The handsome Cotyledon which forms the subject of our 
illustration is very distinct from any of the other species of 
this genus now in cultivation, though among these it is, 
perhaps, more nearly allied to the familiar C. gibbiflora, 
Moe. and Sessé, than to any other. But from C. gibbiflora 
it differs widely in the form and colour of its Jeaves, and in 
the rich orange tint of its corolla, which is very glaucous on 
the outside. ‘The branches of the inflorescence are shorter, 
more erect and stiffer. C. subrigida was first discovered in 
Mexico, in October, 1892, by Mr. C. G. Pringle, growing 
on ledges of cliffs in the Tultenango Cafton. The plant 
from which the material for our figure has been obtained 
was presented to Kew in 1905 by the authorities of the 
Natural History Museum, Washington, U.S.A., under the 
Juny, 1912.
