Gentianaceae is a family of flowering plants of 103 genera and about 1600 species.
Centaurium (centaury) is a genus of 20 species in the gentian family (Gentianaceae), tribe Chironieae, subtribe Chironiinae. The genus was named after the centaur Chiron, famed in Greek mythology for his skill in medicinal herbs. It is distributed across Europe and into Asia.
The genus Macrocarpaea, with 105 species and two hybrids of 0.5 m herbs, shrubs, epiphytes and small trees to 10 m tall, is the largest genus of the tribe Helieae of the gentian family (Gentianaceae). Species of Macrocarpaea have diurnal and nocturnal pollinators, visited during the day by hummingbirds, insects and butterflies, and at night by bats, moths and many different kinds of insects. The common name for the genus is 'Moon-gentian'. No species are known in cultivation.
Centaury is a common name for several plants and may refer to:
Zeltnera beyrichii, commonly known as mountain pink, quinine weed or rock centaury, is an annual plant in the New World that blooms from late spring to early fall. Used as a medicinal plant by pioneers, the flowers were dried and used to reduce fevers.
Schenkia sebaeoides, known as ʻĀwiwi in Hawaiian and lavaslope centaury in English, is a rare species of flowering plant. It is endemic to low shrublands in the state of Hawaiʻi in the United States. It is present on the islands of Kauai, Oahu, Lanai, Molokai, and Maui. At the time it was added to the endangered species list of the United States in 1991 it was known from seven populations for a total of fewer than 1000 individuals. It is threatened by habitat loss.
Zeltnera venusta is a species of flowering plant in the gentian family known by the common names California centaury, charming centaury and canchalagua. This centaury is native to much of California, southern Oregon, and northwest Baja California.
Zeltnera muehlenbergii is a species of annual herb commonly known as Monterey centaury and Muhlenberg's centaury. It is native to western North America from British Columbia to California and Nevada, where it commonly grows in forests and other moist places. This is an annual herb growing thin, erect, branching stems to heights anywhere between 10 centimeters and one meter. Oval-shaped leaves are arranged oppositely on the stem and are up to 2 or 3 centimeters long. The branching inflorescence bears many flowers, each with small bracts at its base. The flower has five oval-shaped petallike lobes each a few millimeters long.
Schenkia australis is a species of annual herb in the Gentianaceae family. It is endemic to Australia.
Schenkia is a genus of flowering plants in the gentian family, Gentianaceae. It is sometimes included in the genus Centaurium.
Sebaea is a genus of annual plants in the family Gentianaceae. Species occur in Africa, Madagascar, India, China, Thailand, Australia and New Zealand. The genus was paraphyletic and has been split in four genera: Exochaenium, Klackenbergia, Lagenias and Sebaeas.str.. Synapomorphies for Sebaea s.str. include the presence of extra stigma along the style and the shape of the testa cells of the seeds.
Zeltnera is a genus of flowering plants in the gentian family. It was erected in 2004 when the genus Centaurium was split. Genetic analysis revealed that Centaurium was polyphyletic, made up of plants that could be grouped into four clades. Each became a genus. Centaurium remained, but it is now limited to the Eurasian species. The Mexican species now belong to genus Gyrandra, and the Mediterranean and Australian plants are in genus Schenkia. The new name Zeltnera was given to this genus, which contains most of the North American centauries. There are about 25 species.
The genus Exochaenium is endemic to sub-Saharan Africa, with species occurring in most tropical and sub-tropical regions of the continent, particularly on the Katanga plateau, with many extending to the Sudano-Zambesian and Guineo-Congolian regions. The genus is monophyletic and is used to study the variation and evolution of herkogamy.
Exaceae is a flowering plant tribe in the family Gentianaceae. Exaceae comprises about 180 species assigned to eight monophyletic genera, with major centres of endemism in continental Africa, Madagascar and the southern tip of India and Sri Lanka (14 endemic species).
Tachiadenus is a plant genus in the gentian family (Gentianaceae), tribe Exaceae. It contains 12 species. The genus is endemic to Madagascar.
Centaurium scilloides, also known as perennial centaury is a flowering plant in the family Gentianaceae. It is native to Atlantic Europe and the Azores. Plants from the Azores have white flowers and are genetically different with some treating it as a different species.
Gyrandra is a genus of flowering plants in the family Gentianaceae, found in Texas, Mexico and Central America. Annual herbs, they are usually found in montane pine-oak forests.
Utania is a genus of flowering plants belonging to the gentian family (Gentianaceae), the tribe Potalieae, and the subtribe Potaliinae. A small genus it has 12 species.
Centaurium littorale, the seaside centaury, is a species of flowering plant belonging to the family Gentianaceae.
Zonanthus is a genus of flowering plants belonging to the family Gentianaceae.
