Lycopodiopsida is a class of vascular plants known as lycopods, lycophytes or other terms including the component lyco-. Members of the class are also called clubmosses, firmosses, spikemosses and quillworts. They have dichotomously branching stems bearing simple leaves called microphylls and reproduce by means of spores borne in sporangia on the sides of the stems at the bases of the leaves. Although living species are small, during the Carboniferous, extinct tree-like forms (Lepidodendrales) formed huge forests that dominated the landscape and contributed to coal deposits.
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.
Equisetidae is one of the four subclasses of Polypodiopsida (ferns), a group of vascular plants with a fossil record going back to the Devonian. They are commonly known as horsetails. They typically grow in wet areas, with whorls of needle-like branches radiating at regular intervals from a single vertical stem.
Lycopodium clavatum is the most widespread species in the genus Lycopodium in the clubmoss family.
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.
Selaginella lepidophylla, also known as a resurrection plant, is a species of desert plant in the spikemoss family (Selaginellaceae). It is native to the Chihuahuan Desert of the United States and Mexico. S. lepidophylla is renowned for its ability to survive almost complete desiccation. Resurrection plants are vascular rooted plants capable of surviving extreme desiccation, then resuming normal metabolic activity upon rehydration. The plant's hydro-responsive movements are governed by stem moisture content, tissue properties and a graded distribution of lignified cells affecting concentric stem stiffness and spiraling. During dry weather in its native habitat, its stems curl into a tight ball, uncurling only when exposed to moisture.
Phlegmariurus phlegmaria, synonym Huperzia phlegmaria, commonly known as either coarse tassel fern or common tassel fern, is an epiphytic species native to rainforests in Madagascar, some islands in the Indian Ocean, Asia, Australasia and many Pacific Islands. Phlegmariurus phlegmaria is commonly found in moist forests and rainforests at high altitudes, in and amongst mosses and other epiphytes. Members of the order Lycopodiales are commonly referred to as clubmosses.
Selaginella apoda, commonly known as meadow spikemoss, is a perennial lycophyte native to much of the eastern United States and parts of northeastern Mexico. The life cycle is the shortest of the genus Selaginella, as well as one of the shortest among the lycophytes. Selaginella apoda is found primarily in damp soils in habitats such as swamps, wet fields, open woods and along stream banks. Selaginella apoda presents the potential for case studies involving the plant's adaptability to environmental toxins. A lowland plant, it has only been recorded at elevations below 100 meters. It is closely related to Selaginella eclipes and S. ludoviciana, with both of which it has been reported to form hybrids. This group is characterized by relatively flat strobili and large megasporophylls which occur in the same plane as the lateral leaves.
Selaginella selaginoides is a non-flowering plant of the spikemoss genus Selaginella with a wide distribution around the Northern Hemisphere. It resembles a moss in appearance but is a vascular plant belonging to the division Lycopodiophyta. It has a number of common names including lesser clubmoss, club spikemoss, northern spikemoss, low spikemoss and prickly mountain-moss. This plant has one close relative, Selaginella deflexa, native to Hawaii. These two plants form a small clade that is sister to all other Selaginella species.

Selaginella kraussiana is a species of vascular plant in the family Selaginellaceae. It is referred to by the common names Krauss' spikemoss, Krauss's clubmoss, or African clubmoss, and is found naturally in parts of Sub-Saharan Africa and in Macaronesia. It is sometimes given the misnomer of “peacock fern”, due to its lacy leaf structure, despite having no relation to actual ferns; rather, it belongs to the very ancient lineage of plants known as the clubmosses.
Selaginella uliginosa is a small plant in the spikemoss family Selaginellaceae which is endemic to Australia. An ancient and primitive plant, usually under 10 centimetres tall, it is often seen in sunny moist areas. The specific epithet uliginosa is from Latin, referring to the plant's preference for growing in swampy locations.
Selaginella denticulata, or Mediterranean clubmoss, is a non-flowering plant of the spikemoss genus Selaginella with a wide distribution around the Northern Hemisphere.
Selaginella stellata, also recognized by its common name, starry spikemoss or starry spike-moss, is a species of spikemoss of the family Selaginellaceae. It is a type of lycopod that grows naturally in Mexico and Central American countries like Guatemala and Belize and can also be found in the state of Hawaii.
Alice Faber Tryon (1920–2009) was an American botanist who specialized in the systematics of ferns and other spore-dispersed plants (pteridology). She had two general areas of interest in her work, first incorporating the use of spore surface patterns into the understanding of fern diversity and systematics, and second the fern family Pteridaceae.
The Melaniellaceae are a family of fungi in the division Basidiomycota and order of Doassansiales. The family contains 1 genera and 2 species. They have a distribution in south and south-east Asia.
Selaginella deflexa, commonly known as deflexed spikemoss, is a non-flowering species of plant in the spikemoss genus Selaginella and is in the subgenus of the same name. It is closely related to Selaginella selaginoides which is the only other member in its subgenus. It is endemic to Hawaii and grows primarily in the wet tropical biome from 1,050–1,500 m (3,440–4,920 ft). can be found on all major islands except for Lana'i. It is usually found growing in wet moss. Unlike most members of Selaginella,S. deflexa does not have rhizophores along its stem. It gets its name from its reflexed leaves which point outwards.
