from the base ; secondary branchlets mostly 1J-2 lin. distant, np 
to 6 lin. long, but mostly much shorter, again divided from the base ; 
pedicels capillary, very unequal, from very short to over 2 lin. long, 
with obscurely widened tips. Spikelets lanceolate, acuminate, 
1 lin. long, pale greyish-green, very finely pubescent from the glumes 
and the lower valve. Glumes very thinly membranous, very finely 
nerved ; lower ovate, acute or subacuminate, up to half the length 
of the spikelet, 1 -nerved, almost hyaline ; upper corresponding to the 
spikelet in length and outline, 3-5-nerved. Lower floret reduced to the 
valve which is very similar to the upper glume but 3-nerved. Upper 
floret lanceolate-oblong, acute, § lin. long, turning brown, polished.

86. P. trichoides, Sw. Prodr. Veg. Ind. Occ. 24. Annual, loosely 
tufted, from a few inches to 1 J ft. high. Culms very slender to filiform 
from an ascending base, up to 9- or more-noded, terete, glabrous or 
more or less finely pubescent, lower internodes short, those of the 
upright part few and long (the uppermost up to over 6 in.) and long- 
exserted. Leaf-sheaths thin, the lower loose and short (3-4 lin. 
long), the upper tight and long, prominently striate, spreadingly 
hirsute with tubercle-based hairs ; ligule a very narrow mem- 
branous ciliolate rim ; blades narrowly lanceolate, from a rounded 
much constricted base, finely acuminate, from less than 1 (lower 
leaves) to 3 in. by 3-4 lin., flat, very thin, flaccid, sparingly and finely 
hairy, margins scaberulous, midrib and primary nerves (about 3 on 
each side) very fine, secondary nerves about 5 in each interval with 
obscure extremely delicate cross-veins. Panicles erect, long- 
exserted, ultimately somewhat stiff, widely open and very loose and 
delicate, ovate-oblong in outline, up to 9 in. by 6-8 in., divided to the 
third degree ; axis very slender, terete or angular, smooth below, 
scaberulous upwards, internodes •§— f in. long, sometimes with a few 
longer ones thrown in ; primary branches finely filiform, ultimately 
much spreading, smooth like all the following divisions, and like 
these very loosely divided from the base, the longest up to 4 in. long ; 
secondary branchlets finely capillary, up to 8 lin. long, bearing 3-1 
very widely scattered spikelets ; pedicels extremely delicate, but 
straight, 3-8 lin. long, not thickened upwards. Spikelets elliptic- 
oblong, obtuse, very slightly over J lin. long, hardly oblique in profile, 
greenish, finely puberulous. Glumes very thinly herbaceous, very 
faintly nerved ; lower broad-ovate from a clasping base, acute, 
3- to sub-5-nerved, upper corresponding to the spikelet in length and 
outline, 5-nerved, broad on the back. Lower floret barren ; valve 
very like the upper glume ; valvule reduced to a hyaline oblong scale. 
Upper floret Q elliptic in outline, acute, less than \ lin. long, whitish 
or yellowish, smooth, but not polished ; valve and valvule papery. —
