Sida ciliaris
Sida ulmifolia
Sida ciliaris is found in Broward and Miami-Dade counties and the Florida Keys and in central and southern Texas. The stems can be procumbent but not distinctly mat-forming, and they are often ascending, not flexible, and tufted. The flowers are sometimes described as being salmon-colored; that feature, the congested terminal leaves and flowers, and the adnate stipules are quite distinctive.

Sida ulmifolia is pantropical and weedy but thought to have originated in Central America. In previous floras it and S. planicaulis have been treated as S. acuta Burman f., but that is a different species from those from Brazil, Guatemala, Mozambique, Sri Lanka, southeastern Asia, several Pacific islands, and Australia. Under different names, S. ulmifolia has been reported also from New Jersey and ballast.
