Panicum paniculatum Kuntze, Rey. Gen. Pl. 37: 363. 1898. 
Paspalum paniculatum minor Scribn, in Millsp. Field Mus. Bot. 2: 24. 1900. 
A weedy branching perennial, commonly a meter or more tall, the foliage 
harshly pubescent, the flat blades 20 to 30 cm, long, about 1.5 em. wide; racemes 
very numerous, slender, crowded in an oblong panicle, the minute crowded sub- 
hemispheric spikelets pubescent. Exceedingly variable in size and in the amount 
of pubescence. ‘ 
'  Savannas, open or partly shaded, mostly moist ground, Mexico and the West 
Indies to South America; common throughout the West Indies. Originally 
described from Jamaica, the variety also described from that island; P. hemis- 
phericum described from Porto Rico. 
45. Paspalum multicaule Poir. in Lam. Encycl. Suppl. 4: 809. 1816. 
Paspalum papillosum Spreng. Nov. Prov. Hal. 47. 1819. 
A low annual, profusely branching from the base and lower nodes, the sheaths 
and narrow linear blades pilose; racemes a pair at the summit of the culm 
(rarely solitary), divergent, slender, about 3 cm. long, the minute pale orbicular 
spikelets irregularly sprinkled with globular hairs, these often wanting on some 
of the spikelets but present on some on each plant. 
Moist savannas and open ground, Cuba (Province of Pinar del Rfo), Trinidad, 
Brazil, and Bolivia. Both P. multicaule and P. papillosum originally described 
from Brazil. 
46. Paspalum parviflorum Rhode; Fliigge, Monogr. Pasp. 98. 1810. 
A low annual with delicate, repeatedly branching culms, the sheaths and flat 
linear blades pilose with long spreading hairs; racemes 2 or 3, about 5 mm. 
distant, divergent, 10 to 18 mm. long, pilose in the axils, the very minute 
glabrous spikelets solitary. 
Apparently a plant of open moist sand, described from Porto Rico but not 
since collected in any of the West Indies, our specimens being from Guiana and 
Brazil. 
47. Paspalum clavuliferum Wright, Anal. Acad. Cienc. Habana 8: 203. 1871. 
Perennial in small tufts with very slender, sparingly branching culms 25 to 40 
em. tall, pubescent flat linear erect blades, and a pair of slender arcuate racemes 
(sometimes a2 single one) 3 to 5 cm. long, the paired obovate, minutely pubescent 
spikelets 1.5 mm. long. 
Open wet ground, Cuba (Zaza de Tunas and Cajailbana), Porto Rico (Campo 
Alegre, Stevenson 2454), and southern Mexico to South America. Originally 
described from Cuba, Wright 34447* being the type. 
48. Paspalum orbiculatum Poir. in Lam. Encycl. 5: 32. 1804. 
Paspalum pusillum Vent.; Fltigge, Monogr. Pasp. 100. 1810. 
Paspalum lenormandi Husn. Enum. Glum. 12. 1871. 
A glabrous creeping perennial with ascending flowering branches 10 to 20 cm. 
tall, the delicate culms finally branching; blades flat, spreading, mostly 1.5 to 4 
cm. long, 4 to 7 mm. wide; racemes 2 or 3, short-exserted, 4 to 5 mm. distant, 
1 to 2 cm. long, the minute glabrous pale yellow suborbicular spikelets singly 
disposed. 
Wet places, southern Mexico and the West Indies to South America. Orig- 
inally described from Porto Rico; P. pusillum described from St. Thomas, and 
F. lenormandi from Martinique. 
Haiti, Porto Rico, Dominica, Martinique, and Trinidad. 
1Two other species, P. caespitosum and P. poiretii, were also distributed under 
this number,
