description
Gymnocalycium parvulum grows individually or sprouting with gray-green, spherical shoots when old and reaches heights of up to 3 centimeters with diameters of up to 3 centimeters (rarely up to 5 centimeters). The nine to 13 ribs are clearly bumpy. Central spines are absent. The five to seven almost bristle-like, slightly curved, grayish white to white or light brown radial spines are mostly on the shoot surface. They are up to 4 millimeters long.
The slender tubular to funnel-shaped, white flowers have a purple throat. They reach a length of 4.5 to 6 centimeters and have a diameter of 3 to 4 centimeters. The bluish green, slightly frosted fruits are spindle-shaped to club-shaped. They are almost 3 centimeters long and can reach a diameter of up to 1.8 centimeters.
