at the base of the panicle and partly enveloping it. Leaves plane, candi 
chartaceous, linear-lanceolate, 6—12’ long and 6—9” broad, pubescent 
at the mostly open sheaths and the bases of the blades with soft spreading 
whitish hairlets, spinuloso-scabrous and mostly ciliate at the margins. 
Ligule short-ciliate. Panicle large, open, 8—14‘ & 3'/2—10’, its rays 
filiform, either single or 2—5 (in large forms even 7 or 8) in the lower 
nodes with a length of 3—8‘, patent but the lowest suberect, straight, 
angular, scaberulous, ciliate at their bases, dividing from the middle up- 
ward with branchlets patent. Spikelets on pedicels of their own length
