PREFACE
This volume is designed to record and deseribe the species of native
and naturalized flowering plants known by the author to grow naturally
in the southeastern United States south of the northern boundaries of
North Carolina and Tennessee and east of the Mississippi River. The
species are grouped in genera, families, and orders, and are so arranged
and deseribed that they may be identified by means of the analytieal keys
and synopses given under each group, mainly by a study of the morphol-
ogy of the flowers and the fruits. |
The arrangement of the natural plant families is essentially that of
Engler and Prantl, Die Natiirlichen Pflanzenfamilien, although in a few
eases modifications of the sequence there adopted seemed to be desirable.
The deseriptive matter has been made very short, except in special cases.
In order to facilitate the traeing and determination of genera and species,
a drawing showing a flower and its gross morphology and a fruit, of the
first species under each genus is given. The illustrations are not made
to a seale, but the sizes of some of the parts are usually given in the de-
the rw du of those of the grasses, whieh were made by Mrs. Agnes
Chase,! and those of Carex which were made by Mr. H. Creutzberg, through
the interest of Mr. K. K. Mackenzie.
the matter of the interpretation of species and genera what has
— to the author a balanced course has been followed—traditional
“lumping” and modern "splitting" have not influenced the treatments o
the various groups. Complex genera have been divided into more natural
groups, both for convenience of study and also in order to make the gen-
era, as far as possible, correspond i in rank to the great majority of groups
of species now recognized as genera by most present-day botanists.
Species have been interpreted in the broader sense; minor variations of
species, "varieties" or “subspecies” have not been considered to any great
extent. “Subvarieties”, "forms", “subforms” have not been considered
at all.
The names adopted for species and genera in this volume are those
whieh to the best of the author's knowledge, were first applied to each,
accompanied or supported by an adequate description, and in the case of
genera by specific references, from the time (1753) when binomial desig-

POLEMONIACEAE, by Dr. E. T. Wherry; su d bin by Dr.
Pennell; PINGUICULACEAE, by Dr. J. H. Barnhart; LORANTHACEAE, by Dr.
William Trelease. The text for certain genera was prepared by the follow-
ing botanists: Iris, Vincet , Odontostephana, Scutellaria, Laciniaria,
Zinnia, Melanthera, O Cosmos, Emilia, by Mr. E. J. Alexander;
Philadelphus, by Mr. C. D. Beadle; Crataegus, by Mr. Ivar Tidestrom;

E. E. Watson; Coreopsis, by Mr. F. E. Boynton; Bidens, by Dr. Karl
M. Wiegand. The following genera were revised: Viola, Aster, by Mr.
E. J. Alexander. Assistance is preparing the text of Philotria and
of Trillium was furnished by Dr. Harold St. John and Mr. Donald C.
Peattie, respectively.
Help in many ways was given by my associates on the botanical staff
of the Garden. Among those who participated in intensive field-work of
the past two decades were Mr. Charles A. Mosier, the late Captaim, Paul A.
Matthaus, and Mr. John B. DeWinkeler. Both the galley and the page
proof have been read by Dr. Edgar T. Wherry, who also supplied the
provincial distribution- of the species, checked many of the geographic
ranges, and furnished data as to habitats and soils. The galley proof was
read in whole or in part by Mr. Kenneth K. Mackenzie, Dr. N. L. Britton,
Dr. Roland M. Harper, Mr. Edward J. Alexander, and Miss Bertha Picker-
ing, while each contributor of generic or family treatments, as indicated in
the text, read the proofs of these.

This manual supplants, in part, the Flora of the Southeastern United
States published by the author in 1903 (seeond edition 1913). at
volume reeorded and deseribed the flowering plants and pteridophyta?
known at that time to grow naturally in the southern United States east
of the one hundredth meridian of longitude. The complexity and magni-
tude of the flora in this area, resulting from its proximity to the tropies,
the intrusion of the northern highlands, and the extension of the Great
Plains and the deserts from the west, made it seem desirable to divide the
“Flora” into two parts. The result is the present volume and a proposed
volume to inelude the area west of the Mississippi River south of the same
degree of latitude and east of the western boundary of Texas. Thus
smaller volumes will result, and plants may be traced by the analytieal
keys with greater ease, since fewer genera and species are usually involved.
he geographic area concerned represents one of the cradles of bot
on the American mainland, for on the coasts of the Gulf States mi
Spanish expeditioners were necessarily, not by choice, brought into close
contact with the native vegetation. They left us printed records of the
uses made of various plants by the aborigines and by themselves for foods,
drinks, medicines, clothing, utensils, and fumitories. Their interest was
not wholly utilitarian, for some plants so impressed them, the cacti for
example, that they took them back to Europe and grew them ther
out a eentury after the discovery of America by esas living
specimens of plants from the Atlantic coast began to find their way into
European botanic gardens. Explorations by plant collectors were soon
extended into the highlands and into the Florida peninsula. Later, col-
lectors were sent over from Europe and Pa were commissioned by
European patrons of botany to explore for plan American residents
about this time began to publish the results of m studies. Today t
works on the flora are numerous.
The first American botanical pum in the northeast developed near
Philadelphia, Pennsylvania, in the middle part of the eighteenth century,
as a result of the plant-eolleeting activities of John Bartram. Here many
of the plants. of the southeast were cultivated. In thé second half of that
century the first botanieal garden in the southeast grew about the home of
Thomas Walter on the Santee River north of Charleston, South Carolina.
Walter’s association with this native flora crystallized into the first manual
of the plants of a more or less definite geographic area, under the title
Flora Caroliniana, in 1788. Interest in the native plants and in botany
inereased and reached a eulmination about the middle of the last eentury,

in the publication of Chapman’s Flora of the Southern United States, in
1860. Then, botanical activity waned in the South. Toward the end of
the last century, however, a revival took place in the southeastern states,
mainly through the activities of permanent and transient residents, of
plant collectors, and of botanists and naturalists who moved into the region
to fill professional positions.
In pioneer days with the horse and few trails, the sail-boat and un-
developed water-ways, botanical exploration was restricted to limited areas
and progressed slowly, consequently the botanical harvests were often scant.
Since the advent of the automobile, the motor-boat, and the construction
of a vast network of highways, canals, and improved waterways, largely
through virgin country, a vast territory, until recently inaccessible, has been
made to yield numerous botanical and horticultural treasures. As a con-
sequence, many additional species and not a few genera of all groups of
plants have been recorded for the area under consideration only since the
end of the last century.
The area extends over about twelve degrees of latitude. The southern
limit lies within less than a hundred miles of the Tropic of Cancer. The
northern limit is not very far north, but two mountain ranges, with a mul-
titude of peaks rising to between five and six thousand feet and several
to more than six thousand, furnish a cool climate representing a high lati-
tude through altitude. Intermediate altitudes (Piedmont and Appalachian
Plateau) supply still other elements for greater variety in the vegetation.
s compared with northeastern America there are one-third more species
in about one-fifth the area. Three main factors contribute to this con-
dition—latitude, geology, physiography.
The ancestors of our present plant-covering were subjected to both
and minor earth disturbances, elevations and depressions and re-
semen of the land-mass. Submergences also destroyed vast areas
coastwise vegetation several times. When the areas emerged from the
sea for the last time and the higher lands became more stable, the coastwise
areas were populated from both the plant refuges in the highlands and
those of continental and insular regions lying to the south. Whether these
early floras were more extensive in kinds and density of population than
those of today we shall never know. The records of several different
floras are preserved in the sedimentary rocks, but they are naturally very
incomplete. Large areas of eroded materials of the very old geological
formations, often segregated into areas of different kinds of soil, such as
sand, clay, marl, loam, in the Coastal Plain and the Piedmont, very defi-
nitely contribute to the complexity of the flora. Then, in relatively recent
geologic time, came the advance of successive great ice-sheets from the
north as far south as New Jersey and Pennsylvania, with accompanying
eold, which killed the vegetation before their immediate front, while they
INTRODUCTION xi
advanced, or drove the more distant plants southward. When the ice
receded to the north some plants at the south doubtless succumbed as the
temperature rose to a point beyond their enduranee more rapidly than
they could migrate; while others accommodated themselves to the new
conditions, and traveled back to their former, more northern latitudes.
Thus our present plant population shows the results of invasions from
the north. On the other hand, peninsular Florida, and in a lesser degree
the more northern Gulf Coast, received many elements from the West
Indies near at hand, and from northern South America, carried over a
narrow ocean area by birds, winds, and currents. The physiographic struc-
ture. of the area involved furnishes a sliding seale, either from the boreal
to the tropical or vice versa, so that any plant which gains a foothold in
the area might find conditions suitable for its growth and maintenance.
The above remarks apply mainly to the eastern part of the area; here we
find a very dense plant population, specifically and generically considered.
In the western part there are less differences in elevation, and much simpler
geologic history; here there is sparser plant-population both in density and
variety.
There are many locally peculiar minor plant areas. For example,
capes, peninsulas, coastal sand-dunes, river-deltas, river-valleys or water-
sheds, swamps, marshes, plateaus, mountain-valleys, mountain ranges, and
mountain peaks, each harboring peculiar or endemic plants.
he accompanying map shows the territory included in the South-
eastern States and the Southcentral States. The Mississippi River divides
the area into approximate halves. Both areas are shown for convenience
in tracing the geographic distribution of the plants, and to show the rela-
tion of the floras of the two areas. These are closely related at the boun-
dary line, for they both naturally merge in the ancient delta of the Mis-
sissippi River or the present Coastal Plain part of the Mississippi water-
shed.

may be inferred to be acid, except in southern Florida, where the pine-
woods cover limestone rocks and have more or less alkaline soil. Other-
wise, where no statement is made as to soil reaetion, either no data are

ied Lo very well the distributional relations of plants in our region.
n the east Gulf Coastal Plain, where the Lower Austral life-zone
should supposedly be represented, there occur many Transition and even
Canadian plants which have pushed southward, west of the Appalachian
mountains, in some past geological period and have persisted there. Again,
in the Blue Ridge, where on ascending a high mountain the theoretical
sequence shoul e Upper Austral—Transition—Canadian—Hudsonian,
one finds instead a mixture of Upper Austral and Transition plants on
the lower slopes, Canadian plants further up, but then instead of any-
thing more boreal, a mixture of plants characterizing the Upper Austral
of the Atlantic Coastal Plain mingled with many Transition shrubs and
Canadian trees at the summit. It has accordingly seemed best to refer the
plants only to the physiographie provinees in which they have been ob-
served to grow, and to leave the untangling of the o E of life-
zone relations to other writers.
The physiographic province names used have been taken, with minor
modifications, from *Physiographie Divisions of the United States.”* The
boundaries of those lying within our limits are indicated on the accompany-
ing sketch map (figure Hs and certain points concerning their positions are
here diseussed.

|. In idc the following special groupings of provinces are often
found eonven :
“Coastal ‘Plain and adj. provinces.” Plants thus annotated appear
to reach their maximum development on the Coastal Plain, but also occur
northward and westward in the Piedmont, Appalachian Valley, Appa-
lachian Plateau, and other provinces which border the Coastal Plain.
“Various provinces, in Coastal Plain only N.” These plants are not
known to grow in the Coastal Plain within our limits, although they may
be abundant in or even typical of that province further northward, as in
Va., Md., or N. J.
“Blue Ridge and more N Provinces.” In this manner are designated
plants which reach their greatest development in regions north (and north-
west) of our limits, or in some cases in the Rocky Mountains.
s the states of Florida, Mississippi, and Louisiana lie essentially
within the Coastal Plain, plants limited to them have not required spe-
cial mention of province. Moreover, plants occurring “in salt-marshes
along the coast” or “on sand-dunes,” are so obviously limited to the Coastal
Plain that statement of it has been omitted. It is of course realized that
the Coastal Plain is not an ecological unit, being divisible into a consider-
able number of areas with different soils and other features; however, in a
work of the scope of the present volume it is impracticable to go into
details in this respect, which must be left for the writers of local floras.
. While every effort has been made to have these province-assignments

of g spe icd and errors which users of this work may discover

Range.—Instead of eallowiue the usual plan of beginning range state-
ments at the northeast, we begin at the southeasternmost state within our
limits at which the plant is known to occur. When the starting-point lies
toward the eastern coast, the final state named is that lying furthest north-
east, as “Ga. to La., Minn, and Me.” When, however, the start is made
far inland, the last PN given is the southernmost in which the plant ap-
proaches the coast, as “Tenn. to Mo., Mich., N. Y., and Va.” The pri-
mary reason for this method is that his manual covers southern plants,
= and users are naturally most interested in the places where the plant
occurs in the south, hence it is convenient to have the southern limits
come first. There is, however, also a scientific significance to the plan, in
that the last great plant migration on this continent, resulting from the
climatic change connected with the retreat of the ice-sheets of the final
stage of the Glacial Period, consisted in a movement of plants from south
to north, of which the range as stated may give a rough picture.

sided inflorescence and the curved and oblique perianth. G. segetum Ker-
awl, native o e Mediterranean region has a rose-magenta perianth; the
sepals and petals are clawed, the three upper blades ack have a median whitish

2. HICORIA RBaf. Bark close or m Pith solid. Leaflets involute
in vernation. Staminate aments branched. nther-connectiye inconspicuous.
[Carya Nutt.]—About 18 species, natives of eastern North America and
Mexieo.—Many of the hickories furnish a very hard and tough valuable wood.
The fruits furnished a valuable food supply for the aborigines and are ex-
tensively used by the white-man. The bark is used medicinally, and it
furnishes the flavoring ice * ómapleine, ?? a a yellow dye.—Spr.—

too, is drier, more compact, and more spicy in flavor than that of the northern
plant. In Florida the mulberry is largely confined to the sites of abor riginal
activity. Trees extend well to the Cape Sable r region. They are always
deciduous, while the host of associates are evergreen. The fibrous inner bark
was used by the aborigines for clothing and for making other objects.

2. OPUNTIA [Tourn.] Mill. Shrubs or trees, the trunk of fused joints,
more or less irregular, usually widely or diffusely branched, the branches
(joints) flat, armed at the areolae with solitary or clustered spines which
arise from among clusters of bristles, or spineless. Leaves small, fleshy, thick
scales, deciduous. Flowers large, at least relatively so, solitary or several on
a joint. Hypanthium broadened bu) with areolae like the joints. Sepals
fleshy, mostly green. Petals broad, usually broadened upward. Berries longer
than thick, Men is upward, mostly fleshy. Seeds set eochleate, with
ren edges and glabrous sides.—About 260 species, American. —Prickny. -PEARS.
DEVIL’S PINCUSHIONS. TUNAS: DEVIL’S-TONGUES.—The fruits of prickly-
pears are edible. They formed an important food-supply for dis aborigines,
who also used the stems as food by roasting them. The fruits are much used
for food in some countries to-day. In the following descriptions the color
