HITCHCOCK AND CHASE—GRASSES OF THE WEST INDIES. 391 
13. Eragrostis cubensis Hitchc. Contr. U. 8S. Nat. Herb. 12: 248. 1909. 
Similar to the prececing, commonly taller, the culms branching, the blades 
laxer; inflorescence a nearly simple panicle, the spikelets longer, less firm. 
Immature or depauperate specimens may be distinguished from H. bahamensis 
by the pilose, not woolly, tapering or truncate, not auricled summit of the 
sheath. . 
Sandy or rocky soil, Cuba and Jamaica (Lititz and Southern Manchester). 
Described from Cuba, Curtiss 420, from the Isle of Pines, being the type. Grise- 
bach’ refers this species to H#. bahiensis Schrad. 
14. Eragrostis berteroniana (Schult.) Steud. Nom. Bot, ed, 2. 1: 562. 1840. 
Megastachya berteroniana Schult. Mant. 2: 330. 1824, 
Poa berteroniana Kunth, Rév. Gram. 1: 112. 1829. 
This little-known species was described from Santo Domingo, where it was 
collected by Bertero. There is in the Krug and Urban Herbarium a portion 
of the type specimen which was received from the Sprengel Herbarium. There 
is also in the Trinius Herbarium a specimen from the same collection. No 
other collections have been seen. The species differs from Hragrostis cubensis 
in having villous sheaths and a more open panicle. 
15. Eragrostis elliottii S. Wats. Proc. Amer. Acad. 25: 140. 1890. 
Poa nitida Ell. Bot. 8. C. & Ga. 1: 162. 1816, not Poa nitida Lam. 1791, nor 
Eragrostis nitida Link, 1827. 
Eragrostis macropoda Pilger in Urban, Symb. Antill. 4: 106. 1903. 
Tufted, about 50 cm. tall, the rather stiff leaves mostly clustered toward 
the base, the very diffuse few-flowered panicle more than half the entire 
height*of the plant, the panicle axis and the capillary branches fragile. 
Sandy savannas and sterile hills, southeastern United States on the Coastal 
Plain and in the West Indies. Originally described from South Carolina. 
Eragrostis macropoda was described from Catafio, Porto Rico (Sintenis 1233), 
the author differentiating it from “ #, elliotti” by the elongate pedicels. Pil- 
ger’s observations, however, show that he was really distinguishing it from 
EB. refracta (Muhl.) Scribn., which he supposed to be £. elliottit. 
Bahamas (New Providence, Abaco, Eleuthera), Cuba, Jamaica (Lititz and 
Southern Manchester), Santo Domingo, Porto Rico, and St. Thomas. 
16. Eragrostis acutiflora (H. B. K.) Nees, Agrost. Bras. 501. 1829. 
Poa acutifiora H. B. K, Nov. Gen. & Sp. 1: 161. 1816. 
Tufted, rather rigid, with sparingly branching culms and erect blades, the 
short-pediceled spikelets approximate along the distant, stifly spreading primary 
panicle branches. 
Ditches and open moist soil, northern South America. Found in Trinidad 
(Piarco Savanna, Hitchcock 10844). Originally described from Colombia. 
17. Eragrostis purpurascens (Spreng.) Schult. Mant. 2: 317. 1824. 
Poa purpurascens Spreng, Nov. Prov. Hal. 33. 1819. 
Culms ascending or spreading, sparingly branching below; panicles com- 
monly about one-third the entire height of the plant, about two-thirds as wide 
as long, the slender flexuous branches, branchlets, and pedicels divergent; 
spikelets about 8 mm. long, dark-colored, the lemmas thin, the lateral nerves 
obscure. 
Open ground and rocky hills, Brazil to Argentina; also in Antigua (Duss 8: 
Wuilschlaegel 644). Originally described from Uruguay. This is the species 
described by Grisebach* as Eragrostis prolifera. The plants from Antigua 
*F1. Brit. W. Ind. -532. 1864.
