Panicum xanthospermum Scribner & Mohr, sp. nov. 
A low, erect, cespitose, hairy perennial, 5 to 9 inches high, more or Jess branched 
from the base, with erect leaves and rather loosely flowered ovate or pyramidal pan- 
icles 1 to 2 inches long. Culms, leaves, and sheaths clothed with a soft pubescence 
of rather long lax hairs; nodes bearded with erect-spreading white hairs; sheaths 
shorter than the internodes, densely pilose; leaves lanceolate-acuminate, rounded at 
the base, gradually tapering to the apex, densely pilose beneath, more thinly so 
above, the margins narrowly cartilaginous, often somewhat involute toward the 
apex, those of the stem about 3, 1} 10 3 inches long, 2 to 3 lines wide, the basal ones 
somewhat shorter. Panicles slightly exserted, lax, pale; rachis smooth or somewhat 
pilose below; lower branches + to 1 inch long, flextious, gradually shorter above. 
Spikelets about 1 line long, elliptical, obtuse, pale yellow or straw-colored, con- 
tracted at the base, for the most part long-pedicellate; first glume about one-fourth 
as long as thespikelet, acute; second and third glumes equaling the flowering glume, 
about 9-nerved, rather thinly pilose-pubescent with soft, spreading hairs; flowering 
glume about } of a line long, elliptical, acute, very smooth. 
Near P. arenicola, from which it ditfers by its large yellowish spikelets.
