Plants usually solitary but sometimes branching to form clusters. Stems spherical to broadly obovoid, often with flattened tips, dark gray-green, 6-9 cm (2.4-3.5 in) high, 6-10 cm (2.4-3.9 in) in diameter. Tubercles conical, ascending, to 20 mm (0.8 in) long, glands usually absent. Central spines 4, erect or spreading, straight to slightly curved, sometimes shaggy or twisted, whitish, 17-43 mm (0.7-1.7 in) long. Radial spines 9-20, whitish, usually straight, 12-30 mm (0.5-

1.2 in) long. Flowers pale pink or deep rose purple, glossy, 3.5-6.5 cm (1.4-2.6 in) long, 3-5 cm (1.2-2 in) in diameter. Fruits dark green to pale gray-green, very fleshy, to 21 mm (0.8 in) long. Distribution: southwest Texas along the Rio Grande, and neighboring Coahuila, Mexico. Coryphantha ramillosa is listed as threatened in the U.S. Endangered Species Act. Field studies have shown, however, that it is more widespread than originally thought and may not be threatened in most parts of its range.
