Cinnamon fern [ Osmunda cinnamomea ] is named for the cinnamon-colored sporangia on its fertile fronds, which have no green leaves at all. Fern sporophytes are composed of megaphylls, often pinnately compound fronds that emerging as fiddleheads in the spring. Sporangia are produced in clusters called sori (sorus, singular) on the fronds. Figure \(\PageIndex{6}\): Anatomy of a fern. The fern frond (D) is emerging from an underground, horizontal stem called a rhizome (C). the Figures in this paper are of Y orkshire fern rust specimens, and the material was prepared fr om herbarium specimens (some very old) as described in Preece & Hick (1989).

Groups of sporangia called sori form on the underside of fern fronds. Sporangia Small, evergreen fern with clustered fronds. Habitat, Crevices or rough rock surfaces of Pottsville sandstone.

Ferns are not flowering plants; they reproduce by spores which are microscopic pollen-grain like bits of plant tissue. Spores form inside tiny thin-walled sacs called sporangia. The sporangia of sword fern cluster in brown dot-like structures called “sori” (singular “soros”), which line the back of each leaflet of the frond.

Mature fern spores are released and distributed on air currents, and those few spores that find suitable shady, moist habitat give rise to the alternate phase of the fern’s life cycle – an inconspicuous plant called a Royal fern (Osmunda regalis) is one of the types of ferns people use as planting mediums for popular flowers, such as orchids. This fern lives near the rivers and bogs with acidic soil, particularly in Asia, Europe, and Africa. Royal fern’s sterile fronds grow in flower-like spreads, which can reach 12 to 16 inches (30-40 cm) broad. the sori are circular or kidney-shaped the leaflets from the middle of the frond Leaflet stalks the leaflets are stalked Christmas fern.
