Aglaomorpha fortunei

Aglaomorpha fortunei, 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, the correct name in the genus "Drynaria" being Drynaria roosii.
Description.
"Aglaomorpha fortunei" is an epiphytic (growing on trees) or epipetric (growing on rocks) plant. Like other species of "Aglaomorpha", 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.
Taxonomy.
The species was first described in 1856 as "Polypodium fortunei", with the name attributed to Gustav Kunze. In 1857, J. Smith transferred the species to the genus "Drynaria", using the name "Drynaria fortunei". However, although widely used, this is an illegitimate name, because it had been published in 1855 for a different species. In 1992, Toshiyuki Nakaike published the replacement name, "Drynaria roosii", which is the correct name for the species if placed in the genus "Drynaria".
In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the genus "Aglaomorpha" is placed in the subfamily Drynarioideae of the family Polypodiaceae.
Medicinal uses.
Preparations from the rhizomes of "Aglaomorpha fortunei" are used in traditional herbal medicine for aiding in the healing of bone fractures and for treating rheumatoid arthritis.
Pharmacological study.
Modern studies of "Aglaomorpha fortunei" have identified "in vitro" effects on isolated bone cells.
Flavan-3-ols and propelargonidins can be isolated from the rhizomes.
