The genus ee Fenzl, is intermediate between Kaempferia, 
Linn., and Costus, Linn., with the former of which it has been united 
by Bentham aa ‘with as ie by Schumann. From Kaempferia it 
differs in the lateral staminodia being rudimentary or suppressed, and 
from Costus in its acaulescent habit. 
Another species, C. spectabilis, Fenzl, which has been figured in 
Curtis’s Botanical Magazine, t. 7992, is ‘widely spread in the eastern 
half of es from Senaar southwards to Nyasaland, and differs from 
the present plant in its larger size, obovate-cuneate (more rarely 
suborbicular) leaves, and comparatively shorter and broader corolla- 
tube. 
C. Dalzielii is said by Dr. J. M. Dalziel to grow all over Northern 
Nigeria, except in the north, but to flower only rarely. It is called 
in ov Sane language * takalmin zomo’ or hare’s slipper.—C. H.
