Line 20:
Many of them have linear frond segments, and some have sub-palmate division. Like other members of the [[Pteridales]], the frond margin is reflexed over the marginal sori.
The term "Brake", used for members of this genus, is a [[Middle English]] word for "fern" from southern England. Its derivation is unclear, and is generally thought to be related to "[[bracken]]", whereby the latter word has been assumed to be a plural, as with "children", and the former word a back-formation. However it may have a separate derivation.
