Discussion

Chelone cuthbertii occurs in the coastal plain and Appalachian regions. The species can be distinguished from others of the genus by its short petioles and purple-tipped staminodes.

Chelone cuthbertii is rare throughout its range, making it especially vulnerable to extinction. Drainage of wetlands and bog succession threaten the habitat where the species is found (NatureServe, www.natureserve.org/explorer).
