Asplenium antiquum 'Osaka' is a cultivar of Asplenium antiquum Makino. It is a slow-growing, epiphytic fern of the spleenwort family noted for foliage with very attractive wavy margins. Fronds spread upward and outward to form a vase-shaped, green rosette with a nest-like center; into which fallen leaves and other organic matter typically accumulate.; Undersides often display sori (clusters of sporangia) arranged in herringbone fashion in straight black lines from the central mid-rib to the frond margin. The 'Osaka' cultivar is a compact variety with truly wavy leaf margins.
