Drynaria roosii
Drynaria roosii, commonly known as gu-sui-bu, is a species of basket fern of the family Polypodiaceae. The plant is native to Eastern Asia, including eastern China.
It is used in traditional Chinese medicine. This species is also more frequently cited by Asian studies by its synonym, Drynaria fortunei; however, this is an illegitimate name.

Description
Drynaria roosii is an epiphytic (growing on trees) or epipetric (growing on rocks) plant. Like other species of Drynaria, they possess two frond types – a fertile foliage frond and a sterile nest frond. Sterile nest fronds are rounded shallowly-lobed reddish-brown fronds overlapping each other. They bear no sori and form a 'basket' characteristic of the genus. The fertile fronds are larger and deeply lobed. They bear 1 to 3 sori arranged on both sides of the central rib.
