Mammillaria celsiana Cactus plant

Mammillaria celsiana Description: Mammillaria muehlenpfordtii is a massive globose cactus with bright carmine flowers. It is solitary when young, but each single stem begins to divide dichotomously to form two stems as it matures, this process repeats several times giving rise to small clustered groups and occasionally to large mounds with dozen of heads. Seen from above the central whorl of woolly areoles resembles a sunflower head.
Stems: Individual stems globose, becoming cylindric with age, 10-15 cm tall (or more), 7-15 cm in diameter, apex somewhat sunken and woolly, dark green, blue-green or grey-green.
Mammillaria celsiana Tubercles: Conical to pyramidal-shaped, compact, without latex.
Axil: Woolly and with white bristles.
Tubercles arrangement: 13-21.
Areoles: Small, round, woolly when young.
Radial spines: 24 to 50, about equal up to 4 mm long, glassy white or yellowish, bristle-like, radiating, nearly covering the body.
Central spines: Usually 4, rarely 2 to 7, somewhat longer than the radials, terete, rigid, pale yellow, more or less recurred pointing outward, and markedly unequal, 2 to 40 mm long, lowermost
longest, brownish yellow, becoming grey with brown tips.
Flowers: Small in a ring near the top of the cactus on previous years growth, 10-15 mm long, bright carmine to rose-red with reddish-brown outer petals.
Blooming season: Summer.
Fruit: Red.
Seed: Brown.
