Comparison of material previously assigned to the east Asian genus Evodiopanax (Araliaceae) with that of Gamblea from the eastern Himalayas and northern Myanmar shows that they comprise a single genus, with Gamblea having priority. A re-evaluation of taxonomic limits within the expanded genus leads to the recognition of four species: G. ciliata extending from India across northern Myanmar, southern China and far northern Viet Nam to eastern China, and including the newly recognized var. evodiaefolia, previously treated as a distinct species; the Japanese G. innovans; G. malayana in peninsular Malaysia and northern Sumatra; and G. pseudoevodiaefolia restricted to southwestern Guangxi and southeastern Yunnan Provinces in China and adjacent northern Viet Nam and Laos. Four new combinations are made and four names are lectotypified.
