crowded above, about 1’ long, spreading, much longer than 
the very numerous, short, secondary panicles. Primary 
panicles short-peduncled, 1’—2’ in length, oval, the 
spreading branches mostly single, rather few flowered, 
the slender peduncles two to many times the length of 
the obovate, pubescent, %” long spikelets.

(1897). Culms tufted, erect or ascending from a usually 
geniculate base, 10’—20’ high. Stem more or less pilose 
with spreading or ascending hairs, the nodes long-barbed 
above the naked ring. Sheaths pilose to villous, gener- 
ally papillate, the lowest nearly as long as the inter- 
odes, the upper much shorter; ligule pilose, hairs 2”—3” 
long. Stem leaves ascending, above smoothish, below 
generally villous, the margins often ciliate with long 
hairs, 2’—3’ long, 2”—3” wide, linear-lanceolate; narrow- 
ed at the somewhat rounded base, taper-pointed, middle 
leaves the longest; basal leaves much shorter; the later 
leaves on the secondary branches, ascending, one-half the 
length of the primary,smooth.’ Panicle 2—3’ long, nearly 
as wide, long-peduncled, the branches somewhat ascend- 
ing, spikelets rather numerous, obovate, acute, quite 1” 
long, the first scale full one-third as long as the minutely 
pubescent 9-nerved second and third; later panicles not 
expanding, one-half the length of the surrounding leaves.

57) PANICUM SCOPARIOIDE Ashe. sp. nov. Stems sin- 
ole or a few together, erect, columnar, 16’—20’ high, 
appressed pubescent. Sheaths papillose-pubescent, with 
ascending or appressed hairs, the lower much shorter 
than the internodes, the upper longer ; ligule pilose.
