Flora of Virginia Name/Status
Salix interior Rowlee
This taxon is often treated as a subspecies or variety of the western Salix exigua Nutt. However, G.W. Argus, a long-time expert on Salix and FNA author, argues (in FNA, Vol. 7) that "Salix exigua and S. interior hybridize and apparently intergrade in the western Great Plains; because the area of overlap is relatively small and distinctiveness of the two taxa is not compromised by hybridization and introgression, it is best to treat them as separate species."
River and stream banks, rocky flood-scoured shores and bars, sand and gravel bars, and ditches. Rare in all provinces, occurring here at the eastern edge of its range; known only from the Potomac River drainage in the n. Piedmont, the City of Virginia Beach in the se. Coastal Plain, and scattered localities in the sw. mountains.
