Discussion

Variety arenicola is restricted to Miami-Dade, Monroe, and Palm Beach counties. A. M. Ferguson (1901) treated a collection of this variety as Croton betulinus Vahl, but that is a distinct, perennial species from the West Indies.

Variety septentrionalis is by far the most widespread variety of Croton glandulosus in North America, and the only one present north of Florida in the east and north of Oklahoma and Kansas in the Midwest.
