 surface scaberulous j mouth of sheath hairy. Spikes solitary or fascicled, 2^5 in. 

 long, slender, erect, rarely branching; gl. I of pedicelled spikelets subulate or

 disposed of as follows by Hackel : —

 length.

 plant that "Vf'aUich's n. 8868 B is exceedingly like it." But that number of 

 Wallich's Herb, is Batzeburghia pvZekerrima, and there is no B under it.
