FORTY-FIRST ANNUAL REPORT OF THE DIRECTOR
Gentlemen:
I have the honor to submit herewith the forty-first annual
report of the Director.
Any one engaged in attempting to grow plants out of doors
realizes what a factor the weather is in the success or failure
of his efforts. While no one ever expects the weather in this
climate to be ideal, during the growing season at an institution
like the Garden the fluctuations come to be regarded as part
of the ordinary routine which must be counteracted in the
best way possible. It is not uncommon to read in reports
from other institutions such statements as ‘‘The atrocious
weather of the last two weeks has had a most disastrous effect
on plants,’’ but only when exceptional storms do unusual dam-
age is it necessary that more than this be said. The snow
storm of May 2, 1929, falls in this class, since the damage to
trees and particularly to shrubs and herbaceous plants was
very great, even exceeding that from the eyclone of Septem-
ber, 1927. Coming at a time when many plants were in full
leaf, the heavy snowfall caused a type of damage quite
unusual. Small plants which are ordinarily uninjured by
storms were, because of the weight of the snow, snapped off
at the ground, and no eatastrophe which the Garden has ever
suffered has caused so much damage to the smaller woody
and ‘herbaceous material. Trees likewise suffered, hundreds
of them losing branches, in some cases the tops being broken
out so as to disfigure them badly. The greatest loss was from

Prof. G. H. Bretnall, accompanied by his class in botany,
of Christian College, Columbia, Mo.; Dr. Carl G. Deuber,
instructor in plant physiology, Yale University ; Mr. Edward
L. Evinger, of the Bureau of Plant Industry, U. 8. Depart-
ment of Agriculture. Out-of-town botanists also have the
privilege of borrowing books on the interlibrary loan plan,
and during the year 109 such loans were made to 28
institutions.
New Accessions.—Quite a feature of the Garden’s acces-
sions in 1929 was the collection of old horticultural literature
which Mr. Gurney Wilson, the European representative, was
able to obtain from time to time in England. Also the book
catalogues have been listing some unusually desirable things,
and recently several old Floras and a work on Mosses for
which the Garden has been searching for years was ordered
from a foreign dealer. Some of the important books obtained
in 1929 were Roseoe’s ‘‘Monandrian plants,’’ published in
1828, Patouillard’s ‘‘Tabulae analyticae fungorum,’’ and
Wizlizenus’ ‘‘Memoir of a tour of northern Mexico connected
with Col. Doniphan’s Expedition.’’ Some modern works of
particular interest were the following: Cram, Modern loose-
leaf atlas; Druce, Flora of Oxfordshire; Farlow and Burt,
Iecones Farlowianae; Hough, American woods, pt. 14; Index
Londinensis; Proceedings International Congress of Soil
Science, 2 vols.; Inzenga, Funghi Siciliana; Lemée, Diction-
naire descriptif et synonymique des genres de plantes phan-
erogames; Mayo Foundation Lectures on Plant Physiology
and Pathology; Meisel, A bibliography of American history,
Vol. 3; Morris and Eames, Our wild orchids; Seymour, Host
index to the fungi of North America; Turrill, Plant life of
the Balkan Peninsula; a reprint of Van de Pass, Hortus
Floridus; Wilson, China, mother of gardens; and Walcott,
North American wild flowers, Vol. 5. Due to the failure of
a foreign publisher, some of the foreign continuations were
not received in 1929. When this was discovered every Gar-
den continuation was checked, and the missing parts written
for. Many books and pamphlets, as well as serials, were
received during the year in exchange for the Garden pub-
lications.
Garden Publications —The four numbers of Volume XVI
26 MISSOURI BOTANICAL GARDEN BULLETIN
of the ANNALS were issued in 1929. The volume is unusually
large, containing 519 pages, 42 plates, and 31 text-figures.
Eleven institutions were added to the ANNALS exchange list
during the year, of which 1 was in Russia, 1 Poland, 2 Ger-
many, 2 China, 1 Japan, 1 Canada, and 3 the United States.
Volume XVII of the monthly BULLETIN was completed, with
167 pages and 39 plates. A new catalogue of the water-lily
plants on sale by the Garden was also published in 1929.
The Garden has continued to receive an increasing amount
of publicity not only from the local press, national and inter-
national news reels, ete., but from a variety of periodicals.
In order to give some idea of the scope of the publicity outside ©
of St. Louis, the names of some of the magazines which have
printed either articles from the BuLuerin, original matter,
or extended notices of the Garden, are listed:

Statistical Information.—There have been donated to the
library or received in exchange during the year 519 books
valued at $1053.10, and 1036 pamphlets valued at $624.40.
Three hundred and ninety-five books were bought at a cost
of $2083.65, and 283 pamphletsvat a cost of $411.95. Seventy-
six volumes were sold for $485,00, and 147 books and pam-
phlets were discarded. The library now contains 44,810 books
and 68,540 pamphlets. There are also 331 manuscripts val-
ued at $1614.80 and 972,862 index cards valued at $11,582.22.
A total of 9439 cards was added during the year, of which
1315 were written by Garden employees and 8124 were
bought at a cost of $158.35. Three hundred and sixteen books
were bound and 275 were repaired.

SOME FACTS ABOUT THE GARDEN
The Missouri Botanical Garden was opened to the public by Mr.
Henry Shaw about 1860. From that date to the death of Mr. Shaw,
in 1889, the Garden was maintained under the personal direction
of its founder, and, while virtually a private garden, it was,
except at certain stated times, always open to the public. Although
popularly known as “Shaw’s Garden” the name Missouri
Botanical Garden was designated by Mr. Shaw as its official title
and in his will or in any of his writings he specifically referred
to it as the “Missouri Botanical Garden.” By a provision of
Mr. Shaw’s will the Garden passed at his death into the hands
of a Board of Trustees. The original members of the Board were
designated in the will, and the board so constituted, exclusive of
certain ex-officio members, is self-perpetuating, By a further pro-
vision of the will, the immediate direction of the Garden is vested
in a Director, appointed by the Board of Trustees. The Garden
receives no income from city or state, but is supported entirely
from funds left by the founder.
The city Garden comprises 75 acres, where about 12,000 species
of plants are growing. There is now in process of development a
tract of land of over 1,500 acres outside the city limits which is to
be devoted to (1) the propagation and growing of plants, trees and
shrubs, designed for showing either indoors or outside, at the city
Garden, thus avoiding the existing difficulties of growing plants in
the city atmosphere; (2) gradually establishing an arboretum as
well as holding a certain area as a forest reservation, with the idea
that possibly at some future time this may become the new botani-
cal garden.
The Garden is open to the public every day in the year, except
New Year’s Day and Christmas—week days from 8:00 a. m. until
one-half hour after sunset; Sundays from 10 a. m. until sunset.
The main entrance to the Garden is located at Tower Grove ave
nue and Flora place, on the Sarah car line (No. 42). Transfer
south from all intersecting lines. The Garden may also be reached
by Bus Route No. 12, to which all other motorbus lines transfer.

THE GROWING OF ORCHIDS FROM SEED
Orchids, in the minds of many people, are represented by
those tropical flowers, mostly from South America, which
are some shade of lavender, and are of relatively large
size,—the flowers of the well-to-do. This is true in some
cases, although a large number of tropical species from South
America, Africa, and the Asiatic regions are inconspicuous
and indeed may not even be recognized as belonging to the
orchid family. For the true lover of orchids there is no neces-
sity of going to the tropics, since during the months from
spring until fall he may make an excursion to neighboring
woods or meadows and there have the good fortune to dis-
cover, if they have not previously been exterminated by van-
dals, the pink lady-slipper, the snake-mouth, or the white or
purple fringed orchid. Occasionally in the late summer months
the rattlesnake plantain, with its clusters of delicate flowers
lifted on slender stems above the beautifully mottled leaves,
will reward the orchid lover’s walk. Since home products
are often little appreciated, or because wild orchids are not
produced in the winter months when our desire for the most
beautiful in the form of plant life is difficult to satisfy, the
orchid greenhouse becomes a sort of earthly paradise.
In going through the greenhouses at Gray Summit (pl. 8),
where plants are growing luxuriously, or viewing the magnifi-
cent flowers at the annual orchid show, it is difficult to realize
the obstacles which frequently discouraged pioneers of the
early nineteenth century and which to-day prevent many en-
(29)
30 MISSOURI BOTANICAL GARDEN BULLETIN
thusiasts from attaining the success they desire. The large
orchid flowers of lavender, white, yellow, or intermediate
shades, in such great demand by the orchid collectors, were
originally obtained from the tropics where they grew at almost
inaccessible heights on the trees in little-frequented regions.
Thus few people had seen these plants in their natural en-
vironment, and this fact added to the difficulty of the early
growers.
At the time when orchid growing was truly horticultural
pioneering, attempts were made to grow species, which were
subsequently found to be epiphytic or tree-inhabiting, in the
same manner as terrestrial species. This inevitably resulted
in the death of the plants. Sir Joseph Banks, the famous
English traveler and explorer, noticing that the plants grew
on trees where they obtained a free circulation of humid air
and only a little food material in the nature of decomposed
leaves and washings from the upper parts of the trees, at-
tempted to grow the plants in individual wicker baskets sus-
pended from the roof of the greenhouse. His experiments
were partially successful, and little by little improvements
were made on this method. In 1841 Paxton devised the plan
of fastening the plants to a piece of wood by means of a brass
wire, placing a little moss around the roots to furnish perma-
nent moisture. While this method was used by him in the
Duke of Devonshire’s greenhouses, nevertheless there con-
tinued to be a number of failures. At this time it was thought
that all plants coming from the tropics and near the equator
were accustomed to a uniform climate of considerable heat,
but Lindley, in 1830, pointed out that there was the addi-
tional factor of high humidity to be considered. Consequently
it became the practice to grow the plants under conditions of
high heat and high humidity, but even then some plants fell
by the wayside.
The reason some plants thrived and others perished was
finally explained in 1835, when Joseph Cooper, the gardener
of the Earl of Fitzwilliam, discovered that some orchids were
being suffocated in the air-tight and too-warm greenhouses,
a fact that was amply substantiated by the observations of
various explorers in the tropics of different parts of the world.
Thus it was noted that in such widely separated places as the

Peruvian Andes, the Khasia Hills in India, and the mountains
of Java, even at the higher elevations where snow sometimes
fell, beautiful orchid flowers were found. At last the reason
for the lack of success in the culture of certain species of
Cattleya and other genera was explained, and as a result
greenhouses were soon divided into three categories, namely,
the hot house, the temperate house, and the cool house. With
the perfection of cultural methods and the corresponding in-
crease in successful growers, there arose at the end of the
nineteenth century a great demand for orchid plants and these
were imported extensively by collectors in out-of-the-way
places. Advantage was taken of the natural resting period of
the plants during the dry season to send them back to the hor-
ticultural establishments of Europe, especially of England.
Here they arrived in large numbers, actually or apparently
dead. An occasional rare or exceptionally beautiful form was
recognized among the survivors of the multitude, and these
were eventually to become the parents of the exquisite and
highly developed hybrids of to-day.
At first all attention was directed to the cultivation of the
wild orchid species or natural hybrids, but Man was not for
long content with Nature’s efforts, for as early as 1856 the
first artificial hybrid made its appearance. It was a cross-
between Calanthe Masuca and Calanthe furcata and was
named Calanthe Dominyi in honor of its originator, Dominy.
Three years later Dominy produced Cattleya Dominiana by
crossing Cattleya maxima and C. intermedia. This appears
to be the first Cattleya hybrid. The first hybrid Cypripedium
to flower was also a cross made by Dominy, and this was ap-
propriately named Cypripedium Harrisianum, for Dr. John
Harris, a surgeon who pointed out to Dominy the feasibility
of hybridizing orchids. A succession of hybrids followed,
produced by Dominy and his successor, Seden, in the Veitch
establishment in England. Later others carried on the work,
not only crossing Cattleyas but species of other genera, such
as Laelia, Cypripedium, Dendrobium, and Masdevallia, to say
nothing of crossing two related but distinct genera. The mul-
tiplication of hybrids has taken place at such a rapid pace
that a filing system is needed to keep abreast of the times,
there being something like 8500 registered hybrids all created
32 MISSOURI BOTANICAL GARDEN BULLETIN
by the orchid breeder. Up to the present time, American
orchid growers have been far behind Europe, and especially
England, in the production of hybrids.
The orchid family is divided into a large number of genera
which comprise somewhat over 15,000 species, and yet each
year, as new and even more inaccessible regions are explored
and our knowledge increases, new species are being added. A
great number of the flowers of orchid species are of only
average beauty, while a considerable number, to one of criti-
eal taste, are inferior and unworthy of further cultivation.
Only very rarely is an individual flower discovered that pos-
sesses great floral beauty. The species, furthermore, are very
similar in coloration and, however beautiful, are monotonous
when cultivated in large numbers. The orchid hybrid is, in
a sense, a creation having no counterpart in nature, possess-
ing exceptional size, beautiful form, and entirely different
and marvelous colors. The reason for this, providing the
erosses are intelligently made, becomes obvious when it is
realized that the hybridizing of allied species or even allied
genera gives greater chances for variation in the resulting
offspring. This is most clearly shown in the horticultural
genus Potinera which combines the characters of Brassavola,
Laelia, Cattleya, and Sophromtis.
As a result of all this work, there are today, in addition
to the popular lavender color, varieties with a wide range of
very deep lavenders and intense purples, blue-lavender,
bronze, orange, light and dark yellow, saffron, flesh tints, pink,
pure white, and white with richly colored lips. Not only have
the colors been somewhat changed or blended, but the shape
has also been altered. In the wild species the petals are not
infrequently narrow and strap-shaped, or if they are broad
have some objectionable trait, such as recurving or drooping,
or lack of texture. This last character, if it be transmitted
to the hybrid offspring, makes the flower short lived. The
commercial growers, in addition to requiring flowers that last,
desire plants of great vitality that are easily grown and which
possess the free-flowering habit. Those who grow orchids as
a hobby, while recognizing the value of the preceding char-
acteristics, aim also for perfection in form. To fulfill the
requirements, the flowers should not have a spidery appear-

ance. The petals should be so arranged as to fill the spaces
and thus balance and make a symmetrical background for
the ornamental and frequently brilliantly colored lip (pl. 3).
To approach perfection in the offspring, the selection of
both parents, as has already been intimated, is of utmost im-
portance, since in many cases-undesirable traits appear to
be dominant while surpassing beauty is recessive and occa-
sionally may be lost unless reinforced by the other parent.
For example, it is recognized that certain parents take on
or impart color more readily than others, while still others
take on or impart poor form or poor lasting quality. Occasion-
ally, when comparatively mediocre stock is used for hybridiz-
ing, surprising results are obtained, due probably to the out-
cropping of recessive factors, but nevertheless a great propor-
tion of success is to be expected when parents of finest quality
are selected. With multi-generic hybrids, the chance for sur-
prises is greatly increased, and this is what adds zest and
fascination to the game of raising orchids from seeds. A
parallel may be drawn from animal breeding. For example,
in breeding race-horses, one would not go into a pasture and
choose indiscriminately the parents of a future Derby winner.
The chances are that instead of a Man 0’ War, a Spark Plug
would be the outcome. However, the horse fancier has an
advantage since the result of his breeding experiment becomes
evident in two or three years, while the orchid grower must
often wait six or seven or even ten years.
From the beginning of fertilization, approximately one year
is required to obtain the mature seed pod (pl. 4), but the time
may vary from six to eighteen months, depending on the
species involved. Not infrequently, after the pod has matured,
it will be found to contain nothing but sterile seed or chaff.
The percentage of fertile seed, for some unknown reason,
varies, even with the same parents, although there appears
to be a positive correlation with the complexity of the crosses.
The resulting fertile seeds are very minute (pl. 2), something
like 30,000 being required to weigh as much as a single grain
of wheat. The embryo contains very little reserve food mate-
rial—insufficient to permit the seedlings to become well es-
tablished unless the environment is most favorable for germi-
nation and growth. It is therefore evident that environmental

factors are important in determining the distribution and
occurrence of the species in nature. Probably not more than
one in a million of the seed produced results in a mature
plant. Under artificial cultivation it is even more important
that favorable conditions be maintained.
The early history of raising orchids from seed is full of
more or less accidental discoveries. As a result of a series of
scattered observations it became the custom to sow the seeds
at the base of the parent plant, for it was evident that seeds
thus sown germinated far better than those sown on a similar
substratum that had not been in contact with the parent. The
significance of these results was not appreciated until the
end of the nineteenth century, when Wahrlich called attention
to the fact that the roots of five hundred representatives of
the orchid family, taken at random, all contained a fungus.
Later Noel Bernard, who had made unsuccessful attempts to
germinate the seeds of Neottza, the bird’s-nest orchid of Eu-
rope, discovered during one of his field trips that the seed
capsules of this species bent toward the ground and discharged
the seeds upon the soil in the vicinity of the parent plant.
These seeds had germinated and later when examined in the
laboratory were found to be infected by a fungus. The pres-
ence of the fungus seemed to explain the relatively frequent
success of the old method of germinating the seed in the vicin-
ity of the parent.
The next step was to attempt to isolate the fungus, but this
did not meet with immediate success. Although a fungus
was isolated by Bernard and others, it was subsequently shown
by Gallaud in 1894 to be not the true orchid fungus, but one
not involved in the germination of the orchid seed nor in the
welfare of the mature plant. After the publication of Ber-
nard’s paper, a controversy arose as to the necessity of the
fungus. Some persons claimed to have had success without
it, but when such cases were examined carefully it was found
that only those seed germinated which had become infected
by the fungus. It was later disclosed that those who had
claimed success without the fungus had in reality infected
the composts with the fungus from the roots. Thus the hit-
or-miss fashion of sowing seeds at the base of the parent plant
was succeeded by the method of sowing seed on Turkish towel-

ling or burlap that had been stretched over the surface of
compost containing orchid roots. This method is often used
to-day, even though the seedlings are liable to contamination
by highly destructive fungi.
While Gallaud was the first to isolate the true orchid fungus,
Bernard in 1903 led the way in the successful germination
of orchid seeds in the presence of the fungus, on artificial
media and in flasks, Later, in 1909, Hans Burgeff published
the results of his successful experiments in which he employed
essentially the same methods as Bernard. The use of flasks
was a distinct advance over the old methods, since attacks by
parasitic fungi and insects were avoided and the air about the
seedlings could be maintained at a more even degree of
humidity.
In recent years another method, known as the asymbiotic
method of germination has been developed by Knudson and
others. It receives its name from the fact that seeds are suc-
cessfully germinated without the aid of fungi. This is in
contrast to the symbiotic method in which fungi are employed.
As a result of this development, two contending schools have
arisen—the one claiming that the presence of the fungus is
not necessary ; the other contending that although the fungus
is not necessary when proper sugars and other nutrient ma-
terials are supplied in sufficient quantities and in the right
proportion, nevertheless the seedlings grow more rapidly and
are more robust when the fungus is present. Furthermore,
this second school believes that the symbiotic method more
nearly duplicates the natural process. Which school may
eventually prove to be correct remains for the future to de-
cide, but it seems that if logical conclusions be derived from
the ample evidence of many experiments and observations
in the field, the symbiotic relation of fungus and host is a
foregone conclusion.
In the work at the Garden, both methods are employed.
The minute seeds are sown in flasks upon a specially prepared
jelly containing nutritive salts. When the symbiotic method
is used germination becomes evident within three or four
days by the seeds turning green. The first leaf and a lux-
uriant growth of hair roots develop within one to three
months (pl. 6, upper figure). The seedlings are then trans-
oo
36 MISSOURI BOTANICAL GARDEN BULLETIN
planted to another flask where they are allowed to remain
until the root system is well established (pl. 5). This requires
from five to six months. They are next potted in fern fibre
in one-inch pots (pl. 7), carefully watered, kept in a humid
atmosphere at a suitable temperature, shaded from the direct
rays of the sun, and sprayed to discourage attack by insect
pests and infection by fungi. At this critical period, the per-
centage of loss is about one per cent. After the seedlings
outgrow the one-inch pots they are transplanted into a suc-
cession of larger ones (pl. 8) at varying intervals until at the
age of six to ten years the plants mature and bloom, at which
stage they are usually in five-inch pots.
The asymbiotic method, while having its use under certain
conditions, is much slower than the preceding method. Ger-
mination takes place, instead of within three to four days,
only after ten days to six weeks, depending on the species or
varieties from which the seeds are obtained. However at no
time during the first two to three years of growth do these
seedlings become as vigorous as do those grown by the symbi-
otic method. The root system is slow in developing and the
percentage of fatalities upon removal from the flask is gen-
erally very high.
Success in growing orchids from seeds, or even in growing
the mature plants, depends largely upon the amount of care
given to the plants. Over-enthusiastic beginners frequently
make the mistake of killing the plants by kindness, which
may be evidenced by too much watering, too little or too
much sunshine, or other factors. Only through experience
and continued observation can the requirements of the plants
and an understanding of their needs be learned.

CONTROL OF THE BAGWORM
In the March, 1921, BuLuerin there appeared an article
under the title ‘‘Bagging the Bagworm’’ which gave direc-
tions for controlling this pest. This number of the BULLETIN
has long been out of print but the demand for information
concerning the bagworm is great enough to warrant reprint-
A a ye ae Le Gree ss: Daa)
MISSOURI BOTANICAL GARDEN BULLETIN 37
ing the major portion of the article, bringing it up to date
in so far as remedial measures are concerned.
While the bagworm has been more or less prevalent in St.
Louis for a number of years, the unusual number of these
pests last spring, with the resulting cocoons, makes it prob-
able that a considerable amount of damage to the trees may
be anticipated during the coming season unless some syste-
matic campaign is devised against them. The curious habit
of the caterpillar of crawling about in a bag-like case makes
it unusually conspicuous, and there are few trees in the city
on which a careful inspection will not reveal, attached to the
twigs, the old female bags, within which are the eggs for this
spring’s crop of caterpillars. The bagworm is often the most
serious leaf-chewing pest of ornamental evergreens, attack-
ing also nearly all of the deciduous trees and shrubs.
Immediately upon the hatching of the eggs the young cater-
pillar makes its way to the nearest leaf, where it begins to
feed and construct a bag for itself. This bag consists of
small fragments of leaves and bits of twigs held together by
a large amount of silk spun by the caterpillar. The construe-
tion of this bag by the young larva is extremely interesting
and well worth observing. Because of the soft body of the
larva, the protective bag is needed throughout its existence,
and as the caterpillar grows the case is constantly enlarged.
About the end of August the caterpillar completes its growth
and the bag is promptly attached to a twig. Additional layers
of silk are spun within the bag, forming a cocoon, and here
the transformation to the pupal stage takes place. In about
three weeks after the cocoon is formed the male moth emerges
from the base of the bag and flies about seeking the female.
The female moth never leaves the bag entirely, although the
head emerges from the lower end. Fertilization takes place
within the bag, after which the female gradually works her
way back into the chrysalis, which she then nearly fills with
eggs. After accomplishing this the female forces her body
through the opening in the bag, falls to the ground and dies.
Damage.—While the chief damage from this worm is of
course the defoliation of the tree, an investigation of the
effect of the construction of twigs by the bagworm, published
in the Seventeenth Annual Report of the Missouri Botanical
38 MISSOURI BOTANICAL GARDEN BULLETIN
Garden by Dr. Hermann von Schrenk, showed that the pres-
sure exerted by the silken bands on twigs of coniferous trees
was sufficient to cut off the food supply and that practically
no growth took place in the twig on the sides below the bands.
The portion of the twig above the band continued to grow
for a considerable period, but that ultimately considerable
damage might occur in coniferous trees seemed to be prob-
able. In the hardwood trees investigated, with the exception
of the locust, the pressure of the band was never great enough
to obstruct the passage of elaborated food material. The
strength which some of these bands showed was very consid-
erable. The growth energy exerted by the twig, necessary
to burst the band, of course varied very much with the
strength of the individual band, but actual measurements
showed that as high as 162 atmospheres was exerted in one
case, and it is probable that in many eases at least from 30
to 40 atmospheres pressure was produced.
Collecting the Bags.—Since the eggs of the caterpillar are
carried over the winter in the bag, the collection and destruc-
tion of these bags before the time of hatching is the most
natural method which suggests itself of eradicating the worm.
On small trees which can be thoroughly gone over with the
aid of a short ladder, or by the use of a light pole pruner,
such a method is recommended, provided all of the bags can
be removed. However, unless this can be accomplished for
all the trees, both large and small, over a very considerable
area, results may be more harmful than beneficial, for the
reason that at the time the eggs of the bagworm are destroyed
the natural enemies of the caterpillar are likewise obliterated.
Various flies which breed within the bag of the bagworm are
parasitic upon the caterpillar and under favorable conditions
are a very important factor in preventing the rapid spread
of this pest. Consequently everything should be done to
encourage the growth of the parasites. Of course, if only
a small number of the bags is collected, the beneficial para-
sites which are destroyed might have ultimately been more
effective than the elimination of comparatively few bagworm
eggs. It is therefore advisable to keep the hand-picked bags
in some sort of a receptacle instead of burning them. If a
barrel is used for this purpose it should be covered with a
pe ee ee
mayor?
MISSOURI BOTANICAL GARDEN BULLETIN 39
wire netting which will confine the caterpillars as they hatch
out but will permit the numerous parasites to escape and
be ready to assist in the control of the bagworms the following
year. In general, then, the collecting of the bags is effective
only where a comparatively few trees are infected, and it is
not likely to be of much benefit when the pest is so widespread
as it was in St. Louis during the past season. A striking ex-
ample of the futility of this method is given by the late Pro-
fessor C. V. Riley. He stated that for two consecutive months
he worked attempting to keep a single cedar tree, not more
than six feet high, free from caterpillars. Almost every day
he found fresh specimens which he had overlooked at the pre-
vious visit, and he estimated that this prodigious number of
caterpillars was the progeny of not more than two females.
Spraying.—Wherever appliances, capable of reaching all
parts of a tree, whatever its size, are available, there is no
question but that the use of some arsenical spray offers the
only adequate means of combating the bagworm. If carefully
carried out spraying will result in the destruction of all the
bag-manufacturing caterpillars so that in the following win-
ter there will be no bags to collect. Paris green has been used
with good effect for this purpose, but powdered arsenate of
lead, because of its great adhesiveness which prevents its
being easily washed off by rains, is the poison generally
employed. Any standard, well-known brand will be found
satisfactory provided it contains not more than .05 per cent
of water-soluble arsenic. Larger amounts cause burning of
tender foliage.
When mixing a spray for a few trees or shrubs it is advis-
able to follow the maker’s directions on the label, remember-
ing to use the maximum rather than the minimum as sug-
gested, especially if the caterpillars are nearly full grown.
Most brands of arsenate of lead will give good control if one
pound is mixed with each twenty gallons of water. To this
solution should be added either calcium ecasenite or a miscible
oil, obtainable at local seed companies (one gallon to two hun-
dred gallons of water), to insure even distribution and adher-
ence of the poison. The kind of sprayer, the season, and the
efficiency of the operator, will all affect the amount of mate-
rial necessary for any tree or shrub. Sufficient arsenate of
ake
40 MISSOURI BOTANICAL GARDEN BULLETIN
lead should be purchased to permit refilling the sprayer tank
again and again until the trees or shrubs have been entirely
covered. For medium-sized shrubs perhaps one-half gallon
each will be enough. A tree ten feet high, having a spread
of ten feet, may require three gallons. Later in the season
these amounts may be doubled. In using a small hand-pump
enough pressure should be maintained to produce a fog-like
mist. Much more beneficial results can be obtained with this
mist spray; a coarse spray forms heavy drops which run off.
Both upper and lower surfaces of every leaf should be cov-
ered to give effective control.
Time of Spraying.—Owing to the great variation in the
time at which trees leaf in different seasons, it is impossible
to give any definite date on which the spraying should begin.
The best rule is to begin to spray as soon as possible. after the
pest is first noticed. Much less spray is needed when the
leaves are small and the young caterpillars are more quickly
killed. Furthermore, it is extremely desirable to destroy the
pest before serious damage to the young foliage is done. The
amount of arsenic necessary to kill a full-grown caterpillar
apparently varies greatly. It has been estimated, however,
that a quantity of the powder equal to 1/4000 of the body
weight of the caterpillar will stop its feeding in an hour or
two and kill it in a few days. Even though poisoned eater-
ae appear to recover, they often fail to pupate success-
ully.
SPRING COURSE IN GARDENING FOR AMATEURS
The success of the special courses in gardening for amateurs
in 1929 warrants the offering of a new course this spring.
The following outline indicates the general content of the
course although changes may be made later to meet the spe-
cial needs or desires of those constituting the class. The work
will consist of talks, demonstrations and, as far as may be
possible, the actual use of plant materials. While the course
may be regarded as elementary, it is hoped that any who
took the work last year will be able to find enough that is
new to warrant their joining the course for the second season.

SOME FACTS ABOUT THE GARDEN
The Missouri Botanical Garden was opened to the public by Mr.
Henry Shaw about 1860. From that date to the death of Mr. Shaw,
in 1889, the Garden was maintained under the personal direction
of its founder, and, while virtually a private garden, it was,
except at certain stated times, always open to the public. Although
popularly known as “Shaw’s Garden” the name Missouri
Botanical Garden was designated by Mr. Shaw as its official title
and in his will or in any of his writings he specifically referred
to it as the “Missouri Botanical Garden.” By a provision of
Mr. Shaw’s will the Garden passed at his death into the hands
of a Board of Trustees. The original members of the Board were
designated in the will, and the board so constituted, exclusive of
certain ex-officio members, is self-perpetuating. By a further pro-
vision of the will, the immediate direction of the Garden is vested
in a Director, appointed by the Board of Trustees. The Garden
receives no income from city or state, but is supported entirely
from funds left by the founder,
The city Garden comprises 75 acres, where about 12,000 species
of plants are growing. There is now in process of development a
tract of land of over 1,500 acres outside the city limits which is to
be devoted to (1) the propagation and growing of plants, trees and
shrubs, designed for showing either indoors or outside, at the city
Garden, thus avoiding the existing difficulties of growing plants in
the city atmosphere; (2) gradually establishing an arboretum as
well as holding a certain area as a forest reservation, with the idea
that possibly at some future time this may become the new botani-
cal garden.
The Garden is open to the public every day in the year, except
New Year’s Day and Christmas—week days from 8:00 a. m. until
one-half hour after sunset; Sundays from 10 a. m. until sunset.
The main entrance to the Garden is located at Tower Grove ave.
nue and Flora place, on the Sarah car line (No. 42). Transfer
south from all intersecting lines. The Garden may also be reached
by Bus Route No. 12, to which all other motorbus lines transfer.

OLD VIBURNUM IN NEED OF RENEWAL PRUNING.
Shoots at “.\" to be removed the first spring, those at “B” the following year.
Missoun Botanical
Garden Bulletin
Vol. XVIII MARCH, 1930 No. 3
THE PRUNING OF ORNAMENTAL TREES
AND SHRUBS
The removal of any growth from a tree or shrub might be
considered pruning; yet many distinct kinds may be recog-
nized. Some pruning is adapted to shrubbery only, some to
ornamental trees, still other kinds to fruit trees and bush
fruits. Then there is topiary work in formal gardens and
lastly ‘‘tree butchery.’’? This article is concerned chiefly with
the pruning of ornamental trees and shrubs.
Success in pruning will be proportional to the gardener’s
ability to co-operate with Nature. In every group planting
the individuals are constantly struggling for light and food,
and when the buds are shaded by their faster growing neigh-
bors they cannot obtain light and food and consequently die.
The same competition exists between the buds on the branches,
and usually but one or two survive to continue the growth of
a particular branch. A tree or shrub produces many more
buds than ean ever grow into mature branches. The majority
remain undeveloped and grow only when an emergency arises,
but each single bud is capable of reproducing an entire plant
if necessary. This ‘‘shading out’’ is Nature’s way of prun-
ing—a method which has produced the giants of our forests.
Cultivated ornamentals cannot be permitted to follow such
a method. The ‘‘specimen’’ tree or shrub on a lawn will
have many lower branches nearly touching the ground. If
planted in a group, it must accommodate itself to the limited
space, and may not have one branch near the ground.
Before attempting to prune, allowance must be made for
(45)
46 MISSOURI BOTANICAL GARDEN BULLETIN
this constant struggle. Consideration should be given to the
age and vigor of the plant, the available moisture and food,
the presence of buildings or other trees and shrubs which
might shade it, and especially the pruning which it has already
received. No hard and fast rule ean be given for the pruning
of any particular shrub because of the many varied condi-
tions under which it will be found growing. For most shrubs
a system of ‘‘renewal’’ pruning is all that is necessary. This
consists of removing the older stems, those that are too old
to bloom profusely (plate 10), leaving more room for younger
and more vigorous shoots, which may with some shrubs begin
to flower in two years. This method applies only to shrubs
having the same flowering habit, as the mock-orange (Phila-
delphus), deutzia, nine-bark (Physocarpus), and dogwood
(Cornus). All of these bear flowers on the older wood on
short lateral branches formed the current year. Established
plantings of bridal-wreath (Spiraea) and snow-ball (Vibur-
num) will require little or no pruning. Very old plants may
be much improved by ‘‘renewal’’ pruning (plates 9-11)
if it is extended over two or more years. Hydrangea panicu-
lata and other shrubs which produce flowers on the new growth
will require severe cutting back each year. Choke-cherry
(Aronia), dwarf buckeye (Aesculus), and Kerria produce
flowers on the tips of new wood, and require only the removal
of dead wood. Lilac (Syringa) will not be killed by severe
cutting back, but flowering will be much delayed. Basal shoots
should not be permitted to grow unless the plant is on its own
roots, and ordinarily little pruning is necessary.
Before pruning the flowering habits of the shrubs should
be learned. PauL A. Koxwr,

THE DOGBANE: ROADSIDE WEED AND FUTURE
STAPLE.
Little does the farmer suspect, as he patiently plows
through the patches of hated ‘‘dogbane’’ or ‘‘Indian hemp’’
ever spreading and choking out the grain upon his unproduc-
tive soil, that he is actually engaged in cultivating a plant
which may prove to be a future staple—a plant of many
varied economic uses. If one were to warn him that instead
of exterminating the weed he is actually giving it a still
greater lease on life, he would scarcely believe it. And if he
were told that, properly appreciated, the weed might repay
him much better than the stand of grain which he so indus-
triously tends, he would probably laugh. However, especially
in the western states, the dogbane, or Indian hemp, as it is
sometimes called, is no laughing matter. It is a rank, tough,
ugly weed, which can usually flourish upon much poorer soil
than the commonly cultivated grains. And instead of having
to be resown each year, up it comes without waiting to give
the corn, wheat, or whatever the real crop may be, an even
start. What a boon it would be if the cultivated crop were
so sturdy and trustworthy!
Few of our native plants are more common over a greater
part of the United States than the several species of dogbane,
or Apocynum, the scientific name for the plant. There is
scarcely a roadside or railroad right-of-way which hasn’t
large and frequent patches of it, and almost every farm in
(87)
88 MISSOURI BOTANICAL GARDEN BULLETIN
the country is familiar with it. For in addition to having
seeds which are wonderfully fitted for a wide dispersal, the
plant possesses a system of thick rootstalks specially con-
structed for the production of new plants. Upon these root-
stalks, which do not reach straight down into the earth as
most other roots do, but travel for a long distance just a few
inches beneath the surface, a multitude of tiny buds, or root-
shoots, are produced, each of which eventually develops into
a full-fledged plant. In turn, these plants produce more
rootstalks and more little buds. Each time the farmer’s
plowshare cuts across the under-ground rootstalk, it cuts
off one or many of the little root-shoots, casts them to one
side or even carries them for a distance, where they eventually
settle down to the business of crowding out the crop plants
in the neighborhood. Text-figure 1, diagram 3, illustrates
the under-ground parts of the dogbane. Plate 15 presents
two views of a farm in southern Colorado which has become
almost completely covered with plants of Apocynum medium
var. lividum. This variety has never been known to produce
seed, and must rely entirely upon propagation by cuttings
and root-shoots. Therefore, in all probability, the entire field
has become infested through the division of a single plant.
A great number of other plants also reproduce themselves
by means of root-shoots, notably the Lombardy poplar
and the black locust. This method of propagation is really
more effective than seeds; and some plants have given up the
production of seeds altogether and can only be multiplied
by cuttings or by root-shoots. The Lombardy poplar, which
occurs in such numbers over nearly all the western world, can
only be reproduced in that way. Every Lombardy poplar in the
world is a direct descendant of a single black poplar tree in
northern Italy which devoted its energy to the formation of
a tall spire instead of a bushy tent like its brothers and
sisters. From that single tree, millions of other trees have
been propagated by means of cuttings and root-shoots. At
the present day a sugar-maple tree, of almost the same tall,
slender shape as the Lombardy poplar, is growing in a ceme-
tery in New England. This tree is being carefully watched
by nurserymen; and we may eventually have a ‘‘Lombardy’’
maple.

The seeds of the dogbane much resemble those ot the com-
mon milkweed, having a long comet’s-tail of silky hairs
which a breath of air may blow about after the seed-pod
has burst. Carried into the air they finally land in a place
‘ providing suitable conditions for germination and growth.
The two most common popular names of the Apocynum,
‘‘Indian hemp’’ and ‘‘dogbane,’’ owe their origin to certain
uses which were found for the plant many centuries ago.
The species of Apocynum called Indian hemp contain a tough,
silky fiber which, from the earliest recorded times, was
twisted into crude rope or thread by the Indians of North
America. Conspicuous among the domestic articles found in
the Cliff Dwellings of the southwestern states are rude fabrics
of the fiber from the leaves of the Yucca plant woven with
the silky floss of the Apocynum. The Yucca fiber usually
forms the substantial warp, while that from the Apocynum
constitutes the more delicate woof. Sandals and bowstring
were also made from the strong thread taken from the Apocy-
num stems, and frequently the wooden handles of stone axes
were bound with it.
In the eastern sections of the United States, as well as in
Canada, the aboriginal inhabitants recognized the fiber of
Apoeynum as a valuable article. From them the early
European settlers learned its use. In the sixteenth century
Janus Verrazanus, a Venetian sailor, came upon natives along
the shores of South Carolina wearing clothing made of Span-
ish moss interwoven with cords of Apocynum. From an old
book entitled ‘‘A brief relation of the discovery and planta-
tion of New England . . . from 1607 to this present 1622’’
one is informed that the plant called ‘‘Indian hemp’’ by the
colonists and ‘‘enequen’’ by the Indians is quite a good sub-
stitute for real hemp. Jacques Cartier found natives of the
Bay of St. Lawrence region fishing with nets made from the
same stuff. Still another record of the plant is given by the
old Spanish historian, Alvarado, who related that the famous
explorer, De Soto, after losing his ships on the lower Missis-
sippi, built brigantines from native wood, caulking them with
‘‘the tow of an herb like hemp, called ‘enequen.’ ’’
The name ‘‘dogbane’’ is an instance of a misapplied pop-
ular name which has remained in use in spite of the error.
90 MISSOURI BOTANICAL GARDEN BULLETIN
Like the common mayflower (Podophyllum peltatum), which
many people, botanists included, persist in ealling ‘‘man-
‘drake,’’ the Apocynum does not deserve to be called ‘‘dog-
bane,’’ a name which rightfully belongs to a plant (Cynan-.
chum erectum) found in Greece and around the Adriatie
and Mediterranean Seas generally. The real dogbane of
Europe received its name from the early Greeks, who used
a stew of the stems as a poison for dogs, wolves, rodents,
and other animal pests. Hence the name, which is written
in Greek as &nokuvef, meaning, ‘‘from the dog,’’ or ‘‘bane or
poison for dogs.’’ In some way or other, the North Ameri-
can plant became confused with the European in the minds of
the early botanists. While it is doubtful indeed whether it
was ever used to kill dogs, the early botanists were fully justi-
fied in regarding the American plant as a potential poison.
The poisonous principle of the Apoeynum is contained chiefly
in the milky juice, or latex, which is found in all parts of
the plant. This exudes copiously from a wound, thus re-
sembling the familiar milkweed (Asclepias), as well as the
commonly cultivated rubber plant (Ficus elastica).
But many poisons are also useful as drugs. This fact is
reflected in the word ‘‘pharmacy,’’ derived from the Greek
word Prevost, meaning both a drug and a poison. The root
of Apocynum cannabinum was widely used as a medicinal
herb by the Indians of the southern United States at the time
of the first explorations in that region by the white men.
Especially among the Choctaws and Cherokees was this prac-
tice established. The root was chewed and the juice swal-
lowed as an emetic and diuretic. From the Indians the
medicinal use of Apocynum spread to the woodsmen of Ken-
tucky and Tennessee, and so into the materia medica of the
nation. It is recognized as officinal in the Pharmacopoeia
of the United States, and is recommended in all of the larger
pharmaceutical books. In moderate doses an infusion of the
dried root of Apocynum cannabinum is considered an ex-
cellent diuretic, and is recommended for the treatment of
dropsy and malaria.
In time of war a nation is compelled to examine and take
stock of its natural resources, as at no other period. With
certain important sources of raw materials cut off, substitutes

must be diligently sought. The American people are pro-
verbially resourceful, and during the relatively brief period
of their participation in the war of 1914-18 they discovered
that they were much less dependent upon the outside world
for many commodities than had been suspected. With an
army of technical students and workers enlisted in supply-
ing important raw materials, amazing resources were dis-
covered, especially in the products obtained from the native
flora. Had the United States been forced to rely for a longer
period upon the home production of commodities there
might have developed a number of additional important na-
tional industries; but with the advent of peace many of the
new-found uses for native plants were forgotten or neg-
lected.
One of the most important commodities of civilized life is
rubber, and practically all of the plants from which it
is produced can be grown successfully only in the tropics
and subtropics. During hostilities importation of such im-
portant plant products is frequently impossible, and it is
then that a nation must turn to its neglected natural re-
sources. Immediately after the entrance of the United States
into the war in 1917, the state of California undertook a
survey of the rubber-producing plants of the Great Basin
and Pacifie Coast areas, the work being carried out under
the direction of the State Council of Defense and the Uni-
versity of California. This research examined some 225
latex-producing plants of the western United States, event-
ually centering about several species of Asclepias and Apocy-
num, or, as they are popularly known, the milkweeds and
dogbanes. This was not the first research undertaken to
determine the potentialities of native rubbers. As early as
1875 Asclepias was investigated, and in 1912 Fox! had found
Apocynum androsaemifolium, the so-called ‘‘spreading dog-
bane,’’ to have a rubber content of 2.27 per cent. The later
studies of the State Council of Defense of California, pub-
lished by Hall and Long? in 1921, proved that the genus
Apocynum was not only capable of a much higher percentage

of rubber from the milky juice, or latex, but is really the most
promising of the North American rubber plants. These
authors found A. cannabinum to produce as high as 5.1 per
cent rubber, of a very superior quality.
One of the most significant factors concerned with the
study of the latex of Apocynum is that the rubber-content in-
creases to a large extent with drought and infertility of the
soil. Fox found that plants grown upon dry, sandy soil at
West Akron, Ohio, gave a latex containing 2.27 per cent
rubber, while those growing in the swamps of South Akron
contained only 1.12 per cent rubber. Similarly, Hall and
Long found the highest rubber percentage to be obtained
from certain plants growing in the prairies of central
Nebraska.
While summarizing the conclusions of their experiments,
Hall and Long declare: ‘‘The Indian hemp is considered
as one of the most promising plants for further, investiga-
tions. It is true that most of the analyses indicate only a
small percentage of rubber, but the high yield of No. 1039
[5.1 per cent], together with the ease of vegetative propa-
gation in poor, sandy soils, and the high quality of the
product greatly modifies our opinion of its possibilities.’’
It is interesting to note! that during the recent war the
Germans, being unable to import freely, also resorted to
the manufacture of rubber from certain common weeds,
one of which, Sonchus oleraceus, or common sow-thistle,
grows as an introduced weed in the United States. Appar-
ently the most important weed so used, however, was a sort
of wild lettuce, or Lactuca.
Quite aside from its possible use as a source of rubber of
very satisfactory quality, the dogbanes, as it has already
been related, provide very good fiber. As early as 1897 the
United States Department of Agriculture undertook an inves-
tigation of the fiber-producing plants of the world with the
intent of bettering the nation’s home production of fibers.
During the course of this research, the fiber of Apocynum

MISSOURI BOTANICAL GARDEN BULLETIN 93
cannabinum was spoken of very highly. Dodge!, who pub-
lished the results of the investigation, wrote of this fiber:
“Easily separated from the stalk, and when cleaned is quite
fine, long, and tenacious. In color it is light cinnamon as
usually seen, though finely prepared specimens are creamy
white and remarkably fine and soft; will rank with Asclepias
for strength, and is readily obtained, as the stems are long,
straight, smooth, and slender. Although paper has not been
made of it, it could doubtless be utilized for the purpose. It is
principally employed by the North American Indians, who
manufactured from it in rude fashion bags, mats, small orna-
mental baskets, belts, twine, and other cordage, fishing lines,
and nets. Among fine specimens received is a fish line, such as
is used by the Pai Utes at the Walker River Reservation in
Nevada.”
Later opinions expressed by experts who have examined
Apocynum fiber are that if it could be produced at a cost
that would permit it to compete with hemp or jute, it might
have a commercial value. Although Apocynum has not been
so used, a fair quality of paper has been produced experi-
mentally from Asclepias syriaca, our common milkweed. It
has been stated that machinery could be constructed both to
extract the latex from the plants of Apocynum and to grind
the tissue preparatory to the preparation of paper-pulp.?
As it has been demonstrated that the dogbane attains its
maximum usefulness upon land too arid for agriculture, its
economic possibilities are greatly accentuated. With vast
stretches of such arid and untillable land lying idle in our
western States, and because of the easy propagation of the
plant, the remuneration from such a project should be con-
siderable. At any rate, the wisdom of maintaining a per-
manent national bureau for the discovery and development
of native resources should be apparent.
THE GENUS APOCYNUM IN MISSOURI.
The dogbanes are scarcely among the most attractive of
our native flowers, and many who have read the preceding
account of their economic possibilities probably are unable to

the world. U.S. Dept. Agr. Fiber Investig. Rept. 9. 1897.

94 MISSOURI BOTANICAL GARDEN BULLETIN
recall ever having seen the plants. However, they are rela-
tively common. True, the least attractive of the species are by
far the most frequent. It is a safe supposition that the more
attractive a plant may be the more attention it will attract, far
out of all proportion to its relative frequency as compared
with a less conspicuous although more abundant plant. This
is well demonstrated by our native grasses, which it may be
assumed are the most widespread and common of our plants,
and at the same time the least understood, both by amateur
naturalists and trained botanists.
The dogbane shares with the spiderwort, or Tradescantia,
the fate of the prophet who is not without honor save in his
own country. In Europe, Apocynum androsaemifolium,
known popularly as the ‘‘spreading dogbane,’’ has been cul-
tivated since early days, the exact date of its introduction
being unknown. As early as 1688, however, John Ray men-
tions a plant called ‘‘ Apoecynum flore lilii convallium purpura-
scente’’ as appearing in the famous physic garden at Chelsea,
so we may safely assume that its actual introduction was in
advance of that date. By the last quarter of the eighteenth
century it was evidently widely cultivated on the continent
and viewed as a curiosity because of its propensity for cap-
turing insects.
Although it is now fully understood that insects trapped
within the flowers of Apocynum are probably detained only
by the viscous floral secretions, or ‘‘nectar’’, some fantastic
explanations have been advanced to account for this phenome-
non. The old French biologist, Lamarck, father of one of the
early theories of evolution, was of the impression that me-
chanical pressure exerted by a set of five peg-like nectaries
situated within the flower is responsible for catching the pro-
boscis of the insect. A somewhat more current view was that
the stamens actually grasp the insects just as do the leaves
of the ‘‘Venus’s fly-trap,’’ Dionaea. Erasmus Darwin,! the
grandfather of the author of ‘‘The Voyage of the Beagle’’
and ‘‘The Origin of Species,’’ appears to have been the first
to sponsor this view, and wrote as follows:
“In the Apocynum Androsaemifolium, one kind of Dogsbane,
1 Darwin, E. The botanic garden. Part 2: The loves of the plants.
126. 1791.
MISSOURI BOTANICAL GARDEN BULLETIN 95
the anthers converge over the nectaries, which consist of five
glandular oval corpuscles surrounding the germ; and at the
same time admit air to the nectaries at the interstice between
each anther. But when a fly inserts its proboscis between these
anthers to plunder the honey, they converge closer, and with
such violence as to detain the fly which thus generally
perishes.”
Although it would be wearisome to retell the accounts of
many other authors regarding the insect-catching habit of
Apocynum, the description of the plant by the anonymous
author of ‘‘The Journal of a Naturalist’’! should be included
as perhaps the most fabulous of all:
“But we have one plant in our garden, a native of North
America, than which none can be more cruelly destructive of
animal life, the dogsbane (apocynum androsaemifolium) which
is generally conducive to the death of every fiy that settles upon
it. Allured by the honey on the nectary of the expanded blos-
som, the instant the trunk is protruded to feed on it, the fila-
ments close, and catching the fly by the extremity of its
proboscis, detain the poor prisoner writhing in protracted
struggles until released by death, a death apparently occasioned
by exhaustion alone; the filaments then relax, and the body
falls to the ground. The plant will at times be dusky from the
numbers of imprisoned wretches. This elastic action of the
filaments may be conducive to the fertilization of the seed by
seattering the pollen from the anthers, as in the case of the
berberry; but we are not sensible, that the destruction of the
creatures which excite the action is in any way essential to
the wants or perfection of the plant, and our ignorance favours
the idea of wanton cruelty in the herb; but how little of the
causes and motives of action of created things do we know!”
This highly fictitious narrative is illustrated by a sketch
showing the flower of Apocynum androsaemifolium before:
with outspread stamens awaiting the visit of the victim; and
after: with the anthers pressed tightly about a fly. In justice
to the plant, and deference to the eager public which might
throng to the nearest patch of dogbane to watch the strange
phenomena described above, it must be said that the dog-
bane is not as cruel an herb as the account might lead one
to believe. The number of insects caught is relatively few;
there is not a spectacular elastic movement of the stamens;
and the prisoner may stay until it dries up for all the move-

ment which the plant makes to let ‘‘the body’’ fall to the
sround. The last statement of Erasmus Darwin, however,
or rather the moral to be drawn from it, alone remains
significant.
In order to illustrate the vivid tales of how the dogbane
catches flies, and also to show the reproductive organs of the
plant, a drawing of the floral organs of Apocynum andro-
saemifolium is herewith reproduced. The exterior of the
flower of A. androsaemifolium is typical, in its general struc-
ture, of the genus Apocynum (diagram 2, fig. 1). The appear-
ance as a whole is not unlike that of a large five-lobed bowl
set within a shallow, five-pointed saucer. The bowl is the
corolla of the flower, which represents the fusion of five sep-
arate petals, as we frequently see in such flowers as'the wild
rose, geranium, and the violet. The saucer is the calyx, which
also represents the fusion of five sepals. The corolla is tube- or
bell-shaped, and varies in color from greenish-white to a clear,
pearly white striped with pink. The length varies from about
one-eighth to one-quarter inch, which accounts for the fact
that this plant has not been cultivated for decorative pur-
poses. The green calyx varies from a length equalling that
of the corolla in the small-flowered species, to about one-third
the length of the corolla of the large-flowered forms.
Diagram 1 of text-fig. 1 illustrates the condition of the
organs within the flower. ) 4 a

ROCK GARDENS FOR ST. LOUIS AND VICINITY
Of all the types of gardens in which one may specialize,
the true rock garden has usually been considered so poorly
adapted to St. Louis conditions that it was useless to attempt
even a smnall one, While it is a fact that many of the alpine
plants which constitute such an important part of the rock
vardens of Europe and of the eastern United States cannot
be grown successfully here, there are fortunately many other
plants which can be used. Naturally, a form of gardening
which has been called ‘‘the most intriguing of all’’ should
not be neglected because it is difficult; and at least a few
earden lovers in and about St. Louis have demonstrated what
can be done with this type of planting.
That there is a growing interest in rock gardens throughout
the United States is manifest. Books and magazine articles
diseuss at leneth the subject from every standpoint, and there
is now available a wealth of literature from which one may
learn the essential facts necessary at least to plant such a
garden. But a word of caution may not be out of place. If
the plants used so successfully in cooler climates are dupli-
‘cated in rock gardens in this vicinity, the results are almost
certain to be disappointing. Ileaping up stones may produce
a rock pile or even a “‘rockery’’, but unless the plants used
will establish themselves and survive during the season, by
no stretch of the imagination can it be called a garden.
Without attempting to describe the various types of rock

vardens, such as ‘‘natural,’’ ‘‘artificial,’’ ‘‘wall,’’ and to dis-
tinguish between them and a so-called ‘‘wild garden,’’ it has
seemed advisable to give actual results obtained in this part
of the country. Consequently there have been selected some
of the suecessful gardens around St. Louis which most nearly
approach the rock-garden class. Different types have been
chosen illustrating the possibilities of various settings and
localities, and it is believed these practical examples will be
more beneficial to one contemplating a rock garden than any
veneral discussion on the subject. There is also appended a
list of a few of the more recent books on rock gardens which
may be consulted at the Garden library.

an interesting walled formal garden, which must have been
beautiful in tulip time, one steps on to an open lawn shaded
by large oaks. At a distance is seen a mass plantation of
pines, spruces, arborvitae, cedars, and deciduous trees and
shrubs, behind which a delightfully arranged rock garden is
hidden. This garden is 100 x 150 feet and slopes toward the
west. Small hills and rock glades with interwinding walks
compose the entire area except the western portion, where a
small waterfall with a rustie bridge is featured. In the early
spring color effect is produced by bulb plants, such as snow-
drops, museari, crocus, scillas, tulips, Jris pumila, followed by
aubrietias, phlox, arabis, primroses, anchusas, Polemonium

PF. C. Thompson, Big Bend Road, Webster Groves (pls.
18-19).—For the last twenty years Mr. Thompson has devoted
his efforts to bringing together the largest possible collection
of shade-loving rock plants, the greater number being either
local or North American species. The rock garden is situated
in the southwestern part of his estate. Its contour is a gradual
slope of twenty feet from north to southwest, and a northern
exposure is created by massive trees which shelter it on the
south. The garden is an irregular glade formation, with inter-
winding walks of stepping-stones and ledges. Through the
middle eleven pools are connected by a series of cascades
which finally terminate in an irregular pond, 150 feet long,
planted with domestic water-lilies. An electric water pump
forces the water up hill from the lake to the upper cascade,
whence it again falls down the series of cascades into the lake.
The first impression of the garden is that of a beautiful
fern glen. Some of the earliest-blooming flowers are the
native blue-bell (Mertensia virginica) and Phlox divaricata,
planted or naturalized between the native ferns, blood-root,
violets in variety, spring-beauty (Claytonia virginica), tril-
liums, dicentras, ete. Mr. Thompson called attention to a
rock ledge shaded by tall trees, entirely covered with the
tender greenhouse Saxifraga sarmentosa and mats of glossy
green leaves of Pachysandra terminalis, both planted fifteen
years ago. A few steps toward the east, in a similar loea-
tion and position, some interesting ericaceous plants were
pointed out with pride: Gaultheria procumbens (partridge
berry), which has been established for over five years and
which flowered for the first time last year; Epigaea repens
(trailing arbutus), planted summer before last and repre-

THE EARLY DAYS OF ‘MR. SHAW’S GARDEN”
Because of the developments which have taken place since
the death of Henry Shaw, one is apt to lose sight of the
unique position held by his garden during the lifetime of its:
founder. An old number of ‘‘The Gardener’s Monthly and
Horticultural Advertiser’’, edited by Thomas Meehan and
published in Philadelphia, was recently presented to the
Garden library by Dr. William C. Wilson, of St. Charles, Mo.
This number, which appeared in August, 1868, contains an
interesting account of the Garden as it was sixty years ago.
Because of the light it throws upon the outstanding position
of ‘‘Mr. Shaw’s Garden’’ at that time, as well as certain infor-
mation relative to the content of the Garden in its early days,
it is printed herewith in full:
THE BOTANIC GARDEN, ST. LOUIS, MO.
Mr. Henry Shaw is one of those liberal public spirited men who
do so much honor to the United States. Some take pride in endow-
ing and establishing one kind of institution, some others. Mr.
Shaw’s taste leads him to botany, arboriculture, and gardening.
His Botanic Garden and residence at Tower Grove is unequalled by
anything of the kind in the United States, and indeed by few others
in the world. A substantial and handsome stone wall, with an
imposing arched entrance, encloses the garden proper. This en-
closed area is divided into suitable compartments, for the systematic
arrangement of herbaceous and other plants of low growth. An
architectural flower garden, sunk somewhat below the general level,
(119)

and surrounded by a grass terrace formed an attractive point. There
is also within this main enclosure a portion of ground which has
been set apart for a Fruticetum, or general collection of all hardy
fruit-bearing trees; this will be of much interest, and has already
been enriched by a considerable number of plants.
An Arboretum is also commenced, a field of thirty acres having
been appropriated for the purpose, and a finer opportunity for dis-
playing the relative beauties and peculiarities of trees could not be
desired. The soil is rich prairie-loam, well adapted to tree growth,
and the ground is sufficiently elevated and undulating to insure
drainage; an injurious retention of moisture during winter months
being the greatest attending evils of these rich soils.
The hot-house department is quite extensive, and the various
collections are gradually being filled up. A new palm or tropical
house on a magnificent scale was being constructed. The acacia
and cactus families are so far the most extensive, although, of
course, very far from being complete; there are also quite a number
of palms and numerous miscellaneous plants, all in robust health,
clean and kept in the finest condition. One of the hot-houses is
built with a ridge and furrow roof, a style seldom adopted now on
a single slope or lean-to house, although its only objection is prob-
ably that of cost; houses so built are as suitable for plant structures
as any other.
A noticeable improvement is a large building of elegant propor-
tions, which is to be devoted to the purpose of a Museum of Botany.
‘The interior fittings are being finished in an elaborate manner, The
eeiling of the principal room is enriched by emblematic frescoes,
and the names of Linneus, Jussieu, Endlicher, De Candolle, Brown,
Hooker, Lindley, Gray and Engelmann, are placed in conspicuous
niches. The Herbarium already embraces forty thousand speci-
mens, and is constantly receiving additions.
The whole of this beautiful place is thrown open freely to the
public every day in the week, and the greatest pleasure of the
liberal proprietor is to see how freely the public enjoy themselves,
and to reflect on the immense power which such refined influences
have on the general happiness of mankind. It is difficult indeed to
form an estimate of the full value of such liberality. Thousands
here have created in them the first germs of usefulness which
operate in so many ways. In Botany already the whole world
looks to St. Louis. The name of Engelmann is honored wherever
Botany thrives; and we believe we violate no confidence in saying,
that the name of Shaw, Engelmann, and the Botanic garden will go
down into history together. A rather sad but yet interesting fea-
ture of the ground was the lots set apart for the future resting
place of Mr. Shaw and Dr. Engelmann. It was sad to reflect that
the noblest minds amongst humanity, whose whole lives are devoted
to the happiness of their fellow men, and the development of science
to which we all owe half the comforts and pleasures of the present
age, received no more consideration from the hands of death than

MINIATURE GLASS GARDENS FOR THE HOME
Although the Wardian case as a means of shipping plants
successfully between widely separated countries has long been
well known to both botanical and commercial institutions,
it is only within comparatively recent years that miniature
Wardian cases, or glass-enclosed gardens, for the home have
become popular, or have seemed even feasible. The Novem-
ber, 1914, number of the BULLETIN contained an extensive
article on the history, use, and construction of Wardian
cases, and therefore only a short resumé will be given here.
Nearly a hundred years ago, Nathaniel Ward, a London
physician, stumbled upon a method of raising and keeping
plants in an environment supposedly quite unsuited to them.
He had built for himself in his London garden a brick-
walled corner and had carefully planted it with the mosses
and ferns which he so earnestly desired to grow. Much to
his distress the fog and smoke of London killed all his plants
one by one. One day he discovered the cocoon of a sphinx
moth, placed it in a large-mouthed glass bottle containing
some rich damp loam, and covered it with a lid. Much to
his surprise, within a few weeks a young fern and small grass
plant made their appearance and continued to grow in the
covered bottle. For nearly four years he kept these plants
in the bottle and would have probably kept them indefinitely
had the bottle not been accidentally destroyed.
Dr. Ward then began to experiment with many plants in
(131)
132 MISSOURI BOTANICAL GARDEN BULLETIN
cases of various sizes and shapes until finally his invention
found a very practical use in transporting plants between
foreign countries. In those days of sailing vessels, when a
voyage might last for eight months, especially when it in-
volved crossing the equator, the transportation of plants was
a difficult problem. They would die from cold, from heat,
from lack of water, from gases in the hold of the ship, ete.
In 1833 two cases were filled with plants and sent from
England to Sidney, Australia, where they were emptied, re-
filled with other plants and sent back. The cases were kept
on deck and the plants not once watered during the eight-
months voyage, yet they arrived in perfectly healthy and
vigorous condition. A letter from Captain Mallard, in
charge of this ship, to Dr. Ward, concludes: ‘‘Allow me to
offer you my warm congratulations upon the success of this
simple but beautiful discovery for the preservation of plants
in. the living state upon the longest voyage; and I feel not a
little pride in having been the instrument by which the truth
of your new principle has been fully proved by experiment.”’
Elaborate instructions as to the making of small Wardian
eases for the home have appeared in various publications
during the past few years, but to the ordinary householder
without the gift of carpentry, building the necessary wooden
framework and fitting it with glass seems too great a task.
Looking about for some easier method of bringing a bit of
the summer woods indoors for the winter, Miss Ruth Barry,
one of the most successful amateur gardeners in St. Louis,
had the happy inspiration of building these small gardens
in glass globes, thus eliminating the labor of construction,
as well as reducing the expense so as to bring the gardens
within reach of almost any one. After considerable experi-
mentation the type of globe decided upon as producing the
best results was a two-gallon clear-glass aquarium with two
flat sides and a round hole at the top. Smaller sizes of the
same type can of course be used, but then the difficulty of
keeping the scale of the plants and finished garden down to
that of a smaller bowl is hard to overcome. These bowls may
be purchased at any department store or shop where goldfish
are for sale. It should be borne in mind that the glass must

be clear, since the plants will not flourish in bowls of tinted
glass.
After cleaning and polishing the bowl, place a large hand-
ful of charcoal chunks in the bottom, to aid in keeping the
soil ‘‘sweet.’’ A handful of broken flower pots is then added
and finally the soil. The mixture of soil usually advocated
is one-third each of ordinary garden soil, leaf mold, and
sand, and these proportions can very well be followed by
those who do not have access to natural leaf mold from the
woods. It has been found, however, that if the plants come
from the woods (and these are on the whole the most suc-
cessful) well-rotted leaf mold collected in the woods at the
same time as the plants, combined with one-third sand,
makes an ideal soil for the gardens. The soil should be sat-
urated with water, that is, it should be so wet that when
taken in the hands and placed in the bowl the water almost
drips from it. Fill the bowl about one-third full of this soil,
arranging it unevenly so as to give the effect of a natural
woodland, with tiny hills and valleys. While putting in the
soil quantities of green moss should be forced down the flat
sides of the bowl, together with a few colored stones and
shells, so that the sides will be attractive. This moss will
continue to grow upward through the soil and give the
appearance of a miniature forest.
Naturally the most important matter now is what plants
to use and where to obtain them. Experience has taught
that the best source of supply is our own native woods. It
is not necessary to go far from the city to find a wealth of
material admirably well suited for the purpose. A brook-
side leading from a spring which has not gone dry during
the summer is a good collecting place. Gather quantities of
soft green moss, all the varieties that can be found growing
on soil, not on wood, the tiniest ferns that ean be found, the
smallest imaginable seedlings of spruce, pine, and cedar, none
over three inches in height. Until you have made one of
these gardens it is almost impossible to realize how very
small the plants must be to conform to the scale of the fin-
ished garden. In case it is impossible to gather material
in the woods, a successful garden may be made from such
134 MISSOURI BOTANICAL GARDEN BULLETIN
plants as very small palm seedlings, snake grass, myrtella,
selaginella, croton, green and white variegated pandanus, ete.
Sprigs of box or barberry stuck in the soil will root and grow
most effectively. In general, avoid plants with succulent
leaves and stems, with the one exception of the common
begonia. Rooted cuttings of begonia, which begin to bloom
almost at once, add a pleasing touch of color to the small
garden and if carefully watched will last a long time. Half
the fun of these gardens, however, is the trip to the woods
for material. As late as the middle of November, in small
gulleys under fallen leaves, may be found quantities of baby
ferns and fat hummocks of bright green moss to use in mak-
ing the gardens for Christmas gifts.
After all the larger plants are arranged according to indi-
vidual fancy and planted, the surface of the ground should
be covered with as many varieties of moss as ean be found
and very small-leaved ground-cover plants. A few small
boulder-shaped rocks, a shell or two, tiny Buddhas or dwarf
figures may be used beneath the trees. Very small round
mirrors, shellacked on the back to prevent penetration of
moisture, make quite natural-appearing lakes. Ambitious
makers of these gardens follow a definite landscape plan,
with paths and pergolas and even miniature rock gardens.
When the garden is planted, carefully clean from the glass
all smears of soil, place a flat glass plate on top as a lid and
establish the bowl in a north window. It should never be
placed in direct sunlight, since the intense heat created in-
side the closed bowl will injure the plants in an almost un-
believably short time. Keep the glass lid on the bowl almost
constantly. The moisture observed on the inside of bowl and
lid each morning will fall on the plants and be absorbed
later in the day. Look at the garden each day, and if at
any time mold is observed on the soil or plants, tip the lid
to one side a trifle and leave it so for a half-day. Test the
soil once in a while with the finger to see if it is moist,
and if not, sprinkle very lightly with a fine spray of water.
This should very seldom be necessary, however, since the
moisture which naturally forms inside the bowl is sufficient
for the plants. These gardens may be kept for many years

practically with the same contents as when started, though
occasional replacements with smaller plants or fresh moss
are sometimes desirable. Keeping the air free from soot, the

FASHIONS IN FLOWERS
That there are fashions in flowers and landscape effects, as
well as in architecture and in clothes, is easily proved by a
glance into the back numbers of almost any magazine dealing
with floriculture and so-called artistic planting. Just as large
hats atop enormous pompadours, mutton-leg sleeves, and
waspish waist lines are now objects of mirth, so do the pic-
tures of elaborate plantations in the parks and gardens of
forty years ago rouse ridicule at the peculiar taste that could
have fancied such monstrosities, and just so perhaps will the
knee-length dresses, bobbed hair, and rock gardens of this
age affect the more erudite generation which is to follow us.
One of the most striking examples of the so-called ‘‘carpet
bedding”’ of the eighties was that established in Washington
Park, Chicago, in the summer of 1888. Mr. James M. Gurney,
Jr., Superintendent of Tower Grove Park, found the
old photograph (here reproduced), and it is to him that the
BULLETIN is indebted for the information which forms the
basis of this article. Mr. Kanst, of Chicago, now 83 years
old, father-in-law of Mr. Gurney, was the author of this
especially interesting bit of work, and without either defend-
ing or condemning the fashion of that day, he simply insists
that ‘‘beauty is in the eye of the beholder’’ and lets the
matter rest with that. Below is Mr. Gurney’s explanation
of the photograph:
‘The planting pictured includes two row-boats, rowed from
opposite directions toward the same goal, a large chair on
the back of which grows the date ‘1888.’ Seated in each
boat is a man, literally implanted at the oars, and endowed
with individual facial characteristics (likenesses were
achieved by infinite detail work in the selection and shading
136 MISSOURI BOTANICAL GARDEN BULLETIN
of plants used). Directly in back of the chair looms a floral
post, on top of which sits an owl, presumably of the wise
variety, and directly under the owl his immortal utterance,
‘HOO,’ asks it with plants.
“Now for the explanation: Cleveland and Harrison were
the Democratic and Republican candidates for the Presi-
dential chair that year, 1888, and Mr. Kanst indulged his
notion of mixing politics with a bit of floral cartooning.
“At that time visitors to Chicago parks were greatly
pleased with the apparent popularity of the floral fancies
of carpet bedding. Whether it was worth doing (and no
one can deny it was laborious work requiring skill when
well executed) did not enter into the doing for this again
was the fashion of the day, and thousands of succulents and
dwarf plants were offered up or coaxed to embroider lawn
areas in the prevailing style.’’ HK 28. 1,
THE NATIONAL ORCHID SHOW
The fourth national exhibition of orchids given by the
American Orchid Society was held in the ball-room of the
Willard Hotel, Washington, D. C., October 16-18. The num-
ber of exhibitors, both private and commercial, exceeded that
of past orchid shows, and the type of flowers showed that
the orchid hybridist and enthusiast is striving for a higher
standard in quality. Due to the show being held in October,
instead of May as heretofore, the plants represented different
genera from those formerly displayed at orchid shows. The
greatest number of specimens were Cattleya species and
hybrids, the number of Odontoglossums was limited, and
there was an absence of Cymbidiums, Dendrobiums, Mil-
tonias, and Phalaenopsis. A few rare plants of Vanda were
seen, one specimen, Vanda Lowii, bearing three pendent
spikes, four feet in length, with both staminate and pistillate
flowers. The largest single-specimen orchid was Cattleya
Bowringiana, bearing more than two hundred flowers of a
deep mauve color. Despite the season, Paphiopedilum (Cypri-
pedium) was well represented and showed the great strides
made by hybridization in this genus, especially in increasing
the size of the dorsal sepal. The Odontoglossum group was
PLATE 31.

MISSOURI BOTANICAL GARDEN BULLETIN 137
awarded the first prize for the most artistic exhibit in the
show, and Cattleya x ‘‘Mona’’ was given a prize for the best
hybrid seedling of American origin not previously exhibited.
Missourt Botanical Garden Exhibit—The Garden sent an
exhibit illustrating the development of orchids from seed to
the mature plant. One hundred Erlenmeyer flasks contained
the seedlings in various stages of growth from two weeks to
eight months old. A complete succession from this stage to
the flowering plant was demonstrated by numerous potted
plants from those in thimble-size pots to six-inch size. The
symbiotic and asymbiotic methods of germination could be
compared by examples of plants one and four months old.
The various genera represented were: Cattleya, Laeliocatt-
leya, Brassolaeliocattleya, Rolfeara, Potinera, Cymbidium,
Dendrobium, Zygopetalum, Odontoglossum, Oncidium, Vanda,
and Phalaenopsis. Seed-pods in various stages of develop-
ment were displayed, and a quantity of the minute seed from
the ripe pod was shown in a Petri dish.
Demonstrations of the actual work of removing the seed-
ling from flask to flask and from flask to the thimble pots
were given three times daily. The attendance at these demon-
strations and the daily broadcasting over the radio of the talk
connected with them attested to the interest and enthusiasm
in the Garden exhibit. A special demonstration was given
Mrs. Herbert Hoover and distinguished visitors during the
private viewing of the show which was held on Thursday
afternoon, October 18, following the completion of the
judging.
The Garden received the Mrs. F. E. Dixon silver cup as
a first prize for the exhibit showing the development of
orchids from seed. The large exhibition gold medal of the
American Orchid Society was awarded to Elinor Alberts
Linder, Orchidologist to the Garden, for horticultural effort
in developing the growing of orchids from seed.

SOME FACTS ABOUT THE GARDEN
The Missouri Botanical Garden was opened to the public by Mr.
Henry Shaw about 1860. From that date to the death of Mr. Shaw,
in 1889, the Garden was maintained under the personal direction
of its founder, and, while virtually a private garden, it was,
except at certain stated times, always open to the public. Although
popularly known as “Shaw’s Garden” the name Missouri
Botanical Garden was designated by Mr. Shaw as its official title
and in his will or in any of his writings he specifically referred
to it as the “Missouri Botanical Garden.” By a provision of
Mr. Shaw’s will the Garden passed at his death into the hands
of a Board of Trustees. The original members of the Board were
designated in the will, and the board so constituted, exclusive of
certain ex-officio members, is self-perpetuating. By a further pro-
vision of the will, the immediate direction of the Garden is vested
in a Director, appointed by the Board of Trustees. The Garden
receives no income from city or state, but is supported entirely
from funds left by the founder.
The city Garden comprises 75 acres, where about 12,000 species
of plants are growing. There is now in process of development a
tract of land of over 1,500 acres outside the city limits which is to
be devoted to (1) the propagation and growing of plants, trees and
shrubs, designed for showing either indoors or outside, at the city
Garden, thus avoiding the existing difficulties of growing plants in
the city atmosphere; (2) gradually establishing an arboretum as
well as holding a certain area as a forest reservation, with the idea
that possibly at some future time this may become the new botani-
cal garden.
The Garden is open to the public every day in the year, except
New Year’s Day and Christmas—week days from 8:00 a. m. until
one-half hour after sunset; Sundays from 10 a. m. until sunset.
The main entrance to the Garden is located at Tower Grove ave-
nue and Flora place, on the Sarah car line (No. 42). Transfer
south from all intersecting lines. The Garden may also be reached
by Bus Route No. 12, to which all other motorbus lines transfer.

THE THREE HUNDREDTH ANNIVERSARY
OF THE
FIRST RECOGNIZED USE OF CINCHONA
HELD AT THE MISSOURI BOTANICAL GARDEN, OCTOBER 31
AND NOVEMBER 1, 1930.
For three hundred years mankind has enjoyed the blessing
of the febrifuge properties of cinchona or quinine bark. Noth-
ing is actually known as to the discovery of the febrifuge
properties of this bark, but many legends concerning it are
to be found in historical archives. One of the most interest-
ing is that some trees in the Peruvian wilds were blown into
a pool by the wind, and thereby the water became very bitter,
in fact so bitter that the natives refused to drink it. One day
a native was seized with a violent fever, and finding no other
water to quench his thirst, he was foreed to drink of the
water from this pool, with the result that he was cured. He
then related his wonderful discovery to the other inhabitants
of the district, and thus the fame of the febrifuge qualities of
einchona bark became known.
The year 1638 has been generally accepted as the date of
the first recognized use of this bark, in which year Countess
Ana de Chinchon, wife of the viceroy of Peru, Luis Geronimo
Fernandez de Cabrera y Bobadilla, was cured of the intermit-
tent fever. The powdered bark used in this connection had
been received from a Spanish corregidor, Don Juan Lopez de
Canizares, who having learned of the illness of the Countess,
(141)
142 MISSOURI BOTANICAL GARDEN BULLETIN
had sent a packet of the powdered drug to Don Juan de Vega,
her physician.
Search among the old books at the Missouri Botanical Gar-
den library revealed the fact that eight years earlier this
Spanish corregidor had likewise been cured of the intermittent
fever by means of cinchona bark, thus establishing the date of
the first recognized use of cinchona as the year 1630. It is
interesting to note that this finding has been verified by
Dr. E. M. Holmes, Ph. C., president of the British Pharma-
ceutical Conference, in an article entitled, ‘‘Three Hundred
Years of Cinchona’’ which recently appeared in the ‘‘ Chemist
and Druggist’’ (London).
Upon recovery, the Countess Ana de Chinchon caused the
bark to be collected in large quantities and given to others
who were suffering from intermittent fever. The powdered
bark then became known as Polvo de la Condesa, i. e., the
Countess’ Powder. In the spring of 1640, the Countess re-
turned to her native home, Chinchon, in Spain, bringing with
her a quantity of the remedy for distribution to the sufferers
of the tertian ague on her husband’s estate. Dr. Juan de
Vega, physician to the Countess, followed his patient back
to Spain and he also brought with him a quantity of cin-
chona bark, which he sold at Seville for 100 reals (one real is
equivalent to 10 cents) per pound. Some authorities state
that cinchona bark had found its way to Spain in 1639, one
year before the return of the Countess, for in that year it had
been tried at Aleala de Henares, near Madrid.
Owing to the many requests for the Countess’ Powder, the
Countess of Chinchon transferred the distribution of this bark
to the Jesuit fathers, it then being assigned the name of
Jesuit’s bark.
In 1649, a large quantity of the bark was exported to
Europe by the Jesuit fathers, being received by Cardinal
Juan de Lugo at Rome, who distributed it to members of that
fraternity throughout Europe. It was later carried to Bel-
gium by these same priests. Jesuit’s bark was introduced
into England by James Tompson, a merchant of Antwerp,
and in 1655, when there was a wide-spread epidemie of inter-
mittent fever, it became greatly advertised.
Robert Talbor, an apprentice to Dean, an apothecary of
Cambridge, took an active part in the usage of Jesuit’s
MISSOURI BOTANICAL GARDEN BULLETIN 143
powder. In 1672 he published a book dealing with the cause
and cure of agues. Through his cures his reputation rapidly
spread, and in 1678 he was appointed physician to King
Charles II. In 1679 he visted France and cured a number of
prominent persons of intermittent fever, but he was always
very careful not to let it be known that he was employing
Jesuit’s bark in the treatment. Louis XIV, having been in-
formed of Talbor’s remarkable achievements with intermit-
tent fever, induced him to sell his secret for the sum of 2000
livres (a livre at that time being equivalent to about twenty
cents). Talbor died in 1681, in which year Louis XIV pub-
lished his method of curing intermittent fever.
Although the bark was employed in 1630 in effecting a cure
for Don Juan Lopez de Canizares, and afterwards was widely
diffused and utilized throughout Europe, no attention was
devoted to the sources of this remarkable bark for almost one
hundred years. The first authentic record of anyone seeking
the source of cinchona is that of the endeavor of Charles-
Marie de la Condamine, a French astronomer, who, when meas-
uring the are of a degree near Quito, availed himself of the
opportunity of being in the vicinity to investigate the origin of
the famous Peruvian bark. In the year 1737 (February), he
collected specimens of this bark at Sierra de Cajanuma, about
two and one-half leagues from Loxa, where the Spanish cor-
regidor, Don Juan de Canizares, had been cured of the inter-
mittent fever in 1630. In 1738 he published an account of
his findings, which was supplemented with a number of illus-
trations.
In 1742, Linnaeus, the father of the binomial system of
plant nomenclature, assigned the name of Cinchona to this
genus of plants in honor of the Countess of Chinchon. In
so doing he was not aware that he had left out the letter ‘‘h’’
in the spelling of the word ‘‘Chinchon,’’ with the result that
this genus of plants then became known as ‘‘Cinchona”’ in-
stead of ‘‘Chinchona.’’ His mistake was not discovered until
many years later. Several attempts have been made to cor-
rect the error, one such an attempt being made at an inter-
national botanical congress, but without avail. The name
‘*Cinchona’’ had become too firmly implanted in the minds
of the botanists and quinologists, and the Linnaean spelling
144 MISSOURI BOTANICAL GARDEN BULLETIN
was Tecognized by the Revision Committee of the United
States Pharmacopoeia (Tenth Decennial Revision).
Following the work of Condamine, many expeditions set
forth to South America. These expeditions were in charge
of such men as Markham, Mutis, Ruiz and Pavon, Caldas,
Humboldt, Bonpland, Weddell, Tafalla, and others.
Much difficulty was encountered in removing the cinchona
from South America, especially the seeds. The inhabitants
of the cinchona areas in South America became suspicious
of the real intent of the plant collectors and made every
effort to prevent them from shipping the seed to Europe.
Beyond a doubt, no other group of drug plant explorers suf-
fered more hardships than those who went forth in search of
the famous cinchona trees. An excellent account of the many
trials encountered by Markham has been given in a book,

into the winter with too little water in the soil. A dry wind
in early spring, with the ground dry or frozen, causes the tips
of the branches to brown, not from disease or freezing but
from drouth. The conifers at the Garden Extension at Gray
Summit are well watered during the fall and the ground
around each plant covered with a straw mulch. About 2000
young trees were transplanted to the new Pinetum in 1929,
and despite their exposure to full sunshine, the loss so far
has been negligible. On the other hand, during the fall of
1928 several hundred cedars which were dug from the glades
near the Meramec River and planted alone the Manchester
Road where the necessary water could not be supplied showed
a loss of sixty per cent.
Some of the deciduous shrubs show a greater mortality if
planted in the late fall than in the spring. Fall-planted
shrubs in many cases show a heavy freeze-back in the spring,
especially if there has been a dry winter. If planted in the
early fall and kept watered. there is time enough before the
approach of extreme winter to repair the injury to the roots
caused by digging and moving. If vacant spaces are left
around the roots, due to imperfect firming of soil, the exposed
roots dry up, reducing still further the chances of success.
The roots are not nearly as apt to be harmed during the
winter by freezing if there is close contact with the soil.
Many experienced nurserymen in this vicinity prefer spring
planting for those varieties of trees and shrubs most subject
to winter killing, since extra attention and protection may
thus be avoided. The following plants may be regarded as
falling within this group: magnolia, lilac, Cornus florida,
red-bud, willow, Lombardy poplar, birch, beech, tulip, and
sweet-gum. The two last mentioned are regarded as the most
difficult to move, either in spring or fall. For this reason the
nurserymen offer these trees shipped B. B. (balled and bur-
laped), the same as evergreens.
It is not intended in this article to diseredit fall planting.
On the contrary, many plants will succeed if moved at this
time of the year, and conditions may necessitate the trans-
planting of even those mentioned above in the fall rather than
the spring. Extra precautions should be taken, however, to
see that the trees and shrubs moved are not left to the mercy
OO ee ee te ew soe

of the elements before they have become established. The
nurseryman should not be accused of disposing of inferior
stock when the loss is due to neglect or an unwillingness to
meet the extra cost of additional watering and winter pro-
tection. Ae Ee B.

SOME FACTS ABOUT THE GARDEN
The Missouri Botanical Garden was opened to the public by Mr.
Henry Shaw about 1860. From that date to the death of Mr. Shaw,
in 1889, the Garden was maintained under the personal direction
of its founder, and, while virtually a private garden, it was,
except at certain stated times, always open to the public. Although
popularly known as “Shaw’s Garden” the name Missouri
Botanical Garden was designated by Mr. Shaw as its official title
and in his will or in any of his writings he specifically referred
to it as the “Missouri Botanical Garden.” By a provision of
Mr. Shaw’s will the Garden passed at his death into the hands
of a Board of Trustees. The original members of the Board were
designated in the will, and the board so constituted, exclusive of
certain ex-officio members, is self-perpetuating. By a further pro
vision of the will, the immediate direction of the Garden is vested
in a Director, appointed by the Board of Trustees. The Garden
receives no income from city or state, but is supported entirely
from funds left by the founder.
The city Garden comprises 75 acres, where about 12,000 species
of plants are growing. There is now in process of development a
tract of land of over 1,500 acres outside the city limits which is to
be devoted to (1) the propagation and growing of plants, trees and
shrubs, designed for showing either indoors or outside, at the city
Garden, thus avoiding the existing difficulties of growing plants in
the city atmosphere; (2) gradually establishing an arboretum as
well as holding a certain area as a forest reservation, with the idea
that possibly at some future time this may become the new botani-
cal garden.
The Garden is open to the public every day in the year, except
New Year’s Day and Christmas—week days from 8:00 a. m. until
one-half hour after sunset; Sundays from 10 a. m. until sunset.
The main entrance to the Garden is located at Tower Grove ave-
nue and Flora place, on the Sarah car line (No. 42). Transfer
south from all intersecting lines. The Garden may also be reached
by Bus Route No. 12, to which all other motorbus lines transfer.
