Asplenium is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider Hymenasplenium separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is Asplenium marinum.
Pteris (brake) is a genus of about 300 species of ferns in the subfamily Pteridoideae of the family Pteridaceae. They are native to tropical and subtropical regions, southward to New Zealand, Australia, and South Africa, north to Japan and North America. 78 species are found in China. Some species of Pteris have considerable economic and ecological value, such as Pteris multifida, Pteris ensiformis, Pteris vittata can be used for ornamental purposes; as a hyperaccumulator, Pteris multifida and Pteris vittata can be used to control soil pollution.
Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
Pteridaceae is a family of ferns in the order Polypodiales, including some 1150 known species in ca 45 genera, divided over five subfamilies. The family includes four groups of genera that are sometimes recognized as separate families: the adiantoid, cheilanthoid, pteridoid, and hemionitidoid ferns. Relationships among these groups remain unclear, and although some recent genetic analyses of the Pteridales suggest that neither the family Pteridaceae nor the major groups within it are all monophyletic, as yet these analyses are insufficiently comprehensive and robust to provide good support for a revision of the order at the family level.
Ceratopteris thalictroides is a fern species belonging to the genus Ceratopteris, one of only two genera of the subfamily Parkerioideae of the family Pteridaceae.
Ceratopteris is the only genus among homosporous ferns that is exclusively aquatic. It is pan-tropical and classified in the Parkerioideae subfamily of the family Pteridaceae.
Mutisia is a genus of flowering plant in the tribe Mutisieae within the family Asteraceae. Mutisia has been named after José Celestino Mutis. It comprises about sixty species which can be found along the entire length of the Andes and in southern Brazil, Paraguay, Uruguay and northern Argentina.
Bolbitis is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016.
Pecluma is a genus of ferns in the family Polypodiaceae, subfamily Polypodioideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). They are called rockcap ferns.
Hypolepis (beadfern) is a genus of ferns described as a genus in 1806. The word is derived from Greek, meaning "under scale". It is found in tropical and subtropical regions, primarily in the New World but also in the Old World and on various oceanic islands.
Coniogramme is one of three genera in the subfamily Cryptogrammoideae of the fern family Pteridaceae. A cultivated species, Coniogramme pilosa, is known as "bamboo fern."
Ceratopteris richardii is a fern species belonging to the genus Ceratopteris, one of only two genera of the subfamily Parkerioideae of the family Pteridaceae. It is one of several genera of ferns adapted to an aquatic existence. C. richardii was previously regarded as being part of the species Ceratopteris thalictroides.
Acrostichum is a fern genus in the Parkerioideae subfamily of the Pteridaceae. It was one of the original pteridophyte genera delineated by Linnaeus. It was originally drawn very broadly, including all ferns that had sori apparently "acrostichoid", or distributed in a uniform mass across the back of the frond, rather than organized in discrete sori. This led Linnaeus to include such species as Asplenium platyneuron in the genus, because the specimen he received had sori so crowded that it appeared acrostichoid.
Angiopteris evecta, commonly known as the king fern, giant fern, elephant fern, oriental vessel fern, Madagascar tree fern, or mule's foot fern, is a very large rainforest fern in the family Marattiaceae native to most parts of Southeast Asia and Oceania. It has a history dating back about 300 million years, and is believed to have the longest fronds of any fern in the world.
Pyrrosia is a genus of about 100 fern species in the polypod family, Polypodiaceae. Like other species in Polypodiaceae, the species of Pyrrosia are generally epiphytic on trees or rocks, a few species are terrestrial. The Latin name of Pyrrosia comes from the Greek pyrrhos (red), which refers to its leaves that are red due to the sporangia.
Pityrogramma, the silverback ferns, or goldback ferns, is a fern genus in the subfamily Pteridoideae of the family Pteridaceae.
Palhinhaea is a genus of lycophytes in the family Lycopodiaceae. In the Pteridophyte Phylogeny Group classification of 2016, it is placed in the subfamily Lycopodielloideae. Some sources do not recognize the genus, sinking it into Lycopodiella. Palhinhaea species are widespread in the tropics and subtropics.
Austroblechnum is a genus of ferns in the family Blechnaceae, subfamily Blechnoideae, according to the Pteridophyte Phylogeny Group classification of 2016. The genus is accepted in a 2016 classification of the family Blechnaceae, but other sources sink it into a very broadly defined Blechnum, equivalent to the whole of the PPG I subfamily.
Austroblechnum lehmannii is a species of fern in the family Blechnaceae. It is native to Mexico, Central America, South America and the Galápagos Islands.
