This most distinct and handsome species was found in 
August, 1901, in cultivation at Amacamaca, near the City 
of Mexico, by Dr. J. N. Rose, of the United States 
National Herbarium at Washington, and a plant was sent 
by him in 1903 to Kew, where it flowered in June, 1904, 
The specimen figured is a young plant; in the adult state 
it is of a much larger size. C. elegans is one of the very 
few species of Cotyledon that are pubescent, and this 
character, in conjunction with its one- or two-flowered 
peduncles, readily distinguish it from all others. Although 
the peduncles bear so few flowers, their large size and 
brilliant colour make it one of the most attractive species 
yet introduced. Like most of its Mexican congeners, this 
species belongs to the section Hcheveria, and although Dr. 
Rose has published it under a new generic name, I can 
find nothing, either in habit, vegetative organs, or floral 
structure, whereby it can be generically separated. 
Descr.—A suffruticose, succulent perennial, branching 
from the base upwards, one to two feet high; branches, 
leaves, peduncle, calyx, and outside of the corolla softly 
and minutely pubescent. Branches a quarter to a third of 
an inch thick. Jeaves in small, lax, terminal rosettes,
