Shrub with slender branches to 2 m tall, leaves alternate or very rarely opposite. Diagnostic features of the species include alternate, 5-11-nerved leaves, distinguishing it from the morphologically very similar D. linearis. Flowering apparently occurs mostly in September and October.
This uncommon species is found only on O'ahu in the Wai'anae Mountains in mesic forests and open ridge habitats at elevations ranging from 600-1,150 m. The sites occupied by the species receive about 75-200 cm of annual precipitation.
