Several inflorescences (some of them with the uppermost leaf attached 
to the peduncles) collected by A. Whyte in Nyasaland on the Masuku 
Plateau, between 6500 and 7000 feet, may represent another species 
of the genus described here. The panicles are less distinctly secund, 
the tips of the glumes more herbaceous and spreading, and the spikelets 
more gaping during flowering, thus imparting a slightly different facies 
to the plant. There is also frequently a g flower with the lower floret. 
The name is intended to indicate the more or less herbaceous nature 
of the outer parts of the spikelets (xAoy, herb ; &yvy, chaff)—O. Srapr.
