Campanula uniflora L.


Family: Campanulaceae

Distribution: Utah: Uinta and La Sal Mountains, Daggett, Duchesne, Grand, San Juan, Summit, and Uintah counties; Alaska and Yukon, south to Colorado; Eurasia (Welsh et al. 1993); northern Canada, Alaska, western mountains of US, occurrences generally very scattered (Hultén 1968).

Plants Seen or Cited: No entries in the New Mexico Natural Heritage Program Database, but two collections at UNM. New Mexico: Mackay. No. 9t-1. July 1969, Taos county. On the west facing slope of Wheeler Peak above 12,500 ft elevation. Confirmed by Nancy R. Morin (MO) 1993. Colorado: Mackay. No 7c-237. 8 July 1967. Huerfano county. Hill, eastern exposure, 37E36'10" N, 105E29'18" w, elev. 12,000-12,500 ft.

Habitat: Alpine tundra, often in talus or rock stripes, at 3,355 to 3,965 m (Welsh et al. 1993); dry stony ridges on tundra and in the mountains, to at least 1,500 meters [in Alaska] (Hultén 1968).

Discussion: Although its populations are scattered, the plant is widespread in the New World arctic and alpine habitats as far south as northern New Mexico. It is apparently not considered rare in Colorado (Spackman et al. 1997) or Utah (Atwood et al. nd). It probably is rare in New Mexico and its presence in the state may be an interesting example of vicariance in a species that was probably much more widespread in the Pleistocene, but its broad distribution indicates that it should not receive special status in this state. Although rare in New Mexico, this species is widely distributed and fairly common in northern North America.
