Description
Gymnocalycium ochoterenae grows individually with olive green to brownish, flattened spherical to hemispherical shoots and reaches heights of 3 to 4.5 centimeters with diameters of up to 8 centimeters. A stubby, branched taproot is formed. The 9 to 16 wide and flat ribs are rarely slightly humped. There is a central spine, which is often missing. The 3 to 5 (rarely 1 to 7) brownish-yellow to whitish-yellow marginal thorns that are curved back towards the plant body or radiate in a comb-like manner have a darker tip and are 1 to 1.5 centimeters (rarely up to 2.2 centimeters) long.
The funnel-shaped, white flowers have a light pink throat. They reach a length of 3.5 to 5.5 centimeters (rarely up to 6.5 centimeters) and have a diameter of 3.5 to 5.5 centimeters. The green to dull red fruits are barrel-shaped and 1.5 to 2 centimeters long.[3]
Distribution
Gymnocalycium ochoterenae is widespread in the Argentine provinces of Córdoba and San Luis at altitudes of 500 to 1500 meters.
Taxonomy
The first description was made in 1936 by Curt Backeberg.[4] The specific epithet ochoterenae honors the Mexican botanist Isaac Ochoterena (1885–1950).
