inflexed edges. Ovary glabrous, stipitate. — Nees, L c. p. 

 375. 



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 (as in our Cape species) rarely rigid, and 

 longer than the flowers, pointless, persistent, keeled. Elower- 

 ing glume membranous, 8-nerved, keeled, pointless, or mucro- 

 nate or aristate ; palea shorter, 2-keeled, with a straight, 

 unjointed awn. — Nees, I. 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. — Nees, I. c. p. 254. 



Poa-like grasses, usually with livid or brownish flowers. — 5 Cape species. 



SUBTRIBE 5. AVENACE^. 



53. ANISOPOGON, K. 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 

 segments setaceous, with a very long awn, twisted at base, 

 between the segments ; palea longer, 2-fid. Ovary stipitate. 

 —Nees, I. c. p. 265. 



A. Capensis, Nees, is an oat-like grass, fovmd 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 palea? 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, I. c. p. 9.
