Gymnocalycium bruchii is a species of Gymnocalycium from Argentina.

Description

Gymnocalycium bruchii grows abundantly and forms multi-headed mats of dark green shoots that reach heights of up to 3.5 centimeters with diameters of 6 centimeters. The approximately eight to 12 (-17) low, straight ribs are rounded and tuberous. The one to three white or brownish central spines, which can occasionally be missing, are protruding. The twelve to 14 (up to 26) (rarely from seven) thin, bristle-like, glassy white marginal spines are bent back and 2 to 6 millimeters long.

The delicate violet-pink to white flowers, which are often unisexual, are usually 3.5 to 5 centimeters long and have the same diameter. The pericarpel is short, dark brown-green and shows some light-edged scales. Stamens, styles and stigma branches are white and the pollen is yellowish. The blue-green to whitish-green fruits are spherical, pear-shaped or spindle-shaped. They are up to 1.5 centimeters long and reach 1.2 centimeters in diameter. The seeds are 1.2 to 1.4 mm long and more or less spherical.

Taxonomy

The first description as Frailea bruchii was made in 1923 by Carlos Luis Spegazzini. The specific epithet bruchii honors the Argentine photographer and entomologist Carlos Bruch (1869–1943). Carl Curt Hosseus placed the species in the genus Gymnocalycium in 1926. A nomenclature synonym is Astrophytum bruchii (Speg.) Halda & Malina (2005).
