Plant description

Delicate-looking, drooping fern with distinctive fan-shaped leaf segments and clustered fronds on wiry black stems. It spreads by means of short, creeping rhizomes covered in small brown scales, which sometimes appear reddish-brown or golden. The fronds are arching and hairless, occasionally with a bluish-green or waxy tinge to the usually pale-green leaves, which are pinnate, with individual leaflets often lobed or toothed along the margins. Fruits are sori (spores) on the underside margins of the fronds between the lobes. Seeds are very fine spores.

Seed collection and propagation

Look under the fronds and collect ones with spores and place in a seal paper bags to prevent spores from fulling out. Leave fronds in the paper bag to dry. The spores will fall off naturally or give the fronds a gentle shake. Use a very fine sieve to separate any unwanted material. Be careful as the spores are very fine. Store spores in an air tight container in a cool and dry place or in a -20oC freezer.
