Isl . 243. 1913. - Type: Hawai'i : in dense forests of the summit mountain of the Kohala range, 12 July 1909, J. F. Rock 4222 (holotype: BISH, not located; isotype: GH [mounted on two sheets, GH00044160, GH00044161, images!]). Note. These two sheets are the only type material of this collection located. They were labelled as co-type, which was used at the time Rock published for the equivalent of isotype. Rock stated in his book that most of the specimens mentioned in the text were in the "college of Hawaii Herbarium", which are now incorporated into BISH. He specifically indicated the type of this new variety to be there, so the presumed holotype should be at BISH, but could not be located. Type . Hawai'i : 1851-1855, J. Remy 604 , ( holotype : P [P00636836, image!]; isotype: P [P00636837, image!]).
