[Sacciolepis. 
Leaf-blades filiform-convolute, up to 1 ft. 
by £-f lin. in diam. (1-1| lin. when 
flattened out); spikelets 1 lin. long ll.[S. scirpoides. 
Axis of false spikes slender, hardly rigid ; 
basal sheaths short or if long (13, 
8. ty'phura ) then not spongy, but rather 
firm and closely nerved ; spikelets hairy 
(except 12, 8. glaucescens). 
Spikelets without a transverse fringe of 
hairs, in dense spikes ; upper glume 
and lower valve 7-9-nerved. 
Spikelets quite glabrous, obtuse or sub- 
acute to acute owing to the inrolling 
of the hyaline tips of the upper 
glume and lower valve ; leaves glau- 
cous ; basal sheaths short, wide, 
more or less spongy ; blades mostly 
convolute, rigid, up to 6 in. long ... 12.'#. glaucescens. 
Spikelets more or less hairy, very dark. 
Culms rigidly erect, simple ; leaf- 
blades more or less rigid, 6-12 in. 
by l|-5 lin. ; false spikes 3-10 in. 
by 3 lin. ... ... ... ... 13. 8. ty'phura. 
Culms very slender, ascending in wide 
curves like their remote branches ; 
leaf -blades soon flaccid, 3-6 in. by 
1| lin. (flat) ; spikes f-lj in. by 
2-2| lin 14. 8. incurva. 
Spikelets with a transverse fringe of 
silvery hairs ; false spikes lobed or 
much interrupted or very scanty, 
1^ in. by 2\ lin. ; upper glume 13- 
nerved; lower valve 11 -nerved ... 15. 8. transbarbata. 
Spikelets 2-2 1 lin. long, or if 1£ lin. long then 
the sheaths auricled at the mouth ; glumes 
(or at least the upper) rigidly or firmly 
membranous, glabrous, rarely hairy (some- 
times in 16, 8. auriculata), nerves rather 
rib-like, sometimes evanescent downwards. 
Leaf-sheaths auricled at the mouth ; culms 
collapsing when dried, ascending from a 
decumbent and rambling base with long 
aerial roots from the nodes ; blades up to 
over 6 in. by 1 J-2 lin., flexuous ; spikes 
1-6 in. by 3-3J lin. ; spikelets pale, 
glabrous or hairy .. . ... ... ... 16. S. auriculata. 
Leaf-sheaths not or obscurely auricled (17, 
8. leptorrhachis) ; spikes rather short, 
rarely over 3 in. long. 
Nervation of glumes and lower valve dis- 
tinct ; spikelets yellowish or olive- 
green, darker upwards. 
Culm-bases hardly wiry, the culms above 
it up to 5- or more-noded, collapsing 
when dried ; sheaths with obscure 
auricles or shoulders ; false spikes 
up to 4 in. long, continuous or irregu- 
larly interrupted ; spikelets ovate- 
lanceolate, more or less oblique ... 17, S . leptorrhachis
