Xyropteris stortii, monotypic

Tapeinidium pinnatum

Odontosoria gymnogrammoides Lindsaeaceae image

Sphenomeris chinensis - Lace fern. Hawaiians made red-brown dye from the old fronds. Pala'ā was used to treat "female ailments". It is made into a lei using the hili, or hilo technique - a braiding or plaiting method with only one type of plant material. Philippines dry and boil the plant in fresh water until the water turns dark brown to complete black. They consider it as a herbal tea for various health benefits such as better stamina and relief from fatigue.

Lonchitis hirsuta. Lonchitis is a neotropical genus of ferns. It is the sole genus in the family Lonchitidaceae. In Smith et al. (2006) Lonchitis was placed in Lindsaeaceae, before being placed in its own family.

Lindsaea microphylla - Lacy wedge fern. The common name for Lindsaea is neclase ferns.

Cystodium sorbifolium - The only species in the genus. Used to be placed in the tree ferns.

Matoniaceae: Matonia pectinata

Matoniaceae: Phanerosorus sarmentosus

Dipteridaceae: Cheiropleuria bicuspis.

Dipteridaceae: Dipteris conjugata

Gleicheniaceae: Gleichenia dicarpa - Pouched coral fern

Gleicheniaceae: Diplopterygium bancroftii

Gleicheniaceae: Dicranopteris linearis - Old World forked fern. As a pioneer species in ecological succession, it can colonize bare sites such as lava flows. When the fern grows onto a new site it produces layers of stems and leaves repeatedly until there is a network of vegetation. The network then fills with organic forest detritus, forming a litter layer which can be a meter thick. The fern may have allelopathic effects, preventing the growth of other plants.

Gleicheniaceae: Sticherus flabellatus - Shiny fan fern. In Australia Sticherus-ferns are commonly referred to as shield ferns, In the United States as umbrella ferns.

Gleicheniaceae: Gleichenella pectinata

Gleicheniaceae: Stromatopteris moniliformis - the only species of the genus Stromatopteris.

Salciniaceae: Salvinia molesta - Rikkakellusanianen / Giant salvinia ) is a commonly introduced invasive weed in warm climates. It grows rapidly and forms dense mats over still waters. Leaf development in Salvinia (watermosses) is unique. The upper side of the floating leaf, which appears to face the stem axis, is morphologically abaxial.

Salciniaceae: Azolla pinnata - mosquitofern. They form a symbiotic relationship with the cyanobacterium Anabaena azollae, which fixes atmospheric nitrogen, giving the plant access to the essential nutrient. The nitrogen-fixing capability of Azolla has led to Azolla being widely used as a biofertilizer. Azolla is also used in bioremedies and as a livestock feed.

Marsileaceae: Pilularia globulifera - Ormio / Pillwort

Marsileaceae: Regnellidium diphyllum - two lead water fern. Only extant member of the family Regnellidium. It is the only non-flowering plant that produces latex.

Marsileaceae: Marsilea quadrifolia - Apilasanianen / European waterclover. In some places it has been used as food and medicine for more than 3000 years. Leaves of this fern have sometimes been used to substitute for clover leaves on Saint Patrick's Day.

Schizaeceae: Schizaea pectinata - Toothbrush fern

Schizaeceae: Actinostachys laevigata

Anemiaceae: Anemia mexicana - Mexican flowering fern

Lygodiaceae: Lygopodium japonicum - Japanese climbing fern, was added to the Florida Noxious Weed List in 1999, causing problems in pine plantations. Lygodiaceae-ferns are unusual in that the rachis, or midrib, of the frond is thin, flexible, and long, the frond unrolling with indeterminate growth and the rachis twining around supports, so that each frond forms a distinct vine.

Trichomanes petersii - Dwarf bristle fern. The name bristle fern refers to the small bristle that protrudes from the indusia of these ferns. (In the article divided to nine genera (Ebihara & al, 2006), two major clades (Pryer & al, 2001b), "trichomanoid" and "hymenophylloid", roughly corresponding to the classical genera Trichomanes s.l. and Hymenophyllum)

Kuvahaun tulos haulle hymenophyllum wilsonii

Todea barbara - king fern. Grows readily in gardens in temperate or subtropical climates.

Leptopteris superba - Prince of Wales feather

Osmunda regalis - kuningassaniainen / royal fern. Because of the large mass of sporangia that ripen uniformly at the same time to a showy golden color, the ferns look as if they are in flower, and so Osmunda is sometimes called the "flowering ferns".

Marattia howeana - king fern. Marattia is recognized by sessile, bivalved synangia. In more recent literature, Marattia was segregated into three genera Eupodium, Ptisana and Marattia.

Danaea nodosa

Christensenia aesculifolia. Christensenia produces enormous amounts of spores, up to 7,000 spores per sporangium. The presence of a radial synangium is an archaic character.

Angiopteris evecta - giant fern. The species name is the Latin adjective evectus "swollen", probably a reference to its huge, bulbous pulvini. Angiopteris is unique among ferns in having explosively dispersed spores, thought to be caused by the cavitation of an airspace between spore layers.

Equisetum sylvaticum - Metsäkorte / wood horsetail. The name Equisetum (horsetail, snake grass, puzzlegrass) is derived from the Latin equus ("horse") + seta ("bristle"). Equisetaceae is the only surviving family of the Equisetales, a group with many fossils of large tree-like plants that possessed ribbed stems similar to modern horsetails.

Tmesipteris ovata - oval fork-fern. Tmesipteris (hanging fork-ferns) can often be found with lighter bag-like sporangia at the bases of some of their "leaves". The plants possess no true leaves; what appear to be leaves are flattened stems.

Psilotum nudum - whisk fern. Its name means "bare naked" in Latin, because it lacks most of the organs of typical vascular plants, as a result of evolutionary reduction. Called matsubaran ("pine-needle orchid") in Japanese, it was one of the noble plants in the Edo period, with many varieties. Psilotum - whisk ferns

Helminthostachys zeylanica - flowering fern. Roots are popular in Chinese medicine.

Mankyua chejuense - recently discovered plant, a single species in its own genus. It grows only on Cheju Island of South Korea. While this plant is clearly ophioglossoid in the broad sense, its precise cladistic position is uncertain.

Ophioglossum reticulatum - notable for having as many as 1260 chromosomes. Young fronds are commonly eaten as a salad or vegetable with a sweet flavor. Ophiloglossum: adder's-tongue ferns

Botrychium lunaria - Ketonoidanlukko (common moonwort) there are a few members of Botrychium that are unique among ferns in having the sporophytes also mycoheterotrophic, producing only small, ephemeral sporophylls that do not photosynthesize. - Botrychium: noidanlukot/moonworts; grapeferns
