Flora of Virginia Name/Status
Cornus foemina P. Miller
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.
Bottomland forests, alluvial swamps, seepage swamps, stream banks, and tidal swamps; occasionally in mesic upland forests. Frequent in the Coastal Plain; infrequent in the outer Piedmont south of the James River; rare in n. Piedmont and mountains.
