CLVII. GRAMINEiE (Stapf). 
451 
spreading fringe ; valvule and lodicules minute. Upper floret 
broad-lanceolate, acute, early brown, at length almost black, shining, 
chartaceous to subcoriaceous, finely punctate-striate. Anthers 
oblong, about J-J or f {Barter, 1370) lin. long, with papillose bases. 
Grain elliptic-oblong, plano-convex, ~ lin. by J lin., white ; scu- 
tellum elliptic, equalling half the grain. — P. sanguinale , var. Lecardii, 
Pilger in Engl. Jahrb. xxx. 118.

Good fodder according to Lecard. 
1 found the anthers of the small type always tightly enclosed in the lloret 
and entangled in the scanty hairs of the stigmas. They bold comparatively 
little, but apparently perfect, pollen. 
20. D. xanthotricha A Staff. Annual, 2-3 ft. high. Culms 
erect or geniculate-ascending, simple or with a branch from the 
base, very slender, 3-4-noded with the uppermost internode by far 
the longest, terete, glabrous. Leaf-sheaths tight, terete, shorter 
than the internodes, glabrous or more or less hirsute with short 
tubercle-based hairs ; ligules very short, truncate, ciliate, brown ; 
blades linear from an equally wide base, long-tapering to an acute 
point, 2-4 in. by 1J-2J lin., thin, glabrous, smooth except at the 
slightly rough cartilaginous margins, nerves numerous, close, midrib 
slender somewhat prominent below, obscure above. Racemes 2, 
one sessile, the other shortly peduncled, or 3-4, sessile, subdigitate, 
slender, 3-7 in. long, dense or somewhat lax ; rhachis filiform, tri- 
quetrous, f-J lin. wide, angles narrowly marginate, scabrid, glabrous, 
internodes about 1| lin. long ; pedicels 2-nate or 3-4-nate, unequal, 
the longest up to 14 lin. long, filiform, compressed, scabrid with a 
short beard of pale green or at length yellowish hairs. Spikelets 
subimbricate or in slightly distant clusters, lanceolate -oblong to 
lanceolate, acute, 1J lin. by f lin. (excluding the apical hairs), pale 
yellowish or tinged with purple. Lower glume suppressed ; upper 
linear-lanceolate, much narrower than the spikelet, acute, slightly 
shorter than the spikelet, membranous, 3-nerved, aj^pressedly and 
densely hairy between the nerves and along the margins, hairs 
rather rigid with sharp points. Lower floret corresponding in out- 
line and size to the spikelet : valve membranous, 3-nerved (or 
the submarginal nerve splitting at the base into 2 strands), with a 
transverse fringe of hairs above the base and a dense marginal one 
on each side, otherwise glabrous or with decurrent lines of hairs' 
below the transverse fringe which thereby becomes less "conspicuous, 
the hairs like those of the upper glume but rather longer (4 lin.), 
at first tightly appressed, ultimately rigidly spreading : valvule 
and lodicules minute. Upper floret ovate-lanceolate, acutely acumi- 
nate, equalling the spikelet ; valve chartaceous, 3-nerved, seriately
