456 CXLII. GRAMINER. 
80. BROMUS, Linn. 
Spikelets many-flowered, in loose panicles. Outer glumes 
membranous, unequal, pointless, shorter than the flowering, the 
lower 1—7-nerved, the upper 3-1l-nerved. Flowering glumes 
convex and moderately keeled, under the 2-dentate apex seti- 
gerous or entire and pointless, with 7 primary nerves; palea 
infolded, entire or 2-fid. Ovary pubescent at the apex. Grain 
mostly attached to the palea.—WNees, l.c. p. 450. 
A large, widely-spread genus.—6 Cape species. 
81. CERATOCHLOA, Beauv. 
Spikelets many-flowered, compressed, in spreading panicles. 
Outer glumes subequal, shorter than the lower flowering 
glumes. Flowering glumes imbricate, with a callus at base 
and palea sharply keeled, setigerous under the apex. “ Ovary 
3-horned ” (Wees).—Lees, 1. c. p. 449. 
C. unioloides, an American grass, is naturalized about Capetown. 
82. CYNOSURUWS, Linn. 
Spikelets in spike-like, secund panicles, 2-5-flowered, inter- 
mixed with pectinate abortive spikelets or cut-glumes. Outer 
glumes 2, lanceolate, membranous, 1-nerved, keeled, shortly 
awned. Flowering glume convex, 5-nerved, mucronate or 
awned; palea membranous, 2-nerved, folded, 2-toothed. Grain 
glabrous, adherent.— Nees, l.c. p. 439. 
Rigid, narrow-leaved grasses.—2 Cape species ; one scarcely different from 
C. echinatus, Linn. 
83. EHRHARTA, Thunb. 
Spikelets 1-flowered, compressed, panicled. Outer glumes 
membranous, pointless, often short; within there are 2 inner 
hard and dry, strongly keeled, mucronate or subulate-awned 
empty glumes. Flowering glume and palea membranous or 
subcoriaceous, keeled; palea shorter and narrower. Stamens 
6-3. Grain covered by the flowering glume and palea.—Wees, 
l.c. p. 196. 
A large genus, containing 24 Cape species, of very elegant grasses ; the 2 
inner empty glumes often ribbed and furrowed crosswise. 
An interesting link between ordinary Festucacee and Bambusee. 
SUBTRIBE 7, BAMBUSER®. 
84. NASTUS, Juss. 
Spikelets terete-compressed, nearly sessile, panicled, with 
several empty glumes in the lower part, 1 fertile glume, and 
a terminal pedicellate rudiment. Outer glumes 2, short,
