 The Ferns of West Virginia
Osmunda claytoniana is found in a wide variety of habitats throughout the state.
Osmunda regalis or the royal fern can be easily identified as it produces its fertile spores at the tip of its fronds.
Osmunda cinnamomea known as the cinnamon fern produces its spores on separate leaf blades arising from the center of the plant.

 Pteridophytes of Wisconsin: Osmunda claytoniana, interrupted fern
Osmunda claytoniana is a large fern with a conspicuously clumped growth form and fronds often approaching 1 meter in length (0.5-1.0).
Mature fertile fronds are unique in our flora, with several pairs of medium to dark brown fertile pinnae inserted along the length of a blade otherwise the same as a sterile frond.
Sterile plants of Osmunda claytoniana may be common under forest canopy, but can be recognized by the lack of a small area of wooly hairs on the under (abaxial) surface at the base of the pinnae, that is present on O.

 Osmunda regalis
Osmunda regalis is unusual in that it forms new fertile fronds in autumn, and not in spring or summer as is common in most ferns.
The stem was used as an astringent and a tonic.
Osmunda regalis requires a cold winter, and this is maybe the reason why, in southern Africa, this species tends not to form the massive plants (with fronds of up to 3.3 m in favourable conditions) seen in Europe.

 Hazen's Notch Association > Vermont Nature News™ > Plants > Osmunda claytoniana, cinnamomea, regalis
Osmundas like moist conditions and occur throughout Vermont in sunny wetlands, beaver meadows, roadside ditches, along streams where there is sufficient sunlight and at the edges of mowed areas.
We may first enjoy Osmundas in late April and through the month of May. The earliest Osmunda species to emerge is Interrupted Fern with rapidly expanding crosiers, or fiddleheads, that are covered with soft tan wool.
The tips of the most mature fronds abruptly change from green sterile pinnules, which make food for the plant, to contracted fertile pinnules with clusters of sori that mature from an initial color of green-purple to rusty brown when the mature spores are released by the wind.

Osmunda cinnamomea, has sterile outer fronds that are long and graceful, from a central crown, much like an Ostrich Fern.
Osmunda regalis, the Royal Fern, has a graceful, upright habit and large bold fronds, reddish when young.
The fertile portions are brown clusters held at the tips of the central fronds, vaguely flowerlike from a distance.

 Royal Fern
The generic name Osmunda is of Saxon origin and was one of the titles of the pagan deity Thor.
The royal fern belongs to the family Osmundaceae; fossils belonging to this family have been found in rocks of Permian age (230,000,000 years before present), a time when the continents were consolidated into the supercontinent Pangea.
Osmundas have witnessed the rise of the reptiles, the flourishing and eventual extinction of the dinosaurs, the origin and adaptive radiation of the mammals, and the rise to dominance of an obscure genus of hominids named Homo.

 Floridata: Osmunda regalis
Most kinds of ferns bear their reproductive spores on the underside of their leaves, but the osmunda ferns have their spores in clusters on specialized fronds.
Royal fern can be distinguished from the related cinnamon fern (Osmunda cinnamomea) by its bipinnate leaves, the fertile ones with clusters of sporangia towards the tips.
The fibrous roots (osmunda fibre) were formerly used as a medium for growing orchids and bromeliads.

 Floridata: Osmunda cinnamomea
Most ferns carry their reproductive spores on the undersides of the fronds; cinnamon fern (and other species of Osmunda) have separate and distinctive fertile fronds in addition to the typical sterile fronds.
There are about a dozen species of Osmunda, occurring on all continents except Australia.
The fibrous root masses of royal fern are the source of osmunda fiber, which is used as a potting medium for orchids and other epiphytes.
