No Place but Texas:
An Annotated List of Plant Taxa Endemic to the Lone Star State

Nature Conservancy of Texas
Incomplete
Working Draft, November 2009
Provided below is a list of all plant taxa thought to be endemic to, i.e., found only in, the State of Texas. This distinction has no biological significance, since political boundaries do not correspond to biotic and abiotic forces that effect plant distribution. Nonetheless, this list is offered to satisfy the curiosity of those who wish to know, for whatever reason, which of the state's 5500 to 6000 plant taxa grow only in Texas. Plant taxa that are endemic to the each of the 11 ecoregions that are found, in whole or (mostly) in part in Texas, are available from The Nature Conservancy in other venues.
A list of Texas endemics is not a new idea: two similar unpublished lists have been generated in the past. The first, entitled Endemic Vascular Plants of Texas, probably dates from the mid 1970's. It came to the Texas Natural Heritage Program from the files of the long-defunct Rare Plant Study Center at the University of Texas at Austin. Its authorship is unknown, but legend has it that it was the work of a student of Dr. Chester Rowell, a student who compiled it by painstakingly thumbing through the Manual of the Vascular Plants of Texas (Correll & Johnston, 1970) and writing down every taxon described as endemic to Texas. The second effort was a list of target species for a project entitled Phytogeographical Investigation of Texas Endemics (Amos, 1991). This list was compiled by Dr. Bonnie Amos of Angelo State University. Its concept was broader, including taxa thought to be endemic to major natural biological regions contained mostly within the state as well as most of the traditional political endemics.
All
of the taxa from the preceding efforts were originally included in this list.
Many were deleted on the basis of new information documenting occurrence beyond
the boundaries of the state. Others
were deleted for taxonomic reasons, as new information made it clear that some
of our so-called endemics were not distinct from taxa of other regions. (See "Excluded Taxa" at end of
document.) Conversely, a few
recently-described endemics are included here for the first time.
This
is a work in progress. County
distributions were compiled over the years from voucher specimens as well as a
wide spectrum of published and unpublished literature. However, those sources are not cited
directly in this document. Before any
such list can be published, voucher specimens for each county must be
transcribed. That task has not been
undertaken as yet, in part because the ongoing Flora of Texas project offers
the prospect that such information will be available electronically in a few
years. For the meantime, county records
represented by vouchers at the Plant Resources Center at the University of
Texas at Austin are flagged with asterisks.
The fact that other records are not documented herein is unacceptable
and will be corrected in the future.
Only
a few particularly pertinent literature references are cited. Those providing an illustration of the taxon
in question are flagged with asterisks.
PTERIDOPHYTES
Isoetaceae Quillwort Family
Isoetes lithophila
Pfeiffer. Rock quillwort. Sand and
gravel in shallow water of ephemeral pools on essentially barren granite and
gneiss outcrops on the Llano Uplift.
Burnet*, Gillespie, Llano* and Mason counties. Ref: Correll, 1956*; Correll & Correll, 1975*; Flora of North
America Committee, 1993; Rowell, 1983; Walters & Wyatt, 1982.
ANGIOSPERMS
Monocots
Agavaceae Agave Family
Nolina arenicola
Correll. Sand sacahuista. Windblown
Quaternary sand in dune area east of Van Horn; also in shrublands on steep
Permian limestone slopes in the Guadalupe Mountains. Culberson, Hudspeth and perhaps El Paso counties. Ref.: Burgess & Northington, 1981;
Correll, 1968; Poole, 1989b; Powell, 1998*.
Nolina lindheimeriana
(Scheele) Wats. Lindheimer's nolina.
Grasslands and open juniper-oak woodlands on dry rocky limestone slopes,
mostly on the Edwards Plateau, but ranging north on the Lampasas Cutplain to
Bell and Somervell Counties and south to at least Fayette County. Bandera*, Bell, Bexar*, Comal*, Edwards*,
Gillespie*, Fayette*, Kendall*, Kerr*, Lampasas*, Somervell, Travis* and
Williamson* counties. Ref.: Diggs,
Lipscomb & O'Kennon, 1999*; Lynch, 1981*.
Yucca cernua Keith. Nodding yucca. Known from a six square kilometer area in
west-central Newton County and adjacent eastern Jasper County, where it is
restricted to open or partially shaded upland sites on brownish acid clays of
the Redco Series (Keith, 2003).
Yucca necopina
Shinners. Glen Rose yucca. Grasslands
on sandy soils on terraces of the Brazos River in Hood and Somervell counties
and in deep sands in Parker and Tarrant counties (Diggs, Lipscomb &
O'Kennon, 1999). Ref.: Diggs, Lipscomb
& O'Kennon, 1999*.
Yucca pallida
McKelvey. Pale yucca. Rocky limestone
slopes primarily on the Lampasas Cutplain and in the Cross Timbers, with
reports from Bosque, Brown, Coryell, Dallas, Palo Pinto, Parker, Somervell,
Tarrant and Wise counties; the report from Travis County in Vines (1960) is
doubtful. Reports from the Blackland
Prairie are probably from areas of shallow stony soils rather than deep heavy
clays. Ref.: Diggs, Lipscomb &
O'Kennon, 1999*; Tull & Miller, 1991; Vines, 1960.
Yucca rupicola
Scheele. Twistleaf yucca. The common

Bexar, Blanco, Bosque, Burnet, Comal, Dallas, Edwards, Gillespie, Hays,
Kendall, Kerr, Kimble, Kinney, Llano, Real, San Saba, Somervell, Travis, Uvalde
and Val Verde counties. According to
Mahler (1988), Yucca rupicola ranges
no further north than Bell County, which would seem to indicate that reports
from Dallas and Somervell counties may be based on specimens of Yucca pallida, another Texas
endemic. Ref.: Diggs, Lipscomb &
O'Kennon, 1999*; Enquist, 1987a*; Lynch, 1981*; Rickett, 1970*; Vines, 1960*.
Yucca tenuistyla
Trel. White-rim yucca. Southern
Edwards Plateau and South Texas Plains; county distribution unknown due to lack
of voucher specimens. A poorly known
species, submerged by some authorities (e.g., Vines, 1960) within the more
widespread Yucca constricta.

Mason* counties; a report from Blanco Co. is somewhat anomalous. Ref.: Celarier, 1956; Enquist, 1987a*;
MacRoberts, 1978.

sandy substrates within coastal prairies of the Coastal Bend area. Goliad, Matagorda, Nueces, Refugio and San

subspecies are reported to occur in Texas (Jones, Wipff & Montgomery,
