A beautiful half-shrubby plant, seldom seen in our 
Gardens, although far from being recently introduced. It 
is a native of Teneriffe, where seeds were collected by 
P. B. Webb, Esq., and sent to England to Mr. Young, of 
Milford, near Godalming, by whom a specimen in flower 
was sent to us in April last. 
* The Arabians called species of this genus kheirt, whence the word 
Cheiranthos has been compounded by the addition of the Greek for flower.
