Mexico: Dense thicket of cacti in southern Puebla state

Cacti are often associated with deserts, but cactus diversity is actually highest within the tropics. Cactus densities are also often very high, as can be seen in this dense thicket of at least 4 species of cactus in southern Puebla. The tree in the upper right corner is Cercidium praecox. The tufts in its branches are a species of Tillandsia.
