Character Abstract
Identification Comments:
Subspecies Comments:
Phenology Comments:
Reproduction Comments:
Habitat Comments:Moist, seasonally saturated, slowly creeping, dark brown loam or sandy loam soils derived from glacial till, generally on steep north to northeast aspects, particularly just below bedrock constrictions in the soil flow that have resulted in extra churning and steepening of the soil and lowered vegetation cover, sometimes on Selaginella mats, in subalpine meadow openings in the subalpine conifer zone, with Selaginella watsonii, Draba oligosperma, Geum rossii, Potentilla fruticosa, Sedum debile, Oxyria digyna, Ribes cf. montigenum, Lithophragma glabra, Luzula comosa, Mertensia ciliata, Pinus albicaulis, etc.
Ecology Comments:
Inventory Comments:Surveys have been extensive, but a few more populations likely remain to be found in remote high-elevation areas of the Ruby Mountains.
