Description[edit]

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.[2][3]

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.[2][3][4]

Preparations from the rhizomes of Drynaria roosii is used in traditional herbal medicine for aiding in the healing of bone fractures and for treating rheumatoid arthritis.[2][5]

Pharmacological study[edit]

Modern studies of Drynaria roosii have identified in vitro effects on isolated bone cells.[6]

Flavan-3-ols and propelargonidins can be isolated from the rhizomes.[7]
