Foliato; ramoinfimo 7 em. long. cum ramulo brevi basali. Spiculæ 6:5—7 mm. 
long. ; pedicellus brevior 0:5—1 mm. long., longior 1:5-2:5 mm. long. Gl. I. 
4:3—4:6 mm. long., П. cirea 6 mm. long. ; flos fertilis 4 mm. long. 
Ап interesting addition to this genus, hitherto known only in two species 
from Madagascar. Тһе African species differs in the more herbaceous 
character of the spikelets, which are moreover setose, the absence of the awn 
from the lowest barren glume, and the spreading branches of the panicle.
