below. Lower floret g, very similar to the upper glume, but not 
mucronate nor with the nerves joining, although converging ; valvule 
somewhat shorter, sharply keeled, with the flaps widening from the 
tips downwards. Upper floret very broadly elliptic, obtuse, 
with narrow involute margins, § lin. long, brownish, polished.

Hist. Nat. Autun, viii. 342 (reprint 34). Annual, tufted, J-3 ft. high. 
Culms erect or geniculate-suber'ect, usually branched all along or 
upwards with the branches erect, usually about 6-noded, terete, 
slender, densely hirsute to almost glabrous, internodes mostly at 
length bared by the slipping off of the sheaths. Leaf-sheaths at 
first tight, then loosened, somewhat firm, strongly and closely striate, 
more or less hirsute, sometimes densely so, hairs spreading from small 
persistent tubercles ; ligule a densely ciliate rim ; blades narrowly 
linear from an equally wide base, tapering to a slender point, J to 
over 1 ft. long, 1-2 lin. wide, flat or convolute and flexuous, finely 
hirsute, mainly from the midrib and primary nerves, these 2-3 on 
each side, like the midrib very slender, somewhat prominent below, 
hardly differentiated above. Panicles terminal and axillary, oblong 
to obovate, contracted or open, flexuous or slightly stiff, 3-9 in. long, 
when opened out up to 4 in. wide and very loose, divided to the third 
or fourth degree, all divisions very slender to finely filiform, obliquely 
spreading when mature (see note below), upwards sharply angular 
and scabrid, all over loosely to very loosely and finely hirsute ; 
primary branches irregularly scattered, often approximate in pairs 
or false whorls, with obscure motile cushions at the base, divided 
from the base or some distance (a few to 9 lin.) above it, the longest 
2-5 in. long, divisions remotely divided again twice (below with 2 
rarely 3 spikelets) or once, 8-2-spiculate ; pedicels hardly widened at 
all upwards, the lateral 1-3 lin. long. Spikelets oblong, acutely 
acuminate, early gaping, sometimes widely so, slightly over 1 lin. 
long, pale greenish or brownish with darker tips, stiffly hairy. Glumes 
obliquely spreading to subdivaricate, very similar, obliquely lanceo- 
late in profile, thinly membranous, finely and slightly prominently 
nerved ; lower rather narrower and more finely acuminate, usually 
mucronate, three-quarters to over four-fifths the length of the upper, 
5-nerved, upper 5-7-nerved. Lower floret : valve similar to the 
upper glume but slightly shorter, less or obscurely acuminate, 
5-nerved, outer nerves very faint ; valvule lanceolate-oblong, 
slightly shorter, acuminate, flaps wide below ; anthers J lin. long. 
Upper floret oblong, about § lin. by not quite J lin., whitish, 
smooth, slightly glossy. — r Th. & Hel. Durand, Syll. FI. Congol. 632 ;
