Didymocheton

Didymocheton is a genus of flowering plants in the family Meliaceae. It includes 41 species which range from eastern India through Indochina and southern China to Malesia, Papuasia, eastern Australia, New Zealand, and the South Pacific.

The genus was first named by Carl Ludwig Blume in 1825. Most of the species currently accepted were, until recently, included in genus Dysoxylum. A genetic study published in 2021 found that Dysoxylum is polyphyletic, and Didymocheton was revived and re-circumscribed.
