Kew's Plants of the World On-line (POWO) accepts the spelling of this species as Luisia trichorhiza; most reference sources spell the species as L. trichorrhiza; this plant matches the description and keys to Luisia trichorhiza in King & Pantling's 1898, "The Orchids of the Sikkim-Himalayas"; matches the form in most available photos (OW, IOSPE, orchidroots, etc.), but appears to be variable in color.
