[ Urochloa . 
scabrid ; pedicels very short, stout, shortly and densely hairy. 
Spikelets rather small, up to 20 per raceme, imbricate, lanceolate, 
acuminate, dull green. Glumes dissimilar ; lower rotundate or 
shortly acute, almost one-third the length of the spikelet, hairy on 
the back ; upper much narrower than the spikelet, acute, prominently 
nerved, densely hairy. Lower floret : valve with a long white 
silky dense marginal fringe. Upper floret rotundate- elliptic in 
outline, pale yellowish, chartaceous, transversely rugulose ; valve 
with a setiform mucro. 
Mozambique Distr. Italian Somaliland : abundant in the plain of Merca , 
Maculoso, 10. 
Undoubtedly a species of TJrochloa, but I cannot place it owing to the incom- 
pleteness of the description. 
68. ECHIN0CHL0A, Beauv. Agrost. 53, t. 11, fig. 2. 
Spikelets ovate to elliptic- or lanceolate-oblong, usually cuspidate 
or awned, very convex on the back, flat or slightly depressed in 
front, falling entire from the pedicels, 2-nate or clustered, secund 
and abaxial on the triquetrous rhachis of racemosely arranged false 
spikes ; lower floret $ or barren, upper floret Glumes unequal, 
membranous, the lower much shorter, more or less ovate from a 
clasping base, 3-5-nerved, often mucronate, the upper corresponding- 
in length and outline to the spikelet (as seen from the back), very 
concave, 5-7-nerved, acute, cuspidulate or cuspidate, rarely pro- 
duced into a short awn. Lower floret equalling the upper glume 
(excluding cusps or awns) : valve very similar to the upper glume, 
but flat or depressed on the back and often with a more pronounced 
cusp or an awn ; valvule equal to the body of the valve, or in barren 
florets more or less reduced, hyaline, finely 2-keeled. Upper floret : 
valve ovate to elliptic-oblong, apiculate or obtuse, very convex on 
the back, subcoriaceous or crustaceous, polished, faintly 5-nerved, 
margins firm, involute up to near the tip, then flat, not embracing 
the tip of the valvule ; valvule subequal to the valve and similar 
in substance, with rounded keels and flaps which thin out towards 
the flat slightly recurved tips. Lodicules 2, cuneate, fleshy. Stamens 
3. Styles distinct ; stigmas plumose, exserted from near the tips. 
Grain broad-elliptic, dorsally flat, ventrally convex ; hilum puncti- 
form, subbasal. Embryo elliptic- oblong or ovate, exceeding the 
middle of the grain. — Perennial and often tall, or annual ; blades 
linear from a slightly constricted or equally wide rarely much 
attenuated base ; ligules 0 or represented by a transverse fringe of 
hairs ; panicles of crowded or loosely arranged secund spiciform 
branches mostly bearing spikelets from the base or near it ; spikelets 
more or less hispid on the nerves of the glumes, and the lower valve, 
rarely almost smooth.
