The accompanying paper by A. S. Hitchcock, Systematic Agrostol-
ogist of the United States Department of Agriculture, entitled Cata-
logue of the Grasses of Cuba, is the result of an exhaustive study of
the material in the United States National Herbarium and in the
herbarium of the Estacién Central Agronémica de Cuba. It was
chiefly through the efforts of Mr. Carl F. Baker, who obtained large
. collections in Cuba, that the specimens were made accessible to Mr.
Hitchcock. It is hoped that this paper will be followed by similar
ones upon other groups. |

CATALOGUE OF THE GRASSES OF CUBA.
By A. S. Hrrcncock.
INTRODUCTION.
The following list of Cuban grasses is based primarily upon the
collections at the Estacién Central Agronémica de Cuba, situated at
Santiago de las Vegas, a suburb of Habana. The herbarium includes
_ the collections made by the members of the staff, particularly Mr.
C. F. Baker, formerly head of the department of botany, and also the
Sauvalle Herbarium deposited by the Habana Academy of Sciences..
These specimens were examined by the writer during a short stay
upon the island in the spring of 1906, and were later kindly loaned by
the station authorities for a more critical study at Washington. The
Sauvalle Herbarium contains a fairly complete set of the grasses col-
lected by Charles Wright, the most important collection thus far
obtained from Cuba. In addition to the collections at the Cuba
Experiment Station, the National Herbarium furnished important
material for study, including collections made by A. H. Curtiss,
W. Palmer and J. H. Riley, A. Taylor (rom the Isle of Pines), S. M.
Tracy, Brother Leon (De la Salle College, Habana), and the writer.
The earlier collections of Wright were sent to Grisebach for study.
These were reported upon by Grisebach in his work entitled ‘‘Cata-
logus Plantarum Cubensium,”’ published in 1866, though preliminary
reports appeared earlier in the two parts of Plantae Wrightianae. S
During the spring of 1907 I had the opportunity of examining the
grasses in the herbarium of Grisebach in Gottingen.’ In the present
article I have, with few exceptions, accounted for the grasses listed by
Grisebach in his catalogue of Cuban plants, and have appended a list of
these with references to the pages in the body of this article upon
which the species are considered. The numbers upon the labels of
the Wright specimens in the Grisebach Herbarium are in many cases
- not the same as those under which the species were afterwards dis-
tributed and under which they were listed in the catalogue. These
numbers I have designated as secondary numbers. Grisebach has
sometimes connected on his labels the secondary number by the sign
@Mem. Amer. Acad. n.ser. Vol. VIII. Part I, pp. 153 to 192, (as separate) 1860;
Part II, pp. 503 to 536, (as separate) 1862. The grasses were included in Part IT.
bUnless otherwise stated the writer has examined all the types mentioned in this
- paper:

of equality with the distribution number. The data upon the Grise-
bach labels are meager, usually consisting of the number and year,
together with an abbreviation for eastern or western Cuba. The
distribution numbers of the grasses reported upon by Grisebach are
all below 3500. Wright, after his return from Cuba, studied his col-
lections at the Gray Herbarium and published his results in a series
of articles in conjunction with Doctor Sauvalle, of Cuba.* In the
a Anales de la Academia de Ciencias, Médicas, Fisicas y Naturales de la Habana,
Volumes V to IX, 1868 to 1872. This was reset and, an index being added, pub-
lished in 1873 as Flora Cubana. The introduction to the first installment of the
series (5: 196. 1868) is as follows: ‘‘Revisio Catalogi Grisebachiani vel index planta-
rum cubensium ad catalogum Cl. Grisebachii anno 1866 editum attemperata, pluribus

pro Annalibus Regiae Academiae Scientiarum Havanensis digesta, nominibusque
adjectis cubensibus vulgo receptis a Francisco A. Sauvalle. Setiembre, 1868.”
Each continuation is headed ‘‘Revisto Catalogi Grisebachiani vel Index Plantarum
Cubensium; a Francisco A. Sauvalle.’’ The reprint has a title page as follows: -

reprint, but a comparison of this portion of the original with the reprint shows very
few errors. In the original the serial numbers of the Gramineae occur as follows:

present paper the new species published in Sauvalle’s article are
credited to Wright. The original set upon which Sauvalle’s list is
based is at the Gray Herbarium, and a fairly complete duplicate set
is in the Sauvalle Herbarium.
The sets of Wright’s plants were made up at the Gray Herbarium
and given herbarium distribution numbers. Hach number included
such collections as were thought to be of the same species. Thus it
often occurs that different specimens of the same distribution num-
ber may have been collected in different localities or may even belong
to different species. The data found upon the field labels in various
herbaria are mentioned under each species in the present list. There
is also appended a list of the species of grasses included in Sauvalle’s
Flora Cubana, with references to their identification, and a list of the
Wright numbers in sequence with their identification.
The plan followed in the present paper is to give under specimens
cited a list of the specimens found in the herbarium of the Estacién
Central Agronémica, including the Sauvalle Herbarium, and in the
National Herbarium, without statement as to the herbarium in which
they are deposited. 'To these are added specimens found in the Gray
Herbarium which do not occur in the herbaria just mentioned, and
finally, specimens in the Herbarium of the New York Botanical
Garden (Herb. N. Y. Bot. Gard.), including the herbarium of Colum-
bia University, of which the Torrey Herbarium forms a part, which
are not found in the others mentioned. The specimens collected by
the staff of the botanical department of the Cuba Experiment Station
are numbered in a single series and are indicated in this list by the
letters HC (Herbarium Cubae). The data for the Wright specimens,
given in the paragraph devoted to the enumeration of specimens, are
understood to be found with the specimens in the Sauvalle Her-
barium. Additional data, found with specimens in other herbaria,
are quoted in the succeeding paragraph devoted to notes. :
Grisebach enumerated 154 species of grasses in his catalogue.
Sauvalle’s Flora Cubana includes 170 species. The present list
includes 228 species or well-marked subspecies.

The type in the Trinius Herbarium is from Serra da Lapa, Brazil, though Trinius
in the original publication cites merely ‘“‘V. spp. Brazil.”’ JI. caudata Trin., as
shown by the type in the Trinius Herbarium, differs in having smaller spikelets
(about 2.5 mm. long), longer and more copious hairs, and an elongated inflores-—
cence. The spikelets of J. brasiliensis are 4 mm. long. Wright’s specimen (3486)
is the latter species as shown by the specimen in the herbarium of Grisebach and_
in that of Sauvalle. This is referred to J. caudata by Grisebach@ and Sauvalle.?

This species is named for Mr. George V. Nash, who, while studying the species of
Andropogon in the National Herbarium, suggested that the above-mentioned speci-

The Grisebach specimen is from eastern Cuba in 1860 and numbered ‘‘113=3478.”’
Wright’s 3478 in the Gray Herbarium is from San Juan de Buenavista, Nov. 21.
These were compared with the type of Nees at Munich and that of Trinius at St..
Petersburg (from Martinique, Sveber 262). Thisspecies has an elongated dense panicle,
more or less folded blades, the bent awn twisted below. It ranges from Cuba and
Mexico to Brazil, and is represented in the National Herbarium by the following:
Porto Rico: Heller 934, 4355, 6256; Sintenis 361, 5797; Barrett 101. Santo Domingo:

Rica: Pittier 11005; -Tonduz 3672.. Brazil: Glaziou 17433; Regnell 1414 (111).
Thysanachne scoparia Presl was published in the Symbolae Botanicae, the title
page date of which is 1832 and which, hence, is later than the Reliquiae Haenkeanae.
But the part containing the above species must have been published earlier, for in
the latter work@ is cited ‘““T. scoparia. Presl de thysanachne, 1829. cum icone.’’
There appears to be no such work by Presl except the portion of the Symbolae (pages
11 and 12 and pl. 6) where Thysanachne and T’. scoparia are described asif they were
there originally published. The species is based on Sieber 264 from Martinique.
Presl’s type from Mexico was examined at Prague.

hispidus Willd.), to which he also refers A. brasiliensis Raddi. I have not seen the
type of either of the last two species, but in Trinius’s herbarium is the type of Gold-
bachia mikani Trin., which is included by Pilger in the list of synonyms of A. hispida.
This I consider distinct from A. pallida, as did Nees,¢ and it is what I take to be
A, brasiliensis Raddi. This is also the A. brasiliensis of Hackelin Martius’s Flora Bra-
siliensis, as indicated by plate 38 and by specimens so named received trom Professor
Hackel. The spikelets are smaller and the awn shorter, sometimes scarcely exserted.
This species is represented in the National Herbarium by the following: Mexico:
Liebmann 622,635. Colombia: Pittier 1527. British Guiana: Mount Roraima Exped.
254. Brazil: Glaziou 17921, 20567a; Henschen in 1868, Dusén 3875. Uruguay:

Sheaths and blades pilose, the latter narrow and more or less folded, usually less
than 0.5 cm. wide; panicle rather loose, not elongated as in A. martinicensis; awn
slender and bowed back like a shepherd’s crook, but not twisted. The type of
A. cubensis from eastern Cuba, no. 1552 in 1859, is in the Grisebach Herbarium.
Another specimen also from eastern Cuba, 1860, is numbered “‘115=1552.”’
The types above cited, namely, those of Presl at Prague, Grisebach at Gottingen,
and Trinius at St. Petersburg, agree with each other and are well characterized by
the shape of the awn. Additional specimens in the National Herbarium are as fol- -

aaa: (18. REIMAROCHLOA gen. nov.
Spieler lanceolate, acuminate, solitary, subsessile along one side of a flattened
narrow rachis (the back of the fertile lemma turned toward it), forming few to several
slender racemes, approximate at the summit of the culm, spreading or reflexed at
maturity; glumes obsolete except in the terminal spikelet in which one glume is
frequently present; sterile lemma exceeding the fruit; fertile lemma scarcely indu-
rated, faintly nerved, long-acuminate, inrolled at the ees only, the palea of similar
texture, free nearly Pale its length. i
Perennials of the tropics and’subtropics of the Western Hemisphere.
The genus Reimaria as established by Fligge on the single differentiating character
‘“uniglumis,’’ included three species, the first two of which, R. candida and R. elegans,
differ from Paspalum only in having spikelets without glumes, a character which is
_ unreliable in this group of Paniceae. The third species, R. acuta, together with
those added to Reimaria by later authors, constitutes a distinct genus distinguished
by the characters in the diagnosis above. Considering that Fltigge’s three spe-
cies are not congeneric, but that the first two on the one hand and the third on the
other must be separated, it is necessary that the name Reimaria go with the larger
group.¢ Reimaria then becomes a synonym of Paspalum, or if the glumeless species,
P.candidum H. B. K., P. pulchellum H. B. K., P. elongatum Griseb., etc., be con-
sidered generically distinct, the name would apply to this group. For R. acuta and its
allied species the above name is proposed with Reimaria acuta Fliigge as the type:
Reimarochloa acuta (Fliigge). Paspalum vaginatum Sw. and P. distichum L. (in
which both glumes are occasionally present) in habit and texture of the acute fruits
show a closer affinity to this genus than do the glumeless species mentioned above.

This resembles P. papillosum Spreng., but the spikes are usually solitary instead
of in pairs and the spikelets obovate instead of orbicular. The type of this is in the
Gray Herbarium. The plant in the Sauvalle Herbarium under this number is a
different species, as are the two specimens in the Grisebach Herbarium which are said
to be ‘‘=3444” (cf. P. caespitosum and P. rupestre of this list). Salzmann’s specimen
in Trinius’s herbarium from Bahia, labeled Paspalum horticola Salzm., belongs to
this species. Salzmann’s name was mentioned as a synonym by Steudel under

15. Paspalum lineare Trin. Gram. Pan. 99. 1826.

The type in the Trinius Herbarium is from Brazil, collected’ by Langsdorff, and is
included in the same cover with P. angustifoliwm Nees. Trinius published the latter
name on the same page of the work cited, but preceding P. lineare on the page. The
type is said to be from ‘‘Brazil (N. ab Esenb.).” The type specimen is labeled
“Paspalum angustifolium N. ab Es. In Brasilia. Mis Auctore.’’ This specimen,
however, is not P. lineare, but has, as described, smaller spikelets with rugose trans-
versely wrinkled glumes. P. angustifolium as described three years laterd is the
same as P. lineare Trin., while variety (/ is P. angustifolium as described by Trinius.
Consequently P. neesw Kunth is a typonym of P. angustifolium, since Kunth changes
the name of the latter on account of the earlier P. angustifoliwum Le Conte, but the
name does not apply to the Cuba plant under consideration.

the Grisebach Herbarium bears the label, ‘‘176. Bushy savannas. Hanabana,
June 1.”’
Spikelets sent by Professor Le Comte from the plant supposed to be the type of
Paspalum lindenianum Rich.) show this plant to be the same as P. nanum Wright,
~but this species does not agree with Richard’s description in so far as the blades are
said to be glaucous and glabrous except the ciliate margins, while in P. nanum the
blades are pubescent on the surface. Pending a further examination of the type the
name P. nanum is retained.

I have not seen the type of this species, but in the Trinius Herbarium there is a
specimen labeled ‘‘Paspalum papillosum Sprengel, mis. cl. auctor.’”? The Cuban
plants agree with this, except that the spikelets are less glandular, the flat surface
being quite glabrous. Agreeing with Sprengel’s specimen are two in the Trinius
Herbarium, one collected by Salzmann in Bahia labeled ‘‘ Paspalum horticola mari-
tima Salzm.’’ and another by Riedel at Bahia in 1831. Tonduz’s 4474 from Costa Rica ‘
belongs here. Wright’s 3444 in the Torrey Herbarium is P. papillosum.

The characters which separate this from P. distichum L., the g elabrous spikelets and ~
more or less suppressed midnerve of the glume, may prove to be inconstant. Grise-
bach’s specimen from western Cuba, 1863, numbered 947, is this species. A part of
Wright 1546 (1546a) in the Torrey Herbarium has glabrous spikelets, and consequently

This agrees with Asiatic specimens and may fe introduced. It differs from
E. punctata in the narrower blades and the shorter awn to the fruit.
Allied to these is the Porto Rican Eriochloa subglabra (Nash). (Monachne
subglabra Nash, Bull. Torr. Club 30: 374. 1903; Eriochloa punctata subglabra Urban,
Symb. Antill. 4: 85. 1903). This species differs from LE. ramosa in the broader
blades and pronouncedly velvety nodes, and in habit; from EH. punctata in the
mucronate, instead of slender-awned, fertile lemma, and from both in having a
staminate flower in the axil of the sterile lemma. Urban reduced this to a variety
of EH. punctata without having seen the plant.

The specimen of Wright’s 1544 in the National Herbarium labeled, ‘‘Sandy pine
woods, Pinar del Rio, Sept.,’’ is partly this and partly S. leucocoma Nash. Hackel @
bases his P. curvinerve upon this portion of Wright 1544. The characters which he
mentions, such as the smooth glumes with incurving nerves, are found not infrequently
among specimens of S. filiformis from the northern United States, whence the type
was collected by Kalm. In the specimen of 1544in the National Herbarium (the
smaller portion with spikelets only 1.5 mm. long) part of the panicles have nearly
glabrous spikelets, and part have long-pubescent spikelets. This differs distinctly
from the other part of Wright 1544, which Hackel may have taken for the true
S. filiforms. The amount of pubescence upon the spikelet is quite variable in this
species as inothersofthisgenus. Thesize of thespikelets, however, is fairly constant.
In the Grisebach Herbarium there are two specimens of this from eastern Cuba, one
collected in 1859 numbered 1544, the other in 1860 numbered ‘‘107=1544.”’

a The type species is A. distachya Presl (op. cit. 344), which is published as coming
from Monterey, California, but the type in the National Museum at Prague has two
labels, ‘‘Peruana montana,’’ and ‘‘Regio montana Luzon?’’ The plant is Allote-
ropsis semialata (R. Br.); Panicum semialatum R. Br. Prod. 192. 1810, the type of
which is from New Holland. This is not an American species and Presl’s type must
have come from the Philippines, as indicated by Scribner (Rep. Mo. Bot. Gard.
10: 37. 1899). Presl’s plate and description are incorrect in that the artist incor- —
. porated in the drawing of the spikelet of Alloteropsis a spikelet of an Andropogon
which had become wedged between the glumes and this is described as a second
' pairof spikelets. Although Presl’s genus is founded upon a misconception there is no
doubt as to the identity of the type species. Hence Alloteropsis, the oldest name —
for this group as segregated from Panicum, is accepted for the genus.

green, hispid below and sparsely so above, remotely papillose-ciliate on the car-
' tilaginous margins, 3 to 6 cm. long, 2 to 3 mm. wide, the uppermost much reduced;
spike single, terminating the cma mostly long-exserted, 2 to 3 cm. long; spike-
lets subsessile, appressed to the rachis, alternate, 3 to 4 mm. long, the apex of one
about reaching the base of the one above on the same side; first glume glabrous,
8-nerved, narrow, acuminate to a blunt point, a little shorter than the second,
placed next to the rachis; second glume hispid at the base with a tuft of hairs,
sparsely or copiously hispid above, strongly 5-nerved and with some additional
striz, narrowed to a blunt apex; sterile lemma similar, somewhat gibbous below,
' 7-nerved, its palea obsolete; fertile lemma chartaceous, smooth, and shining, rounded
on the back so as to be as thick as wide, about 2 mm. long, extended into a short
point, the margins flat, not inrolled; palea similar and included in the margins of

Type specimen from Cuba, Wright 3859 no. 559961 in the U. S. National Herba-
rium. The fragmentary specimen in the Sauvalle Herbarium bears the label
aMesosetum Steud. Flora 33: 228. 1850, nomen nudum. The type species of
Mesosetum is M. cayennense Steud., ‘‘Leprieur legit. in Cayenne,’’ the type speci-
men of which, in the herbarium of he Museum at Paris, belongs to the same Spe
3 _ as that of Panicum rottboellioides H. B. K. in the same herbarium.

but not hispid, and glumes and lemmas all notched near the apex, hence some-
what 3-lobed. In Sauvalle’s Flora Cubana Wright 3859 is doubtfully referred to

Wright’s specimen in the Sauvalle Herbarium bears the secondary number 304
in addition to the distribution number. Grisebach’s specimen bears the secondary
number 304 (1865). The specimen in the Gray Herbarium bears the secondary
number 269. Trinius’s type is from Santo Domingo, sent by Sprengel, and is the
plant from which the plate is drawn.¢ The spikelets are about 3 mm. long and
sparsely hispidulous. The culms are’ geniculate and rooting below;.the blades
spreading and 4 to 8 cm. long. A larger form occurs in Florida, with culms as much
as 1 meter high, and blades 15 cm. long and 1.5 cm. wide, the spikelets larger, as
much as 4 mm. long. This is represented in Cuba by Curtiss 748 and Palmer &

‘The first two specimens cited above are like the type at Munich; the others are
more or less pubescent, but appear to be otherwise the same. The type of Pani-
cum proliferum pilosum Griseb. in the Grisebach Herbarium is labeled ‘‘Around
lacunas in wet or damp ground, Hanabana, May 16,’’ no. 186. This is the same
as Wright 3860 in the Sauvalle Herbarium. Probably P. bartowense Scribn. & Merr.@
is a form of P. chlorotwcum. It differs from the Brazilian specimen only in its hispid .
sheaths and from some of the hispid Cuban specimenspnly in itslargersize. Nash’s
567 from Eustis, Florida, is a low spreading form, with culm about 30 cm. long, but
the blades and sheaths pubescent like P. bartowense. P. dichotomiflorum Michx.®
(P. proliferum of American authors, not Lam.), common throughout the eastern
United States, is smooth throughout, and is usually more or less geniculate-spreading
at base, and the blades are usually long and gradually acuminate. In Florida this
shows a tendency to become pubescent. Combs & Rol/fs 94 from Lake City, Florida,
has the habit of P. dichotomiflorum, but the blades are pubescent on the upper sur-
face. The spikelets of P. dichotomiflorum vary in length from 2to3 mm. It would
appear that there is one variable species, including P. dichotomiflorum Michx.,
P. chloroticum Nees, and P. bartowense Scribn. & Merr. The West Indian specimens
resemble more closely P. chloroticum in habit, and for the present they are referred.
to this species. Other specimens of the same in the National Herbarium are: Baha-
mas, Nassau, Curtiss 177; Cat Cay, Brace 3742. Bermuda: Hamilton, Millspaugh 126.

Wright’s 3456 and 3861 cited above have larger spikelets than the other Cuban
specimens (3 mm. long), but this appears to be a variable character. Wright 3456
is the type of P. proliferum strictum Griseb.¢ Wright 3456 in the ee Herbarium

HITCHCOCK—GRASSES OF CUBA. 219
The Grisebach specimen of Wright 3461 also belongs to this species, though it is
listed by him under P. dichotomum variety nodiflorum. Another specimen of this
was included by Grisebach under P. neuranthum; it is labeled ‘‘ a forma ascendens
ramosa.’”’ Wright’s 3461 in the Gray Herbarium is part P. chrysopsidifolium and
part P. lancearium. The two labels are, ‘‘Sandy pe Asiento Viejo de San
Julian, Dec. 1,’’ and ‘‘ Pinal. Mayart, July 24.”
This species is distinguished from P. neuranthum by the pubescent culms, bearded
nodes, spreading vernal panicles, and short, flat autumnal blades on zigzag stems.
The spikelets are 2mm. long. It occurs in Florida and in Porto Rico (Heller 982).
7. Panicum caerulescens Hack. in herb.
Vernal form cespitose, of a somewhat glaucous bluish green color; culms erect or as-
cending, 40 to 75 cm. high, glabrous; sheaths usually less than half as long as the inter-
nodes, glabrous or the basal ones sparingly pubescent; blades ascending or spread-
ing, commonly purplish beneath, glabrous or rarely a few hairs around the base, 5 to
8 em. long, 4 to 7 mm. wide, the margins nearly parallel for two-thirds their length;
panicles usually short-exserted, 3 to 7 mm. long, one-half as wide or less, the branches
narrowly ascending; spikelets 1.5 to 1.6 mm. long, 0.9 mm. wide, obovoid, blunt,
very turgid, glabrous, first glume about one-third the length of the spikelet; second
glume and sterile lemma subequal, the glume scarcely as long as the fruit at maturity;
fruit 1.4 mm. long, 0.8 mm. wide, ellipsoid.
Autumnal form erect or letnine. sometimes decumbent at base, producing short,
densely fascicled branches at the middle and upper nodes, these tufts scarcely as long
as the primary internodes, the reduced blades ascending, more or less involute; the
reduced panicles with only a lew long-pediceled spikelets.
Closely related to P. roanokense, a species of the southern Atlantic coastal plain of
the United States, from which it is distinguished by the narrow panicles and smaller
spikelets and by the tufted branches of the autumnal form.
The type is Hitchcock 706, ‘‘In glade among Spartina, etc., stretching up through
. the tall grass, Miami, Florida, April 3, 1906;” U.S. National Herbarium no. 558380.
The name refers to the glaucous blue color.

has two labels, ‘‘Low wet woods, Hanabana, May 27,’ no. 184 of 1865, and ‘‘Wet—
among tall Cyperaceae, in small bunches, Hanabana, May 25.”’ The plant is 3 feet
tall, stout, with a compressed base, and narrow compact panicle. The other specimen,
which is similar, is labeled, ‘‘Palm savannas, Hanabana, May 18,’’ 1865, no. 197.

Guamaroca, July 25,’’ no. 284, is also included under P. stenodes. <A part of Wright
3870 in the National Herbarium belongs to this species. The type of Richard’s species
in the herbarium of the Museum at Paris agrees with Scribner’s type from Guanica,
Porto Rico,@ a part of which is in the National Herbarium. Nash’s description
applies to these specimens and his type (S7ntenis 3463) was also collected at Guanica,
Porto Rico. Sintenis’s 3365 and 3416, from Guanica, Porto Rico, also belong to this
species. .

HITCHCOCK—GRASSES OF CUBA, 22.5
The Grisebach specimen is from eastern Cuba, 1859, no. 1545. This species has
been referred to P. molle Sw., but the latter is a quite different Brazilian species. It
may be that P. muticum Forsk.¢ is an older name for this species.
Salzmann’s specimen from Bahia, upon which Panicum equinum is based, is in the
herbarium of Professor van Heurck at Antwerp; a duplicate isin the herbarium at
Florence. The specimen from Reugger, Paraguay, also cited by Steudel, is in the her-
barium of the Museum at Paris, and also belongs to this species.

The Grisebach specimens are from western Cuba, 1863, numbered, ‘‘901=3458”’ and
**927=3458.’’ This is listed by Grisebach 5 as P. cyanescens. The type of P. parvi-
folium is in the Lamarck Herbarium at Paris. Wright 3458 in the Gray Herbarium is
‘labeled ‘‘In lagunas (ponds) Los Almacigos, July 28,’’ and ‘‘On tembladeros in

There seems to be an error in the number of the Wright specimen. It is published
as 3451 in Grisebach’s catalogue and in Flora Cubana, and the specimen is so num-
bered in the Kew and the Grisebach herbaria, but in the Sauvalle and the Berlin
herbaria the number is 3457. The Grisebach specimen is from western Cuba, 1863,
numbered ‘‘888=3451.”’
The hairs on the rachis are variable. Curtiss’s 305 in the National Herbarium is
without hairs; the same number in the herbarium of the Cuba Experiment Station
has hairs on some of thespikes. Wright’s 3451 in the Gray Herbarium is from “‘ Retiro,

HITCHCOCK—-GRASSES OF CUBA. 229
There are four specimens of. this in the Grisebach Herbarium: No. 750 labeled
‘Prope villam Monte Verde dictam. Cuba orientali;”” another numbered 750 from
eastern Cuba, 1856-57; a Wright specimen without number or locality collected in
1860-64; and a specimen with proliferous spikelets, numbered 887, ‘‘Cuba occ. Wr.
1863.’ This species not infrequently occurs with proliferous spikelets, as in Palmer
& Riley 130 cited above. The spikelets then consist of many sterile lemmas and
the plants appear as if belonging to the tribe Festuceae.
4. Ichnanthus wrightii sp. nov.
Culms slender, prostrate-spreading, more or less rooting at the nodes, glabrous
or sparsely villous, 20 to 30 cm. long; sheaths mostly less than half the length of
the internodes, striate-nerved, villous on the margins, otherwise glabrous or nearly
so; blades ovate-lanceolate, striate-nerved, faintly 3 to 5-ribbed, glabrous, 12 to
30 mm. long, 2 to 8 mm. wide on the sterile shoots, somewhat larger and thicker
on the ascending flowering culms, all abruptly or cordately narrowed into a slender
stalk 1 to 5 mm. long on the fertile culms, or as much as 15 mm. long on the sterile
shoots; panicles 4 to 8 cm. long, consisting of a few spike-like racemes, 0.5 to 2. cm.
long; spikelets 3 mm. long, glabrous, the pedicel minutely pubescent; lower glume
about half the length of the spikelet, 3-nerved; second glume and sterile lemma
equal, acuminate, strongly 5-nerved; fertile lemma scarcely 2 mm. long, the edges
meeting and covering the palea, except at the very base, the outer margin of the
base of the lemma bearing 4 scar at each side, but no wings.
_ Wright’s 3880. U.S. National Herbarium no. 559959 of this collection is the type.
The specimen in the Sauvalle Herbarium is labeled, ‘‘Under overhanging rocks
(damp) and around base of palms beside the Rio Seco in Arroyo Honda, Pinar del
Rio, Dec.”’ The Grisebach specimen consists of a single spikelet in a packet, labeled
“‘Kchinolaena Sp.’’ no. 760. In the Kew Herbarium there are four specimens num-
bered 2, 23, 244, 760. Nos. 760 and 3880 are also in the Gray Herbarium: This

Wright’s numbers 751 and 1543 in the Grisebach Herbarium are from eastern Cuba,
1859. The latter is numbered 1593 in Sauvalle’s Flora Cubana.
+ It is quite possible that the specimens here included may be referred to distinct
species. The type of Panicum setarium Lam. at Paris resembles Wright’s 1543. The
blades are short and the clusters of spikelets globose and few-flowered: Wright 751

The species of Givetechian here considered are accepted as defined by Scribner and
Merrill. I have not seen the type of Panicum imberbe Poir. nor of Panicum genicu-
latum Lam., which may be an older name for the same. :
In the Grisebach Herbarium are the following Wright specimens: 1. “‘Wet ground
around lagunas, Hanabana, May 16,’’ no. 199 of 1865, a prostrate bunch with culms
15 to 20 cm. long. The bristles are only a little longer than thé spikelets, the spikes
about 1 cm. long, the blades without the scattered long hairs on the upper surface
found in most of the specimens. 2. No. 200 of 1865, which Grisebach has labeled
Setaria glauca a. This also has short bristles. 3. No. 3472, 1860-64, bristles short.

Cenchrus viridis may be distinguished from C. echinatus by the smaller burs and
more incurved involucre lobes.

The locality is not indicated except that the collection was made in eastern Cuba
in 1856-57. This is referred by Doell® to Panicum chaetium Steud. (Chaetium
festucoides Nees), but it differs in many respects. The blades are short and narrow,
mostly involute; the inflorescence is loose, the spikelets few and distant, narrowed to
a pedicel 1.5 mm. long, strongly bearded at the base; first glume very narrow, 22 mm.

In the Gray Herbarium is a specimen of this species from Santarem, Para, collected

brous, the first 12 to 15 mm. long, scabrous on the keel, abruptly cuspidate or awn-
tipped, 3-nerved, one of the lateral nerves somewhat indistinct, second glume 2 to 3
mm. shorter, acuminate, 1-nérved, smooth on the keel, lemma 12 to 13 mm. long,
glabrous, the callus about 1 mm. long, bearded, awns spreading, the central 2 to 3
cm. long, the lateral somewhat shorter.
The type specimen was collected by Wright in Cuba in 1865, no. 41161, in the U.S.
National Herbarium. This specimen is numbered in pencil 2432, which is an error
for 3432. The corresponding specimen in the Grisebach Herbarium was collected in ~
western Cuba in 1863 and is numbered ‘‘928=3432.’’ The only other specimen seen
is: Herradura, Tracy 9076. :
This species resembles A. palustris (Chapm.) Vasey, but differs in having taller
culms, larger and more spreading panicles, and longer glumes and lemma. In A.
palustris the panicle is narrow and strict, the glumes are about 10 mm. long and nearly
equal, and the lemma is only 7 to 8 mm. long.

Other specimens are: Herradura, Mitchcock in 1906; Wright 3427 in Sauvalle

Wright’s 3427 in the National Herbarium consists of this species, together with S.
purpurascens. SS. cubensis is distinguished from S. purpurascens by its larger spikelets,
3.5 mm. long, the elongated blades, and the ferruginous-silky basal sheaths. Heller’s
4590 from Porto Rico is S. cubensis. In the Grisebach Herbarium are three specimens
of this from Wright: No. 3427a of 1860-64; no. ‘‘922—3422” from western Cuba, 1863;
and no. ‘'945=3422” from western Cuba, 1863. (No. 3422 as published in Grisebach’s
Catalogue, is Eragrostis sudans). It will be noted that nos. 3427 and 3427a are the
reverse of what they are in the Sauvalle Herbarium. Wright’s 3427 in the Gray Her-
barium is from ‘‘High pine woods, pinales, Mar. 1;’’ another sheet of this number is
part S. cubensis and part S. purpurascens.

Linneeus cites under Panicum dactylon ‘‘Gramen dactylon, radice repente, S. offi-

genus on this species, though he does not quote a definite author.

Nos. “‘917=1548” and ‘‘932=1548” from western Cuba, 1863, and no. 1549 from
eastern Cuba, 1859. The type of C. brevigluma is in the Gray Herbarium with
printed label for 1860-64, no. 1548. In Sauvalle’s Flora Cubana the type is mis-
printed ‘‘1848 p. p.”’ Wright seems to have distinguished his species from C. eleu-

C. cruciata. Wright’s type matches his no. 1549 in the National Dobe

ADDITIONS TO THE GRASSES OF CUBA
Since the publication of the Catalogue of the grasses of Cuba,3 several
additional species of grasses have been contributed to the National
Herbarium by Brother LEON of the Colegio de la Salle, Habana. The
following is a list of these:
MANISURIS EXALTATA (L. f.) Kuntze, Rev. Gen. Pl. 2:779. 1801.
Stegosia exaltata Nash, N. Amer. FI. 17:84. 1909.
This species is retained provisionally in Manisuris until the genera of
Andropogoneae are more carefully examined.

Marianao, Leén, 779.
PAsPpALUM HELLERI Nash, Bull. Torrey Club 30:376. 1903.
Santiago de Cuba, Leén 951.
PASPALUM MONOSTACHYUM (H. B. K.) Vasey, in Chapm. Fl. South.
Wis: ed; 2..605.. 1830.
Zaza de Tunas, Santa Clara, Leén 947. ‘The spikelets are smaller than in
the typical form.
Paspalum Leoninum Chase, sp. nov.—A low tufted perennial, with
narrow leaves mostly crowded at the base, slender nearly naked
culms and solitary usually purplish racemes. Culms 15-35 cm.
high, very slender, wiry, compressed, ascending or spreading and
more or less sinuous, glabrous, the nodes ascending-pubescent; lower
sheaths overlapping and keeled, glabrous or sparsely pubescent
on the scarious margin and with a few stiff hairs on the auricles,
3 Hitcucock, A. S., Contr. Nat. Herb. 12:183-258. 1909.

Igit| BRIEFER ARTICLES 301
usually but a single leaf about midway on the culm, the sheath
with a few scattered long hairs or glabrous; ligule membranaceous,
about o.5 mm. long; blades flat or somewhat involute from a folded
base narrower than the summit of the sheath, 3-7 cm. long, 1-2
mm. wide, more or less curled, glabrous on both surfaces or minutely
puberulent on the upper, a few stiff hairs on the margin and rarely
on the upper surface, the blade of the uppermost leat reduced to a.
mere tip; raceme 2—3.5 cm. long, slightly curved, a few long hairs
at the base; spikelets solitary, on very short, flattened, scabrous
pedicels, closely imbricated, almost concavo-convex, I.3-1.5 mm.
long, about o.7 mm. wide, oval, glabrous; second glume 3-nerved,
the sterile lemma with a nerve near either margin, the midnerve
suppressed or apparent only at the summit; fruit nearly as large
as the spikelet.
Type U.S. National Herbarium no. 618,754; collected August 30, 1909, on
“Obispo hill, near Sancti Spiritus,” by Brother Leén (no. 950).
This species is most nearly related to Paspalum rupestre Trin., from single-
spiked specimens of which it may be distinguished by the more delicate culms
and the more closely imbricated, glabrous spikelets, the second glume with
the midnerve suppressed.
Paspalum Leoninum is named in honor of Brother LEON, of the Colegio
de la Salle, Vedado, Habana, whose collections have added greatly to our
knowledge of the grasses of Cuba. .
A second collection of this species was made on the Jata Hills, Guanabacoa,
September 12, 1909, Leén 940.

It may be well to record here certain changes in the names of a few
species of Panicum listed in the EIS: as shown by the recent revi-
sion of this group.4 ’
Panicum aquaticum Poir. This is a synonym of P. dichotomiflorum
Michx. The Cuban species is P. elephantipes Nees.
Panicum compactum Sw.=Lasiacis compacta (Sw.).
4HitcuHcock and CHASE, Contr. Nat. Herb. 15:1-396. 1910.
302 BOTANICAL GAZETTE [APRIL
Panicum distantiflorum Rich. To this species was referred Panicum
utowanaeum Scribn. (P. Sintenisii Nash), which proves to be a
distinct species. It is represented by two specimens from Tris-
cornia, near Habana, Hitchcock 141 and Tracy go8o.
Panicum divaricatum L.= LASIACIS DIVARICATA (L.) Hitchce.
Panicum Grisebachii Nash= Lasiacis Grisebachii (Nash).
Panicum hirtivaginum Hitche. This species appears to be the same as
P. Ghiesbreghtit Fourn. of Mexico.
Panicum laxum Sw. To this was referred P. polygonatum Schrad. which,
however, proves to be distinct, and is easily recognized by its
pubescent nodes, and by the lack of the swollen sterile palea which
characterizes P. laxum and P. pilosum.
Panicum numidianum Lam. This species appears to be confined to
the North African area and, though not well known, is sufficiently
distinct from P. barbinode Trin. of Cuba and tropical America.
Panicum Rugellii Griseb.=Lasiacis Rugellii (Griseb.).
Panicum Sellovii Nees. An earlier name is P. millegrana Poir.
Panicum Sloanei Griseb.=Lasiacis Sloanei (Griseb.).
Panicum Swartzianum Hitchc.=Lasiacis Swartziana (Hitchc.).
To these may be added the following two corrections in genera allied
to Panicum:
Mesosetum rottboellioides (H. B. K.) Hitche. A comparison of the type
specimens shows that the Cuban species is Mesosetum loliiforme
(Hochst.) Chase (Panicum loliiforme Hochst. 5).
Hymenachne auriculata (Willd.) Chase. The specimen mentioned, |
Wright 3863 in part, is H. patula Fourn.°—-A. S. Hircucock, U.S.
Department of Agriculture, Washington, D.C.
