Deuterocohnia haumanii

A small, spiny, clump-forming terrestrial bromeliad of dry rocky slopes in northwestern Argentina. It wants full sun, a fast-draining mineral mix, summer water and a dry, cool winter, much like a hardy Dyckia.

Where it grows wild

Like other Deuterocohnia, it presumably forms dense cushions of stiff rosettes among rocks on dry, open slopes in the subandean scrub; species-specific habitat notes were not found.

The few elevation records lie between 1400 and 1900 m, median about 1650 m.
