CHECKLIST OF THE VASCULAR FLORA OF FLORIDA
PART I.
Psilopsida, Lycopsida, Sphenopsida, Filicinae,
Gymnospermae, Monocotyledoneae.
Daniel B. Ward I
INTRODUCTION
This Checklist records the names of those species of vascu-
lar plants found native or naturalized in the state of Florida.
Part I, published here, includes the ferns and other non-seed-
bearing plants, the cone-bearing species, and that portion of
the flowering plants known as the monocotyledons; Parts II
and III will contain the larger portion of the flowering plants,
the dicotyledons. The non-vascular plants, those species with-
out specialized conducting tissues, will not be included.
The information given in this Checklist is restricted to the
minimum necessary to encompass the nomenclaturally correct
names of the included species, with sufficient synonymy to as-
sociate these names with those used by the most comprehen-
sive author on the southeastern flora, J. K. Small. Common
names are also provided, where such names are available and
when they are believed to be in current use. No infraspecific
taxa subspecies, varieties, or forms are recorded in this
list, although in many cases the existence of such lesser cate-
gories is apparent in both the field and the herbarium.
Origin and Number of Species
The flora of Florida is formed of several components, re-
flecting the area of origin of the individual s p ecie s. The
largest component, perhaps as much as half of the entire flora,
is of North American derivation and contains the species
familiar on the Coastal Plain of the southeastern United States
that reach their southernmost limit in Florida. A large group
of species in the state is clearly of tropical origin, with rep-
resentatives occurring in the eastern United States only in
southern Florida; among these species lie many of the more
difficult taxonomic problems. Approximately 10%o of the species
in Florida are endemics, that is, species restricted in their range

to the state; probably no other state east of the Mississippi
has more than 1 or 2% endemism. And finally, many species
may be explained as chance or intentional introductions associ-
ated with the activities of man.
A considerable number of species customarily reported to
range into Florida have been excluded from this Checklist. For
many of these no supporting specimen could be located, for
others the only record is an early collection with imprecise
(often only "Florida") and possibly erroneous data. As a gen-
eral rule, if a name is included in this list, a specimen of that
species from the state has either been seen by the writer or is
cited by a monographer of the appropriate genus. Other pub-
lished statements have been used solely as aids to further
search. In case of doubt, the consistent practice has been to
exclude a species that might possibly be in Florida, rather than
to include one that possibly is not.
This Checklist records 1183 species in 318 genera. Insofar
as this listing can serve as an indication, the entire vascular
flora of the state of Florida exceeds in number that of any other
state in the eastern United States and is perhaps surpassed in
this country only by the floras of California and Texas. On a
comparative basis (i. e., dicots excluded), using as examples
some states of roughly equal area in which the flora is well
known, Indiana contains 705 species, Missouri has 715 species,
and the diversified topography of North and South Carolina
supports 1033 species.
South of Florida, floras are consistently larger in tropical
areas of equivalent size. The conifers and monocots of Cuba
total 1303 species. (Data on number of ferns and "fern allies"
are unavailable; a comparative figure for Florida, excluding
these groups, is 1058.) A compilation for Costa Rica, reflecting
a wealth of orchids and other tropical forms, gives 1955 species
of conifers and monocots.
Scientific Names
Each species recognized in this Checklist is denoted by a
scientific name. When given in full, a scientific name consists
of three parts a genus, a species, and an author. Such names
are intended, by international agreement, to serve as a univer-
sally recognizable indicator of the species to which they are
applied, thus permitting precise understanding of the plant
under discussion regardless of language or nationality.
The genus and the species of a plant are either in Latin or
are treated as Latin. The author is an indication, usually ab-
breviated, of the person who first described the plant. Often
there is also the name of the person who first placed the plant
in its present genus, or at its present taxonomic level. The first
plant in the present list, for example, the whisk-fern, was first
described by Linnaeus in 1753 as Lycopodium nudum and was
transferred to its correct placement in the genus Psilotum by
Palisot de Beauvois in 1805; the full name of the plant becomes
therefore Psilotum nudum (L.) Beauv.
All scientific names used in this Checklist have been pub-
lished previously. The names are believed legitimate, in the
narrow sense of the International Code, although it has not been
possible to confirm this in all cases. Where the application of a
given name differs from that of recent authors, the writer is
reasonably confident that his usage is the correct one.
The plants of this Checklist are grouped not only into genera
but into higher categories indicating their common relation-
ships. The most important of these is the rank of family, a
category containing one or more genera of presumed close
evolutionary origin. All family names (with the exceptions in
Part I of the Gramineae and Palmae) may be recognized by
the ending -aceae.
Above the level of family are recognized, where appropriate,
the ascending levels of subclass, class, subdivision, and division.
These categories are in conformity with a widely used, although
far from universally accepted, schema of classification pro-
pounded by Tippo,2 as a synthesis of several earlier arrange-
ments.
Synonyms
The works of John Kunkel Small have remained, since his
death in 1938, the most important single source of information
on the taxonomy of the plants of the Southeast. Neither this
Checklist nor any other study of the flora of Florida can be
complete without consideration of Small's numerous botanical
papers and comprehensive books. In the present list, whenever
the name used by Small in two of his more important works
(Manual of the Southeastern Flora, 1933; Ferns of the South-
eastern States, 1938) differs from the name here considered
correct, Small's name is listed in Roman type below the accepted
name.
The works of J. K. Small are characterized not only by a
2 Tippo, 0. 1942. A modern classification of the plant kingdom. Chron.
Bot. 7: 203-206.
high degree of overall competence and keen insight into the
relationship and diagnostic characteristics of plant groups, but
by what appears to be a disconcerting originality in the use
of scientific names. All too often the name used by Small is not
the same as the one employed for the same plant by other
respected authors. Commonly the specific epithet is different,
frequently a familiar specific name appears following an un-
familiar generic name, and perhaps most disturbingly, in a
sprinkling of cases, a well-known name, consistently used by
other authors for a particular plant, is employed by Small for
an entirely different species.
These apparent nomenclatural peccadilloes of Small's, al-
though a serious impediment to the user of his works, are not
the consequence of mere whim, but stem in large part from two
of his policies, firmly held and consistently applied. The first of
these was his belief that if a taxonomic group is sufficiently dis-
tinct to be worth recognizing, it should merit specific rank;
only with great rarity did he recognize varieties or other in-
fraspecific levels. Similarly, if a group of species shows even a
small number of common characteristics, the group should merit
separate generic rank. This policy yielded many segregate
species and genera which are not recognized at those particular
taxonomic levels by most modern authors. In this Checklist one
need look for examples no further than the genus Selaginella, by
most authors treated as one genus, but by Small considered to
be divisible into true Selaginella and a segregate, Diplostach-
yum; similarly, Small recognized Selaginella arenicola and S.
acanthonota as two distinct species, while recent authors have
treated them as subspecies or varieties of a single species.
A second policy of Small's which has unfailingly caused
difficulty was his devotion to a set of rules of nomenclature, the
American Code, promulgated by his employer, Nathaniel Lord
Britton of the New York Botanical Garden. The American
Code, never fully accepted in the land of its origin, was rejected
by the botanists of Europe, and became of only historical in-
terest after the near-universal approval in 1930 of the present
International Code. Yet Small, beyond this date, consistently
used a set of rules governing the naming of plants that differed
in several significant points from the rules of the International
Code. Most striking, in terms of the number of name changes
caused by this unyielding conformity to the American Code,
are the generic names which differ in Small's works and those
of all modern authors as a result of the preservation in the
International Code, as what are termed nomina conservanda, of
generic names commonly used but later in date of publication
than other, relatively unfamiliar names. Thus, the water-hya-
cinth is correctly known in the genus Eichhornia, a name not
published until 1842, rather than in the genus Piaropus, which
dates from 1837. Similarly, the zephyr-lilies belong in the genus
Zephyranthes, an 1821 name, rather than in Atamosco, pub-
lished in 1763.
Common Names
Very often the precision of understanding that is the central
purpose of the use of scientific names is met, at least on a local
basis, equally well by a well-selected and narrowly applied com-
mon name. Many plants have such common names, and when-
ever they are known to the writer, these names have been in-
cluded in the present Checklist.
A degree of editorial license has been applied to the selec-
tion of a "best" common name, where more than one is applied
to the same plant, or where the same common name is used
for two or more different plants. In a number of instances,
in a dilemma familiar to all writers of floristic treatments,
a widely used but scarcely printable common name has been
rejected for an innocuous synonym. Whenever two or more
common names for a plant are believed to be in widespread
use, and of equal suitability, this Checklist uses the name
that has been selected in two of the more comprehensive efforts
to establish uniformity in the application of common names.3
Since the names of these standardized lists are drawn, at least
in part, from the same sources as the names in this Checklist,
a large proportion of these common names will be found to
be identical.
The concept is rejected, however, that there can be a single
"standardized" common name for a plant, for common names,
by the very meaning of the phrase, are of "common" origin
and are not established by the application of uniform rules
or by consistent usage in scientific publications. Naturally,
true common names often lack precision as to what plants
are referred to, but this is a function better left to the uni-
versally applicable scientific name and, in any event, is not
achieved by the standardization of common names within a

single country, when the plants themselves are not so limited.
The "standardized" common name, in its more artificial
form, all too often appears as a mechanical translation of the
scientific name: thus, Eleocharis acicularis becomes slender
spikerush; E. obtzusa, blunt spikerush; E. parvula, dwarf spike-
rush; and E. quadrangulata, squarestem spikerush. The fri-
volity of these names becomes quite apparent when one con-
siders that these species, together with a score or more of
others, are very closely related and in many cases cannot be
distinguished except by microscopic examination. Such syn-
thetic common names are excluded from this Checklist.
Considerable effort has been given to reflecting, by the
way the common name is spaced or hyphenated, the actual
relationships of the plant. Thus, Rhoeo spathacea is known
as boat-lily and Asparagus plumosus as asparagus-fern, since
the first is not a lily and the second is certainly not a fern,
while Lilium catesbaei is known as pine lily and Nephrolepis
biserrata as sword fern, with common names reflecting their
true alliances. Occasionally, where long-established usage has
made the adjective an integral part of the name, the combined
form is accepted, as in clubmoss, pondweed, and bluegrass,
but such barbarisms as Bermudagrass and St. Augustinegrass
have been avoided.
Supplemental Literature
Considering the richness and uniqueness of the Florida
flora, a relatively limited list of publications is available dealing
with the identification of the native and naturalized plants.
Only certain genera and a very few families have been treated
in sufficient detail. In most cases one must depend upon regional
studies, which of necessity give scant information about the
flora of any single state. The following publications, some of
which are semi-popular and others comparatively technical,
are important aids in the identification of the flora of Florida.

Acknowledgments
The preparation of this Checklist has been aided by the
many persons who have supported and assisted in the building
of the Herbarium of the University of Florida, the major
repository of information upon which this list is based. I have
drawn freely upon the published work and upon personal cor-
respondence with botanists who have dealt with the South-
eastern flora. The late Professor Erdman West and Dr. Robert
K. Godfrey, in particular, have contributed to my understand-
ing of many genera.

Pinus clausa, sand pine, is the characteristic tree of Florida's white-
sand-scrub habitat. Sand pine is found in many scattered areas in most
parts of the state and extends outside Florida only into coastal Alabama.
Left to right across bottom:
Sphenostigma coelestinum, Bartram's ixia, is a beautiful violet-flowered
relative of the iris which blooms for a few hours in the early morning, the
flowers withering in the full sun. Bartram's ixia, discovered by the pioneer
