1-several dm. long, generally stout, sometimes slender, glabrous, compressed, the nodes hirsute; 
leaf-sheaths much inflated, commonly strongly papillose-hirsute with spreading hairs, usually 
overlapping, compressed; blades 8-30 cm. long, 6-25 mm. wide, flat, glabrous, rough, nar- 
rowed at both ends; inflorescence exserted at maturity, commonly 1-2 dm. long; racemes 
20-100, scattered, or sometimes apparently whorled, 1-13 cm. long, slender, spreading, the 
rachis membranous, 1-2 mm. wide, the apex acute, extending beyond the spikelets; spikelets 
singly disposed in two rows, elliptic, 1.2-1.5 mm. long and about 0.6 mm. wide, pubescent.

13. Paspalum rigidifolium Nash, Bull. N. Y. Bot. 
Gard. 1: 292. 1899. 
A tufted branched nearly glabrous perennial, with narrow flat stiff leaf-blades. Stems 
3-8 dm. tall; leaf-sheaths rather loosely embracing the stem, the basal ones softly pubescent 
with rather long spreading hairs; blades 2 dm. long or less, 3-5 mm. wide, elongate, nar- 
rowly linear, erect or ascending, flat, firm, glabrous with the exception of a row of erect stiff 
hairs just back of the ligule, rarely sparingly hispid or ciliate; racemes single, or rarely in 2’s, 
6-13 cm. long, straight or nearly so, the rachis about 1 mm. wide; spikelets in pairs, 2-2.5 
mmm. long, 1.7-2 mm, wide, oval or broadly obovate, on shorter glabrous or nearly glabrous 
pedicels, the first scale wanting, the second scale glabrous, or more or less pubescent with short 
spreading hairs, 5-nerved, the third scale glabrous, 5-nerved, or sometimes 4-nerved by the 
suppression of the midnerve, the fruiting scale triangular in cross-section, yellowish-white.

ing the stem; blades flat, lanceolate to linear, glabrous or sparingly ciliate, 3 dm. long or less,

rachis 1 mm. wide or less; spikelets in pairs, 1.8-2 mm. long and about 1.5 mm. wide, broadly 
obovate, the first scale wanting, the second scale 3-nerved, glabrous, the third scale 3-nerved, 
or 2-nerved by the suppression of the midnerve, glabrous, the fruiting scale yellowish-white.

15. Paspalum Eggertii Nash, Bull. N. Y. Bot. Gard. 1: 434. 1900. 
A tufted branched perennial with flat glabrous leaf-blades and pubescent spikelets. Stems 
4-6 dm. tall; leaf-sheaths somewhat compressed, the basal ones usually pubescent, the others 
ciliate on the margin; blades flat, the lower ones 5-10 cm. long, or in robust forms sometimes 
2 dm., 6-10 mm. wide, of medium texture, glabrous, lanceolate to linear-lanceolate; racemes usu- 
ally in pairs on the main stem and generally single on the branches, the former long-exserted, the 
latter partly included or somewhat exserted, 4-6 cm. long, the rachis about 0.5 mm. wide; 
spikelets in pairs, about 2.2 mm. long, oval or a little obovate, the first scale wanting, the 
second scale pubescent with spreading hairs, 3-nerved, the third scale more sparingly pubescent 
or glabrous, often 2-nerved by the suppression of the midnerve, the fruiting scale about one 
half as thick as broad, yellowish-white.
