Distribution[edit]

Begonia lamdongiana is endemic to Vietnam. It is known from only a few collections in Bidoup-Nui Ba National Park.

Habitat[edit]

Begonia lamdongiana is found in shaded slopes under constantly humid, frequently foggy primary broadleaved forest at elevations of around 1,500 m.

Characteristics[edit]

Begonia lamdongiana is a rhizomatous plant with large, ovate to suborbicular leaves that are up to 25 cm long and 20 cm wide. The leaves are densely setose on the upper surface and lack maculation. The flowers are small and actinomorphic, with a thyrsoid inflorescence.

Flower Details[edit]

The flowers of Begonia lamdongiana are bisexual and actinomorphic. The tepals are 3-5 mm long and yellowish or reddish. The stamens are numerous and shortly golf-club shaped. The ovary is trigonous-ellipsoid and 3-winged.
