Loosely cespitose, the slender rhizome 
better developed than in the other species, 
the culms slender, erect, or spreading, freely 
branching, 30 to 60 cm tall, the nodes, at 
least the lowermost, pubescent, sometimes 
obscurely so; sheaths somewhat com- 
pressed, the lower rarely pubescent, a pubes- 
cent line across the collar, short-pilose along 
the margin at summit; ligule a dense line of 
short hairs; blades 5to15cmlong,4to7mm — gyeure 286.—Panicum leonis. 
wide (rarely but 3 mm wide), flat, narrower Peas Poa eae 
than the sheath at base; panicles from all the 
upper nodes, usually 2 to 5 cm long, relatively dense; spikelets 1.7 to 2 
mm long, the bristle from minute to longer than the spikelet (fig. 286). 
8 A P. utowanaeo differt laminis planis latioribus (usque ad 7 mm); nodis inferioribus pubescentibus 
Paniculis brevioribus densiusculis; spiculis 1.7-2 mm longis.
