Gymnocalycium fischeri is a species of plant in the genus Gymnocalycium from the cactus family(Cactaceae). The specific epithet honors the Czech cactus collector Ladislav Fischer.
description
Gymnocalycium fischeri grows individually with bluish-gray-green, flat spherical shoots that reach heights of up to 6 centimeters with a diameter of 8 to 10 centimeters (rarely up to 15 centimeters). The eight to twelve straight ribs are deeply notched and tubercular. The areoles, which are initially dirty and white , are later bare. The single central spine , rarely up to four, is only formed on older plants. The five to seven (rarely up to nine) radiating, awl, rigid radial spines are gray-brown. They are black-brown at their base and light horn-colored at the top. The radial spines have a length of 1.2 to 2.2 centimeters.
The funnel-shaped, variable ivory to light pink flowers have a dark pink throat. They are up to 8 centimeters long and 7 centimeters in diameter. The blue-green fruits are spindle to club-shaped and reach a length of 2.5 to 3.8 centimeters. They tear open vertically.
Distribution and systematics
