Kornmanniaceae is a family of green algae in the order Ulvales. [1]
Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Callitris is a genus of coniferous trees in the Cupressaceae. There are 16 recognized species in the genus, of which 13 are native to Australia and the other three native to New Caledonia. Traditionally, the most widely used common name is cypress-pine, a name shared by some species of the closely related genus Actinostrobus.
In 1984, the International Organization for Succulent Plant Study set up a working party, now called the International Cactaceae Systematics Group, to produce a consensus classification of the cactus family, down to the level of genus. Their classification has been used as the basis for systems published since the mid-1990s. Treatments in the 21st century have generally divided the family into around 125–130 genera and 1,400–1,500 species, which are then arranged in a number of tribes and subfamilies. However, subsequent molecular phylogenetic studies have shown that a very high proportion of the higher taxa are not monophyletic, i.e. they do not contain all of the descendants of a common ancestor. As of March 2017, the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was produced by Nyffeler and Eggli in 2010.
In biological nomenclature, a nomen novum, new replacement name is a technical term. It indicates 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..
Codiaceae is a family of green algae in the order Bryopsidales.
Dictyochloropsis is a genus of unicellular green alga of the phylum Chlorophyta. This genus consists of free-living algae which have a reticulate (net-like) chloroplast that varies slightly in morphology between species, and that when mature always lacks a pyrenoid. Dictyochloropsis is asexual and reproduces using autospores.
Kornmannia is a genus of green algae in the family Kornmanniaceae.
Physolinum is a genus of green algae in the family Trentepohliaceae. The only species in the genus, Physolinum monilia, is currently regarded as a synonym of Trentepohlia rigidula.
Valonia is a genus of green algae in the Valoniaceae family. The cells have multiple nuclei and many chloroplasts, each with a pyrenoid. The cells of some species are very large, up to 2 cm in diameter. In some species the colonies maintain a symmetrical shape but in others they do not. Some species have been extensively used for studies of ion-exchange and water potential across biological membranes.
Dilabifilum is a genus of thalloid green algae comprising approximately 4 species. The thalli take a crustose form. Choreonema reproduces by means of conceptacles; it produces tetraspores and dispores and carpospores. It is a source of agar.
Halothamnus subaphyllus is a species of the plant genus Halothamnus, that belongs to the subfamily Salsoloideae within the family Amaranthaceae,. It occurs in Southwest and Central Asia.
Halothamnus glaucus is a species of the plant genus Halothamnus, that belongs to the subfamily Salsoloideae of the family Amaranthaceae,. It occurs in Western and Central Asia.
Nomen illegitimum is a technical term, used mainly in botany. It is usually abbreviated as nom. illeg. Although the International Code of Nomenclature for algae, fungi, and plants uses Latin terms for other kinds of name, the glossary defines the English phrase "illegitimate name" rather than the Latin equivalent. However, the Latin abbreviation is widely used by botanists and mycologists.
Zephyranthes atamasca, commonly known as the atamasco-lily or more generally a rain-lily, is native to the southeastern United States. It grows in swampy forests and coastal prairies, preferring acid boggy soils rich with leaf mold. Following the appearance of broad, grassy leaves in early winter, it blooms in March or April. It has several narrow, linear basal leaves about 0.5 in (13 mm) wide and 10–15 in (25–38 cm) long. Its native range extends from Florida north to Maryland and west to Mississippi. The species is also naturalized in Bermuda and in the Mariana Islands. Both its leaves and bulbs are poisonous.

Hapalidiaceae is a family of red alga belonging to the order Corallinales.
The Mesotaeniaceae are a small family of unicellular green algae known as the "saccoderm desmids". The Mesotaeniaceae appear to be sister or ancestral to the Zygnemataceae. The desmids are a deep branching group of Zygnemataceae. Spirotaenia was found to be a basal green alga.
Neoceratium tripos is a species of dinoflagellates of the genus Neoceratium.
Elisabeth Tschermak-Woess was an Austrian University lecturer, cytologist, and phycologist who worked with lichen photobionts. In 1994, Tschermak-Woess was awarded the Acharius Medal for her lifetime contributions to lichenology. She had a Festschrift dedicated to her in 1988, in the journal Plant Systematics and Evolution. Lichen taxa that have been named after Tschermak-Woess include the genus Woessia and the species Asterochloris woessiae.
