description

Mammillaria knippeliana grows singly, occasionally dividing dichotomously and sprouting. The fresh green shoots reach heights of 7 to 8 centimeters and a diameter of 6 centimeters. The solid pyramidal warts are square and blunt. The axillae are covered with white bristles. The 6  central spines are up to 3 inches long. The bottom and top are each the longest. They are spreading, needle-like and white with a red or brown tip. The 6 radial spines appear late. Like the central spines, they are only slightly weaker.

The yellowish flowers have a red central stripe. They are 1.5 inches long and 1 inch in diameter. The red elongated and spherical fruits are up to 9 millimeters long and 5 millimeters in diameter. They contain dark, yellow-brown seeds .

Distribution, systematics and endangerment

Mammillaria knippeliana is common in the Mexican state in Morelos near Cuernavaca .

It was first described in 1907 by Leopold Quehl (1849–1923).

The interpretation of this name is still open according to David Richard Hunt . The plants that have been labeled recently belong to Mammillaria karwinskiana in the broadest sense .

In the Red List of Threatened Species of the IUCN , the species is called " Data Deficient (DD) ", i. H. with insufficient data.
