Inflorescence a terminal corymb of umbels, glabrous; primary axis 5-15 cm; secondary axes 11-12, each 11-17 cm, with several terminal umbels of bisexual flowers and a few lateral umbels of apparently male flowers; peduncle 2-4 cm; pedicels 1-2 cm. Ovary 5-carpellate; styles united basally into a column, free arms recurved. Fruit globose, 5-6 mm in diam.; styles persistent. Fl. Dec-Mar, fr. Mar-May.

Deciduous and mixed evergreen forests; 1200-2000 m. Xizang, NW Yunnan (Gongshan) [Bhutan, NE India, N Myanmar].

The oldest name for this species is Gamblea longipes, for which Aralia kingdon-wardii is a nomen novum recently proposed because the combination A. longipes Truffaut had already been made for another species. In Pentapanax, however, the specific epithet "longipes" is available and is accordingly combined here.
