There are two species of ladies' tresses in British Columbia: hooded ladies' tresses (Spiranthes romanzoffiana) and Ute ladies' tresses (S. diluvialis). Ute ladies' tresses is a recent addition to the flora of British Columbia and Canada. It was first reported for the province by Curtis Bjork and Terry McIntosh on the east shore of Lake Osoyoos in 2008. It had been found previously by O. and G. Westby at Mahoney Lake in 2006, but not recognized at the time as a distinct species. Along Osoyoos Lake, it grows in association with Carex viridula Michx. and/or Eleocharis rostellata (Torr.) Torr. (Bjork et al. 2008). It is also found within a band of grasses and sedges along Mahoney Lake.
