Discussion | A report of Croton punctatus from Pennsylvania apparently was based on a transient appearance on ballast (E. T. Wherry et al. 1979). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 2 (2 in the flora). The affinities of Croton pottsii lie with C. lindheimerianus and C. monanthogynus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
