pointed, villous to sparingly hirsute, 7--9-nerved, the 
longest about 3’ long and 3”’ wide; upper leaves much re- 
duced in size; basal leaves hirsute, shorter and broader. 
Panicle about 2inches long, nearly as broad, the branches 
single or in pairs, spreading or ascending; spikelets 
somewhat obovate, obtuse, scarcely 1”’ long, first scale 
one third the length of the pubescent, 7-nerved second 
and third; peduncled 2 to 3 times the length of panicle. 
The late form densely fasciculately branched and spread-

60) Panicum CoMMONSIANUM Ashe, sp. nov. Stems 
clustered, erect, strict, 8’—16’ high, below appressed 
pubescent, above ¢labrous or puberulent. Sheaths short- 
er than the leaves or the lower overlapping, the lower 
appressed pubescent with ascending hairs, the nodes 
densely barbed with short ascending hairs. Leaves glab- 
rous, or sparingly ciliate near the base eréct or ascend- 
ing, narrowly lanceolate, gradually narrowed to the apex 
from near the base; 14’—2’ long, ligule pilose. Panicle 
11’ —3’ long, as broad as long, the branches fascicled, 
spreading, long-peduncled, glabrous or the axis puberu- 
lent; spikelets 1’’ long, obovate, or broadly elliptical, pu-

Based on No. 341, Commons. Collected in drifting sands along the
