I regret that at the time the drawing of this really handsome 
Apocyneous plant was made from specimens in the Royal Gar- 
dens, the glandular structure of the receptacle and of the in- 
side of the calyx was neglected to be examined, and I am at a 
loss whether to refer the species to Hehites or to Dipladenia. 
The general form of the flower seems to justify its being placed 
in the latter genus; if indeed the two be really distinct. ‘The 
plant seems undoubtedly new, and was sent from Santa Martha, 
New Grenada, by Mr. Purdie, in 1845. It requires the heat of 
a stove for its successful cultivation. The flowers are nearly 
equal in size, and the same in colour, as our yellow-flowered 
Species of A//amanda. Its blossoms with us are produced in May.
