Discussion | Croton linearis in the flora area is found only in Martin, Miami-Dade, Monroe (Keys only), Palm Beach, and St. Lucie counties. There has been some confusion in the past with the application of the name C. cascarilla (Linnaeus) Linnaeus to this taxon, but C. cascarilla is now considered to be a synonym of the West Indian C. eluteria (Linnaeus) W. Wright (B. W. van Ee and P. E. Berry 2010b). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 2 (2 in the flora). Croton lindheimerianus is one of the bifid-styled species in sect. Heptallon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
