Infra-generic Classification. Subgenus Acacia (syn. Phyllodineae) section Plurinerves
Type Citation. "Hab. Sandwich Islands, Oahu, on the mountains behind Honolulu, Hawaii on the side of the Mouna Loa and Mouna Kea."
Type Designation. Lectotype (designated by St. John 1979, publ. 1980: 358): Sandwich (=Hawaiian) Islands, Oahu, on the mountains behing Honolulu, U.S. Exploring Expedition, Wilkes (K); isotypes: GH,US. Source. St. John (1979, publ. 1980: 358).
Notes. A recent molecular phylogeneitic study indicates that A. heterophylla (Lam.) Willd. from Reunion Island is actually A. koa which colonized the Mascarene archipelago directly from the Hawaiian Islands not more than 1.4 million years ago (Le Roux et al., 2014). A proposal to conserve the name A. koa over A. heterophylla would be appropriate.
