erect, longest towards top of culm, 3’ te 8’ long, 13’’—2”’ 
wide, smocth or hirsute,.sometimes involute; basal leaves 
‘similar to those of the stem’ but shorter. Panicle loose, 
3’—5’ long, branches erect or astending, mostly single, 
flexuous, few-flowered, pedicels mostly very long ; spike- 
lets i}’’—23” long. broadly elliptical or obovate, acute,

30) . PANICUM LINEARIFOLIUM Scribn. Bul. 11, U.S. 
Div. of Avrost. 42 (1898). Densely tufted, 8’—14’ high, 
stems erect, smooth. Sheaths somewhat shorter than 
the internodes, usually hirsute; ligule hairy. Leaves 
linear—lanceolate, erect, firm, 2’—6’ long, 13’’—2°’ wide, 
the base barely narrowed, glabrous above, or with a few 
loug hairs. below appressed pubescent. Primary pazicle 
open, 2’—# jong, the mostly single branches ascending, 
the rather few spikelets borne on pedicels two to many 
times their length. Spikelets elliptical, obtuse, 1’’ or 
slightly more long, very strongly 7-uerved. Secondary 
panicles crowded at base of the culms. 
Maine and New Jersey to Minnesota and Missouri. Distinguished 
from /. depauperatum by having inore slender, obtuse spikelets ; 
while its somewhat longer, more elliptical spikelets, its pubescence 
and the basal panicles separate it from 7. Wernert. Minnnesota ;
