REMARKS

Begonia grandis is an extremely variable Chinese species. Hô.’s figure shows a geophyte with a distinct tuber and short stem that superficially resembles plants belonging to ssp. sinensis (A.DC.) Irmsch. Hô. called this plant “ var. chinensis Irmsch. ”, an invalid name. The identity of the plant illustrated cannot be confirmed as Hô. does not cite specimens nor does his sketch show flowers or fruits. Until authenticated specimens of B. grandis from Vietnam are located (there are none at P), this species should be excluded from the Vietnamese flora.
