[edit] Habitat and distribution

Pteris vittata is often associated with limestone habitats. It may be seen growing on concrete structures and cracks, in buildings in the central business district and suburbs of SydneyAustralia.[4][5]
Pteris vittata is native and wide spread in the paleotropics: found from the east, to the south tropical, and southern Africa (in AngolaKenyaLesothoMalawi;MozambiqueNamibiaTanzania (including the Zanzibar Archipelago); Cape ProvinceFree StateKwaZulu-Natal, and Transvaal in South AfricaSwaziland;UgandaZambia; and Zimbabwe); temperate and tropical Asia (in the provinces of AnhuiGansuGuangdongGuangxiGuizhouHubeiJiangxiSichuanXizang, and Yunnan in China; the prefectures of HonshuKyushuShikoku, and the Ryukyu Islands of Japan; and Thailand); and Australia, in the states of New South Wales,[4] QueenslandVictoria, and Western Australia.[3]
It is an introduced species in CaliforniaTexas, and the Southeastern United States[6]

[edit] Uses

Although it grows readily in the wild, Pteris vittata is sometimes cultivated.[3] It is grown in gardens for its attractive appearance,[3] or used in pollution controlschemes:[3] it is known to be a hyperaccumulator plant of arsenic used in phytoremediation[7]
