Cochemiea CERRALBOA - Cerralvo cochemiea, Mammillaria cerralboa, Mammillaria.
Cochemiea is a genus of plants in the cactus family (Cactaceae), comprising about 25 species native to Mexico and southern regions of the United States.
The genus is represented by plants with cylindrical, often solitary or branching stems covered with spine-bearing areoles. Leaves are reduced to small tubercles. The stems can reach various sizes depending on the species.
Flowering occurs in spring and summer. The flowers are funnel-shaped, symmetrical, up to 7 cm (2.8 in) long and up to 3 cm (1.2 in) in diameter, positioned at the apex of the stem. Flower coloration varies from bright pink to red. After flowering, berry-like fruits form, containing small black seeds.
Cerralvo cochemiea is a narrowly specialized cactus with elongated cylindrical stems, solitary or sparsely branching, covered with large tubercles. Areoles bear dense clusters of thin white radial spines and 1-3 stiff central spines, of which one is usually hooked and dark. The overall coloration of the plant is grey-green, but practically invisible under the dense covering of spines.
Flowering begins in spring. Flowers are large for the genus, funnel-shaped, bright pink or crimson, with a white tube and yellow stamens, forming in the apical part of the stem. Fruits are oblong, bright red, containing small black seeds.
