Cryptogramma cascadensis

Cryptogramma cascadensis is a species of fern known by the common names Cascade parsley fern and Cascade rockbrake.

Contents

Description

The plant forms a clump from a rhizome. It has two types of leaves. The sterile leaf is flat with lobed oval or diamond-shaped leaflets, and the fertile leaf is longer, with narrow, thick, fingerlike leaflets with edges curled under to cover the sporangia on the undersides. The leaves are deciduous. [1]

Taxonomy

Formerly lumped with Cryptogramma acrostichoides , C. cascadensis was described as a distinct species by Ed Alverson in 1989. The type specimen was collected growing on talus below Chair Peak, 5 km (3 mi) northwest of Snoqualmie Pass. [2]

Distribution and habitat

It is native to western North America from British Columbia to Montana to California, where it grows in the cracks and crevices of mountain talus slopes, especially in moist subalpine areas on volcanic or granite rocks.

Marsileaceae is a small family of heterosporous aquatic and semi-aquatic ferns, though at first sight they do not physically resemble other ferns. The group is commonly known as the "pepperwort family" or as the "water-clover family" because the leaves of the genus Marsilea superficially resemble the leaves of a four-leaf clover. In all, the family contains 3 genera and 50 to 80 species with most of those belonging to Marsilea.

<i>Dryopteris marginalis</i> Species of fern

Dryopteris marginalis, vernacularly known as the marginal shield fern or marginal wood fern, is a perennial species of fern found in damp shady areas throughout eastern North America, from Texas to Minnesota and Newfoundland. It favors moderately acid to circumneutral soils in cooler areas but is fairly drought-resistant once established. In the warmer parts of its range, it is most likely to be found on north-facing non-calcareous rock faces. It is common in many altitudes throughout its range, from high ledges to rocky slopes and stream banks. Marginal wood fern's name derives from the fact that the sori are located on the margins, or edges of the leaflets.

Achlys is a small genus of flowering plants in the barberry family (Berberidaceae), which it shares with genera such as Berberis and Vancouveria. It is named after the Greek legendary figure associated with shade and mist, Achlys, because the plants grow in the shade.

<i>Cryptogramma</i> Genus of ferns

Cryptogramma is a genus of ferns known commonly as rockbrakes or parsley ferns. They are one of the three genera in the Cryptogrammoideae subfamily of the Pteridaceae. Cryptogramma ferns can be found in temperate regions on several continents worldwide. These ferns have two kinds of leaves which often look so different that at first glance they appear to belong to different plants. The fertile leaves have long, narrow, bumpy segments with undersides covered thickly in sporangia. The edges of the segments may curl back to cover the sporangia, forming a false indusium. The sterile leaves have thinner, wider segments which may be rounded and resemble the leaves of parsley. These ferns grow in rocky areas, often in crevices and cracks.

These finger-like segments are not individual leaves, but parts of a single compound leaf. The "fingers" may be drooping or erect, depending on whether the individual fern grows in shade or sunlight. Spores are borne under false indusia at the edge of the subdivisions of the leaf, a characteristic unique to the genus Adiantum.
