don deficiens) as a native of Mount Melhan in Arabia (lat. 14^ 40' N., 
long.44? E.), and adds that the plant is cultivated in Egypt. 
De Candolle erroneously considers Mount Melhan to be in Egypt. 
Hochstetter and Steudel refer an Abyssinian tomentose Kalan- 
choé (Schimperiana, A. Richard, Fl. Abyss. i. 310) to Forskahl's 
Cotyledon deficiens ; but no doubt erroneously, as A. Richard sus- 
pects. 
From the Botanical Magazine figure (tab. 1436, sub Cotyledone) 
of K. crenata, Haw. Synops. 109, Mann’s plant differs solely in the 
absence of any hairs, and the apparently darker-coloured flowers, the 
leaves being identical. .K. crenata is a native of Western tropical 
Africa. De Candolle does not describe K. crenata as at all hairy.

it resembles a good deal the common Indian M. scabrella.
