Common Name

Flora of Virginia Name/Status
Muscadinia rotundifolia (Michx.) Small var. rotundifolia
The treatment here follows Flora of Virginia and Flora of the Southeastern U.S. (Weakley et al. 2023) in recognizing the genus Muscadinia as separate from Vitis. According to FSUS, recognition of Muscadinia at generic rank is warranted by molecular studies, the long-recognized morphological distinctiveness of Muscadinia vs. Vitis s.s., the genetic distance of it from Vitis s.s., the different chromosome numbers (40 in Muscadinia, 38 in Vitis s.s.), and the standards of morphological distinctiveness of genera in the Vitaceae.
In a wide range of habitats, including alluvial, seepage, maritime, and tidal swamps; floodplain forests, wet flatwoods, depression ponds and swamps; sandhill woodlands, mesic to dry upland forests and clearings; maritime forests, woodlands, and dune scrub. Common in the Coastal Plain north to Stafford County and in the outer Piedmont north to Goochland County; rare in the inner Piedmont and mountains.
