Paspalum Edmondi Fr. Leon, sp. nov. 



A small tufted perennial with short rhizomes and numerous 

 slender pubescent leafy branching stolons; stems simple, very 

 slender, compressed, glabrous, 2-6 cm. long; leaves crowded at 

 the base ; sheaths pilose ; ligule membranaceous, 0.5-1 mm. long ; 

 blades lanceolate to linear, pilose on the upper surface towards 

 the base and near the lower margins, glabrous beneath, 11.5 cm - 

 long, sometimes up to 6 cm. long in the specimens grown in a rich 

 soil, 1-2 mm. wide, flat or somewhat involute towards apex; 

 racemes solitary, up to 12 mm. long, usually about 6 mm., with a 

 tuft of hairs at the base ; rachis 0.5-0.7 mm. wide, glabrous ; 

 pedicels shorter than the spikelets ; spikelets solitary, with a short 

 wing along the pedicel, somewhat imbricate, 1.5-2 mm. long, 1-1.2 

 mm. wide, ovate, abruptly acuminate-pointed; first glume want- 

 ing, second glume glabrous, often transversely wrinkled, 7- 

 nerved, conspicuously pointed ; sterile lemma glabrous, more or 

 less deeply hollowed between the strongly elevated, rugose, some- 

 times tubercled margins, nearly as long-pointed as the second

Palm barren, sabana de Motembo, Santa Clara {Leon & Ed- 

 mond 8607) . 



Specimens from the same locality were transplanted in 

 Vedado, Havana {Leon & Edmond 8682). The type specimens 

 are preserved in the Colegio De La Salle Herbarium, Vedado, 

 Havana. 



Paspalum acutifolium Fr. Leon, sp. nov. 



Perennial, tufted; culms simple, erect or ascending, glabrous, 

 compressed, nearly naked, much exceeding the leaves, these 

 densely crowded at the base ; nodes clothed with long white hairs ; 

 sheaths striate, keeled, mostly overlapping, glabrous, sometimes 

 sparsely hispid towards the summit, hirsute-ciliate, the upper 

 ones bladeless or nearly so ; ligule membranaceous up to 2 mm. 

 long; blades firm, rarely over 15 cm. long, 4-8 mm. wide, sparsely 

 papillose-hispid on both surfaces and the margin when young, 

 mostly flat or conduplicate, sometimes twisted, involute towards 

 apex, the middle nerve prominent beneath ; inflorescence termi- 

 nal ; racemes 2 to 4, the common axis 1-3.5 cm - l n &> with long 

 white hairs at base ; racemes straight or slightly curved, diver- 

 gent, rarely spreading; rachis about 1 mm. wide, bearing a few 

 long hairs at the base, otherwise glabrous ; spikelets normally in
