41. D. nitens, Rendle in Cat. Afr. PI. Welw. ii. 165. Perennial, 
compactly csespitose. Culms erect, simple, up to 2 ft. high, slender, 
surrounded. at the base by a dense mass of yellowish matted wool, 
pierced by the rigid fibres of decayed sheaths, 2-3-noded, glabrous 
and very smooth. Leaf -sheaths somewhat loose, glabrous and smooth, 
rarely the lowest of the culms shortly hairy at the nodes ; ligules 
membranous, short, truncate ; blades erect, narrowly linear, taper- 
ing to a sharp point, 3-6 in. by 1-1 J lin., flat, rigid, glabrous or very 
finely hairy, margins scaberulous, midrib and primary side -nerves 
alike, about 7, somewhat stout and more or less prominent. 
Racemes peduncled, gathered into an oblong panicle which is 5-7 in. 
long, loose, flexuous, up to more than 2J in. long, simple or sometimes 
compound low down with short secondary branchlets ; peduncle 
up to over 1 in. long, filiform, terete, smooth, purplish ; rhachis 
filiform, about lin. wide, trigonous, slightly scaberulous along 
the finely marginate angles, internodes 1J lin. long ; pedicels 2-nate 
or upwards solitary, filiform, angular, scabrid and minutely hispidu- 
lous towards the tips, with a subdiscoid tip, up to 1 \ lin. long. Spike- 
lets oblong-lanceolate, acute to acuminate, If lin. long, pale, slightly 
silky. Lower glume 0 ; upper narrowly lanceolate, slightly gibbous 
at the base, acute, f to over 1 lin. long, very thin, very finely sub- 
5-nerved (the outer lateral nerves short and very close to the inner), 
stiffly hairy all over, and so densely near the base that the spikelets 
there appear shortly bearded . Lower floret corresponding in outline 
and size to the spikelet : valve very thin, finely 7-nerved, lateral nerves 
approximate, with dense lines of short (J-J lin.) stiff acute appressed 
hairs between the inner side-nerves and along the margins ; valvule 
and iodicules minute. Upper floret lanceolate-oblong, acutely 
acuminate, very slightly shorter than the barren floret, whitish,- 
very thinly, chartaceous. Anthers almost 1 lin. long. — Panicum
