Pseudolycopodium is a genus of lycophyte in the family Lycopodiaceae with only one species, Pseudolycopodium densum, known as the bushy clubmoss. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the genus is placed in the subfamily Lycopodioideae. [4] Some sources do not recognize the genus, sinking it into Lycopodium . [5] Pseudolycopodium densum is native to Australia, the North Island of New Zealand and New Caledonia. [1] [2] It is a spore-bearing vascular plant and grows up to a metre high. It is found in a wide variety of situations, often in high rainfall areas on sandy soils. [6] [7]

Taxonomy

The species was first described in 1807 by Jacques Labillardière, as Lycopodium densum. However, the name had already been used for a different species, so this name is illegitimate. [3] Hence when Werner Rothmaler in 1944 placed the species in the genus Lepidotis as Lepidotis densa, this was the first legitimate use of the epithet. [8] In 1983, Josef Holub placed the species in his genus Pseudolycopodium. This placement is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), [4] and by the Checklist of Ferns and Lycophytes of the Worldas of June 2024. [1] Other sources retain the species in its original genus, Lycopodium, where the legitimate name is Lycopodium deuterodensumHerter. [2] [6] [7] [9] [10] [11] [12] [13] [14]

Distribution and habitat

Pseudolycopodium (as Lycopodium deuterodensum) grows in open forest, scrub or heath in eastern New South Wales, southern Victoria, Tasmania (including Bass Strait Islands, Queensland, South Australia the North and Chatham Islands of New Zealand and in New Caledonia.

<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.

<span class="mw-page-title-main">Lycopodiaceae</span> Family of vascular plants

The Lycopodiaceae are an old family of vascular plants, including all of the core clubmosses and firmosses, comprising 16 accepted genera and about 400 known species. This family originated about 380 million years ago in the early Devonian, though the diversity within the family has been much more recent. "Wolf foot" is another common name for this family due to the resemblance of either the roots or branch tips to a wolf's paw.

<i>Lycopodium</i> Genus of vascular plants in the family Lycopodiaceae

Lycopodium is a genus of clubmosses, also known as ground pines or creeping cedars, in the family Lycopodiaceae. Two very different circumscriptions of the genus are in use. In the Pteridophyte Phylogeny Group classification of 2016, Lycopodium is one of nine genera in the subfamily Lycopodioideae, and has from nine to 15 species. In other classifications, the genus is equivalent to the whole of the subfamily, since it includes all of the other genera. More than 40 species are accepted.

<i>Diphasiastrum</i> Genus of vascular plants in the clubmoss family Lycopodiaceae

Diphasiastrum is a genus of clubmosses in the plant family Lycopodiaceae. In the Pteridophyte Phylogeny Group classification of 2016, it is placed in the subfamily Lycopodioideae. It is closely related to the genus Lycopodium, and some botanists treat it within a broad view of that genus as a section, Lycopodium sect. Complanata. Some species superficially resemble diminutive gymnosperms and have been given common names such as ground-pine or ground-cedar.

<i>Lycopodiella</i> Genus of spore-bearing plants

Lycopodiella is a genus in the clubmoss family Lycopodiaceae. The genus members are commonly called bog clubmosses, describing their wetland habitat. The genus has a cosmopolitan distribution, with centers of diversity in the tropical New World and New Guinea. In the past, the genus was often incorporated within the related genus Lycopodium, but was segregated in 1964. In the Pteridophyte Phylogeny Group classification of 2016, Lycopodiella is placed in the subfamily Lycopodielloideae, along with three other genera. In this circumscription, the genus has about 15 species. Other sources use a wider circumscription, in which the genus is equivalent to the Lycopodielloideae of PPG I, in which case about 40 species and hybrids are accepted.

In biological nomenclature, a nomen novum, new replacement name is a scientific name that is created specifically to replace another scientific name, but only when this other name cannot be used for technical, nomenclatural reasons. It does not apply when a name is changed for taxonomic reasons. It is frequently abbreviated, e.g.nomen nov., nom. nov..
