Prasoxylon

Prasoxylon is a genus of flowering plants in the family Meliaceae. It includes seven species which range from Nepal and eastern India through Indochina to southern China, Taiwan, Malesia, Sri Lanka, Papuasia, and Queensland.

The genus was first named by Max Joseph Roemer in 1846. 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 Prasoxylon was revived and re-circumscribed.
