About Waimea
A shrub with red-brown hairs and conspicuous red glands. Coarsely crenate ovate-to-elliptic leaves are pale green above and gray-olive beneath, with bright-red veins and red glands below. Pistillate flower clusters have red calyces; tiny achenes are pale yellowish-gray to brown. 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.
