Polyscias oahuensis is a species of tree in the ivy family known by the common name 'ohe mauka.[2] It is endemic to Hawaii, where it occurs on all the major islands except for Niihau and Kahoolawe.[3]

This tree has compound leaves each made up of 7 to 15 dull leaflets. It contains a clear sap. The fruits are black or purple in color and their seeds are dispersed by birds. This was the most variable species of the formerly recognized genus Tetraplasandra.[3]

The tree grows in moist to wet island forests.[3]
