Sida ciliaris
Sida lindheimeri
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.

Specimens from Florida identified as Sida lindheimeri are generally misidentified individuals of S. elliottii. Sida lindheimeri is widespread and occasionally common in south-central and southernmost Texas in approximately 40 counties, and it has been reported from Cameron and East Feliciana parishes in Louisiana.
