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.
Begonia is a genus of perennial flowering plants in the family Begoniaceae. The genus contains more than 1,800 different plant species. The Begonias are native to moist subtropical and tropical climates. Some species are commonly grown indoors as ornamental houseplants in cooler climates. In cooler climates some species are cultivated outside in summertime for their bright colorful flowers, which have sepals but no petals.
Mangifera is a genus of flowering plants in the cashew family, Anacardiaceae. It contains approximately 69 species, with the best-known being the Common Mango. The center of diversity is in subtropical and tropical South Asia and Southeast Asia, while the highest number of species occur in India. They are generally canopy trees in lowland rainforests, reaching a height of 30–40 m (98–131 ft).
Achillea is a group of flowering plants in the family Asteraceae, known colloquially as yarrows. They were described as a genus by Linnaeus in 1753. The genus was named after the Greek mythological character Achilles. According to legend, Achilles' soldiers used yarrow to treat their wounds, hence some of its common names such as allheal and bloodwort.
Goldenrod is a common name for many species of flowering plants in the sunflower family, Asteraceae, commonly in reference to the genus Solidago.
Agapanthus is the only genus in the subfamily Agapanthoideae of the flowering plant family Amaryllidaceae. The family is in the monocot order Asparagales. The name is derived from Greek: ἀγάπη, ἄνθος.
Hepatica is a genus of herbaceous perennials in the buttercup family, native to central and northern Europe, Asia and eastern North America. Some botanists include Hepatica within a wider interpretation of Anemone.
Conium is one of more than 400 genera of flowering plants in the carrot family Apiaceae. As of December 2020, Plants of the World Online accepts six species.
Gesneriaceae, the gesneriad family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World and the New World, with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants.
Bombax is a genus of mainly tropical trees in the mallow family. They are native to western Africa, the Indian subcontinent, Southeast Asia, and the subtropical regions of East Asia and northern Australia. It is distinguished from the genus Ceiba, which has whiter flowers.
Epiphyllum is a genus of epiphytic plants in the cactus family (Cactaceae), native to Central America. Common names for these species include climbing cacti, orchid cacti and leaf cacti, though the latter also refers to the genus Pereskia.
Symphyotrichum is a genus of over 90 species of herbaceous annual and perennial plants in the composite family (Asteraceae) that were formerly treated within the genus Aster. The majority are endemic to North America, but several species also occur in the West Indies, Central and South America, as well as in eastern Eurasia. Many species have been introduced to Europe as garden specimens, most notably New England aster and New York aster.
Isopogon anethifolius, commonly known as narrow-leaf drumsticks or narrow-leafed drumsticks, is a shrub in the family Proteaceae. The species is found only in coastal areas near Sydney in New South Wales, and to the immediate west. It occurs naturally in woodland, open forest and heathland on sandstone soils. An upright shrub, it can reach to 3 m (10 ft) in height, with terete leaves that are divided and narrow. The yellow flowers appear in the Spring, from September to December, and are prominently displayed. They are followed by round grey cones, which give the plant its common name of drumsticks. The small hairy seeds are found in the old flower parts.
Goodenia is a genus of about two hundred species of flowering plants in the family Goodeniaceae. Plants in this genus are herbs or shrubs, mostly endemic to Australia. The leaves are variably-shaped, the flowers arranged in small groups, with three or five sepals, the corolla bilaterally symmetrical and either fan-shaped with two "lips" or tube-shaped. The petals are usually yellow to white, the stamens free from each other and the fruit a capsule.
Disphyma is a genus of flowering plants in the family Aizoaceae that are native to New Zealand, Australia and southern Africa. Plants in this genus are prostrate, annual or short-lived perennial shrubs with succulent leaves and daisy-like flowers arranged singly on the ends of shoots with petal-like staminodes, many stamens and usually five styles.
The Interim Register of Marine and Nonmarine Genera (IRMNG) is a taxonomic database which attempts to cover published genus names for all domains of life from 1753 in zoology up to the present, arranged in a single, internally consistent taxonomic hierarchy, for the benefit of Biodiversity Informatics initiatives plus general users of biodiversity (taxonomic) information. In addition to containing over 490,000 published genus name instances as at March 2020, the database holds over 1.7 million species names, although this component of the data is not maintained in as current or complete state as the genus-level holdings. IRMNG can be queried online for access to the latest version of the dataset and is also made available as periodic snapshots or data dumps for import/upload into other systems as desired.
Oreobolus is a genus of flowering plants in the family Cyperaceae. The genus has a circumpacific distribution.
Protea revoluta, also known as the roll-leaved sugarbush or rolled-leaf sugarbush, is a species of plant which is classified in the genus Protea. P. revoluta is only found growing in the wild in South Africa, where plants can be found growing between the Cederberg inland on the Atlantic coast and the Witteberg area to the north.
Casselia is a small genus of flowering plants in the verbena family (Verbenaceae) first named in 1823. Plants in the genus Casselia are native to South America.
