146 MR. Н. №. RIDLEY ON THE WEST-AFRICAN 
Var. LONGISPICATA. Capitulo intermedio elongato, cylindrico semiunciali, capitulis latera- 
libus duobus parvis, rarius nullis ; squamis szepe purpureo-punctatis, foliis latioribus. 
Sierra Leone, frequens in herbidis prope Freetown, no. 6989. 
Also collected in Madagascar by Hilsenberg and Bojer, in Herb. Brit. Mus. 
This variety has very much the habit and general appearance of K. cylindrica, Nees, 
but the spikelets are flattened and not swollen as in that species. "The leaves are 2 lines 
in diameter, somewhat broader than those of the typical form. 
The plant is a native also of India and Malaya, but seems to be most abundant in 
Africa. The flowering-season in West Africa seems to be February and March, as the 
specimens gathered in December were in bud, and those in May almost past flower.

The affinity of this plant is with К. melanosperma, Nees, from which it may be distin- 
guished by its more numerous and longer leaves, larger number of involucral leaves, and 
neuration of the glumes. The leaves are about 1 line in diameter, the involucral leaves 
very long, attaining a length of 6 inches.
