Oleaceae, also known as the olive family or sometimes the lilac family, is a taxonomic family of flowering shrubs, trees, and a few lianas in the order Lamiales. It presently comprises 28 genera, one of which is recently extinct. The extant genera include Cartrema, which was resurrected in 2012. The number of species in the Oleaceae is variously estimated in a wide range around 700. The flowers are often numerous and highly odoriferous. The family has a subcosmopolitan distribution, ranging from the subarctic to the southernmost parts of Africa, Australia, and South America. Notable members include olive, ash, jasmine, and several popular ornamental plants including privet, forsythia, fringetrees, and lilac.
Bignoniaceae is a family of flowering plants in the order Lamiales commonly known as the bignonias or trumpet vines. It is not known to which of the other families in the order it is most closely related.
Jacaranda is a genus of 49 species of flowering plants in the family Bignoniaceae, native to tropical and subtropical regions of the Americas while cultivated around the world. The generic name is also used as the common name.
Paulowniaceae are a family of flowering plants within the Lamiales. They are a monophyletic and monogeneric family of trees with currently 7 confirmed species. They were formerly placed within Scrophulariaceae sensu lato, or as a segregate of the Bignoniaceae.
The Monimiaceae is a family of flowering plants in the magnoliid order Laurales. It is closely related to the families Hernandiaceae and Lauraceae. It consists of shrubs, small trees, and a few lianas of the tropics and subtropics, mostly in the southern hemisphere. The largest center of diversity is New Guinea, with about 75 species. Lesser centres of diversity are Madagascar, Australia, and the neotropics. Africa has one species, Xymalos monospora, as does Southern Chile. Several species are distributed through Malesia and the southwest Pacific.
Phrymaceae, also known as the lopseed family, is a small family of flowering plants in the order Lamiales. It has a nearly cosmopolitan distribution, but is concentrated in two centers of diversity, one in Australia, the other in western North America. Members of this family occur in diverse habitats, including deserts, river banks and mountains.
Boraginales is an order of flowering plants in the asterid clade, with a total of about 125 genera and 2,700 species. Different taxonomic treatments either include only a single family, the Boraginaceae, or divide it into up to eleven families. Its herbs, shrubs, trees and lianas (vines) have a worldwide distribution.
Raukaua is a genus of flowering plants in the family Araliaceae. It has an austral distribution, being indigenous to southern Argentina and Chile, as well as New Zealand and the island of Tasmania.
Handroanthus impetiginosus, the pink ipê, pink lapacho or pink trumpet tree, is a tree in the family Bignoniaceae, distributed throughout North, Central and South America, from northern Mexico south to northern Argentina. Along with all the other species in the Handroanthus genus, it is the national tree of Paraguay.
Lapachol is a natural phenolic compound isolated from the bark of the lapacho tree. This tree is known botanically as Handroanthus impetiginosus, but was formerly known by various other botanical names such as Tabebuia avellanedae. Lapachol is also found in other species of Handroanthus.
Handroanthus chrysotrichus, synonym Tabebuia chrysotricha, commonly known as the golden trumpet tree, is a semi-evergreen/semi-deciduous tree from Brazil. It is very similar to and often confused with Tabebuia ochracea. In Portuguese it is called ipê amarelo and its flower is considered the national flower of Brazil.
When the APG II system of plant classification was published in April 2003, fifteen genera and three families were placed incertae sedis in the angiosperms, and were listed in a section of the appendix entitled "Taxa of uncertain position".
Alwyn Howard Gentry was an American botanist and plant collector, who made major contributions to the understanding of the vegetation of tropical forests.
Handroanthus is a genus of flowering plants in the family Bignoniaceae. It consists of 30 species of trees, known in Latin America by the common names poui, pau d'arco, or ipê. The latter sometimes appears as epay or simply ipe (unaccented) in English. The large timber species are sometimes called lapacho or guayacan, but these names are more properly applied to the species Handroanthus lapacho and Handroanthus guayacan, respectively.
Roseodendron is a genus of flowering plants in the family Bignoniaceae. It consists of two species, Roseodendron donnell-smithii and Roseodendron chryseum. The type species for the genus is R. donnell-smithii. Both species are cultivated as ornamentals for their numerous, large, yellow flowers.
Ekmanianthe is a genus of flowering plants in the family Bignoniaceae. It is most closely related to Tabebuia and has sometimes been included within it. It consists of two species of trees, neither of which is especially common in any part of its range:
Astianthus is a monotypic genus of flowering plants in the Bignoniaceae family. The sole species is Astianthus viminalis. It is known by the common names achuchil in Mexico and chilca in Guatemala and Honduras.
Handroanthus heptaphyllus, commonly referred to as the pink trumpet tree or pink tab, is a Bignoniaceae tree native to tropical and subtropical regions of South America. It grows in the high forest watershed of the Paraná River, Paraguay River and Uruguay River. It has a limited distribution, almost exclusively inhabiting low lands with wet and deep soils, where it forms part of the upper layer of tree cover.
Exarata is a group of plants described as a genus in 1992.
Heterophragma is a genus of two species of tree, constituting part of the plant family Bignoniaceae. The species are found in Southeast Asia and India.
