Gymnocalycium ponomarevae

A recently described chin cactus from northwestern Argentina with little published about it. Grow it like other lowland Gymnocalycium of the dry Chaco and Monte: bright but not scorching light, a warm, wet summer and a cool, dry winter.

Where it grows wild

Probably among shrubs and rocks in dry scrub of northwestern Argentina; species-specific habitat notes were not found, and many Gymnocalycium grow partly shaded by grasses and bushes.

No wild records; the measured point reads 293 m, which seems low for the region and may be misplaced.
