It is also a test site for the Hardy Fern Unmounted fern folded up (as received) Unmounted fern spread out for mounting. In most temperate-zone species of ferns, the rhizome is subterranean and has true roots attached to it. Fern leaves uncoil as they grow, thus initially resemble the top of a violin above the pegs (fiddlehead) or a shepherd’s or bishop’s staff (crozier). Turn over a fertile fern They are the sporangia of fern plants, found on the underside of their leaves, or fronds.

They are often found in shaded, damp forests in both temperate and tropical areas of the world, but many have adapted themselves to survive in a variety of environments. A sorus is a cluster of spore-producing receptacles called sporangia (blue and green) on the underside of a fern frond. The youtube clip below explains the fern life cycle. The young developing fronds show circinate vernation and thus are named as crozier or fiddlehead.

The Ferns are great additions to the Iowa shade garden. In older classifications these plants were informally divided into ‘true ferns’and ‘fern allies’. As a Boston fern has a less divided frond (pinnately compound) than the tree fern in the previous tutorial, this can be done in one step. The rhizoids and archegonia emerge from the underside off Bulblets are small vegetative buds that grow on the fronds of several fern species. Fronds can be simple and undivided like the leather leaf fern, or pinnate (once divided) like the thread fern. (G) Trachypteris pinnata, holodimorphic, with fern, (class Polypodiopsida), class of nonflowering, herbaceous vascular plants that possess true roots, stems, and complex leaves and that reproduce by spores.
