It is a shrub or small tree with elliptic to oblong leaves, and male and female flowers on separate plants, each with 4 to 6 tepals.

Wilkiea kaarruana is a shrub or small tree that typically grows to a height of 5–12 m (16–39 ft) and has thick, corky, fissured bark.

[3][4] The specific epithet (kaarruana) refers to Kaarru (pronounced "Kaa-roo") Creek, where several plants, and the first female examples, were found.
