Plants flattened globose, gray-green, blue-green, or yellow-green, 3-25 cm (1.2-9.8 in) high, 4-30 cm (1.6-12 in) in diameter. Tubercles divergent, projecting above ground level, erect, crowded basally, more or less pointed or acute terminally, rounded or flat on top, 1.5-4 cm (0.6-1.6 in) long, 1-3.5 cm (0.4-1.4 in) broad, varying from nearly as broad as long to more than twice on long as broad. Areoles sometimes present at tubercle tips. Flowers cream colored to light yellow or white, occasionally with reddish midveins, 3-5 cm (1.2-2 in) in diameter. Fruits elongate, 10-25 mm (0.4-1 in) long. Distribution: Coahuila and Nuevo León south on both sides of the Sierra Madre Oriental into San Luis Potosí, Mexico.

Ariocarpus scaphirostris

Ariocarpus retusus is listed in Appendix I of cites. The Huichol use the cactus ceremonially though it is not known to contain psychoactive alkaloids (Chapter 2, under Cacti as Medicine). This widespread, extremely variable species has received a number of names but Anderson and Fitz Maurice (1997) believe that there are two subspecies. Subspecies retusus is variable but can best be characterized as gray-green or blue-green, with tubercles not sharply incurved and not usually sharply pointed, and with round areolar pads at the tips of the tubercles. Flowers are white to pinkish white. This subspecies is widespread throughout the Chihuahuan Desert from Saltillo south to San Luis Potosí. Subspecies trigonus usually is yellow-green, has tubercles that are usually strongly incurved and sharply pointed, and lacks areolar pads at the tips of the tubercles. Flowers are yellow or cream. This subspecies occurs primarily in the Tamaulipan thorn shrub vegetation from north of Monterrey and east of the Sierra Madre Oriental, and also in the valley of Jaumave, Tamauli-pas. Intermediate forms between the two subspecies are known to exist.
