ANNOTATED CATALOGU

OF

Grasses Growing Without C
Louisiana.

The following catalogue of Louisiana grasses represents
the results of collections made during parts of every summer
since 1897, with the exception of two or three quarantine years
when collecting was impossible. During this period the writer
has visited all the extreme portions of the State, both north,
south, east and west, and a very great part of the intervening
territory, especially all parts which have any distinctive geo-
graphic features such as were likely to be accompanied by cor-
responding differences in the flora. There is, of course, the
drawback in such a collection that only one season of the year
is represented, but with grasses this objection is not so great
aL with most other families of plants, as the vast majority
bloom and are in their most perfect condition in the late sum-
mer and early autumn. Consequently while the writer can
hardly hope that this catalogue is exhaustive, it is much nearer
so than could be the case with any other large family collected
only at one season of the year, and no doubt includes a very
large proportion of our wild grasses.

In view therefore of the special interest taken in grasses
by agriculturists and others as shown by the very large number
of enquiries received on this subject, and taking into considera-
tion the fact that none of the published manuals even approxi-
mate accuracy concerning the species which occur in Louisiana,
it seems worth while to publish a list which cannot
be very far from complete, judging from the number here in-
cluded as compared with the number of grasses in other States
cf a similar size.

As the value of such a list depends entirely upon the
authenticity of the identifications, it should be stated at the
outset that there are very few species whose identification rests
solely on the authority of the writer. The grasses collected the
first year or so were all carefully compared with specimens in
the herbarium of Rev. A. B. Langlois, which had been named by
Prof. Vasey of the United States Department of Agriculture.
A few were submitted to the late Dr. Mohr, of Mobile, and
compared by him with specimens in his collection determined
by various experts, while for the past two or three years the
writer has been sending species, especially of Panicum, to Dr.

A. S. Hitchcock, of the United States Department of Agricul-
ture, to whom and to his assistant, Mrs. Chase, the writer de-
sires to express his most grateful thanks for their most courte-
ous and ready assistance not only in determining very many
species, but in clearing up very many perplexities of nomen-
clature and other difficulties.

Unless expressly stated to the contrary, the grasses of this
catalogue are in the herbarium of the writer and were collected
by him personally. Those that remain, between twenty and
thirty in number, are included on the authority of the Rev. A.

B. Langlois, as published in his catalogue, "Provisoire de
Planteis de la Basse — Louisiana, 1887," on the authority of Dr.
Chas. Mohr, in his "Flora of Alabama," of Prof. Small in his
"Flora of the Southern States," and of Dr. A. S. Hitchcock
and of Dr. Lamson ScribDer, in various monographs on certain
families published )>y the United States Department of Agri-
culture.

In this list reference has not been given to every pub-
lished description and figure of the species, but the writer has
selected the four publications in which ean be found descriptions
and figures of most of them. These are Britton & Brown, "Illus-
Small Flora of the Southeastern United States; Beale Manual
of Grasses of North America, and American Grasses, Vols.
I and IT, published by the United States Department of
Agriculture.

No previous attempt has been made to publish a com-
plete list of the grasses of the State, for the early floral cata-
logue of Riddell, Hale & Carpenter did not include grasses,

and Feather-man's list in 1870 and that of Langlois in 1887
only included portions of the State, consequently a very
lariM' iiiuubiT <>t' species are here recorded for the first time
as occurring in Louisiana.

The geographic position of Louisiana makes the plant
distribution of peculiar interest, for not only does its situ-
ation on the verge of the tropics make it the northern bound
any line of many southern plants and the southern boundar)
line of many northern plants, but it is equally on the boundary
line of* the Eastern and Western divisions of the continent, so
that here again many Eastern species have their Western
limit, and many Western species their Eastern limit, the
number of this last division being particularly large.

While it is not possible to say of each species exactly
what its limits are, the following seem to be undoubted in-
stances of each of the above named divisions :

(I) Grasses which have their northern limit in Louisiana.
— Panicum leucophaeum, Panicum pyriforme, Panicum albo-
marginatum, Panicum pseudanceps, Panicum manatense, Pani-
cum paspaloides, Luziola Peruviana, Aristida palustris, Erio-
clrfoa punctata, Paspalum conjugatum, Paspalum vaginatum.

(II) Grasses which have their southern limit in Louisiana.
— Panicum Roanokensc, Panicum nitidum, Panicum filmiculme,
Brachyelytrum erectum, Agrostis. perennans, Holcus lanatus,
Dactylis glomeratus, Panicularia fluitans, Pohjpogon Mons-
peliensis.

(III) Grasses which have their western limit in Louisi-
ana.— Echinochloa longearistata, Panicum verrucossum, Pani-
cum lanuginosum, Panicum. Joorii. Ccnclirus machroccpJialvs.
Hydrochloa fluitans, Stipa avencea, Sporobolus Drummondii
Danthonia sericea, Gymnopogon brevifoUus.

(IV) Grasses that.have their eastern limit in Louisiana.
— Amphilophis exaristata, Paspalum li rid ton. I 'us /ml um Drum-
mondii, Panicum platyphyllum, Panicum Helleri, Bonteloua
hirsuta, Tridens Tc.ranus. LeptocJdoa imhricata, L< ptochloa
Nealleyi, Diplachnc Halei.

There are many other instances, but these arc sufficient
to show that Louisiana is the meeting ground of these four
divisions of the Flora of the continent. It is also interesting

6

to note that of the 290 species of grass here listed no less than
169 have a range northern enough to be included in Britton.
& Brown's manual; i. e., to the southern boundary of Virginia
and Kentucky. About twenty-five species seem to be undoubt-
edly introduced European species, and some six or eight Asiatic,
but the writer has not been able to decide exactly how many
species are native and how many are introduced from elsewhere.

The following species, according to Prof. Small's Flora,
occur in Louisiana only of the United States : Panicum proa
tratum, Luziola Peruviana, Trisetum Loudovicianum, Leplo
chloa scabra, Vetiveria Zizanioides.

A comparison with the grasses of Alabama as set forth by
Dr. Mohr shows that the two States have about the same number
of grasses, though no doubt Alabama has been much more
thoroughly explored than Louisiana, which may eventually
prove to have a good many more. Of these, 190 species, or
about 65 per cent, occur in both States, the proportion of
grasses to the whole flora also seems to be nearly the same
in both, perhaps slightly larger in Louisiana. According to
Dr. Mohr grasses form somewhat over 11 per cent of the flora
of Alabama, while of the writer's collection of Louisiana
plants, grasses form about 12 per cent.

The accompanying notes relative to the distribution of
grasses in the State are necessarily extremely imperfect and
many of the grasses are distributed much more widely over
the State than the writer has observed them.

In conclusion, the writer desires to express his thanks to
the Board of Managers of the Gulf Biologic Station for sub-
stantial help during the past two years in collecting material,
and especially to Prof. B. H. Guilbeau, the Director of the
Station, at whose suggestion this paper has been prepared,
for every courtesy and assistance.
