Croton humilis is a mainly West Indian species extending from southernmost Florida (Collier and Monroe counties) to the Bahamas, Cuba, Hispaniola, Jamaica, and Puerto Rico, and up the Caribbean coast of Mexico to southernmost Texas (Cameron, Hidalgo, Starr, Willacy, and Zapata counties). Texas plants have more stamens (30–35) than Florida plants (15–20).
