This plant is a hardy biennial, and probably inhabits 
some part of the North of India, though it does not appear 
in the collections of either Dr. Royle or Dr. Wallich. 1t 
was raised by the Horticultural Society from seeds presented 
by John Nimmo, Esq. of Bombay, and flowered for the first 
time in August, 1838. It is a very pretty species, but its 
smell is heavy and unpleasant. 
It differs from C. uncinatum in its fruit, and in the leaves 
not being at all acpminate ; from C. microglochin, longiflorum, 
and grandiflorum in the cauline leaves not being rounded at 
July, 1839. o
