This is hardly distinct from D. turbinatus, Gaertn. of India, Assam and 
Burma, but that has larger and rounder leaves, pubescent buds, and more 
acut« calyx-lobes. Duvaliella problematica Heim, Bull. 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.
