inflexed edges. Ovary glabrous, stipitate-—Mees, l.c. p.

T. Dregei, Nees, an Eastern district grass, is the only species. 
51. LEPTOCHLOA, Beauv. 
Spikelets 2—-several-flowered, sessile, unilateral, in racemose 
spikes. Outer glumes 2, keeled, membranous, either shorter 
than the flowering or (asin our Cape species) rarely rigid, and 
longer than the flowers, pointless, persistent, keeled. Flower- 
ing glume membranous, 3-nerved, keeled, pointless, or mucro- 
nate or aristate; palea shorter, 2-keeled, with a straight, 
unjointed awn.— Nees, 1. c. p. 252. 
L. grandiglumis, Nees, is the only Cape species. 
52. DIPLACHNE, Beauv. 
Spikelets several-flowered, in compound racemes. Outer 
glumes unequal, the upper mucronate. Flowering glume 3- 
nerved, at the sides more or less silky or pubescent, 2-fid at 
apex, setigerous between the lobes.—Wees, l. ¢. p. 254. . 
Poa-like grasses, usually with livid or brownish flowers.—5 Cape species. 
SUBTRIBE 5. AVENACER. 
53. ANISOPOGON, Rh. Br. 
Spikelets loosely panicled, with 1 fertile, pedicellate flower- 
ing glume and a rudimentary one. Outer glumes 2, membra- 
nous, subequal, 3- or several-nerved, longer than the flowers. 
Flowering glume subcoriaceous, oblong, convolute, 2-fid, the 
seoments setaceous, with a very long awn, twisted at base, 
between the segments; palea longer, 2-fid. Ovary stipitate. 
—WNees, l.c. p. 265. 
A. Capensis, Nees, is an oat-like grass, found near Tulbagh. 
54. HOLCUS, Linn. 
Spikelets in a branching panicle, 2-flowered, the flowering 
glumes subdistant, the lower hermaphrodite, pointless, upper 
awned, often only male, or in the Cape species neuter. Outer 
glumes membranous, keeled, longer than the flowers. Flower- 
ing glumes and pales membranous, of about equal length, the 
former keeled, the lower awnless, the upper, which is 2-keeled, 
awned below the tip. Grain glabrous, free.— Nees, l. c. p. 9.
