Stiff, leathery, once-divided fronds, often producing two visibly different frond types on the same plant — sterile, spreading fronds for photosynthesis and narrower, upright fertile fronds specialised for bearing spores.
As true ferns this family has no flowers or seeds — the clear split between separate sterile and fertile frond shapes on the same plant is a distinctive, easy-to-spot field mark.
