A native of the trunks of trees, not only in Java, but in other 
islands of the Indian Archipelago, according to Blume. In habit 
and mode of growth this species reminds one of the Hoya Bella, 
figured at our Tab. 4402; but it is much less elegant and 
attractive, and wants the pink eye which gives such effect to 
that species. The Indian Archipelago abounds in species of the 
genus once ranked under Hoya, and even by Blume himself; 
but this genus is now, by that author, divided into several 
genera ; and to the present species he has, in the letterpress to his 
“Rumphia’ above quoted, but not on the plate, given the generic 
name of Otostemma.* “ Ab Hoya,” he says, “recedit dentibus
