Taxonomic notes
Description
S. villosa is a perennial vine that has wiry, twining, thick, pubescent stems. The leaves are alternate, elliptical/oval, densely covered with white hairs and are held upright at a right angle to the ground, which reduces water loss from transpiration during the heat of the day. Inflorescence are solitary or in cymes of 3-7 flowers[1][2]. Flowers have white corollas and are about two centimeters broad[3]. This species is commonly mistaken for S. aquatica when not flowering[2].

It can be found in disturbed scrubs, hammocks and along canals through a burned wetland slash pine savanna. Associated species include Quercus laevis, Q. incana, Q. virginiana, Q. myrtifolia, Q. chapmanii, Serenoa repens, and Ceanothus[3].
