- Comments
- This species was named by E.S. Steele from material collected near Millboro Tunnel, Bath County in 1907. Plants have basal leaves similar to Symphyotrichum cordifolium or lowerianum but those of schistosum are usually more truncate or broadly cuneate at the base. The most noticeable characteristic is the presence of elongate stolons, often with proliferations of new basal leaves at their tips. Stem leaves and inflorescence characteristics have caused some botanists to suggest genetic influence from Symphyotrichum prenanthoides or S. laeve and conferring hybrid status. An ancient hybrid origin is possible but the species has a unique and consistent set of characters and is behaving as a stable species in a region well known for unique and restricted taxa.
- Habitat
