Propagation
Offset may be separated from parent plants and tied to host with added peat moss and leaf mould.

Divide rhizomes in to lengths and plant upward with bottom heat and keep moist during growing period.

Spore Sowing: Place spores on sterilised sphagnum moss, peat moss, cover with glass and keep moist. 4 to 6 weeks. Prothalli will appear.


Botanic information
Leaf: The nest leaves are wedged shape and deeply lobed up to 300 mm (1 ft) wide laying flat across the root system. The pendant fertile fronds appear from a central point of the sterile fronds and are up to 1 m (3 ft) long and are divided once or twice into narrow lobes (elk-like).

Note
The 'nest leaves'have a spongy central area and become thinner towards the edges.
As these leaves die off they form a peaty moist base were other organic mater collects and decomposes and funnel water towards the roots that are attached to the host.

Flower: The sporangia appear on the tips on the underside of the pendant fertile fronds like a thick brownish blanket during late summer.

Fruit: The spores are produced in the sporangium during the sporophyte stage of the fern life cycle in rows on the back of the fertile frond. The spores are very small (like fine dust) and are released from the sori when mature.
