Datum: WGS 84. Uncertainty: 50 meters. Coordinate Source: Topo plus waypoint.
Growing on rocks on top of NW facing cliff, adjacent to flat rocky bench approximately 80 m (horizontal distance) WNW of summit of Mt. Ellinor. Immediate vicinity mostly sparsely vegetated rock and talus, with scattered Luetkea pectinata and Micranthes tolmiei. Petals (5) white with many spots (yellow at base, to red near top); petal length ~5mm. Sepal margins (largely) glabrous. Basal leaves <4x as long as wide (~4.9 to 7.0 mm long, and 1.4 to 2.0 mm wide). Leaves tipped with sharp point. (NOTE: a difficult call for us between S. vespertina and S. austromontana - basal leaf and sepal margin characteristics weighted our decision towards S. vespertina.) Phenology: Fertile.
