Osmunda
a genus of perennial ferns of the family Osmundaceae. The stems are massive and usually short; they are topped by a crown of large leaves measuring as much as 3 m long. The pinnate leathery or filmy leaves are divided into vegetative and spore-bearing parts. Sometimes there are separate vegetative and spore-bearing leaves. There are about 15 species, growing in humid and swampy regions, primarily in the subtropics of Eurasia, Africa (including Madagascar), and the Americas. The USSR has three species. The royal fern (O. regalis), with leaves up to 1.5 m long, occurs in western Transcaucasia; the two other species are found in the Far East. Some species are ornamental.

No references found | The study found that Osmunda has the tobacco gene order, whereas the remaining taxa studied (a tree fern and several polypods) all had the Adiantum gene order, with no additional changes in structure detected. Osmunda regalis, the Royal Fern, was much loved by our Victorian and Edwardian forebears and is still a worthy garden plant for the bog garden or other permanently damp place and, unlike many ferns, will thrive in full sunshine, producing the typical flower spikes in mid to late summer. Orchid root media consists of bark or osmunda fiber, hinting at their dislike of standing or excessive water. |
