Note: Sherff based his new species on Hillebrand's (Fl. Hawaiian Isl. 359. 1988) Stenogyne sessilis Benth. Y var. for which Hillebrand cited: "Maui! ridges above Waiehu and Wailuku, also Makawao (M & B 406); and perhaps Mauna Loa, Hawaii!" Sherff (1935) cited locality as "Waiehee, Waihu, or Wailuku." Date on BISH sheet is 1878, clearly an error since Hillebrand was in Hawaii from 1851 to 1871.
