Mammillaria rekoi is a species of cactus native to central and southwestern Mexico. [2]
Mammillaria rekoi has green stems that are either globe-shaped or somewhat cylindrical, growing up to 15 cm (5.9 in) tall with a diameter of 5–6 cm (2.0–2.4 in). The stems may be solitary or form clumps. The 4–7 central spines of the areoles are 10–15 mm (0.4–0.6 in) long, hooked or straight, and much stouter than the 20–30 radial spines which are 4–6 mm (0.16–0.24 in) long. The flowers are purple-pink to pink with darker midveins and are up to 15 mm (0.6 in) long. The ripe fruits are red with brown seeds. [3]
The species was first described by Nathaniel Lord Britton and Joseph Nelson Rose in 1923 as Neomammillaria rekoi. [4] Friedrich Vaupel transferred it to Mammillaria in 1925. [2]
Three subspecies are recognized: [2] [3]

It is endemic to the Chihuahuan Desert of the southwestern United States and northwestern Mexico. It is a small, variable cactus with a lengthy taxonomic history, and is often subdivided into a number of subspecies or varieties. It is usually found on steep, rocky habitats, primarily of limestone geology, in desert scrub or coniferous forest. A species of conservation concern, P. sneedii faces threats from poaching, urban encroachment, and wildfires.
