ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 281 
A rather small group of wide range, its most remarkable members 
being a few striking biennials from the Caucasus region. The species,

at least those in cultivation, divide themselves into two well-marked 
sub-groups. 
A. Sempervivoides sensu restricto. Rosettes Sempervivum- 
like, inflorescence dense, leaves sessile, flowers red or reddish : —

pilosum M. Bieb. 
B. Cepaea sensu restricto. Rosettes lax, inflorescence very lax, 
leaves stalked, flowers white or yellow. 
Cepaea L. viscosum Praeger. 
While the Sempervivoides group is almost confined to the Asia 
Minor area, the Cepaea group is mainly Chinese and includes several 
well-marked plants in both the white-flowered and the yellow-flowered 
sections.
