PREFACE. 



The first volume of this work having been at length comple- 
ted, the authors have to perform the pleasing duty of offering 
their acknowledgments to their numerous friends and corres- 
pondents who have rendered important assistance to their 
arduous undertaking. 

To Sir William Hooker, than whom perhaps no person has 

^ done more for the advancement of North American Botany, we 

~ are largely indebted, not only for the opportunity of consulting 

'^^ his rich herbarium and excellent library under the most 

■a"i favorable circumstances, on two different occasions, but for the 

generous communication of a great number of authentic speci- 

^ mens of the plants described in the Flora Boreali- Americana, the 

Botany of Capt. Beechey^s Voyage, and other works, selected 

^ from the collections made in the Northern land expeditions of 

''' Capt. Sir John Franklin, those of the Arctic voyages of discovery, 

Lij and especially from those made in Oregon, the Rocky Mountains, 

&c. by the late Mr. Drummond, the late indefatigable Douglas, 

^ Mr. Tolmie, and others. To Dr. Richardson we are directly 

J indebted for many plants collected by himself in Capt. Frankhn's

X PREFACE. 

a portion of the plants collected during his travels in Arkansas 
in the year 1819. 

Our acknowledgments are also due to the Botanical Com- 
mittee of the Academy of Natural Sciences, Philadelphia, 
who have obligingly afforded us every facility in consulting the 
large herbarium of that Society, which includes that of the late 
Mr. Von Schw^einitz, and the chief collections of Mr. Nuttall. 
To the urbanity of Mr. Vaughan, the Librarian of the Ameri- 
can Philosophical Society, we are indebted for the opportunity 
of examining the botanical collections in the custody of that 
Society, comprising the herbarium of Muhlenberg, and that of 
the late Professor Benjamin Smith Barton, which appears to 
have been formed by Pursh, and contains many of his plants. 

To the daughter of the lamented Elliott, we desire to 
express our thanks for kindly entrusting to our charge a portion 
of her late father's herbarium ; and also to Prof. Bachman and 
Prof. GiBBEs of Charleston, South Carolina, who kindly select- 
ed and transmitted to us the specimens which we desired. 

To Mr. B. D. Greene of Boston, for the loan of a very 
complete set of the plants collected by the late Mr. Drummond 
in Texas. 

To our numerous correspondents in different parts of the 
country, who have from time to time furnished us with valuable 
collections and observations, our limits will only allow us to 
offer our acknowledgments in general terms. Their names 
frequently occur throughout the pages of this work, where we 
have endeavored faithfully to indicate the sources from which 
our specimens have been derived, as fully as the plan of the 
work would permit. But whenever a species has been received 
from several correspondents, and from different sections of the 
country, we are obliged, in most cases, to omit the citation of 
particular locaUties, and to give as nearly as possible its geo- 
graphical range. Additional specimens of many rare plants 
described in this volume have also been received since the 
Orders to which they belong were printed ; and we have only 
space to notice the more important of these accessions in the 
Supplement, this volume having already extended much beyond 



PREFACK. XI 

its intended limits. Wc would therefore, at present, briefly 
state, that wc arc indebted to the following persons,, to many of 
them very largely, for the plants of particular districts, accom- 
panied in many instances by valuable notes and observations, 
viz : 

To Prof. BiGELow, Mr. B. D. Greene, and Mr. Edward 
TucKERMAN, Jr. of Bostou, Mr. Oakes of Ipswich, Dr. Jacob 
Porter of Plainficld, and Mr. T. A. Green of New-Bedford, 
Massachusetts, Prof. Hitchcock of Amherst College, as well as 
to Prof. Emmons, late of Williams College, and Prof. Dewey, late 
of Pittsfield, Massachusetts, for plants from various portions of 
that state as well as of Maine and New-Hampshire. 

To Dr. Barratt of Middletown, Connecticut, for the plants 
of that neighborhood, and also from the White Mountains of 
New Hampshire, &c. : also to Prof. Tully, of Yale College, 
for some interesting plants. 

For plants of the State of New York, to Dr. Stevenson of 
Cambridge, Washington County, Dr. Bradley of Monroe Coun- 
ty, Dr. H. P. Sartwell of Penn Yan, Yates County, Mr. David 
Thomas of Cayuga County, Dr. Crawe of Jefferson County, Dr. 
AiKiN formerly of Troy, Prof. Lewis C. Beck formerly of Al- 
bany, Mr. A. J. Downing of Newburgh, Prof. Bailey of West 
Point Military Academy, and to Mr. Wm. Cooper, Mr. Abraham 
Halsey, Prof. Eaton, Mr. R. J. Brownne, and Mr. John Carey, 
of New York ; many of whom have also furnished us with 
plants from different portions of the United States. 

For those of Pennsylvania and New Jersey, &c. our chief 
contributors are Dr. Pickering and Mr. Durand of Philadelphia, 
and Dr. Darlington of West Chester, Pennsylvania. From 
Virginia, a small collection has been received from the Rev. Prof. 
Ruffner. 

For plants from North Carolina we are chiefly indebted to 
the Rev. Mr. M. O. Curtis, to the late Mr. Von Schweinitz^ 
from whom we also received many plants from other parts of 
the United States, and to the late Mr. Croom, who also made 
very interesting collections in Florida. 

From South Carolina and Georgia we have received interest- 



Xll PnEFACE. 

ing contributions from the late Mr. Elliott, Major Le Contb, 
the late Mr. Lewis Le Cpnte, Professor Gibbes of Charleston, 
Dr. BoYKiN,now of Columbia, Georgia, the late Dr. H. Loomis 
of Macon, and Dr. Bacon of St. Mary's, Georgia, 

From Middle Florida, Dr. A. W. Chapman of Mariana has 
very fully supplied us with the plants of that region, and many 
have also been comniunicated by Dr. Alexander ; while from 
Southern and Eastern Florida we have received interesting 
collections from Dr. Leavenworth, Dr. Burrows, Dr. Hulse, 
and Lieut, Alden of the United States Army ; and Dr. John 
F. Baltzell has sent many specimens from Apalachicola. A 
portion of the plants collected by the late Dr. Baldwin were 
communipated to us through the late Mr. Schweimtz ; but his 
original herbarium is incorporated in tliat of the Academy of 
Natural Sciences, Philadelphia. The Rev. Mr. Bennett of 
Geneseo, New York, presented us with many plants collected 
by himself during a residence at Key West, and we have re- 
ceived a nearly complete and excellent set of the plants of that 
island from Mr. J. L. Blodgett, which however reached us at 
too late a period to receive notice in this volume. 

From Alabama we have a large number of plants collected by 
Dr. Gates ; and others have been received through the kindness 
of Dr. Fletcher and Dr. Jewett of Mobile. 

From Louisiana the chief contributions have been received 
.from Dr. Ing alls of New Orleans, Dr. Riddell of New Orleans 
(from whom we have also received many plants of Ohio), Dr. 
Hale of Alexandria, and Prof. Carpenter of Jackson. From 
this State, and also from Arkansas and the borders of Texas, we 
have received interesting collections from Dr. Leavenworth : 
and Dr. Pitcher of Detroit, formerly of the United States Army, 
furnished us with a very rniportant suite of Arkansas plants. 

From Tennessee, Dr, Currey has sent us interesting plants : 
from Kentucky we have received excellent and extensive col- 
lections from Prof Short, Dr. Peter, and from the late Mr. H. 
H. Eaton : from this State also, and from other districts, we 
have received many specimens from Mr. RAFiNEsauE. 

From Illinois, Mr. Buckley has sent us large collections ; and 



PREFACE. xiii 

to him we are al^o indebted for many plants from the mountains 
of Virginia, and from Alabama. 

From Indiana, Dr. Clapp of New Albany has supplied us with 
many interesting plants. 

From Ohio, Mr. T. G. Lea, Mr. Wm. S. Sullivant, Mr. 
John Samples, and Dr. Paddock, are the chief contributors. 

From Michigan, Dr. Houghton and Dr. Wright have fur- 
nished us with numerous plants : to the former we are under ad- 
ditional obligations for a parcel of plants collected towards the 
sources of the Mississippi. From the same region we have an 
interesting collection made by Major D. B. Dou<3lass during the 
Expedition of Gov. Cass. 

To Dr. Pitcher we are also indebted for many plants collected 
in the northern part of Michigan, the shores of Lake Superior, &c. 
From Milwaukie, Wisconsin Territory, we have received a col- 
lection of plants from Dr. Lapham. To Dr. Holmes of Mon- 
treal, Mrs. Percival, Mr. and Mrs. Sheppard, and Mr. McCrae, 
we are indebted for numerous plants from Canada. 

The collection made by Dr. Edwin James in Major Long's 
Expedition to the Rocky Mountains, of which an account has 
been given in the Annals of the Lyceum of Natural History, 
has been very useful to us. 

The authors venture to hope that their obliging correspondents 
will still continue to render their assistance in the farther prose- 
cution of this work, by sending the rarer plants of their res- 
pective districts, with such notes and observations as they may 
deem important. 

Since the publication of the earlier portions of this volume, our 
opportunities for examining the herbaria of original authors have 
been very much extended ; and the necessary corrections and 
changes we have been obliged to make on this account, together 
with some additions from works recently published and from 
materials since received, are given in the appended Supplement. 
We trust these investigations will give this work an important 
value in respect to the authenticity of the specific names, and that 
future changes of the kind will not be to any considerable extent 
necessary. 



XIV PREFACE. 



A complete index of the genera and species, and an enumera- 
tion of all the works which relate to North American Botany, or 
are cited in this work, will be given with the concluding volume, 
and likewise, if space permit, some general observations respect- 
ing the geographical distribution of North American plants. 
A connected notice of those plants which are important on ac- 
count of their active or medicinal properties or economical uses, 
will also be added. 

New-York, June 1st, 1840. 



*** The exclamation point is used after the manner in which it is employed 
by De Candolle and other modern botanists, to indicate that we have seen an 
authentic specimen of the author, or from the locahty cited. When the dash is 
omitted after the character of a species, the description is derived from the author 
whose name immediately follows : when the dash is inserted, wc are alone respon- 
sible for the description. The abbreviations of the names and works of authors 
are mostly those in common use, and will be generally understood : they will, 
however, be fully explained at the close of the work.

FLORA 



NORTR AMERICA 



I. CORMOPHYTA. Endlicher. 

Dicotyledones, Monocotyledones, and Acotyledones in partj Juss. 

Plants consisting of a root and stem growing in op- 
posite directions, composed of regular cellular tissue 
traversed (except in the very lowest forms) by woody 
fibre and vessels. Stem increasing in size either at the 
apex and circumference simultaneously, or at the apex 
solely, producing huds^ and (with few^ exceptions) dis- 
tinct leaves at definite points and in regular order : the 
cuticle usually furnished with stomata. Propagation 
effected by means oi Jioiocrs and seeds in the higher 
forms, and of spoi'es in the lower. 

Class I. EXOGENOUS OR DICOTYLEDONOUS 
PLANTS. 

Flowering plants.— Stem with a distinct bark and pith, sepa- 
rated from each other by an interposed zone consisting of woody 
fibre, ducts, and spiral vessels : increase in diameter effected by 
the successive deposition, between the old wood and the bark, of 
new woody and cortical matter, which in perennial trunks is 
usually arranged in concentric zones, and traversed by medullary- 
rays. Leaves furnished with stomata, commonly articulated with 
the stem, their veins branching and reticulated. Floral enve-

2 ANALYSIS OF POLYPETALOUS ORDERS. 

LOPES commonly arranged in a quinary (sometimes binary or 
quaternary, but very rarely in a ternary) manner, sometimes in- 
complete or wanting. Ovules enclosed in a pericarp, fertilized 
by the action of pollen through the medium of a stigma, and 
finally becoming seeds. Embryo with 2 (rarely more) opposite 
cotyledons ; the radicle in germination elongating directly into a 
root. 

Section I. POLYPETALOUS EXOGENOUS PLANTS. 

Thalamiflorse and Calyciflorse, DC. 

Floral envelopes consisting of both calyx and corolla ; the latter 
composed of distinct petals.*

* The student should bear in mind that the division of Exogenous plants into 
Polypetalaj, Monopetalfe, and Apetalai, however convenient, is in a considerable 
degree arbitrary ; and that polypetalous orders often contain apetalous genera and 
species ; the petals, moreover, arc occasionally mo^e or less combined.

tall I March-April. — Plant from 4-12 inches high, slender, clothed with a 
loose hairy pubescence. Leaves variable in the breadth of their segments 
and lobes, sometimes tripartite and very narrow. Flower an inch, some- 
times an inch and a half in diameter : sepals white, often tinged or spotted 
with purple; the outer ones (6-8) thicker; the others petaloid, often al- 
most linear. Head of carpels cylindrical-oblong, woolly. The flowers in P. 
are smaller and greenish, and the head of carpels cylindrical. — We are un- 
able to discover any character that will distinguish this species from A. de- 
capetala, Linn, of S. America. Hooker and Arnott (in hot. of Beechey^s 
voy. p. 4. t. 1.) have indeed shown that the latter species sometimes bears 
several flowers on each scape, and hence they place it in the section Anem- 
onospermos. In our Chilian specimens, however, the scapes are only 1- 
flowered, as usually described ; and A. St. Hilaire (ft. Bras, merid. 1. p.

erect. Stamens foAV, as long as the sepals. Filaments conspicuously dilated. 
Ovaries 8-10 (//«o/f.) (5-6, DC.) ovate gibbous; the persistent style ^ the 
leno-th of the ovary. Hook. This plant was described by De Candolle Irom 
specimens in the herbarium of Michaux. The locaUty is not recorded, nei- 
ther is the plant described in Michaux's Flora. Hooker asks whether it 
may not be a state of T. dioicum ; but that species has remarkably slender and 
scarcely dilated filaments, and linear mucronate anthers. 

2. T.JiUpes: polygamous (?) : carpels semi-obovate, compressed, striate, 
each on a slender stipe, nearly its own length, acute ; style none ; leaves 
biternate ; petiolate ; leaflets roundisli, obtusely 3-5-lobed, ^laucous beneath. 

Linville, North Carolina, Mr. Chirtis !—V\d.i\i 2 feet or more in height, 
very smooth. Leaves thin, on petioles an inch long, exstipellate. Panicle 
corymbose, loose and capillary. Flowers not seen. Carpels 4-6, widely 
spreading, membranaceous, marked Avith several prominent branching veins, 
acute, and tipped with a minute stigma, but not rostrate ; the base tapering 
into a long almost capillary stipe. Seed much smaller than the cavity.— This 
species, the flowers of which we have not seen, is nearly related to T. clava- 
tum ; but differs in the veined carpels, the entire absence of the style, and the 
long slender stipe. 

** Carpels ovate or oblong, ribbed, sessile or slighily stipilatc : sepals caihicous.

capillary and nearly of the same thickness throughout ; anthers yellowish. 
Fertile flowers with 6-8 stamens. Ovaries 6-10.— The variety k we have 
only seen in fruit. The stipes are more than half the length of the strongly- 
ribbed carpels ; and the persistent style is as long as the stipe. In other 
respects the resemblance to T. dioicum is very striking.— T. purpurascens, 
DC. is referred to this species; but we are not certain that his plant is the 
same as that of Linnaeus.

bricated. Stamens indefinite, distinct, hypogynous : filaments very 
short : anthers adnatc, introrsc. Ovaries several in a single row, or 
numerous and spicate in several rows, on a torus raised above the sta- 
mens : styles short or none : stigmas simple. Fruit consisting of 
numerous 1-2-seeded carpels, follicular or baccate, or woody, or fleshy, 
aggregated or connate in a strobiliform manner upon the clongat- 
ed torus ; sometimes samaroid. Seeds anatropous, suspended or as- 
cending. Embryo minute, at the base of fleshy homogeneous albu. 
men. — Trees or shrubs. Leaves alternate, entire, (pubescent when 
young) mostly minutely punctate with transparent dots, coriaceous, 
with convolute caducous stipules. Flowers rarely diclinous, solitary, 
usually large, fragrant. 

The presence of pellucid dots in the leaves of WintcrfxceEe, and their absence in 
Magnoliacea;, is considered a chief mark of distinction by those autliors who view 
the two orders as distinct. These dots, liowever, exist in all our Mas^nolias, as well 
as in the exotic forms we have examined, and may he ob'served witli a lens of very 
moderate power (if the leaves be too coriaceous at least in tlie petals) quite as readi-

The order Schizandracccc, established by Bkime in his splendid Flora Javae, al- 
though indicated in an earlier work, is founded upon Schizandra and two Asiatic 
genera, viz : Sphserostema (which diflers from the former chiefly in its indefinite 
stamens,) and Kadsura, Juss., which was formerly referred to Anonacere. 



Order V. MENISPERMACE.E. Juss. 

Flowers dioecious, rarely moncecious or polygamous. Sepals usually 
in a double row, 2-4 in each, imbricated in testivation, deciduous. 
Petals 1-8 (usually equal in number to the sepals), h5'pogynous, dis- 
tinct or sometimes united, rarely none. Stamens distinct or mona- 
delphous, equal in number to the petals and opposite them, or 2-4 times 
as many : anthers adnate (extrorse or introrse !), or innate and con- 
sisting of 4 globose lobes, or with the cells horizontal and placed end 
to end, opening longitudinally. Ovaries usually several, distinct or 
rarely united. Drupes baccate, 1-seeded, oblique or lunate, or incurv- 
ed so that the apex and base are brought into contact ; the nut (endo- 
carp) bony, and often tuberculate on the broad margin. Seed hetero- 
tropous, conformed to the cavity of the nut. Embryo curved, included 
in the rather thin fleshy albumen : radicle directed towards the style. — 
Flexible and climbing shrubs or sutfruticose plants. Leaves alternate, 



Menispermum. MENISPERMACEiE. 47 

without stipules, simple, palmately veined. Flowers minute, in ra- 
cemes or panicles. 

The true structure of the fruit in this order, is f^iven by A. St, Hilairc, in his 
Flora Brazihiu Mcridionalis. After fecundation tlie ovary begins to grow on one 
side, and curves until, in most cases, the summit is brought close to the base. Tlic 
fruit, Avhich is a true drupe, has an obovatc or subglobose form, and the nut is curv- 
ed like a horse-shoe, so that -when it is cut transversely it appears to be ^-celled, a 
false dissepiment being formed by the bending together of the two ends of the fruit. 
The shell or cndocarp is often mistaken for the testa of the seed, the proper integu- 
ments being membranaceous. According to De Candolle, the anthers are extrorse ; 
but they arc certainly introrse in Menispermum Lyoni, and in some species of 
Cocculus.

what coriaceous when mature : petioles 1-4 inches long. Flowers sometimes 
polygamous? Sterile Fl. in compound racemes which are often 3-parted to 
the base, greenish-white. Bracteoles mostly sohtary. Sepals 6, orbicular, or

each. Stamens 6: filaments thickened at the summit, on which is borne the 
didymous anther-cells, appearing like 4 approximated spherules. Drupe red, 
as large as a small pea, compressed ; the nut curved into nearly a complete 
ring, notched on the margin. Seed terete, filling the circular cavity of the

Leaves 3-4 inches long, rather broader than wide, with 3-5 angular lobes. 
Flowers small, greenish-yellow ; the sterile ones in paniculate supra-axillary 
racemes : pedicels about a hne long, bracteolate. Sepals commonly 4-5, obo- 
vate-oblong. Petals much smaller than the sepals, orbicular, obtusely cuneate 
at the base. Filaments scarcely thickened at the summit : anthers of 4 
spherical lobes. Drupe stipitate, about one-third of an inch in diameter, nearly 
black when mature, pruinose, curved so that the style and base are nearly in 
contact ; pulp small in quantity. Nut much compressed, forming a nearly 
complete ring. Seed terete, annular. Embryo linear, in the axis of a 
fleshy albumen, and nearly of the same length.

Near New Orleans, Dr. Ingalls .' Arkansas, Nuttall ! Kentucky and 
Tennessee, Pursh. — Stem climbing, about twenty feet long (PitrsA,). Leaves 
3-7 inches in diameter, sparsely hirsute on the veins underneath ; the sinuses 
commonly rounded, and often extending beyond the centre of the lamina. 
Racemes shorter than the petioles, supra-axillary ; the pedicels 1-4-flow^ered. 
Sterile Fl. Bracteole at the base of the sepals minute. Sepals obovate- 
oblong, obtuse. Stamens shorter than the sepals : filaments compressed, ra- 
ther thick ; anther cells linear-oblong, introrse, the cells parallel with the axis 
of the filament. Fertile Fl. Sepals as in the sterile flowers. Abortive 
stamens half the length of the sepals ; the spurious anther cells oblong and 
somewhat diverging. Ovaries oblong, straight: stigmas sessile, fimbriate. 
Drupe exactly oval, nearly an inch long (black, Pursh), compressed contrary 
to the sutures. Nut deeply excavated in front, convex and smooth on the 
back. Albumen fleshy and oily, in the fonn of a shallow cup. Embryo very 
broad, lying in a shallow cavity in the midst of the albumen; cotyledons 
oval, very thin and membranaceous, at length diverging. — The back and front 
layers of albumen at length become soldered together, so that the shallow 
cavity is divided into two cells, in each of which a cotyledon is lodged ; as in 
Cocculus suberosus, DC. figured by Gsertner {Fr. 1. i. 70. /. 1.), and as de- 
scribed by Wight & Arnott {Prodr. ft. Penins. hid. 1. p. 11). We have 
seen the ripe fruit of this species only when deprived of its pulp. In the 
half-grown state it is ovate, nearly straight, and slightly pointed at the summit 
with a very short style. When fuUy grown the style appears to be still 
nearly terminal. The shell is smooth, exactly oval, with a large cavity in

Menispermum smilacinum, DC. sijst. 2. p- 5H (Cissampelos smilacina, Linn.*?) 
seems to be only M. Caiiadense with smoother leaves and more simple racemes than 
usual. The number of petals is very inconstant in the latter species, there being 
sometimes only four. The figure in Catesby (^Carol. 1. t. 51.) is probably Cocculus 
Carolinus, and is certainly not a Menispermum. 



Order VI. BERBERIDACE7E. Vent. ; R. Br. 

BerberideK & Podopliyllacese of Authors. 

Sepals deciduous, 3-4-6, imbricated in two rows, often calyculate 
with petaloid scales. Petals hypogynous, as many as the sepals and 
opposite them ! or twice as many, frequently appendaged or glandular 
at the base within. Stamens as many as the petals and opposite them ! 
(twice as many in Podophyllum) : filaments short : anthers adnate, 
extrorse, opening by recurved valves, (i. e. the face of each cell sepa- 
rating elastically from the connectivum from the bottom to the top, 
like a valve) except in Podophyllum. Ovary solitary, simple : style 
continuous, often somewhat lateral or oblique : stigma orbicular or 
peltate. Fruit baccate or capsular. Seeds 1 or few, rising from the 
bottom of the cell, or numerous and attached to the ventral suture in 
one or more rows, sometimes arillate. Embryo in the axis or near 
the base of fleshy or horny albumen. 

Tribe I. BERBERIDE^. 

Embryo in the axis, and occupying nearly the whole length of i\\e 
albumen : radicle long : cotyledons flat, elliptical. — Shrubs. Leaves 
compound or reduced to a single leaflet, often stipulate. Flowers 
yellow. Filaments irritable.

sessile ; the margin serrulate with 6-8 distant, often inconspicuous, mucro- 
nate teeth. Raceme 5-8-floAvered, nodding : flowers smaller than in B. vul- 
garis; fruit smaller and much shorter. — This indigenous species, very dis- 
tinct from B. vulgaris, with which it has been in some degree confounded, is 
probably a native of the Southern States only ; the Barberry of the New Eng- 
land States and, doubtless, of Canada, being the European species, and cer- 
tainly not indigenous. Our species was first noticed, apparently, by Marshall, 
who states that he has a different species of Barberry growmg near New 
River, Virginia. Original specimens, collected and named by Pursh, exist 
in the herbarium of the late Prof. Barton, now deposited in the rooms of the 
American Philosophical Society, Philadelphia.— B. emarginata, Willd., a

Near the coast from lat. 40 "-49', jMenzie.'^, Doui^las, Ur. iScautcr ! April. 
— An under-shrub, 2-5 feet high, branching; tlie branches often prucunibeni. 
Leaflets li-3 inches long, obscurely reticulated on both sides, the veins ;dl 
rising from the midrib. Petals connivent, the innermost bifid at the ape.x. 
Berries dark purple. — This species, as we consider it, is liable to much varia- 
tion in its foliage ; and we should incline to follow the authority of Lindley 
and of Nuttall (who has recently enjoyed the opportunity of examining these 
plants extensively in their native situations), and to separate our var. «. as a 
distinct species, did not our specimens of /A communicated by Mr. Nuttall 
appear manifestly to connect it with )., the B. A([uifolium of tlie region near 
the Pacific coast. The former is moreover the plant originally brought to 
the United States by Lewis, and described and figured (chieHy) by Pursh, 
and cultivated in gardens, under the name of B. Aquifolium ; so that it ought, 
in accordance with the rule in such cases, to retain the original name. Pursh 
erroneously describes the berry as 3-celled, with a 3-lobed stigma; but his 
figure of the fruit is manifestly taken/from some very diffcreiit plant.* 

4. B. pinnata (hagasca): leaflets 4-5 pairs, the lowest pair approximate to 
the base of the petiole, ovate-lanceolate, repandly dentate with 4-5 teeth on each 
side; racemes erect [nodding in Jig. JJeless.], very much crowded. JJC.

" Western coast oi North America near Monterey [California] and Nootka, 
Nei ex Lagasca; and in New Spain, Humb. ^ Bonpl.^^ JJC. I. c. — The 
plant from Nootka is doubtless B. Aquifolium, as Lindley suggests. All our 
specimens from Oregon have the lower pair of leaflets at some distance from 
the base of the petiole ; in which, as in the less crowded racemes, &c. they 
wholly disagree with the character of De Candolle and the figure of Deles- 
sert ; and as Hooker changes the specific phrase of his B. pinnata in these 
particulars, we have the more confidently referred the Oregon plant to B. 
Aquifolium. 

5. B. nervosa (Pursh): suffruticose ; leaves elongated ; leaflets 5-S pairs 
(the lowest not approximated to the base of the petiole), ovate or oblong, 
acute, repandly dentate with thorny teeth, 3-5 nerved from the base, the 
nerves reticulated ; racemes simple, elongated ; pedicels very short ; filaments 
2-toothed. — Pursh, fl. 1. p. 219. t. 5. (excl. the flowers, which belong to B.

inches long : flowers larger than in B. Aquifolium. Peduncles and petioles 
surrounded at the base with numerous dry convolute and pungent glumaceous 
bracts. Berries deep blue. — Pursh, Avho has made sad work in his figures 
of Berberis, added the flowers of B. Aquifolium to the leaves of the present 
species, and thus led De Candolle into mistake.

Along rivulets in high mountains, Virginia to Georgia ! North Carolina, 
Mr. Curtis ! (in fruit only)— Stem 1-2 feet high. Seeds reddish : testa 
membranaceous : hilum somewhat unilateral.— De Candolle, in describing the 
seed, says, " Embryone recto tenui," which is incorrect. Decaisne, {Ann. 
sci. nat. (2. ser.) 2. p. 359,) who also examined Michaux's specimen, states 
that the embryo occupies about a third of the length of the albunien. It is 
really, however, much smaller than this, although the little cavity in Avhich it 
is situated is sometimes prolonged to near the centre of the albumen, a cir- 
cumstance which may possibly have misled the observers. In this, as in 
some other genera, the peculiar disposition of the veins of the pericarp rnay 
be observed which Morren & Decaisne noticed in Epimedium, and which 
led these botanists to consider the ovary of Berberidaceee as compound. This 
peculiarity admits, however, of easy explanation on the supposition that the 
carpel is formed of a palmately veined leaf.

it agrees with the latter in its definite stamens, and with the former in the 
foliage and floral envelopes, dilated filaments, &c. The torus is somewhat 
like that of Chryseis on a very small scale.

Fischer &. Meyer, who examined the living plant raised from seeds sent 
from the Russian settlement in California. The 3 outer petals, according to 
these botanists, are golden yellow with a transverse white band ; the inner 
ones white with pale yellow claws.

P. leiocarpum, Fisch. &■ Meyer, is nothing more than an accidental variety ;

others with a few hairs. — This anomalous genus is almost exactly interme- 
diate between Papaveracese and Kanunculacese. 



Order XIII. FUMARIACE^. DC. 

Sepals 2, small, deciduous. Petals 4, hypogynous, cruciate ; one or 
both of the two outer ones saccate or spurred at the base ; the inner 
pair cohering at the callous apex, and enclosing the anthers and stig- 
ma. Stamens 6, hypogynous : filaments in two parcels, placed oppo- 
site the outer petals, dilated, distinct or usually diadelphous: anthers 
adnate, extrorse ; the middle one of each parcel 2-celIed ; the lateral 
ones 1-celled. Ovary composed of 2 united carpels, l-celled, with 2 
parietal placentae : style filiform : stigmas united, often lobed or cuspi- 
date, alternate with .the inner petals. Fruit either an indehiscent 1— 
2-seeded nut, or a 2.valved many-seeded pod-shaped capsule ; the 
valves at length often separating from the persistent filiform placentae . 
Seeds anatropous or partly campulitropous, shining, arilled : albumen 
fleshy. Embryo in the genera with indehiscent fruit minute and ex- 
centric, in the others longer and more or less curved or circinate. — 
Annual or perennial glabrous and often glaucous herbs, with a watery 
juice. Leaves alternate, ternately or pinnately divided, exstipulate. 
Flowers racemose or cymose, purple, white, or yellow. 

The two lateral stamens of each pai'cel, having unilocular anthers, may be con- 
eidered as half-stamens, formed by the division of the two stamens which correspond 
to the inner petals : the true number in the order, according to this view, being four, 
one to each petal. — Lindley is inclined to regard the sepals as bracts, and the outer 
petals as sepals : but their analogy with Papaveracese (from which Lindley, follow- 
ing Bernhardi, distinguishes them only as a suborder) does not favor this view.

the length of the petals: pedicels strongly curved downwards after flowering. 
Stigma capitate, apiculate. Hook. — We are suspicious that both this and the 
succeeding species will prove to be identical w^th C. pseonisefolia of Siberia 
and Kamtschatka, which extends, according to Chamisso, nearly to America; 
but the question can only be decided by comparison with the original speci- 
mens in Willdenow's herbarium. The raceme, according to Hooker, is 
more compound in that species than in C. Scouleri; but Chamisso remarks 
{Linntea, I. p. 563.) that the racemes in his specimens are more commonly 
simple.

from C. rhomboidea, 7?C, and that the diffcronce in the appearance of the 
two plants depends on the place of growth. The former grows in cold se- 
questered springy places, where it does not readily bear fruit early in the sea- 
son; and as summer advances, it becomes slender, procumbent, and loses its 
tubers at the base of the stem. Sir WilUam J. Hooker has accurately figur- 
ed and described both forms of the plant ; but having seen the two pass into 
each other, we are obliged to dissent from our friends Avho consider ih«m dis- 
tinct. The var. y. takes the place of the ordinary form in Canada, the wes- 
tern part of the State of New York, and the Western States.

the racemes terminating short assurgent branches, and the pedicels being 
greatly elongated, so as to resemble scapes.

high. Racemes sometimes nearly a foot long. Flowers large, showy- 
Calyx persistent; segments triangular-acuminate. Stamens equal. — This 
species was originally described from specimens collected by Capt. Wyeth 
exhibiting the floral leaves only, which are narrowly lanceolate and very 
acute at each end. Mr. Nuttall obtained complete specimens in his recent 
journey. 

3. C. aurea : " glabrous ; leaves 3-5-foliolate ; leaflets oblong-lanceolate, 
acute at each end, entire [sepals united at the base only] ; petals oblong- 
elliptical, nearly sessile (golden-yellow); stamens equal; pods linear, [short]

4. POLANISIA. Raf. injour.phys. (1819) f». 98. 

Sepals distinct, spreading. Petals 4. Stamens 8-32: filaments filiform 
or dilated at the summit. Torus minute (often nectariferous). Pod linear, 
sessile or nearly so. — Annual herbs with the habit of Cleome, mostly glan- 
dular, with a heavy odor. 

§ 1. Torus hearing a short fleshy nectary or gland next theupper sepal:

Polanisia proper. 

Polanisia proper, as is indicated by R. Brown (in app. to Denh. <§- Clapp.p. 15), 
consists of two American species solely, viz: P. graveolens and the closely allied 
P. uniglandulosa of Mexico. The close resemblance between these two species was 
iirst noticed by Nuttall. (See gen. JV. ^m. pi. 2. p. 74.) A third species exists in the 



CiusTATELLA. CAPPARIDACE/E. 123 

herbarium of Maj. Le Conte, which approaches in the foliage and the very unequal 
petals to Cristatella; a curious genus, which should perhaps be considered a section 
of Polanisia, if indeed all these genera ought not to be restored to Cleome, accord- 
ing to the opinion of Brown. 

L P. graveolens (Raf.): viscidly pubescent and glandular; leaves 3-loli- 
olate; leaflets (and bracts) oblong, shorter than the petiole; sepals (purplish) 
soraewhat unequal; petals cuneate, emarginate; stamens mostly 10 or 11 ; 
style shorter than the ovary ; pods broadly lanceolate, turgid, attenuate at the

This genus, with the character somewhat modified, may possibly be found to in- 
clude several tree-like S. American species of Cleome, (of the section Pedicellaria), 
and should perhaps be viewed as a section of Cleome. 



Order XYI. RESEDACEtE. DC. 

Sepals 4-6, somewhat united at the base, unequal, herbaceous, per- 
sistent : aestivation open. Torus short, bearing a flat and rounded 
glandular hypogynous disk, which is produced posteriorly (i. e. next the 
axis) between the petals and the .stamens. Petals 4-6 (or by abortion 
fewer), open in aestivation, deciduous, unequal, the posterior ones lar- 
ger, the anterior ones often abortive or sometimes wanting ; claws 
usually broad and thickened, nectariferous within ; the lamina often 
lacerate or palmately parted. Stamens 8-20, rarely 3, inserted on 
the disk : filaments erect : anthers oval, fixed by the middle, introrse. 



Elumia. RESEDACEyE. 125 

Ovary l-celled, 3-4 lobed, composed of 3-4 united carpels, wliich arc

ceae are exclusively natives of the region surrounding the Mediterranean. — Reseda 
luteola(the Dyer's Rocket, or Yellow-weed, used in dying woo:len stuffs yellow) is 
found along road-sides in portions of the western part of the State of iSew-York, but 
is hardly naturalized.

Stamens 6-8, hypogynous : filaments combined into a tube which is 
split on the upper side and more or less connate with the claws of the 
petals, free at the summit : anthers innate, usually l-celled,* opening by 
a terminal pore. Ovary compressed, formed of 2 (anterior and poste- 
rior) united carpels, 2.celled with the placenta in the axis, sometimes

men, straight or very slightly curved. — Herbaceous (all the N. American 
species) or shrubby plants ; the roots very bitter and often milky. 
Leaves exstipulate, entire, generally alternate or sparse, the lower 
ones not unfrequently verticillate. Flowers usually racemose or 
spicate : pedicels l-3.bracteate.

date, rose-color and green, of a firm texture, generally twice as long as the 
mature fruit. Style as in the preceding species. Seeds giayish-black. — 
Much more common than the preceding species, from which if is easily dis- 
tinguished by its broader and thicker wings, and minute caruncle, which is 
scarcely one-fifth the length of the seed. This is P. sanguniea of most 
North American botanists ; but whether it is the plant of Linnaeus can only 
be determined by consulting his herbarium.

Suborder KRAMERIE/E. Mart. 

Sepals 5, or rarely 4, more or less irregular, much spreading, colored, 
deciduous, in aestivation imbricated in a triple series; the two outer 
ones anterior and posterior ; the two intermediate ones lateral and 
alternate with the exterior pair ; and tiie innermost usually smaller, 
situated either to the right or left of the posterior exterior sepal, some- 
timcK wanting. Petals 5, or rarely 4, hypogynous, smaller than the 
sepals ; the three superior with long and slender claws (the lamina 
sometin>es abortive), severally alternating with the two (outer and 
inner) posterior and the lateral sepals ; the claws sometimes united 
into a slender column, which alternates with the two posterior sepals 
when both are present, or is placed opposite to the exterior sepal when 
the other is abortive ; the two lower petals (scales, abortive stamens ? 
Kunth) opposite the lateral sepals (in K. cistoidea, ex Hook. 4' Arn. and 
in K. lanceolata !), or alternating with these and the anterior sepal 
(ex A. St. Hil.), sessile, fleshy, much smaller than the others and remote 
from them. Stamens 4, hypogynous, naore or less unequal, declined ; 



134 KRAMERIEiE. Kkameria; 

two usually lonjrer, alternate with the lateral unguiculate and the 
lower or fleshy petals ; and two close together, alternate with the supe- 
rior and the lateral petals : filaments thick, distinct, or the interme- 
diate ones united, or (in K. lanceolata) all more or less united : an- 
thers innate, fleshy, somewhat conical, 2-celled, opening at the apex 
by a single or douhle pore. Ovary 1- (or incompletely 2-) celled, 
densely hairy, gibbous : style subulate, ascending : stigma minute : 
placenta posterior or next the upper petal : ovules 2, pendulous from 
near the summit of the cell. Fruit between woody and leathery, glo- 
bose, glochidate, indehiscent, 1-celled, 1-2-seeded. Seed roundish, 
ovate, anatropous, with a membranous testa : albumen none. Em- 
bryo straight : cotyledons roundish, plano-convex, fleshy. — Spreading 
or procumbent under-shrubs, much branched from the base, silky or 
hirsute with simple hairs : the root astringent and very bitter. Leaves 
alternate, exstipulate, simple or rarely 3-foliolate, entire. Peduncles 
terminal and axillary toward the summit of the branches, sometimes 
more properl}^ racemed, 1-flowered, 2-bracteolate in the middle. 

Hooker and Arnott {hot. Beeckey^s voij. p. 9. t. 5. 1831), in their elaborate account 
of the structure and affinities of Krameria, have corrected an important error in the 
character given by St. Hilaire {riiem. mus. 17. t. 31, and 19, p. 336 ; 4- in ji. Bras, 
merid.; copied also in Lindl. nat. syst. ed. 2. 1836.), wiio describes the three ungui- 
culate petals, and consequently the sepal accompanying the smaller internal one, as 
inferior or anterior; the structure according to this view being nearly the same as in 
Polygalaceas. Hooker and Arnott remark that they are borne out in tlieir view of 
the position of the parts of the tlower (which supposes an inversion of the com- 
mon arrangement in Polygalacea; to take place), by Ruiz and Pavon, Jussieu, and 
Kunth; and their view is fully sustained by the structure of K. lanceolata, although, 
on account of the twisting of the peduncles, the petals often appear, at first sight,"to 
be anterior. St. Hilaire is equally mistaken in considering the side of the ovary 
which is turned away from the ' lower' (that is, according to his view, the ungui- 
culale) petals as placentiferous: but the affinities suggested by Hooker and Arnott 
are not borne out by the correction, unless the ovary is proved to be monocarpellary, 
which is probably not the case. The innermost sepal may either be situated on the 
left of the exterior upper sepal (as in K. grandiflora figured by St. Hilaire ; the 
flower being brought into its true position), or more commonly on the right : in 
K. lanceolata we find this sepal sometimes dextral and sometimes sinistral.

1. K. lanceolata (Torr.): branches mostly procumbent, many-flowered; 
lower cauline leaves oblong-lanceolate or obovate-lanceolate ; the others nar- 
rowly linear ; peduncles hibracteate above the middle, longer than the leaves ; 
sepals 5, nearly equal ; unguiculate petals 3, the claws united their whole

branches slender, often a foot or more long. • Lower cauhne leaves about f 
of an inch long, and 2 lines broad, sometimes obtuse ; those of the branches 
usually longer. Peduncles on the prostrate branches secund, often twice the 
length of the leaves, forming as it were loose leafy racemes. Sepals purple

within, ovate-lanceolatP ; the inner superior one mostly seated on the left. 
Upper petals a little shorter than the sepals; the claws united into a linear- 
fihtbrm column; laininai small, roundish-obovate, distinct, equal, of a rather 
firm texture : lower petals scarcely longer than the ovary, glabrous. Sta- 
mens shorter than the upper petals : filaments sometimes monadelphous at 
the base, sometimes united almost to the summit: anthers attenuate above, 
the apex produced into a short somewhat dilated membranaceous tube. 
Ovary densely hirsute and spinulose, imperfectly 2-celled in the youngest 
state by the projection of the placental ridge. Style rigid, quadrangular, a 
little declined. Immature pericarp 2-seeded ; one of the seeds perhaps at 
length abortive. — Apparently more nearly allied to K. linearis, Poir. (K. 
pentapetala, Ruiz ^ Par.), which has (according to the figure in the Flora 
Peruviana) the three upper petals united throughout ; the compound lamina 
being merely 3-toothed. In a single flower of our species we observed the 
suppression of one of the upper petals, and in another case two of them 
were apparently wanting. 



Order XVIII. VIOLACE^. DC. 

Sepals 5, persistent, distinct or slightly united, and often auricled 
or produced at the base, imbricated in aestivation, the anterior and 
two posterior being exterior, and the two lateral ones interior. Pe- 
tals 5, alternate with the sepals, hypogynous, marcescent or deciduous, 
on short claws, commonly unequal, the superior one (which by the 
resupination of the flower becomes inferior) usually spurred or sac 
cate at the base : aestivation obliquely convolute. Stamens 5, alter- 
nate with the petals, inserted on the hypogynous disk or torus : an- 
thers adnate, introrse, 2-celled, opening longitudinally : filaments di- 
lated, elongated beyond the anthers ; two of them generally furnished 
with a spur-like appendage or gland at the base. Ovary composed of 
3 united carpels, 1-celled, with 3 parietal placentae opposite the outer 
sepals : style usually declined, with an oblique cucullate stigma. 
Capsule l-celled, 3-valved, loculicidal, bearing the many- (rarely few-) 
seeded placentae on the middle of the valves. Seeds anatropous, 
usually with a distinctly marked chalaza, and a crustaceous testa. 
Embryo straight in the axis of fleshy albumen. — Herbs or shrubs. 
Leaves simple, petioled, alternate or rarely opposite, with an involute 
vernation : stipules persistent or marcescent. Flowers axillary.

North America, Michaux, ex DC. — This plant is inserted on the authority 
of De CandoUe, who states that he saw it in the herbarium of the Museum

not a variety of N. orchidiflora. It has doubtless been recorded as a native 
of N. America by mistake.

6-10 inches long, branched from the base, when old decumbent and genicu- 
late. Veins of the under surface of the leaves sometimes pubescent. Flow-

the stem is very short, but at length it throws off prostrate branches, which 
produce tufts of leaves and flowers at the extremity.

Stamens 10-15: anthers innate. Style 1, thick: stigmas 5, connivent, 
fimbriately many-cleft. Capsule membranaceous, indehiscent, but tearing 
open irregularly (5-valved, DC), 1-celled. Seeds numerous (20-30), partly 
immersed in the scrobiculate cellular placenta which fills the base of the cap- 
sule. — A glabrous perennial (yellowish-green) herb. Flowers umbellate at 
the extremity of a slender scape. Leaves (not circinate in vernation) radi- 
cal, rosulate and spreading ; petiole winged and foliaceous, terminating in an 
articulated circular spinulose-ciliate lamina, which is very sensitive, suddenly 
closing when the upper surface is touched. — Vemis^s Fly-trap. 

Arnott places Dionrea in his suborder ParnassicEe; but we prefer to retain it in 
Droseracese proper, with which it agrees more nearly in habii, and from wliicli it 
differs in no important character except in tlie vernation, and in the placenta which 
fills the bottom of the ovary; the style, moreover, is just such an one as would he 
produced liy the cohesion of the rnultifid styles of" some species of Drosera nearly 
to the summit. On tlie oilier hand, it differs from Parnassia in most of the peculiar 
characters of that o^enus, viz.: the peri^ynous stamens, a portion of which are abor- 
tive or transformed, tlie sessile stigmas opposite the placenlte, and the albuminous 
seeds.

obovate, smooth and shining, black, marked witli an inconspicuous raphe. 
Embryo oblong, at the base of the cartilaginous albumen. — '' The sensitive- 
ness of the lamina," according to Mr. Curtis, " resides only in the '3 or 4 
hair-Uke processes of its upper surface, so placed that an insect can hardly 
traverse it M^ithout interfering with one of them ; when the two sides sud- 
denly collapse and enclose the prey, the fringe or hairs of the opposite sides 
of the leaf interlacing like the fingers of the two hands clasped together." 
See the further remarks of Mr. Curtis in loc- cit. 



Suborder PARNASSIE^. Am. (excl. Dion^a.) 

Sepals 5, persistent, imbricated in aestivation ; more or less united 
at the base and coherent with the base of the ovary. Petals 5, some- 
what perigynous, persistent, alternate with the petals: venation sim- 
ple. Stamens, perigynous, persistent, consisting of an outer sterile se- 
ries, somewhat indefinite in number, united in 5 phalanges situated 
opposite the petals ; and an inner series of 5 fertile stamens alter- 
nating with the petals' : anthers fi.xed by the base, introrse. Ovary com- 
posed of 4 united camels, l-celled, with 4 sessile stigmas opposite the 
parietal placentae. Capsule 1-celIed, 4-valved, loculicidal. Seeds very 
numerous, anatropous, with an arilliform winged testa : albumen none. 
Embryo straight, with a slender radicle and minute cotyledons. — Gla- 
brous perennial herbs (growing in wet places.) Leaves mostly radical 
or nearly so, petioled, exstipulate, entire, with obscure converging 
veins. Scapes elongated, 1 -flowered : flower white. 

This suborder, as characterized above, includes the anomalous genus Parnassia 
alone ; which was placed by Jussieu, along with Diosera and Reseda, among " Ge- 
nera Capparidibus affinia;" and is referred to Droseracese by Richard, De Candolle, 
and (as & suborder) by Arnott- to Saxifragacese (with which they agree very well, 
except in the completely syncarpous ovary and the position of the stigmas,) by 
Brown and Liiidley ; to Hypericaceffi by Don ; and (with a mark of doubt) to Tama- 
riscineae by Bartling. The curious scale-like organs terminating in three or more 
threads or seta with glandular lips, are doubtless transformed stamens ; but their 
situation {opposite the petals and exterior to the fertile stamens) as well as their 
structure renders it evident that they are not composed each of a single stamen, as 
has been stated, but of 3 or more, as we have described them. That they are so 
considered by Don, is manifest from the view he takes of the affinity of the genus, 
although the work which contains his remarks is not at this moment before us.

Order XX. CISTACEiE. Juss, 

Sepals 5, persistent ; the two outer ones usually much smallest or 
sometimes wanting ; the three inner imbricated and often somewhat 
twisted in a3stivation. Petals 5 (rarely 3 or by abortion none), hypogy- 
nous, mostly very fugitive, usually crumpled in aestivation and twisted 
in a direction contrary to that of the sepals. Stamens indefinite, or 
rarely kw, hypogynous, distinct : anthers short, innate. Ovary com- 
posed of 3-5 united carpels : styles and stigmas mostly united into 
one. Capsule 3-5-valved, loculicidal, 1-celled with parietal nerviform 
placentae, or imperfectly 3-5-celled with dissepiments proceeding from 
the middle of the valves and bearing the placentae at or near the axis ; 
endocarp often separating from the exocarp. Seeds few or numerous, 
orthotropous (veiy rarely somewhat anatropous). Embryo nearly 
straight or spirally convolute, in the midst of mealy or somewhat cor- 
neous albumen. — Herbs or low shrubs : pubescence simple or stellate. 
Leaves simple and usually entire, opposite or alternate (the lowest 
always opposite), with or without stipules. Flowers perfect, yellow, 
white, or red, showy or sometimes inconspicuous. 

Mr. Spach, in his papnr entitled ' Description of some nciv Cistacece, published in 
the first volume of the Companion to the Botanical Magazine, annouaces the some- 
what curious fact, that a few Cistaceis have anatropous seeds, but without mention- 
ino; in what plants this structure is found. We find anatropous seeds in Helianthe- 
Tnum Fumana, H. procumbens, H. lajvipes, H. junipcrinum, and H. glutinosum 
(which are all the species of the section fimiana of which we have specimens in 
proper state for the examination) ; also in H. alpestre. In the two first-named spe- 
cies the funiculus is adherent only for about half the length of the seed, which is thus 
as it were heterotropous or amphitropous ; in the others it adheres almost to the 
(organic) apex of the seed, but in H. Isevipes and H. glutinosum it may readily be 
separated from the testa. I'he seeds of H. glutinosum, when thrown into water are 
seen to be covered with a very dense coat of mucus, enveloping a great number of spi- 
ral threads which uncoil when the mucus dissolves ; as in CoUomia linearis. 

1. HELIANTHEMUM. Toiirn. inst. t. 128 ; Gc^tn.fr. t. 76 5 DC. 

The two exerior sepals usually much smaller and bract-like, or wanting. 
Petals 5 or rarely 3, sometimes abortive, fugitive. Stigmas 3, large, fimbrio- 
late, more or less united into one. Capsule triangular, 3-valved, few- or 



Helianthemum. CISTACE/E. 151 

many-seeded : placentae filiform, in the axis of the valves or on iniperfuct 
dissepiments more or less projecting into the cell. Embryo indexed. 

The North American species belong to the section Lecheoides, Dwnal ; havine 
the exterior sepals minute, a very short straight style, and strictly parietal placenta;: 
they are almost sufTruticose, with mostly stellular pubescence, and exstipulate slightly 
petioled aUernate leaves, except the lowest, which are usually opposite ; and the evo- 
lution of the (yellow) flowers is centrifugal. Excepting H. scoparium from Cali- 
fornia, and II. Carolinianum, which hardly belong to this section, they dirter 
from the European sjiccics in producing two kinds of (lowers: viz. 1st, Terminal or 
dichotomal flowers, usually preceding the others, on slender pendunclca, with con- 
spicuous petals and numerous stamens. 2nd, Smaller flowers, usually clustered in 
axillary cymes or glomerules, scarcely ever fully expanding, witli minute petals or 
often none, fewer stamens, and smaller and fewer-seeded capsules. The two kinds 
often occur on the same specimens ; but the latter are produced later in the season, 
and in sterile soil often to the exclusion of the others, giving to the plant the appear- 
ance of Lechea, so much so as to have deceived Linnaius, wliose L. major is wel! 
known to have been founded upon such a state of Helianthemum Canadense. Mr. 
Spach has noticed this peculiarity in our species, and separated them as a distinct 
genus under the name of Heteromeris. 

"r*"^!. //. Canadense (Michx.) : stem at first simple ; the primar}'^ or termi- 
nal large and petaliferous flowers few or solitary, on peduncles scarcely longer

calyx ; secondary flowers axillary, very small, nearly sessile, solitary or some- 
what clustered on short leafy branches, the petals very small or none, and 
the outer sepals usually wanting ; leaves oblong or somewhat lanceolate, with 
revolute margins (when dry), and, as well as the sepals and often the 
branches and peduncles, canescently tomentose. — Michx. ! fl. 1. p. 308 ;

as well as more in accordance with the rules of nomenclature, to retairi the 
name L. major for this species ; since it is not only the generally received,

somewhat acute. Petals obovate, a little longer than the calyx. Filaments 
not distinctly polyadelphous. Styles united. Capsule ovate. Elliott. 
Style unusually long. Nuttall. — Among our numerous specimens of Ascy- 
rum from the Southern States, there is not one that agrees in all respects 
with either Michaux's or Elliott's description of this plant. In many respects 
it seems closely allied to the preceding species, especially with the dwarf 
form of the plant so common in New Jersey ; but in that the peduncles are 
never long and reflexed.

Styles occasionally 6 or 7, recurved at the extremity : stigmas capitate. Cap- 
sule ovoid-conical, an inch long. Seeds terete, slender, with a slightly wing- 
ed raphe.— We are confident that there is but a single North American spe- 
cies of this section, upon which the H. pyramidatum of Alton must have 
been founded : we therefore adopt the oldest name. We have not seen the 
figure of Ventenat: the character "'stylis brevibus crassis," Choisy, in DC. 
is not applicable to our plant,

very numerous, as large as in the preceding species. Petals obovate-oblong. 
Styles dilated and divariate at the base : stigmas capitate. Capsule conical- 
ovate. Seeds roundish-ovate, minutely striate. — Nearly related to the pre-

minute vesicles tilled with an intensely purple coloring matter, which is so- 
luble in water. 

§ 3. Stamens very numeroxcs, more or less polyadelphous : capsule 1-cell-

smaller ones often fascicled in the axils or on short branches. Dichotomal 
flowers on very short peduncles. Sepals about the length of the mature 
capsule, strongly dotted ; the broader ones often with 3 pellucid nerves at 
the base ; the others lanceolate. Petals obovate-cuneifonxij but very inequi- 
lateral or falcate. Valves of the capsule not in the "least introflexed; but 
with a salient ridge opposite the thick and cord-like placentse, giving the cap- 
sule, and particularly the ovary, a somewhat triquetrous appearance. Seeds 
oval, in several rows.

minute appressed leaves; branches slender and wiry, at first diverging, at 
length nearly erect. Leaves 1-2 lines long, resembling stipules. Flowers 
very minute. Petals oblong-hnear, longer than the calyx. Styles spreading: 
stigmas capitate. Capsule dark purple, very acute. Seeds extremely minute 
oblong, yellowish ; inner integument thick and slightly fleshy.— This plant is 
without doubt a genuine Hypericum, although it is excluded from the genus 
and from the order Hypericacese by most botanists. The inner integument 
is mostly thicker than usual, in this and the following species, so that it has 
been mistaken by Gsertner and others for albumen.

166 HYPERICACEiE. HypEaicDJii 

J Species which have 7iot fallen under our observation. 

* Shrubby. 

26. H. elatum (Ait.) : trigynous; sepals lanceolate-ovate, acute ; stamens 
loncrer than the corolla ; stem shrubby ; leaves ovate-oblong. Ait. Kew. {ed. 
l.)\ p. 104. 

The H. elatum figured by Jussieu (in ann. mus. 3. i. 17.), is probably dif- 
ferent from Alton's plant, and is doubtless not a native of North America. 

27. H.Jastigiatum (EH.) : branches somewhat compressed; leaves nar- 
rowly lanceolate, very acute ; corymbs terminal, many-flowered, fastigiate; 
styles united. Ell. sk. 2. p. 31, not of H. B. <^ K. 

Pine barrens of Scriven county, Georgia. May-July. — Shrub 3 feet high. 
Leaves about 3 inches long, tapering yet connate at the base. Corymbs 
with solitary flowers nearly sessile in the lower divisions. Styles not sepa- 
rating as the pod matures. Elliott. — We have no specimens which agree 
with this description. 

♦ * Herbaceous. 

28. H. Icevioratum (Ait.) : trigynous; leaves ovate, somewhat clasping; se- 
pah ovate, acute; panicle trichotomous, the intermediate flower sessile. Ait. 
Kew. {ed. 1.) 3. p. 106. 

Referred by Willdenow and most succeeding authors to H. nudiflorum; 
but the dichotomal flowers in that species are not sessile. Perhaps H. angu- 
losum, or H. eliipticum. 

29. H. sessilijlorwn (Spreng.): trigynous; branches terete ; leaves half- 
clasping, cordate-oblong, veinless, punctate ; corymb terminal, with the flow- 
ers nearly sessile ; sepals oblong, acute, foliaceous, much longer than the co- 
rolla; styles united. Spreng. syst. 3. p. 346. 

Described from a specimen in Willdenow's herbarium. Probably H. myr- 
tifolium. 

30. H. virgatum (Lam.) : stem straight, 4-angled ; leaves ovate-lanceo- 
late slightly clasping, punctate with black dots, re volute on the margins ; pa- 
nicle dichotomous, few-flowered ; sepals lanceolate; styles 2-3; stigmas capi- 
tate. DC— Lam. diet. 4. p. 158 ; DC. prodr. 1. p. 547. 

■■/ 31. H. cistifolium (Lam.): stem angular; leaves ovate-oblong, rather 
acute somewhat clasping, punctate with black dots beneath, revolute on the 
maro-ins ; flowers in dichotomous corymbs ; sepals ovate ; styles united. DC. 
I. c.—Lam. diet. 4. p. 158. 

32. H. hedyotifolium (Foir.): stem straight, 4-angled ; leaves sessile, de- 
cussate, lanceolate, rather acute, appressed, not pellucid-punctate, but with 
black dots beneath ; sepals linear-lanceolate, with black dots ; styles 3-4 ; 
stigmas capitate. DC. I. c.—Poir. diet. 7. p. 700. 

Doubtless H. angulosum. 

33. H. triplinerve (Vent.): stem herbaceous, 3-angled, decumbent at the 
base ; leaves Unear, much spreading, obtuse, with revolute margins ; sepals 
ovate, acute ; petals unequal. DC— Vent. hort. Cels. t. 58 ; DC prodr. 1.

On the banks of the Ohio, Michaux, ex lent.— We have not seen the 
fio-ure and original description of this species ; but the character given by 
Pursh which is apparently taken from Ventenat, includes several important 
partic'j'a-'^ not mentioned by Choisy ; whose elaboration of the species of 
Hypericum in De Candolle's Prodromus is far froiB satisfactory. The stem 
is said by Pursh to be erect, the leaves triplinerved, the flowers as large as in 
H. perforatum, and the sepals and petals glandulose-serrate. 



Elodea. HYPERICACEiE. 167

est about 6 lines long ; the lower ones much smaller. Dichotomal flowers pe- 
duncled. Ckam. <f .Sc/i/ec'i^.— Allied to H. humifusum, according to the 
authors cited ; and apparently also to H. mutiium. 

35. //. aciitifotmm. (Ell.) : stem herbaceous?, branching, glabrous ; leaves 
narrowly lanceolate, acute; panicle many-flowered; capsules scarcely longer 
than the calyx. Ell. sk. 2. p. 26. 

Milledgeville, Georgia, Dr. fiVii/Zrin.— Resembles most the H . Canadense, 
but larger in every rc-pecl: it differs also in its acute leaves, proportionally 
short capsule, and much more compact panicle. Elliott.

feet high, often of a puri)lish hue. Stem nearly terete, branching. Leaves 
oblong, 1-2 inches or a little more in length, somewhat glaucous underneath. 
Axillary cymes mostly about 3-flowered ; the terminal one often compouiid. 
Petals obovate-oblong, nearly twice the length of the calyx, marked with 
reddish veins. Stamens rarely 12 or more, always triadelphous ; the fila- 
ments seldom united more than one-third of their length, shorter than the pe- 
tals. Glands ovate, orange, secreting a copious sweetish fluid. Capsule ob- 
scurely triangular, nearly twice the length of the calyx when mature, rather 
acute. Seeds oblong, very numerous.

campulitropous. Embryo more or less curved around the outside of 
mealy albumen. — Herbaceous or rarely suffrutescent branching plants, 
with opposite or fascicled (rarely alternate) entire mostly sessile

§ 1. Annual: sepals similar, dilated and fornicate at the apex within, 
produced posteriorly into a divaricate horn or awn: Jlowers cymose. 
— (Chjetonychia, DC. ?) 

1. P. Drummondii: minutely pubescent; stem erect, branching above 
into numerous cymes ; leaves (of the branches) linear-oblong, short, the 
uppermost mucronate ; calyx turbinate at the base, with a ring of hooked 
hairs; sepals broadly scarious and dilated above, the back produced into a 
short somewhat recurved horn ; sterile setfE very minute. 

Texas, Drummond I (2nd Coll. no. 93)— Stem stout, 10 inches high. 
Leaves of the stem wanting in the specimen ; of the branches rigid, hispidly 
canescent, i an inch long, attenuate at the base ; the uppermost smaller and 
bract-like. Stipules ovate, with a slender acumination, shorter than the 
leaves. Ultimate bracts (bracts? and stipules of bracts) scarious, ciliate, 
shorter than the flower. Sepals reddish-brown, the scarious margins and 
horn white. Stamens much shorter than the sepals. Sterile seta? perhaps 
often Avanting. Style very short.— This species manifestly belongs to the 
section Chsetonychia, DC. 
_,, 2. P. setae ea : nearly glabrous : stem erect, branching into the many times 
' dichotomous diffuse cyme ; leaves subulate-setaceous, erect ; bracts similar, 
cuspidate ; sepals hairy at the base, minutely scarious on the margin, the 
apex arched within, the back produced into a slender diverging awn ; sterile 
setse as long as the filaments. 

Texas, Drummond ! (3rd Coll. no. 33.)— Slender, 3-5 inches high. Leaves 
about the length of the internodes. Stipules shorter, lanceolate, attenuate 
into a long point. Sepals (and also peduncles and leaves) brownish, oblong- 
linear : awn straight, whitish, someAvhat shorter than the sepals. Styles the 
length of the utricle, distinct more than half-way down. 

§ 2. Perennial : sepals similar, cuspidate or axvned, the apex some- 
what cucullate or concave within, but not dilated: flowers in dichoto- 
mous cymes or axillary glomerules, or sometimes nearly solitary.— 

EUNYCHIA, DC. 

The species with the flowers enveloped by scarious bracts may perhaps forrn a 
separate section (Argyronychia) : P. dichotoma (Ploltzia, Am.) cannot be distin- 
guished as a genus. 

,> 3. P. sessilifiora (Nutt.): very densely csespitose, much branched and

half an inch long, slightly 2-sulcate, about the length of the internodes. Sti- 
pules shorter than the leaves, ovate-lanceolate, acuminate, or setose ; the 
point much shorter than in P. dichotoma ; the flowers smaller, fewer, and 
more crowded ; the cusp stouter and confluent with the arched inner por- 
tion. Calyx obpyramidal at the base. Style 2-cleft \ of its length. The

more in length (those of the flowering stems larger than the internodes ; of 
the barren stems imbricated), erect, 2-sulcate beneath, about i a line wide. 
Stipules lanceolate, piliferous ; the adjacent ones more or less united. Se- 
gals yellowish, the base lined with a Avhitish disk. Style filiform, nearly as 
ougas the sepals, cleft usually about i its length.— Separated from Parony- 
chia by Arnott, who however did not observe the 2-cleft style and the mi- 
nute sterile sets, which indeed are not easily detected in dried specimens. 
P. Jamesii connects it with other species of the genus. Nuttall's syno- 
nym, " Illecebrum dichotomum, Tf7//c/." is perhaps a mistake, as there is no 
such species in WiUdenow's Species Plantarum.

sists of the ordinary central 1-floAvered ebracteolate peduncle, and two lateral 
few-flowered peduncles evolved somewhat later ; and the stem is continued 
by a fourth or adventitious branch, which throwing the inflorescence on one

Nuttall has brought specimens, also in fruit, from St. Barbara, California, 
which agree perfectly with Hooker's figure, except that the upper leaves and 
sepals are very sparingly ciliate with minute processes of the cuticle rather 
than hairs, which are moreover not glandular. We have the same plant from 
Douglas's Californian collection in flower, with the margins of the leaves 
almost wholly naked. The petals are rose-color or purple, rather longer than 
the sepals ; the stamens 6-8, and the seeds numerous.

In the Rocky Mountains, Lewis ex Pur.'sh ; Drummond ex Hook. — We 
quote the character of this species from Hooker ; whose specimens, smaller 
than the plant figured by Pursh and with broader slightly notched petals, are 
very similar, as Hooker himself remarks, to the preceding species, differing 
indeed chiefly in the sessile cauline leaves. We have the same plant or a 
form intermediate between it and C. Caroliniana, from Dr. Pitcher, collected 
probably in Arkansas. The following is the character given by Pursh : " C. 
foliis lanceolatis : cauUnis ovatis sessilibus, racemeo solitario elongato, calycis 
folioli? brevibus obtusissimis, petalis cuneatis bifidis, radice tuberosa. — Flow- 
ers white, nearly the size of C. Virginica.^ without veins." — We cannot help 
suspecting that Pursh's figure is made up of two species, and that the flow- 
ers at least belong to C. alsinoides.

Te.xas, Dnimmond\'—Thv specimens of no. 47 I 37 ?) in Drummond's 
2nd collection agree minutely Avith the very detailed descriptions of L. selagi- 
noides by St. Hilaire & Schiede, except that in our plant the stems are near- 
ly erect, sparingly branched, and (as well as the midrib and margins of the 
leaves) minutely 'and sparsely scabrous-hispid ; the margin of the rigid stpals 
is broadly scarious, slightly c'iliate-serrulate above ; the filaments are not re- 
markably broad ; and the styles, which are twice the length of the ovary, are 
united for more than half their length, which is very remarkable in this family. 
Still, as the descriptions referred to arc not sufficiently explicit upon some of 
these points, it is not improbable that our plant belongs this species.

Order XXX. LIMNANTHACE^. R. Br. 

Sepals 3-5, united at the base, persistent, with a valvate aestivation. 
Petals 3-5, marcescent. Stamens twice the number of the petals, and 
inserted with them upon a thin somewhat perigynous disk : filaments 
distinct, those opposite the sepals having a small process or gland at 
the base on the outside, those opposite the petals sometimes shortest : 
anthers roundish, introrse. Ovary consisting of 2-5 distinct carpels, 
opposite the sepals ; the styles united into one nearly to the top : stig- 
mas simple. Achenia rather fleshy? the cavity filled by the solitary 
seed. Seed erect, anatropous, without albumen. Embryo with very 
large amygdaloid cotyledons ; radicle very short, included. — Annual 
glabrous herbs (exclusively North American), with more or less of the 
acrid taste of Tropaeolum, growing in swampy places. Leaves alter- 
nate, exstipulate, pinnately divided. Flowers axillary, solitary : pedun- 
cles somewhat dilated at the apex. 

The ovaries in this order have a gynobasic structure ; that is, are more or less 
distinct, with the styles united by means of a more or less manifest central axis, 
which is a prolongation of the flattened torus on wliich the ovaries rest. The order 
is evidently more nearly allied to Tropaeolum than to any other known plants.

the genus Pitavia (or Galvezia) as defined by Ad. Jussieu, in his Mc7n. sur

slightly compressed, agreeably acid. This plant varies greatly in the degree 
of pubescence of the leaves. R. suaveolens of Alton differs merely in the 
leaves being almost glabrous, so that we have no hesitation in referring it to 
the present species.

"On bushy plains, near St. Barbara, California. — A low spreading tree or 
large shrub, much branched and very leafy, exhaling to a considerable dis- 
tance an aromatic odor, something like that of the Bitter Almond, (whence 
the name, from /laXa vakU & oufioq, odor.) Leaves very pale, pinnately 
but not prominently veined, about 2 inches Ion?, often slightly emarginate at 
both ends: petioles more than i an inch in length. Flowers very small and 
numerous. Calyx fleshy ; segments obtuse. Petals oblong, a little longer

genu5, belongs the LUthi of Fuillee, or Laurus caustica of Molina, the 
Rhus ? caustica, i/ooA:. if- Am. bot. Beechey^svoy. p. 15. t. 7, a species which 
differs from ours in its larger decandrous flowers, and much shorter petioles; 
we are not informed whether the fruit of that species yields an aromatic 
odor. Mauria, //. B. ^ K. also differs but little from the plants of this curious 
section ; and both possess the venomous properties of Toxicodendron." Nutt. 
— The R. ? caustica, Hook. ^ Arn. is described as dioecious; but the accom- 
panying plate represents, among others, one apparently perfect flower.

ral series, persistent, somewhat similar to the rather imbricated bracteoles at 
the base. Petals 5, oblong, slightly unguiculate, of the same texture as the 
sepals, pubescent within near the base, inserted under the margin of the disk. 
Stamens 5-7. Style short: stigma minute, 3-lobed. Fruit a dry flattened 
drupe ; the pulp very acid and astringent : nut compressed, bony, 1-celled. 
Seed solitary, suspended from a funiculus rising from the base of the cell. — 
Low and much branched submaritime trees. Leaves simple, alternate, thick 
and coriaceous, persistent. Flowers polygamous, sessile, in terminal con- 
tracted panicles. Bark exuding small quantities of a very astringent gum- 
resin." Nutt. 

1. S. integrifolia (Nutt. ! mss.) : " leaves oval, very obtuse at both ends, 
entire, on short petioles. 

" On the margins of cliffs, &c. near the sea, around St. Diego & St. Bar- 
bara ; common. — An unsightly tree, about the thickness of a man's arm, 
branching widely and forming almost impervious thickets, glabrous ; the 
young leaves and branches minuteljr pubescent. Leaves an inch or more 
long, three times the length of the petioles, rather prominently veined beneath. 
Flowers in few-flowered sessile clusters upon the short branches of the pani- 
cle. Sepals and petals reddish. Drupes the size of a pea, hirsute. — Fruit 
similar in most respects to that of Rhus § Sumac ; inflorescence somewhat 
approaching that of Lobadium ; differing from both, particularly in the gra- 
dual transition from bracts to petals. To this genus apparently belongs Rhus 
atra, Forst., of New Caledonia, of which I hav&seen an original specimen, 
but with:)Ut the flowers: the leaves are 3-4 inches long, very thick and rigid, 
attenuated into short petioles, with very prominent anastomozing pinnate 
yeins. Rhus mollis, H. B. ^ /f., also evidently belongs to the genus." Nutt. 

2. S. serrata (Nutt. ! mss.) : " leaves oval or ovate, on very short petioles, 
sharply repand-serrate. 

" With the preceding, from which it differs merely in its leaves, which 
when young are sharply serrate with small mucronate teeth ; the older leaves 
are obscurely repand-serrate." Nutt.

in sestivation, inserted on the outside of a conspicuous hypogynous 
disk. Stamens equal in number to, or some multiple of, the petals, in- 
serted upon the disk in a single series : filaments flattened below, 
sometimes distinct, sometimes monadelphous or polyadelphous : an- 
thers innate or attached near the base, versatile, the connectivum 
articulated with the filament. Ovary several-celled, composed of 
several united carpels : style 1, cylindrical : stigma somewhat lobed, 
thickish. Fruit (an orange) consisting of several (or by abortion of

Mr. Ware are very imperfect, and exhibit neither the flowers nor fruit. We 
possess similar specimens of the same plant collected in Southern Florida by 
Dr. Hassler and communicated to us by the Columbian Horticultural So- 
ciety. The plant is probably not indigenous to Florida. Wight & Arnott 
unite L. crenulata with L. acidissima. 



Citrus. — Wm. Bartram (in his Travels through North and Sotdh Carolina, 
Georgia, and Florida, 1791,) makes frequent mention of extensive groves of wild 
Orangje trees in East Florida, as far north as lat 28'^. In a notice of the town of 
New Smyrna he observes: " I was there about 10 years ago, wiien the surveyor run 
the lines of the colony, where there was neither habitation nor cleared field. It was 
then a famous Orange grove, the upper or south promontory of a ridge nearly half a 
mile wide, and stretching north about 40 miles, &c. &c. All this was one entire 
Orange grove, with Live-Oaks, Magnolias, Palms, Red Bays, and others." Bartr. 
I. c. note on p. 244. See also p. 253, &c. These groves seem to be well-known in 
Florida at the present day, and are generally supposed to be indigenous. According 
to the late Mr. Croom " they are rarely found north of lat. 29^ 30', although there 
is a small grove near the Alligator Pond, which is somewhat nnrth of lat. oO°," 
Croom, mss. The fruit is known by the name of Bitter-sweet Orange.

Order XXXVIII. MALVACEAE. Juss. (in part) ; DC. 

Sepals 5 (rarely 3 or 4), more or less united at the ba.se, often hav- 
ing an external calyx or involucel : sestivation valvate. Petals hypo- 
gynous, equal in number to the sepals, with a twisted aestivation.

tals, monadelphous : anthers 1-celled, reniform, bursting transversely : 
pollen hispid. Ovary formed by the union of several carpels round a 
common axis, either distinct or cohering : styles as many as the car- 
pels, united or distinct : stigmas as many or twice as many as the car- 
pels. Fruit capsular, or rarely baccate: carpels 1- or many-seeded, 
sometimes closely united, sometimes separate or separable ; the dehis- 
cence loculicidal or septicidal. Seeds campulitropous or heterotropous, 
with little or no albumen. Embryo curved : cotyledons foliaceous, 
twisted and doubled up. — Herbs or shrubs. Leaves alternate, stipu- 
late, mostly palmately veined : pubescence mostly stellate.

PinmsyWrnua, Muhlenberg ; Virginia? Elliotl. — (J) Stem 12-18 indies 
high, sparingly branched, clothed with while hairs toward the summit. 
Leaves ovale, toothed, very obtuse at the base, nearly glabrous above, hairy 
on the veins beneath : petioles an inch long. Flowers axillary, solitary : pe- 
duncles 2-3 lines long. Bracteoles setaceous. Petals twice as long as the 
calyx, yellow. Carpels hispid, collected into a depressed globular head, 
EUioll. — .\ultall, who saw the plant here described in Elliott's herbarium, 
considered it the Malope Matacoides. According to EUiott it is the Malva 
Americana of Muhlenberg, but not of Willdcnow. We have not the means 
of determining the genus of this plant, but believe it to be a species of Malva.

monly two or more together from the axils of the upper leaves, 3-8 inches long. 
Flowers as large as in Papaver Rha?as. Bracteoles spatulate-lanceolate. Ca- 
lyx divided below the middle; segments ovate-lanceolate. Petals bright pur- 
plish-red, truncate and eroselv crenate at the extremity. Carpels 15-20, dis- 
posed in a depressed circle, glabrous, reticulated andlacunoseon the back and 
sides. — The plant of Cavanilles was from Louisiana, for which subsequent au- 
thors in copying his description have written '"Lusitania." The mistake 
was first detected by Dr. Graham.

the Rocky Mountains, near the sources of the Columbia." We have not 
seen the flowers, but there is little doubt that the inflorescence is the same as 
in A. saccharinum.

Carolina, Michaux. Flowers pale green, sometimes all staminate, some- 
times with perfect flowers intermixed. Mich.v. — This species, of which it is 
remarkable that the younger Michaux makes no mention whatever, either in 
his general observations or catalogue of North American Maples, has been 
identified by no succeeding botanist except Pursh, who adds " In deep pine 
and cedar swamps. New- Jersey to Carolina; April-May. A small tree: 
leaves small." But Pursh's plant seems to be our /?. of A. rubrum ; at least 
specimens of A. rubrum, without fruit or flowers, exist in herb. Barton label- 
led, apparently by Pursh, A. barbatum. The flowers and inflorescence of 
this plant, however, do not at aU agree with Michaux's character. We sus- 
pect, indeed, that the description of A. barbatum, Michx. was draAvn up, at 
least as to the flowers and fruit, from specimens of A. saccharinum ; the only 
species, so far as we are aware, which has the sepals bearded inside.

times a small tree. Leaflets often somewhat doubly serrate, all except the 
lateral ones usually attenuate at the base, at length petiolulate, smooth and a 
little shining above. Branches of the thyrsus about 3-flowered : pedicels 
slender. Flowers large. Calyx purplish', nearly glabrous, tubular-funnel- 
shaped. Upper petals longest ;' the claw about thrice the length of the small 
spatulate limb: hmb of the lateral petals roundish, about the length of the 
claw, somewhat convolute. Stamens 6-8 : filaments filiform, nearly straight, 
hairy beloAv, as also the claws of the petals, sometimes all a little shorter than 
the lateral petals ; but a portion usually a little exceeding the upper petals.-— 
Our p. discolor, of which we have specimens both from Georgia and Louisi- 
ana is not improbably the M. discolor of Pursh. The inflorescence resem- 
bles that of JE,. flava; but the flowers (apparently pale dull red, or purple) 
are wholly those of M. Pavia.— According to Elliott, the bruised branches 
or powdered seeds of this species are sometimes employed to stupify fish : 
when the water of small ponds is impregnated, the fish rise to the surface al- 
most lifeless, and may be taken with the hand. The root, according to the 
same authority, is used as a substitute for soap in washing woollen clothes.—

2. UNGNODIA. Endl. atakta botanica, p. .. t. . 

We have not yet received the above-cited work of Endlicher, in the fifth fiisciculus 
of which (according to Sir Wm. Hooker) this very remarkable genus is figured 
and described. The plant was collected by the late Mr. Drummond in Texas, and 
specimens were distributed witii his first Texan collection. It forms a large tree; 
the leaves are alternate, and pinnately 5-foliolate : the flowers are small, in few-flow- 
ered racemes, which appear to be axillary or clustered along the branches : the se- 
pals are nearly distinct : petals 5 (rarely 6), similar, spreading, witli an obovate 
slightly crenulate lamina, raised on a short and very thick woolly claw, which bears 
at its summit a curious fimbriate crest: stamens 8-10, declined and much exserted, 
a portion of them apparently somewliat coherent with a small unilateral appendage 
orprojectiou of the torus, or with the base of the (effete 1) ovary. Fruit not seen. 

Order XLV. SAPINDACEiE. Jiiss. 

Flowers usually polygamous. Sepals 4-5, distinct or nearly so, im- 
bricated in aestivation. Petals as many as the sepals and alternate 
with them, or fewer by the abortion of one (sometimes entirely wanting), 
inserted outside the hypogynous disk (or row of glands) which occupies 
the bottom of the calyx ; the inside either naked or hairy, glandular 
or furnished with a petaloid scale. Stamens 8 or 10, rarely fewer or 
more numerous, inserted either on the disk, or between the glands and 



254 SAPINDACE.E. Sapfndus. 

the ovary : filaments distinct or very slightly united at the base : an- 
thers introrse (the pistil of tlic staminate flowers either rudimentary 
or entirely wanting). Ovary comppsed of 3 (rarely 2-5) united car- 
pels : styles partly or completely united : ovules solitary in each cell, 
erect or ascending ; sometimes 2, the upper one ascending, the lower 
suspended ; rarely 3 or more. Fruit 2-3-ceiled, capsular, vesicular, 
or samaroid, or frequently fleshy and indehiscent. Seeds 1-3 in each 
cell, usually arilled, without albumen. Embryo rarely straight ; the 
cotyledons usually incumbent on the radicle, or spirally convolute, some- 
times combined into a thick mass. — Trees, or tendril-bearing shrubs 
or herbs. Leaves alternate, usually compound and exstipulate, often 
marked with pellucid lines or dots. Flowers small.

Order XLVI. CELASTRACE^. R.'Br. 

Sepals 4-5, united at the base, imbricated in aBstivation, usually 
persistent. Petals as many as the sepals and alternate with them, 
plane, inserted by a broad base under the margin of the disk : estiva- 
tion imbricated. Stamens as many as the petals and alternate with 
them, inserted on the margin or upper surface of the large flat and 
fleshy disk which covers the bottom of the calyx : anthers introrse.

256 CELASTRACE^. Staphylea. 

dill dehiscence. Seeds anatropous, 1 or few in each cell, ascending or 
erect, or by resupination suspended, often arillcd : albumen fleshy, often 
very thin or wanting. Embryo straight, usually nearly as long as the 
albumen : radicle short : cotyledons thick or foliaceous. — Slirubs, or 
rarely trees, with alternate or opposite leaves. Flowers sometimes po- 
lygamous or dioecious. 

Cyrilla, Linn, and Cliftonla, Soland. in kerb. Banks and Gcprtn. (Mylocarium, 
Willi!.) are i-eferred to this family by Lindley, we know not on wliat ground ; since 
they liavc not a flat perigynous disk; their stamens are twice the nnmber of the pe- 
tals, the latter are inserted by a narrow base ; their ovaries have a single suspended 
ovule in each cell, and the embryo is cylindrical and slender. These two genera, 
with Elliottia, J\luhl., form apparently a suborder of Ericacea3, perhaps even a 
group of equal rank with Pyrolacese, &c., (which may receive the name Cyrille^, 
from the oldest genus), distinguished from Ericacea; proper by the ovary seated upon 
a short torus, with a single suspended ovule in each cell, by the texture of tiie peri- 
carp, the flat or dilated filaments, with the cells of the anthers not separated or ap- 
pendaged either at the apex or base, and opening longitudinally ; and by the polype- 
talous corolla (the petals of Elliottia, although cohering at the base, are at length 
separable), which is hardly met with in true Ericaceae, except in Cletbra, to which 
Elliottia is somewhat related. Pickeringla, JVwW. (Cyrilla paniculata, Nutt. in Sill, 
jour. 5. p. 290) is, as the acute botanist and zoologist to whom it was dedicated first 
suspected, a species of Ardisia ; probably A. coriacea, Sicarlz, a West Indian plant.

evergreen in the Southern States. Parts of the flower mostly in threes or 
fives. Segments of the calyx very short and roundish. Petals greenish-yellow, 
tinged with purple. Capsule deep crimson when mature, slightly angled,

In shady woods, Georgia, Lyo7i ex Pursh. — Specimens of this plant which 
we have seen in the herbaria of Muhlenberg and Collins certainly appear 
different from E. Americanus; but the characters of the leaves will probably 
not be found constant, and there seems to be no other difference.

Subalpinc hills, N. W. Coast, Menzies ; and throughout the Rocky Moun- 
tains, Lewis! Douglas, Nuttall I—^'Thi; wliole plant scarcely 2 feet high, 
densely branched, covering the steep sides of bushy hills, very leafy. Leaves 
varying from roundish-oval to linear-oblong, half an inch to above an inch in 
length, coriaceous, glabrous, shining above, sometimes Avith numerous, some- 
times with small and sparse or obsolete serratures ; the taste slightly bitter 
and astrinijent, very similar to that of black tea, or to that of Ilex vomiloria, 
for which it was mistaken by its discoverer, the indefatigable Menzies. Pe- 
duncle very short, l-3-tlo\vered : pedicels 2-bracteolate, slender. Flowers 
monoscious. The whole aspect of the plant is that of Phillyrea media; while 
its true affinity is with Celastrus, from which it differs much in habit: a lacerat- 
ed membrane takes the place ol the fleshy aril. A»i^." — Pursh described this 
plant very badly. Hooker has given an excellent description and figure, 
which leaves nothing to be desired except as to the fruit and seeds (which 
have now for the first time been obtained by Nuttall) ; he suspects it should 
be removed from Myginda. Arnott observes (in prodr. hid. Or. I. p. 155.) 
that " M. ilicifolia, myrsinoides, and myrtifolia, having a bilocular ovary with 
two erectovules in each cell, form a distinct genus, as has already been remark- 
ed by Kunth" ; but most probably our plant is not a congener of the West In- 
dian M. ilicifolia. The flowers are said by Nuttall to be monoecious ; but 
this is at least not uniformly the case in our specimens : and perfect flowers 
are also represented in the detailed figure of this plant given by Sir Wm. 
Hooker.

base of the calyx unusually large. Seeds even on both sides, black, polished. 
— The whole plant (like several succeeding species) exhales a balsamic odor, 
and the mature fruit is covered with a bitter varnish. Hooker describes the 
branches as ferrugineous, which is not the case in our specimens : they are 
so, however, in the C. macrocarpus, which, judging from our specimen, we 
were certainly inclined to unite with the present species ; but Mr. Nuttall 
assures us that it is perfectly distinct.

inch long, and 4-5 lines wide, similar to the preceding in texture, venation, 
&c. Flowers white. Fruit the size of a large pea.'* Null. — Very near C.

merous umbel-like fascicles ; ovary with three protuberances at the summit. 

California, Douglas ! — Leaves scarcely half an inch long, strongly and 
remotely feather-veined, pitted beneath, irregularly and obtusely toothed. 
Peduncles an inch or more in length. Flowers crowded, white. 

19. C. papillosus : branches tomentose ; leaves narrowly oblong, much 
crowded, fascicled in the axils, densely and softly tomentose beneath, gland- 
ularly denticulate on the margin ; peduncles aggregated ; clusters somewhat 
capitate ; ovary triangular, the angles projecting at the summit. 

California, Douglas! — Branches terete. Leaves 1-1 i inch long (those 
fascicled in the axils smaller), fringed on the margin with numerous capitate

Sandy or stony shores, from Labrador to New- York! and from Kotzebue's 
Sound! to Oregon! and California: also around the shores of the Great 
Lakes ! and along the rivers, &c. to the shores of the Arctic Sea (Richard- 
son). May-July. — The whole plant has a somewhat glaucous aspect, and 
much the habit of a Pea. The leaflets (often scattered) are commonly from 
li to 2 inches in length, and |-1 inch wide, with reticulated veins ; in shady 
situations the stem is more slender, less leafy, and the leaflets rather smaller. 
Stipules usually toothed below, cordate-hastate, the lower angle or lobe acute, 
often more or less inequilateral. Peduncles 6-10-flowered. Flowers large 
and showy, purple; the wings and keel paler. Lower segment of the calyx 
linear, a little narrower, and slightly exceeding the lateral ones. The speci- 
mens from Arctic America are smaller and fewer-flowered. — Our specimen 
of L. pisiformis from Altaic Siberia, communicated by Prof. Fischer, dif- 
fers from our various forms of the plant above described in having a narrow- 
ly winged stem, much larger and semisagittate stipules, and somewhat ovate- 
oblong leaflets. We perceive no other diff"erence of any importance ; but, as 
these may be expected to prove nearly constant, we have thought it best to 
retain the specific name of Bigelow for the present, since our plant is doubt- 
less the same as the Pisum maritimum of the North of Europe. 

3. L. polyphijlhis (Natt.l mss.): "glabrous; stem nearly erect; angled, 
leaflets 5-8 pairs, oval-oblong, obtusish, the tendrils very short ; stipules as 
large as the leaflets, semicordate, angularly crenate at the base, sometimes 
acuminate; peduncles 7-10-flowered ; shorter than the leaves ; segments of 
the calyx hairy on the margin, the two upper ones triangular and much 
shorter than the lanceolate lateral ones, the inferior one subulate-setaceous, 
rather longest ; corolla purple ; legume smooth, acuminated, long and flat. 

" /?. angles of the stem acute ; stipules broadly semisagittate. 

" Forests of the Oregon to the sea ; in shady places.— Stem about 2 feet 
high. Leaflets 1^ inch long, and half an inch or more wide. Flowers ra- 
ther large. — Considerably allied to L. pulchellus of Altai, but with more flow- 
ers on the peduncle." Niitt. — This plant is probably included by Hooker 
among the "more lax and flaccid forms of L. pisiformis apparently inhabit- 
ing woody districts ;" and we should incline to take the same view of it ; 
but the setaceous inferior segment of the calyx, and the rather shorter supe- 
rior teeth wiU perhaps prove a constant distinction.

approach to L. palustris that we arc unable to point out any certain and con- 
stant mark of distinction. The leaflets are ordinarily an mch and a half in 
length and about half an inch wide, veiny, and rather rigid. The stipules 
are'extremely variable in size, being sometimes half the size of the leaflets, 
but often (especially the lowermost) very smaU : their base is sometimes

lum and winars broad. Calyx very smaU. The immature pods, in the spe- 
cimen of Dr. James, are about 2 inches long, and nearly half an inch wide, 
reticulated, tapering below into a distinct stipe. The seeds, according to 
Dr. James, are as large as the Common Pea. — This species and L. polymor- 
phus are (as the genera are characterized) rather species of Orobus than of 
Lathyrus : they are clearly congeners of O. varius, O. albus, and others of the 
same section ; but on the other hand they can hardly be separated with pro- 
priety from L. linearis, Nittt.. which has tendrils and more the habit of the

♦ From a remark in Mr. Bentliam's late memoir, De Les^uminosnrnm generihus, 
p. 49, we perceive that E. Meyer considers the orif^inal Rhynchosia of Loureiro to 
be different from the Rhvnchosia of De CandoUe ; and he has therefore applied the 
name of Copisma to the latter. But if this view be correct, the name Arcyphyllum 
of Elliott has the priority.

regarded by Michaux. The var. monophylla sometimes bears trifoliolate 
leaves, and late in the season produces long axillary branches, which are 
sometimes twining. The racemes are extremely variable in length; but we

longest ; the upper one bifid at the apex. Corolla deciduous : vexillum (gla- 
brous) obovate or nearly orbicular, without callosities, the margins of the 
short spurs and of the claw folded in : wings smaller than the keel-petals, 
narrowly oblong, somewhat falcate, with a subulate tooth at the base nearly 
the length of claw : the keel conspicuous, rounded, a little falcate, rather shorter 
than the veKillum. Stamens diadelphous ; the free filament articulated at 
the base. Ovary semi-oval, compressed, hairy, 2-ovuled : style filiform, the 
lower portion hairy, the upper half indurated : stigma small, subcapitate, 
glabrous. Legume oblong, tapering at the base, sessile, several times longer 
than the calyx, compressed, 1-2-seeded. Seeds roundish, somewhat carun- 
culate. — Erect and rigid perennial herbs, with numerous slender and simple 
branches. Leaves small, pinnately trifoliolate, on very short petioles : leaflets 
elliptical or oval, the lower surface copiously dotted with resinous atoms. 
Stipules minute, setaceous, deciduous. Flowers solitary or nearly so in the 
axils of the upper leaves, rather large, "yellow, the vexillum marked with 
numerous red lines" {Chapman, in lilt.), on short pedicels. 

The genus Pitcheria is very nearly allied to Rhyncbosia, rather than to Galactia, 
as will be seen from the detailed cliaracter given above. Indeed, supposing that 
genus to comprise the subgenera indicated by Arnolt, we find it nearly impossible 
to distinguish Pitcheria by any absolute character. Our plant should also be com- 
pared with several species of De Candolle's section (or genus) Eviosema, from 
Mexico and Central America, with which it appears to agree in habit, &c. The 
genus is dedicated to Dr. Z. Pitcher, late of the United States Army, whose name 
so frequently appears as a contributor on the pages of this work.

In dry soil, Alabama, Dr. Gates ! Middle Florida, Dr. Chapman ! 
]V[ay._^Stem about 3 feet high, virgately branched ; the branches angled, 
and (as well as the calyx and veins of the leaves) minutely pubescent. 
Leaves very numerous, sprinkled beneath with rather conspicuous yellow 
dots : petioles 4-5 lines long: leaflets h-'x of an inch in length (in p. smaller), 
usually rather obovate-oval, glabrous and someAvhat reticulately veined above ; 
the terininal one a little distant from the others ; the lateral ones smaller, 
almost sessile. Flowers solitary or in pairs, on pedicels rather shorter than 
lire calyx, rising from the axils of the leaves, or in a short 2-3-flowered ra- 
ceme. Flowers 5-6 lines long: vexillum partly folded round the other petals : 
keel-petals slightly connected, very broad. Mature legumes nearly an inch 
long, and \ of an inch wide, pointed with the base of the style, straight 
Seeds mottled.— -The specimens of our var. /?., which perhaps belong to a 
distinct species, were sent from Alabama by Dr. Gates, and are not very 
complete. The leaflets (of the rameal leaves) are only 3 or 4 lines long, and 
the petioles being short in proportion, the leaves appear to be nearly sessile. — 
The flowers are stated by Nuttall to be red, and they appear reddish in dried 
apecimens. 

Subtribe 3. Glycineje, Benth.— Ovary with several ovules. Inflores- 
cence racemose, with the pedicels often more or less aggregated on small 
alternate knobs. Bracteoles very small, often deciduous. Vexillum usually 
biappendiculate. Style not indurated. Cotyledons flat, foliaceous in germi- 
nation. — Flowers small.

G. pallida. G. mollis, Pursh, probably includes two species.

Flowers of two kiuds ; those of the upper many-flowered racemes perfect 
and petaliferous, but seldom maturing fruit ; those near the base of the stem 
or on prostrate branches imperfect, but usually fertile. Perkect Fl. Calyx 
tubular-campauulate, about equally 4-toothed (the two upper teeth being

very long claws, the lamina oblong, that of the wing-petals with a very small 
callous or saccate spur at the base. Stamens diadelphous. Ovary 4-ovuled

brownish hairs. Leaves pinnately trifoliolate : leaflets rhombic-ovate, mi- 
nutely stipeUate. Stipules striate, similar to the bracts. Racemes of the 
petaliferous flowers solitary or in pairs, often somewhat compound, with the 
flowers clustered or in pairs from the axils of the bracts : the bracts per- 
sistent, orbicular, partly clasping, appressed, alternate (but each formed by 
the union of the pair). Inflorescence of the imperfect or radical flowers 
similar, but with the filiform peduncles few-flowered, and the bracts distinct 

This genus is manifestly correctly referred by Bentham to his subtribe Clitorieae ; 
although thepeculiar inflorescence which appears to exist in the whole group is some- 
what masked by the apparently alternate bracts (a deviation, however, wliicii is evi- 
dently caused by the union of each pair of bracts into one) ; but in A. moiuiica the 
vexillum is sliglitly appendiculate at the base, with the margins of the auricles fold 
ed in, and the upper portion of the style is somewhat indurated, as in Euphaseoleae.

Calyx without bracteoles, about equally 5-toothed or 5-cleft. Vexillum 
large, roundish, spreading or reflexed, usually silky or pubescent on the out- 
side: keel obtuse, cohering with the wings. Stamens monadelphous or 
sometimes diadelphous ; the tenth filament sometimes half united with the 
others. Style filiform, bearded longitudinafly, or glabrous : stigma terminal. 
Legume commonly sessile and much compressed, linear, many-seeded ; 
valves usually flat. Seeds compressed.— Shrubby or herbaceous plants, 
erect or procumbent, silky-villous. Leaves unequally pinnate (rarely reduced 
to a single leaflet). Stipules free from the petiole, lanceolate or subulate,

low tinged with purple: keel-petals very broad. Legumes 2 inches long, 
somewhat falcate, villous. — Mr. Nuttall remarks that the wings are calcaiate 
at the base as in Indigofera ; but we do not observe this.— Our Arkansan 
specimen of Avhat is doubtless T. holosericea, Nutt. has a somewhat diiferent 
aspect, and the leaflets are mostly inclining to lanceolate; but the specimen 
from Illinois manifestly connects it with the ordinary form of T. Virginiana.
