1-2 Blechnaceae, chain fern family

Marian C. Munro, Ruth E. Newell, Nicholas M. Hill


Mostly distributed in the south–temperate and tropical zones, 250 species in 10 genera belong here. NS has a single genus of coarse ferns. Rhizomes and stipes bear scales at least at the base. Blades may be reddish when young, and are also once or twice-pinnate. The veins remain separate on the sterile fronds and join to form the sori–bearing secondary veins, on the fertile fronds. Sori are elongated; indusia are present. Spores are kidney–shaped. Photographs by David Mazerolle and Alain Belliveau.
