The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within 9 families. The order is placed in the eurosids II, which are part of the eudicots.
In biological classification, a subfamily is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae".
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks above genus are capitalized, including both tribe and subtribe.
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as Alcea (hollyhock), Malva (mallow) and Lavatera, as well as Tilia. The largest genera in terms of number of species include Hibiscus, Sterculia, Dombeya, Pavonia and Sida.
Bombacaceae were long recognised as a family of flowering plants or Angiospermae. The family name was based on the type genus Bombax. As is true for many botanical names, circumscription and status of the taxon has varied with taxonomic point of view, and currently the preference is to transfer most of the erstwhile family Bombacaceae to the subfamily Bombacoideae within the family Malvaceae in the order Malvales. The rest of the family were transferred to other taxa, notably the new family Durionaceae. Irrespective of current taxonomic status, many of the species originally included in the Bombacaceae are of considerable ecological, historical, horticultural, and economic importance, such as balsa, kapok, baobab and durian.
The Thymelaeaceae are a cosmopolitan family of flowering plants composed of 50 genera and 898 species. It was established in 1789 by Antoine Laurent de Jussieu. The Thymelaeaceae are mostly trees and shrubs, with a few vines and herbaceous plants.
Tiliaceae is a botanical name for a family of flowering plants. It is not a part of the APG, APG II and APG III classifications, being sunk in Malvaceae but has an extensive historical record of use.
Sterculiaceae was a family of flowering plants: based on the genus Sterculia. Genera are now placed in the family Malvaceae, in the subfamilies: Byttnerioideae, Dombeyoideae, Helicteroideae and Sterculioideae.
Tilioideae is a flowering plant subfamily in the family Malvaceae, though it was formerly considered a large group, placed at family rank and called Tiliaceae.
Malvoideae is a botanical name at the rank of subfamily, which includes in the minimum the genus Malva. It was first used by Burnett in 1835, but was not much used until recently, where, within the framework of the APG System, which unites the families Malvaceae, Bombacaceae, Sterculiaceae and Tiliaceae of the Cronquist system, the aggregate family Malvaceae is divided into 9 subfamilies, including Malvoideae. The Malvoideae of Kubitzki and Bayer includes 4 tribes:-
Bombacoideae is a subfamily of the mallow family, Malvaceae. It contains herbaceous and woody plants. Their leaves are alternate, commonly palmately lobed, with small and caducous stipules. Flowers are hermaphroditic and actinomorphic; the calyx has 5 sepals united at the base, "NOT" accompanied by an epicalyx (involucel). The corolla has 5 free petals and an androecium of numerous stamens, typically with free filaments "NOT" fused in a staminal tube (column). The pollen is smooth and the ovary superior and pluricarpellate. Fruits are schizocarpous or capsular.
Grewioideae is a subfamily of the family Malvaceae and was first described by Hochreutiner. The group is named after its type genus, Grewia, which is named for the English scientist Nehemiah Grew (1641-1712). It contains a number of genera that were previously placed in the defunct family Tiliaceae.
Helicteroideae is a subfamily of the family Malvaceae. Some taxonomists place genera in Helicteroideae in distinct families Durionaceae and Helicteraceae, while others recognizes the tribes Durioneae and Helictereae.
Sterculioideae is a subfamily of the family Malvaceae containing evergreen and deciduous trees and shrubs.
Jaques Étienne Gay was a Swiss-French botanist, civil servant, collector and taxonomist. His name is associated with plants in standardised botanical nomenclature, e.g. Crocus sieberi J.Gay. He was the most famous of the students of botanist Jean François Aimée Gaudin with whom he began collecting plants at the age of 14. He was married to Rosalie Nillion.
Malveae is a tribe of flowering plants in the mallow family Malvaceae, subfamily Malvoideae. The tribe circumscribes approximately 70 genera and 1040 species and has the greatest species diversity out the three tribes that make up Malvoideae. The flowers of Malveae are five-merous with a characteristic staminal column, a trait found throughout Malvoideae. Although there are not many economically important species within Malveae, the tribe includes Althaea officinalis, otherwise known as the Marsh Mallow.
Byttnerioideae is a subfamily of the flowering plant family Malvaceae.
Oskar Eberhard Ulbrich was a German botanist and mycologist.
Durioneae is a tribe within the subfamily Helicteroideae of the plant family Malvaceae s.l. The tribe contains at least five genera, including Durio, the genus of tree species that produce Durian fruits.
Pterocymbium tinctorium is a tropical forest tree species in the family Malvaceae: in the subfamily Sterculioideae. In Vietnam it is known as dực nang nhuộm and in Indonesia it is called kelumbuk, where it is a significant timber tree growing to about 25 m high.
