Third Contribution to the Coastal and Plain Flora of
Yucatan.
CHARLES F. MILLSPAUGH, M.D.
Since the issue of the second of these contributions, this Museum
has been so fortunate as to secure from the widow of the late Dr.
Arthur Schott, his entire herbarium, which includes about nine hun-
dred Yucatan plants collected by him in 1864-66 while engaged by
the Mexican Government to make a geologic survey of the Peninsula.
This collection is of great importance, it being the first really com-
prehensive attempt to collect the flora of this region. It is, however,
to be regretted that Dr. Schott's idea of numeration should have been
that of numbering his collections at home, instead of in the field, and
attempting to group his species of whatever habitat under certain
arbitrary numbers, before such species had been positively ascertained.
This will cause conflict between many of the numbers published in
these contributions and those in the herbaria of the National Museum
and Kew, where part sets of these plants have been previously
deposited by him. A majority of his plants are included in this con-
tribution.
In 1890 an expedition was sent into Mexico under the auspices
of the Academy of Natural Sciences of Philadelphia, and in charge
of Prof. Angelo Heilprin. The work extended from the Orizaba
region to the Peninsula of Yucatan, where Mr. Witmer Stone, the
Ornithologist of the party, incidentally collected about three hundred
plants. These were approximately determined by the late Mr. J. H.
Redfield and distributed, as about ninety-five species, in the herb-
arium of the Academy, whence they have been kindly reassembled
by Mr. Stewardson Brown, and communicated to me for study by
the Academy. These species, so far as determined at this time, are
also included here.
Even a limited opportunity to examine the collections at the
herbarium of Columbia University convinces me that the collection
made by the Hon. E. P. Johnson in Yucatan and Tabasco, in 1848,
345
346 FIKLD COLUMBIAN MUSEUM BOTANY, VOL. i.
is of considerably greater proportions than Professor Helmsley
reports in the botanical volumes of the Biologia Centrali-Americana.
Only a patient overhauling of the whole herbarium can definitely
settle the question of the species in this collection. A few genera in
Leguminosae revealed several plants which I have incorporated in the
following list.
Dr. Geo. F. Gaumer has continued his collections during the
past year. These, so far as determined, form the basis of this con-
tribution, and appear in the text in parenthesized numerals in the
body type the numbers of other collectors being in italics.
To the above collections are added, in the following list, a few
hitherto unclassified numbers collected by the author in 1887, and in
1895 while a member of the Allison V. Armour expedition, and the
remaining numbers of Sr. Porifirio Valdez' century of "Medicinal
Plants" collected in 1895. As heretofore, the species appearing in
black-face type are new to the region covered by these publi-
cations.
Those specialists who have kindly contributed to the knowledge
of the species, are credited under the orders they have worked.

ciliate along the margins, otherwise smooth, or the lowermost
pubescent; ligule a short ciliate fringe of hairs; leaf blade i to
3 inches long, ^ to ^ inch wide, lanceolate acute, smooth,
many nerved, with a narrow cartilaginous margin abruptly nar-
rowed at the base, this contraction forming in the lower leaves,
especially those of the sterile shoots, a slender channeled petiole,
which, like the sheaths, is ciliate along the margins. Panicle
branches, erect or ascending (spreading in anthesis), i to 2
inches long, the uppermost shorter. Spikelets in pairs, one sub-
sessile, the other raised on a pedicel about as long as itself.
Spikelets ovate-lanceolate, acute, glabrous, about 2 lines long;
first glume ovate, acute, strongly 3-nerved, one-half to three-
fourths the length of the spikelet, scabrous on the mid-nerve
above; second glume ovate-lanceolate, acuminate, 5-nerved,
nearly clasping the similar empty third glume ; base of the
fourth glume surrounded by the third; fourth glume about 1.5
lines long, oblong-lanceolate obtuse, 5-nerved, very smooth and'
closely rolled about the palea, which is of similar texture. " Old

short-hairy beneath; while those of the extended virgate branch-
lets are elongated-linear, quite resembling those of var. gramtni-
folia Engelm. This form, but with some of the lower leaves,
panduriform (E. heterophylla cyathophora (Jacq.) Boiss), was col-

Two quite distinct forms of this species are found in our
region : The one with small obtuse slightly and irregularly
crenate leaves (^ to i% inch long by ^ to ^ inch broad), col-
lected only along the coast. (Gaumer, Silam, April, 1895, Schott
Downs at Progreso, April, 1865, 271); the other with large acute
crenate leaves (i to 3 inches long by ^ to 2 inches broad), found
inland (Gaumer 580, Millspaugh, Armour Exped. 60, Schott.
Merida, Jan. 1865, //// and Ruins of Uxmal, Sept. 15, 1865,
643}. The leaves of the form from the coast have a few scat-
tered pilose hairs beneath, those of the inland form scattered
stellate hairs, while in the specimens from the more humid and
higher region of Uxmal the leaves are densely woolly.
