Range DescriptionThis species is endemic to Mexico, where it occurs in the states of Nuevo León and Tamaulipas. The original range of this species extended from north of Monterrey, southwards on the east side of the Sierra Madre Oriental to approximately Ciudad Victoria. It is also commonly found in the Valley of Jaumave, west of Ciudad Victoria. However, much of this range has been modified by agricultural development, particularly that area east of the Sierra. The plants occur at numerous localities throughout the Valley of Jaumave.
