Abstract
Three new species of the fern genus Arachniodes (Dryopteridaceae) are described from Vietnam: A. daklakensis, A. longicaudata, and A. quangnamensis. The first two occur in Central Highlands and Central Vietnam, respectively, while the last is found in the north (Bavi, Langson and Tamdao) as well as in the central Vietnam (Nghean, Quangbinh, Quangtri).
