(Discussion copyrighted by Flora of North America; reprinted with permission.)

Some ornamental malvaceous trees have been introduced to California, none of which is known in the flora area outside of cultivation. These include the Mexican Robinsonella cordata Rose & Baker f. and, from Australia and New Zealand, Hoheria glabrata Sprague, Plagianthus divaricatus J. R. Forster & G. Forster, and P. regius (Poiteau) Hochreutiner. Malope trifida Cavanilles from the Mediterranean region, and the subshrubs Alyogyne Alefeld from Australia, species of Anisodontea C. Presl from South Africa, and Lavatera species from the Mediterranean are sometimes grown as ornamentals; they are not naturalized in the flora area.

Genera ca. 110, species ca. 1800 (42 genera, 220 species in the flora).
