description
Gymnocalycium gaponii grows individually with dull green to light olive-green, depressed spherical shoots , which reach heights of about 2.5 centimeters with diameters of 5 to 6 centimeters (rarely up to 8.5 centimeters). The eight to nine (rarely up to eleven) wide and flat ribs are notched transversely and divided into flat cusps with small, chin-like protrusions. The single central spine is only developed in large plants. The five to seven awl, rigid, straight or slightly twisted radial spines are bent towards the shoot. The radial spines are dirty white and have a brownish base. They have a length of 1.3 to 1.6 centimeters.
The slender white to light pink flowers are 5.7 to 6.5 centimeters (rarely up to 7.4 centimeters) long and have a diameter of 4.2 to 5 centimeters. When ripe, the olive-green fruits are elongated, egg-shaped to club-shaped and reach a length of 1.6 to 2.2 centimeters and a diameter of 0.8 to 1.3 centimeters.
