This very distinct species of Sitene is a native of the Cau- 
casian promontory, growing on the rocks, very common about 
the Constantino-montane hot-baths. There is a variety in 
Tauria, with wider flat leaves, less hoary. 
Communicated by Mr. Josepu Kuienr, of the Exotic Nur- 
sery, King’s Road, in June 1815.
