Rank Reasons

Confined to open, moist montane habitats from Idaho and Wyoming. Infrequent in one mountain chain in Montana.

Range Extent Comments

Southern Bitteroot Mountains in Montana (Lackschewitz 1991); northern and central Wyoming (Dorn 1988); northern Idaho (Davis 1952). Report from Southwest Alberta (Argus and White 1978) is in error - likely based on specimen CAN288334. Specimen annotated to Saxifraga oregana var montanensis by Packer, 1980.

Occurrences Comments

Infrequent in Montana (Lackschewitz 1991; data for Saxifraga oregana var. subapetala).

Ecology & Habitat

Habitat

Wet areas in the mountains (Dorn 1988). Ledges and permanently moist meadows in subalpine and timberline zones (Lackschewitz 1991; data for Saxifraga oregana var. subapetala).
