1-3 Dennastaedtiaceae, bracken family

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

Abstract



Although the family once included most of the ferns, it is now restricted to those ferns with their sori at or near the margins of the pinnae. Indusia are present and may be one of two types. The outer is a false indusium formed of the inrolled margins and the inner indusium, is the true indusium. Stipes and blades are pubescent, scales are usually absent. Rhizomes are long-trailing. Photographs by Sean Blaney and David Mazerolle.
