Giant cacti and spiny scrub abound.
The most common plants of the Mexican plateau are the agaves, yuccas and cacti, each of which is represented by a number of species.
In ascending from the coast-valleys there is first an arid range, where the great-branched cacti rear themselves up among the rocks.
Proceeding southward cacti become common, first a dwarfed species, and then a larger columnar form (Cereus quisco).
Palms are common, the chestnut abounds in many places, the cacti are almost as numerous as on the open plateau.
