2, membranous, equal, longer than the flower. Flowerin 
glume on a hard, raised point, papery, convolute, 2-lobed, be- 
tween the lobes bearing a jointed, 3-fid awn; palea short, 
obtuse.—WVees, l. c. p. 171. 
3 Cape species. Genus scarcely distinct from the following. 
38. ARISTIDA, Linn. 
Spikelets panicled or subracemose, 1-flowered, the flowering 
glume stipitate. Outer glumes 2, membranous, unequal, mostly 
pointless, the lower shorter. Flowering glume hard, conyo- 
lute, awned at the apex, the awn 3-partite or 3-fid, with or 
without a joint at base. Palea minute. Grain terete, en- 
closed in the flowering glume.—Kwunth, Enum. l.c. p. 187. 
Arthratherum and Chetaria, Nees, 1. c. pp. 174, 186. 
A widely-dispersed genus, containing about 15 Cape species.—The awn 
is jointed and caducous in Arthratherum; unjointed and persistent in 
Chetaria, 
SUBTRIBE 3. ORYZER. 
39. LEERSIA, Soland. 
Spikelets 1-flowered, compressed, racemoso - paniculate. 
Outer empty glumes 0. Flowering glume and palea herba- 
ceous, rigid, compressed, keeled, pointless, closed, about equal 
in length. Stamens 1-3-6. Grain compressed, free, covered 
by the valves.— ees, 1. ¢. p. 193. 
L. Mexicana is found in Uitenhage. Stamens 6 in this species. 
40. MALTEBRUNIA, Kunth. 
Spikelets 1-flowered, panicled. Outer glumes 2, small, 
membranous, channelled and keeled, pointless. Flowering 
glume and palea membranous, boat-like, subequal, compressed, 
the glume much the wider, pointless. Stamens 6— lees, /. c. 
p. 194. 
M. prehensilis, found by Drége, is unknown to me. Culm much 
branched ; leaves subsessile, hairy on the margin and keel armed with 
recurved, minute prickles. 
SUBTRIBE 4. CHLORIDE. 
41. MICROCHLOA, R. Br. 
Spikelets 1-flowered, unilateral, in solitary spikes. Outer 
glumes 2, oblong, subacute, subequal, membranous, pointless, 
the lower 3-nerved, keeled. Flowering glume and palea 
shorter than the outer glumes, thinly membranous, transpa-
