Origin and Habitat: Mexico, This species is widely distributed as a large number of small, isolated populations in a big area extending over 600 km, from central Coahuila in the north to Queretaro in the south, and the species is also found in the states of Coahuila, Nuevo León, Querétaro, San Luis Potosí, Tamaulipas, and Zacatecas (its extent of occurrence is about 60,000 km²) and has a very large population (ca 100,000 mature individuals).
Altitude: It grows at elevations of around 1000-1900 metres.
Habitat: Commonly called "living rocks," they are edaphic specialist plants widely distributed in and around the edges of the Chihuahuan Desert (The habitat is locally classified as matorral desértico micrófilo and mezquital extradesértico). They are scattered in a large number of small, isolated populations, generally on limestone derived gypsum silt plains and on hills. The area where they grow must be quite wet during the rainy season (Summer). Some of these areas become flooded periodically during the summer rainy season. In the same area it is possible to find several plant species like: Dasylirium longissimus, Thelocactus bicolorSN|3420]]SN|3420]], Mammillaria echinataSN|9136]]SN|9136]], Agave strictaSN|568]]SN|568]], Lophophora williamsiiSN|1117]]SN|1117]], Glandulicactus uncinatusSN|3474]]SN|3474]], and Wilcoxia schmolliiSN|8678]]SN|8678]].
Ecology: This plants are extremely cryptic and are very difficult to spot as they blend in well with the terrain around them resembling dried mud. When they are found, it is usually due to their pinkish flowers. In times of severe drought the whole above-ground portion of these plants can shrink and be covered by mould, but the taproot remains alive. The main threats to this species are human settlements, waste dumps, illegal collecting, and local medicinal uses. Some localities have been partly depleted by illegal collectors.

Description: Ariocarpus kotschoubeyanusSN|2127]]SN|2127]] are very flat geophyte cacti that produce small star-shaped rosettes. They in most cases don't reach more than only a few centimetres above the ground. Although they can form clumps, often only a small disc of tubercles can be seen flat at the soil surface, however these plants grow a large tap root below the surface of the compost.
Stem: Usually solitary, rarely giving rise to side shoots from old areoles, flattened on top, depressed centrally.
Tubercles: The tubercles are deltoid dark olive green with no spines and lie flat on the soil surface. They are more long than wide, closely packed and divergent, sharply angled apically.
Areoles: The tubecles forms a central longitudinal areolar groove extending to the tips on the adaxial surfaces of the tubercles, woolly, 1-3 mm wide, 5-10 mm long.
Roots: Each plant has a large turnip-like taproot, which lies below the soil surface and serves for water storage.
Flowers: These plants have a woolly crown, from which emerge bright pink-violet flowers up to 2.5-5 cm, 2 times wider than long when fully expanded. Flowers are diurnal and last for 3 to 4 days. The white-flowered variety was described as var. albiflorus.

Blooming time: Mid-September onwards.
Fruits: White or green with lots of seed.
