1-9 Osmundaceae, royal fern

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

Abstract


A family of large coarse plants, these are our largest pteridophyte species. Stipes arise from rhizomes covered in persistent frond bases. Stipes are pubescent but without scales, bearing stipules at their bases. Fertile fronds may be separate from vegetative fronds, or fronds divided between sterile and fertile portions. Sporangia are not arranged in sori, but in short stalked clusters.Three species in a single genus are found in Nova Scotia. Image use provided by Sean Blaney, David Mazerolle and Beth Cameron.
