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.[2][3] Flowers have white corollas and are about two centimeters broad.[4] This species is commonly mistaken for S. aquatica when not flowering.[3]
Distribution
Found in Florida, Georgia, Mississippi, Louisiana, and Texas. Listed as vulnerable in Texas.[5]
Ecology
Habitat
In the Coastal Plain in Florida, S. villosa habitats include longleaf pine/scrub oak sand ridges, moist lake shores, and sandy longleaf pine-scrub hickory-oak woods. It can be found in disturbed scrubs, hammocks and along canals through a burned wetland slash pine savanna.
Associated species include Quercus laevis, Quercus incana, Quercus virginiana, Quercus myrtifolia, Quercus chapmanii, Serenoa repens, and Ceanothus.[4]
Phenology
Flowers May through June and fruits June through November.[4]
Fire ecology
Populations of Stylisma villosa have been known to persist through repeated annual burning,[6] and this species has been observed growing in burned wetland slash pine savannas.[4]
Pollination
Leafcutting bees such as Dianthidium floridiense (family Megachilidae) were observed visiting flowers of Stylisma villosa at the Archbold Biological Station:[7]
