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. Pitlier 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 

 HC 2899, 2903, Hitchcock in 1906; Triscornia, Tracy 9087, Hitchcock in 1906; Habana, 

 Leon 268; Batabano, Hitchcock in 1906; Matanzas, Britton & Wilson 11, 236 in Herb.

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 cUiifera 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 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. a 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 Banos, 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 & Earle 1162; Cuba, Rugel 788; Matanzas, Rugel 912.
