Description:

Cyanea lanceolata subspecies lanceolata is a small woody shrub found only on the island of O`ahu in the Ko`olau Mountain Range. Currently, there are less than 300 plants left in the wild (USFWS 2001). The leaves of this species can become quite large and range from 6 inches to 2 ft in length. The inflorescences are usually comprised of 4 to 16 flowers, ranging in color from pale to dark magenta, often with lighter or darker longitudinal stripes (Wagner et al. 1999).

Where is Lanceleaf Cyanea (Cyanea lanceolata ssp. lanceolata) located in the wild?

Habitat:

Mesic valleys and wet forest, 300 to 915 meters elevation (Wagner et al. 1999). It was once a relatively common understory shrub in mesic and wet forests, but has become increasingly harder to find.

Distribution:

This species is found in the Ko`olau Mountain Range of O`ahu (Wagner et. al 1999).

Endemic to the island of Oahu, state of Hawaii. The remaining plants number fewer than 123. Feral, non-native pigs and invasive, non-native plants are serious threats. Also, non-native rats are known to represent a threat to Cyanea species in general.
