This white-flowered subshrub was first discovered in 1987. When it was placed on the Endangered Species List in 1991 there were 10 to 20 individuals known to exist, growing on cliff faces in the moist forests of the Waianae Mountains.[3] By 1997 these were gone.[2] The plant exists in cultivation, and several individuals have been outplanted in appropriate habitat. As of 2008 three of these have survived. They are protected inside fenced enclosures.[4]
