Flowering specimens of the pretty Hoya here figured were 
communicated to us by Mr. Lowe, of the Clapton Nursery, who 
received the plant from the Eastern Archipelago, gathered either 
in Singapore or in Borneo. It probably is a native of both those 
islands, and of the Malayan Islands generally, being unquestion- 
ably the H. Cumingiana of Decaisne in De Candolle’s 5 Prodro- 
mus,’ from the Philippine Islands (n. 1480 of Mr. Cuming’s dis- 
tributed specimens). There are, indeed, some trifling discre- 
pancies between the character in the ‘ Prodromus ‘and our spe- 
cimens, almost wholly, however, depending on the more or less 
pubescent character, a circumstance extremely liable to vary. 
Descr. A. climber, with terete, green branches, slightly pu- 
bescent, as are the very short petioles, the peduncles, and calyz. 
Leaves coriaceous, elliptical-ovate, cordate at the base, suddenly
