Material of this species was referred by Wen (Cathaya 13-14: 75-82. 2002) to Aralia leschenaultii, which is the correct name when treated in that genus. Frodin and Govaerts (World Checklist Bibliogr. Araliaceae, 68. 2004 ["2003"]) incorrectly referred to this species as A. fragrans (D. Don) Jebb & J. Wen, which is illegtimate because it is a later homonym. The two varieties recognized here were not retained by Wen (loc. cit.).

1 Leaflets (3-)5, papery or subleathery, margin ciliate to serrate.   13a var. fragrans
+ Leaflets usually 3, membranous or papery, margin entire.   13b var. forrestii
