Croton
See list of 2 species in this genusCroton glandulosus L. var. septentrionalis Muell.-Arg. was reported from CT by Magee and Ahles (1999), but specimens are unknown. Croton monanthogynus Michx. was once collected about the base of a foundation at the Arnold Arboretum in Suffolk County, MA. The herbarium collection, Palmer 47076 (A), does not suggest this species was naturalized; therefore, the species is not included in the flora.
