Blechnum pampasicum

A little-documented Blechnum known from only a handful of wild records in the Sierras of Córdoba, central Argentina. Treat it as a hardy, seasonally dry-climate fern of sheltered rocky ravines: warm moist summers, cool nights and a drier, cooler winter.

Where it grows wild

Recorded from the hills of Córdoba province, where a fern almost certainly grows in shaded stream banks, rock crevices and ravines rather than the open dry scrub the regional climate describes. Species-specific habitat notes were not found.

Sites at roughly 400–1150 m in the Córdoba sierras; few records carry an elevation.
