Stenocactus ochoterenianus is a species of cactus native to the deserts of Mexico.

Description

Stenocactus ochoterenianus grows singly with depressed, spherical, bluish-green ribs and reaches a height of up to 8 cm (3.1 in) with a diameter of up to 10 cm (3.9 in). The approximately 30 narrow ribs are wavy and widened by the yellowish areoles . The four flat and wide central spines are yellow and become straw-colored with age. The upper ones are 5–6 cm (2.0–2.4 in) long and 2 mm (0.079 in) wide. The 22 or more needle-shaped radial spines are white. They are all the same length, up to 1.2 cm (0.47 in). The plant body is often obscured by the spination.^[3] The flowers are pale pink or pale greenish yellow, 2.5 cm (0.98 in) long. The spherical fruits are greenish with white scales.

Distribution

Stenocactus ochoterenianus is endemic to Mexico where it is found in the states of Queretaro and Guanajuato. It has also been reported in Hidalgo, Jalisco, Aguascalientes, Zacatecas and San Luis Potosí.^[3]
