Pipturus ruber A. Heller , Minnesota Bot. Stud. 1: 815 1897.
Kaua`i, Kaholuamanoa [Kaholuamanu], above Waimea, [below Gay & Robinson's house, stream banks]. 4000 ft. 1-8 October 1895. Heller 2852.
[GH, NY [mfc!], US!].
Note: Collection 2852, pro parte. Although at least three different collections were included under Heller 2852, Heller specifically gave the date of 4 October in the protologue, the date on the MIN sheets and therefore consider it the holotype. Other collections distributed under Heller 2852 were made: 2-9 September (BISH! ) and 10-16 September (US!), and are not types. The labels on at least some of the specimens give the more general date of 1-8 October (GH).
