Cultivated by Mr. Philip Miller, as far back as 1731, 
in the Physic Garden, Chelsea; but, we believe, has very 
rarely blossomed in this country. In the Kew Catalogue, 
the season of its flowering is left in blank; to mark that 
the period when it did so had not been then ascertained. 
A figure of the flower has been thought entitled to an 
engraving and text in the Transactions of the Horticultural 
Society. Tt Son 
We are obliged to Mr. Colvill, of the Chelsea Nursery, 
for the sample for our drawing, which was done in the 
course of last summer. 
The species is native of the West Indies.
