Plant description

Fern with very short rhizome and few clustered fronds on wiry black stems, to 50 cm long, at first erect but becoming prostrate. Fronds pinnate with lamina distinctive fan-shaped, pale green, outer margin toothed. Tip of fronds often without pinnae, sometimes taking root and producing plantlets.  Fruits are sori (spores) on the underside of the fronds, linear-oblong in middle of pinnae, not reaching margin. 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.
