Discussion
Populations of Boltonia caroliniana present in eastern South Carolina to southeastern Virginia are atypical in array and leaf dimensions. They are characterized by broad, oblanceolate or obovate leaves subtending the branches of the arrays, stiffly ascending peduncles, and lilac rays; they were described as B. ravenelii. J. T. Morgan (1966) argued that some of the plants collected in Virginia “would key out to B. caroliniana while others from the same population better fit the description of B. ravenelii.” Therefore, she placed B. ravenelii in synonymy of B. caroliniana. Detailed studies of these populations and the biology of the species may resolve their taxonomic status.
