Note

There is a single specimen from Burma in Paris (P), collected by Wallich from Toang Dong. The number 2726 which appears on this sheet is the number of the type collection. However the type itself was collected in Nepal. It is not clear whether the sheet in Paris belongs to the type collection or really is from Burma. It is probably better to assume that the locality is indeed correct, and therefore this species is included in this account. In addition, as the Burmese specimen bears only fruits, the floral description above has been taken from the type.
