Malacothamnus
''Malacothamnus'' (bushmallow) is a genus of shrubs found throughout much of mainland California and on three of the Channel Islands. Outside of California, ''Malacothamnus'' is known from the northern half of Baja California and from a few disjunct locations in Arizona and Nevada. Plants of this genus are most commonly found in early-successional, post-burn plant communities.Kearney, T. H. 1951. “The Genus Malacothamnus, Greene (Malvaceae).” Leaflets of Western Botany VI (6):113–40. ''Malacothamnus'' are currently thought to be most closely related to the '' Iliamnas'' of the US interior and the '' Phymosias'' of Mexico, Central America, and the Caribbean. Taxonomy Taxonomy in the genus Malacothamnus has been controversial due to overlapping morphological variation and differences in opinion about how to treat that variation.Kearney, T. H. 1955. “Notes on Malvaceae VII: A New Variety in Malacothamnus.” Leaflets of Western Botany VII (12):289–90. Bates, D. M. 2015. “ ...
