Discovered fairly recently in 1970, Cyanea asarifolia was known only from a single population of five or six plants above the bed of Anahola Stream on the island of Kaua`i. Recent attempts to relocate this population have failed and this population is now thought to be extinct. In 1991, another population of 14 mature plants and 5 seedlings was discovered at the headwaters of the Wailua River in central Kaua`i. In 1992, Hurricane Iniki heavily damaged the Cyanea asarifolia population, destroying all but 4 or 5 young plants. This single remaining population continues to be vulnerable to hurricanes, natural rock slides, competition with alien plants and animals, and over collecting. (USFWS 1987)
Cyanea asarifolia is an attractive small shrub with heart-shaped leaves and beautiful inflorescences comprised of up to 30-40 white with purple striped flowers. (Wagner et al. 1999)
Distribution & Occurrence
