[wildmacro.com] Comparison to C. umbellata: One-seeded pussypaws (Cistanthe monosperma, formerly Calyptridium monospermum) is a North American plant which thrives in gravely soil and raises or lowers its flowers in order to thermoregulate. This common perennial herb is often mistaken for the very similar Mount Hood pussypaws (Cistanthe umbellata), but can be differentiated by multiple stems branching from a single rosette. Some resources place this plant in the miner's lettuce family (Montiaceae). (link added by Mary Ann Machi)
