    bulatc-acuminate, the lower smaller 3-nerved, the upper 5- nerved. Lower flower male; its flowering glume like the upper outer glume, subulate-acuminate; its palea 2-parted, membranous, shorter, the segments acuminate, eared in front and clasping the stamens. Upper flower hermaphrodite, the flowering glume and palea subequal, taper-pointed ; the former convex, with an awn-like point; the latter dorsally concave, mucronate, eared on each side at base, the ears clasping the flowers.—Nees, 1. c. p. 61. B. EcMoniana, Nees, is a handsome grass, common to the east of Uiten- hage. 6. SETARIA, Beauv. Spikelets generally swollen on one side, in dense spiked panicles, or apparently cylindrical spikes, 2-flowered, awnless, mth a persistent involucre (abortive branchlets), composed of simple scabrous bristles, principally placed on one side. Outer glumes 2, the lowest very short. Lower flowers male or neuter; upper flowers hermaphrodite; the flowering glumes often mucronate, generally wrinkled on the back, and often marked on each side with a curious horseshoe-shaped impres- sion ; otherwise as in Fanicv/ni.—Panicum, Nees, l.c. p. 52-56 ; Kunth, Env/ni. p. 149. A widely-distributed genus, affording good fodder grasses.—8 species at the Cape. 7. PENICILLARIA, Willd. Spikelets 2-flowered, in a spike-like raceme, each 1-2 spike- lets with an involucre of 2 sorts of bristles ; the outer bristles short, scabrid; the inner longer, mostly plumose towards the base. Outer glumes 2, very short, membranous, nearly nerve- less. Lower flower either neuter and 1-valve or male 2-valved; its flowering glume entire or emarginate. Upper flower hermaphrodite, rarely female ; the flowering glume and palea convolute, papery, either entire, trimcate or 2-fld, hardening in fruit. Anthers bearded at the apex. Grrain enclosed in the flowering glume and palea.—Nees, l.c. p. 71. Usually tall grasses, affording a millet in several species,—P. Plukenetii is in Drege’s collections, and P. spicata in Burchell’s. 8. TRICHOLIENA, Schrad. Spikelets in diffuse panicles, 2-flowered. Outer glumes 2, membranous, softly silky, the lower very small or reduced to a silky ring; upper as long as the loAver flowering glume, mucronate or setigerous below the 2-fid a])ex. Lower flower male or neuter, its flowering glume very like the upper outer
