This plant seems to connect the genera Rostellaria and 
Anisostachya, having the inflorescence of the latter, with the 
calyx of the former. 
The Rostellaria tenella, N. ab E., is common to Senegal and

the Gaboon Coast, by Captain Middleton, in 1787; Schwabea 
ciliaris, N. ab E., extends from Senegal to Nubia and Abyssima-
