Gymnocalycium striglianum

Gymnocalycium striglianum is a species of cactus that typically grows individually. Its stems are characterized by their blue-green to brown to blackish-green color, and are flattened and spherical in shape. They can grow to a height of 3-5 centimeters and a diameter of 4-8 centimeters. The stems have 8-12 ribs. The plant's thorns are blackish-brown in color and can be up to 1.5 centimeters long. They may be flat against the stem's surface or protrude outwards, and some may have a slightly lighter tip. There are usually 3-5 thorns on each stem. Gymnocalycium striglianum produces small, funnel-shaped flowers with a creamy white base and a pink tint. These flowers can reach a length of up to 5 centimeters (occasionally longer, up to 8.5 centimeters) and a diameter of 4 centimeters (rarely up to 7.5 centimeters). The plant's fruits are small and spindle-shaped, typically growing up to 4 centimeters in length and 1 centimeter in diameter.

Gymnocalycium striglianum is commonly found in Argentina's San Luis and Mendoza provinces, at altitudes ranging from 600 to 1200 meters.
