Flora of Virginia Name/Status
Rhododendron viscosum (L.) Torrey
Rhododendron viscosum var. serrulatum has a more southern distribution than var. viscosum, and is largely confined to the Atlantic and Gulf Coastal Plains. Although the two taxa are sympatric in this region and have often been lumped, Weakley (2020) has elevated the serrulatum variant to a species, based on morphology and distribution. We take a more conservative, varietal approach here, pending further evaluation of its distinctiveness and validity.
Acidic alluvial swamps, flatwoods, and seepage swamps. Frequent in the se. Coastal Plain counties but also scattered in the c. Coastal Plain; disjunct to Albemarle Co. in the Piedmont and Giles Co. in the Ridge and Valley.
