Mammillaria rhodantha is a species of the genus Mammillaria in the cactus family(Cactaceae). The specific epithet rhodantha is derived from the Greek words rhodos for 'rose red' and anthos for 'blossom' and refers to the flower color of the species.
description
Mammillaria rhodantha usually grows individually, occasionally dichotomously branching or sprouting. The spherical to short cylindrical cloudy green plant bodies are seldom flattened. They grow up to 30 centimeters high and 7 to 15 centimeters in diameter. The obtuse conical to cylindrical warts are without milky sap . The axillae are woolly at first and have few bristles. The 4 to 7 central spines are straight or slightly curved, red to reddish brown. They are shiny and 1 to 1.5 inches long. The 13 to 28 radial spines are 0.6 to 1 centimeter long. They are thinly white to yellowish or sometimes also golden yellow in color.
The flowers are deep purple-pink. They grow up to 2 inches long and 1.6 inches in diameter. The cylindrical to club-shaped fruits are greenish to light pink-purple. They grow to be 1.5 to 2.5 inches long and contain orange-brown seeds .
