Fifteen new species of Begonia L. from Sumatra are described and illustrated, in Begonia sect. Bracteibegonia (B. beludruvenea M.Hughes sp. nov. and B. jackiana M.Hughes sp. nov.), B. sect. Petermannia (B. harauensis Girm. sp. nov.), B. sect. Platycentrum (B. leuserensis M.Hughes sp. nov.), B. sect. Reichenheimia (B. fluvialis M.Hughes sp. nov., B. halabanensis M.Hughes sp. nov., B. karangputihensis Girm. sp. nov., B. kemumuensis M.Hughes sp. nov., B. korthalsiana Miq. ex M.Hughes sp. nov., B. kudoensis Girm. sp. nov., B. lilliputana M.Hughes sp. nov., B. olivacea Ardi sp. nov., B. raoensis M.Hughes sp. nov., B. simolapensis Ardi sp. nov.) and B. sect.
