Discussion

Dendromecon harfordii grows only on the Channel Islands. Plants with paler leaves from the southern islands (extant on Santa Catalina Island, once present on San Clemente Island) have been called D. rigida var. rhamnoides (Greene) Munz [= D. rigida Bentham subsp. rhamnoides (Greene) Thorne] and are considered to be of conservation concern.
