Discussion

Deinandra corymbosa occurs on the Central Coast and the Northern Coast and in the Outer South Coast Ranges and San Francisco Bay area. Plants with relatively large heads in glomerules from the Central Coast south of Big Sur have been treated as subsp. macrocephala; no subspecies are recognized here because of wide variation in head size and arrangement along the Central Coast north and south of Big Sur.
