Coastal dunes, mostly in stabilized hind dunes or on cliffs flanking the shore, < 100 m.
Perennial herb, becoming somewhat shrubby in older plants, gray-green becoming purplish, bristly, generally non-glandular; stems with an abundance of short axillary shoots; leaves oblong to rounded, fleshy, generally unlobed, or with three minor apical lobes, the tips truncate-rounded; inflorescence to 20 cm long, bracts to 20 mm long, widely wedge-shaped to widely obovate, lobed as in the leaves, bright red most frequently, but also varying in shades to yellow; calyx divided 1/3–1/2 dorsally, more deeply ventrally, and < 1/8 on the sides; flower long-nonglandular- and short-glandular-hairy; corolla 20–30 mm long, beak about as long as the tube (Wetherwax et al. 2013).
February to December (blooms throughout the year).
Sunset State Beach (Santa Cruz County); Salinas River State Beach, Marina State Beach, Point Lobos State Natural Reserve (Monterey County).
Endemic to the dunes in central California from Pt. Reyes south to Big Sur (Marin, San Francisco, Santa Cruz, and Monterey counties).
Most closely related to C. mendocinensis and C. wightii of the North Coast of California. The Santa Cruz County occurrence on the north shore of the Monterey Bay was still extant as of 2014. Collections from the North Coast of Santa Cruz County are part of a putative polyphyletic complex that may involve C. affinis, C. subinclusa ssp. franciscana, C. latifolia, C. foliolosa, C. wightii, and C. applegatei (West 2015). Needs study.
At Salinas River State Beach, this species was limited to foredune sites, being absent from both beach and hind dunes (Bluestone 1981). CNPS (2015) distribution fails to reflect documented occurrences in San Francisco County, where the type was collected, and where possibly now extirpated (Howell et al. 1958); plants reported in Howell (1949) for Marin County are C. wightii. Once more common and widespread in our region, it is declining in abundance. It is a partial root parasite but may not be able to use introduced ice plant (Carpobrotus spp.) as a host. It merits CNPS List 1B status and local consideration under CEQA.
