Genus of flowering plants
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.
[1] 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.
