Description

Cochemiea cerralboa typically grows solitary and rarely forms groups. Its slender cylindrical shoots reach up to 20 cm (7.9 in) in height and 3 to 4 cm (1.2 to 1.6 in) in diameter. The yellowish-green warts are firm, conical to cylindrical, and lack milky juice. Axillae have short bristles. The plant features a strong, straight or sometimes hooked yellowish central spine, 1 to 2 cm (0.39 to 0.79 in) long, and about 10 yellow, straight radial spines, each up to 2 cm (0.79 in) long.

The funnel-shaped flowers are white with pinkish-brown central stripes, up to 2 cm (0.79 in) long and wide. The club-shaped fruits vary from greenish to purple-red and contain black seeds.[3]

Distribution

Cochemiea cerralboa is native to Isla Cerralvo in Baja California Sur, Mexico.

Taxonomy

It was first described as Neomammillaria cerralboa by Nathaniel Lord Britton and Joseph Nelson Rose in 1923.[4] In 2021, Peter B. Breslin and Lucas C. Majure reclassified it into the genus Cochemiea.[5]
