    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 3-11-nerved. Lloweriug glumes convex and moderately keeled, under the 2-dentate apex seti- gerous or entire and ]mintless, with 7 primaryhierves; palea infolded, entire or 2-fid. Ovary pubescent at the apex. Grain mostly attached to the palea.—Nees, l.c. p. 450. A large, widely-spread genus.—6 Cape speeies. 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).—Nees, 1. c. p. 449. C. unioloides, an American grass, is naturalized about Capetown. 82. CYNOSURUS, 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, mucrouate or awned ; palea membranous, 2-nerved, folded, 2-toothed. Grain glabrous, adherent.—Nees, 1. c. p. 439. Rigid, narrow-leaved grasses.—2 Capo species; one scai'cely different from C. echinatus, Linn. 83. EHRHARTA, Thunb. Spikelets 1-flowered, compressed, pauicled. 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.—Nees, l.c. p. 196. A large genus, containing 2't Cape species, of very elegant grasses ; the 2 inner empty glumes often ribbed and furrowed crosswise. An interesting link between ordinary Festucacem and Bamlusecs. StTBTEIBE 7. BAMBtrSEiE. 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.
