stipules free from petiole, 1-veined, linear, 5–8 mm, shorter than petiole;
petiole 10–25 mm, to 1/2 length of blade, stellate-tomentose;
blade broadly cordate to ovate-lanceolate, to 6 cm, reduced distally, 1–2 times longer than wide, base cordate, margins dentate to base, apex acute, surfaces softly velvety-tomentose.
usually crowded at stem apex;
stipules partially adnate to petiole, 1-veined, linear to oblanceolate, 4–12 mm, usually longer than petiole;

Sida cordifolia
Sida ciliaris
A velvety-tomentose herb sometimes used in herbal medicines, Sida cordifolia is believed to have originated in India, but has been widely spread in warmer regions globally. In many areas it is considered to be an invasive weed. There is considerable variation in the flower color patterns; the velvety-tomentose indument and retrorsely barbed, relatively large or conspicuous spines can help in identification.

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.
