Emmotum is a genus of flowering plants in the family Metteniusaceae. It was formerly placed in the family Icacinaceae. It has about 13 species. One of these species, E. harleyi, was described in 2007.Rodrigo Duno de Stefano, Diego F. Angulo, and Fred W. Stauffer. 2007. "Emmotum harleyi, a New Species from Bahia, Brazil, and Lectotypification of Other Icacinaceae". Novon 17(3):306-309.
Description 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.
Taxonomy The type species for Emmotum is E. fagifolium W. Hamilton.
Emmotum is divided into two sections: Emmotum and Brevistyla. Section Brevistyla comprises four species and had formerly been treated as a separate genus.
Emmotum was named by Desvaux and Hamilton (1783–1856) in 1825.Emmotum At: International Plant Names Index. (See External links below).William Hamilton. 1825. Prodromus Plantarum Indiae Occidentalis:29. (See External links below) 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.Frederick Lens, Jesper Kårehed, Pieter Baas, Steven Jansen, David Rabaey, Suzy Huysmans, Thomas Hamann, and Eric Smets. 2008. "The wood anatomy of the polyphyletic Icacinaceae s.l. and their relationships within asterids". Taxon 57(2):525-552. These genera are: Calatola, Ottoschulzia, Oecopetalum, Poraqueiba, Emmotum, and Platea. Platea is native to Asia, while the others are from the New World.Rodrigo Duno de Stefano and Germán Carnevali Fernández-Concha. 2011. "Morphology-inferred phylogeny and a revision of the genus Emmotum (Icacinaceae)". Annals of the Missouri Botanical Garden 98(1):1-27. In the past, a separate family Emmotaceae was established with two genera, both having three carpels. pages 842 and 843 The APG IV system places this group in the family Metteniusaceae.
