The first author circumscribes this species broadly to include material from both Taiwan (where the type was collected) and several provinces in E and S China. By contrast, Wen (Cathaya 15-16: 90-93. 2004) treated Aralia decaisneana as endemic to Taiwan, placing all populations on the mainland in her substantially revised A. chinensis.
