Many of them have linear frond segments, and some have sub-palmate division. Like other members of the Pteridaceae, 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.[2]

Cultivation and uses
Some of these ferns are popular in cultivation as houseplants. These smaller species are often called "table ferns".
Pteris vittata (commonly known as brake fern) was discovered to have the ability to "hyperaccumulate" (absorb large amounts of) arsenic from soil. The fern was growing at a central Florida site contaminated with large amounts of copper arsenate in the soil. Dr. Lena Q. Ma of the University of Florida later discovered that it had hyperaccumulated considerable amounts of arsenic from the soil. The discovery may lead to the use of pteris vittata as a potential bioremediation plant. [1]
