1. Cupaniopsis macropetala is a rather variable species, especially in shape and texture of the leaflets.
2. NGF 46853 tends to have a more appressed indumentum. Clemens 121, NGF 33021, and van Royen 5482 have longer petioles, the last specimen also has more leaflets than all other specimens. Clemens 670, 1104 have long petiolules. Kanis 1135 and LAE 61135 have large flowers and petals with a 2.4 mm long claw.
