Notes

Hederopsis is united with Macropanax because the species are very similar in appearance and in their technical characters. The sole difference is the number of cells in the ovary, 2 (or sometimes 3) in Macropanax and 5-6 (sometimes 4) in Hederopsis. This distinction does not seem adequate to split a few very similar species into distinct genera.
This genus is distinguished from Pseudopanax (China, New Caledonia, Tasmania, New Zealand, Chile) by the ruminate endosperm. Cf., .
