Description

Cochemiea armillata initially grows solitary but later forms groups. The plants are slender, cylindrical, and can reach up to 30 cm (12 in) in height and 4 to 5 cm (1.6 to 2.0 in) in diameter, which usually grows with 3 to 12 stems that emerge at the height of the base or sometimes higher. They have firm, blue-green, conical to cylindrical warts without milky sap. The axillae are covered with wool and bristles. Each plant has 1 to 4 strong, yellowish-gray central spines, which darken with age and are partly hooked, measuring 1 to 2 cm (0.39 to 0.79 in) long. The 9 to 15 grayish white radial spines are thin, bristly, straight, and 0.7 to 1.2 cm (0.28 to 0.47 in) long.

The bell-shaped or funnel-shaped flowers are pink-creamy yellow, 1 to 3 cm (0.39 to 1.18 in) long, bell-shaped or funnel-shaped up to 2 cm (0.79 in) in diameter. The filaments are pink with yellow anthers. The stigma is also pink, with 5 to 7 lobes up to 5 mm (0.20 in) long, pinkish red. The red, club-shaped fruits are 1.5 to 3 cm (0.59 to 1.18 in) long and 7 to 10 mm (0.28 to 0.39 in) in diameter, containing black seeds, up to 1 mm (0.039 in) long by 0.5 mm (0.020 in) wide.[3]

Distribution

Cochemiea armillata is native to Baja California Sur, Mexico ranging from San José del Cabo area and as far as La Paz.

Taxonomy

It was first described as Mammillaria armillata in 1900 by Mary Katharine Brandegee.[4] The specific epithet armillata is Latin for 'decorated with clasps,' referring to the species' thorns. In 2021, Peter B. Breslin and Lucas C. Majure reclassified it into the genus Cochemiea.[5]
