Asplenium dodecaploideum

A member of the Asplenium aethiopicum complex, first treated by Braithwaite as a dodecaploid subspecies and raised to species by Viane in 2021. It ranges across southern and south-central Africa and the Comoros; relatives in this complex are tough ferns of rock crevices and forest margins with a dry winter.

Where it grows wild

By analogy with the A. aethiopicum complex, it grows in rock crevices, boulder bases and shaded forest edges on the plateau and escarpments. Species-specific habitat notes were not reachable.

Climate sites lie at about 1180–2420 m; GBIF has no wild records under this name.
