The name of this genus derives from the Latin “turbinatus” meaning top-shaped, because of the top-shape growth of the stems. These small cacti are found in North-Central Mexico, where they typically grow on limestone soils, at altitudes ranging between 300 and 3,300 metres above sea level. Most species live in rock cracks or among the pebbles beneath them, while others can be found in humiferous substrate or even in areas characterised by chalky soils. They are, therefore, very adaptable plants that have learned to survive harsh environments. Spines vary considerably from species to species; some of them are even papyraceous and can collect fog and dew. Flowers come from the apex and range from white to light and dark pink. Many Turbinicarpus species are the first to bloom. Propagation occurs from seeds, which can be easily obtained from different clones. Gymnocactus was included in this genus. The international trade, reproduction, possession of these plants is regulated by the law; in particular by the Washington Convention on International Trade (CITES).
