Tex., Mexico (Coahuila, Guanajuato, Hidalgo, Nuevo León, Querétaro, Tamaulipas, Veracruz).


Colubrina greggii is known in the flora area only in Cameron County. These plants and those in northern Tamaulipas have sparser foliar vestiture than those elsewhere in the range. The Texas plants also have leaves with obtuse to acute or barely acuminate apices, in contrast to the more typical acuminate apices over the rest of the range.

Colubrina greggii var. yucatanensis M. C. Johnston (southern Mexico and Central America) and C. greggii var. angustior M. C. Johnston (east central Mexico) both have been treated at specific rank (G. L. Nesom 2013).
