glume; palea smaller, 2-dentate, closely wrapping the stamens. 
Upper flower hermaphrodite, smaller than the male, its flower-

Elegant grasses, with slender panicles of silky, white or rosy flowers.—5

Rhynchelytrum, Nees, |.c. p. 64, seems to be the same genus with rather

glumes. 
9. GYMNOTHRIX, R. Br. 
Spikelets and flowers of Panicum, but each spikelet sur- 
rounded by an involucre of long, simple, unequal, awn-like

10. PENNISETUM, Beauv. 
Spikelets 2-flowered, spiked, each with an involucre of two 
sorts of bristles; the outer bristles short, slender, scabrous ; 
the inner longer (very unequal), feathery in the lower half. 
Outer glumes either 2, the lower minute; or 1, the lower 
being deficient ; membranous, subscarious, acute. Lower 
flower male, with flowering glume and palea, or neuter without 
palea; the flowering glume membrano-scarious, 3-fid. Upper 
flower either hermaphrodite or female. Glume and palea

11. ANTEPHORA, Schreb. 
Spikelets 1-5, in a 4-5-fid hardening involucre, composed of 
the united lower glumes, arranged in simple, unjointed spikes. 
Second glume membranous, subulate, short; supporting a 
neuter, membranous flowering glume, and above it a herma- 
phrodite flowering glume. Flowering glume and palea of the 
fertile flower papery, concave, subequal, hardening in fruit 
and enclosing the mucronulate grain.— ees, l.c. p. 73.
