Abstract

Begonia togashii Nob. Tanaka & C.-I Peng (Begoniaceae), a new species from central Myanmar is described and illustrated. The presence of a rhizome, basal protandrous staminate flowers and distal pistillate flowers, 2-locular ovaries and placentas with two branches place it in sect. Platycentrum A. DC. It is somewhat similar to Begonia thomsonii A. DC., which was described from India, but is also in northern Myanmar. Begonia togashii, however, is distinct in having sub-symmetric basal leaves with a glabrous upper surface, 3-tepalled carpellate flowers and glabrous capsules. Thus far B. togashii is known only from Myanmar.
