Gymnocalycium hossei

Gymnocalycium hossei (Haage) A.Berger is a member of the Cactaceae family, known as the cactus family. It belongs to the genus Gymnocalycium, which includes small to medium-sized cacti native to South America. The species was formally described in 1929 by A. Berger, who reclassified it from its original authorship by Haage. This species is part of a diverse group of cacti characterized by their globular or columnar shapes and often showy flowers. The genus name 'Gymnocalycium' refers to the calyx structure of the flowers, which is typically exposed or 'naked' in these species.
