Mammillaria plumosa is a species of the genus Mammillaria in the cactus family(Cactaceae). The specific epithet plumosa means 'feathery, feathered'.
description
Mammillaria plumosa , forms hilly groups up to 40 centimeters in size. The individual plant bodies are only 6 to 7 centimeters in height and diameter. The individual plants consist of 8 to 13 very soft and cylindrically shaped warts which do not contain any milky sap. The axillae are very woolly. About 40 white and soft radial spines with a length of only 3 to 7 millimeters lead to the feathery (feathery) impression and ultimately contributed to the naming. Central spines are absent.
The white and only 15 millimeters large flowers appear, as with all mammillaries, in the wreath. The fruits are cubic in shape, deep purple and just like the flowers 15 millimeters in size. The seeds are blackish brown to black in color.
