GENUS INDEX

GENUS CODE: WOODS
GENUS SCIENTIFIC: Woodsia
GENUS AUTHORITY: R. Br.
GENUS COMMON: Cliff fern
GENUS SUMMARY: A genus of about 30-38 species, of temperate and cool-temperate regions, widespread in the Northern Hemisphere, in montane tropical South America and Africa.
GENUS IDENTIFICATION: Identification notes: Woodsia species and Cystopteris species are all small ferns with thin-textured leaves, occurring primarily on or near rock outcrops; they frequently occur together or in proximity to one another and are often confused. Woodsia has the indusium divided into a series of scale-like or hair-like structures, attached below the sorus; Cystopteris has an undivided indusium, pocket-like or hood-like, attached around one side of the sorus. Woodsia has persistent dark petiole bases; in Cystopteris the petiole bases are deciduous. Woodsia has the final veinlets not reaching the margin; Cystopteris veins do reach the margin.
