Melicope cornuta (Hillebr.) Appelhans, K.R. Wood & W.L. Wagner comb. nov. Fig. 3D

Platydesma cornuta Hillebr., Fl. Hawaiian Isl. 72. 1888.

Note.

As was typical for Hillebrand in the Flora of the Hawaiian Islands, he cited localities for which he saw collections and would only sometimes cite collector information (when someone other than himself made the collection). In this case he cited three localities (Halemano, Wailupe, and Pauoa) indicating he collected or saw material from each one of them. As such these collections must be considered syntypes. Stone (1962a) indicated the K sheet and the GH sheet cited below as holotype and isotype. They represent inadvertent selection of a lectotype and isolectotype. A number of additional syntypes from all three cited localities are known but can with certainty not be considered isolecotypes because the two specimens selected by Stone have no locality on the label other than O‘ahu and Kaua‘i.

Type.

O‘ahu: s. l., W. Hillebrand s.n. (lectotype, designated by Stone, J. Arnold Arbor. 43: 423. 1962: K [K000717606, image!]; isolectotype: GH [GH00044164, image!]. Additional syntypes: O‘ahu, Halemanu, Hillebrand s.n. (BISH [BISH1016374, specimen!], US [ US 00101497, specimen!]); O‘ahu, Pauoa Valley , Hillebrand & J. M. Lydgate s.n. (BISH [2; BISH1016375, BISH1016476, specimens!]; O‘ahu, Wailupe (MEL [MEL587728, image!], with a photo at BISH); and a fragment made by J. Rock of B sheet, without locality (BISH [BISH1016377, specimen!]).
