Tufted dwarf Ferns with pinnate fronds, of which the stipes are usually jointed above the base. Sori globose; indusium attached under the sorus, at first cup-shaped and entire, ultimately breaking up into filiform segments. There are 14 species described, from arctic and alpine regions. This genus is dedicated to Joseph Woods, an English botanist, author of the 'Tourist's Flora,' etc.

W. hyperborea and W. ilvensis are found in Britain at considerable elevations in Wales, North England and Scotland. In the first the ultimate lobes of the linear-lanceolate fronds are entire, and in the second they are crenate, and the frond is broadly lanceolate in outline.
