Tephrocactus abditus

A small, segmented Tephrocactus from northwestern Argentina, known from very few records. Like the rest of the genus it is a full-sun, cold-tolerant dwarf cactus of dry Andean foothills that wants a hot, bright summer with rain and a dry, cool winter.

Where it grows wild

No habitat detail was reachable; Tephrocactus typically grows in open, stony or gravelly ground among sparse shrubs on dry slopes of the Andean foothills and puna edge.

The climate site sits near 300 m, but the genus usually grows from about 1,000 to over 3,000 m, so real populations are likely much higher and cooler.
