Great Basin Naturalist


Kane Lake Cirque lies in the western Pioneer Mountains of south central Idaho. An inventory of the high elevation flora of the cirque revealed the presence of 180 vascular taxa representing 95 genera and 30 families. Five alpine taxa are here documented from Idaho for the first time: Carex incurviformis Mack., Draba fladnizensis Wilfen., Potentilla nivea L., Ranunculus gelidus Kar. & Kir., and Ranunculus pygmaeus Wahlenb. Kane Lake Cirque also contains populations of four additional alpine taxa considered to be of conservation concern in Idaho: Erigeron humilis Graham, Parnassia kotzebuei Cham., Saxifraga adscendens L., and Saxifraga cernua L.
