Euphorbia kuwaleana (

Waianae Range.[1] Like other Hawaiian euphorbs, this plant is known locally as `akoko. It is a federally listed endangered species
of the United States.

This is a shrub that grows on bare, exposed basalt cliffs. The stems grow to a maximum length approaching one meter and they contain a milky sap. The new stems are reddish in color and age to a waxy gray. The leaves are oval to heart-shaped, up to 2.5 centimeters long, and slightly hairy on the undersides. The inflorescence is a cyathium occurring singly in the leaf axils or at the tip of the stem.

There are about 2000 plants remaining.[1] They are threatened by non-native plants and fire.[1]
