Of the species of Dipladenia figured in this Magazine, 

 D. illustris is very closely allied to two, namely, I), acu- 

 minata, t. 4828, which has large branched stipular pro- 

 cesses, very much larger flowers with narrower more acute 

 corolla-lobes and a more cylindric upper half of the tube, 

 and D. splendent {Ecliites splendens, t. 3976), which has a 

 shorter corolla-tube, and acuminate leaves, cordate at the 

 base. Both these differ further from D. illustris in their 

 membraneous leaves with distant arching nerves. Of the 

 few other plants figured in this work under Dipladenia, 

 two do not belong to the genus, namely J). Harrisii, 

 t. 4825, which is an Odontadenia, having amongst other 

 differential characters a cupular erect disk surrounding 

 the ovary, and a very different calyx and stigma, and
