Species: Bryoerythrophyllum columbianum

A western North American endemic. In British Columbia, concentrated within a relatively narrow geographic area: principally in the south Okanagan Valley (e.g. near Osoyoos) and near Kamloops, although it also has been found near Spences Bridge, and at one site along the Fraser River in the Cariboo area (COSEWIC 2004). It is considered "relatively rarely observed/confirmed" within its range in BC (T. McIntosh pers. comm. 2008). In the United States, occurs in Washington, Oregon, California, and Idaho. Based on EOs and other range information, it appears that range extent is approximately 100,000 - 250,000 square km. Had been reported from the Northwest Territories (Nahanni National Park and vicinity) (Steere & Scotter 1978); however, R. Belland surmises that the NWT report was based on a mis-identification, since a thorough search of the relevant specimen databases did not uncover any confirmed reports from NWT (pers. comm. to M. Anions 2008). It had also been reported from Bolivia (Lewis 1981, McIntosh 1989), Peru (Menzel 1992), Nepal, India and Mexico (Zander 1978). However, these reports have all apparently been re-identified as other species; for example, the Bolivian collection has been re-identified as <i>B. fuscinervium</i> (Mitt.) Zand. (Zander, pers. comm. to T. McIntosh 2002).
