisi- 
ana plants: 


210 
June 27, 1919. 

In this herbarium there is one specimen only of Castanea. This was 
collected by you at Covington March 28th, 1911, leaves only. It appears 
to be my C. alnifolia var. floridana. 

Castanea pumila must be common in Louisiana as it grows at Natchez, 
Biloxi, Fulton on the Red River, and at many places in eastern Texas. 
How have we and Palmer missed it? Please tell me what you know about 
this tree in Louisiana. 

Elwes was here four very hot days and then went to Rochester, New 
York, and to New York City. He sailed for home ten days ago and I 
suppose is now safely there. He appears to have had a very good time 
and to have seen much to interest him. He did not, however, seem to be 
much impressed with the Live Oaks, and said the largest he saw were on 
Avery Island where I did not see anything very large in the way of trees. 

Any chance of your coming north this summer? 


211 
July 14, 1919. 
I take much pleasure in having your name placed on the mailing list 
of the Journal of the Arnold Arboretum for a complimentary copy. 
You will, I hope, receive the first number in the course of a few days.

I have your last package of plants. 

1915 may be a new variety of Celtis pumila, or perhaps a new species. 
The shape and serration of the leaves are like those of C. occidentalis but 
the pedicels are much too short.

1917, Celtis pumila. 

1918, Vaccinium atrococcus. 

1919, Fraxinus americana? It is too pubescent and the leaves are not 
of the normal shape. Fruit of this should be collected.

1921, Fraxinus americana. 

1922, Carya cordiformis.

The Selma region seems to be maintaining its reputation for strange 
trees. I am sorry to hear that you won’t be here this summer.

We have Ulmus fulva only from western Louisiana. Does it not occur 
east of the river? 
An early answer will oblige.

August 29? [1919] 
I thank you for your note. The right sort of things certainly have not 
been coming my way of late for in the last eighteen months five members 
of my immediate family have gone! 
Fortunately I have three devoted daughters & a great deal of work to do.

September 2, 1919. 

I have to take up Prunus for my new Manual now almost at once and 
have only unsatisfactory material and imperfect knowledge to work with. 

You collected March 22d, 1911, at Natchitoches Prunus 6 and 7. Have 
you followed these up? I suspect they may be the so-called Big Tree 
Plum, P. arkansana or P. mexicana S. Watson. Palmer also collected a 
number of specimens at Natchitoches but no mature leaves or fruit. These 
are needed from western Louisiana. We have from you also sterile branches 
of the Prunus collected at Ruston, Louisiana, Nos. 4 and 9, August 4 and 
September 22, 1914, but these are only sterile branches. 

You have seen, I believe, about Sardis Prunus umbellata with yellow 
fruit. I cannot make up my mind whether the red-fruited tree in Alabama 
and Florida which looks like umbellata should be considered a variety of 
that species or something distinct. Have you any opinion on this? 


354 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


There is still for you to look up this autumn Castanea alnifolia, C. 
floridana from across the lake, Quercus Cocksii, your new Myrica from

logue ready for publication? I want to live long enough to see it.* 


216 
September 4, 1919. 
I am sending you under another cover a few seeds of a Mulberry and 
an Elm from the Himalayas. These trees ought to succeed in New Orleans

October 31, 1919. 
We are sending you by parcel post two plants of Pinus luchuensis, eight 
of Paulownia Mikado and six of Quercus pachyloma. They were raised 
from seed collected by Wilson in Formosa and these trees ought to flourish 
in New Orleans. Will you find some one who will take good care of them? 
The Paulownia is described by Wilson as a magnificent flowering tree. 
It is some time since I have heard from you, so I suppose you have 
been in the field. I hope that you raised a good crop of cotton in Alabama

November 5, 1919. 

We suspect here now that Hamamelis virginiana does not grow in 
Louisiana and that all the specimens which we have from the state should 
be referred to Hamamelis vernalis which is a winter and early spring 
bloomer, and differs from the northern plant which flowers in October or 
early November by the abundance of the stellate pubescence on the lower 
surface of the leaves. Hamamelis vernalis as I have seen it in Missouri 
suckers freely, spreading into large clumps, while H. virginiana does not 
sucker. The Louisiana specimens which seem to belong to H. vernalis 


are, — 

Richland Parish, Cocks, April 18, 1910, “reported to bloom February 
and March”; Ruston, Cocks, July 1909, with a flowering branch collected 
February 4, 1911; Lake Charles, Cocks, March 27, 1911, Sargent, March 
20, 1911; low woods, Winnfield, Sargent, April 6, 1913, October 9, 1913;

Texas and southern Mississippi specimens seem to belong to Hamamelis 
vernalis. The specimens from Louisiana in flower are very fragmentary 
and unsatisfactory, and I am writing you this now in the hope that you 
will follow up the Hamamelis business this autumn and winter and find 
out just when the Louisiana plants flower. I remember the large treelike 
plant west of Opelousas and if it is H. vernalis I am afraid this species 
will have to find a place in the Manual. Am I right in thinking there are 
large treelike specimens in eastern Louisiana? 

I wish you would look out for large treelike specimens and give me 
their dimensions, also please notice if the suckering habit is common in 
Louisiana. 

I suppose some sort of a Hamamelis grows at Sardis but there is no 
specimen here, and only one Alabama specimen collected by Harbison on 
Sand Mountain. I am afraid there is still much to learn about trees north 
and south. 


219 
4 November 15, 1919. 
Glad to get your letter about Hamamelis. I am surprised that the 
Alabama and Louisiana trees are so large. Can’t you spare me a speci- 
men from Alabama: It is certainly curious that this winter-blooming 
species has been so long mistaken for Hamamelis virginica [sic]. I hope 
you can send us more and better Louisiana flowering material than we 
have now. 
I will see what can be done about Rosa Hugonis. I think we can get 
them for you. 


220 
November 21, 1919. 

The package of plants has arrived safely — many thanks. I am very 
glad to get the Castanea from Sardis. It is what I have called Castanea 
alnifolia var. floridana. 

Your Myrica I do not know at all. As far as I can see now it looks like 
a new species. The black-fruited Vaccinium is, as you suggest, melano- 
carpum. 

I am sorry you did not include a specimen of Hamamelis from Sardis. 
I am anxious to see this. Can’t you help me? 


221 

November 25, 1919. 
hope you are going to be able to send me a specimen of Hamamelis 
from the Selma region. Possibly Hamamelis virginiana gets into northern 
Alabama but I do not feel at all sure of it, and I doubt if it is anywhere 

else in the Gulf States. 
Mohr talks about Hamamelis being common all over the state of Ala- 
bama but we have only one specimen without flowers or fruit from the 


356 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


state. Hamamelis has to go to the printer now almost at once, so I shall 
be glad of any help you can give me. 


222 

December 3, 1919. 
The Alabama Hamamelis has arrived this morning and is the same as 
the Louisiana plant. I am taking up for it Pursh’s name of Hamamelis 
macrophylla for it seems sufficiently distinct in its short stellate pubescence 
and the roughness of the leaves caused by the persistence of the bases of 
this pubescence. It is the only species in the Gulf States where it is 
apparently common and generally distributed, although it does not get 
far south apparently in Florida. I understand that the inner surface of 
the calyx is yellow in this species, like that of H. virginiana, and not red 

as in H. vernalis. Can you confirm this idea? 


223 
December 13, 1919. 
By all means send me a few of your specimens of the Alabama Witch 
Hazel for we have very poor flowering material. I am glad to have the 
information about the color of the inner surface of the calyx-lobes.

Crataegus edita, Cocks, Natchitoches, April 24, 1912, No. xvii.; Palmer 
Natchitoches, Nos. 7288, 8898, 

Crataegus Bushii Sarg., our cn -galli tree in the yard on road to 
English Bayou from Lake Charles; Palmer, Chopin, No. 7234 and No. 
8843, Lake Charles No. 7696. 

You remember the large tree of the Viridis Group in yard down the 
road from Lake Charles with twenty rose-colored anthers and dark bark. 
You have n’t got the fruit of this and there is no other Louisiana speci- 
men here like it. Except in some minor characters it is a good deal like 
C. penita Beadle from Chattanooga. It is also a good deal like C. [blank ] 
Sarg. from Fulton, Arkansas, but it does n’t have the very conspicuous 
tufts of hairs in the axils of the leaves of that species. On a single indi- 
vidual and without fruit I don’t know if it is wise to say much about the 
Lake Charles tree which as we saw it is certainly handsome and interesting. 

With the compliments of the season and all good wishes for the New 
Year, I am

December 26, 1919. 
Thanks for your package of specimens. The Castanea from Baton 
Rouge is pumila. The Selma Hamamelis is interesting and I suppose is 
macrophylla, but the pubescence is different and pubescent through the 
season on the old leaves, so that the tubercles which are usually so promi- 
nent on the Louisiana specimens do not appear. I should be very glad to 
see spring or summer leaves of the Selma plant. Can you manage these? 
I am particularly glad to get your Opelousas specimen of Amelanchier 
canadensis which apparently is a rare plant in western Louisiana, although 
common enough east of the river. Palmer never seems to have collected 
it, and you and I never collected it together. I have only one other western 
Louisiana specimen which was also collected by you. I should have 
supposed that Lake Charles would have been just the place for Amelan- 
chier. We have no evidence that it gets to any part of southern Arkansas 
or that it reaches Texas. Have you ever found it further west than Opel-

December 27, 1919. 

I have this morning yours of the 22d. I have heard the name of Leavitt, 
a supposed landscape gardener, but I know nothing of his ability. Judg- 
ing by others in his class, you may be expected to hear from him how 
to make in New Orleans a Long Island Italian garden. 

As soon as I got your letter I wrote to some people in Pennsylvania 
who propagate Rosa Hugonis and asked them to send half a dozen plants 
to you, and I have written again today to find out why they have n’t done 
it. When I hear from them on the subject I will communicate with you 
again. 

I have got to Crataegus in the Manual! 


Pat | 
us January 2, 1920. 

Conrad [i-e. Conard] & Jones, nurserymen in West Grove, Pennsyl- 
vania, tell me that some time ago they sent you two plants of Rosa 
Hugonis and later four others. Please let me know if these arrived and 
if they were in good condition. 

The best I can do with that Crataegus of the Flava Group from West 
Feliciana Parish is to call it Crataegus constans Beadle. I should not 
like to swear that the determination was correct for we have no type of 
C. constans and Beadle’s descriptions are rather vague but the specimens 
agree fairly well with his description and I don’t believe you can do better 
than to adopt this name. 

The Crus-galli species with yellow anthers, your No. 1008 which you say 
is common near Sardis, seems to be Crataegus algens Beadle. No one has 


358 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


o fruit from the Sardis region. Harbison’s 1471 is apparently the 

. The Sardis Crus-galli species with purple anthers from the Sardis 
oe is evidently C. torva. It is Harbison’s No. 1470. No fruit of this 
has been collected and there is no evidence here that you have collected 
it. The narrow-leafed Crus-galli species from near the quarry at Winn- 
field I am calling C. Cocksii, I hope you can bear it. 


228 

January 5, 1920. 
Professor Wiegand, who is an authority on eastern Amelanchiers, saw 
yours from Sardis the other day and thought it was an undescribed species 
which he has found growing from central New York southward to Ala- 
bama. He is working on a revision of his paper on Amelanchiers and no 
doubt will have something to say about these plants in the course of time. 
Crataegus is easy in comparison with Prunus which I am afraid is a 
pretty hopeless proposition. We received from you on August 20, 1918, 
some small light yellow plums. Is this your No. 36, a leaf specimen with 
one fruit on it which, however, looks much larger than that received 
on August 20. No. 36 looks like Hederick’s [= Hedrick’s] angustifolia 
var. varians. If this is a good guess, then I suppose No. 36 is an intro- 
duced or escaped plant. Indeed all the angustifolias must be that as ap- 
parently it does not grow wild anywhere east of the Mississippi River. 
Let me hear anything you have to say about plums at your early con- 

venience. 


229 
January 11, 1920. 
We have no specimen of Crataegus opaca (aestivalis) from eastern 
Louisiana. Have you ever found it there and where? It grows near Mobile 
and at Meridian and at Hattiesburg, oe and, as you know, it is 
very common all over western Louisiana 


230 

February 16, 1920. 
Hooker mentions without description a Pyrus arbutifolia macrophylla 
as collected by Drummond at New Orleans and Covington. Do you know 
any large-leaved Aronia in Louisiana? In this herbarium there is no 
specimen at all of Aronia from eastern Louisiana. I do not know how 
we could have missed it at Covington. If you have Covington specimens 
with large leaves I wish you would let us see one of these at once. Palmer 
collected in St. Augustine County, Texas, a large-leaved, red-fruited 
Aronia which he describes as a tree twenty feet high. The size of the 
leaves would agree with Hooker’s name. The question is, is there a large- 
leaved variety treelike in habit in Covington or in the neighborhood of 

New Orleans. 
Your specimen of Aronia arbutifolia collected at Deridder April 5, 1912,

is typical. We collected the same thing at Winnfield and I collected it at 
Biloxi when I was last there. 

e are having a terrible winter and are so buried in snow that it is 
almost impossible to get about. I hope you are well. 


231 
February 23, 1920. 
I don’t make anything out of Fraxinus Darlingtonii which I fancy is 
nothing but Fraxinus pennsylvanica. Britton described a large number 
of Ash trees, but according to our ideas here none of them have any 
standing. Fraxinus pauciflora Nuttall is the correct name of Fraxinus 
floridana of my Manual. We have here a specimen collected by Fendler 
at New Orleans April 1848 consisting of a single leaf and a cluster of 
fruit about two-thirds grown. The specimen is not satisfactory but I 
think it is F. pauciflora which I hope you will rediscover. Except for this 
specimen I have no indication that this Ash grows anywhere west of 
the Appalachicola River in Florida. 
I hope you will look further for Aronia in the Covington region and 
make us some specimens. I will try and get from Kew photographs of the 
specimens collected by Drummond in Louisiana. 


232 
March 1, 1920. 
We have here no specimen of Crataegus spathulata from eastern 
Louisiana. Have you ever found it there? As it grows near Natchez it 
might be expected in West Feliciana Parish. It does not appear to be 
in southern Mississippi, and it is, as you know, fairly common in the Red 
River Valley in Louisiana. 
An early answer will oblige. 


233 
March 2, 1920. 

We have placed your Alabama Fraxinus No. 946 with pennsylvanica 
var. lanceolata. The distinctly acuminate fruit is unusual, although we 
have the specimens from Mississippi with similar fruit. I do not believe 
there is any doubt, however, about the species. I should think that 
Fraxinus caroliniana might grow in the Selma region but apparently you 
have n’t collected it there. I am glad to hear you are starting out again 
for Crataegus. 

It does n’t look very much like spring in these parts for there are still 
about three feet of snow on the ground and the thermometer on the Ist 
of March was several degrees below zero. We do not remember to have 
had a winter like this before. 


234 
March 6, 1920. 


We have no specimen of Crataegus apiifolia from eastern Louisiana. It 


360 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


must grow there I should think, certainly in West Feliciana as it seems 
to be common about Natchez. Can’t you send us a men? 

We seem much less well provided with eastern Louisiana plants than 
with those from west of the river. 

The worst snow-storm of the year is going on today. 


235 
March 9, 1920. 
I am glad to hear that Crataegus spathulata is common in eastern Loui- 
siana, but how did you expect me to know it if you never sent me a speci- 
men from that part of the state? I certainly do not remember to have 
seen it there myself. We are very short here of eastern Louisiana material 
and I wish we had more of it. 


236 

March 10, 1920. 

From eastern Louisiana our only specimen of Acer floridanum was col- 
lected by us April 12, 1916, at the Dessert Plantation near Bayou Sara 
and called Acer saccharum. Our only other Louisiana specimens are from 
Natchitoches. I hope you will be able this spring to more fully locate 
this tree in Louisiana. It is probably common in some parts of the state. 
Acer saccharum var. glaucum as a Louisiana tree does not seem to be 
very well known. The only Louisiana specimen we have here is your No. 
2520, St. Francisville, May 15, 1915, and doubtfully referred by you to 
A. floridanum. This is another tree which I hope you will follow up this 
spring as there is no reason why it should not be common in Louisiana. 


237 
March 15, 1920. 
The books talk about Halesia tetraptera in Louisiana and Texas. This 
certainly must be a mistake. The only indication we have that this tree 
grows west of the Mississippi River is one specimen collected in Arkansas 
by Palmer. We have no specimen from Florida or Mississippi and only 
one from Alabama and that of course is from Selma, a region in which 
for some unknown reason so many northern plants find conditions suitable 
for them. The common east Gulf States species with four-winged fruit is 
Halesia parviflora which is evidently much more abundant than I had 
supposed and grows into a small tree. This form is also at Selma; it 
grows at Laurel, oir and it would not therefore be very surpris- 
ing if it got into Louisia 
Britton claims that ea Fraxinus Smallii and F. Darlingtoniana | darling- 
tonii| grow in Louisiana. These we take it are only forms of the Red 
Ash, Fraxinus penns ylvanica, and there is no indication here that this tree 
gets into Louisiana at all. Have you ever found it there? It is a tree 
certainly to be looked for, and if you can find it this spring it will be 
quite an assistance to me as I must now take up Fraxinus and Halesia 
for my Manual very soon.

Rehder has gone to New York today to look up some things in the 
herbarium of the New York Botanic Garden and I have asked him to see 
if he can find evidence there of Britton’s species of Fraxinus growing in 
Louisiana. 


238 
March 18, 1920. 

Rehder is back from his trip to New York and reports the only Loui- 
siana specimen of any of Britton’s new Ashes is one called there Fraxinus 
Darlingtonii, a single specimen collected by C. R. Ball at Gretna across 
the River from New Orleans. This is perfectly glabrous and the ordinary 
form of the Green Ash, so I do not think that Fraxinus Darlingtonti need 
bother you except as a synonym. 

Bumelia cassinifolia is based on a single fragmentary specimen collected 
by Bush near Opelousas. This is all the material that there is in New 
York. We have a photograph of the type specimen with a single leaf which 
we should be glad to lend you if you care to see it. I do not believe there 
is anything in it however. They certainly have a talent in New York for 
making trouble.

NOMENCLATURAL NOTES ON DIPSACUS FULLONUM 
AND DIPSACUS SATIVUS! 


I. K. FERGUSON AND GEORGE K. BriIzICKY 


WHILE ONE OF US was preparing an account of the Dipsacaceae for a 
generic flora of the southeastern United States (Ferguson, Jour. Arnold 
Arb. 46: 226-231. 1965), it was found that the name Dipsacus fullonum 
had been and is still being used by a number of authors in different ways 
and that the combination D. sativus has been attributed to several dif- 
ferent authors. It seems desirable to- review these problems, in the hope 
of resolving the confusion surrounding the usage and typification of D. 
fullonum and the authority for the combination D. sativus. 


DIPSACUS FULLONUM 


The name Dipsacus fullonum has been used in at least two ways. Some 
authors have applied the name to the wild teasel, which has erect recep- 
tacular bracts; the cultivated teasel, which has recurved receptacular 
bracts, is then referred to as D. sativus. Among the workers who have 
adopted this treatment are F. A. Scholler (Fl. Barbiensis 47. 1775), C. 
Schkuhr (Bot. Handb. 1: 67. 1791), N. E. Brown (English Botany, ed. 3. 
Supplement. 197, 198. 1892), E. de Halacsy (Consp. Fl. Graec. 1: 757. 
1901), F. N. Williams (Prodr. Fl. Brit. 1: 201. 1903), E. G. Bobrov (FI. 
URSS 24: 21-23. 1957), and, most recently, A. R. Clapham (in Clapham, 
Tutin, & Warburg, Fl. Brit. Isles, ed. 2. 797. 1962). Numerous other 
authors, including, it appears, all American workers, have applied the 
epithet “fullonum” to the cultivated teasel and the name D. sylvestris 
Hudson to the wild plant. 

A number of authors have commented on the different usages of the 


maintaining that Linnaeus intended the epithet ‘‘fulionum” to refer to the 
wild plant. Arthur Cronquist (in Hitchcock, Cronquist, Ownbey, & 
Thompson, Vasc. Pl, Pacif. NW. 4: 480, 481. 1959), although referring 
to the wild teasel as D. fullonum subsp. sylvestris, has observed that D. 
fullonum could be typified by the wild plant. He says, “The weight of 
historical practice, however, has been to accept the more logical, if perhaps 
less legally proper typification of Hudson, who in 1762 considered the two

Pursuing still another course, H. Schinz & A. Thellung (Bull. Herb.

All references under the first element clearly show that Linnaeus under- 
stood them to refer to the wild teasel with erect receptacular bracts, 
while those under the variety 8 indicate that he was referring to the 
cultivated plant with recurved receptacular bracts. The text of the second 
edition of Species Plantarum (1762) is unchanged, but in the appendix to 
that work (1763) Linnaeus formally named the variety D. fullonunt B 
sativus. 

The year before this, Hudson, in his Flora Anglica (49. 1762), segre- 
gated the wild plant, giving it a new name, Dipsacus sylvestris, applying 
D. fullonum to the cultivated teasel and citing Species Plantarum in the 
references under the latter species. 

Most subsequent authors have recognized the wild teasel, with erect 
receptacular bracts, and the cultivated teasel, with recurved bracts, as 
distinct species or subspecies and have interpreted D. fullonum in either 
of two ways: (1) as represented by the specimen in the Linnaean Her- 
barium, which is the wild plant with erect receptacular bracts and which is 
labeled “fullonum” in Linnaeus’ handwriting, or (2) by following Hud-

It may be contended that the epithet “fullonum” circumscribed the 
two entities that Linnaeus recognized in Species Plantarum and that 
Hudson’s treatment effectively typified Dipsacus fullonum. In support of 
this view it may be argued, as Sprague has suggested, that Linnaeus 
intended the epithet “ pean to apply to the cultivated teasel because of 
the origin of the name. However, this argument does not seem to be of 
great importance, for many Linnaean names are inappropriate. On the 
other hand, Linnaeus himself appears to suggest in Critica Botanica (A.

In Species Plantarum (1: 97. 1753), Linnaeus described Dipsacus ful-

great importance, for many Linnaean names are inappropriate. On the 
other hand, Linnaeus himself appears to suggest in Critica Botanica (A. 


364 JOURNAL OF THE ARNOLD ARBORETUM [ VoL. 46 


Hort, The “Critica Botanica” of Linnaeus, English translation, 203. 1938), 
and Stearn in his introduction to the Ray Society facsimile of Species 
Plantarum (90, 93. 1957) has stated, that where a variety has been 
described within a species the typical element refers to the wild form, 
“the natural species,” “natural form,” ‘natural plant,” or “normal form” 
of Linnaeus. This appears to be the usage that Linnaeus adopted in 
Hortus Cliffortianus (29, 30. 1737), where the first species described, 
Dipsacus capitulis florum conicis, consists of a typical element and three 
varieties (a, 8, y). The phrase name and synonymy of the typical ele- 
ment correspond to those of D. fullonum in Species Plantarum, and the 
phrase name and synonymy of var. y correspond to var. B of Species 
Plantarum. At the end of the description is the observation, ‘Planta 
naturalis gaudet paleis calycinis, flosculos distinguentibus, fere erectis & 
mollibus; varietas autem (8) paleis parum reflexis & rigidiusculis; haec 
autem (y) paleis apice reflexis, duris & hamatis; ista autem (a) foliis 
caulinis incisis a naturali differt planta.” 

It appears to be in agreement with Linnaeus’ concept of species to 
regard the wild plant as the typical element of Dipsacus fullonum. This 
treatment also appears to be consistent with the International Code of 
Botanical Nomenclature (65. 1961): “In choosing a lectotype, any indi- 
cation of intent by the author of a name should be given preference unless 
such indication is contrary to the protologue” and “If it can be shown 
that the element best fitting the protologue has been removed, it should 
be restored and treated as the lectotype.” We are thus in agreement 
with those who apply the name Dipsacus fullonum to the wild teasel with 
erect receptacular bracts. In this circumstance Linnaeus’ specimen of the 
wild teasel with erect receptacular bracts and labeled ‘“‘fullonum” in 
Linnaeus’ handwriting (Linnaean Herbarium, sheet 119.1) should be 
taken as the lectotype. The cultivated plant then bears the name D. 
sativus, if it is regarded as a distinct species. 


DIPSACUS SATIVUS 


Further confusion exists concerning the author responsible for the eleva- 
tion of var. sativus to specific rank. A number of different authors, in- 
cluding F. A. Garsault (Fig. Pl. Anim. 2: tab. 249. 1764, and 
Traité Pl. Anim. 2: 160. 1767) have been credited with making 
the combination. Since Garsault did not consistently use binomials 
in these works, the combination can not be considered to have been 
published validly by him. The combination has also been erroneously 
attributed to F. A. Scholler (Fl. Barbiensis 47. 1775), who mentioned the 
name only incidentally under Dipsacus fullonum. Most authors have 
attributed the combination D. sativus to G. A. Honckeny (Vollst. Syst. 
Verz. Gewachse Teutschl. 1782). Jackson (Index Kewensis), Schinz 
Thellung, and Mansfeld (see references cited under D. fullonum) cite p.- 
374 for the combination, while Bobrov (Flora URSS) gives p. 16. It has 
developed that Honckeny did indeed make the combination D. sativus 


1965 | FERGUSON & BRIZICKY, NOTES ON DIPSACUS 365 


validly on page 374 of his very rare work of 1782,? although he later 
referred (Syn. Pl. Germania 2: 6.1792) to the cultivated teasel as D. 
fullonum and cited D. sativus C. Bauh. in synonymy, making no reference 
to his earlier work. 

Several modern authors, including Clapham (loc. cit.) and Cronquist 
(Joc. cit.) have treated the two elements of D. fullonum as subspecies. 
The correct subspecific combination D. fullonum L. subsp. sativus does 
not yet appear to have been published properly. Clapham cited Thellung 
as authority, but Thellung (Fl. Advent. Montpellier 490, 491, 680, 697. 
1912) did not make this combination, although he suggested that D. 
sativus may perhaps be a subspecies of D. fullonum and included the 
epithet “sativus” in the index to his work at both specific and subspecific 
rank. Clapham can not be considered to have made a formal new combina- 
tion either, for he does not cite the complete reference to the basionym as 
required by Art. 33, International Code of Botanical Nomenclature, 1961. 

In conclusion, it appears that the nomenclature of these two species of 
Dipsacus may be summarized as follows:

DIstRIBUTION. Mussaenda Kingdon-wardii is an endemic species which 
grows in thickets along the river bed below the high water mark southeast 
of Sumprabum, at an elevation of 300—400 m. above sea level. 


The type collection of Mussaenda Kingdon-wardii consists of two sheets. 
The holotype (pm) has two specimens, one in flower but flowers not avail- 
able for examination, excepting the lower part of one flower, and the 
other i in fruit; the isotype (A) is in fruit only. Only one collection seems 
to have been made of this species. It resembles Mussaenda glabra var. 2 
of Hooker but the leaves are coriaceous and scantily pubescent. Mus- 
saenda Kingdon-wardit is easily distinguished from other species of the 
genus by its linear-lanceolate leaves which are glabrous and shining above 
and pubescent on veins beneath, and by its small, scantily pubescent, 
lenticellate berries with dehiscent calyx. 

I am very grateful to the Keeper of Botany, British Museum (Natural 
History), South Kensington, and to the Curator, herbarium of the Arnold 
Arboretum of Harvard University, for the loan of specimens in their 
charge for this study.

POLLEN MORPHOLOGY IN THE JUGLANDACEAE, I: 
SURVEY OF THE FAMILY 


DoNnALD R. WHITEHEAD 


THE GEOLOGIC HISTORY OF THE JUGLANDACEAE is both extensive and 
diversified. The fossil record of the family, based on megafossils and 
pollen, extends through the Tertiary into the Cretaceous, includes vir- 
tually all extant genera and several extinct ones as well, and embraces 
geographic areas from which the family is either now absent or represented 
by relatively few taxa. In western North America, for example, relatively 
few members of the family are indigenous, yet during the Tertiary species 
of Carya, Engelhardia, Juglans, Platycarya, and Pterocarya occurred. The 
same applies to other regions. It is clear that juglandaceous species were 
important constituents of the Tertiary forests. 

The available pollen morphological studies suggest that grains of most 
genera are distinguishable. A recent investigation has suggested that spe- 
cific identifications of Pleistocene grains may be possible in some cases 
(Whitehead, 1963). However, there are indications of a variational con- 
tinuum (for pore number and pore location) between Pterocarya and 
Juglans and it is conceivable that in extreme cases the separation of Carya 
and Engelhardia might prove difficult. Too few data on variation are 
available to permit a proper analysis of such problems. 

Stachurska (1961) has contributed new information on pollen mor- 
phology in the family and has suggested some possible subdivisions of 
various pollen types. It is evident from her study that there is considerable 
overlap between Juglans and Pterocarya and that the identification of 
individual grains might prove difficult. However, the utility of the paper 
is severely limited by her failure to employ oil immersion optics (thus 
preventing any consideration of fine structure or sculpture) and her use 
of glycerine-jelly as a mounting medium (resulting in anomalous size 
measurements). In addition, a number of critical genera and species were 
not studied. As a consequence, the reliability of some of the observations 
‘and generalizations is questionable. More careful studies embracing a 
greater range of material appear to be needed. 

The present study of the family was initiated with the above considera- 
tions in mind. The material studied includes two species of Alfaroa, 


370 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


seven species of Engelhardia, the one species of Platycarya, 14 species of 
Carya, seven species of Pterocarya, and 16 species of Juglans. Several 
varieties of some species were studied. In general, from one to three 
collections were obtained for each species. More detailed studies of pollen 
size and pore number variation in several taxa have been carried out and 
discussed in a previous paper (Whitehead, 1963). 

The author wishes to express his thanks to Dr. Elso S. Barghoorn who 
first suggested the study and gave many valuable suggestions and to Dr. 
Cortez Hoskins for his helpful comments on a preliminary draft of the 
manuscript. The writer is especially indebted to the directors of the 
Arnold Arboretum (A) and the Gray Herbarium (GH) for permission to 
collect staminate material. Additional collections were provided by Dr. 
Wayne E. Manning and Dr. Donald E. Stone. Slides available in the 
reference collection of the Geological Survey of Denmark (pcu) were 
studied as well. The Jersey Production Research Company kindly granted 
permission to publish the results of the investigation, part of which was 
carried out while the writer was employed as a consultant. The author is 
deeply grateful to Dr. Johannes Iversen and his colleagues of the Geo- 
logical Survey of Denmark for permission to use the facilities of their 
institute and for many stimulating discussions concerning the paper. 
Special thanks are due to Drs. Stone and Manning for their extraordinarily 
careful criticism of the penultimate draft of the manuscript. Support for 
the final phase of the project has been provided by Grant G-17277 from 
the National Science Foundation. 


METHODS 


Whole mounts of pollen grains were prepared as outlined previously 
(Whitehead, 1963; treatment with KOH, acetolysis, and mounting in sili- 
cone oil). Choice of techniques was predicated on the considerations dis- 
cussed by Christensen (1946), Andersen (1960), and Whitehead (1962, 
1964). 

Pollen size measurements for Carya, Juglans, and Pterocarya were car- 
ried out with a high-dry objective (ocular interval = 2.04 micra). Meas- 
urements for Alfaroa, Engelhardia, and Platycarya were made with oil 
immersion (ocular interval = 0.82 micra). Fifty measurements were ob- 
tained for each collection. Pore number and frequency of heteropolar 
grains were noted for Juglans and Pterocarya. 

Of the slides available in the pollen reference collection of the Geologi- 
cal Survey of Denmark, only preparations in silicone oil or Tangelfoot 
medium were selected for study (grains mounted in Tangelfoot are identi- 
cal in size to those mounted in silicone oil (Andersen, 1960)). Supple- 
mentary data on Carya and Juglans have been obtained through the 
courtesy of Dr. Svend Th. Andersen, who, in collaboration with Dr. Stan- 
ley A. Cain, has accumulated a number of observations on the North 
American species of these genera. Andersen and Cain’s data were derived 
from pollen prepared by acetolysis (2 minutes) and mounted in glycerine-

jelly (Andersen, personal communication), hence direct size comparisons 
must be made with caution. However, the nearly perfect concordance of 
these data with those obtained by the author (see TABLE 4) suggests that 
the measurements from glycerine-jelly preparations may be divided by 
1.06 for direct comparison. This corresponds to the correction factor of 
1.15 determined by Faegri and Iversen (1964, pages 169-170). 


THE PROBLEM OF POLLEN SIZE 


It is evident that a variety of factors, both genetic and environmental, 
Operate in concert to influence the size of modern pollen grains. It then 
follows that to obtain meaningful data on pollen size one must accumulate 
measurements from a number of collections distributed over the geographic 
range of the species and encompassing the diversity of ecological situations 
in which it occurs. This also will help minimize the effects of climatically 
aberrant years. As some of the pollen size data presented in this study 
involve only one or two collections, they must be considered preliminary 
and not necessarily characteristic for the particular species. The same 
reservation applies to the data on pore number for /uglans and Pterocarya. 

The size data presented in this investigation will doubtless be compared 
with those of Erdtman (1943, 1952), Heimsch (1944), Wodehouse 
(1935), Stachurska (1961), Stone (1963), and others, thus it is important 
to note that such comparisons must be made with extreme caution. The 
studies of Christensen (1946) and Andersen (1960) demonstrate clearly 
the effect of both chemical treatment and mounting medium on pollen size 
and indicate that direct comparisons are possible only when identical 
techniques have been employed. For example, the measurements of 
Stachurska (1961) are systematically larger than those presented in the 
present study, as she employed acetolysis and mounted the grains in 
glycerine-jelly. 

It should be emphasized that for size studies a medium in which pollen 
size is stabilized must be employed. Glycerine-jelly is not to be recom- 
mended. The unpredictable swelling of grains in this medium is well 
known (e.g., Christensen, 1946; Andersen, 1960; Cushing, 1961; Faegri 
& Deuse, 1960). This is demonstrated by the lack of correspondence be- 
tween many of Stachurska’s measurements (e.g., those for Carya ovalis) 
and those of Andersen and Cain, Stone (1963), and the writer. 

The application of size-frequency data from modern pollen to the iden- 
tification of fossil pollen involves even more complex considerations. 
Seldom can direct size comparisons be made between modern and fossil 
grains. The environment of preservation seems to alter the exine of fossil 
grains chemically so that it does not respond to treatment in the same 
manner as modern pollen (Christensen, 1946; Buell, 1946). Further- 
more, as Andersen (1960) has indicated, pollen grains of a given species 
differ in size depending upon the type of sediment in which they have been 
preserved. Grains are apparently smallest in calcareous sediments and 
largest in more acid types. Consequently, it is often impossible to make 


372 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


direct size comparisons between fossil grains from different levels of the 
same core. These various factors must be considered carefully in any 
application of pollen size data. 


POLLEN MORPHOLOGY 
Alfaroa 


The pollen grains of Alfaroa (TEXT-FIGURES 1-6) are tectate, triporate 
(occasionally with two, four, and five pores), suboblate, subtriangular 
(rounded triangular) in polar view, and possess a fine, even, scabrate 
sculpture. The pores are equatorial in position and may be very slightly 
aspidate. The pore vestibulum is an open, low cone defined by the 
endexine which stops approximately two to three micra short of the pore 
aperture (exopore) leaving a low, ill-defined rim (Trxt-FicuREs 3 and 
5). The ektexine thickens very slightly at the pore. The pore aperture is 
2 to 3 micra in diameter and somewhat variable in shape. According to 
Erdtman (1952) the exopore is meridionally elongated, while in the collec- 
tions studied by the writer it was more or less circular. 

The ektexine is mostly homogeneous, consisting of a relatively thick 
tectum and a much reduced columella layer. The extent of the foot layer 
is not known. Columellae are discernible within the vestibulum, where 
they are visible in optical section (oil immersion only). They are rela- 
tively tightly packed and somewhat irregular in distribution. The pattern 
is best seen with phase contrast. It is apparent that the ektexinous thick- 
ening of vestibulum involves columella layer more than the tectum. 
Columellae could not be differentiated outside of the vestibulum. 

The grains studied varied in size from 18.6 to 28.4 micra, with a mean 
of 23.5 (Tasre 1). This corresponds well to the sizes reported by 
Erdtman (1952) and Heimsch (1944). The exine is approximately 1.6 
micra thick, of which the endexine (and foot layer?) contributes less than 
0.5 micra. The exine appears to be relatively uniform in thickness over 
the entire surface of the grain (except surrounding the pore) in contrast 
to Juglans and Carya in which a distinct thinning of the exine occurs on 
the proximal pole. The scabrate sculpture, consisting of evenly spaced 
elements (less than 0.4 micra in diameter) is present over the entire sur- 
face of the grain, including the vestibulum. It is probable that the 
individual sculptural elements are actually micro-echinae (fine spines) 
comparable to those observed recently with electron microscopy in Juglans 
and Carya (Stone et al., 1964). 

In the collection of A. costaricensis upon which Heimsch (1944) has re- 
ported, 66 per cent of the grains were triporate, 34 per cent tetraporate, 
and less than 1 per cent pentaporate. However, in only one of the collec- 
tions which the present writer studied (A. costaricensis var. costaricensis, 
Skutch 4684) were numbers of tetraporate grains encountered and this 
was clearly an aberrant collection, as the fourth pore was always polar 
rather than equatorial in position. Diporate and tetraporate grains were 
extremely rare in the other collections studied.

Engelhardia ! 

The pollen grains of Engelhardia are tectate, triporate (occasionally 
diporate, tetraporate and pentaporate), suboblate to oblate in shape, tri- 
angular to rounded-triangular in polar view, and possess a fine, even 
scabrate sculpture. Erdtman (1943, page 106) refers to the sculpture of 
E. chrysolepis as “faintly reticulate,” but this represents a misinterpreta- 
tion. The pores are equatorial in position and may be very slightly 
aspidate (TEXT-FIGURES 7-15, 105). The vestibulum is similar to Adfaroa 
(see TEXT-FIGURES 8-10), although in some collections (and species?) it 
cannot be differentiated clearly. The ektexine thickens slightly within the 
vestibulum in grains of E. nudiflora and not at all in E. chrysolepis. In 
the latter species (TEXxT-FIGURE 10) the endopore is elongated equatorially 
(this is partly a function of the oblate shape of the grains), while in 
others it is more or less circular. The exopore (pore aperture) varies in 
shape from elongated (E. chrysolepis) to circular in outline. 

The exine is similar to Alfaroa, with some variation from species to 
species. In Engelhardia chrysolepis it is relatively thin, homogeneous 
(columellae not distinguishable), and does not thicken at the pore. B 
contrast, grains of E. nudiflora and E. pterocarpa are much like those of 
Alfaroa; columellae are discernible in the thickened ektexine near the 
pore. In most collections of E. spicata, E. parvifolia, and E. apoensis a 
rather curious exine structure was encountered (TEXT-FIGURES 13-15); 
the exine appears to undulate sharply giving the grains a distinctly 

crumpled appearance. At first it was thought that this merely represented 
a structural anomaly, either a function of immature grains or of faulty 
preparation. However, the uniformity of the feature, its appearance in 
other collections of E. spicata and E. parvifolia, and the observation of 

e spelling used here, Engelhardia, is the original spelling, ee authors in 
Faves "tees used Engelhardtia, as incorrectly cited in Index Kewensis. See also

surfaces. This would suggest that the feature is due to an uneven 
thickening of the columella layer. Since the scabrate sculpture is present 
even on the concavities it is apparent that at least some tectum is present. 

Individual grains of Engelhardia vary in size from 12.8 micra (E. 
chrysole pis, X= 14.82) to 24.84 (E. spicata var. colebrookiana, X = 
22.0.) (TABLE 2). The exine is generally relatively uniform in thickness 
(ca. one micron) over the entire grain surface (except as noted above). 
The scabrate sculpture, consisting of evenly spaced elements less than 0.4 
micra in diameter, is also present over the whole surface of the grain. 
It is most distinct in grains of E. nudiflora and E. pterocarpa and least 
so in E. chrysolepis. 

Interspecific pollen morphological differences are evident in the genus, 
although a greater range of material must be studied before definite con- 
clusions can be made. Tentatively it can be suggested that there are three 
basic pollen types within the genus. These can be designated arbitrarily 
as E. chrysolepis type, E. nudiflora-Alfaroa type, and E. spicata type 

Grains of the Engelhardia chrysolepis type are distinct. The grains are 
extremely small (12.8-17.4), distinctly triangular in polar view, oblate 
(index 0.57), endopore is elongated equatorially, exopore is elongated 
meridionally, ektexine does not thicken at the pore, no columellae are 
discernible, and the scabrate sculpture is extremely fine. On the basis of 


376 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


the material studied, this type occurs only in E. chrysolepis. This is 
consistent with the findings of Stachurska (1961). 

Pollen grains of the E. nudiflora-Alfaroa type are larger (16.8-23.8,), 
rounded-triangular in polar view, suboblate (index 0.76), endopore is not 
elongated equatorially, exopore is more or less circular, ektexine thickens 
slightly within the vestibulum, columellae are visible within the vestib- 
ulum, and the sculptural pattern is more distinct. This type has been 
found in E. nudiflora, E. pterocarpa, and E. serrata var. cambodica. This 
pollen type is similar in most respects to Alfaroa. 

The Engelhardia spicata type is similar to the E. nudiflora-Alfaroa type, 
but differs in that the grains are apt to be oblate-spheroidal (index 0.89) 
and possess the variable differentially thickened exine. This makes the 
grains angular in polar view (Stachurska refers to these as “hexagonal 
forms”). As mentioned previously, the angularity is due to a sharply 
undulating exine, possibly a function of uneven thickening. Along the 
ridges (thickened areas) columellae can sometimes be seen. In many 
grains of the E. spicata type the vestibulum is not clearly developed. The 
fact that not all of the grains of a sample possess the differential thicken- 
ing and that the degree of expression is variable renders an interpretation 
difficult. The morphological and taxonomic significance of the feature 
can be assessed more properly through the study of thin sections. 

In the present study grains of the E. spicata type were found strongly 
developed in collections of E. spicata, E. spicata var. acerifolia, and E. 
apoensis, and less frequently developed in collections of E. parvifolia and 
E. spicata var. colebrookiana. Stachurska has reported it in E. parvifolia, 
E. spicata, and E. philippinensis (= E. spicata) and to a lesser degree in 
E. colebrookiana (= E. spicata var. colebrookiana) and E. acerifolia t= 
E. spicata var. acerifolia). 


Platycarya 

The pollen grains of Platycarya are tectate, triporate (2-5 pores), 
oblate in shape, triangular in polar view, and possess a fine scabrate 
sculpture (TExt-FicURES 16-24). The grains are unique in possessing a4 
pair of arcuate pseudocolpi on each polar hemisphere. The pores are 
equatorial in position, the endopore is elongated equatorially, and the 
exopore meridionally (TEXT-FIGURE 23). 

The pseudocolpi are distinctive features. They are sharp, slit-like thin- 
nings of the ektexine, involving either the inner portion of the tectum or 
deeper layers of the ektexine. The outer layer of the tectum, although 
sharply invaginated, is continuous over the pseudocolpi, since the scabrate 
sculpture is visible in these regions. The longer of the two pseudocolpi on 
each hemisphere describes an arc of about 12 micra, the shorter one of 
approximately six micra. The functional significance of the structures is 
not known, but their similarity to colpi led Faegri and Iversen (1950) to 
classify the grains as extraporate (possessing both pores and colpi but 
with the pores not included in the colpi). 

The exine is essentially homogeneous and of uniform thickness. Colu-

mellae cannot be differentiated. The scabrate sculpture is present over 
the whole surface, including vestibulum and pseudocolpi, and consists of 
evenly spaced elements (micro-echinae?) less than 0.3 micra in diameter. 

The grains of Platycarya vary in size from 13.1 to 17.2 micra (mean 
about 15.0u) (See TABLE 3).

It is interesting to note that, aside from the presence of pseudocolpi, 


elongated vestibulum and pore aperture, an essentially homogeneous

Carya 

The pollen grains of Carya are tectate, triporate (1-6 pores have been 
observed), suboblate in shape, rounded-triangular to circular in polar 
view, and possess a fine scabrate sculpture (TEXT-FIGURES 25-49, 101- 
104). The grains are distinctly heteropolar; the pores are never exactly 
equatorial in position, but drawn somewhat towards one pole (the distal), 
leaving one hemisphere (proximal) pore-free. Correlated with the hetero- 
polarity is a distinct thinning of the exine on the proximal pole (TExtT- 
FIGURES 25, 26, 33-36). The pore vestibulum is an open, low to greatly 
flattened cone. It is delimited by the endexine which stops approximately 
four to six micra short of the exopore, leaving a low, poorly defined rim 
(TExt-FIcuRES 31, 32, 37). The ektexine thickens quite distinctly within 
the vestibulum; the pore aperture is more or less circular in outline. 

The pollen grains of Carya vary in size from 26.5 (one grain of Carya 
cordiformis) to 63.24 (one grain of C. tomentosa). Mean pollen size 
ranges from 33.3n for C. tonkinensis (one collection) to $0.7 for C. 
tomentosa (11 collections). TABLE 4 summarizes these data and those of 
Stone (1963), Andersen and Cain (personal communication), and Sta- 
churska (1961). In general, grains seem to be largest in section CARYA 
and smallest in section ApocaryA. More important, however, is the 
correlation between ploidal level and grain size (Stone 1961, 1963; 
Whitehead, 1963). The tetraploids of section CARyA possess the largest 


grains. 


378 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


The ektexine of Carya grains is distinctly stratified. This is especially 
evident within the vestibulum, where a distinct thick tectum is present, in 
addition to a well developed columella layer. The endexine, not present 

i t 


(Stone et al., 1964) indicates that the layer identified as endexine with 
light and vihaxse microscopy actually consists of the innermost layer of 
ektexine (foot layer) and endexine. 

The ektexinous thickening near the pore involves two layers of which 
the columella layer is the primary contributor. In most species of Carya 
the columellae can only be seen within the area of the ektexinous thicken- 
ing (which may coincide in extent with the vestibulum or stretch slightly 
beyond it). In general the columellae in this region are highly variable in

size and are irregularly distributed (TExtT-FIcuRES 101-104). Clumping 
of columellae is not infrequent. In only a few species can columellae be 
differentiated in the polar region (and never on the proximal pole), and 
there they are invariably smaller and more tightly packed. There is 
usually a rather uniform gradation from pole to pore, with columellae 
becoming progressively larger and more widely spaced. In some species 
(e.g., C. tonkinensis, TEXT-FIGURE 102) there is a sharp line of demarca- 
tion between polar region and vestibulum. In those species in which the 
columellae are most distinct, there is also a gradient between pole and 
interporium (equatorial region between the pores). The columellae are 
visible in the interporium, but smaller and more tightly packed than in the 
vestibulum. As can be seen in the electron micrographs of Stone ef al. 
(1964), a columella layer is actually present in all portions of the grain; 
columellae, appearing as “variable-sized, anastomosing rods,” can be dif- 


microscopy is therefore partly an artifact caused by limitations of tech- 
nique. Too few data are available as yet to indicate whether columella 
distribution can be used to characterize species, although some possibilities 
appear to be present. These are noted at the end of this section and in the 
discussion. 

e thin polar area poses some problems of interpretation. If one 
follows Stachurska (1961) and Wodehouse (1935), it is not a question of 
a thinning of the exine, but of the exinous thickenings which surround the 
pores coalescing and leaving only the pole free. However, by careful ob- 
servation with light and phase microscopy (oil immersion) it is possible to 
determine the extent of the ektexinous thickening; i.e., the region within 
which the columellae can be differentiated most readily and within which 
they have the most irregular distribution. In those species which possess 
the most extensive ektexinous thickening (continuing beyond the vestib- 
ulum and encroaching upon distal pole and interporium, e.g., Carya 
cordiformis, TExT-FIGURE 103), the interpretation of Stachurska and 
Wodehouse would seem to fit. However, even in such types it can be seen 
that the polar thinning is considerably more restricted in area than the 
region covered by the ektexinous thickening. Furthermore, in Carya tonki- 
nensis (TEXT-FIGURE 102) the thickenings are confined to the vestibulum 
(which itself is highly restricted), yet a distinct polar thinning is visible 
(TEXT-FIGURE 33). It would thus seem that the polar thinning is a 
feature unrelated to the exinous thickenings surrounding the pores. The 
thinning probably involves largely the columella layer as columellae are 
never visible in this region, and since the scabrate sculpture is continuous 
over the thinning. This interpretation has been corroborated by electron 
microscopy (Stone et al., 1964 

As suggested above, it is extremely difficult to attach any taxonomic 
significance to the morphological features observed. There is great varia- 
tion from collection to collection and occasionally within a collection as 
well. This is true with respect to the frequency of tetraporate grains, 
columella distribution, character of the ektexinous thickening, degree of

heteropolarity, etc. Stachurska’s pollen groups seem to be more a reflec- 
tion of the particular grains studied than characteristic of the species in 
question. This is certainly true with respect to pore frequency, extent of 
the exinous thickening, and position of the pores. The author found no 
grains with truly equatorial pores in any of the collections studied, al- 


382 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


though less heteropolar grains were found in a few species (eg., C. 
tonkinensis, C. sinensis, C. illinoensis, etc.). 

The observations on fine structure made in the course of the investiga- 
tion are summarized in the following paragraphs. 

Section Carya. (1) Carya glabra (2 niet columellae within 
vestibulum large and distinct, irregular in size and distribution. Colu- 
mellae visible on distal pole are small and tightly packed. Uniform grada- 
tion from pole to both pore and interporium. Columellae visible in inter- 
porium, but very tightly packed. (2) C. laciniosa (2 collections): arrange- 
ment of columellae as for C. glabra. (3) C. leiodermis (1 collec aay 
morphology as for two preceding species, but structure finer, columellae 
not discernible on pole and interporium. (4) C. ovalis (2 collections) : 
structure intermediate between C. glabra and C. leiodermis. Some colu- 
mellae visible on distal pole, but very fine and tightly packed. (5) C. 
ovata (3 collections): much variation from collection to collection; one 
similar to preceding species, with very fine columellae visible on inter- 
porium; another with extremely coarse and widely spaced columellae 
within vestibulum and distinct large columellae on the distal pole; a third 
with an extraordinarily thick tectum and columella layer within the vestib- 
ulum. (6) C. pallida (1 collection): ektexine within the vestibulum 
unusually thick (reported also by Stachurska), exine varies in thickness 


Columella distribution as in grains of C. glabra. (7) C. texana var. 
arkansana (2 collections): grains more regular than in the preceding 
species, outline regularly rounded-triangular. Vestibulum sharply defined. 
Abrupt transition from vestibulum to polar area. Very large and irregu- 
larly distributed columellae within vestibulum; columellae not visible on 
rest of grain surface. (8) C. tomentosa (11 collections): In general, 
columellae visible on both interporium and distal pole, with a gradation 
from both pole and interporium to vestibulum (and from pole to inter- 
porium) (TEXxtT-FIGURE 104). Packing of columellae is variable. 

Section Apocarya. (1) C. aquatica (2 collections): collections variable, 
one with uniform gradation from pole to pore zone and with columellae 
relatively tightly packed within pore zone and not visible on the pole; the 
other with a sharp line of demarcation between polar zone and pore zone, 
and columellae within pore zone very large and widely spaced. (2) C. 
cordiformis (11 collections): Much variability is evident. In general, the 
ektexinous thickenings are extensive and encroach upon both interporium 
and distal pole (Text-ricurE 103). The columellae within the ektexinous 
thickenings are usually large and irregularly spaced. Some collections 
have an unusually wide spacing of columellae, giving the vestibulum an 
essentially “empty” look (Trxt-Fricure 103). In some collections there 
is a gradation from pole to pore, in others an abrupt change (the latter 
condition seems to prevail in two collections of C. cordiformis var. lati- 
folia). (3) C. illinoensis (2 collections): the pollen grains appear to be 
more triangular than in many of the preceding species, apparently due to 
a distinct, localized thickening of the ektexine at the pore. The grains 


1965] WHITEHEAD, JUGLANDACEAE, II 383 


also tend to be a little less heteropolar. Both the vestibulum and ektexi- 
nous thickening are restricted in area and there is a sharp contrast in colu- 
mella pattern between this region and the polar hemispheres. Within the 
pore zone the columellae are highly irregular in size and shape. The rela- 
tively small area covered by the ektexinous thickening corresponds to the 
reports of Wodehouse (1935) and Stachurska (1961). (4) C. myristict- 
formis (2 collections): columella distribution gradational from pole to 
pore, columellae not visible on pole. A few “islands” of tightly packed 
fine columellae are evident on the distal pole of a few grains from one 
collection. The columellae within the vestibulum are more uniformly 
distributed and more tightly packed than in most species. (5) C. tonki- 
nensis (1 collection): pollen grains are very small; pores more equatorial 
than in other species; endexine break at border of vestibulum more dis- 
tinct than in most; vestibulum and ektexinous thickening very restricted. 
Columellae visible only within the vestibular area. Columellae large, ir- 
regular, and widely spaced (TExtT-FIGURE 102). Sharp lines of demarca- 
tion between vestibulum and polar zone (partly due to break in endexine, 
partly to the change in columella distribution). There is an apparent con- 
centration of columellae at the base of the vestibulum (near the endexine 
break) and also around the aperture. 

Section RHAMPHOCARYA. (1) Carya sinensis (1 collection): grains rela- 
tively small (see also Stone, 1963), somewhat more triangular in polar 
view than other species, and a little less heteropolar. Vestibulum restricted 
as in C. tonkinensis, and defined by a rather sharp break of the endexine. 
Ektexinous thickening restricted in area, sharp line of demarcation be- 
tween pore area (within which are large, irregular, widely spaced colu- 
mellae) and polar hemispheres (TEXT-FIGURE 101). Thinning of proximal 
pole as in all other species. 

On the basis of size, restricted ektexinous thickening, slightly protuber- 
ant pores, and relative isopolarity, grains of Carya tonkinensis and C. 
sinensis approach those of the Engelhardia nudiflora-Alfaroa type. This 
might indicate that grains of these species are primitive for the genus. 
Should this assumption be valid, then one may suggest that the evolu- 
tionary trends within the genus (with respect to pollen morphology) 
would be towards increased pollen size, increased heteropolarity, more ex- 
tensive ektexinous thickenings and the development of larger and more 
distinctive columellae. Pollen size and heteropolarity are to a degree re- 
lated, and the ektexinous thickenings and columella patterns are certainly 
related. However, the former two and latter two could be thought of as 
relatively independent evolutionary trends. 

The grains of Carya sinensis are worthy of further comment, especially 
considering the varied opinions held concerning the taxonomic position of 
the species (e.g., Manning and Hjelmqvist, 1951; Scott, 1953; and Leroy, 
1952, 1953). On the basis of pollen morphology alone, the taxon would 
appear to be closely allied to Carya. The grains are clearly Carya-like; in 
fact, indistinguishable from those of many of the species. This would cer- 
tainly support the conclusions of Manning and Hjelmqvist (loc. cit.) who 


384 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


have placed it in section RHAMPHOCARYA of the genus Carya. As was 
suggested to the writer by Stone (personal communication) the greater 
degree of triangularity of Carya sinensis grains (compared to C. tonki- 
nensis), a condition noted in grains of the Alfaroa-Engelhardia nudiflora 
type, indicates that the sinensis type might be more primitive than the 
tonkinensis type. 


Pterocarya 


The pollen grains of Pterocarya are prevailingly stephanoporate, possess 
from three to nine pores (the mean figure is roughly 5.8 for the genus), 
are polygonal to circular in polar view, oblate to suboblate in shape, and 
have a distinct scabrate sculpture (TEXxT-FIGURES 80-100, 106). The 
pores are distinctly aspidate, the ektexine generally thickens perceptibly 
within the vestibulum, and the pore aperture varies in shape from circular 
(TEXT-FIGURE 92) to elongate (TEXT-FIGURE 91). Elongate apertures 
tend to be more frequent than circular ones. The grains, although char- 
acteristically stephanoporate, are occasionally periporate and heteropolar 
as in Juglans (TExt-FicuRES 92-94). This condition is most prevalent in 
grains with seven or more pores. The heteropolar grains generally possess 
only one or two pores on the distal surface, the remaining pores being 
strictly equatorial in position. The frequency of heteropolar grains varies 
from collection to collection. It is lowest in one collection of Pterocarya 
paliurus (0%) and highest in a collection of Pt. rhoifolia (34%) (see 
TABLE 5). Some tendency towards heteropolarity can be found in many 
other stephanoporate grains in that one or two pores may be positioned 
slightly off of the equator, and the grains are often slightly plano-convex 
in equatorial view. No evidence of any ektexinous thinning on the proxi- 
mal side has been found. 

Grains of Pterocarya vary in size from 25.9 (one grain of Pt. paliurus) 
to 38.84 (several species). Mean pollen size varies from 28.6n (Pt. hupe- 
hensis, \ collection) to 35.5, (Pt. insignis, 1 collection). Pore number 
varies from 3 to 9. Species’ means range from 4.1 (Pt. paliurus) to 6.5 
(Pt. rhoifolia). (For the purpose of these discussions, Stachurska’s obser- 
vations on Pt. rhoifolia have been omitted. The collection that she studied 
had unusually high pore number for the genus (7.6), an unusually high 
percentage of heteropolar grains (75%), and the modal class for pollen 
size was larger than for other species of Pterocarya. It is likely that this 
herbarium sheet was identified incorrectly and represents instead a species 
of Juglans (possibly J. cathayensis).) 

The individual collection data for mean pore number and mean pollen 
size are plotted on a scatter diagram (F1cuRE 108). 

The exine of Pterocarya grains is relatively homogeneous. Columellae 
can never be distinguished outside of the vestibular region and are often 
difficult to discern even within that zone. The ektexine thickens very 
slightly at the pore. Both tectum and columella layer are involved in this 
thickening. The vestibulum of the pore is a relatively distinct feature,

partly because the endexine breaks off sharply at the base of the vestib- 
ulum and partly because there is a concentration of columellae at that 
point and around the aperture. The remainder of the ektexine within the 
vestibulum is often free of columellae. 

With the exception of low pore number in Pterocarya paliurus (section 
Cyc.optera) there appear to be no morphological criteria which have any 
intrageneric taxonomic significance.

Juglans 

The pollen grains of Juglans are relatively variable. They (TEXT- 
FIGURES 50-79, 107) are tectate and basically periporate and heteropolar. 
The pores are restricted to one polar hemisphere or may encroach slightly 
upon the other. Pore number varies from two to 37 for the genus, al- 
though individuals with from 6 to 18 pores are most frequent. The mean 
pore-number varies from a minimum of 7.3 for J. cathayensis (2 collec- 
tions) to a maximum of 17.4 for J. nigra (42 collections; Whitehead, 
1963). The pores are apt to be strictly equatorial in grains with low pore 
number, hence such grains can be classified as stephanoporate (TEXT-

FIGURES 68-70). The frequency of stephanoporate grains is variable and 
is highest in one collection of Juglans cinerea (35%) (See TaBLe 6 for 
further data). The grains are either circular or polygonal in polar view. 
Grain shape varies from suboblate to oblate-spheroidal. A distinct thin- 
ning of the ektexine occurs on the pore-free (proximal) pole (TEXT- 
FIGURES 58-62). The sculpture is distinctly scabrate. 

The pores are generally aspidate, but the degree is highly variable 
(TEXT-FIGURES 69, 77). The vestibulum varies accordingly from a low, 
flattened cone to a fairly steep-sided one. The ektexine usually thickens 
slightly within the area of the vestibulum. In occasional grains the 
thickening is extremely pronounced (TExt-FIcuRE 71). The pore aper- 
ture ranges from circular to elongate in shape. 

The pollen grains of Juglans vary in size from a minimum of 24.5» (one 
grain of Juglans major) to a maximum of 50.0u (one grain of J. regia). 
The species’ means range from 30.3 for J. boliviana (1 collection) to 
42.6u for J. regia (3 collections). 

Individual collection data for pore number and pollen size are plotted 
in the scatter diagram (Ficure 108).

The exine is of relatively uniform thickness over the entire grain surface 
except on the pore-free pole and within the vestibulum. The polar thin- 
ning appears to be similar to that observed in grains of Carya, and proba- 
bly involves reduction of the columella layer. This has been corroborated 
by electron microscopy (Stone et a/., 1964). As the scabrate sculpture is 


390 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


continuous over the thinning, at least some tectum must be present. The 
thinning is not detectable in stephanoporate grains. The exine appears to 
be relatively homogeneous. Columellae cannot be differentiated outside 
of the vestibular region and are often difficult to observe even within it. 
Once again, this observation appears to be based on an artifact of tech- 
nique, since application of electron microscopy has shown that the colu- 
mella layer occurs in all portions of the grain (Stone ez al., loc. cit.). The 
most usual situation is to find columellae concentrated at the base of the 
vestibulum (TExT-FIGURE 107) and around the pore aperture. There is 
usually a columella-free zone of variable width between these two regions 
of concentration, although narrow “flames” of columellae may extend 
into 

The sculptural pattern is continuous over the entire surface, including 
both vestibulum and proximal pole. It varies in distinctness from collec- 
tion to collection, but is generally visible only under oil immersion. It ap- 
pears to be most distinct in collections of J. regia, which also possess the 
largest grains, 

Pollen size and pore number appear to have some taxonomic significance 
within the genus Juglans. This is clearly indicated on the scatter diagram 
(Ficure 108). The species of section CARDIOCARYON are characterized by 
low pore number (means from 7.2 to 8.6 for individual collections), a 
higher frequency of stephanoporate grains (obviously correlated with pore 
number), and pollen grains ranging in size from approximately 33 to 39 
micra. Pollen size is approximately the same for section RHYSOCARYON, 
but mean pore number is distinctly higher. It ranges from a minimum of 
9.7 in J. jamaicensis to 17.4 in J. nigra. Pollen grains of Juglans regia 
(section DioscaRYoN) have approximately the same pore number as those 
of section Ruysocaryon, but are distinctly larger. It would appear that 
grains of the Cardiocaryon type, which are similar to those of the less 
advanced genus Pterocarya, are primitive for the genus, and that the pri- 
mary evolutionary trends have been towards an increase in pore number 
ena in J. nigra) and an increase in pollen size (leading to J. 
regi 

The markedly higher pore number characteristic of grains of Juglans 
nigra suggests that that species has occupied a position isolated (geo- 
graphically and/or genetically) from other species of section RHYSOCARYON 
for some time. Similarly, the relatively small grain size and low pore 
number of the tropical American species of section Ruysocaryon (J. 
olanchana, J. australis, J. insularis, J. neotropica, J. boliviana) suggests 
their early separation from other species of the section and retention of 
more “conservative” pollen morphological features. 

The plotted points for the two collections of J. microcarpa pose a prob- 
lem. One (Palmer 11327, from Texas) falls within the J. nigra region of 
the scatter diagram, while the other (Greene, 1880, from New Mexico) 
plots near the two New Mexico collections of J. major. It would be in- 
structive to review the taxonomic status of the collections in question. 
For example, Manning (personal communication) has suggested that J.

has not utilized the pollen groups established by Stachurska (1961) as, in 
general, they are based on characteristics (roundness of grains, protu- 
berance of pores) that are apt to be profoundly altered by the state of 
preservation of the preparation; specifically the state of expansion of the 
grains. In fact, a number of Stachurska’s photomicrographs (e.g., Plate 
II) are of grains which have been distended greatly by the swelling that 
one often encounters in glycerine-jelly preparations. ; 

Following is a summary of observations on all Juglans collections 
studied. 

Section Ruysocaryon Dode. (1) Juglans australis: A few stephano- 
porate grains noted. This is highly unusual for the section. Distribution 
of columellae within vestibulum variable. (2) J. boliviana: distribution 
of columellae within vestibulum essentially “concentric,” i.e., columellae 
si Nance around exopore and endopore, few between. (3) J. califor- 
nica: “concentric” arrangement of columellae within vestibular area; a 
band of clumped columellae surrounding the pore aperture and another 
band at the base of the vestibulum. (4) J. irsuta: columellae tightly 
packed within vestibulum, only a narrow, relatively columella-free zone 
between aperture and base of vestibulum. (5) J. insularis (J. jamai- 
censis): pore zone (vestibulum) relatively sharply defined; large and 
irregular patches of columellae at base of vestibulum and around the pore 
aperture; columellae widely spaced in between. (6) J. major: great 
variation from collection to collection. Both of the New Mexico collec- 
tions have many grains with grossly protuberant pores and an extremely 
irregular scabrate sculpture. The other collections are more typical for 
the genus. Variation in fine structure is comparable; in some grains the 
pore zone is sharply defined by a definite concentration of columellae at 
the base of the vestibulum (Ficure 107), in other grains there is a 
gradual transition from the homogeneous extra-vestibular exine to pore 
region. (7) J. microcarpa: considerable variation (see also previous dis- 
cussion). Vestibulum structure as described for J. californica, with narrow 
columella-free zone between aperture and base. (8) J. neotropica: grains 
more rounded than in most collections, pores barely aspidate. Pore zone 
(vestibulum) relatively sharply defined; many large, irregularly distrib- 
uted columellae within the zone. (9) J. nigra: vestibulum quite sharply 
defined; broad relatively columella-free zone extending from aperture 
nearly to base of vestibulum. Zone of columellae around pore aperture 
very narrow. Irregular “flames” of columellae extend from base of vestib- 
ulum into the columella-free area. (10) J. olanchana: many grains with 
unusually thick ektexine at the pore, great variability. Somewhat irregular 
distribution of columellae within the vestibular zone. 

Section Dioscaryon Dode. (1) J. regia: pore apertures appear to be 
unusually large. Sculpture often very distinct. A broad zone with large, 
irregularly spaced columellae around aperture; a rather diffuse zone of 
widely spaced columellae between this sd the base of the vestibulum. 
Concentration of columellae also in basal zo

DISCUSSION 


Generic distinctions. There are four different pollen types within the 
Juglandaceae: the triporate-isopolar Engelhardia-Alfaroa type; the tri- 
porate-pseudocolpate Platycarya type; the triporate-heteropolar Carya 
type; and the stephanoporate to periporate-heteropolar Juglans-Pterocarya 


type. 

Pollen grains of the Engelhardia-Alfaroa type can be distinguished as 
follows: the pollen grains of Platycarya, although basically similar, always 
possess characteristic pseudocolpi. Grains of Carya are considerably larger 
(largest Engelhardia-Alfaroa grains: 26.24; smallest Carya grains: 26.5») 
are always heteropolar and possess an ektexinous thinning on the proximal 
pole. Also, grains of Carya tend to be more circular in polar view and 
have much more distinctive columellae within the vestibular area. Pollen 
grains of the Juglans-Pterocarya type are larger, have a higher pore num- 
ber, and tend to have more aspidate pores. Triporate-isopolar Pterocarya 
and Juglans grains do occur, but they tend to be larger and have more 
aspidate pores. 

The pollen grains of Platycarya strobilacea can be distinguished easily 
from those of all other taxa in the family by virtue of the distinctive 
pseudocolpi. These are invariably present, even on tetra- and pentaporate 
grains, 

The combination of three pores, heteropolarity, polar thinning, distinc- 
tive columellae and relatively large grain size serves to distinguish Carya 
grains from all other types. As mentioned above, the grains are invariably 
larger than those of the Engelhardia-Alfaroa type, are always heteropolar 
and possess the distinctive ektexinous thinning. The triporate Juglans- 
Pterocarya grains have equatorial, more aspidate pores, lack the localized 
polar thinning, and have a somewhat thinner exine. Furthermore, the 
columellae within the vestibular zone are not as large, distinct, or as 
irregularly distributed as in Carya grains. The diporate and tetra- to 
hexaporate grains of Carya are also easily recognizable. 

Within the Alfaroa-Engelhardia group it would appear that a reliable 
generic distinction cannot be made on the basis of pollen morphology. 
However, it must be admitted that significantly more material of the two

genera must be studied before this possibility can be ruled out. On the 
basis of the material investigated, it is apparent that the grains of Alfaroa 
are distinguishable from at least one of the three Engelhardia pollen types 
(the E. chrysolepis type) and may be distinguishable from another (the 
E, spicata type). However, grains of Alfaroa and the Engelhardia nudi- 
flora type appear to be indistinguishable. Pollen grains of the E. chry- 
solepis type are much smaller than those of Alfaroa (14.4 vs. 23.0 micra), 
are distinctly triangular (vs. rounded-triangular), are oblate (vs. sub- 
oblate), have an equatorially elongated endopore (vs. a circular one), the 
ektexine does not thicken within the vestibulum, and columellae cannot be 
differentiated (they are visible within the thickened ektexine of the vestib- 
ulum in Alfaroa grains). The distinctions between Alfaroa grains and 
those of the E. spicata type are by no means so certain, partly because it 
is not clear whether the E. spicata type represents a distinct “species” or 
rather an anomalous variant of the Z. nudiflora type. Grains of the E. 
spicata type tend to be more spheroidal, the vestibulum is often less dis- 
tinct, and the exine is often sharply undulating, perhaps due to an un- 
evenly thickened ektexine. 

The grains of Juglans and Pterocarya are very similar. The variational 
extremes appear to be relatively distinct (e.g., tetra- and pentaporate, 
stephanoporate grains of Pterocarya and periporate, heteropolar grains of 
Juglans (§ Ruysocaryon and § Drioscaryon). However, as is evident 
from the scatter diagram, the photomicrographs, and the data presented in 
TABLES 5, 6, and 7, there is a variational continuum from Pterocarya to 
Juglans section CARDIOCARYON. Pore number, grain size, and frequency 
of heteropolar grains tend to be higher in section Carpiocaryon, but 
there is overlap for all of these characteristics. Pollen size cannot be used 
because there is a general correlation between pollen size and pore num- 
ber; those grains of Juglans (§ CARDIOCARYON) with the lowest pore 
number are also smallest. Furthermore, the heteropolar tendency is detec- 
table in many stephanoporate Pterocarya grains in that one pore is apt to 
be positioned slightly off of the equator and the grains are often somewhat 
plano-convex in equatorial view. Other morphological criteria are equally 
difficult to apply. The pore aperture in Pterocarya is apt to be elongated 
meridionally, but this is by no means constant. Pterocarya grains are 
generally more oblate in shape, but this characteristic is associated with 
pore number and degree of heteropolarity; heteropolar grains are more 
spheroidal (and stephanoporate-isopolar Juglans grains are more oblate 
than heteropolar ones). The polar ektexinous thinning is not a definitive 
characteristic, because it is not present in stephanoporate Juglans grains, 
and is extremely difficult to detect (and possibly absent) in many hetero- 
polar grains with relatively low pore number. There are no apparent dif- 
ferences in columella distribution. 

Grains with from 6 to 8 pores are extremely difficult to identify with 
certainty. However, certain suggestions can be made on the basis of the 
data presented in TaBLE 7 and Ficure 109. It can be seen that five- and 
six-pored grains are much more frequently encountered in Pterocarya,

that seven-pored grains are met with frequently in both taxa, and that 
eight- and nine-pored grains are much more common in members of 
Juglans section CARDIOCARYON. Furthermore, there is an obvious differ- 
ence between taxa within each pore-number class, since the frequency of 
stephanoporate grains is consistently higher in Pterocarya. For example, 
97 per cent of hexaporate Pterocarya grains are stephanoporate, and only 
44 per cent of Juglans ($ CARDIOCARYON) grains; and 71 per cent of 
seven-pored Pterocarya grains are stephanoporate, 4 per cent of Juglans. 

Such data are instructive, but must be handled with extreme caution, 
since a number of assumptions are involved. First, when dealing with 
fossil material, it would be necessary to assume that the populations of 
Juglans and Pterocarya which contributed pollen to the depositional basin 
in question possessed pore-number and heteropolar-frequency characteris- 
tics comparable to those determined in the present study. Secondly, since 
relatively few collections were studied, there is no guarantee that the data 
are representative for the two taxa. Furthermore, it is quite possible that 
significant interspecific and intraspecific differences in populations may 
exist for both characteristics (this could apply to both modern and fossil 
material). This possibility can be visualized from the histograms for ex- 
treme individual collections which are also presented in TEXT-FIGURE 2. 
(This should not be construed as proof of the existence of such differences 
in populations, merely as a hypothetical example.) If, for example, the 
populations of Juglans and Pterocarya growing in the vicinity of a deposi- 
tional basin possessed frequency characteristics similar to those of the 
individual collections of Juglans cinerea and Pterocarya rhoifolia, separa- 
tion of grains would be virtually impossible. On the other hand, the 
presence of populations with characteristics approximating those for Jug- 
lans sieboldiana and Pterocarya insignis would make discrimination con- 
siderably easier. A further complication is that the distributions (for pore 
number and frequency of heteropolar grains) determined in the present 
study may be derived, the result of a long evolutionary sequence. It seems 
probable that within the Juglans-Pterocarya complex small pollen size, 
low pore number and low frequency of heteropolar grains are primitive 
characteristics. Hence one would expect Juglans section CARDIOCARYON 
grains from the early Tertiary to have characteristics more closely approxi- 
mating those of modern Pterocarya species. Similarly, one might expect 
lower pore number within the early Tertiary species of Pterocarya. 

It must be concluded that individual Pterocarya-Juglans section CARDIO- 
CARYON grains will pose a difficult problem. If such grains are sufficiently 
common, it would be instructive to prepare a statistical analysis of pollen 
size, pore number, and frequency of heteropolar grains. This would allow 
more reasonable suggestions as to the taxa involved and provide a more 
meaningful basis for the delimitation of form genera and form species. 


Subgeneric categories. The degree to which subgeneric identifica- 
tions can be made is suggested by the following key to generalized pollen 
types. It should be emphasized that specific identifications are not im-

When one disregards the variational extremes for all taxa and considers 
only the most frequently occurring values for both quantitative and quali- 
tative characteristics, it is clear that a more precise subdivision of some 
of the pollen types is possible. While little can be done with Engelhardia- 
Alfaroa and Platycarya poses no problem, more precise assignments can 
be made within the Juglans-Pterocarya complex. Pollen morphology 
could also be of considerable use within Carya, but is more difficult to 


ploy. 

The following suggestions can be made with respect to the Juglans- 
Pterocarya complex. Stephanoporate grains (3—7 pores) are most proba- 
bly those of Pterocarya; especially those that are less than 32, in size. 
Periporate-heteropolar grains with low pore number (6-9) are apt to be 
from Juglans section CARDIOCARYON (generally 33~39, in size). Peri- 
porate-heteropolar grains with from 9 to 13 pores and of relatively small size 
(30-354) may belong to the tropical American complex (J. australis, J. 
boliviana, J. insularis, J. neotropica, and J. olanchana). Somewhat larger 
grains (33-39) with from 9 to 16 pores can be assigned to Juglans section 
Ruysocaryon. Grains with more than 16 pores are those of Juglans nigra 
(size: 33-36). Grains larger than 394 with from 11 to 15 pores are those 
of Juglans regia. 

In addition, a few generalizations can be made concerning Carya pollen. 
First, it is obvious that there is a correlation between pollen size and 
ploidal level (Stone, 1961, 1963; Whitehead, 1963). In general the 
smallest grains occur in the diploids of section Apocarya, the largest in 
the tetraploids of section CARyA. There are obvious exceptions. For ex- 
ample, Carya illinoensis (2n) of section Apocarya has rather large grains 
(mean = 46.14) and Carya floridana (4n) of section Carya has rather

small pollen (reported by Stone (1963)) to be 44.1. This latter mean is 
from fresh grains mounted in cotton-blue-lactophenol. By applying a cor- 
rection factor of — 1.03, it can be suggested that it would correspond to 
42.8» for grains treated as in the present study. Small grains are also 
found in Carya sinensis of section RHAMPHOCARYA, 

Relatively isopolar grains have been observed in Carya tonkinensis, and 
Carya illinoensis and in C. sinensis. As is mentioned previously, this is a 
difficult criterion to employ, since it can be influenced profoundly by the 
state of compression of the grains. 

Some species possess grains with a sharply defined and somewhat re-

illinoensis and the single collection of Carya pallida (§ angen It has also 
been aon for the latter species by Stachurska (1961 

pollen grains of Juglans regia and Carya Mienenais are of further 
ie because of their relatively large size. The mean for Juglans regia 
(43) is considerably larger than that for other species of the genus 
(means usually 32—36,) and the grains of C. illinoensis (mean = 46) are 
much larger than those of other species of section Apocarya and as large 
as those of the tetraploids of section Carya. Stone (1963) has also noted 
this for C. illinoensis, and has suggested that large grain size might be 
correlated with increased fertility, as is the case in other taxa. It is signif- 
icant that both of these species have had a long history of cultivation, 
hence the recent evolutionary trends within the species may be largely 
controlled by the selective pressures imposed by man. Certainly increased 
fertility would be selected for, and if pollen grain size were correlated, as 
seems likely, it is reasonable to suggest that the evolution of larger pollen 
in these taxa has been a relatively recent phenomenon, stimulated and 
directed by man’s practices. 


Phylogenetic considerations. Pollen morphology supports the indi- 
cations from floral morphology (Manning, 1938, 1940, 1948) and wood 
anatomy (Heimsch & Wetmore, 1939) as to relationships of genera. The 
correlated evidence from these previous studies indicates that the Engel- 
hardia-Alfaroa complex (see also Manning, 1949) is primitive and that the 
Juglans and Carya lines are relatively advanced. Pterocarya appears to 
occupy an intermediate position, relatively close to Juglans. Platycarya 
presents some interesting problems, being advanced with respect to wood 
anatomy (Heimsch & Wetmore, loc. cit.) and primitive with respect to 
type and bearing of inflorescence (Manning, 1938). 

When speculating on the evolution of pollen types within the family, it 
would be reasonable to look for the most primitive grains within the 
Engelhardia-Alfaroa group and the most advanced in Juglans and Carya 
(and Platycarya?). The grains of the Engelhardia-Alfaroa are small, pre- 
vailingly triporate, and isopolar ; those of Juglans and Carya larger, hetero- 


primary evolutionary trends have involved an increase in pore number, 

grain size, and heteropolarity. To some extent these trends have been 

independent of one another. The general trends are indicated in FIGURE 
1 


Within Engelhardia and Alfaroa there are at least two pollen types 
represented: first, the very small, triangular, oblate E. chrysolepis type, 
secondly, the larger, more spheroidal E. nudiflora-Alfaroa type. The E. 
spicata type is problematical, and may be nothing more than an aberrant 
variant of the basic EF. nudiflora type. For the moment it will be disre- 
garded. On the basis of wood anatomy (Heimsch & Wetmore, 1939) and 
floral morphology (Manning, 1938, 1949) Alfaroa appears to be the most 
primitive member of the family. It would then be logical to suggest that

pollen grains of the £. nudiflora-Alfaroa type, found also in this genus, 
are the most primitive, and that the E. chrysolepis type has been derived 
through a reduction in pollen size, increasing angularity, and reduction of 
columellae. However, there are several arguments against this view. 
First the general trend within the family appears to have been an increase 
in grain size and an increase in the distinctiveness of columellae. The evo- 
lution of the E. chrysolepis type from the E. nudiflora-Alfaroa type 
would require a reversal of this. Secondly, the remarkable similarity of 
Platycarya and E. chrysolepis type pollen may be of significance. Should 
Platycarya grains lack pseudocolpi, they would be virtually indistinguish- 
able from those of the E. chrysolepis type. Both grains are extremely 
small, triangular, oblate, have a meridionally elongated exopore and an 
equatorially elongated endopore, and a homogeneous exine (it does not 
thicken within the vestibulum and no columellae can be differentiated). 
The scabrate sculpture of both types is extremely fine (a function of grain 
size) and uniform. All these features suggest that the Platycarya type has 
evolved from the E. chrysolepis type through the development of localized 


406 JOURNAL OF THE ARNOLD ARBORETUM [VoL. 46 


arcuate thinnings of the ektexine (reduction of columella layer and inner 
tectum). Should this suggestion be valid, then it is more logical to assume 
that the E. chrysolepis type is primitive, and that the Platycarya and E. 
nudiflora-Alfaroa types are evolved (also the E. spicata type). In this 
context, it is perhaps significant that both Platycarya and Engelhardia 
chrysolepis possess inflorescence types (terminally placed androgynous 
panicles) which Manning (1938) considers to be the most primitive for the 
amily 

From the triporate-isopolar base there were _apparently two primary 


through Pterocarya and culminating in Juglans nigra (high pore number) 
and Juglans regia (large pollen grains). 

It is difficult to ascribe evolutionary significance to the pollen morpho- 
logical characteristics observed within the genus Carya, since the features 
are subtle and display great variation. However, it is probable that the 
most primitive grains would be those most closely approximating the 
Engelhardia-Alfaroa type, i.e., small size, relative isopolarity, restricted 
ektexinous thickening and vestitiahim, Such grains are found in various 
species of section Apocarya and also in Carya sinensis (§ RHAMPHO- 
carvA). The grains of Carya tonkinensis and C. sinensis are more similar 
to those of Engelhardia-Alfaroa than those of other species, hence may 
represent the most primitive type. This situation is not unexpected, since 
preliminary evidence indicates that species of section APOCARYA are primi- 
tive (Stone, 1962) and that Carya tonkinensis may be the most primitive. 
Wood of this species is less distinctly ring porous and possesses more 
heterogeneous rays than that of other species (Heimsch & Wetmore, 1939). 
More recently (Leroy, 1953) it has been shown that the wood of Carya 
sinensis is virtually indistinguishable from that of C. tonkinensis. 

The larger, more heteropolar grains of section Carya, especially those 
of the tetraploids, can be considered more advanced. The recognizable 
variants of the Apocarya type (e.g., C. cordiformis and C. illinoensis) 
are doubtless short side lines. 

The last pollen type to be considered is that found in Juglans and 
Pterocarya. Following the evolutionary sequence suggested for the family 
as a whole it seems probable that the relatively small stephanoporate 
grains of Pterocarya are more primitive than those of Juglans. This is in 
harmony with the intermediate position suggested by morphological and 
anatomical studies (Heimsch & Wetmore, 1939; Manning, 1938). 

Since there appears to be a continuum between Pterocarya and Juglans, 
it is interesting to speculate on the relationship of these genera. On the 
basis of pollen morphology alone the relationship would appear to be close. 
This is also suggested by wood anatomy (Heimsch & Wetmore, 1939) and 
floral morphology (Manning, 1938, 1940, 1948). The present study indi- 
cates that the relationship is closest between species of the section 
CarpIocaryon and Pterocarya (see, for example, the scatter diagram). 


1965] WHITEHEAD, JUGLANDACEAE, II 407 





This alliance is also supported by the evidence from wood anatomy and 
floral morphology. Heimsch and Wetmore (loc. cit.) have noted that 
species of Cardiocaryon have vascular elements with thinner walls than 
those of other species in the genus as a whole. This condition is similar to 
that prevailing in Pterocarya. Furthermore, species of section Carp1o- 
CARYON differ from the rest of the genus in possessing more flowers (12— 
20) per pistillate catkin (Manning, 1938) and fewer stamens (7-18) per 
staminate flower (Manning, 1948). In both of these characteristics the 
section CARDIOCARYON resembles Pterocarya. In addition, there is a simi- 
larity between the two taxa in the number of bracts, bracteoles, and 
sepals in both staminate and pistillate flowers (Manning, 1940, 1948). 
Thus evidence from a variety of lines suggests a close relationship between 
Juglans and Pterocarya and most particularly between Juglans section 
CARDIOCARYON and Pterocarya. 

Following this line of reasoning, it is suggested that the scatter diagram 
(Figure 108) depicts the evolutionary trends within the Juglans-Ptero- 
carya complex. The base of the sequence is occupied by the ‘“Ptero- 
caryoid” grain of relatively small size, low pore number, and high fre- 
quency of isopolarity. The “Cardiocaryoid” type can be derived from this 
by an increase in pollen size, pore number and heteropolarity. The evolu- 
tion of the ‘““Rhysocaryoid” type of grain from the latter simply involves 
an increase in pore number. From the “Rhysocaryoid” type there were 
apparently two independent evolutionary lines, the first involving an in- 
crease in pore number and culminating in Juglans nigra, the second involv- 
ing a stabilization of pore number and an increase in pollen size (culmi- 
nating in Juglans regia (§ Dioscaryon)). The relatively isolated position 
occupied by the tropical American species of section Ruysocaryon (J. 
olanchana, J. neotropica, J. insularis, J. australis) might suggest an early 
time of isolation from the main RuysocaryYON line, and the retention of 
relatively “primitive” characteristics (low pore number and small pollen 
size). 

The evolutionary trends outlined here are summarized graphically in 
FicurE 110. This is designed only to portray the evolution of pollen types, 
not necessarily the relationships of extant taxa. The two may well be 
parallel (as seems to be the case within the Juglans-Pterocarya complex), 
but obviously such phylogenetic speculations must involve a consideration 
of all data bearing upon the problem.

March 26, 1920. 

Please collect for us as many specimens as you can of the Azaleas which 
have passed as nudiflora. Apparently this species does not get into Loui- 
siana at all. The specimens which we collected at Winnfield April 6, 1913, 
Palmer’s 8882 and 9462 from Natchitoches, one specimen which we col- 
lected April 12, 1915, at Lakes Charles and one which I collected in 1885 
at Pineville belong to Azalea canescens. There appears to be a distinct 
form of this last in Mississippi, Louisiana and Texas differing in the gla- 
brous under surface of the leaves and more slender corollas. This is 
Palmer’s Natchitoches specimen 7228 and the plant with white flowers 
which we collected at Lake Charles April 2, 1913. So far as we know now 
this form always has white flowers, or nearly white flowers, and grows in 
swamps or on the borders of swamps. 

The specimens which I have enumerated are the only ones we have from 
Louisiana. I suspect that this new form, which will probably have to be 
treated as a variety of canescens, grows in eastern Louisiana as it seems to 
be common and the only form in southern Mississippi. We have specimens, 
however, of no early-flowering Azalea from eastern Louisiana. Please look 
out for this this spring as we are working here on a monograph of 
American species. The only Azalea from eastern Louisiana which we have 
is what has passed for Azalea viscosa. It is not that species which does not 
get south at all, but Small’s Azalea serrulata which grows from central 
Florida through southern Mississippi to eastern Louisiana. 

I wonder if we are going to live long enough to get the trees and shrubs 
from Louisiana properly straightened out. I hope you will do what you 
can in this Azalea business this spring and send us as much material from 
as many localities as possible.

April 8, 1920. 

I read in a Boston paper that Louisiana is to be hunted from end to end 
for a mysterious species of Aronia and for an Ash-tree, and that the New 
Orleans Garden Club has been called on by Harvard to perform this 
service, so I suppose great results can be expected. In the meantime I wish 
you would dry for me flowers of as many of the different Azaleas cultivated 
in the old Louisiana gardens as you can reach. We are making here a 


* Continued from volume 46, p. 361. 


412 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


systematic study of the Azaleas of eastern Asia which have been in a help- 
less state of confusion, especially cultivated plants, and we are interested 
to know if possible which were the Azaleas cultivated in the southern 
states. 

On the Butler place I made a couple of specimens which turned out to be 
Azalea ledifolia but there are probably other species cultivated. From the 
specimens we shall be able to name the species at least to which the plants 
belong. I should think that this would be a subject in which the members 
of your Garden Club would be interested; still if they want to hunt swamps 
for a missing Ash-tree I would not discourage them. 


241 
April 16, 1920. 

I have this morning your letter of April 12th. Do not forget that 
Crataegus silvicola Beadle grows in eastern Louisiana. Unfortunately I 
have had to change the name of drimophila because there is an older 
Crataegus silvicola published in Europe. 

It is much more than two years since I have heard from your lady 
friend in Crowley.2! She did send me some May Haws but I can hardly 
believe that I told her the May Haw had practically disappeared from 
western Louisiana where it seems to be more abundant than anywhere else. 

Is there any reason why Azaleas should not grow in New Orleans gar- 
dens? They certainly do well in West Feliciana Parish, at the Butler place 
and at Natchez. We are taking a good deal of interest in these plants now 
and are beginning to print a book about all the Azaleas in the world. I 
should like to send you some plants in the autumn for your friends if there 
is a chance of their doing well in Louisiana. Azaleas would certainly do 
well, I should say, in the Selma region. 

We are still having very bad weather and although the frost is all out of 
the ground spring is not making much headway. I noticed this morning 
that the buds of Dirca palustris were just beginning to open. 

Hope to hear from you soon. 


242 
May 27, 1920. 

The evergreen plant of which you send me a fragment is Cocculus 
laurifolius >? from southern China. The package with Azaleas, etc., was 
duly received. These appear to be all Rhododendron canescens but you 
will know more about them later. Rehder’s present theory is that nudi- 
florum is not a southern plant at all. 

I am horrified at what you write about Adelia fifty feet high and a tree. 
If your plant is really a tree how can it be kept out of my Manual? I 
have seen thousands of these Adelias in different parts of the country and 
growing under favorable conditions. They were never trees in the true 

sense of the word, that is with a single trunk, but really large shrubs.

1965] EWAN, LETTERS FROM SARGENT TO COCKS 413 


Please write me at once about your Baton Rouge specimen. If it is a tree 
what is the diameter of the trunk, and especially how tall is it before it 
begins to divide into branches? I hate the idea of putting Adelia in the 
Manual, but after the big specimens of Styrax we saw in West Feliciana 
Parish there is no knowing what may happen in western Louisiana. If 
Adelia is to be put in the Manual I ought to know about it at once. 

I had yesterday a very pleasant visit from your friend Miss King who 
talked to me a great deal about you and your success with your Garden 
Club and with the ladies of New Orleans generally. She was here only a 
short time and I was able to show her very little of the Arboretum which 
she seemed to enjoy. She agreed with me that you ought not to delay much 
longer the publication of your Flora. You of course cannot begin to print 
it until you have been here for consultation with various books, specimens, 
etc. There is no better time for you to do this work than this summer. 
I expect to be here all summer and to be living alone most of the time, so 
come and stay with me as soon as you like and work here and in Cam- 
bridge. Do not think about this but come. 


243 
June 11, 1920. 

I have yours of the 5th of June and read with regret what you say about 
the Adelia. How tall was the trunk with a diameter of eighteen inches, 
that is how soon did it begin to branch above the surface of the ground? 
Perhaps you can get some further information about the size of the plant 
on the Alabama River. I really don’t want to put this plant in the new 
Manual but I am afraid you will compel me to do so. I will write you about 
your Huckleberry as soon as the specimens are mounted. 

Your specimens of Aronia which you send me have leaves as large or 
perhaps even larger than the type of Hooker’s variety macrophylla, so 
I suppose if you want to include this variety in your Flora you have 
authority to do it. 

Please reconsider your assumed inability to come north this summer. 
You have to publish your Flora sometime and even if you should put off 
doing so for another fifty years it would not be complete when it was 
published. I do not believe it is wise to wait any longer, and you certainly 
cannot publish until you have come north to see various books. There is 
no time so good as this summer for doing this, and I think if you only 
stayed three or four weeks and worked hard you would do everything 
there was to be done here. At this end of the route there is every reason 
why you should come this summer and not put it off longer. It will be an 
awful pity if all the work you have done on the Louisiana flora was wasted, 
and it will be if your book is not published. Delays are fatal. 


244 

June 21, 1920. 

I have a bundle with two specimens of Azalea and a Prunus. I under- 
stand that the Prunus is the plant from which you sent, in a pasteboard 


414 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


box, a small quantity of fruit a few days ago. Am I right in this supposi- 

ion? I do not know this Plum at all but I trust you haven’t found a new 
species. The leaves look a good deal like those of P. angustifolia variety 
varians but the fruit, judging by the stone, can be no form of angustifolia. 
I should take the fruit for that of munsoniana which, however, does not 
ripen before the middle of August. As I understand it angustifolia ripens 
in Alabama by the Ist of May and the fruit of this new plant does not 
ripen much before the middle of June and much earlier than munsoniana 
which also grows in the Selma region. 

We have in the herbarium here your Nos. vii. 1913; 15 and 16 of 1914, 
and 896 of 1914. These are placed under P. munsoniana. Do any of these 
numbers belong to the new tree and, if not, have you flowers to accompany 
the leaves and fruit sent this year? We have also Nos. 1 and 3, March 
1914 which are probably P. munsoniana. As I understand the new tree 
does not sucker. Is it common and how large does it grow? I cannot bear 
the thought of another Plum tree. 

Please answer this letter by return mail and tell me everything you 
know about “Prunus Cocksii,” of which I hope there is but a single plant, 
in which case I won't feel like doing anything about it. 


245 
August 3, 1920. 

I am struggling to arrange the Prunus material in this herbarium and to 
write up the genus for the Manual. The only thing I have really accom- 
plished is to convince myself that I know nothing whatever about American 
Plum-trees. I have, however, made the following notes for you 

Alabama. Yellow fruit, August 20, 1918, is probably P. umbellata. Your 
leaf specimen sent in October of that year is very poor. Please press and 
send us others as soon as possible. Notice that the leaves are much more 
pubescent than those of the ordinary form of P. wmbellata. This has always 
made me hesitate about this specimen. 

Prunus, June 15, 1920, I suppose we must call angustifolia varians 
until we know something more about it. Please send us more herbarium 
material with well grown leaves. If this determination is correct the plants 
must be an escape from cultivation. I do not understand your fruit “in 
long racemes.” Prunus never has racemose fruit. 

Pine Flat near creek, No. 892. We have fruit but do not find leaf 
specimens. Please send these if you can find the tree. 

You do not appear to have collected Prunus americana in the Selma 
district although Harbison found it there and we have several specimens 
from him. 

Eastern Louisiana. The following I refer to Prunus lanata. 1 and 2, 
Butler Plantation, March 28, 1910. 20, West Feliciana, October 1914. 
Covington, March 28, 1911. Open woods, Hammond, May 13, 1910. 
Laurel Hill, Nos. 2 and 3, October 7, 1910. Ventries Plantation, April Zi, 
1910, Prunus No. 2, Butler Plantation, “Clover Hill, 200 feet west of 
pond,” March 28.

Western Louisiana. Lanata, Palmer, Nos. 7015, 80677{sic], 7069, 
8859, 7074, 7051, 8742, 7008, 8789. 

To Prunus mexicana I refer Laurel Hill No. 4, October 7, 1910; Pine- 
ville, Cocks, September 20, 1912, a tree fifteen miles west of Opelousas, 
C.S.S., October 10, 1913; Ruston, Cocks, No. 6, August 24, 1914; Archi- 
bald, Cocks, No. 18, October 1910; Alto, Cocks, No. 14, October 1910. 
We have Cocks’ numbers 1 and 2 Vinton, April 3, 1912, flowers only. 
Can you complete these? 

The specimen we collected on the Gentilly Road below New Orleans 
April 15, 1915, seems to be Prunus americana, the only specimen of this 
species which I have seen from Louisiana. This should be followed up 
and mature leaves and fruit collected. 

Does not Prunus caroliniana grow in western Louisiana? It does in 
eastern Louisiana and is very common indeed in eastern Texas. We have 
nothing here, however, to show that it grows in western Louisiana. Our 
only specimen from Louisiana is from West Feliciana. I should suppose 
that it would grow in the neighborhood of Hammond and in other places 
nearer the coast. I should like to know about this. 

Cocks’s No. 7, Sardis, received July 19, 1913, with large slightly pubes- 
cent leaves which might be those of P. americana, and small globose fruit. 
If this fruit and leaves belong to the same plant I do not know it. Can you 
do anything about this? 

No. 9, Sardis, July 1913. I have placed this with P. Janata. Harbison’s 
No. 101, Selma, September 20, 1919, is the same. I enclose a leaf of your 
No. 9. Your No. 9 and Harbison’s No. 101 are the only specimens of this 
species from Alabama which I have seen and they probably represent its 
most eastern range. I hope you will investigate your No. 9 further and get 
more material. I should like to know if it is common in the region. 


246 
August 7, 1920. 
I find in the Gray Herbarium a specimen of Prunus caroliniana collected 
by Drummond in New Orleans which of course may mean Covington. 
There is also a Hale’s specimen in the Gray Herbarium without locality, 
and a specimen from Ocean Springs, Mississippi, collected by Tracy. 


247 

September 7, 1920. 
Dr. Robert Ridgway, the distinguished ornithologist, has established a 
sort of bird haven on a piece of land with a area of eighteen acres near 
Olney, Illinois. He claims that there are sixty-four native trees growing on 
these eighteen acres. This of course is a very large number, but I should 
not be surprised if there were even more species growing, perhaps not on 
eighteen acres but within a radius of eight or ten miles of Selma. Can you 
make out a list of the Selma trees? It would be interesting to publish this 

in connection with Dr. Ridgway’s list. 


416 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


If you are in North Carolina I am sure you are enjoying yourself there. 
As I do not know your address I am sending this to New Orleans in the 
hope that it will reach you sooner or later. 


248 
Sept. 27, 1920. 
I find no specimen of Zanthoxylum clava-herculis from eastern Louisiana 
in this herbarium. I suppose it grows there and that you have a specimen 
for us. 


249 
November 2, 1920. 

There are two or three very fine Formosa conifers which we can send to 
you if you can find some one in New Orleans to take care of them. As they 
grow at a considerable altitude in Formosa there is a chance that they may 
prove hardy in Louisiana. Among them will be the Taiwania which is 
one of the great trees of the world. We can send you a few young plants of 
the Ogechee Lime, Nyssa Ogechee, which I do not suppose any one has 
cultivated before. It is worth growing for the beauty of the fruit. Also a 
Formosa oak. 

I do not know what sort of a permit will be needed in order to send 
these plants into Louisiana. If one is needed will you get it from the proper 
authorities and send it to me? As these are all tender plants they ought to 
be started from here before it gets too cold. 


250 

November 4, 1920. 
Do you remember the Persimmon trees which we saw on the Moon 
Plantation in Richland Parish? Some of the trees were growing in water 
and others on dry land. These trees had broad often cordate leaves very 
pubescent on the lower surface. You sent fruit of these but we foolishly 
allowed it to dry instead of putting it in formalin and it is not possible 
now to form an idea of the shape. Do you remember if it was broader than 
high and flattened at the ends? We have a specimen of Persimmon col- 
lected by you in swamps near New Orleans with cordate leaves pubescent 
below. Would it be possible to get some fruits from a tree growing in the 
New Orleans swamps? I am anxious to see the size and shape of the swamp 
Persimmon which seems to me to represent a pretty distinct variety of 
Diospyros virginiana. It is possible that the fruit is still on the trees; 
if not, it is perhaps on the ground underneath them. I find, with the 
exception of this from New Orleans, we have no Persimmon specimen from 

eastern Louisiana. 


251 
November 10, 1920. 
We have no specimen of Euonymus atropurpureus from Alabama or 
Louisiana. I should suspect, however, that it would grow in Dallas County, 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 417 


Alabama, as everything else seems to grow there and I should also expect 
it in western Louisiana as it is in eastern Texas and southern Arkansas. 
I shall be glad of any light you can give me on this. 


252 
November 16, 1920. 

I enclose a list of plants which are going to you by parcel post. The 
Chamaecyparis is an immense tree in Formosa and I hope it may prove 
hardy in Louisiana. The Cunninghamia is a new species from Formosa for 
which the Louisiana climate may be too cold. Juniperus taxifolia is a very 
fine Juniper from the Bonin Islands which has not before been cultivated. 
The Quercus is an evergreen species from Formosa. The Picea and Pinus 
are also Formosa plants. 

The Taiwanias are the most interesting trees in this collection and I hope 
they will succeed in Louisiana. Will you send one of them to our friends at 
Avery Island? 

You had best keep for your own garden the Torreya which is the Florida 
species and certainly ought to do well with you, and the Gordonia. Nyssa 
Ogechee is a very handsome tree which I do not think has ever been 
cultivated before and which I should think would succeed in any part of 
Louisiana. We have several more plants of this to dispose of and if you 
would like to have them and will send us another permit you shall have 
them. 

I am delighted to hear that you are going to have a garden at Bay St. 
Louis and I think we shall be able to send you from time to time many 
plants for it. 


253 

November 26, 1920. 
In this herbarium there is no Louisiana specimen of Acer saccharinum 
although some of the books say that it grows in Louisiana. It does not 
seem to be very rare in south central Mississippi and there would not seem 
to be any reason why it should not occur in eastern Louisiana. As it grows 
in southern Arkansas it would not surprise me to hear that it grows all 
over the state. We certainly should have specimens of it. According to 
Mohr it grows all over Alabama but we have no Alabama specimen, not 

even from Sardis! Help needed. 


254 

December 27, 1920. 
I am much obliged for the specimen of the Silver Maple from the neigh- 
borhood of Alexandria. This is the only evidence I have that this tree

I had not supposed was found nearer Louisiana than the high mountains 

of North Carolina.

Did you know that Drummond found what we now call Rhododendron 
serrulatum in Louisiana? One of his specimens in the Gray Herbarium is 
labeled New Orleans. In Hooker’s list of Drummond’s Louisiana plants 
Covington is given as the station. This you know is the plant you found 
near Pearl River, and this is the only station we know for it in Louisiana 
unless you have found it in Covington or its vicinity. It might well be 
found in swamps anywhere in the coast region of eastern Louisiana. This 
and Rhododendron canescens are the only species we know in Louisiana. 
It would not surprise me, however, if you should find Rhododendron 
oblongifolium somewhere in the neighborhood of the Sabine River. This 
species is not rare in southern Arkansas and grows near Marshall and 
Houston in eastern Texas. I should think it would be worth looking for as 
another addition to the Louisiana flora. 

With all good wishes for the New Year, I am,

Ulmus americana flowered in Vermont April 19th, in Massachusetts, 
April 15-20. From Ohio, Florida and Arkansas there is no flowering

Salix nigra: Massachusetts, May 20-26; Ohio, May 8; Arkansas, April

Acer rubrum: Vermont, April 23; Massachusetts, April 8-21; Ohio,

and not dated; Arkansas, no flowering specimen. 

This is in reply to your note of January 3rd. I do not know why you 
have asked for this information unless it was to expose the weakness of 
this herbarium. 

There isn’t much more, I fancy, for us to find out about Louisiana trees, 
so why don’t you prepare a list of them with short notes on their distribu- 
tion and habitat and we will publish it in the Arboretum Journal if it is not 
too long? This will make a good start on your catalogue of Louisiana 
plants.

In this herbarium there is only one specimen of Bumelia lycioides and 
that was collected by you at Wakefield in West Feliciana Parish where you 
say on the label it is common. Do you know it from other parts of the 
state? I should expect it at Lake Charles and in other parts of West 

Louisiana as it gets into the coast region of eastern Texas. 
I shall be obliged for any further light you can send me on this subject.

in the time of flowering for the outside world does not know very much 
about the behavior of trees in Louisiana. I think there should be informa- 
tion of the frequency of the different species in different parts of the state 
and their places of growth. I suppose you have all the information. 

In this herbarium there is no Halesia from Louisiana but diptera. Have 
you ever found anything else from within the state? Carolina appears to 
be common at Selma but there is nothing here from further west.

Your Ligustrum is lucidum as you suppose. Sometime ago I wrote you 
that I thought a specimen of Fraxinus collected at New Orleans by Fendler 
in 1846 might be F. pauciflora. I now feel convinced, however, that it is 
F. americana. The handsomest trees of Fraxinus americana 1 have ever 
seen are those below Lake Charles along the river, the trees with slender 
pendulous branches and narrow leaves. We collected it in early spring. 
Have you ever collected fruit or mature leaves from these trees? They 
ought to be distinguished as a variety perhaps but I do not like to do it 
without better material. If you have never obtained fruit or mature leaves 
you ought to try and get them sometime in the future. This is certainly one 

of the handsomest of the Louisiana trees. 


259 
March 3, 1921. 
If there were any specimens of Viburnums in the package with the 
Ligustrum they were overlooked in the unpacking. If you send others we 
shall hope to be more careful. 
It looks like an early spring here but cold weather is predicted again 
and New England springs are not to be relied on.

March 14, 1921. 
Of Cephalanthus occidentalis we have two Louisiana specimens in this 
herbarium, one collected by Palmer near Natchitoches and another in the 
neighborhood of Lake Charles by some collector I do not know. These are 
both the pubescent form, the var. pubescens of Rafinesque. We have no 
specimen here collected by you, and nothing whatever from east Louisiana 
where I suppose it is common; nor have we any specimen from the Selma 
region where I should be surprised if it were not common. I should be glad 

of more Louisiana material. 


261 
March 21, 1921. 
Your Viburnum is, as you thought, odoratissimum. The Blackberry is 
Rubus rosaefolius var. coronarius, the double-flowered form of the widely 
distributed Asiatic species. I am glad to know that this double-flowered 


420 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


form is in cultivation in the United States and I wish you would dry 
flowering specimens for this herbarium where there is nothing to show 
that it is cultivated in this country. 

The thermometer was up to 78 yesterday which means there will be a lot 
of damage done by frosts which are sure to come in the course of a week 
or two. 


262 
March 28, 1921. 

I like your catalogue very much and am glad to get it. I see you include 
among the trees Jlex lucida, Rhus glabra and Sambucus canadensis which 
are not in the new Manual, probably by mistake. You omit Aesculus Pavia 
which certainly grows in east Louisiana where we saw the best specimen 
I have ever seen. Vaccinium arboreum var. glaucescens which grows about 
Shreveport is also omitted. I do not think there is any Viburnum pruni- 
folium in Louisiana where Viburnum rufidulum, not in your catalogue, is 
common. 

I am inclined to refer to Acer saccharum var. glaucescens your St. 
Francisville specimen 2520, May 15, 1915, my Des[s]ert Plantation, April 
12, 1916, your Catalpa specimen 3170, April 15, 1919, and Palmer’s 
Natchitoches specimen 7400, April 27, 1915. Acer saccharum var. glau- 
cescens sometimes looks too much like Acer floridanum. Indeed all the 
Sugar Maples run together, and if there were not so many distinct varieties 
and forms it would be wise to consider them all as belonging to one species, 
but this would be very cumbersome in a book and hard to use. 

I should like to know the exact range of Avicennia in Louisiana. We 
have no specimens from the state and should be glad to have them. I had 
supposed it was on some of the islands and not on the mainland. There is 
time to make corrections in this for the Manual. 

A few of your names are not the ones we now use. I suppose you won't 
object to having your list similar to the Manual in this respect. Unless 
you object I will make the corrections and additions, and have the article 
set up and submit the proof to you. 

We are having a very early season here and many things are blooming 
at least three weeks ahead of time. The severe frost which we are likely to 
get in April will do a greal deal of harm I fear. 


263 

April 4, 1921. 
Your Ligustrum seems exactly like the one we gathered early one morn- 
ing on the campus at the University at Baton Rouge. At the time that 
specimen was referred to L. coriaceum, but the leaves are too thin and it 
seems best to consider that plant and yours received today L. japonicum 
in spite of the fact that the leaves of japonicum are more inclined to be 

acute. 
I notice in your list of Louisiana trees you do not say anything about

Sapindus Drummondii from Tangipahoa, your No. 71 collected in June 
1900. It is certainly that species and interesting as the only evidence we 
have here that Sapindus Drummondii grows east of the Mississippi River. 

In the description of Bumelia lanuginosa I have adopted your statement 
that on the Louisiana seacoast, near the mouth of the Calcasieu River, it 
grows on the sandy beach as a shrub, forming dense thickets in a position 
where it is often covered by ocean spray. We have no specimen from this 
coast but I suppose there is no doubt of the species. We should like a 
specimen from there if you can spare it. Let me know at once if for any 
reason the statement should be eliminated from the Manual. 


264 
April 18, 1921. 

I have been over your list of trees and sent it to the printer. You can 
expect a proof in the course of a couple of weeks or so. 

You speak of Malus coronaria in East Louisiana. This of course is 
Malus angustifolia which also occurs in a rather pubescent form near 
Winnfield. 

You speak of Aesculus Pavia as growing over the state. Is not this a 
mistake? My opinion is that it is confined to east Louisiana and that it 
nowhere crosses the Mississippi River. West of the river, so far as our 
collections here show, the red-flowered Aesculus is all discolor var. mollis. 

You speak of Oxydendrum as growing in rolling woods over the state. 
Is not this a mistake? We have nothing to show here that it is in Louisiana 
outside of West Feliciana Parish where I think, like Magnolia Fraseri, it 
must find its southwestern home. If I am wrong about this and it does 
occur west of the Mississippi River please let me know by return mail as 
there is still time to make the correction in the Manual. 

Is it possible that the Osage Orange may grow naturally in the extreme 
northwestern corner of the state. Have you ever fully investigated that 
region? Elsewhere in the state I feel sure that it must be naturalized. 


265 
August 7, 1921. 

We have included your Washington Parish Myrica in the list of trees, 
for although there is no fruit it is evidently Myrica inodora. Although 
it grows as a shrub in Louisiana it is sometimes a small tree, and therefore 
properly finds a place in this list. It Wes asi interesting to find other 
stations and obtain if possible fruiting specim 

By all means let us publish the list of ee shrubs and the sooner 
you get to work the better. I fancy it will be a harder task than the trees 
but it can be accomplished I think. 

I haven’t the slightest idea what “‘auto-intoxication”’ means. It does not 
sound like the right kind however. What you need is a change of air and 
scene, and why you don’t come up here and pass a month or two with me 
this autumn I cannot imagine. The sea voyage would do you a lot of 
good and you would have the opportunity to work here on your Flora.

If you are in North Carolina I am sure you are enjoying yourself there. 
As I do not know your address I am sending this to New Orleans in the 
hope that it will reach you sooner or later. 


248 
Sept. 27, 1920. 
I find no specimen of Zanthoxylum clava-herculis from eastern Louisiana 
in this herbarium. I suppose it grows there and that you have a specimen 
for us. 


249 
November 2, 1920. 

There are two or three very fine Formosa conifers which we can send to 
you if you can find some one in New Orleans to take care of them. As they 
grow at a considerable altitude in Formosa there is a chance that they may 
prove hardy in Louisiana. Among them will be the Taiwania which is 
one of the great trees of the world. We can send you a few young plants of 
the Ogechee Lime, Nyssa Ogechee, which I do not suppose any one has 
cultivated before. It is worth growing for the beauty of the fruit. Also a 
Formosa oak. 

I do not know what sort of a permit will be needed in order to send 
these plants into Louisiana. If one is needed will you get it from the proper 
authorities and send it to me? As these are all tender plants they ought to 
be started from here before it gets too cold. 


250 

November 4, 1920. 
Do you remember the Persimmon trees which we saw on the Moon 
Plantation in Richland Parish? Some of the trees were growing in water 
and others on dry land. These trees had broad often cordate leaves very 
pubescent on the lower surface. You sent fruit of these but we foolishly 
allowed it to dry instead of putting it in formalin and it is not possible 
now to form an idea of the shape. Do you remember if it was broader than 
high and flattened at the ends? We have a specimen of Persimmon col- 
lected by you in swamps near New Orleans with cordate leaves pubescent 
below. Would it be possible to get some fruits from a tree growing in the 
New Orleans swamps? I am anxious to see the size and shape of the swamp 
Persimmon which seems to me to represent a pretty distinct variety of 
Diospyros virginiana. It is possible that the fruit is still on the trees; 
if not, it is perhaps on the ground underneath them. I find, with the 
exception of this from New Orleans, we have no Persimmon specimen from 

eastern Louisiana. 


251 
November 10, 1920. 
We have no specimen of Euonymus atropurpureus from Alabama or 
Louisiana. I should suspect, however, that it would grow in Dallas County, 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 417 


Alabama, as everything else seems to grow there and I should also expect 
it in western Louisiana as it is in eastern Texas and southern Arkansas. 
I shall be glad of any light you can give me on this. 


252 
November 16, 1920. 

I enclose a list of plants which are going to you by parcel post. The 
Chamaecyparis is an immense tree in Formosa and I hope it may prove 
hardy in Louisiana. The Cunninghamia is a new species from Formosa for 
which the Louisiana climate may be too cold. Juniperus taxifolia is a very 
fine Juniper from the Bonin Islands which has not before been cultivated. 
The Quercus is an evergreen species from Formosa. The Picea and Pinus 
are also Formosa plants. 

The Taiwanias are the most interesting trees in this collection and I hope 
they will succeed in Louisiana. Will you send one of them to our friends at 
Avery Island? 

You had best keep for your own garden the Torreya which is the Florida 
species and certainly ought to do well with you, and the Gordonia. Nyssa 
Ogechee is a very handsome tree which I do not think has ever been 
cultivated before and which I should think would succeed in any part of 
Louisiana. We have several more plants of this to dispose of and if you 
would like to have them and will send us another permit you shall have 
them. 

I am delighted to hear that you are going to have a garden at Bay St. 
Louis and I think we shall be able to send you from time to time many 
plants for it. 


253 

November 26, 1920. 
In this herbarium there is no Louisiana specimen of Acer saccharinum 
although some of the books say that it grows in Louisiana. It does not 
seem to be very rare in south central Mississippi and there would not seem 
to be any reason why it should not occur in eastern Louisiana. As it grows 
in southern Arkansas it would not surprise me to hear that it grows all 
over the state. We certainly should have specimens of it. According to 
Mohr it grows all over Alabama but we have no Alabama specimen, not 

even from Sardis! Help needed. 


254 

December 27, 1920. 
I am much obliged for the specimen of the Silver Maple from the neigh- 
borhood of Alexandria. This is the only evidence I have that this tree 
occurs in Louisiana. I am surprised to hear that your [alleged] Xanthoxy- 
lum grows all over Louisiana as your specimen is a Sorbus americana which 
I had not supposed was found nearer Louisiana than the high mountains 

of North Carolina.

Did you know that Drummond found what we now call Rhododendron 
serrulatum in Louisiana? One of his specimens in the Gray Herbarium is 
labeled New Orleans. In Hooker’s list of Drummond’s Louisiana plants 
Covington is given as the station. This you know is the plant you found 
near Pearl River, and this is the only station we know for it in Louisiana 
unless you have found it in Covington or its vicinity. It might well be 
found in swamps anywhere in the coast region of eastern Louisiana. This 
and Rhododendron canescens are the only species we know in Louisiana. 
It would not surprise me, however, if you should find Rhododendron 
oblongifolium somewhere in the neighborhood of the Sabine River. This 
species is not rare in southern Arkansas and grows near Marshall and 
Houston in eastern Texas. I should think it would be worth looking for as 
another addition to the Louisiana flora. 

With all good wishes for the New Year, I am,

Ulmus americana flowered in Vermont April 19th, in Massachusetts, 
April 15-20. From Ohio, Florida and Arkansas there is no flowering 
specimen in this herbarium. 

Salix nigra: Massachusetts, May 20-26; Ohio, May 8; Arkansas, April 
8-22; Florida, March 24. No flowering specimen here from Vermont. 

Acer rubrum: Vermont, April 23; Massachusetts, April 8-21; Ohio, 
March 27; Florida, only one specimen in flower here collected by Chapman 
and not dated; Arkansas, no flowering specimen. 

This is in reply to your note of January 3rd. I do not know why you 
have asked for this information unless it was to expose the weakness of 
this herbarium. 

There isn’t much more, I fancy, for us to find out about Louisiana trees, 
so why don’t you prepare a list of them with short notes on their distribu- 
tion and habitat and we will publish it in the Arboretum Journal if it is not 
too long? This will make a good start on your catalogue of Louisiana 
plants.

In this herbarium there is only one specimen of Bumelia lycioides and 
that was collected by you at Wakefield in West Feliciana Parish where you 
say on the label it is common, Do you know it from other parts of the 
state? I should expect it at Lake Charles and in other parts of West 

Louisiana as it gets into the coast region of eastern Texas. 
I shall be obliged for any further light you can send me on this subject.

Palmer is here and he and I have been carefully over your unplaced 
Crataegus material with the following results. 

Palmer, Natchitoches, 9454, 8894, 8899, 7289, 7226 = C. velutina. 

Crataegus species, low woods, West Lake Charles, C. S. S., March 23, 
1917, = C. pyracanthoides, only known before from Mariana, Florida. 
I hope you will get fruit of this this autumn. 

Bush, Minden, August 10, 1901, C. S. S., April 10, 1901, is C. algens. 
This is your No. 1008 of 1916. 

Cocks, Crowley, 3326, 3327, April 14, 1920, C. berberifolia. 

Natchitoches, Cocks, No. 20, April and September 1914, C.Cocksit. 

Cocks, Crowley, 3331, C. viridis. 

Cocks, Crowley, 3324, 3337, 3329, 3328, 3330, 3325, and Natchitoches 
39, xii., xiii., xvi., is C. edura. 

Palmer, Natchitoches, 7290 and 8722 seem to agree with C. torva which 
you have at Sardis. 

This only leaves undetermined Bogulusa 3149, probably a new species 
of Intricatae and interesting as the only representative of that group from 
Louisiana. Fruit of this is needed. Can you get it this autumn? 

Crus-galli species, Cocks, Pineville, xix., April 24,— Fruit of this is 
needed. 

Pineville, Crus-galli species, April 5, 1912. Color of the anthers and 
fruit needed. 

Viridis species with rose-colored anthers. A large tree in yard below 
Lake Charles collected by you and me April 21, 1907. Fruiting specimens 
with terminal shoots are needed. 

Can’t you clean these up as far as possible this autumn? Certainly 
there are now fewer undetermined species and specimens of Crataegus 
in Louisiana than in any other state. Of course there may be other species 
in the state which you haven’t found yet but I do not believe there are 
many of them. 

The proof of your article hasn’t turned up yet, which is perhaps fortunate 
as the delay will enable me to insert these newly determined species in 
your list. 

I hope you are well and getting through the summer comfortably.

We have been looking over some of the Selma material and find a 
specimen of Crataegus interior Beadle, Harbison’s No. 3, “along road to 
Professor Cocks’s place, April 19, 1915.” 

Cocks 3242, Sardis, new species of Bracteatae. This is a very distinct 
and interesting looking plant in a small group with only two described 
species. I hope you can get fruit so that it can be named. To me this 
seems to be the most interesting of the Sardis species.

probably C. ‘aabamensis but we have no fruit. 

Harbison, Sardis 1468, April 23, 1914, seems to be C. ignava but fruit 
is needed. 

Cocks 831 and 834 may be C. lacrimata Small, but fruit is needed. As 
I have seen this species in Florida the branches are very pendulous. Is it 
so with your numbers?

Your Rosa humilis, Natchitoches, July and October, 1913, and Palmer, 
Creston, 9428, April 18, 1918, with pubescent leaves is now called R. 
Lyonii Pursh. This species, if it is one, is widely distributed from Massa- 
chusetts to Missouri and Louisiana. 

I wish this autumn you would send me for planting about a pint each 
of the nuts of Carya leiodermis and of C. leiodermis var. callicoma. As 
Carya myristiciformis seems to be hardy there is no reason why this other 
southern species might not be, and unless you get the nuts I do not suppose 
there is any one else now who could find the trees.

You have at last got page proofs of your acct of trees & I hope that 
it will now soon be published. 

I have added Avery Island as a station for the Dahoon (Jlex cassine). 
We saw it by the lake with ripe fruit. I evidently failed to take a specimen 
& I suppose that you did as you do not mention it. 

We have no La. specimen of this species in this herb. Can you let us 
have one. 

I hope that you are all right again. 

How about the shrubs? We are ready for them. 


270 
October 28, 1921. 
I do not see any objection to your including in your list of shrubs those 
which are occasionally trees and which have appeared in the previous list. 
I suppose you will let us have a specimen of J/ex and Amelanchier. 
Sorry to hear the Crataeguses have been behaving so badly this year. 
It certainly takes time and patience to get these things. 


271 
November 28, 1921. 
I have at last found time to look over your last sending of specimens. 
5001 can only be Fraxinus americana with unusually large fruit and 
with an obtuse wing. 


424 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


5003 is Viburnum scabrellum. 

5004 is Ilex longipes of Chapman. You collected the same thing in 
flower in the same locality and in several other places in the state where it 
appears to be common east of the Mississippi. 

Ilex amelanchier is a good find for Louisiana. It is not very rare in 
Alabama but I have seen no specimen in Mississippi. 


272 
December 5, 1921. 

Your list of Louisiana trees is in the April number of the Journal of the 
Arboretum which, owing to a printers’ strike, has not yet appeared, al- 
though we have seen it in page-proof. This strike is very annoying. It has 
entirely demoralized the issues of the Journal, but the Manual is now 
promised for the middle of January. 

Fraxinus Darlingtonii and Fraxinus Smallii exist only in the fertile 
brain of Dr. Britton. 

With the compliments of the season,

Palmer’s Rubus 7431 is referred in the Flora of North America, which 
is published by the New York Botanic Garden, to carpinifolius Rydberg. 
The type of this species was collected near Alexandria. Palmer’s 7208 is in 
the same work called R. floridus Rydberg. How good these species are 
you can judge as well as I can. 

There are a number of distinct forms of Rhus toxicodendron in your 
part of the world and it was one of these which we collected at Shreveport. 
Nothing has ever been done in the way of separating this species into 
varieties but it certainly ought to be done. We have a large collection of 
them in the herbarium here. 

The proper name of the Ptelea which we collected at Lake Charles is 
P. trifoliata variety mollis Torrey & Gray. 

It seems a hard proposition to try and get any of Palmer’s specimens 
from St. Louis for you. Palmer has talked about it several times and I have 
written. Palmer, who is working here this winter, will be in St. Louis in 
March and in half a day could pick out a set of herbaceous plants for you 
if he was permitted to do so, I do not know if this could be managed but 
it will do no harm to try. You certainly ought to have the plants and we 
made a mistake not to have asked Palmer to collect a special set for you 
and send them direct. I understand you have all the numbers of Palmer’s 
woody plants. 

With the compliments of the season, I am,

Palmer’s 9428 is a Rose. His Vaccinium tenellum number is 9429. 


— oe 





1965 | EWAN, LETTERS FROM SARGENT TO COCKS 425 


This number and his 9411 and 9469 we think are Vaccinium vegetum. 
We have no V. corymbosum from Louisiana, although it is said to grow 
there by Small. He also credits V. fuscatum, which is V. corymbosum var. 
fuscatum Gray, to Louisiana. We have one specimen of this from Texas. 
It only varies from corymbosum by the pubescent under surface of the 
leaves and by the pubescent branchlets. This variety grows in southern 
Georgia, and as it grows in Texas it might be expected in Louisiana, al- 
though we have no specimen from either Alabama or Mississippi. From 
Louisiana we have only one specimen of V. tenellum, your 4333 from Bayou 
Lacombe. We have no specimen of Vaccinium myrsinites from Louisiana. 

It looks as if there was still a great deal of Vaccinium work to do in 
your state. 

With all good wishes for the New Year, 


275 
January 11, 1922. 

I have your package of Vacciniums. 

3343, Fulton ?, is apparently V. corymbosum. All the others, Benton 
3210 and 3207, Covington 1504, and Natchitoches 3202 are V. virgatum 
according to our understanding of that species. 

I am glad to hear you are moving to Bay St. Louis which I am sure you 
will enjoy much more than New Orleans, and that you will have the 
opportunity for a good garden. In the spring we can contribute to it, if you 
say so, some Azalea and Camellia plants and possibly a few other things. 


276 
January 13, 1922. 

Your Crataegus 966 and 3342 of September 19, 1915, and April 20, 
1916, has twenty stamens. This seems a distinct and handsome new 
species of the Bracteatae group of which only two species have been 
described. The color of the anthers is not given. Can you get notes on 
them this spring or, if that is not possible, can you tell Harbison where 
this tree is growing? This is certainly your best Crataegus discovery and 
I am sorry Crataegus Cocksii is preoccupied. Will you suggest a name for 
it? 

No. 7, Harbison, April 20, 1915, from the Sumner region we are referring 
to C. blan da. 

Your Jasmine is the double-flowered form of J[asminum]| Sambac.?* 
This plant is widely cultivated in warm countries but I have not before 
seen specimens from the United States except from San Diego, California. 
It is of doubtful origin as to country and I think only the double-flowered 
form is known.

for = ied Bee in 1776 and Lelievrie, fer New Orleans in 1838, but without

Glad to hear about the color of the anthers of 3342. We have, I think 
abundant material of this with the exception of seeds which should be 
collected for planting. I hope you will invent a good name for it. Better 
send us a specimen of the plant which you have been calling Jasminum 
Sambac and perhaps we can help you. Certainly what you sent before is 
the Sambac. 

My variety of Quercus coccinea with thickened cup-scales was based on 
plants from your place in Alabama. This was stated in my paper on 
Quercus in The Botanical Gazette, and if it were not easy to make mis- 
takes I should be at a loss to understand why this fact was not brought 
out in the Manual. 

So far as I have observed all the Scarlet Oaks in the Selma region which 
I saw had these thickened cup-scales. 

Another mistake which has been pointed out to me is that Small and 
not Ashe is the authority for Tilia floridana, and I am feeling rather 
disgusted. 


278 
February 6, 1922. 

I am describing Palmer’s Crataegus 7234 and 8843, April and October 
1915, from Natchitoches as C. erioclada and his 3719, September 1915, 
as C. brachyacantha forma leioclada. 

The copy of the Journal with the Louisiana list of trees has arrived here 
this morning and I hope you will soon get your extras of the article. When 
you do I wish you would let us have one so that we can have it in this 
library as a separate. 


279 
February 17, 1922. 
Crataegus erioclada is a new species, a description of which will appear 
in the next number of the Journal I hope. 
I have no doubt there is a lot of collecting to be done along the Missis- 
sippi coast. I am glad to hear you are to undertake it. 


280 
March 1, 1922. 
The omission of O[uercus| virginiana might have got by you but I can- 
not imagine how it got by us here where the article and proof was certainly 
read times enough to prevent any such glaring omission. I think the best 
plan would be to add a note to your list of Louisiana shrubs making the 
correction. It would be more apt to be noticed there than if put by itself in 
the Journal. 
How is the list of shrubs getting on[?]

April 21, 1922. 

We were getting ready to send you next week the Camellias and other 
plants for your new garden when we discovered that it was necessary to get 
a permit from the Horticultural Inspector of Mississippi, and I am writing 
him today for one. This means I suppose that the sending of the plants 
will be delayed for at least a couple of weeks. It won’t do any harm if you 
wrote to the Inspector yourself on the subject in the hope of hurrying him 
up. 

You haven’t suggested yet the name for that fine and very distinct 
Crataegus of yours from Selma 

We have a late spring here this year and last night had rather a heavy 
frost, but on the whole the Arboretum looks fairly well. 


282 
May 9, 1922. 

I have now the permit from Mississippi to send you the plants for your 
garden and they shall go forward in the course of a day or two. 

There is no specimen of Calycanthus in this herbarium from Louisiana 
or Mississippi and I did not know it extended as far westward. By all 
means send me all the material you can of your two species for this is now 
one of the genera we are especially interested in as there seems to be great 
confusion in the cultivated plants. For example, Calycanthus floridus 
which is supposed to be in every garden we cannot find cultivated any- 
where in this country except in the Berckmans Nursery in Georgia where 
the yellow-flowered form is growing. In Alabama we know Calycanthus 
floridus only from Spring Hill near Mobile, Lookout Mountain, near 
Gadsden, and at Barclay. I am surprised it does not grow at Selma. 
Perhaps you will find it there. 

Ow are you getting on with the catalogue of shrubs and aren’t you 
coming up this summer to work here on your general catalogue? You 
certainly never can complete it without passing some time at the north, 
and what is the use of delaying your coming any longer? 


283 
May 23, 1922. 
Your two specimens of Calycanthus seem to be the same, although the 
specimen from Bay St. Louis has remarkably narrow sepals. They appear 
to be forms of fertilis manus and if this determination is correct it is re- 
markable to find them on the Gulf coast, for fertilis nanus has previously 
been known only from the mountains of North Carolina. I should have 
expected that you would have found in your region - Sy ie which 
grows in the neighborhood of Mobile and is a southern s spec 
You ought to look further for Calycanthus for it is aonite that you 
have other forms or species. It would be well to get fruiting specimens 
of the two plants of which you have sent the flowers. 


428 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


I noticed that Small does not credit any Calycanthus to either Missis- 
sippi or Louisiana. 


284 
May 26, 1922. 

I am interested in what you say about Calycanthus floridus in Louisiana 
and I hope we shall get a specimen of it from the state. I shall be glad, 
too, of one from the Selma region. There are two forms of floridus, one 
with much broader leaves than the other, and I am anxious to know 
which is the form which grows in Louisiana. 

We have at last dispatched your plants to Bay St. Louis and I enclose a 
list of them. Rhododendron Chapmanii is not a plant with very showy 
flowers, but it is an interesting species found only close to the Gulf coast of 
west Florida. We had a many years’ hunt for this plant which was origi- 
nally discovered by Chapman and described by Gray. It should grow 
perfectly at Bay St. Louis. 

I hope the Juniperus taxifolia will grow. It is a native of the Loochoo 
Islands and has not before been cultivated. There is a good chance, how- 
ever, that it will prove hardy in Bay St. Louis. 

There isn’t much to say about the other plants which are going to you. 


285 
June 28, 1922. 

We have received the list of Louisiana shrubs. Act[{a]ea alba is no 
doubt included by mistake as it is certainly an herbaceous plant. 

I still think Rhododendron (Azalea) oblongifolium must grow some- 
where in western Louisiana as it is so common in Arkansas, eastern Okla- 
homa and eastern Texas. Don’t you think you should look further for it in 
the valley of the Sabine River? 

It seems to us very doubtful if Philadelphus grandiflorus grows naturally 
in Louisiana and I think your best plan would be to send us a specimen 
now of the plant which you say is often cultivated and sometimes natural- 
ized in the state. No matter if the plants are out of flower if you haven't a 
spare specimen. Flowering sp|ecimen]. 

It is certainly very surprising that there is only one species of Ribes 
in the state. Does not Daubentonia die down to the ground every year? 
I had supposed it was herbaceous. 

On the whole I am rather disappointed in the number of shrubs in Loui- 
siana. Proportionately it is not as great as the number of trees. It would 
be surprising, however, if you or any one else have found them all. 


286 
July 1, 1922. 
We have now examined critically your list of shrubs. I have already 
written you about Philadelphus grandiflorus. Rydberg gives Rapides 
Parish for Rubus carpinifolius. 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 429 


Rosa Treleasei Rydberg. This species grows at Gee Bridge, Bos- 
sier Parish. The specimen is in the herbarium at St. 

According to Rydberg Amorpha tennesseensis should “a added to the list. 
You omitted entirely the Rutaceae, and Acacia angustissima collected by 
Palmer at Natchitoches. In the list Cornus stricta appears twice. One of 
these we think must be C. asperifolia as we have many specimens of that 
species from Louisiana where it appears to be generally distributed. 

Azalea we now make a section of Rhododendron. What you call Vibur- 
num pubescens is the large-leaved form of V. scabrellum. 

The Vines, of which there are several species and genera, are omitted 
from this list. Don’t you think they should be included as they are al- 
ways considered to be shrubs? Will you supply us with a list of these 
and we will incorporate it? 


287 
August 8, 1922. 

I hear for the first time from you of Pinus Sondereggeri. 1 feel very 
skeptical about its being a hybrid. Who named and published the tree? *4 
If it is possible to obtain this information and for us to see specimens at 
once there will probably be time to get some mention of the tree in your 
shrub paper which has now been in the hands of the printer for about 
two weeks. There would not, however, be any time to lose in getting 
the information. The fact that there appear to be a great many of these 
trees would tend to show that it was not a hybrid. Pinus palustris flowers 
so much earlier than Pinus taeda that it would be difficult for these species 
to hybridize. We should certainly see specimens. 

It would surprise us here very much if Cornus amomum was found in 
Louisiana. We certainly have no specimen in the herbarium of this 
northern plant from Louisiana and if you have one I wish you would let 
us see it. For the time being at least we have omitted Cornus amomum 
from your list. 

Gleditsia texana will have to be included among the Louisiana trees. 
I consider this now to be a hybrid *° and have referred to it the tree from 
Shreveport, Louisiana, from which I have collected specimens. Nuttall 
appears to have found it more than a hundred years ago near the mouth 
of the Arkansas River and we have a specimen which you sent from the 
Yazoo River, Mississippi, and one from southwestern Illinois. 

If there is anything more to say about your paper it is not too late to 
do it. The proof of course will be sent to you as soon as we get it. The 
printer, however, is as usual very slow. 

288 
August 22, 1922. 

We have submitted your mysterious Pine to Shaw who has made a 
critical examination of it and finds no trace of Pinus palustris, either in 

“ Cuapman, H. H. Jour. Forestry 20: 734. pl. 1. 1922.

the cone or in the internal structure of the leaf. He pronounces it Pinus 
taeda and I feel sure that he is right. Of course we ought to know if 
possible if such a thing has ever been published, where and by whom. 
If the name is published it should become a synonym of Pinus taeda. 

The principal things I want from you now are a few fruiting specimens 
of Crataegus, especially Sardis 3342, collected by you in flower April 12, 
1919. This is the new species in the Bracteatae Group and I am particu- 
larly interested in it as only two other species are known. I am also anxious 
for fruit of the Viridis species with twenty rose-colored anthers growing 
in the yard of the house on the left hand side of the road along the river 
below Lake Charles. You remember the tree I am sure and how handsome 
it was. This also is possibly undescribed. 

We have from you two Crus-galli species from Pineville, one collected 
April 1912, without any number, and the other numbered XIX., April 24, 
no year. We ought to have fruit of these two trees. No color of the anthers 
unfortunately is given with the specimens. Have you got it? Fruit of 
Bogalusa 3149, April 9, 1919, a Viridis species, is also needed. 

Bogalusa 3151 is a species of the Pulcherrimae apparently undescribed 
if you are sure of the color of the anthers. The flowers on our specimen 
are pretty much faded and the color may have changed. This is interest- 
ing as the only Pulcherrimae we know of in Louisiana. Do you remember 
anything about the size and habit of the plant and have you any other 
notes on the color of the anthers? 

This is all the undescribed Louisiana material we have and if you 
have everything there is the Crataegus material of Louisiana is better 
worked up than that of any other state. You can add to the Louisiana 
trees C. blanda Sargent, Minden, Bush No. 663, August 10, 1901. This 
is a Viridis species with very dark scaly bark. I think we looked at this 
from trees growing near C. aestivalis but I do not find that I made any 
specimen. 

I am most interested now in the Sardis 3342 and in the St. Charles 
Viridis species. I hope you will certainly be able to get them and possibly 
the Pineville and Bogalusa material. Of the latter it would be better to 
get more material of 3151. 


289 
November 7, 1922. 

In your catalogue you mention a Catalogue of the Plants of Southern 
Louisiana by the Reverend Langlois. We have n’t a copy of this. Can 
you get one for us? 

Can you give a locality for Hypericum lobocarpum as being near Louis- 
burg, St. Tammany Parish? We cannot find this name in the atlas and 
are therefore omitting it. In this herbarium there is no specimen of 
Hypericum lobocarpum from Louisiana. Can you let us have one? 

I am afraid your entry of the American Ampelopsis is incomplete. There 
is no specimen of the typical plant here but specimens of two varieties. 
We ought to have better material of this plant in this herbarium. We have 


1965 | EWAN, LETTERS FROM SARGENT TO COCKS 431 


decided to leave out any reference to the type and put in the two varieties 
represented in this herbarium. 

It is too late to send you the page-proof as I hope the article will now 
be printed in a short time. We have done the best we can with it but I 
daresay there are still some omissions. 

Can’t you get for me a quart of acorns of Quercus virginiana? I want 
to send them to a correspondent in South Africa where exotic trees appear 
to do better than in any other part of the world. Before sending it would 
be best to put the acorns in water and send only those which float; those 
which sink will have grubs in them. It will be best to send them in a box 
of soil as acorns lose their germinating power very quickly. 

Are you going to be able to get me the nuts of Carya leiodermis and its 
variety callicoma this autumn? I very much want to plant them here in 
the hope that the trees will prove hardy. 


290 
December 26, 1923. 

I owe you an apology for the long delay in answering your letters of 
October 24th and 29th in regard to various specimens of Hickories sent at 
that time. 

You say that No. 1 which you call /eiodermis is the only one you recog- 
nize. No. 2 is clearly the same thing. I think these trees cannot be referred 
to leiodermis. The branchlets and leaves are much too pubescent as I 
understand that species. We are putting the specimens among the unde- 
termined ones and I hope you will follow these trees up in the spring; as 
I understand them now they do not fit into any of the described species. 
Nos. 3 and 4 are C. glabra [var.] megacarpa which is a common species 
along the Gulf coast. 

Carya ovalis [var.] obcordata from West Feliciana seems to me to 
be rightly determined. Apparently we did not know this tree from Louisi- 
ana before and it is certainly some way beyond its known range; it is a 
good find. 

Your Betula from West Feliciana is a very pubescent but not uncommon 
form of Betula nigra. We shall be glad of one of your specimens of 
Oxydendron from the Natchitoches region. 

I am very sorry indeed to hear that that beautiful Crataegus from south 
of Lake Charles has been cut down before we had an opportunity to de- 
scribe it. You ought to be able, however, to find others in that region. I 
hope you are not going to give up that Selma species which is one of the 
most interesting of all your Crataegus discoveries. 

Castanea alnifolia [var.] floridana is not that species but probably a 
form of Castanea pumila. 

Here we have so far had a very mild winter with a green Christmas. 
Once only the thermometer has been as low as 18 and there has been no 
snow yet to speak of. I trust you are equally fortunate in your part of 
the world. 

With all good wishes for the New Year, believe me,

February 24, 1925. 

Please excuse me for the long delay in answering your letter of Febru- 
ary 5th about tree surgery as practiced by Davey. I am a disbeliever in it. 

In the first place it is very expensive, and when a cavity is filled with 
cement it is impossible to prevent moisture forming between the surface 
of the wood and the cement. This brings on decay and many trees have 
been destroyed in this way. Davey and his system are the produce of 
extreme advertising. The only way to treat a cavity in a tree is to clean 
out thoroughly all decayed wood and then keep the surface painted with 
tar, leaving the cavity open so that what is going on can be watched. Of 
course the tar will have to be renewed from time to time. Sometimes a 
very old tree is so far gone that it is better to cut it down and replace it 
by a young one. 

I hope you are well this winter and enjoying life, and that you are pre- 
paring to come north next summer and do some serious work here on 
your book, 

We have had a very bad winter for plants — no snow, extreme drought 
and some very cold weather. I am afraid there will be many losses in the 
Arboretum before spring really comes. 


292 
March 2, 1925. 

Sudworth has published in last year’s Journal of Forestry (our copy 
now unfortunately in the hands of the binder) Carya Ashei, distinguished 
by 7-9 leaflets and remarkably long stigmas. I have seen the type plant 
from Pensacola, Florida, the only one which has been collected apparently 
with pistillate flowers. One leaf of this tree has nine leaflets; all the others 
have only seven. I do not think it is safe to establish species on such 
scanty material. To me it seems to be a variety or form of Carya ovalis. 
The species, as you know, extends along the Gulf coast to southern 
Mississippi and Louisiana in some of its forms. I wish you would look 
out for such a tree this spring when the Hickories are in flower and see 
if you can find any of them with nine leafletsy or what is more important 
the exceptionally long stigmas. 

I suppose it begins to be a little springlike in your part of the world. 
Here it is cold, dry and generally disagreeable, with a prospect of a good 
deal more winter before us. 

With kind regards, 


293 
March 7, 1925. 
We have all been looking again at your Hickory from Bay St. Louis. 
Judging from the leaves I do not think there can be any doubt that it is 
Carya alba. It is unusual in the thinner husk of the fruit and in the less 
pointed, strongly angled and paler nuts. The nuts of this species are 


1965] EWAN, LETTERS FROM SARGENT TO COCKS 433 


very variable, and I think we can match yours almost exactly from among 
Palmer’s collections west of the Mississippi. I should like to know how 
the bark looks. Would it not be possible to get a photograph of a trunk 
to go with your specimens? 

I am sorry to hear there are more Crataeguses to find but I am not 
surprised. 

It is acting now like an early spring but I suppose we shall have a lot 
more snow. It is still terribly dry and during this week the thermometer 
has been down to 10 above zero.

Your Amelanchier from Alabama is a common northeastern species, A. 
intermedia Spach, but it appears to have been more or less cultivated at 
one time in the southern states for its fruit. 
There are no mosquitos yet in this part of the world and the best thing 
for you to do is to come up to New England and pay us a summer visit. 
You do not say anything about your Louisiana Flora. Are you still 
working on it and, if so, how is it getting on? 
I wish I heard from you oftener, and I much want to see you again but 
I am afraid I shall never get as far from home as Louisiana. You must 
come up and see me. 


295 
August 19, 1925. 

I am not sure that I ever answered your note of June 27th in which 
you ask about a small shrubby Amelanchier in Alabama which grows you 
say in a few places near Selma. 

The name of the species is Amelanchier intermedia Spach. 

I fancy there are still hybrid Oaks and Hickories to find in Louisiana. 

You must certainly come up and see the Arboretum sometime. There 
are few mosquitos here just now and on the whole this has been a wonder- 
ful summer, and the Arboretum has never before looked so well at this 
season.

I am working over a paper to be published in the Arboretum Journal

noticed any mistakes I wish you would call my attention to them. - here 
are misspellings of geographical names and many errors in distribution ; 
the latter are the most important, and I should especially like to know of 
any of these relating to Louisiana trees.

rag to get your note of the 18th. The separates will be sent to you 


T do not believe you dislike clerics more than I do but I cannot help 
feeling sympathy, as I wrote you, for the unfortunate old Bishop from 
Arkansas. 

I hope you will send us a specimen of the Oak from Bay St. Louis. 

We have no record here that Raphidophyllum hystrix grows in Alabama 
and of course we should be glad to get a specimen from there.

I am distressed at the news conveyed about your health in your note 
of the 17th of December. I can only hope that your views of the future 
are not as bad as you state. I wish there was something I could do for 
you or send you, and if you will only intimate something you would like, 
some book perhaps to read, you shall have it if I can procure it for you. 
I really cannot tell you how badly I feel. Of course you will be out again 
in the spring. 

I am still fairly well and getting to the Arboretum every day but am 
too old to enjoy life 

As I hope you know, I am, 

Always sincerely and devotedly yours,

January 11, 1926. 

I am certainly sorry that you will not be able to meet Dr. Councilman 
for he is a delightful and learned man, and has a charming wife. More- 
over, he has become much interested in plants, especially in the study 
of peculiar fungous growth on the roots of Oak-trees. I am sorry to say 
he has not sent me his New Orleans address but if you have it I hope 
you will write to him. 

You have asked me about thrilling novels which is one of my specialties, 
and I will see in future that you are well supplied with them. I have 
already sent you three or four and others will follow. I shall feel that I 
have n’t lived in vain if I have introduced you to “Nick Carter,” 27 the 
most thrilling of all, and among the long series certainly are some of 
the best detective stories which have ever been read. 

Let me hear occasionally if you get any pleasure from the books I send 
you and I hope that your health is improving. 

. oe Addressed to Professor Cocks at Bay St. Louis, Mississippi, where he had moved 

a 

Fictional character in dime novels fathered about 1885 by J. R. Coryell (?) but 


publicized in any event by pect and Smith, New York, producers of over 1000 
stories about him by several author.

I have n’t heard a word from Councilman since he reached your part 
of the world, but I have heard of his visit to Natchez through Miss Comp- 
ton and that he is now laid up in bed in New Orleans and obliged to 
postpone starting for Havana. I am afraid he has n’t been able to see you 
which I greatly regret for he is a delightful person. 

As you are a Britisher and no doubt a tea-drinker I am sharing with you 
some tea sent me by J. P. Morgan which has a remarkable reputation. I 
cannot vouch for this personally as I never drink tea. I believe it is better 
with lemon than with milk. If you don’t like it there are probably plenty 
of people to whom you can give it. 

I hope you are getting on better and that I shall hear from you again 
before long. 

With kind regards,

March 19, 1926. 

I find in our herbarium we have a Crataegus uniflorae species with very 
small flowers collected by Harbison April 19, 1911, and labeled “C. uni- 
flora at Professor Cocks’s along road in the woods.” Have you ever col- 
lected any fruiting specimens of this plant and do you know anything 
about it? I am not quite sure what he means by your place, whether it 
was in Mississippi or at Sardis, Alabama, where you seem to have collected 
a good deal. We have a specimen collected by you there on April 2nd, 
1919, in flower (No. 3342) with twenty stamens and yellow anthers. What 
is this? Have you a fruiting specimen? This may be undescribed. We 
also have complete fruiting material of a Flavae species (No. 968) col- 
lected in 1915 and 1916 at Sardis. Do you know anything about this? 

We are trying here with much difficulty and not much success to arrange 
a lot of unplaced Crataegus material and badly need help. 

I hope that you are improving and able to enjoy the spring which is 
now probably upon you. It is still wintry here with the ground covered 
with snow, 

With kind regards and all good wishes,

November 1, 1926. 
The Crataegus No. 4126 from Chestnut, Louisiana, appears to be with- 
out doubt Crataegus drymophila Sargent. 
Faithfully yours,

COMPARATIVE ANATOMY OF THE LEAF-BEARING 
CACTACEAE, XIV 


PRELIMINARY OBSERVATIONS ON THE VASCULATURE OF 
COTYLEDONS 


I. W. BatLey } 


A CONSENSUS OF ANATOMICAL EVIDENCE presented in preceding papers 
of this series clearly indicates that the most primitive and structurally 
least specialized surviving representatives of the Cactaceae occur in the 
genus Pereskia. Such better known species as P. sacharosa Griseb., P. bleo 
DC. and P. grandifolia Haw. have long been recognized by various taxono- 
mists as having a habit of growth and absence of accentuated succulence 
characteristic of many typically woody dicotyledonous trees and large 
shrubs. These species in contrast to other representatives of the Cactaceae 
exhibit only slight evidence of incipient trends of divergent structural 
specializations internally (Bailey, 1962, 1963c). The comparatively thin 
large leaves of adult plants have typical pinnate venation, their numerous 
lateral veins extending diagonally toward the margins of the lamina (Fic. 
1 


Pereskias of such other species as P. aculeata Mill. (Bailey, 1962), P. 
humboldtii Britt. & Rose, P. weberiana K. Schum., P. diaz-romeroana 
Card. (Bailey, 1963a) and P. guamacho Web., P. colombiana Britt. & 
Rose, P. cubensis Britt. & Rose, and P. portulacifolia Haw. (Bailey, 
1963d), although exhibiting variations in stature and habit of growth, as 
well as more or less incipient internal trends of divergent anatomical 
specializations, have leaves with pinnate venation (Bailey, 1960). 

Many of the leaves of these taxa, with the possible exception of those of 
P. aculeata and P. cubensis, tend at times to form more extensively arcuate 
lateral veins (Fic. 2). Particularly in some leaves of P. Aumboldtii and 
related taxa of Peru and Bolivia, and in some aberrant ones of P. gua- 
macho and P. colombiana, modifications of pinnate vasculature occur. In 
such leaves the lateral veins which diverge from the midvein in the basal 
and central part of the lamina become more conspicuous and extensively 
arcuate with concomitant reduction of those in the apical parts of the leaf 
(Fic. 3). These modifications of pinnate vasculature appear phylogeneti- 
cally to be transitional toward the pseudopalmate and palmate venation 
which occurs in the comparatively thick succulent leaves of the structurally 
more highly specialized genera Pereskiopsis and Quiabentia (Fics. 4, 5). 

The leaves of Pereskia pititache Karw. (P. conzattii Britt. & Rose), P. 
autumnalis (Eichlam) Rose, and P. nicoyana Web. are particularly signif- 
icant in these connections. Not only are they more succulent than those 
of P. sacharosa, P. bleo, and P. grandifolia, but also vary markedly in size

and form (Bailey, 1960). In some of them, the venation is of the modified 
pinnate form discussed in the preceding paragraph whereas in others the 
vasculature becomes truly pseudo-palmate and even closely palmate. 

In the dicotyledons as a whole changes in patterns of foliar vasculature 
are not consistently unidirectional. Transitions from pinnate to palmate 
venation and vice versa are of not uncommon occurrence. Suggestive con- 
clusions regarding phylogenetic changes in vasculature within a specific 
family therefore, are dependent upon extensive summations of cumulative 
circumstantial evidence. In the genera Pereskia, Pereskiopsis, and Quia- 
bentia, a totality of evidence now available is strongly indicative of a 
phylogenetic transition from pinnate venation in structurally primitive 
pereskias to palmate vasculature in anatomically more highly specialized 
surviving representatives of Pereskiopsis and Quiabentia (Bailey, 1964a). 

In his extensive survey of seeds, embryos, and seedlings, Ganong (1898) 
concluded that the Cactaceae is a family in which succulence and other 
adaptations for survival in excessively arid environments work backward 
phylogenetically into earlier and earlier stages of the development of the 
epicotyl, there commonly being conspicuous retardation in the appearance 
of such divergent changes in the cotyledons and hypocotyl of germinated 
embryos at least prior to growth of the plumule. If this retardation of 
evolutionary changes in cotyledons of the Cactaceae is as general as it 
appears to be, it is of possible significance to compare the cotyledonary 
vasculature in Pereskia with that in Pereskiopsis and Quiabentia. Of 
course it should be fully recognized in this connection that ontogeny does 
not closely parallel phylogeny in many cases. However, as recognized by 
Ganong, the divergent trends of specialization in the Cactaceae are SO 
bizarre and so closely correlated from ecological and physiological points 
of view with adaptations for survival in arid environments as to leave few 
uncertainties regarding the directions in which phylogenetic changes are 
progressing. Furthermore, the Cactaceae is a family in which transitional 
stages of phylogenetic changes are more consistently and adequately pre- 
served in surviving representatives than is commonly the case in many 
other families of the dicotyledons 

Thus far, I have been able to obtain seedlings of the following species

1965 | BAILEY, LEAF-BEARING CACTACEAE, XIV 447 


In my paper on “Nodal anatomy in retrospect” (1956), I presented the 
results of an extensive reconnaissance of seedlings from 99 families of the 
dicotyledons. In 60 per cent of them the cotyledons are attached at 2-trace 
unilacunar nodes. Within this category there is a tendency at times in 
some families for the cotyledons to be pinnately veined (Fic. 9). In the 
structurally most primitive pereskias, viz. P. sacharosa and P. grandifolia 
which have pinnate venation in the leaves of both juvenile and adult 
plants, the cotyledons have this 2-trace pinnate form of vasculature. 
Therefore a totality of evidence suggests that the cotyledons of ancestral 
Cactaceae possessed pinnate venation during early stages of the differen- 
tiation of the family. 

In the case of P. sacharosa and P. grandifolia, the thin oblong-elliptical 
or slightly ovate cotyledons, which are relatively small in seeds, continue 
to enlarge and appear to be physiologically functional for considerable 
time during earlier stages of the development of the juvenile plant, i.e., for 
a period which may be as extensive as several months. During the expan- 
sion of the cotyledons they retain their original form and internal pinnate 
venation. Particularly during the earliest stages of the enlargement of the 
cotyledons, the two traces commonly tend to be distinct and separate in 
the upper hypocotyl, at the nodal level, and in the basal part of the lamina 
(Fics. 10, 12). During later stages of the enlargement of the cotyledons 
the xylems of the two traces tend to broaden and to become more or less 
Closely approximated (Fics. 11, 13). During such changes in the two 
traces, approximation of the two strands of phloem may be much less 
precocious than in the xylems. : 

The cotyledons in the large seeds of P. aculeata and of germinated 
embryos prior to development of the epicotyl are larger than those that 
occur in other representatives of the Cactaceae. These thin broadly ovate 
or slightly cordate cotyledons have a 2-trace pinnate form of vasculature 
(Fic. 14). The basal lateral veins are not extensively arcuate, thus re- 
sembling in this respect the venation in cotyledons of P. sacharosa and 
P. grandifolia. 

In contrast to this the cotyledons in seeds of P. diaz-romeroana and P. 
humboldtii and of germinated embryos prior to the development of the 
epicotyl are much smaller than those of P. aculeata and are of more nearly 
oblong rather than ovate form. In my few seedlings of P. diaz-romeroana, 
the cotyledons have a simplified form of pinnate venation without conspic- 
uous accentuation of the lateral veins (Fic. 17), whereas in those of P. 
humboldtii the cotyledons exhibit a tendency at times to accentuate the 
more extensively arcuate basal lateral veins (Fic. 16). It should be men- 
tioned in this connection that the pereskias of Peru and Bolivia are much 
reduced in stature and commonly have very small leaves. T his may be a 
factor in the simplified venation of early deciduous cotyledons of P. diaz- 
romeroana. : 

Pereskia pititache of which I have numerous seedlings has oblong- 
elliptical cotyledons with pinnate venation, but with a tendency to form 
extensively arcuate lateral veins (Fic. 15). However, they do not exhibit 


448 JOURNAL OF THE ARNOLD ARBORETUM [VOL. 46 


transitions to truly pseudo-palmate vasculature such as occurs in the 
leaves of juvenile and adult plants. The cotyledons of the closely allied 
taxon, P. autumnalis, have similar somewhat modified pinnate venation. 

The leaves of Pereskiopsis are very variable in size and form, not only 
in different collections of a taxon or clone when grown under different 
environmental influences, but frequently also in different parts of a single 
adult plant. Excessive emphasis by earlier taxonomists upon apparent 
differences in the form of leaves, when limited collections were available, 
has led to serious difficulties and uncertainties in identifying the numerous 
putative species of the genus. However, the leaves of adult Pereskiopsis, 
regardless of extreme variations in size and form and concomitant taxo- 
nomic uncertainties are comparatively succulent and consistently pseudo- 
palmately or palmately veined (Fics. 4, 5). This is true except for the 
small first-formed leaves of some short shoots which may at times exhibit 
transitions from modified pinnate venation (Fic. 8) to palmate vascula- 
ture. 

In seedlings of Pereskiopsis porteri (T. S. Brandeg.) Britt. & Rose, P. 
blakeana Ort., and three collections from Oaxaca of uncertain taxonomic 
affinities, the nearly oblong-elliptical cotyledons have a 2-trace pinnate 
form of vasculature (Fic. 18). At times the lateral veins which diverge 
from the mid-vein in basal and central parts of the lamina become accen- 
tuated in their arcuate extensions (Fics. 19, 20), thus resembling in this 
respect the venation in cotyledons of Pereskia pititache and P. humboldtii. 

The first-formed leaves of juvenile plants from these seed collections 
commonly vary more or less markedly in size and form. At times the 
ontogenetic sequences are complicated by the occurrence of rudimentary 
evanescent appendages with abnormal vasculature. Frequently the normal 
first-formed leaves differ strikingly from those of adult plants, tending to 
be narrowly lanceolate with fewer extensively arcuate lateral veins (Fic. 
7) in contrast to the broader leaves of adult plants (Fic. 5). Not infre- 
quently there is obvious ontogenetic retardation in the attainment of 

palmate venation; the first leaves of the juvenile stem re modified 
pinnate venation (Fic. 6) rather than truly palmate vasculatu 

Thus, in agreement with work of Ganong (1898), the ae in the 
attainment of pseudo-palmate and palmate venation in cotyledons of 
Pereskiopsis as well as in those of Pereskia pititache and Pereskia hum- 
boldtii strengthens a concept of divergent evolutionary change from pin- 
nate to palmate venation in the Cactaceae. For, if the reverse were true, 
one would expect to find palmate venation in the leaves of the most primi- 
tive surviving representatives of the family and at least some cotyledons 
which retain palmate vasculature. 


CONCLUSIONS 
The Cactaceae is a family which provides unusually favorable evidence 
for the study of highly divergent trends of morphological specialization. 
These are so bizarre and so closely correlated from ecological and physio- 
logical points of view with adaptations for survival in arid environments 


1965 | BAILEY, LEAF-BEARING CACTACEAE, XIV 449 


as to leave few uncertainties regarding the directions in which phylogenet- 
ic changes are progressing. Furthermore, an unusually comprehensive 
and adequate record of the divergent trends of specialization is preserved 
in surviving representatives of the family. 

A totality of available evidence strongly indicates that ancestral Cactac- 
eae had attained an advanced level of anatomical structure in their 
cambium, xylem, phloem, and cotyledons prior to the development of ac- 
centuated succulence and other trends of excessively divergent anatomical 
specializations (Bailey & Srivastava, 1962; Srivastava & Bailey, 1962). 
The ancestral trees and large shrubs of normal woody structure appear to 
have borne relatively broad thin leaves rather than succulent terete ones 
as in surviving representatives of the Opuntieae. The ancestral leaves 
evidently possessed typical pinnate venation and stomata of the “true 
rubiaceous” form (Bailey, 1964b). The germinated embryos, at least prior 
to the development of the epicotyl, had 2-trace unilacunar vasculature and 
both the cotyledons and first-formed leaves exhibited pinnate venation. 

Evidence of a phylogenetic transition from pinnate to palmate venation 
in the relatively succulent leaves of Pereskia pititache, P. autumnalis, P. 
nicoyana, Pereskiopsis, and Quiabentia is now available. In this connec- 
tion, retardation in the extension of palmate venation into cotyledons of 
Pereskia and Pereskiopsis as well as in the first-formed leaves of the latter 
genus provides corroborative evidence of considerable significance regard- 
ing a phylogenetic transition from pinnate to palmate vasculature in the 
Cactaceae. 

It should be noted in conclusion that summations of evidence available 
in the most primitive surviving representatives of the Cactaceae suggest 
that ancestral members of the family may have possessed spines and hairy 
areoles during earlier stages of their differentiation as a family. More 
significant from physiological and biochemical points of view appear to be 
the likelihood that ancestral Cactaceae possessed abundant mucilage cells 
and an incipient tendency in their metabolism toward the formation of 
unusually abundant crystals of calcium oxalate and other calcium salts of 
organic acids (Bailey, 1965). Furthermore there appears to have been an 
incipient tendency toward the storage of unusually abundant starch in the 
secondary xylem of the main stem and the larger roots of mature plants, 
and likewise at times for the accumulation of large amounts of stored 
protein.

CACTACEAE, XV 


SOME PRELIMINARY OBSERVATIONS ON THE 
OCCURRENCE OF “PROTEIN BODIES” 


I. W. Barrey ! 


IN THE NINTH PAPER of this series (1963c), I called attention to the 
occurrence of filamentous bodies in the vessels of Pereskia sacharosa 
Griseb., P. grandifolia Haw., P. bleo DC., and P. tampicana Web. which 
are rarely, if ever, present in the vessels of other categories of Pereskia or 
in those of Pereskiopsis and Quiabentia. These structures differ markedly 
in size and form. Many of them are tenuous threads a fraction of a micron 
in diameter, which are variously elongated, oriented, and aggregated (Fics. 
1 & 3). Others are coarse strands up to ten micra in diameter and of vary- 
ing lengths and formations (Fic. 4). Some of the smaller more compact 
aggregations of slender filaments resemble the filamentous forms of “pro- 
tein bodies” originally found and intensively investigated by Molisch 
(1885, Figs. 3 & 5) in the outer parenchymatous living tissue of young 
stems of Epiphyllum. 

In the secondary xylem of this anatomically most primitive category of 
pereskias (Bailey 1962, 1963c) globular forms of bodies may occur in 
parenchymatous cells adjacent to vessels (Fics. 5 & 6), in the first- 
formed unlignified parts of rays in roots and infrequently in lignified ray 
cells which contain abundant starch. Filamentous and stellate bodies are 
in general of rare occurrence in parenchymatous cells of the xylem except 
at times in the innermost parts of the rays in roots. 

In the main stem and larger roots of P. sacharosa collected for me by 
Carenzo and Legname, from a tree in its native habitat in Jujuy province 
of northern Argentina, large deposits of material occur in the unlignified 
parenchyma of the broad zone of secondary phloem. These bodies vary 
considerably in form. The last formed cells of the multiseriate rays com- 
monly contain abundant minute more or less spiny granules with frequent 
transitions to relatively large stellate bodies composed of short, slender, 
radially oriented filaments (Fic. 2). Cells in the outer modified parts of 
the rays and of the inner cortex frequently contain nearly globular 
bodies.? Filamentous forms resembling those which occur in the vessels of 
the secondary xylem are of sporadic occurrence in ray cells of the phloem, 
but may be present at times in the axially oriented parenchymatous cells 
of parts of the phloem which contain or once contained functioning sieve 
tubes

The only collections of P. tampicana available to me are young stems of 
cultivated plants obtained by Dr. Boke at Victoria in Tamaulipas, Mexico. 
These small stems with scanty xylem and phloem have filamentous bodies 
in their vessels and globular ones in parenchyma adjacent to vessels (Fic. 
6). Although most of the unlignified parenchyma of the phloem and 
cortex does not contain stellate or globular bodies, some of the ray cells 
and axially oriented ones (more or less closely associated with sieve tubes) 
are filled with deposits of diversified forms. These vary from slender fila- 
ments to coarse strands (as in the vessels of the xylem) and exhibit various 
transitions to homogeneous appearing masses of diversified forms, sizes and 
orientations (Fic. 7). 

At present there are serious taxonomic difficulties and uncertainties in 
dealing with P. grandifolia, P. bleo, and such putative segregates as P. 
moorei Britt. & Rose and P. bahiensis Giirke. These uncertainties are 
much intensified in the case of plants growing in greenhouses and botanical 
gardens remote from their native habitats. Regardless of whether these 
plants are ultimately shown to be closely related distinct species or merely 
geographical variants of a single widely ranging taxon, it is significant that 
the anatomy of their stems and roots is remarkably similar (Bailey 1961, 
1963c). Therefore, in discussing the occurrence of “protein bodies” I shall 
confine myself at this time to collections from mature plants growing in 
Brazil, Venezuela, and Costa Rica. 

In material of P. grandifolia kindly collected for me by Dr. Castellanos 
in Brazil, filamentous bodies occur in the vessels of stems and roots. The 
phloem of the larger roots contains abundant deposits of bodies in its ray 
and axially oriented parenchyma. These bodies are more or less closely 
aggregated minute hollow appearing globules or small rings, but exhibit 
frequent transitions to stellate forms as in P. sacharosa. The bodies in the 
phloem of the main stem are of similar forms but less abundant. 

In specimens of a mature plant, either P. grandifolia or P. bleo, kindly 
collected for me by Dr. Steyermark in Venezuela, filamentous bodies occur 
in the vessels of both stems and roots, and globular ones in parenchymatous 
cells adjacent to vessels. The ray cells in the broad secondary phloem of 
the main stem and larger roots are densely packed with granular and 
globular contents, as are the unlignified cells in the first formed parts of 
the rays of the xylem in roots. In the tangentially expanded cells of the 
cortex, there are transitions to ring-shaped bodies (Fic. 9) and to frothy- 
or vacuolated-appearing formations (Fic. 10). In these cortical cells 
coarsely filamentous bodies are of sporadic and infrequent occurrence. 

In material of an adult plant, either P. grandifolia or P. bleo, kindly 
collected by Dr. Rodriguez in Costa Rica, there is a tendency at times for 
fewer of the vessels to contain filamentous bodies than in comparable 
material of the two preceding collections from Brazil and Venezuela. The 
ray cells and axially oriented parenchyma in the broad zone of the 
secondary phloem of the main stem contain very abundant globular 
bodies. Where excessively abundant, they tend to fuse in highly diversi- 
fied formations, viz. convoluted coarse strands, massive rings, and lobate 


*@,

formations (Fic. 8). Slender filamentous bodies are of sporadic and in- 
frequent occurrence. The phloem in large roots of this plant contains less 
abundant deposits in finely globular forms, hollow appearing bodies, or 
rings of diverse sizes which when very abundant fuse to form extensive 
vacuolated or frothy deposits. 

In a second category of pereskias * which includes P. aculeata Mill., P. 
humboldti Britt. & Rose and allied taxa, and P. pititache Karw. (P. con- 
zattu Britt. & Rose) and related species, globular bodies tend to occur in 
the xylem and phloem of stems and roots, filamentous forms being absent 
in my collections of these plants. 

Within this category of pereskias, P. pititache, P. autumnalis (Eichlam) 
Rose and P. nicoyana Web. exhibit less divergent trends of anatomical 
specializations except in the basal parts of their large trunks (Bailey, 
1963b). Globular bodies are of less abundant occurrence in the secondary 
xylem except at times in the first-formed parts of the rays in roots. In ray 
cells and axially oriented parenchymatous ones of the phloem, the globular 
bodies although varying considerably in size and number, commonly tend 
to be comparatively few and of relatively large size. However, they may 
fuse at times into beaded or lobed formations (Fic. 11). 

In P. humboldtii and related taxa of Peru and Bolivia, which are of 
more or less reduced and modified stature, advanced trends of divergent 
anatomical specializations occur in the roots (Bailey, 1963a); those 
species being characterized by forming much enlarged tuberous swellings. 
The size and the distribution of globular bodies in the secondary xylem 
and phloem of the stems of these plants resemble those that occur in P. 
pititache and allied taxa. However, in some stems the parenchymatous 
cells of the phloem and cortex tend to form extensive massive deposits, 
but without the transitions to filamentous structures such as occur in P. 
tampicana. In parts of the root system, bodies of globular forms are 
abundant in the rays of the secondary xylem. Where closely aggregated, 
they may at times exhibit transitions to lobed formations or to short rods. 

From ecological and physiological points of view, it is particularly 
significant that the soft succulent tissue in the large tuberous swellings is 
devoid of globular bodies as well as starch, but contains numerous large 
cells with mucilaginous contents and others with druses of calcium oxalate. 
This suggests that the tubers may function at least seasonally in the re- 
tention of moisture rather than as organs for the storage of starch and 
other food substances. 

The scandent P. aculeata is anatomically the most divergently special- 
ized representative of the genus Pereskia (Bailey, 1962). The variations 
in the structure of the stems and roots are so extensive and highly variable 
as to necessitate more adequate collections of this species than are avail- 
able to me at present before reliable generalizations regarding the occur- 
rence of globular bodies can be attained. In available material of stems 
and roots, the parenchymatous cells of the pith and cortex as well as those 

®For a description of three anatomically distinct categories of pereskias see the 
second paper of this series (1961). 


456 JOURNAL OF THE ARNOLD ARBORETUM [ VOL. 46 


of the xylem and phloem contain abundant starch. Few of them contain 
granular and globular bodies, Filamentous and stellate bodies do not 
occur in the secondary phloem, nor in vessels of the xylem. The tyloses 
in vessels frequently contain abundant starch but infrequently globular 
bodies in addition. In some stems and roots, the cells of the phelloderm 
are devoid of starch and contain abundant granular and small globular 
forms of material. 

Pereskias of the third category, viz. P. guamacho Web., P. colombiana 
Britt. & Rose, P. cubensis Britt. & Rose and P. portulacifolia Haw., tend 
to form trees under favorable environmental conditions. Divergent trends 
of anatomical specializations are largely confined to the roots (Bailey, 
1963d), but without leading to the formation of tuberous enlargements 
such as characterize the pereskias of Peru and Bolivia. In the xylem and 
phloem of stems and roots of the four species, the bodies when present 
tend to be of globular forms, stellate and filamentous ones being absent. 
In some collections of P. guamacho, where the globular bodies become very 
abundant and closely aggregated in cells of the secondary phloem, transi- 
tions to more massive irregularly rounded deposits and frothy- or vacuo- 
lated- ie) i ones occur in the ray and axially oriented parenchyma 
(Fic 

It. s an be noted in passing that in the first category of pereskias, 
which characteristically tend to form filamentous bodies in many of their 
vessels, some of the fully matured lignified vessels may contain merely 
vestiges of protoplasmic contents and at times globular bodies. In the 
second and third categories of pereskias, which do not form filamentous 
deposits in their vessels, vestiges of protoplasmic contents may likewise 
persist in some of the fully matured vessels. Occasionally globular de- 
posits may occur in a vessel as well as in parenchymatous cells adjacent 
to it. 

In striking contrast to Pereskia the cells in comparable stems and roots 
of the relatively succulent and anatomically more divergent genera Peres- 
kiopsis and Quiabentia (Bailey, 1964) do not contain filamentous, stellate 
or massive deposits of material. This is true regardless of whether collec- 
tions were obtained from greenhouses, botanical gardens or from adult 
plants growing in their native arid environments. Although diversified 
forms of “protein bodies” do not occur in my extensive collections of 
stems and roots of Pereskiopsis and Quiabentia as they do in Pereskia 
when preserved in FAA,* conspicuous spindle-shaped ones occur at times 
in the epidermal and sub-epidermal cells of living leaves of Pereskiopsis 
| Boke B-18| when grown in a greenhouse at Norman, Oklahoma. These 
bodies closely resemble in size and form those encountered by Molisch 
(1885, Fig. 1) in living tissue of Epiphyllum. In the epidermis the bodies, 
commonly one to each cell (Fic. 12), are oriented parallel to the surface 
of the leaf, whereas in the mesophyll they are arranged more or less at 
right angles to the surface. As in Epiphyllum, the spindles are composed 


*Forty per cent formaldehyde, five parts: glacial acetic acid, five parts: 50 per cent 
ethyl alcohol, ninety parts. 


ct

of more or less closely compacted aggregations of slender filaments ar- 
ranged parallel to the long axis of the body. In living cells, the bodies are 
conspicuously anisotropic in polarized light, indicative of crystalline com- 
position. In some leaves, the bodies consist at times of diffusely aggre- 
gated strands of coarser texture. Bodies of similar size and form occur in 
some living leaves of Pereskia aculeata and P. grandifolia. 

Such occurrences in living leaves of Pereskia and Pereskiopsis suggest 
that material conveniently available in greenhouses should provide favor- 
able specimens, not only for a reconnaissance of the occurrence of spindle- 
shaped bodies in various species of Pereskia and Pereskiopsis, but also 
critical material for detailed cytological, physiological, and biochemical 
investigations. 


DISCUSSION 


The structures dealt with on preceding pages obviously are extraordi- 
narily variable in size, form, abundance, and distribution in different parts 
of a plant, but commonly exhibit transitions from one form to another, 
not only in neighboring cells of the same tissue, but also within the limits 
of a single cell. This is suggestive of possible fundamental similarities in 
their composition. 

In the case of living tissue of Epiphyllum, which contains many of the 
essentially similar diverse forms of these bodies, Molisch’s extensive tests 
of the solubilities, color reactions, and general behavior of the bodies in 
acids, alkalies, and various other chemical reagents provided much cumu- 
lative evidence in substantiation of proteinaceous composition. 

In my collections of stems and roots preserved in FAA the diverse forms 
of the bodies give consistently rapid positive tests with Millon’s reagent, 
as do the spindle-shaped ones in living leaves of Pereskiopsis prior to their 
longitudinal contraction, lateral expansion, and ultimate solution. Un- 
fortunately this test, by itself, is not conclusive proof of solely protein- 
aceous composition. However, in stems and roots fixed in FAA, the bodies 
of crystalline and amorphous forms give a positive violet coloration with 
the Biuret test. The crystalline spindle-shaped bodies in living leaves dis- 
solve so rapidly in copper sulphate and sodium hydroxide that it is difficult 
to obtain a reliable positive test with the Biuret reagents. But, when the 
living tissue is killed with the aldehyde fixatives now utilized in light and 
electron microscopy, the bodies persist for a number of days giving a posi- 
tive violet coloration with the Biuret test. Furthermore, when sections are 
treated with acid fuchsin the bodies stain as do other cell constituents of 
known proteinaceous composition. In addition, the consistent similarity in 
the staining of the bodies and that of cell inclusions of known protein- 
aceous composition when treated with toluidine blue, Haedenhein’s iron 
alum haematoxylin, and other staining reagents, provides much cumulative 
corroborative evidence. Thus, there appears to be no valid objection to 
concluding that the bodies in question are at least of partly proteinaceous 
composition. 


458 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


f course, in dealing with the color reactions of the smaller forms of 
the diversified bodies, it is essential to differentiate them with care from 
nuclei, coagulated protoplasm, plastids, and from deposits of “slime” in 
sieve tubes. 

The common occurrence and abundance of the diverse forms of protein 
bodies raises a number of fundamental questions regarding metabolic 
phenomena in cells of the Cactaceae. In my extensive collections, such 
bodies do not occur in cells concerned in the formation of mucilage or 
crystals of calcium oxalate. Nor do they occur in the lignified libriform 
fibers which function at least seasonally in the storage of starch. Although 
not invariably absent in lignified parenchyma containing starch or invari- 
ably present in unlignified cells devoid of starch, there appears in general 
to be an inverse correlation between metabolic activity in cells concerned 
in the storage of starch and that during the deposition of abundant protein 
bodies. 

In the case of plants growing in their arid native habitats, the abundance 
of proteinaceous bodies in the basal part of the main stem and larger roots 
raises questions of much ecological, physiological, and biochemical signifi- 
cance. Are such occurrences indicative of at least seasonal accumulation 
of reserves of utilizable proteinaceous substances? Molisch concluded that 
the protein bodies are reserve products whereas Chmielewsky (1887) re- 
garded them as excretions. Neither of these investigators provided con- 
clusive evidence in support of their generalizations. The filamentous 
bodies in fully matured vessels of the xylem and those in crushed dead 
parts of the phloem may no longer be potentially available to the plants 
and thus might be regarded as excretory. The only evidence available to 
me at present in favor of Molisch’s interpretation is in two plants having 
affinities to Pereskia sacharosa. In the case of specimens obtained by 
Carenzo and Legname from a plant growing in its native habitat in north- 
ern Argentina, the collections were made during the resting, “winter” 
season after abscission of the leaves. In this plant, as indicated earlier in 
this paper, abundant protein bodies occur in the basal part of the main 
stem and larger roots. On the contrary, in comparable material collected 
for me by Dr. Cardenas during the active growing and flowering season, 
but from a plant at somewhat higher elevation in Bolivia, filamentous 
bodies are present in the vessels, but diverse forms of proteinaceous bodies 
are absent or of sporadic occurrence in the phloem, cortex, and phelloderm. 
In spite of possible taxonomic and environmental uncertainties, this at 
least suggests that proteinaceous material in living cells of the phloem and 
cortex, present during the resting season, may be utilizable during seasons 
of active growth. More adequate and conclusive evidence can be obtained 
only by detailed investigations of living plants of the same taxon growing 
together in the same habitat and at different seasons of the year. 

Evidence obtainable from my preliminary investigations of the form, 
distribution, and abundance of protein bodies in more or less haphazardly 
available collections indicates much variability in different tissues, not 
only in different collections of the same taxon, but also in stems of differ- 


1965] BAILEY, LEAF-BEARING CACTACEAE, XV 459 


ent sizes and stages of development within the same plant. For adequate 
clarification of the significance of this variability it will be necessary to 
study the living tissues of stems and roots of plants growing in their native 
arid environments. From significant ecological, physiological, and bio- 
chemical points of view it is essential that this be done, particularly in 
adequate correlation with metabolic phenomena involved in the production 
of mucilage, of large amounts of organic acids and their calcium salts, and 
also in the accumulation and possible seasonal depletion of unusually 
abundant starch in the secondary xylem of large stems and roots. 

It should be noted in conclusion that my collections from adult plants 
growing in their native habitats were preserved in FAA. The diverse forms 
of protein bodies in stems and roots have not dissolved after prolonged 
treatment in this fixative and subsequent mounting in diaphane for perm- 
anent slides. However, the possibility exists that changes in form may be 
induced by fixation in FAA. Molisch (1885) found that in the case of 
living cells of Epiphyllum the elongated and spindle forms of the bodies 
contracted longitudinally and expanded laterally prior to dissolving in 
acids and other reagents. The spindle-shaped bodies in living leaves of 
Pereskiopsis behave similarly. Even in the least drastically modifying 
modern methods of fixation, the spindles may expand, or they may contract 
more or less laterally and at times even longitudinally. Transitions from 
anisotropic crystalline composition to isotropic amorphous form occur in 
some reagents. 

The persistence of anisotropic filaments and elongated bodies in associa- 
tion with isotropic globular ones in the same section of a stem or root 
makes it appear unlikely that all of the amorphous globular and more 
massive forms are due to modifications of crystalline filamentous ones in 
FAA. I had hoped to test the possibility of such changes by obtaining 
living material from easily accessible greenhouses. Thus far none of the 
numerous stems from the unnatural environments of greenhouses contain 
protein bodies after fixation in FAA with exception of two collections from 
the Missouri Botanical Garden. Unless I can obtain living stems of such 
sporadically occurring specimens in greenhouses, it will be necessary to 
study the behavior of globular forms of bodies in living stems and roots of 
plants growing in their native habitats. 

The presence of filamentous bodies in the vessels of one category of 
pereskias and their absence in the vessels of two other categories, and 
of Pereskiopsis and Quiabentia provides some evidence of considerable 
taxonomic significance. However, the occurrence, distribution, and di- 
versified forms of the protein bodies in haphazard collections of the second 
and third categories of pereskias are highly variable. Before utilizing 
conspicuous differences in the form and eae rath of protein bodies as 


sive investigation is hardly ete from a solely taxonomic point of 
view unless significant ecological, physiological, and biochemical data are 
obtained at the same time.

THE DIRECTOR’S REPORT 


THE ARNOLD ARBORETUM DuRING THE FiIscAL YEAR ENDED 
JuNE 30, 1965 


THE ARNOLD ARBORETUM WAS TWICE HONORED during the year: by the 
Massachusetts Horticultural Society and by the United States Department 
of the Interior. The Trustees of the Massachusetts Horticultural Society 
voted in November to award the large Gold Medal of the Society to the 
Arnold Arboretum for its horticultural leadership. The citation accom- 
panying the medal notes that ‘new plants from the far corners of the 
world and new originations by its geneticists are combined with the rich 
collections of the past to enable the plant lover to watch their growth and 
evaluate their beauty. Its library, publications and herbarium are world 
renowned. Everyone who gardens owes it to himself to visit and benefit 
from this great horticultural center.” Dr. Carroll E. Wood, Jr. accepted 
the medal for the Arboretum staff from Mr. Oliver Wolcott, President, 
during the annual meeting of the Society. 

In January, the Secretary of the Interior, Stewart L. Udall, announced 
that the Arnold Arboretum was designated for recognition as a National 
Historic Landmark. The nominating citation read, ‘As well as being a 
beautiful park, the Arnold Arboretum is now America’s pre-eminent insti- 
tution for research in woody plants.” The award was accepted jointly by 
Mayor John F. Collins, for the City of Boston, as owner of the land; by 
Commissioner William J. Devine, for the Department of Parks and Recre- 
ation, for its maintenance service of portions of the property; and by 
Mr. Nathan M. Pusey, for the President and Fellows of Harvard College, 
trustees of the Arboretum and responsible for its staff, collections, and 
research contributions. About 500 institutions or localities have been 
similarly honored throughout the country. Those responsible for the 
Arboretum agree to preserve so far as practicable and to the best of their 
ability, the historical integrity of this important part of the national heri- 
tage, “to continue to use the property only for the purposes consistent with 
is historical character.”” The Arboretum will be listed in official government 
publications of such sites but will not receive financial support, nor will 
there be any change in the joint operation of the Arboretum by the City 
of Boston and Harvard University. A bronze plaque will be placed on the 
Arboretum grounds during the next year. 


Staff: 

It is with deep regret that we report the deaths of Mrs. Susan Delano 
McKelvey on July 11, 1964, and of Mrs. Dorothy H. Marsh on April 13, 
1965. Last year we reported Mrs. McKelvey’s desire to retire from active 


466 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


service on the Committee to Visit the Arnold Arboretum and as a Research 
Associate on the Arboretum staff. Her death such a very short time later 
was unexpected. In a biographical sketch and bibliography, published in 
the Journal of the Arnold Arboretum (46: 45-47. 1965), we have recorded 
her contributions as an outstanding horticulturist. 

Mrs. Marsh worked part time as an artist on the project concerned with 
the Generic Flora of the Southeastern United States. Her illustrations of 
many of the critical genera of the area have been and will for some time 
to come be published in the continuing studies of the Flora which appear 
in the Journal of the Arnold Arboretum. The accuracy and high artistic 
quality of these drawings add immeasurably to the value of the published 
works. 


The appointment of Dr. Lorin I. Nevling, Jr., as Associate Curator, 
without limit of time, was approved during the year. Dr. Nevling serves 
as Supervisor of the Herbarium of the Arnold Arboretum and Supervisor 
of the Herbarium of the Gray Herbarium on joint and simultaneous 
appointments. 

Three new annual appointments were made during the year. Dr. 
Thomas Gordon Hartley, a graduate of the University of Iowa, has spent 
the past three years as botanist on a phytochemical survey of the native 
vegetation of Papua and New Guinea. His special familiarity with that 
vegetation will be of value in studies of our herbarium collections from the 
area. Dr. Ian Keith Ferguson, a graduate of Trinity College of the Uni- 
versity of Dublin, was appointed to work with Dr. Wood on the Generic 
Flora of the Southeastern United States. Mr. Henry Barnes Hosmer was 
appointed an honorary Research Associate. The Arboretum will gain 
much from his interest in the introduction to this country of native plants 
of Afghanistan. 

The appointment of Dr. Mary Elizabeth Sanders as a Research Fellow 
was renewed. Dr. Sanders holds the North Carolina-Sandeen Fellowship 
of the American Association of University Women. 

Mr. Arnold David Clapman has been engaged as an artist to succeed 
Mrs. Marsh on the Flora project. 

Mercer Research Fellowships for varying periods of time were awarded 
during the year to five scholars whose work would be aided by access to 
the collections of the Arnold Arboretum. Mr. Arturo Gémez Pompa, of 
the National University of Mexico and of its Botanical Garden, who came 
here as a Guggenheim Fellow, continued, as a Mercer Fellow, his work 
on the vegetation of Veracruz, Mexico. Dr. Hermanus Philippus van der 
Schijff, of the University of Pretoria, Republic of South Africa, who ar- 
rived in January, is working in the laboratory of wood anatomy on prob- 
lems of stem enlargement. Dr. Hans U. Stauffer, of the University of 
Zurich, stopped briefly to examine materials of the Santalaceae. Dr. H.- 
Christian Friedrich, of the University of Munich, studied material of the 
Aizoaceae. M. Michel Colon, a recent graduate of the Royal School of 
Horticulture at Vilvorde, Belgium, spent several months taking part in 
various operational activities of the Arboretum to become familiar with

this type of horticultural enterprise. Mr. Edward A. Murray, a graduate 
student of Pennsylvania State University, spent three months examining 
living and herbarium collections of the maples. 

We record also the departure of Dr. Lalit M. Srivastava, who held a 
Mercer Research Fellowship for three years, and of Dr. Shirley A. Graham, 
who worked for a year on the project of the Generic Flora of the South- 
eastern United States. 

Honors and assignments came to various members of the staff during 
the year. Mr. Alfred Fordham was appointed to the research committee 
of the Massachusetts Nurserymen’s Association and to the cultivar testing 
committee of the International Plant Propagators’ Society. Mr. Peter 
Green was elected secretary for a five-year term at the meeting of the 
International Association of Botanic Gardens. Dr. Howard was reap- 
pointed to the board of the Division of Botany of the International Union 
of Biological Sciences as a representative of the Section of General Botany. 
He serves as past President and a member of the board of the International 
Association of Botanic Gardens and as a council member of the Association 
for Tropical Biology. Dr. Karl Sax, Professor emeritus, served as Sigma 
Xi lecturer during a portion of the year, as visiting professor of genetics 
at Cornell University in the fall of 1964, and as Research Associate on a 
Public Health Service grant at the University of Georgia during the winter 
trimester. He was awarded an honorary degree of Doctor of Science, at 
Commencement exercises, in June, from the University of Massachusetts. 
Dr. Bernice Schubert continues as a member of the Editorial Board of the 
Bulletin of the Association for Tropical Biology. Dr. Carroll Wood was 
reappointed to the Subcommittee for Family Names of the Committee for 
Spermatophyta at the Nomenclature Section of the X International Bo- 
tanical Congress at Edinburgh. 

r. Wyman was elected President of the Horticultural Club of Boston. 
He continues as a Director of the American Horticultural Society and as 
chairman of its Awards Committee. He is a member of the organizing 
committee for the XVII International Horticultural Congress to be held 
in Maryland in 1966, and chairman of the “amateur section” of that 
Congress. During the year Dr. Wyman was honored three times for his 
horticultural writings. The International Shade Tree Conference awarded 
him an honorary membership and plaque in appreciation of his interest 
in promoting the planting and preservation of shade and ornamental 
trees. The National Council of State Garden Clubs presented him with 
a certificate of merit in recognition of distinguished service in promoting 
literary horticultural interest. Finally, the Garden Club of America Medal 
of Honor was awarded to “Dr. Donald Wyman, Horticulturist of the 
Arnold Arboretum of Harvard University, whose energy, ability and con- 
tributions to horticulture are outstanding.” 


Horticulture: 
The successful growing of plants in New England is becoming de- 
pendent on an apparently decreasing summer rainfall. Although mention

has been made of the drought conditions in previous reports, the cumula- 
tive effect of successive summers deficient in rainfall are now conspicuous 
and serious. Three of the first four months of the calendar year 1964 
exceeded the expected or mean rainfall by 10 per cent, but seven of the 


1965 | THE DIRECTOR’S REPORT 469 


following eight months were deficient. May, June, July, and August, which 
should average 13.36 inches of rainfall, produced only 5.95 inches in 1964. 
In fact, water was carried continuously in tank carts between June and 
November. Several severe fires were caused by carelessness and vandalism. 
The fall planting program was considerably restricted and was completed 
only in areas easily reached with water. The year 1965, to the date of this 
report, has been Ceficient in rain; however, the prevalence of cool weather 
with temperatures well below normal, has been of some aid in reducing 
loss of plant materials. 

The flowering season of the spring of 1965 was outstanding for crab 
apples, lilacs, and rhododendrons and much below average for cherries, 
azaleas, and dogwoods. Records of flowering density and dates of the crab 
apples have been kept for over a decade; this spring produced the heaviest 
recorded flowering. As it was also the flowering year for crab apples which 
are alternate-flowering types the display was superb. A cool dry spell kept 
the blossoms for a long period, and there appears to be excellent fruit-set. 
As it was also the best recent flowering season for lilacs, Lilac Sunday was 
enjoyed by a large number of visitors. In contrast was the poor flowering 
of most azaleas, the Ghent hybrids being the sole exceptions. In addition, 
there was a large amount of dead wood in the azaleas which can be at- 
tributed to the dry summer of 1964. 

The Department of Parks and Recreation of the City of Boston com- 
pleted the roadway to the top of Peter’s Hill during the early summer. 
This paved turnaround area provides a fine view of Boston as well as a 
good location for demonstrating the relationship between soil types and 
forest tree vegetation in the Arboretum and on adjacent properties, and 
for indicating the area of the land composing the shoulder of the Boston 

asin. 

During the spring months Mr. Seth Kelsey was retained as a landscape 
consultant in connection with certain problems and problem areas within 
the Arboretum. In accordance with his suggestions, preliminary work is 
under way in some areas of the grounds, including a section of wet land 
across from the Administration Building where a grove of Metasequoia 
has been planted, and an area of shrubbery around Bussey Hill which has 
been reduced to allow better vision and to develop a better display of 
ground cover plants. 

A preliminary effort has been made in cooperation with the City of 
Boston to clean and grade a triangular plot of land isolated when Route 1 
(Centre Street) was relocated. The excellent varieties of flowering crab 
apples on the land, which could provide a spectacular approach to Boston 
from the south, make the additional work and fencing seem justified. 

A project suggested for participants in the Job Corps training program 
proposed for the City of Boston is the reconstruction and repainting of the 
fence surrounding the Arboretum. In anticipation of this program, old 
vines growing on the fence were severely pruned during the late winter 
months. 


In the vicinity of the greenhouses, two new beds were established as

The work of the greenhouse staff includes the receipt and distribution 
of plant materials; the maintenance and service of collections, experimental 
and research projects; and educational activities. 

The records for the receipt and distribution of plant materials as seeds 
propagating material, or whole plants indicate the extent of activities. 
During the year the Arnold Arboretum staff received 288 shipments of 
plant materials comprising 1482 units from 39 countries. We sent out 294 
shipments of 1314 units to cooperating institutions and nurseries in 17 
countries. Much of the material received was collected or selected by Dr. 


well as private gardens, many new plants worthy of introduction and trial 
in the United States have been located. The acquisition of this material, 
its shipment and acceptance at ports of entry, and its subsequent quaran- 
tine status involve the cooperation and kindness of many individuals and 
organizations; we are most grateful to each of them. The full amount of 
material being introduced as a result of Dr. Wyman’s trip will be indicated 
in the annual report of the next fiscal year. Already the number of taxa 
received suggest that this will prove to be one of the major recent horti- 
cultural efforts. 

Material has also come in from a sponsored expedition to the Near East 
and from the efforts of Mr. Hosmer in Afghanistan. 

The distribution of materials from the greenhouse facility is partly in 
response to requests and partly in continuance of a program of distribution 
and testing. Hardiness testing programs in cooperation with the univer- 
sities of Minnesota, Maine, New Hampshire, and Vermont and with Iowa 
State University continue, with the resulting establishment of new orna- 
mental plants in areas previously considered unsatisfactory. In another 
program, plants are regularly contributed to the North Central Regional 
Hardiness Testing Program of the United States Department of Agricul- 
ture in Ames, Iowa. Plants used for research projects at the Arboretum 
which need warmer climates for continued growth are grown in one of 
several gardens in Florida which cooperate with us, or in one of the Gulf 
states, while new preliminary arrangements now permit limited amounts 
of material to be grown in one of three locations in Puerto Rico. 

Requests for material come from many sources and may be general in 
nature, or specific to fill particular research needs. It was possible this 
year to supply material for planting around many new University buildings 
and to fulfill small requests from some other institutions. In response to 

many requests material has been supplied to various workers for scien- 
tific studies. Fifty-seven kinds of seeds were sent to Iowa State University 
for use in an investigation of plant proteins which react with certain 
animal blood-groups. Members of the Araliaceae are still under investiga- 
tion for their cancer-retarding constituents. An investigation of the 
accumulation and retention of fluorides in plant tissues led to the request 


472 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


for leaves of members of the Theaceae. Morphological investigation in 
many parts of the world led to requests not only for specific plant parts 
but for specimens collected at definite intervals in the development of the 
flowers or fruits. 

During the year 340 taxa were propagated to serve as replacements on 
the Arboretum grounds; 107 taxa were processed to provide staff members 
with material for taxonomic work, teaching, or morphological research. 
To acquire propagation data for experimental work of the greenhouse 
staff 76 taxa were processed during the year. Experimental work on the 
propagation of witches’ brooms on conifers continues and shows consider- 
able horticultural promise. 

Progress continues on the checking of identification of plants on the 
grounds and in the preparation of new labels where they are needed. Prep- 
aration of specimens from the plants on the grounds not previously repre- 
sented in the herbarium of cultivated plants has been carried on actively, 
and additions to the collection of cultivated specimens have also been 
received from England and Switzerland, together with large collections for 
identification from Australia, Bermuda, Brazil, Iraq, and Trinidad, as well 
as the United States. Selected specimens from the greenhouse collections 
of Cornell University and of Smith College, for which we are grateful, 
were also made available. An interesting collection of specimens of cul- 
tivars of Erica and Calluna was obtained from the Heather Garden of Mr. 
H. Copeland, near Chatham, Massachusetts. 

Dr. Dudley’s introductions of many taxa of Alyssum survived the 
winter in field plantings at the Case Estates and suggest that such taxa 
from the Mediterranean and the Near East may be of horticultural value 
in New England. Mr. Green continued his work on Jasminum under 
cultivation. Many of his recent introductions, now released from post- 
entry quarantine, have been distributed to other gardens for testing. In 
connection with Mrs. Lily Rudenberg’s cytological studies on our Loni- 
ceras, Mr. Green checked the identification of much of the collection and 
made a detailed study of Lonicera tatarica, its relatives, and the associated 
mass of hybrids. A coordinated program of testing Lonicera has been 
planned with the horticulturists of the Moscow Botanic Garden. Seeds of 
many clones of Lonicera have been supplied from localities throughout the 
Soviet Union; comparable observations and data will be sent from this 
country. 

A registration list for Weigela has been completed by Dr. Howard, and 
lists for Lantana, Philadelphus and Sambucus are in preparation. 


Case Estates: 

An Open House was held at the Case Estates in Weston on Sunday, 
May 16th. Several staff members were present to explain the work in 
progress and to answer questions. The number of individual visitors and 
organized groups at such events has increased. To explain better the func- 
tions of the several plantings and exhibits and to reduce the demands on 
the staff, a brochure was prepared which, through numbers and arrows,

directs a self-guided tour. The leaflet has proven popular and has much 
increased both the number and the interest of the visitors. Engraved labels 
on all of the display plantings helped to distinguish the plantings which 
are experimental from those of established horticultural value. 

Several of the special collections of cultivars have been increased 
through the generosity of individuals and societies or organizations. The 
Hosta collection now contains the best clones selected by Mrs. Frances R. 
Williams, of Winchester, Massachusetts. Additional named clones re- 
ceived from the Botanic Garden in Uppsala, Sweden, serve to document 
the monographic work of Dr. Nils Hylander. Through the kindness of Sir 
George Taylor, Director of the Royal Botanic Gardens, Kew, selected 
clones of English origin have been received for trial. Dr. K. J. W. Hensen 
assisted in supplying the clones of Hosta from the collections of the Land- 
bouwhogeschool in Wageningen which documents the registration list of 
cultivars published in the Netherlands. The combined collections of over 
140 clones will permit a cross evaluation of hardiness and horticultural 
characteristics of plants originating in Europe and in America. 

he Hemerocallis collection has been increased by additional taxa do- 
nated by members of Region 4 of the American Hemerocallis Society. 
This collection is being developed to show students and the public the 
characteristics of the species, the variations which are the basis for horti- 
cultural classification and selection, and the best of the cultivars. 

The Lilium collection created exceptional interest locally as it came 
into flower. Dr. Wyman has maintained records of the flowering periods 
and related data which were published in an issue of Arnoldia. The inter- 
national requests for this publication indicated the very wide interest in 
lilies. We acknowledge with appreciation the gift of 400 bulbs of Liliam 
superbum rubrum ‘Uchida’ sent in furtherance of international friendship 
and as an example of the breeding and selection work being done in the 
Kanagawa Prefecture of Japan. The size of this gift has permitted the 
staff to plant these bulbs in many locations, using different mulches. 

On the basis of our observations on the small-tree plot Dr. Wyman has 
assisted a special committee of the Wire Utility Services of New England 
to revise their booklet “Trees in your community.”’ 

The tree-growth test-plantings of the Cabot Foundation in Weston were 
re-examined during the year by Dr. Scott Pauley, then cleared of volun- 
teer seedlings and dead trees and subjected to selective pruning. The 
growth rates of these plantings are compared at regular intervals with 
plants of the same clones and taxa grown in Jamaica Plain, Petersham, 
and Quabin, Massachusetts, and in Minnesota. 


Herbarium: 

Considerable progress was made in curatorial work involving the her- 
barium quarters, the insertion of mounted materials, and the organization 
of unidentified collections formerly in storage. The fourth floor of the 
Administration Building in Jamaica Plain, where part of the herbarium of 
cultivated plants is housed, was cleaned and repainted. A well-covering

1965] THE DIRECTOR’S REPORT 475 


placed between the second and third floors allows better heat control and 
reduces the noise of activities elsewhere in the building. The collection of 
unworked and duplicate collections was reorganized for greater efficiency. 
Work continues on the organization of cultivated plant specimens into the 
geographical areas where they are grown, on the recognition and marking 
of type specimens, and on the annotation of specimens representing taxa 
considered in recently published monographs. 

During the year 20,395 specimens were mounted and added to the 
herbarium collections in Jamaica Plain and Cambridge, bringing the total 
number of sheets to 806,279. During the year 10,167 specimens were re- 
ceived, the greater portion by exchange. 

During the past year staff members and students requested or received 
for identification 4,317 herbarium sheets representing 95 loans from 36 
institutions. The staff filled loan requests for 138 loans to 72 institutions 
and sent out 14,713 specimens. 

Dr. Brizicky completed his studies of the Tiliaceae and Elaeocarpaceae 
for the Generic Flora of the Southeastern United States and has turned 
his attention to the Sterculiaceae represented in that area. Studies on the 
Cistaceae and Vitaceae were the result of earlier studies for the flora 
project. 

Dr. Dudley is continuing studies on the genus Alyssum, segregates, and 
relatives and is preparing a treatment of the group for the Flora Iranica. 

Dr. Ferguson completed studies of the families Dipsacaceae, Valerian- 
aceae, and Caprifoliaceae in the southeastern United States and has turned 
his attention to the Cornaceae of the area. 

Mr. Green completed work on his collections from New Caledonia, 
Lord Howe Island and Norfolk Island. Many of these collections were 
studied at the herbaria of Kew and the British Museum during visits 
associated with the botanical congress in Edinburgh. 

Dr. Hartley began a study of Zanthoxylum, including Fagara and 
Blackburnia, in the Malesian area. His large collections from Papua and 
New Guinea have arrived, and the nearly 3700 numbers are being pre- 
pared for identification. 

Dr. Howard has continued his studies of the plants of the Lesser An- 
tilles, devoting considerable attention to old unidentified collections from 
the French Islands which have been loaned by the Muséum National 
d’Histoire Naturelle, Paris. The collections of Dr. and Mrs. Richard 
Wagner in Puerto Rico include many new records and several new species. 
Preliminary plans have been prepared for a critical study of the environ- 
ment, composition, and biology of the mossy forest zone in the Luquillo 
Mountains. 

Dr. Hu made trips to various European herbaria before and after the 
botanical congress in order to photograph and examine many of the type 
collections of species of Jlex. She has also completed and submitted for 
publication a bibliography of the Compositae of China. 

Dr. Nevling continued his studies of the Thymelaeaceae. He has veri- 
fied the hybrid origin of Daphne  mantensiana, as suggested by earlier 


476 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


studies, and completed a treatment of the Brazilian genus Funifera. 
Studies of Dirca and Schoenobiblus are in progress. The genera Decu- 
maria, Pileostegia and Schizophragma are being examined for both their 
horticultural and botanical interest. 

Dr. Perry, although officially retired, has completed the preparation of 
a manuscript on the medicinal plants of southeastern Asia and has turned 
her attention again to the Arboretum material collected in New Guinea by 
Dr. Brass and others. 

Dr. Schubert had the opportunity of examining type specimens and 
other important historical collections of the genera Desmodium, Dioscored, 
and Begonia during visits to herbaria at Edinburgh, Kew, and the British 
Museum. 

Dr. Wood has continued his direction of the work toward completion of 
a Generic Flora of the Southeastern United States. The extensive list of 
family treatments already prepared is scarcely indicative of the important 
background work also accomplished in the preparation of bibliographies, 
lists of abbreviations, glossaries, and the supervision of the preparation of 
the illustrations. Dr. Wood also studied types and critical material of 
the genus Hedyosmum at British and European herbaria before the bo- 
tanical congress. 

We are pleased to have had many visitors who examined material in 
their special groups for varying periods of time. These studies involved 
not only the herbarium and library, but also the special collections of 
fruit, wood, pollen, and the living collections in Jamaica Plain and Weston. 
Among others, Dr. Quentin Zielinski, of Oregon State University, used 
almost all the facilities for his work on the genus Pyrus; Dr. Howard 
Scott Gentry, of the U.S. Department of Agriculture, started an examina- 
tion of our material of Agave and studied the pertinent literature, as well 
as the special collections and notes prepared by Mrs. McKelvey. Dr. R. J. 
Williams, of the CSIRO of Australia, consulted with Dr. Schubert regard- 
ing Desmodium and other Leguminosae and checked specimens and distri- 
butions in the herbarium before continuing his trip for field work in South 
America. Dr. Stauffer, completing a trip around the world devoted to the 
study and collection of material of the Santalaceae, spent a month study- 
ing and annotating our material. Dr. Philip Munz used the herbarium for 
an extended period in connection with his work for the new edition of 
Hortus being prepared at the Bailey Hortorium of Cornell University. 
Mr. Dieter Wasshausen, of the United States National Herbarium, was 
one of the visitors especially interested in the methods and procedures 
used in the herbarium. 

The herbarium and library are the depository for many valuable special - 
collections. We are happy to acknowledge a particularly interesting gift 
this year of the manuscripts, specimens and fragments, and photographs 
compiled by the late Dr. Henning Horn af Rantzien in his studies of 
Potamogeton and other aquatic flowering plants. This material, the gift 
of his widow, Mrs. Anna Horn af Rantzien, will be available for the 
study of visiting scholars. 


1965 | THE DIRECTOR’S REPORT 477 


Library: 

Much of the activity of the library staff during the year concerned the 
organization and evaluation of material received as bequests and gifts, 
and of older collections needing additional work. Mrs. McKelvey, who 
knew our library as well as any individual could, enriched it still further 
by leaving 280 of her books to be added to our collection. Her earlier gifts 
of supporting materials to her work on lilacs, yucca, and the Trans- 
Mississippi West have been acknowledged in previous reports. 

Mr. Seth Kelsey, a friend of the Arboretum and a member of the Com- 
mittee to Visit the Arnold Arboretum for many years, moved from the 
Boston area and was forced to dispose of the records of his father, the 
late Harlan P. Kelsey. Since much of the material concerns the develop- 
ment of horticulture in New England, the staff of the Arboretum has 
accepted this collection for study and organization prior to appropriate 
disposition of parts of the material on national parks, city planning, 
standardized plant names, the American Horticultural Society, and the 
Arnold Arboretum. Of particular value and interest to the Arboretum 
will be the extensive correspondence of Mr. Kelsey with Charles Sargent, 
E. H. Wilson, and many other members of the staff. 

We are grateful to Mr. H. H. Richardson, to Mr. Malcolm A. Milne, 
and to others who do not wish to be named for large collections of books. 

Many books and pamphlets on plant morphology and plant anatomy 
which were transferred in 1933 to the library of the Biological Labora- 
tories have been reincorporated in the library collections of the Arnold 
Arboretum. 

Considerable effort has been devoted to reorganizing the reprint collec- 
tion of the late Professor J. H. Faull. The system of classification which 
was useful to the compiler has not proven to be a practical one for a 
modern library, making a reorganization essential. Many of the reprints 
concerned with forest plant pathology, accumulated while Professor Faull 
was on the staff of the University of Toronto were offered to the Shade 
Tree Research Laboratory of the University of Toronto and were grate- 
fully accepted. 

Miss Stephanne Sutton has undertaken the task of organizing the mate- 
rial and correspondence concerning the history of the Arnold Arboretum. 
We are requesting from other institutions “xerox” or other copies of 
letters of historical interest to and from Arboretum staff members. Mr. 
Henry de la Montagne, of the New York Botanical Garden, has been 
instrumental in supplying copies of correspondence from that institution, 
and his assistance is deeply appreciated. 

During the year 647 bound volumes were added to the library of the 
Arnold Arboretum bringing the total to 52,864. Two hundred and forty 
volumes concerning horticulture were deposited in the library in Jamaica 
Plain. We acknowledge the assistance of Mr. Theodor Mayer, of Mont- 
real, Canada, for his interest and help in adding to the Arboretum hold- 
ings of volumes on the genus Rosa. Reprints and pamphlets totalling 450 
were added to files of monographs and author separates making a total of 


478 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


20,274 items so catalogued. Many of the older reprints were placed in 
permanent covers with typed indices. 

The annual published increment of 3000 cards was added to the Card 
Index of American Plants issued by the Gray Herbarium. Sixteen hundred 
title cards were added to the Index to American Botanical Literature 
published by the Torrey Botanical Club. Number 20 of the Jndex 
Nominum Genericorum series was received and incorporated. Over 1400 
index cards appropriate to the Rehder index of cultivated plants were 
prepared and inserted in the series. 

Mrs. Schwarten has continued her work on the preparation of stand- 
ardized abbreviations for bibliographic citation. She is working with 
Mr. Green and Dr. Howard in the compilation of literature citations used 
in the registration lists of cultivar names being published. To this index 
will be added citations for nurseries and nursery catalogues which have 
proven to be sources of cultivar names. Publication is expected in this 
calendar year. 


Comparative Morphology: 

Professor Bailey is continuing his investigations on the primitive leaf- 
bearing Cactaceae under an extension of his grant from the National 
Science Foundation. At present he is concerned with the occurrence of 
“protein bodies” in Pereskia and Pereskiopsis and with the formation of 
water-soluble anisotropic bodies in dehydrated leaves of these genera. 
Papers numbered XII and XIII of the series dealing with these significant 
groups have been published during the year. 

Professor van der Schijff, since the first of the year, has been working 
in this laboratory. He has undertaken an investigation of the unusual 
growth characteristics and subterranean stem development in many of the 
Leguminosae from arid regions of South Africa. Seeds of Elephantor- 
rhiza elephantina, Erythrina burkei, Erythrina humeana, and Erythrina 
zeyheri were started in the greenhouses of the Arboretum and showed the 
same characteristics of shoot dormancy exhibited by these plants in the 
Southern Hemisphere. In its native habitat Elephantorrhiza elephantina 
may be regarded as a noxious weed because of the persistence of its en- 
larged subsurface base. A study of the seedling development of all four 
species will yield information about the origin of the characteristic 
elephantine stem forms of these plants. 

Dr. Howard has continued his studies of nodal and petiolar anatomy 
with attention devoted to securing information concerning families of 
plants not well represented in the available flora, or families of recent 
description, and genera regarded as having questionable affinities. 


Cytology and Genetics: 

Dr. Sanders has continued her studies of the cytology of various col- 
chicine treated lines of Sorghum. The investigation involves diploid 
mutants obtained from both diploid and tetraploid seedlings. Chromo- 
some counts have been made for most of two hundred untreated and

treated plants. Some diploid mutants showed cytological disturbances at 
diakinesis associated with a premature fractionation of the nucleolus. 
These will be studied for possible evidence of chromosome changes in the 
mutants. 

The development of information on the technique of germinating seeds 
of woody ornamental plants has produced many seedlings which are con- 
sidered expendable in a variety of additional experiments. Colchicine has 
been applied to a number of these to observe the nature and frequency of 
changes induced and to determine the possible horticultural value of 
plants so influenced. Seedlings of 12 species were treated with 0.5 per cent 
colchicine in lanolin and kept for seven days under 250 watts of infrared 
light at temperatures of 60 to 80 degrees F. and in high humidity. An 
equal number of seedlings without colchicine treatment were raised in the 
same environment as control plants. Following the infrared light treat- 
ment all plants were raised in normal greenhouse environment. Nearl 
every lot of untreated seedlings showed some reaction to the infrared 
light, most often the plants died. The loss was particularly severe in the 
seedlings of Cornus kousa, Magnolia obovata and Tsuga caroliniana sug- 
gesting further work on infrared effects on germination and seedling de- 
velopment is essential. The colchicine treated seedlings showed pheno- 
typic variation from stunted growth habits to plants of exceptional vigor. 
Polyploidy is suspected in five of the 12 species tested. Verification will 
come when the plants are larger and chromosome counts can be checked. 

Chromosome counts are made routinely on much of the material proc- 
essed in the greenhouses or grown on the grounds. Counts are recorded 
on voucher herbarium sheets as well as on the record cards of the taxa. 
During the year Dr. Sanders obtained a preliminary chromosome count 
from root tips of seedling Austrobaileya, the first record known to us for 
that genus. Chromosome counts were also made in association with re- 
search projects on species of Prinsepia and on the dwarf seedlings de- 
veloped from witches’ brooms of Pinus strobus. 

The existence of a triploid plant of Forsythia has been questioned re- 
cently in literature from Europe. A re-examination of all plants labelled 
Forsythia ‘Beatrix Farrand’ in our collection, as well as additional mate- 
rial received from nurseries under that name, has revealed all plants to be 
tetraploid. Since the original chromosome count was made and verified 
by competent cytologists it is possible either that only a single shoot 
showed this abnormality or that the triploid plant has been lost. Any 
suggestions of sources of the original plants distributed as triploid 
Forsythia ‘Beatrix Farrand’ will be welcomed. 

Mrs. Rudenberg has continued her cytological studies of taxa of Loni- 
cera in a systematic examination of plants in the living collections of the 
Arboretum, To the present, chromosome counts from 72 plants in 30 dif- 
ferent species have been obtained. The species of Lonicera appear to be 
predominantly diploid, 2n = 18. There are relatively few polyploids in 
the genus, yet some species have indistinguishable diploid and tetraploid 
forms. Many taxa have been counted for the first time and tetraploid

forms have been found in varieties of species previously considered diploid. 
Dr. Nevling has obtained chromosome counts from several species of 
tropical plants important to work in progress in Puerto Rico. 


Education: 

Two formal courses in Harvard College were offered by members of the 
Arboretum staff during the year. Dr. Howard taught a new course, 
Biology 209, The Phylogeny of the Flowering Plants. During the mid- 
semester vacation the class travelled to a field location in Puerto Rico and, 
with the assistance of Dr. Wood, spent a week in closer examination of 
many families limited to the tropics. In the spring semester Dr. Wood and 
Mr. Green taught Biology 103, an introductory course, The Taxonomy 
of Vascular Plants. A special financial arrangement was made with the 
Department of Biology permitting this cooperative effort. 

Graduate students, undergraduates, special students and Mercer Fel- 
lows worked with several staff members for guidance and in the develop- 
ment of special problems in taxonomy or in horticulture. Most of the 
staff attended and participated in the seminar series on plant taxonomy 
held in the Harvard University Herbarium building. 

The informal classes offered without academic credit to the general 
public were conducted in Jamaica Plain and in Weston. The fall field 
class, with emphasis on horticultural practices, was conducted by Dr. 
Wyman in Jamaica Plain. Dr. Sanders led the class in Weston, considering 
some of the cytogenetical problems of plant populations in the wild and 
under cultivation. Mr. Fordham again taught a class in plant propagation 
which met at appropriate intervals for the work to be done throughout the 
year. In the spring, the Weston field class was held on Tuesday and 
Thursday evenings between 6 and 7 P.M. interesting a different group of 
people than had come for the afternoon classes. Dr. Howard, with the 
special assistance of Dr. Hartley and Mr. Williams, was responsible for 
the classes. In Dr. Wyman’s absence, the spring field class in Jamaica 
Plain was led by members of the staff and it, too, was held at a different 
time, Saturday morning. The new audiences coming to the classes held at 
different times suggests that varying the days of the classes every few years 
may make them of greater value to a larger number of people. 

Several special programs were arranged to meet specific requests. Mr. 
Fordham conducted a workshop on the germination of woody plant seeds 
in the Dana greenhouses for guests of the Massachusetts Horticultural 
Society. Dr. Dudley participated as a guest instructor in a course offered 
and sponsored by the Massachusetts Department of Education at the 
State College in Boston. The course, entitled ‘“‘Environment for Living,” 
considered open spaces and recreational areas. Two laboratory sessions for 
the students were arranged at the Arnold Arboretum. The group hopes to 
conduct a survey of the street and park trees of greater Boston as a basis 
for recommendations for city beautification programs. 

The facilities of the Arboretum came into use for many visiting groups 
of horticulturists and nurserymen, as well as for classes from New England 


482 JOURNAL OF THE ARNOLD ARBORETUM [voL. 46 


colleges. Again this year, the judging and identification contest of the 
University of Massachusetts, the Massachusetts Department of Agricul- 
ture, and the Boston Public Schools was held in the Administration 
Building. The staff also made arrangements for the mid-winter meetings 
of the Northeastern Section of the American Society of Horticultural Sci- 
ences which were held in the Biological Laboratories.

building shown in the photograph. Jalmar photograph. 


The staff was represented at sessions of the Nomenclature Section and 
the remainder of the X International Botanical Congress at Edinburgh 
by Drs. Howard, Hu, Nevling, Schubert, and Wood, and Mr. Green. 
Dr. Sanders attended the AIBS meetings in Colorado. Drs. Howard and 
Wyman attended the meetings of the AABGA at Planting Fields Arbo- 
retum which were held in association with the American Horticultural 
Congress. The American Horticultural Society, in cooperation with Colo- 
nial Williamsburg, sponsored the annual Williamsburg Garden Symposium 
this spring. Dr. Wyman presented a program on low maintenance garden- 
ing and the plants which make it possible. Mr. Fordham attended the 
International Plant Propagators’ Society meeting at Rochester, New 
York. He spoke there and at the regional meeting of the Federated Garden 
Clubs at the Waltham Field Station. 

During Dr. Wyman’s trip to Europe this spring he has been asked to 
speak and often to describe the activities, facilities, and resources of the 
Arnold Arboretum. These meetings included those of the International

Dendrological Union, the Scottish Garden Society, and the International 
Camellia Society. 


Exhibits and Displays: 

For the first time in a number of years the Arboretum did not partici- 
pate in the Spring Flower Show of the Massachusetts Horticultural So- 
ciety. Impending changes in the physical plant necessitated commitment 
of labor and the requirements of greenhouse space for research materials 
and experiments in progress did not permit the forcing of trees and shrubs 
in time for the Spring Show. A demonstration of mulching materials 
similar to that shown at the Massachusetts Spring Flower Show last year 
was exhibited for the 19th American Horticultural Congress held in the 
Commodore Hotel in New York in September.

Open houses were held in Weston and in Jamaica Plain during the 
spring. The Massachusetts Horticultural Society, in awarding a gold 
medal to the Arnold Arboretum, requested our participation in a program 
of open gardens of award winners. For this two-day activity the staff pre- 
pared special exhibition cases, including new kodachrome transparency 
displays and demonstrations relating to plant exploration, the preparation 
of herbarium specimens, and techniques of plant identification. 

Mr. Heman Howard prepared a special set of display photographs of 
the Larz Anderson collection of bonsai of the Arnold Arboretum. The set 
of photographs, showing individual specimens, as well as the methods of 
housing and displaying the bonsai, is available on loan. During the year 
these photographs were displayed for a special exhibit of the Garden Club 
of America in the Goldsmith Civic Garden Center in Memphis, Tennessee. 

Dr. Hu prepared and exhibited a colorful demonstration concerned with

the lines of evolution in the genus //ex, the hollies, at the X International 
Botanical Congress at Edinburgh. 


Travel and Exploration: 

The X International Botanical Congress in Scotland afforded staff mem- 
bers attending the opportunity of taking part in tours to various botanical 
gardens and of visiting herbaria and botanical institutions. Mr. Green 
worked at the herbaria of Kew and the British Museum (Natural History) 
both before and after the Congress. Dr. Howard travelled to Denmark, 
Germany, France, and Belgium following the Congress, visiting gardens 
and herbaria in each country before returning to the institutions in London 


Leiden, and Brussels. Dr. Nevling received a travel grant from the Na- 
tional Science Foundation through an award committee of the American 
Institute of Biological Sciences which enabled him to observe curatorial 
procedures at the major herbaria in England and Scotland, the Nether- 
lands, and France. Dr. Schubert worked in the herbaria in London, and in 
Edinburgh during the Congress. Dr. Wood made an extensive trip through 
Europe before the Congress visiting gardens in Italy, Germany, Austria, 
France, and Switzerland and making photographs of plants to be used in 
his course in plant taxonomy. He examined material in the herbaria in

London, Paris, Geneva, and Copenhagen, and solved many problems 
which had arisen from his studies of the flora of the southeastern United 
States. 

Drs. Howard, Nevling, and Wood made trips to Puerto Rico in pro- 
grams of teaching and research. Materials for anatomical and cytological 
studies were collected as well as specimens for special illustrations. Dr. 
Howard attended a meeting of the Council of the Association for Tropical 
Biology in Caracas, Venezuela. With the cooperation of botanists of the 
Instituto Botanico materials for petiolar studies were collected in the 
Parque Henri Pittier and in the Botanical Garden. 

Mr. Hosmer was able to collect material of plants worthy of trial in the 
Boston area in several locations in Afghanistan. 

During the spring and early summer of 1965 Dr. Wyman is spending 
several months in Europe to obtain plants thought to be new to the United 
States and to be hardy out-of-doors at the Arnold Arboretum. These plants 
have been sought from the native floras, as well as in introduced and cul- 
tivated collections in botanic gardens, arboreta, private gardens, and 
nurseries. 

The Arboretum has agreed to share the expenses of several expeditions 
or to purchase herbarium collections or seeds from botanists of other 
institutions. During the year support was afforded expeditions in Turkey, 
Guatemala, Puerto Rico, South Africa, and Western Australia. 


Gifts and Grants: 

During the fiscal year 1963-64, property belonging to the Bussey Insti- 
tution was taken by the Commonwealth of Massachusetts by right of 
eminent domain. On this property were the old buildings forming the 
greenhouse complex of the Arnold Arboretum. The value of the buildings 
alone was credited to the Arboretum shortly before June 30, 1964, when 
the sum of $14,806.69 was added to the principle of the Bussey Fund for 
the Arnold Arboretum (1903), for that portion of the net proceeds of the 
Bussey Institution land settlement. This transaction was not recorded in 
sufficient time to be included in the Director’s Report of the appropriate 
fiscal year. 

The Friends of the Arnold Arboretum renewed their gifts during the 
year, and these funds were assigned as usual to an account for work on the 
grounds in Jamaica Plain or for activities in the horticultural department 
and the greenhouses. We are grateful for the generous and loyal financial 
support of the Friends for the work of the staff. A record of the gifts is 
published quarterly in the “Gifts to Harvard,” and the complete fiscal 
review is published annually in the Financial Report to the Board of 
Overseers of Harvard College. 

Gifts of materials for the horticultural collections, the library, the 
herbarium, or special research purposes were many and have, in general, 
been noted in the appropriate section of this report. Special gifts included 
a collection of orchid plants from Mr. and Mrs. Robert Preston for research 
projects and for teaching; a number of plants or propagation materials

Publications: 

Four numbers of the Journal of the Arnold Arboretum were issued dur- 
ing the fiscal year under the editorial direction of Dr. Schubert. The 
numbers contained 462 pages and 21 articles, primarily by members of the 
staff. We welcome the first half of the series of letters from Charles 
Sprague Sargent to the Louisiana botanist, Reginald Somers Cocks, which 
have been edited by Professor Joseph Ewan of Tulane University. Publi- 
cation of the remainder of the series of letters will be in the current volume 


volumes comprising Urban’s Symbolae Antillanae was prepared by Miss 
Sutton and Miss Carroll. It will be published in August by the Arboretum. 
An encyclopedic bibliography of the medicinal and poisonous plants of

southeastern Asia was completed by Dr. Perry and is being considered by 
a private publisher. 

Since volumes 1-10 of the Journal of the Arnold Arboretum have long 
been out of print and the supply of many single numbers has been ex- 
hausted, the available back numbers were sold during the year to the 
Kraus Reprint Corporation, 16 East 46th Street, New York, N.Y. 10017, 
under a contract to reprint the first twenty volumes and all out-of-print 
numbers, and to offer all for sale. 

The bibliography which follows lists 76 articles and books by members 
of the staff which were published during the past fiscal year.
