This is a shrub with sprawling branches lined with leaves growing in clusters of three. The solitary flowers are purple in color.[3] The plant grows only in the wet forests of the Pelekunu Mountains of Molokai. The most recent surveys revealed a total of twenty individuals, ten in each of the two populations.[2]
The plant is threatened by the invasion of introduced species of animals such as feral pigs and feral goats, and plants such as Koster's curse (Clidemia hirta) in its habitat.[2] The plant is vulnerable because of its small numbers; a single event could conceivably cause its extinction.[2]
Officials have released the leaf-eating insect Lius poseidon into the habitat as an agent of biological pest control against Koster's curse. It is too early to determine how successful this effort has been.[2]
