plant, about }’’ long, obovate, very pubescent, first scale 
about one-third as lone as the 7-nerved second and third. 
Peduncle twice the length of panicle. 
Dry sandy fields, New Jersey to Georgia near the coast. Related to PP 
viscidum. Description based on plants growing at Chapel Hill, N. C.

Div. of Agrost. 43 (1898). Culms erect, tufted, 12’—20” 
high, very slender, somewhat geniculate at the nodes. 
Stem, to base of panicle, more or less pubescent with 
short white hairs, barbed above the naked ring at the 
joints. Sheaths about one-half the length of the inter- 
nodes, more or less hirsute, at least below ; ligule a ring 
of hairs 2” long. Stem leaves ascending, linear-lanceo- 
late, gradually narrowed to the base, 2’—3’ long, about 
3’? wide. 7—9-nerved, more or less pubescent; basal 
leaves much shorter, nearly glabrous. Panicle 1’ or more 
long, about as wide, the numerous slender branches 
spreading ; spikelets obovate, apiculate, 5 —%’’ long, 
first scale minute, one-fourth as long as the nearly glab- 
rous, 7-nerved second and third. Color of piant green, 
often purplish. Late stages much branched above. 
Northeastern States. Specimens examined : New Jersey; Com- 
mons, 1897. New York : Wiegand, Ithaca, 1893. New York: Ashe; 
Watkins, June, 1898. New York: Ashe; Courtland, Aug. 1898. 
Maine; Merrill, 1897. Its smaller leaves, more branched panicle, and 
smaller spikelets separate this plant from /. pubescens to which it is 
most closely related.

ule very short, pubescent. Leaves lanceolate, 3’—4’ long,
