CXLII. GRAMINEA. 45 
76. POA, Linn. 
Spikelets 2-7-flowered, compressed, panicled. Outer glumes 
keeled, herbaceous, not setigerous, mostly shorter than the 
flowering, the lower 1-3-nerved, the upper 5—7-nerved. Flower- 
ing glumes thinly herbaceous, keeled, persistent, 5-3-nerved, 
the lateral nerves distant, often pubescent; palea 2-toothed, 
flattish, with inflexed edges, 2-nerved, the nerves hispid. 
Ovary glabrous.—Nees, l. c. p. 377. 
A large genus, dispersed over the world.—3 Cape species, one of which, 
P. annua, is a garden weed. é 
77. ERAGROSTIS, Beauv. 
Spikelets 2-many-flowered, more or less strongly com- 
pressed, panicled or rarely subspicate. Outer glumes keeled, 
distichous, pointless, deciduous, 1-nerved, lower smaller. 
Flowering glumes keeled, 3-nerved, deciduous ; palea persis- 
tent, reflexed, the folded margins distinctly nerved, entire, 
more or less ciliate.—Vees, l.¢. p. 382. 
A large genus, in warm countries, chiefly differing from Poa by its flattened 
spikelets and more regularly distichous glumes.—About 30 Cape species. 
78. BRIZA, Linn. 
Spikelets many-flowered, ovate or 4-sided, compressed, 
panicled or racemose. Outer glumes herbaceous, unequal, 
keeled, ventricose, shorter than the spikelet, 5-7-nerved. 
Flowering glumes closely imbricate, cordate, keeled, com- 
pressed, round-topped, entire, pointless, 7-15-nerved ; palea 
much smaller, entire, flat, ovate, 2-nerved. Grain flattened. 
—WNees, l.c. p. 415. 
Of this dispersed genus there are 1 indigenous, perennial, and 2 natural- 
ized, annual Cape species. —B. maxima is found everywhere. 
79, FESTUCA, Linn. 
Spikelets many-flowered, flattened, in panicles. Outer 
glumes unequal, shorter than the spikelet. Flowering glumes 
imbricated, keeled toward the apex, mucronate or tapering 
into a bristle; palea 2-dentate, with inflexed sides. Grain 
tomentose or glabrous at the apex.—WNees, l.c. p. 442, and 
p. 440, sub Vulpia. 
A large, widely-diffused genus, many of them pasture grasses.—7 Cape 
species. 
nee the subgenus Vulpia, one of the lower glumes is occasionally extremely 
short, and the flowering glume is often very long-pointed.
