Discussion | Varieties ca. 20 (5 in the flora). Croton glandulosus is widespread in the New World, with a complex pattern of variation. The classification here follows B. W. van Ee et al. (2009). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Croton soliman is most similar to C. humilis. In the flora area, C. soliman is found only in Cameron County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
