Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. 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.
Eragrostis is a large and widespread genus of plants in the grass family, found in many countries on all inhabited continents and many islands.
Oryza is a genus of plants in the grass family. It includes the major food crop rice. Members of the genus grow as tall, wetland grasses, growing to 1–2 metres (3–7 ft) tall; the genus includes both annual and perennial species.
Botrychium is a genus of ferns, seedless vascular plants in the family Ophioglossaceae. Botrychium species are known as moonworts. They are small, with fleshy roots, and reproduce by spores shed into the air. One part of the leaf, the trophophore, is sterile and fernlike; the other, the sporophore, is fertile and carries the clusters of sporangia or spore cases. Some species only occasionally emerge above ground and gain most of their nourishment from an association with mycorrhizal fungi.
Hoodia is a genus of flowering plants in the family Apocynaceae, under the subfamily Asclepiadoideae, native to Southern Africa.
Koelreuteria, also known as chinese lantern tree, is a genus of three species of flowering plants in the family Sapindaceae, native to southern and eastern Asia.
Falconeria is a monotypic plant genus in the family Euphorbiaceae, first described as a genus in 1839. The genus is sometimes included within the genus Sapium. The sole species is Falconeria insignis. The plant is found from India, Nepal, Bangladesh, and Sri Lanka to Indochina, China, Thailand and Peninsular Malaysia.
Polystichum is a genus of ferns in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016. The genus has about 500 species and has a cosmopolitan distribution. The highest diversity is in eastern Asia, with about 208 species in China alone; the region from Mexico to Brazil has at least 100 additional species; Africa, North America, and Europe have much lower diversity. Polystichum species are terrestrial or rock-dwelling ferns of warm-temperate and montane-tropical regions. They are often found in disturbed habitats such as road cuts, talus slopes, and stream banks.
Cardamine hirsuta, commonly called hairy bittercress, is an annual or biennial species of plant in the family Brassicaceae, and is edible as a salad green. It is common in moist areas around the world.
Sium suave, the water parsnip or hemlock waterparsnip, is a perennial wildflower in the family Apiaceae. It is native to many areas of both Asia and North America. The common name water parsnip is due to its similarity to parsnip and its wetland habitat. The alternate common name hemlock waterparsnip is due to its similarity to the highly poisonous spotted water hemlock.
Boschniakia is a genus of parasitic plants in the family Orobanchaceae. They are known commonly as groundcones and they are native to western North America and extreme northeastern Asia. Some taxonomists consider Boschniakia to be three separate genera: Boschniakia, Kopsiopsis, and Xylanche. When the genus is split, only a single species remains: Boschniakia rossica, the northern groundcone.
Syringodium is a genus in the family Cymodoceaceae described as a genus in 1860. It is found along shorelines of tropical and subtropical marine environments.
Halodule is a genus of plants in the family Cymodoceaceae described as a genus in 1841. It is widespread on tropical and semi-tropical ocean shores of all continents except Europe and Antarctica.
Cymodocea is a genus in the family Cymodoceaceae described as a genus in 1805. It includes four species of sea grass distributed in warm oceans.
Gossweilera is a genus of African flowering plants in the family Asteraceae.
Clappia suaedifolia is the sole species in the North American genus of flowering plants in the family Asteraceae, Clappia.
Irvingia is a genus of African and Southeast Asian trees in the family Irvingiaceae, sometimes known by the common names wild mango, African mango, bush mango, dika, mbukpap uyo or ogbono. They bear edible mango-like fruits, and are especially valued for their fat- and protein-rich nuts.
Maundia is a genus of alismatid monocots, described in 1858. Maundia was formerly included in the family Juncaginaceae but is now considered to form a family of its own under the name Maundiaceae. It contains only one known species, Maundia triglochinoides, endemic to Australia.
Johrenia is a genus of herbaceous plants of the family Apiaceae.
× Aegilotriticum is a nothogenus of flowering plants in the family Poaceae. They are the result of crosses between species of two distinct grass genera, Aegilops (goatgrasses) and Triticum (wheat). This type of intergeneric hybridization is quite rare, and is indicated by a multiplication symbol before the name. The name Aegilotriticum is an example of a portmanteau word, a combination of the two parents' names. This genus has at least 7 species.
