Hesperomannia bushiana O. Deg. , Fl. Hawaiiensis, fam. 344. Hesperomannia bushiana. 1935.
Type information:
Holotype [BISH]. O. Degener , W. Bush and C. Potter, & K. K. Park 9981. 26 May 1935. O`ahu: [Ko`olau Range], along crest of middle Halawa Ridge, ca. 2.5 miles above makai boundary of Forest Reserve. Isotype(s) [BISH!, MASS!, NY [mfc!]].

Note: Collectors published as Bush, Potter, Degener, & Park, but specimen labels list collectors in order of Degener, Bush, Potter, & Park. Both BISH sheets are ex herb. Degener; the one that most resembles the illustration (and is the best specimen) is taken to be the holotype, although Degener wrote "co-type" on the label (he also wrote the list of institutions that dups. were to be sent to on the same label).
