Abuta, Batschia, Anelasma, Triclisia, and Syrrhonema, the petals 
are altogether wanting, as they are apparently deficient in Fi-

Coscinium is exclusively an Asian genus, generally inhabiting 
the islands of the Indian Archipelago. Its species are all climb- 
ing plants, with very large, thick, coriaceous, coarsely nerved 
leaves, which are generally covered beneath with thick tomentum : 
they are oblong, sometimes palate, in other cases peltate, and 
supported by long and very strong petioles, which are tumid 
and tortuous at both extremities.
