HITCHCOCK—GRASSES OF CUBA. 201 
2. Paspalum arenarium Schrad.; Schult. Mant. 2: 172. 1824. 
Paspalum simpsoni Nash, Bull. Torr. Club 24: 29. 1897. 
Wright 3443 in part, in National Herbarium, and in Gray Herbarium. 
Spikelets similar to those of P. caespitosum (Wright 3443, in part, in National Her- 
barium), but glandular-pubescent; leaves mostly near the base of the plant, the 
blades ciliate on the margins, otherwise glabrous, flat, less than 10 cm. long, 5 to 6 mm. 
wide; spikes 1 to 3. 
From this P. longepedunculatum Le Conte of the southeastern United States differs 
in having glabrous spikelets and longer, thinner blades. Pittier 1847 from Honduras 
should also be referred to P. arenarium. 
3. Paspalum caespitosum Fliigge, Mon. Pasp. 161. 1810. 
Low wet woods, Pinar del Rio, September, Wright 3443 in part; Cojimar, Baker 
HG 2899, 2903, Hitchcock in 1906; Triscornia, Tracy 9087, [Hitchcock in 1906; Habana, 
Leon 268; Batabano, Hitchcock in 1906; Matanzas, Britton & Wilson 11, 286 in Herb. 
N.Y. Bot. Gard., Britton & Shafer 63 in Ilerb. N. Y. Bot. Gard. 
Grisebach’s specimens of this are labeled ‘‘910=3443” from western Cuba, 1863, 
and “97=3443” from eastern Cuba, 1860. A third ‘'290=3444,” collected in 1865, 
agrees with these and not with 3444 [see P. clavuliferum Wright]. There are two 
sheets of Wright’s specimens in the Gray Herbarium numbered 3444, of which one is 
Paspalum clavuliferum, the other P. caespitosum. The latter is labeled “In crevices 
of rocks in the channel of the river Santa Cruz, Aug. 27.’’ Wright’s 3443 in the Gray 
Herbarium is labeled ‘‘Rocky ridges, Holguin-Barajugua, Aug. 21.” 
4. Paspalum ciliiferum (Nash). 
Dimorphostachys ciliifera Nash in Small, Fl. Southeast. U.S. 78. 1903. 
Arroyo Naranjo, Leon 587; Matanzas, Britton & Wilson 148; Madruga, Britton & 
Shafer 751, both in Herb. N.Y. Bot. Gard. . 
5. Paspalum clavuliferum Wright, Anal. Acad. Cienc. Habana 8: 203, 1871; Sauv. 
Fl. Cub. 195. 
Paspalum falcula Doell in Mart. Fl. Bras, 2°:60. 1877. 
Wright 3444 in National Herbarium. 
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 
P. papillosum.« To P. clavuliferum may be referred Pringle 2359 and 11762 from 
Mexico, and Smith 175 from Colombia. 
6. Paspalum conjugatum Berg. Act. Helv. 7: 129. 1772. 
Roadsides, Hanabana, Wright 767; Herradura, Baker HC 2672, Hitchcock in 1906; 
mountains north of San Diego de los Bafios, Palmer & Riley 541; Santiago de las 
Vegas, Baker HC 2658, 2659, Wilson 543, 1006, [Hitchcock in 1906; Sagua, Britton & 
Wilson 265; valley of the St. Augustine, Britton & Wilson 510, 515; Guajay, Wilson 
342: Habana, Wilson 1277, Leon 302. The following are in the herbarium of the 
New York Botanical Garden: Isle of Pines Curtiss in 1904; Santiago de Cuba, Taylor 
146; Baracoa, Underwood & Farle 1162; Cuba, Rugel 788; Matanzas, Rugel 912.
