[wikipedia] Rarity, Range: Sidalcea hickmanii ssp. anomala - Cuesta Pass checkerbloom is a rare subspecies known only from the vicinity of the Hwy. 101 Cuesta Pass in the southern Santa Lucia Mountains, in San Luis Obispo County, where it is limited to serpentine substrates. It has deeply lobed to almost compound leaves. While rare it becomes locally abundant in areas recently burned by wildfire.[3] (link added by Mary Ann Machi)
