Hoya campanulata, Blume Bijdragen, p. 1064. 
Physostelma ? campanulatum, Decaisne in DeCand. prodr. 8. 633. 
This very curious plant is a native of Java, where it was 
found by Dr. Blume, who describes it as an inhabitant 
of mountain thickets on the west of the island ; it is called by 
the natives Tjunkankan, and flowers all the year round. Its 
introduction is due to Messrs. Veitch, of Exeter, to whom it 
was sent by Mr. Thomas Lobb, and from whom we received 
the specimen now represented in April, 1846. 
Its habit is altogether that of a thin-leaved Hoya, but 
its peculiarly formed corolla gives it a different appearance. 
On this account M. Decaisne removes it to the genus Physo- 
stelma, but as he does so doubtfully, and as it wants the 
bladdery coronet which is proper to that genus, giving it its 
name, it does not seem desirable that the current nomenclature 
should be disturbed. 
It requires the same treatment as Hoya carnosa.
