the fertile and male spikelets coriaceous, hardening, with 
scarcely obvious, immersed nerves; in the neuter spikelets 
membranous, nerved. Flowering glumes thinly membranous, 
ciliate ; the lower neuter; the upper fertile, with a short, 
twisted awn, or awnless ; palea small, narrow. Scales fimbri- 
ate. Grain thick, short, hard, closely wrapped in the hardened 
glume and palea.—WVees, l.c. p. 85. 
Tall, strong, broad-leaved grasses, with villous or pubescent glumes. 
Grain used for food in India.—2 Cape species. 
27. CHRYSOPOGON, Trin. 
Spikelets bearded at the base in threes at the ends of the 
branches of an erect panicle, central one sessile, hermaphro- 
dite ; 2 lateral ones pedicellate and male. Outer glumes 2 ; 
in the fertile spikelet the lower is 4-nerved, blunt or short- 
pointed, the inner decidedly keeled and long-pointed ; lowest 
flowering glumes neuter, hyaline ; upper fertile, long-awned, 
palea wanting; in the pedicellate spikelets both glumes are 
pointed, awnless, and without palea ; one flower male, the other 
neuter. Grain small, oblong.—Zrin. Fund. p. 188; Icon. p. 
331; Benth. l.c. p. 424. 
Erect, 1-2 feet high in Cape species, leaves fringed, somewhat waved.—1 
Cape species, found near the Gariep by Burchell. 
28. ANTHISTIRIA, Linn. 
Spikelets heterogamous, in simple or 2-3-fid tufts, several 
sessile awnless male or neuter spikelets surrounding a single 
awned fertile sessile spikelet, and 2 male or neuter pedicelled 
ones. Structure of the fertile spikelets similar to that of 
Andropogon. Grain free, enclosed in the hardened glumes.— 
Nees, l.c. p. 120. 
Grasses resembling Andropogon, differing in inflorescence.—4 Cape spe- 
cies; A. ciliata is common.

29. COIX, Linn. 
Spikelets moneecious. Males above spiked in threes at the 
joints, 1 pedicelled and 2 sessile, all with 2 flowers; fertile 
sessile, 2-flowered ; lowest flower neuter, upper female, sup- 
ported by 2 neutral, pedicelled spikelets, which are occasionally 
abortive, remaining enclosed in the bony: involucre, through 
the top of which the peduncle carrying the male spikelets 
emerges. Outer glumes in male spikelets 2, about equal in 
length, the lower flattened and winged on the margins, the 
upper keeled. Flowering glumes and pales membranous and
