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]

Distribution

Found in Florida, Georgia, Mississippi, Louisiana, and Texas. Listed as vulnerable in Texas.[4]

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, Q. incana, Q. virginiana, Q. myrtifolia, Q. chapmanii, Serenoa repens, and Ceanothus.[3]

Phenology

Flowers May through June and fruits June through November.[3]

Fire ecology

It has been observed growing in burned wetland slash pine savannas[3].

Pollination

The following Hymenoptera families and species were observed visiting flowers of Stylisma villosa at Archbold Biological Station: [5]

Megachilidae: Dianthidium floridiense
