Malacothamnus palmeri is a species of flowering plant in the mallow family known by the common names Cambria bushmallow and Palmer's bushmallow. It is endemic to San Luis Obispo County, California, where it is known from the Santa Lucia Mountains.

Taxonomy

Malacothamnus palmeri was first described in 1877 as Malvastrum palmeri. In some treatments, Malacothamnus involucratus and Malacothamnus lucianus have been treated as varieties of or synonyms of Malacothamnus palmeri. In 2021 morphological analyses revealed these to be three morphologically and geographically distinct species.

Identification

Malacothamnus palmeri is distinguished from the rest of the genus by the combination of a capitate to subcapitate inflorescence, glandular trichomes =7mm wide. Malacothamnus palmeri is distinguished from Malacothamnus lucianus by having glandular trichomes
