Tlie generic name. Cotyledon, is derived from the 
Greek kotele, a cavity, in allusion to the cup-like 
leaves of some of the species contained in this genus. 
We have adopted the generic distinction of Bieber- 
stein. De Candolle has divided the genus Cotyle- 
don, and our present subject is the Umbilicus sem- 
pervivum of his arrangement. 
It is a remarkably pretty plant, deserving of a 
place in every collection of al})ines ; whether in 
dower or out of dower, it will arrest the eye, for its 
crowded rosulate leaves never lose their healthy neat 
appearance. 
Our drawing was taken from a specimen in the 
Birmingham Horticultural Society’s Garden, and 
we are informed by 3Ir. Cameron, that planted in 
sandy loam, and placed in a cold frame during 
winter, it succeeds admirably, and in autumn admits 
of increase by division of its offsets. 
We are not aware of the plant having hitherto 
been fully exposed during winter; it has been too 
rare to admit of the experiment ; it may, however, 
be doubted, whether it could sustain the frosts, com- 
bined with the moisture of our climate.
