erally puberulent ; ligule none. Leaves ascending, oblong- 
lanceolate, 13’ leng or less, about 2’’ wide, 1’ longestand 
broadest near the base of the culm, the upper reduced 
in size, glabrous. Panicle short-peduncled or sessile, 
l’—2’ lone, the branches short, flexuous, spreading; spike- 
lets obovate, 1’" long, contracted at the base, glabrous. 
Related to P. Webberianum, but distinguished by being much smaller 
and ascending from a geniculate base. Common in the pine barrens.
