This, about 2 m tall species, once grew in the wet forests of the Kaluanui Valley and the Waikane Valley in the Ko'olau Mountains on the island of O'ahu.

The species had long-petioled, up to 21 cm long leaves, which were about 2 to 7 cm wide. They were sparsely hirsute on the upper surface, densely velvety short-pilose on the lower surface.

The flowers, as in all polynesian species of this genus white in colour, appeared in small groups of two to five in cymes arising from the leaf axils.
