the base, quite glabrous, usually slender, from under 1 ft. to abov 
ft. high, but exceedingly variable in stature and aspect. Leaves from 
very narrow to rather broad. Panicle usually long and slender, the 
branches or sessile spikes or clusters erect, distant, the lower ones 3 to 
4 lines or rarely 3 to 1 in. long, the upper ones smaller, often reduced 
to short clusters or to single spikelets towards the end of the panicle, 
the rhachis of the branches often but not always produeed beyond the 
last spikelet into a point sometimes as long as the spikelet. Spikelets 
singly sessile or in pairs, one pedicellate the other sessile along the 
rhaehis, rarely more or less distinctly in 2 rows almost as in P. flavi-
