Hypodematiaceae

Broad, finely divided, hairy fronds growing in a spreading crown from a stout, densely scaly rhizome; round spore clusters on the frond underside are each covered by a small, often hairy, kidney-shaped flap.

As true ferns this family has no flowers or seeds — its densely hairy rhizome scales and fronds distinguish it from otherwise similar wood-fern relatives.

To check whether a plant belongs to Hypodematiaceae, compare the leaf arrangement, leaf type, flower symmetry, fruit type, and one distinctive marker together. A single feature can mislead; the family pattern is the combination.
