Leaves erect or ascending, 1’—2’ long, 2’’—3’’ wide, lan- 
ceolate, the middle ones longest, the upper much reduced, 
the lower pilose beneath, the upper pubescent with long 
scattered hairs on the upper surface,appressed pubescent, 
often papillate, beneath. Panicles 13’—2’ long, broader 
than long, the branches wide-spreading somewhat fasci- 
cled, rather few-flowered; spikelets 1’° long, broadly ob- 
ovate, apiculate, the first scale one-third the length of the 
pubescent second and third. Spikelets generally red, 
or purplish. 
Closely related to P. villossissimum from which separated by its gen- 
erally ascending habit, erect leaves, the upper reduced, and shorter 
usually ascending pubescence. District of Columbia: Kearney; 1897.

Stem leaves erect or ascending, longest near the base of 
the stem, much reduced in size upward, the largest 2’— 
3’ long, 2” wide, long taper-pointed, glabrous above, be- 
neath more or less papillose-pubescent. Panicle long ex- 
certed, 2’—3’ long pyramidal, the flexuous fascicled 
branches spreading, at length reflexed. Spikelets

Intermediate in size, habit, and general characters between P. ciliife- 
rum and P. demissum, smaller than the former and larger than the 
latter. Type material collected by the writer at Chapel Hill, N. C.
