Hedyotis degeneri

This is a branching shrub with clusters of flowers.[2] The plant is limited to the Waianae Range on Oahu. It grows on cliffs and ridges in forested mountain habitat. The main threat to its existence is the degradation and destruction of its habitat by feral ungulates such as pigs. The animals have been a vector for the introduction of alien plant species, which compete with native flora.[1]
