Propagation
Place spores on sterilised sphagnum moss, peat moss, bricks or terracotta pot base then cover with glass and keep moist. 4 to 6 weeks until prothalli appears. True fronds appear between 6-12 months after sowing. 

Division during the growing period, cut the rhizomes in to lengths and plant apex upwards, apply bottom heat and keep moist. 

Culture
When grown indoors Maiden Hair Ferns require a minimum night-time temperature of 10ºC (50ºF) and prefer high humidity around 60% which can be achieved with misting the surrounding air regularly. The plants do well in terrariums or placed in bathrooms in bright indirect light.

Re-pot only when necessary, as the plants prefer the roots to be crowded and water regularly during summer and reduce watering during winter. Do not allow the soil to become boggy.

Botanic information
Leaf: The tripinnate to quadripinnate broad-triangular fronds have a long shiny black stipe that extends to a zigzag rachis with alternate lesser rachises. The rhomboid pinnules are up to 20mm (¾in) long with a short petiole and the upper margin is serrated to lobed. 

Flower: The fertile fronds produce elongated reniform sori that are arranged on the lobes of the upper margin on the underside and are covered with a recurved marginal flap. They appear during autumn.

Fruit: This plant is normally reproduced vegetatively from rhizomes.

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 and dispersed by wind or water. The flowering and fruiting period may vary in tropical regions.
