Stenogyne diffusa A. Gray var. glabra Wawra, Flora 55: 532. 1872.
Type information:
Holotype [W]. W. Hillebrand s.n.. 24 December 1862. Hawai`i: Laeha, high plateau. Isotype(s) [BISH! [probable]].

Note: Sherff apparently did not consider the two sheets at BISH to be isotypes. A small label giving "24 Dec 1872" on one of the BISH sheets must be an error for the 1862 on the other label on the sheet, as Hillebrand left Hawaii in 1871.
