Notes: See comments under C. parviflora. Two closely related subspecies occur in our region:
1. Basal leaf blades widely elliptic to egg-shaped, the bases abruptly tapered; inflorescence more or less unstalked; only leaf stalks often red................ ssp. depressa (A. Gray) J. Miller & Chambers
1. Basal leaf blades diamond- or triangular-shaped, the bases squared off; inflorescence more or less stalked; plants and leaf stalks often red................... ssp. rubra
Moist to dry sand dunes, meadows, open forests and rock outcrops in the lowland, steppe and montane zones; rare on SE Vancouver Island, the Gulf Islands and the lower mainland (ssp. depressa), frequent in SC BC (ssp. rubra); S to SD, CO and CA.
