glabrous; ligule a mere margin. Leaves 4’—6’ long, 
'3’’°—4”’ wide, oblong-lanceolate, glabrous, abruptly acu- 
minate. Panicle 2’—3’ long,oval, branches spreading, rath- 
er many-flowered; spikelets elliptical to obovate, 13’’ long; 
first scale acute, fully one-half as long as the pubescent 
9-nerved secondand third, fourth scale acute. 
Related to P. Ashei, but the leaves are much longer than? those of 
that plant, while the spikelets areas long asin P. Porterianum. Flor-

single or a few together from a short  root-stock, 
very slender, glabrous, 11’—18’ high. Sheaths glab- 
rous, the lower very short; ligule none. Stem leaves rigid,

Panicle 2’ long or less, oval, the few branches spreading ; 
spikelets 1}’’ long, elliptic, nearly glabrous. The autum-

Common.—This species is closely related to P. commutatum from 
which itis separated by its slender, strict habit, more narrow, rigid 
and spreading leaves approximate atthe topof the culm. Dry shady
