4iOij CXLII. GRAMINEiE. 



SO. BROMUS, Linn. 



Spikelets many-flowcrcd, in loose ])anicle.s. Outer glumes 

 membranous, unequal, pointless, shorter than the flowering, the 

 lower 1-7-nerved, the upper 3-11-nerved. Flowering glumes 

 eonvex and moderately keeled, under the 2-dentate apex seti- 

 gerous or entire and pointless, with 7 primary nerves ; palea 

 infolded, entire or 2-iid. Ovary pubescent at the apex. Grraiu 

 mostly attached to the palea. — A^ees, I.e. 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 " (Nees). — ]}^ees, I. c. p. 449. 



C. unioloideSy an American grass, is naturalized about Capetown. 



82. CYNOSUIIUS, Linn. 



Spikelets in spike-like, secund panicles, 2-5-flow^ered, inter- 

 mixed witb 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. G-rain 

 glabrous, adherent. — JS^ees, I. 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. Grrain covered by the flowering glume and palea. — J}^ees, 



ic.p.im. 



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 Festucacece and Bamhusece, 



Sttbtribe 7. Bambuse^. 



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,
