description
Mammillaria bombycina is a species that forms groups up to 80 centimeters in size. The individual shoots sprout very easily from the base, which significantly speeds up this process. They are spherical to club-like, light green and reach up to 20 centimeters in length and 6 centimeters in diameter. The parting is often sunken. The individual about 11 to 18 warts are firm, conical to cylindrical and somewhat rounded. The areoles are round, later elongated with a little wool. The axillae are provided with plenty of wool. The 30 to 40 radial spines are only between 2 and 10 millimeters long, thin, stiff and white. About 2 to 4 central spines are also only 0.7 to 2 centimeters long. They are thin, stiff and amber to white. The lowest are also the longest.
The small funnel-shaped flowers reach a size of 1.5 centimeters and are light carmine-red in color with darker central stripes. The fruits are whitish to club-like. The very small seeds are black.
