primary branches 1- 2 in. long, divided from low down (occasionally 
undivided for J-l in.), the following from the base, very finely 
filiform to subcapillary, smooth ; ultimate divisions capillary, wavy ; 
pedicels unequal, the lateral 1-2 lin. long, the terminal slightly longer, 
with minute discoid tips. Spikelets ovate-elliptic, acute to subacute, 
1 lin. long, dull, pale green or slightly tinged with brown, glabrous. 
Glumes very thinly membranous, faintly nerved, rather concave, 
obliquely oblong to (the lower) lanceolate in profile, the lower over 
three-quarters the length of the spikelet, 3-nerved, the upper sub- 
equal to the spikelet, 5-nerved. Lower floret $ : valve very like 
the upper glume but less acute, 5-nerved ; valvule slightly shorter. 
Upper floret elliptic, subobtuse, § lin. long ; valve and valvule 
thinly papery, verruculose, turning fuscous when mature, with the 
warts showing like white pearls ; anthers § lin. long. Grain pale 
brown, £ lin. by \ lin. ; embryo much less than half the length of the 
grain.

25. P. lindleyanum, Nees ex Steud. Syn. PI. Glum. i. 91. Annual, 
from a few inches to over 3 ft. high, in scanty tufts. Culms erect, 
branched below, all the branches (which are mostly short) flowering, 
slender, terete, 3-7-noded, in tall specimens the upper internodes 
very long and long-exserted, glabrous. Leaf-sheaths tight or the 
lower loose, terete to subterete, glabrous, prominently striate ; 
ligules hyaline, truncate, up to J lin. long ; blades linear from an 
equally wide bas'e, tapering to an acute point, 1-2 J in. by f-lj lin., 
flat, flaccid, green, loosely and often sparingly hairy, more or less 
rough above and along the margins, midrib very slender, but quite 
distinct below, whitish, raised, primary lateral nerves very fine, 
2 on each side below, not differentiated above. Panicle erect, 
obovate to ovate in outline, open and loose, up to over 3 in. by 2 in., 
divided to the third or fourth degree ; common axis filiform, terete, 
smooth, lowest internodes J-J in. long ; lower and intermediate 
primary branches divided from the base or very near it, but very 
rarely forming false whorls, finely filiform, obliquely erect, flexuous 
or rather stiff, scaberulous, the longest about two-thirds the length 
of the panicle ; ultimate divisions capillary, obliquely spreading, 
more or less flexuous ; pedicels unequal, 1-3 lin. long, smooth 
upwards, tips minutely discoid. Spikelets broad- or rotundate- 
elliptic in outline, subacute, f-f lin. long, pale green, more or less 
shortly pubescent. Glumes very thin, similar, obliquely ovate or 
ovate-oblong in profile, mostly unequal, almost as long as the spikelet, 
or the lower slightly but distinctly shorter, subacute, 3- and 5-nerved 
respectively. Lower floret ; valve very similar to the upper 
glume but glabrous ; valvule slightly shorter ; anthers \ mm. long.
