Euphorbia celastroides Boiss. var. hanapepensis Sherff, Bot. Gaz. (Crawfordsville) 97: 597 1936.
Kaua`i, along the Hanapepe River near the falls. 700 ft. 2-8 July 1895. Heller 2429.
Note: Collection 2429, pro parte. Other collections distributed under Heller 2429 were made 24-26 June (A, GH, BISH! , MIN!, NY [mfc!]), and are not primary type material. Sherff clearly distinguished between specimens of Heller 2429 collected 24-26 June and those collected 2-8 July. He cited only the US sheet as an isotype. Possible isotypes: CU, MSC. The paratypes cited by Sherff (F , GH, K, NY) probably all represent the same collection, although the locality on the K sheet is given as "Hanapepe and Wahiawa watershed," and the date is 24 June. Koutnik (1987) erroneously considered specimens at BISH, F, GH, K, and MIN to be isotypes. Wagner, W.L. & R.K. Shannon. 1999. Brittonia 51:422-438
