''Duboscia'' is a small plant genus, with two species, in the family Malvaceae. The genus occurs from the Ivory Coast to the Democratic Republic of Congo. The genus was previously in the Tiliaceae, under the Angiosperm Phylogeny Group, APG classification it is now placed in the Malvaceae. The genus was first described by Henri Théophile Bocquillon in 1866.Bocquillon, H. T. in Baillon, H.

Duboscia Viridiflora
''Duboscia viridiflora'' occurs from the Ivory Coast to the Democratic Republic of Congo. It is a tree which grows to 25m, and often has a deeply fluted trunk. The leaves and young stems are covered in sparse, stellate hairs. The flowers are pale green-white, with bracts below. The fruits are ribbed and very fibrous. The species was first described by Karl Moritz Schumann in 1897, where he placed it in the genus ''Diplanthemum''. It was moved to the genus ''Duboscia'' by Johannes Mildbraed, Gottfried Wilhelm Johannes Mildbraed in 1922.Mildbraed, G. W. J.

Duboscia Macrocarpa
''Duboscia macrocarpa'' occurs from Nigeria to the Democratic Republic of Congo. It is a tree which grows to 30 m, and often has a fluted trunk. The leaves and young stems are covered in dense hairs. The flowers are pink-reddish brown, with bracts below. The fruits are ribbed and very fibrous. The species was first described by Henri Théophile Bocquillon Henri Théophile Bocquillon (5 June 1834, Crugny – 15 May 1884, Paris) was a French botanist.

Henri Théophile Bocquillon
Henri Théophile Bocquillon (5 June 1834, Crugny – 15 May 1884, Paris) was a French botanist. In Paris, he successively worked as an instructor at the Lycée Napoleon (from 1858), Lycée Louis-le-Grand (from 1862), Lycée Henri-IV (from 1864) and Lycée Fontanes (from 1867). At the latter two schools he served as chair of natural sciences. In 1862 he obtained his doctorate in natural sciences, and in 1866, he received his medical doctorate. In 1869 he became an associate professor to the faculty of medicine at Paris. He was a member of the Société botanique de France and a chevalier of the Légion d'honneur. He was the taxonomic authority of the genera '' Baillonia'', '' Duboscia'' and '' Desplatsia''.

Tiliaceae
Tiliaceae () is a family of flowering plants. It is not a part of the APG, APG II and APG III classifications, being sunk in Malvaceae mostly as the subfamilies Tilioideae, Brownlowioideae and Grewioideae, but has an extensive historical record of use. All through its existence the family has had a very lively history, with various authors taking very different views on what should be part of this family. As a result, it is recommended when this name is encountered to check what the author means. However, in the northern temperate regions the name is unambiguous as the only representative is '' Tilia'', the lime or linden. APG II system The APG II system, does not recognise this as a family but submerges it in the Malvaceae sensu lato, which unites the four families Bombacaceae, Malvaceae sensu stricto, Sterculiaceae and Tiliaceae. Modern botanical taxonomy, such as the relevant volume in the Kubitzki series which conforms to APG, treats most of the plants that traditionally c ...

Grewioideae
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. Description Within the Malvaceae, this subfamily has its inflorescences opposite the leaves, the corollas are usually clawed, and there is a nectar-bearing hair carpet at the base of the petals and there are numerous dithecal stamens. The fruit is fleshy or capsular with spines, and the seeds are winged. The group is thought to have originated about 42 (± 15) million years ago. Taxonomy Ulrike Brunken & Alexandra Muellner divide the Grewioideae into two clades, the Grewia clade, Grewieae Endl. and the Apeiba clade, Apeibeae Benth., on the basis of morphological and molecular evidence. Tribes and genera The subfamily includes the following genera - accepted by Bayer & K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvaceae
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 ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), ''Sterculia'' (250 species), ''Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae '' sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely allie ...

Angiosperm Phylogeny Group
The Angiosperm Phylogeny Group (APG) is an informal international group of systematic botanists who collaborate to establish a consensus on the taxonomy of flowering plants (angiosperms) that reflects new knowledge about plant relationships discovered through phylogenetic studies. , four incremental versions of a classification system have resulted from this collaboration, published in 1998, 2003, 2009 and 2016. An important motivation for the group was what they considered deficiencies in prior angiosperm classifications since they were not based on monophyletic groups (i.e., groups that include all the descendants of a common ancestor). APG publications are increasingly influential, with a number of major herbaria changing the arrangement of their collections to match the latest APG system. Angiosperm classification and the APG In the past, classification systems were typically produced by an individual botanist or by a small group. The result was a large number of systems ( ...

Flora Of Africa
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
