Type information:
Holotype [F]. A.A. Heller 2831. 24-30 September 1895. Kaua`i: Kaholuamanu, above Waimea, between forks of Waimea River. Isotype(s) [GH [photo BISH!]].

Note: Collection 2831, pro parte. Three collections were distributed under Heller 2831 (see discussion under Nototrichium fulvum). Sherff used collection made 24-30 September from shaded site along the river as the type for this name. The other material labeled 24-30 September is from a slope above the river and serves as the type for N. sandwicense var. decipiens Sherff, and also the type for N. fulvum Schinz. Another collection numbered Heller 2831, not part of the type of any of these names, was made 10-16 September. Although Sherff did not cite an isotype at GH, he labeled the BISH photo of the GH sheet as N. sandwicense var. helleri and wrote the date as 24-30 September. K. N. Gandhi has confirmed that the date on the GH sheet is 24 September, which is the date Heller gives in his publication for this material.
