Aztekium hintonii

Aztekium hintonii is a small cactus in the genus Aztekium, scientifically described and published in 1992 by Charles Edward Glass and Walter Alfred Fitz Maurice from a plant discovered by George Sebastian Hinton. It grows as a solitary spherical to short columnar stem up to about 10 centimetres across and 6 to 10 centimetres high, with 10 to 15 sharp-edged ribs marked by very fine transverse wrinkles and two or three strongly curved spines up to 13 millimetres long. Its magenta flowers are 1 to 3 centimetres across. The species is endemic to the north of the Sierra Madre Oriental, in the municipality of Galeana, Nuevo León, where it lives at 1100 to 1200 metres on gypsum cliffs with xeric scrub, among other cacti. It grows slowly and is often grafted to speed it up, and it is easier to cultivate than Aztekium ritteri although easy to lose in its first years.
