Schizocarps 12–16 mm diam.; mericarps 6–10, 6–7 mm, apical face and margins sharp-edged, surfaces smooth to faintly ribbed, glabrous or puberulent on apical surface. Seeds dark brown, 4 mm, nearly as thick as long, notch slight. 2n = ca. 40.

Calif., introduced in Mexico, Central America (Guatemala), South America (Bolivia, Chile, Ecuador, Peru), Pacific Islands (New Zealand), Australia.

Discussion

Malva assurgentiflora, traditionally placed in Lavatera, has long been cultivated as an ornamental or windbreak in California and is native only on the Channel Islands. It has become naturalized on the mainland as well as in Mexico and sparingly elsewhere. The shrubby habit, large flowers with dark-veined petals, and thick, hemispheric, fruits make it distinctive; it is our only native species of Malva. The petals are often recurved with age, and the corky mericarps float and are tolerant of salt water. Further study may indicate that there are two distinct subspecies, as suggested by R. N. Philbrick (1980).
