Bonamia menziesii is a member of the morning-glory family (Convolvulaceae). It is a vine or twining liana with branches that can measure up to 10 meters long. The leaves are usually leathery and oval shaped. Its flowers are white to greenish colored, funnel shaped and produced singly or in clusters of three on stalks.
Bonamia menziesii was historically known from scattered locations on Kaua`i, the Waianae Mountains of O`ahu, on Moloka`i, one location on Maui and on the eastern end on the island of Hawai`i. Today, it is known from a total of 28 populations consisting of a few thousand individuals.
Distribution & Occurrence
Bonamia menziesii is found on steep slopes as well as on level ground in dry to mesic forest and sometimes in wet forest at elevations between 150-625 meters (USFWS 1999).
