Polystichum

The genus Polystichum includes, but is not limited to, the following species.

Polystichum bulbiferum is a species of fern in the Dryopteridaceae family.

Polystichum setiferum is frequently cultivated as an ornamental plant for use in gardens.

The Polystichum dudleyi fern produces several arching leaves up to a meter-3 feet long.

The Polystichum aleuticum fern is described as erect and approximately six inches tall.

This fern arose as a hybrid between other Polystichum species and readily forms hybrids of its own.

Polystichum is a genus of about 260 species of ferns with a cosmopolitan distribution.

Species that were at one time considered part of the Polystichum genus, but are now categorized elsewhere, include:

Polystichum californicum is a species of fern known by the common name California sword fern.

Polystichum bulbiferum.

Polystichum bonapartii.

Polystichum proliferum is an Australian fern.

Polystichum acrostichoides var.

Polystichum richardii, common shield fern.

Polystichum aleuticum, the Aleutian Shield Fern, may be the least known of all the world's ferns as there is little information available.

Polystichum richardii, commonly known as the common shield fern, or pikopiko is fern found in New Zealand.

Polystichum setiferum (soft shield fern) is an evergreen or semi-evergreen fern native to southern and western Europe.

Polystichum setiferum, Athyrium filix-femina, and Asplenium scolopendrium, for example, each yielded about three hundred different varieties.

Polystichum tsus-simense, commonly known as the Korean rock fern is a perennial herbaceous plant native to East Asia.

Polystichum aculeatum (Hard Shield Fern) is an evergreen fern native to Europe.

It is very closely related to the genus Polystichum, with recent research suggesting it should be included within it (Little & Barrington).

Polystichum vestitum, commonly known as the Prickly Shield Fern, is a hardy, evergreen or semi-evergreen ground fern.

Polystichum vestitum is a terrestrial fern with an erect and scaly rhizome, sometimes forming a short trunk and growing up to 700 mm in height.

It is unlike any other known shield fern found in North America, and originally it was questioned whether it even belonged to the Polystichum genus.

Like other ferns of the genus Polystichum, it is allied to the wood ferns, genus Dryopteris, which it often is found growing close to.
