3 Cliff Brakes. Pellàea
Sporangia borne on the upper part of the free veins inside the margins, in dot-like masses, but may run together, as in the continuous fruiting line of the bracken. Indusium formed of the reflexed margins of the fertile segments which are more or less membranous. (Pellæa, from the Greek pellos, meaning dusky, in allusion to the dark stipes.)
