Origin: Native

selected vouchers: WTU

Notes: There has been disagreement and confusion regarding the author for this species. Online Jepson Manual has revised the treatment of authorship to Michx. on the following grounds:
"..... indicates that an explanation of the author correction from Rich. [in The Jepson Manual [Ed. 1]] to Michx. [in this Index] is presented in the notes under Fl. bor.-amer. in Stafleu & Cowan, TL-2 3:459 (1981); essentially, all internal evidence in Fl. bor.-amer. indicates A. Michaux as the sole author even though it is thought that L. C. Richard wrote most or all of the descriptions."

References: (none)
