Pteris Brevis

''Pteris'' (brake) is a genus of about 300 species of ferns in the subfamily Pteridoideae of the family Pteridaceae. They are native to tropical and subtropical regions, southward to New Zealand, Australia, and South Africa, north to Japan and North America. 78 species (35 endemic) are found in China. Some species of ''Pteris'' have considerable economic and ecological value, such as ''Pteris multifida'', ''Pteris ensiformis'', ''Pteris vittata'' can be used for ornamental purposes; as a hyperaccumulator, ''Pteris multifida'' and ''Pteris vittata'' can be used to control soil pollution.

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 outermost layer is the single layered epidermis without stomata. The cortex is differentiated into outer and inner cortical region. The vascular cylinder is an amphiphloic siphonostele.

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.

The Latin genus name ''Pteris'' refers to the Greek name for fern (also meaning feathery).D. Gledhill

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.
