15. S. scintillans, Stapf. Annual. Culms very slender, scantily 
fascicled, about 1 ft. high, slightly compressed below, terete upwards, 
smooth, glabrous, few- to 6-noded, with the nodes exserted, branched 
from the lowest or intermediate nodes upwards, all branches flower- 
ing, solitary or 2-nate. Leaf-sheaths glabrous, the lowest com- 
pressed and keeled, the others terete, tight ; ligules membranous, 
truncate, short ; blades narrowly linear to filiform, tapering to a 
fine point, up to 2 in. by f lin., soft, with scattered long very fine 
hairs, midrib very fine, primary lateral nerves 1 on each side ; spathes 
very narrow with a setiform scaberulous blade, 1-4 lin. long. 
Racemes on filiform, more or less flexuous glabrous peduncles which 
are slightly thickened at the tips for 1-2 lin. and terminated by a 
small cupular appendage, at length more or less (by up to J- in.) 
exserted from the spathe, f-1 in. long, pale brown, marked with 
patches of brilliantly silvery hairs, 4-6-noded ; joints cuneate- 
subulate, slightly curved, 1J lin. long, with a minute cupular entire- 
rimmed appendage, minutely granular on the back, shortly and very 
densely ciliate on the inner edge up to about two-thirds of its length 
and longer-ciliate on the outer edge from the middle upwards, 
cilia like all the hairs of the inflorescence glistening, silvery ; pedicels 
very similar, but shorter, with a 2-dentate appendage. Sessile spikelet 
lanceolate, acuminate, about 2J lin. long, with a minute shortly 
bearded callus. Glumes unequal ; lower almost flat on the back, 
2-mucronulate, with narrow sharply inflexed margins, thinly char- 
taceous, with distinct or more or less obliterated longitudinal lines 
of short hairs on the back, keels obscurely scaberulous, intracarinal 
nerves 3, faint ; upper glume dorsally compressed, shorter than the 
lower, oblong, shortly acute, membranous below, white-hyaline 
upwards, 1-nerved, often finely mucronate, ciliolate upwards. 
Lower floret reduced to an oblong truncate or 2-dentate valve, 1| lin. 
long, hyaline, ciliolate, finely 2-nerved. Upper floret $ : valve 
linear, stipitiform, 1J lin. long, white, hardened upwards and passing 
rather abruptly into the awn, 3-nerved, lateral nerves very indis- 
tinct ; a wn about 6-8 lin. long, kneed and twisted below the middle,
