This is hardly distinct from D. tiirbinatus, Gaertn. of India, Assam and 

 Burma, but that has larger and rounder leaves, pubescent buds, and more 

 acute calyx-lobes. Duvaliella problematica Heim, Biill. Mens. Par. 1892, 

 p. 1009, was a name given to what appears to be a scrap of this plant with 

 a long pointed gall, which Heim mistook for a fruit. It was collected in 

 Penang by Curtis, and there is a similar specimen from Cantley.
