[Sacciolepis. 
tubercle-based finally deciduous hairs, the others quite glabrous and 
smooth ; ligule a fine membranous rim ; blades linear-lanceolate 
(lower) to linear from a slightly narrowed base, tapering to a sub- 
callous point, 2 in. by 3 lin. (lower) to 5 by 2 lin., flat or more or less 
folded or convolute upwards, green, loosely hairy on both sides with 
the hairs deciduous leaving small tubercles behind, margins scaberu- 
lous, midrib very slender, whitish and prominent below, primary 
lateral nerves 2-3 on each side, distinct below. False spike erect on 
a long-exserted peduncle, less than 1 in. by over 3 lin., rather loose ; 
axis very slender ; pedicels in small clusters or solitary from the axis, 
very short, somewhat stout, smooth with discoid tips. Spikelets 
ovate-oblong, mostly slightly oblique, acute to subobtuse, 2 lin. by 
J lin., quite glabrous and smooth, whitish. Glumes firmly mem- 
branous, nervation evanescent downwards or altogether obscure ; 
lower broad-ovate from a clasping base, obtuse, over half the length 
of the spikelet ; upper very concave, with a back more curved than 
that of the lower floret, 9-1-nerved. Lower floret barren : valve 
very similar to the upper glume and of equal length, but the tip more 
obtuse when flattened out, 9-nerved with a marked “ window ” on 
each side at the base ; valvule narrow, half the length of the valve, 
narrow. Upper floret oblong, obtuse, 1J lin. by 4 lin., whitish, 
polished.

21. S. curvata; Chase in Proc. Biol. Soc. Wash. xxi. 8. Perennial, 
from a very slender early disintegrating rhizome, 1 to several ft. 
high. Culms very slender, weak, geniculately ascending from an 
often decumbent base, branched below, the upright parts 4-7 -noded, 
terete, quite glabrous and smooth, internodes mostly exserted. Leaf- 
sheaths rather tight, the lowest at length drying and breaking up, 
all quite glabrous and smooth or finely ciliolate along the outer 
margin, striate ; ligule reduced to a very obscure minutely ciliolate 
rim ; blades lanceolate-linear to linear from a shortly constricted 
base, tapering to an acute point, 2 to over 3 in. by 2-3 J lin., flat, 
thin, glabrous and smooth except along the finely scaberulous 
margins ; midrib very fine, somewhat prominent below, primary 
lateral nerves 2-3 on each side, faint. Panicle erect, at length mostly 
long-exserted, ovate to ovate-oblong in outline when open, 1J-44 in. 
long, divided to the third or sometimes fourth degree ; common axis 
slender, striate to subangular, like all its divisions more or less wavy, 
terete and smooth, lowest internodes from over 1— J in. long, the 
upper relatively numerous and short ; primary branches solitary, 
rarely approximate in pairs, subcapillary to capillary, divided from 
the base, the lowest up to half the length of the panicle, often spread- 
ing at angles of 50°-90° ; secondary branchlets forming more or 
less secund simple or downwards compound loose racemes of 2-7
