- Comments
- Flora of the Southeastern U.S. (Weakley et al. 2023) splits traditional Cornus into several genera (Chamaepericlymenum, Benthamidia, and Swida in our area) representing major clades in phylogenetic analysis. Even though Cornus treated broadly is monophyletic, the clades are also monophyletic and diverged millions of years ago, accorrding to Yu et al. (2017, PLOS One DOI:10.1371/journal.pone.0171361) and Fu et al. (2019, Molec. Phylogen. & Evol. 140: 106601). As evolutionary lineages, these clades are far older than many groups treated by taxonomists as genera and clearly merit generic status.

- Mesic and dry-mesic upland forests, boulder field forests, seepage swamp hummocks, clearings and borders; east of the mountains, it is more restricted to base-rich soils. Frequent in the mountains; infrequent in the inner Piedmont; rare in the outer Piedmont and Coastal Plain.
