Asplenium hybridum

Dalmatian spleenwort

A rare spleenwort of the Kvarner islands in Croatia, all of whose GBIF records come from there. It is accepted as a species and has long been treated as of hybrid origin, hence the name. Its home has a mild Mediterranean coastal climate, with warm dry-ish summers and cool, very wet winters.

Where it grows wild

Grows in crevices of limestone rock and old walls near the sea, as the related rock spleenworts of the Kvarner coast do. This is inferred from the coastal, low-elevation records and from related species, not from a species account.

Records lie at 8–30 m, near sea level (4 records).
