Discussion

If the types of the names Cistus incanus and C. creticus Linnaeus are not conspecific, plants in the flora area called C. incanus should be known as C. creticus. Cistus villosus Linnaeus has been misapplied to plants belonging to C. incanus (and/or C. creticus).

Cistus incanus is known from the north and south Central Coast Ranges, northern South Coast Ranges, San Gabriel Mountains, Western Transverse Ranges (Liebre Mountains), and the Peninsular Ranges.
