Keckiella corymbosa occurs in the coastal ranges from the Central Coast to the North Coast regions of California. D. D. Keck (1936) argued that indument variation has no coherent pattern within K. corymbosa. D. C. Michener (1982) proposed that widespread introgression involving multiple species might be responsible.
