Coryphantha robustispina is a species of plant in the genus Coryphantha from the cactus family(Cactaceae). The specific epithet robustispina means '(Latin robustispinus) thorny'. English common names are "Devil's Pincushion", "Needle Mulee", "Pima Pineapple Cactus", "Pineapple Cactus", "Robust Pincushion" and "Stout Needle Mulee".

description

Coryphantha robustispina usually grows individually with spherical to egg-shaped, cloudy gray-green shoots and reaches heights of 5 to 15 centimeters with diameters of 5 to 9 centimeters. The egg-shaped to cylindrical warts are quite firm and up to 3 centimeters long. One or more nectar glands are located in the deep wart groove. The one to four straight, curved or hooked central spines are whitish to gray and have a darker tip. They are 1.2 to 5 inches long. The six to 16 whitish radial spines are 1.1 to 3.5 inches long. The lower ones are as thick as the central spines, the rest thin.

The dark golden yellow, light greenish yellow or cloudy yellow flowers are 4 to 6.5 centimeters long and reach a diameter of 5 to 7.5 centimeters. The cylindrical fruits are green and up to 5 centimeters long.

Distribution, systematics and endangerment

Coryphantha robustispina is common on grasslands in the United States in the states of Arizona , New Mexico, and Texas, and in the Mexican states of Chihuahua and Sonora .

It was first described as Mammillaria durangensis in 1856 by George Engelmann . Nathaniel Lord Britton and Joseph Nelson Rose placed them in the genus Coryphantha in 1923 .

The following subspecies are distinguished:

  • Coryphantha robustispina subsp. robustispina
  • Coryphantha robustispina subsp. Scheeri
  • Coryphantha robustispina subsp. uncinata

Coryphantha robustispina subsp. robustispina was in the Red List of Threatened Species of IUCN in 2002 as " Endangered (EN) , d". H. endangered, classified. In 2013 it was named “ Least Concern (CR) ”. H. listed as not endangered.
