Flaccidgrass

Pennisetum flaccidum Griseb.

Comments

provided by eFloras
This is a widespread and rather variable species, but it always has tough, spreading rhizomes, a glabrous inflorescence axis, and involucres of soft bristles. The bristles are usually glabrous, but occasionally a few hairs are present on some of the inner bristles. Specimens with axillary inflorescences (the basis of Pennisetum centrasiaticum var. qinghaiense) occur throughout the range of the species and do not merit separate status.

This species is a good forage grass.

Common in the higher alpine slopes, it is grazed by sheep and goats. Some collectors say it is a useful fodder grass.
