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

Note:
This plant may be difficult to establish requiring a semi-shaded protected position and ample available nutrients during the growing period.

Botanic information
Leaf: The large glossy dark green bipinnate fronds are up to 1.5 m (5 ft) long by 400 mm (16 in) wide with a stipe up to 700 mm (28 in) long that is densely scaly and covered in downy hairs. 

The rachis is also densely covered with narrow scales and hairs and has 20 or more pairs of linear-lanceolate pinnae that are up to 250 mm (9¾ in) long by 40 mm (1⅝ in) wide. The ovoid-oblong to diamond-shape pinnules are up to 17 mm (⅝ in) long by 3 mm (⅛ in) wide with an obtuse to truncate apex and an entire or slightly serrated thickish margin.

Flower: The sterile fronds are similar to the fertile fronds that are dark green above and pale beneath. There are 1-6 broadly elliptical sori per pinnule and arranged in a row close to the upper margin. The brown peltate indusia are pale brown along the entire margins and appear during summer or sporadically throughout the year in tropical regions.

Fruit: The spores are produced in the sporangium during the sporophyte stage of the fern life cycle and appear in a row close to the margin on the underside of the fertile pinnules. The spores are very small (like fine dust) and are released from the sori when mature and dispersed by wind or water.
