Seeds of this very pretty plant, which belongs to De 
CAnpo.ze’s second Section, “ Cuspiparia,” were received at 
the Royal Botanic Garden *, Edinburgh, in May, 1838, 
from 
* It is much to be regretted, that more of the history of this ornamental 
plant is not known to us. Since Dr. GRAHAM’S communication arrived, I 
have received fine specimens of the same plant through the kindness of Lady 
Mary Cartucart, of Cathcart, who received the seeds direct from Caboul, 
but accompanied by the information, that the plant was a native of Persia. 
This lady remarks, that the plants grow slowly and languidly in pots; but 
the moment they are transferred to the open border, free from all restraint, 
they become as vigorous as the common Wall-flower, and put up many 
flower-heads in succession. Ei .
