ele, at first simple and erect, later much branched, 
spreading or reclining, glabrous, or below somewhat 
pubescent. Sheaths shorter than the internodes, the 
lowest generally pubescent, the upper smooth. Primary 
leaves erect, flat, glabrous, linear-lanceolate, the largest 
3°—4’ long, 2’’—23”’ wide, narrowed at the base, secon- 
dary leaves much smaller and crowded at the top of the 
ascending or reclining branches. Primary panicle ob- 
long, 3’—4’ long, glabrous, the branches at first erect, 
at length spreading, the flowers on long flexuous pedicels, 
spikelets 1°’ long, or over, elliptic, acute, abruptly con- 
tracted at the base.

(1897). Culms tufted erect. slender. smooth above, pub- 
erulent below, a foot or more tall. Sheaths often longer 
than the internodes, the lower pubescent with the nodes 
bearded ; ligule pubescent. Stem leaves linear-lanceo- 
late, narrowed at the ciliate base, otherwise smooth, the 
largest 5’—8’ long, 4’’—5"’ wide, the upper ones longest. 
Panicle 2?—4 long, with ascending, flexnous branches; 
spikelets obtuse, oval or obovate, about 15’’ long, second 
and third scales 9-nerved. Secondary panicles much 
smaller, on erect branches, and not basal as in P. depau- 
peratum. 
This species has the habit and appearance of P. depauperatum, from 
which it is separated by having much broader leaves and smaller 
spikelets. New York, Pennsylvania and New Jersey. Porter; Penn-
