Wikipedia 설명
Pteris vittata, commonly known variously as the Chinese brake,[3] Chinese ladder brake,[3] or simply ladder brake,[3] is a fern species in the Pteridoideae subfamily of the Pteridaceae.[4] It is indigenous to Asia, southern Europe, tropical Africa and Australia.[3] The type specimen was collected in China by Pehr Osbeck.[1]
Habitat and distribution
Pteris vittata is native and widespread in the paleotropics: found from the east, to the south tropical, and southern Africa (in Angola; Kenya; Lesotho; Malawi; Mozambique; Namibia; Tanzania (including the Zanzibar Archipelago); Cape Province, Free State, KwaZulu-Natal, and Transvaal in South Africa; Eswatini; Uganda; Zambia; and Zimbabwe); temperate and tropical Asia (in the provinces of Anhui, Gansu, Guangdong, Guangxi, Guizhou, Hubei, Jiangxi, Sichuan, Xizang, and Yunnan in China; the prefectures of Honshu, Kyushu, Shikoku, and the Ryukyu Islands of Japan; and Thailand); and Australia, in the states of New South Wales,[5] Queensland, Victoria, and Western Australia.[3]
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 Sydney, Australia.[5][6] It is an introduced species in California, Texas, and the Southeastern United States.[7]
A remnant population exists in the Italian peninsula, in Sicily, Calabria and Campania.[8]
