Arachniodes

Arachniodes is a fern genus in the family Dryopteridaceae (wood ferns), subfamily Dryopteridoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). A number of species in this genus are known as "holly ferns".

The genus Arachniodes was first published by Carl Ludwig von Blume in 1828, with the single Indonesian species Arachniodes aspidioides. The genus was not widely recognized until Mary Douglas Tindale transferred the two species (Byrsopteris amabilis and Byrsopteris aristata) into it in 1961.
