'''''Turbinicarpus''''' is a [[genus]] of  very small to medium-sized [[cactus|cacti]], which inhabit the north-eastern regions of [[Mexico]], in particular the states of [[San Luis Potosí]], [[Guanajuato]], [[Nuevo León]], [[Querétaro]], [[Hidalgo (state)|Hidalgo]], [[Coahuila]], [[Tamaulipas]] and [[Zacatecas]].

These succulent plants grow mostly on limestone soil (never on volcanic soil), at altitudes between 300 and 3300 meters above sea level.

''Turbinicarpus'' are usually confined to specific habitats, generally hostile for the majority of plants, mostly in very drained rocky areas, composed of limestone, sandstone, schist (neutral or alkaline), or in very acidic and humiferous underwood, or in gypsum veins, sometimes so pure that is almost white.

In particular, ''Turbinicarpus strictu sensu'' are adapted to extreme niches: more than 80% of the species grow in rock cracks or among the pebbles beneath them, where enough dust accumulated to enable root development. It would seem almost impossible that plants so small could survive in such an environment, however in those species that inhabit dry and exposed areas, the root is very thick, becoming a taproot and acting like an anchor on the slopes but, more important, as a water storage for the dry periods, capable of significantly retracting into the ground so that the stem is less exposed to the sun; the spines are often changed to adopt a very papery structure, capable of absorbing good quantities of water. Furthermore, the general look is extremely mimetic, thanks to the epidermis colour and the interlacing spines, guaranteeing a certain protection from eventual herbivores.

Turbinicarpus is a genus of very small to medium-sized cacti, which inhabit the north-eastern regions of Mexico, in particular the states of San Luis Potosí, Guanajuato, Nuevo León, Querétaro, Hidalgo, Coahuila, Tamaulipas and Zacatecas.

These succulent plants grow mostly on limestone soil (never on volcanic soil), at altitudes between 300 and 3300 meters above sea level.

Turbinicarpus are usually confined to specific habitats, generally hostile for the majority of plants, mostly in very drained rocky areas, composed of limestone, sandstone, schist (neutral or alkaline), or in very acidic and humiferous underwood, or in gypsum veins, sometimes so pure that is almost white.

In particular, Turbinicarpus strictu sensu are adapted to extreme niches: more than 80% of the species grow in rock cracks or among the pebbles beneath them, where enough dust accumulated to enable root development. It would seem almost impossible that plants so small could survive in such an environment, however in those species that inhabit dry and exposed areas, the root is very thick, becoming a taproot and acting like an anchor on the slopes but, more important, as a water storage for the dry periods, capable of significantly retracting into the ground so that the stem is less exposed to the sun; the spines are often changed to adopt a very papery structure, capable of absorbing good quantities of water. Furthermore, the general look is extremely mimetic, thanks to the epidermis colour and the interlacing spines, guaranteeing a certain protection from eventual herbivores.
