In the overlapping areas of Agave montana and Agave gentryi , intermediate forms are known.
Agave montana grows in Mexico in the states of Nuevo León and Tamaulipas on limestone slopes in woodland at an altitude of 3000 to 3400 m and can be found scattered on limestone slopes of the high mountain regions of the Sierra de la Marta . It grows in inhospitable areas with severe frosts in the winter months and can survive short periods of frost down to minus 15 ° C when dry.
