Selaginellaceae
''Selaginella'' is the sole genus of vascular plants in the family Selaginellaceae, the spikemosses or lesser clubmosses. This family is distinguished from Lycopodiaceae The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) 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 mil ... (the clubmosses) by having scale-leaves bearing a ligule and by having heterospory, spores of two types. They are sometimes included in an informal paraphyletic group called the "fern ally, fern allies". ''Selaginella moellendorffii, S. moellendorffii'' is an important model organism. Its genome has been sequenced by the United States Department of Energy's Joint Genome Institute. The name ''Selaginella'' was erected by Palisot de Beauvois solely for the species ''Selaginella selaginoides'', which turns out (with the closely related ''Selaginella deflexa'') to ...

Selaginella Deflexa
''Selaginella'' is the sole genus of vascular plants in the family Selaginellaceae, the spikemosses or lesser clubmosses.

Selaginella Kraussiana
''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 belongs to the very ancient lineage of plants known as the clubmosses. Description Growing to just high, it is a low-growing, mat-forming evergreen perennial with primitive fern-like leaves, that spreads via rooting stems. Seginella kraussiana.jpg, Illustrating greener coloration when grown in brighter light Selaginella kraussiana OB10.1.jpg, Close-up of the foliage Distribution Its native distribution is the Macaronesia, and parts of south and east Africa. Its native distribution in the Azores was controversial up until 2005, when spores of this species were discovered in 6,000-year-old fossils on Pico. Since its introduction to Britain in 1878 it has spread slowly, and was first recorded in the wild in 1917 in west ...

Ambroise Marie François Joseph Palisot De Beauvois
Ambroise Marie François Joseph Palisot, Baron de Beauvois (27 July 1752, in Arras – 21 January 1820, in Paris) was a French naturalist and zoologist. Palisot collected insects in Oware, Benin, Saint Domingue, and the United States, from 1786 to 1797. Trained as a botanist, Palisot published a significant entomological paper entitled, "Insectes Receuillis en Afrique et en Amerique". Together with Frederick Valentine Melsheimer, he was one of the first entomologists to collect and describe American insects. He described many common insects and suggested an ordinal classification of insects. He described many Scarabaeidae as well as illustrating them for the first time. The study included 39 '' Scarabaeus'' species, 17 ''Copris'' species, 7 ''Trox'' species, 4 ''Cetonia'' and 4 '' Trichius'' species. Familiar beetles such as '' Canthon viridis'', '' Macrodactylus angustatus'' and '' Osmoderma scabra'' were first described by him. Many of the specimens that were labelled from Am ...

Lycopodiopsida
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 formed huge forests that dominated the landscape and contributed to coal deposits. The nomenclature and classification of plants with microphylls varies substantially among authors. A consensus classification for extant (living) species was produced in 2016 by the Pteridophyte Phylogeny Group (PPG I), which places them all in the class Lycopodiopsida, which includes the classes Isoetopsida and Selaginellopsida used in other systems. (See Table 2.) Alternative classification systems have used ranks fro ...

Ligule
A ligule (from "strap", variant of ''lingula'', from ''lingua'' "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae. Poaceae and Cyperaceae The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs. The membranous ligule can be very short 1–2 mm (Kentucky bluegrass, ''Poa pratensis'') to very long 10–20 mm (Johnson grass, ''Sorghum halepense''), it can also be smooth on the edge or very ragged. Some grasses do not have a ligule, for example barnyardgrass (''Echinochloa crus-galli''). A ligule can also be defined as a membrane-like tissue or row of delicate hairs typically found in grasses at the junction of the leaf sheath and blade. The ...

Selaginella Erythropus
''Selaginella erythropus'' is a species of plant in the Selaginellaceae family, endemic to the Yucatan and Belize to Colombia and was introduced to Tanzania Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and .... It grows up to 30–40 cm in height with a bright red main stem. It likes plentiful water and humidity and enjoys temperatures of 50-75 degrees Fahrenheit (10-24 degrees Celsius). The top of the plant is green and the undersides of the leaves are a bright, ruby red color. It is a species of spike moss (also known as clubmoss) which is related to the fern family. Spike mosses reproduce through spores just like ferns do. Synonyms * ''Lycopodium erythropus'' Mart. References * ''Fl. Bras.'' 1(2): 125 1840.

Antoine Frédéric Spring
Antoine Frédéric Spring (8 April 1814 in Gerolsbach, Bavaria – 17 January 1872) was a German-born, Belgian physician and botanist. He studied botany and medicine at the University of Munich, obtaining his PhD in 1835 and his medical doctorate during the following year. From 1839 to 1872 he was a professor at the University of Liège, initially in the fields of physiology and anatomy, later teaching classes in pathology and internal medicine. As a botanist he specialized in research of Lycopodiaceae (clubmosses) and Selaginellaceae (spikemosses), and was the binomial author of numerous species from both families.IPNI

Lycopodiaceae
The Lycopodiaceae (class Lycopodiopsida, order Lycopodiales) 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. Description Members of Lycopodiaceae are not spermatophytes and so do not produce seeds. Instead they produce spores, which are oily and flammable, and are the most economically important aspects of these plants. The spores are of one size (i.e. the plants are isosporous) and are borne on a specialized structure at the apex of a shoot called a strobilus (plural: strobili), which resembles a tiny battle club, from which the common name derives. Members of the family share the common feature of having a microphyll, ...
