Adiantum lunulatum

Walking maidenhair fern

A name widely used for the walking maidenhair, now usually treated as Adiantum philippense: a creeping or semi-erect fern with arching, tufted fronds that grows on stream banks and rocks in tropical forest and woodland. It is widespread in the Old World tropics, and GBIF records under this name also come from Central America. Most sites are seasonally dry, so it takes a drier rest well.
