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 (FSU). This species is commonly mistaken for S. aquatica when not flowering[3].
Distribution
Ecology
Habitat
In the Coastal Plain in Florida, S. villosa can occur in longleaf pine/scrub oak sand ridges, moist lake shores, and sandy longleaf pine-Carya floridana-oak woods. It has also occurred in disturbed hammocks and along canals through burned wetland slash pine savanna (FSU Herbarium). Associated species include Quercus laevis, Q. incana, Q. virginiana, Q. myrtifolia, Q. chapmanii, Serenoa repens, and Ceanothus (FSU Herbarium).
It has been observed to be more common in disturbed areas of scrub habitats (FSU Herbarium).
Phenology
Flowers May through June and fruits June through November (FSU Herbarium).
Seed dispersal
Seed bank and germination
