Gymnocalycium paraguayense is a species of Gymnocalycium from Paraguay.

Description

Gymnocalycium paraguayense grows as a solitary cactus with shiny green, flat, and later spherical stems, growing 5–8 cm in diameter, sometimes reaching 12 cm. It develops 7–12 ribs (rarely 5), divided by furrows with small chins beneath each bump. The cactus has 3–9 light brownish-yellow spines that turn light gray, measuring up to 3.5 cm, occasionally 6 cm. Its white, dioecious flowers feature a pale purple-pink throat, are up to 6 cm long and wide, and have green to olive-green pericarpels with scales tinged reddish at the tips. The green, pear-shaped fruits soften when ripe, containing oval seeds that are brown to black and 1–1.6 mm long.

Distribution

Native to Paraguay, it is found in Paraguarí, Cordillera, and the Chaco region at altitudes of 150 to 300 meters in partial shade.

Taxonomy

Discovered as Echinocactus paraguayensis by Karl Schumann in 1903, it was reclassified to Gymnocalycium by Carl Hosseus in 1939.
