Propagation
Divide rhizomes in to lengths during growing period.

Place spores on sterilised sphagnum or peat moss then cover with glass, keep moist for 4 to 6 weeks maintaining a temperature of 16ş C (61ş F), with indirect light.
Cleanliness is essential during the propagation process.

Botanic information
Leaf: The dark green pinnate fronds have 4-wedged-shaped pinnae that are up to 50 mm (2 in) long by 40 mm (1? in) wide and are notched (dentate) on the outer edge. They have an orbicular-like appearance and are arranged in a cluster from the base. The upper surface has 2-different green colours that are separated by a brown band and the underside may be pubescent towards the base. The slender brown stipe is normally 300 mm (1 ft) long but can extend up to 900mm (3 ft).

Flower: The spores are produced in a sporocarp that is attached to the rhizome on a branched pedicle at the base of the petiole. This unusual fern produces micro and macro spores that form male and female prothallus and appear during summer.

Fruit: The spores are produced in solitary hard sporocarps and mounted on short 1-3 branched peduncle. The fruit was commonly collected by the Australian Aboriginals as a source of food. This plant is normally reproduced vegetatively.
