Family 2. OSMUNDACEAE R. Br. Prodr, Fl. Nov. Holl. 1: 161. 1810. 
ROYAL FERN FAMILY. 
Large ferns with stout often erect rootstocks, 1-2 pinnate leaves coiled in 
vernation, the veins free, mostly forked, running to the margins of the pin- 
nules or lobes. Sporanges large, globose, with mere traces of an elastic ring of 
cells or none, borne on modified contracted pinnae in the typical genus; in 
Todea, a genus of the southern_hemisphere, in clusters (sori) on the lower sur- 
faces of the pinnules. : 
Two living genera, Osmunda and Todea.
