About Hāhā
An unbranched shrub with long, narrow elliptic leaves whose margins are conspicuously wavy. The lower leaf surface is hairy, and the blade grades into a winged stalk. Slightly curved hairy flowers are described as yellowish before full expansion. Obovoid berries are yellow. This native shrub is a component of Hawaiian vegetation. Monitoring mature plants, new recruits and occupied cover can assess persistence and replacement. The reviewed accounts do not establish a measured Kauaʻi population trend or quantify an ecosystem effect.
