An Occurrence of the Hawkweed-Leaved Saxifrage, Saxifraga hieraciifolia, in Southern British Columbia, and its Palaeobotanical Implications
The Hawkweed-Leaved Saxifrage (Saxifraga hieraciifolia), normally found in the alpine tundra in the Arctic, has been collected at 445 m in parkland near Chase, British Columbia. The closest previously recorded occurrence was on the tundra of the Liard Plateau, northern British Columbia. The new occu...
