Emmotum is a genus of flowering plants in the family Metteniusaceae. It was formerly placed in the family Icacinaceae. [1] [2] It has about 13 species. [3] One of these species, E. harleyi, was described in 2007. [4]
Emmotum is a genus of shrubs and trees. The flowers are small and white. The inner surface of the petals is conspicuously hairy. Emmotum has a 3-locular ovary.
The type species for Emmotum is E. fagifoliumW. Hamilton.
Emmotum is divided into two sections: Emmotum and Brevistyla. Section Brevistyla comprises four species and had formerly been treated as a separate genus.[ citation needed ]
Emmotum was named by Desvaux and Hamilton (1783–1856) in 1825. [5] [6] George Bentham described the genus Pogopetalum in 1841, but John Miers recognized that it was the same as Emmotum, described earlier. Because the earlier name has priority, Pogopetalum is no longer a correct name.
Emmotum belongs to an informal group of six genera known as the Emmotum group, that was formerly placed in family Icacinaceae. [7] These genera are: Calatola , Ottoschulzia , Oecopetalum , Poraqueiba , Emmotum, and Platea . Platea is native to Asia, while the others are from the New World. [3] In the past, a separate family Emmotaceae was established with two genera, both having three carpels. [8] [9] The APG IV system places this group in the family Metteniusaceae. [1]
Species include: [10]
Dioscoreaceae is a family of monocotyledonous flowering plants, with about 715 known species in nine genera. The best-known member of the family is the yam.
Scilla is a genus of about 30 to 80 species of bulb-forming perennial herbaceous plants in the family Asparagaceae, subfamily Scilloideae. Sometimes called the squills in English, they are native to woodlands, subalpine meadows, and seashores throughout Europe, Africa and the Middle East. A few species are also naturalized in Australasia and North America. Their flowers are usually blue, but white, pink, and purple types are known; most flower in early spring, but a few are autumn-flowering. Several Scilla species are valued as ornamental garden plants.
Haemodoraceae is a family of perennial herbaceous flowering plants with 14 genera and 102 known species. It is sometimes known as the "bloodroot family". Primarily a Southern Hemisphere family, they are found in South Africa, Australia and New Guinea, and in the Americas. Perhaps the best known are the widely cultivated and unusual kangaroo paws from Australia, of the two closely related genera Anigozanthos and Macropidia.
Ochnaceae is a family of flowering plants in the order Malpighiales. In the APG III system of classification of flowering plants, Ochnaceae is defined broadly, to include about 550 species, and encompasses what some taxonomists have treated as the separate families Medusagynaceae and Quiinaceae. In a phylogenetic study that was published in 2014, Ochnaceae was recognized in the broad sense, but two works published after APG III have accepted the small families Medusagynaceae and Quiinaceae. These have not been accepted by APG IV (2016).
In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade. Asterids is the largest group of flowering plants, with more than 80,000 species, about a third of the total flowering plant species. Well-known plants in this clade include the common daisy, forget-me-nots, nightshades, the common sunflower, petunias, yacon, morning glory, lettuce, sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, table herbs such as mint, basil, and rosemary, and rainforest trees such as Brazil nut.
Boraginales is an order of flowering plants in the asterid clade. It includes the Boraginaceae and a number of other families, with a total of about 125 genera and 2,700 species. Its herbs, shrubs, trees and lianas (vines) have a worldwide distribution.
Theophrastoideae is a small subfamily of flowering plants in the family Primulaceae. It was formerly recognized as a separate family Theophrastaceae. As previously circumscribed, the family consisted of eight genera and 95 species of trees or shrubs, native to tropical regions of the Americas.
Olof Peter Swartz was a Swedish botanist and taxonomist. He is best known for his taxonomic work and studies into pteridophytes.
The Icacinaceae, also called the white pear family, are a family of flowering plants, consisting of trees, shrubs, and lianas, primarily of the tropics.
Calatola columbiana is a species of flowering plant in the family Metteniusaceae. It was formerly placed in the family Icacinaceae. It is endemic to Colombia.
Calatola is a genus of flowering plants in the family Metteniusaceae. It was formerly placed in the family Icacinaceae. Its range is from Mexico to Peru. There are nine species. The type species is Calatola mollis.
Metteniusa is a genus of flowering plants in the family Metteniusaceae. It was named by Hermann Karsten in 1860 for the German botanist Georg Heinrich Mettenius. It has seven species. The type species is Metteniusa edulis.. "Metteniusaceae" was proposed by Adalbert Schnizlein and validated by Hermann Karsten in 1860.. The family is now placed in its own order, Metteniusales.
Cardiopteridaceae is a eudicot family of flowering plants. It consists of about 43 species of trees, shrubs, and woody vines, mostly of the tropics, but with a few in temperate regions. It contains six genera, the largest of which is Citronella, with 21 species. The other genera are much smaller.
Oncotheca is a genus of tree endemic to New Caledonia. There are two species, Oncotheca balansae and Oncotheca humboldtiana.
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".
Apodytes is a genus of flowering plants in the family Metteniusaceae. It was formerly either unplaced as to family or placed in the family Icacinaceae. It consists of about 8 species of evergreen trees, from tropical northeastern Australia, New Caledonia, Africa and Asia. The exact number of species has been revised from 3 to 8, according to The Plant List.
Metteniusaceae are a family of flowering plants, the only family in the order Metteniusales. It consists of about 10 genera and 50 species of trees, shrubs, and lianas, primarily of the tropics. The family was formerly restricted to just Metteniusa, but it is now expanded with a number of genera that were formerly placed in the widely polyphyletic Icacinaceae.
Amaryllidoideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG III, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae, and the others are Allioideae and Agapanthoideae. The subfamily consists of about seventy genera, with over eight hundred species, and a worldwide distribution.
Dendrobangia is a genus of flowering plants in the family Metteniusaceae. It was formerly placed in the family Cardiopteridaceae. It was described as a genus in 1896.
