Ariocarpus kotschoubeyanus is small cactus, growing up to 3 inches (7.5 cm) in diameter (usually much smaller), reaching flowering size at slightly more than 0.5 inch (1.2 cm) in diameter. Plants are flat-topped, growing flush with the surface of the ground. Tubercles are small, triangular, and bear felted groves along their midlines. Flowers open to just over 1 inch (2.5 cm) across, and may range from nearly white or shell pink to bright magenta.
