Gymnocalycium quehlianum, the Quehla chin cactus, is a species of flowering plant in the family Cactaceae, native to northern Argentina.

Description

Gymnocalycium quehlianum typically grows as a solitary plant, although it can sometimes form groups. Its shoots are spherical to slightly flattened, displaying a grey-green color with reddish tinges. The plant can reach heights of up to 4 centimeters and diameters of 10 to 15 centimeters. It features 11 to 14 low ribs, which are separated by transverse furrows into rounded humps that have chin-like projections. The 5 to 7 thin, downward and outward-curving brown spines are white and can grow up to 1 centimeter long. In summer, the plant produces white daisy-like flowers with a reddish throat, measuring up to 6 centimeters in length. Its fruit is greyish-brown, slender, and club-shaped. ^[1] In cultivation, where temperatures fall below 10 °C (50 °F) it requires the protection of glass. ^[2] This plant has gained the Royal Horticultural Society's Award of Garden Merit. ^{[3] [4]}
