- Comments
- Var. collina is the most widespread var. of T. cordifolia in Virginia, occurring throughout the Piedmont, with a few occurrences in the n. Coastal Plain and lower elevations of the mountains. It is readily distinguished by its clumped habit and lack of stolons. The current map is based on the map in Nesom’s revisional paper (Phytoneuron 31: 1-61, July 2021), modified slightly by Virginia herbarium data. If this taxon is accorded full species status, as Nesom argues for, then the name Tiarella cordifolia would apply to John Clayton’s type; see Nesom (2021) for details.
- Habitat
- Var. collina occurs in mesic to dry-mesic slope forests, ravines, and well-drained alluvial forests, usually in moderately to strongly base-rich soils. It is frequent throughout the c. and s. Piedmont; infrequent in the n. Piedmont, and rare in the mountains (low elevations) and inner Coastal Plain.
