Benecke's Nipple Cactus is a variable species, usually
offsetting and not very large. It has white radial spines and brown
hooked centrals. Plants are solitary at first, later forming large
clumps up to 50 cm or more wide. Flowers are yellow, with radiating
star-like petals. The flowers open at night and close permanently
around noon. Benecke's Nipple Cactus differs from the rest of
Mammillarias and the differences are prominent when it flowers. The
flower-tube is up to 3 cm long and a flower of bright yellow petals
about 3 cm wide, one of the largest of its genus. Besides its seeds are
quite large and rough compared to those of other Mammillarias.
Benecke's Nipple Cactus is native to Southern Mexico.
