Phlegmariurus is a genus of lycophyte plants in the family Lycopodiaceae. [1] The genus is recognized in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), [2] but not by some other sources, which keep it in a broadly defined Huperzia .

Taxonomy

The genus was first described in 1909 by Wilhelm Herter as the section Phlegmariurus of the genus Lycopodium . The section was elevated to a genus by Josef Ludwig Holub in 1964. [3]

Within the family Lycopodiaceae, Phlegmariurus is placed in the subfamily Huperzioideae. A phylogenetic study in 2016, employing both molecular and morphological data, concluded that either a one-genus or a three-genus division of the subfamily produced monophyletic taxa. The authors preferred the three-genus division, recognizing Huperzia , Phlegmariurus and Phylloglossum . Their preferred hypothesis for the relationships of the three genera was: [4]

Huperzioideae

Phylloglossum

Huperzia

Phlegmariurus

The majority of the species formerly placed in a broadly defined Huperzia belong in Phlegmariurus. [4] However, the genera are difficult to separate morphologically, and others have preferred the one-genus division of the subfamily. [1]

Species

As of January 2023, the Checklist of Ferns and Lycophytes of the World accepted over 300 species: [1]

One hybrid is known: [1]

<i>Huperzia</i> Genus of vascular plants

Huperzia is a genus of lycophyte plants, sometimes known as the firmosses or fir clubmosses; the Flora of North America calls them gemma fir-mosses. This genus was originally included in the related genus Lycopodium, from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones. The common name firmoss, used for some of the north temperate species, refers to their superficial resemblance to branches of fir (Abies), a conifer. As of 2020, two very different circumscriptions of the genus were in use. In the Pteridophyte Phylogeny Group classification of 2016, Huperzia is one of three genera in the subfamily Huperzioideae of the family Lycopodiaceae. Most species in the subfamily are placed in the genus Phlegmariurus. Huperzia is left with about 25 species, although not all have been formally transferred to other genera. Other sources recognize only Huperzia, which then has about 340 species.

<i>Pteris</i> Genus of ferns in the subfamily Pteridoideae

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.

<i>Cheilanthes</i> Genus of ferns in the family Pteridaceae

Cheilanthes, commonly known as lip ferns, is a genus of about 180 species of rock-dwelling ferns with a cosmopolitan distribution in warm, dry, rocky regions, often growing in small crevices high up on cliffs. Most are small, sturdy and evergreen. The leaves, often densely covered in trichomes, spring directly from the rootstocks. Many of them are desert ferns, curling up during dry times and reviving with the coming of moisture. At the ends of veins sporangia, or spore-bearing structures, are protected by leaf margins, which curl over them.

<i>Cyathea</i> Genus of ferns

Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.

<i>Alsophila</i> (plant) Genus of ferns

Alsophila is a genus of tree ferns in the family Cyatheaceae. It has also been considered to be a section in the subgenus Cyathea of the genus Cyathea.

<i>Dennstaedtia</i> Genus of ferns

Dennstaedtia is a mostly tropical and subtropical genus of ferns described as a genus in 1801. Hayscented fern, or Cup ferns, are common names for some species in this genus. Its best-known member is probably the temperate North-American hay-scented fern, Dennstaedtia punctilobula, which forms extensive clonal ground-cover colonies on level surfaces in the Appalachian area.

<i>Hymenophyllum</i> Genus of plants

Hymenophyllum is a genus of ferns in the family Hymenophyllaceae. Its name means "membranous leaf", referring to the very thin translucent tissue of the fronds, which gives rise to the common name filmy fern for this and other thin-leaved ferns. The leaves are generally only one cell thick and lack stomata, making them vulnerable to desiccation. Consequently, they are found only in very humid areas, such as in moist forests and among sheltered rocks. They are small and easy to overlook.

<i>Tectaria</i> Genus of ferns

Tectaria is a genus of fern in the family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016. Halberd fern is a common name for species in this genus.

<i>Trichomanes</i> Genus of ferns

Trichomanes is a genus of ferns in the family Hymenophyllaceae, termed bristle ferns. The circumscription of the genus is disputed. All ferns in the genus are filmy ferns, with leaf tissue typically 2 cells thick. This thinness generally necessitates a permanently humid habitat, and makes the fronds somewhat translucent. Because of this membrane-like frond tissue, the plant is prone to drying out. “Filmy ferns” in the taxa Hymenophyllaceae grow in constantly wet environments. Many are found in cloud forests such as “Choco” in Colombia. There are also members of the taxa that can grow submersed in water.

<i>Selliguea</i> Genus of ferns

Selliguea is a fern genus in the family Polypodiaceae. The type species is Selliguea feei.

<i>Christella</i> Genus of ferns

Christella is a genus of around 70-80 species of ferns in the subfamily Thelypteridoideae of the family Thelypteridaceae in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Christella into a very broadly defined genus Thelypteris. The genus was named after Konrad H. Christ, a Swiss botanist. The distribution of these plants is mostly in the tropics and sub tropical areas. An Australian example is C. dentata.

<i>Abrodictyum</i> Genus of ferns

Abrodictyum is a fern genus in the family Hymenophyllaceae. The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016 but not by some other sources, which sink it into a broadly defined Trichomanes.

<i>Palhinhaea</i> Genus of plants

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.

<i>Amauropelta</i> Genus of ferns

Amauropelta is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink the genus into a very broadly defined genus Thelypteris.

<i>Coryphopteris</i> Genus of ferns

Coryphopteris is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016.

<i>Goniopteris</i> Genus of ferns

Goniopteris is a genus of ferns in the family Thelypteridaceae, subfamily Thelypteridoideae, in the Pteridophyte Phylogeny Group classification of 2016. Other sources sink Goniopteris into a very broadly defined genus Thelypteris.

<i>Grypothrix</i>

Grypothrix is a small genus of ferns in the family Thelypteridaceae.
