Notes
Known only from a single plant at Pt. Reyes NS from 1947; a similar plant was collected along the road to McClure’s Beach in the 1960s, but was not preserved for verification. Suitable habitat exists, but re-discovery attempts have been unsuccessful; needs field surveys. Similar to C. affinis and C. wightii, but occurs in different habitat. A synonym of C. chrymactis in TJM (1993); name misapplied. Not in TJM 2. See Leaflets of Western Botany 5(5):91-92 (1948) for original description.
