Begonia melanobullata, also known as the Vietnamese black peak begonia or Vietnam ferox, is a flowering plant native to Vietnam. It was first found in limestone karst areas near the Sino-Vietnamese border. The plant is notable for dark, hair-tipped conical bumps on the upper surface of its leaves. It has red flower stalks and flowers, with seed capsules that are green with red streaks. It is similar to Begonia ferox and Begonia nahangensis but differs in size and leaf shape.
