Note 3: Comparison of the genera Allophylus and Rhus by Mark Hyde

Allophylus species and species of Rhus both have 3-foliolate leaves and look superficially similar. The following are some notes which may help to separate Allophylus spp. from Rhus.

In flower, Allophylus can be separated by having petals and sepals in 4s (usually in 5s in Rhus) and in fruit by the ± spherical fruits (usually flattened in Rhus).

In leaf, Allophylus can usually be separated by the domatia which are never present in Rhus. Unfortunately, they are not always present in Allophylus.

Other possible differences are:
