Guettarda is a plant genus in the family Rubiaceae. Most of these plants are known by the common name velvetseed.
Distribution Most of the species are Neotropical.David J. Mabberley. 2008. Mabberley's Plant-Book third edition (2008). Cambridge University Press: UK. Twenty are found in New Caledonia and one reaches Australia. A few others are found on islands and in coastal areas of the Indian and Pacific Oceans. It is a tree of coastal habitats, up to in height.
Taxonomy Three species (G. odorata, G. scabra, G. speciosa) are known in cultivation.Anthony J. Huxley, Mark Griffiths, and Margot Levy (editors). 1992. The New Royal Horticultural Society Dictionary of Gardening. The Macmillan Press Limited, London; The Stockton Press, New York. (set) Guettarda argentea provides edible fruit. The type species for the genus is Guettarda speciosa.Guettarda In: Index Nominum Genericorum. In: Regnum Vegetabile (see External links below).
Guettarda was named by Linnaeus in 1753 in his book Species Plantarum.Guettarda in International Plant Names Index. (see External links below).Carl Linnaeus. 1753. Species Plantarum (Species plantarum : exhibentes plantas rite cognitas ad genera relatas, cum differentiis specificis, nominibus trivialibus, synonymis selectis, locis natalibus, secundum systema sexuale digestas / Caroli Linnæe.): 2:991. Holmiae: Impensis Laurentii Salvii: Stockholm, Sweden. (see External links below). This generic name is in honour of the 18th century French naturalist Jean-Étienne Guettard.Umberto Quattrocchi. 2000. CRC World Dictionary of Plant Names volume II. CRC Press: Boca Raton; New York; Washington, DC; USA. London, UK. . (vol. II).
The genus Guettarda is much in need of revision. Molecular phylogenetic studies have found it to be several times polyphyletic with some of its clades paraphyletic over small genera.Ulrika Manns and Birgitta Bremer. 2010. "Towards a better understanding of intertribal relationships and stable tribal delimitations within Cinchonoideae s.s. (Rubiaceae)". Molecular Phylogenetics and Evolution 56(1):21-39.
Species Plants of the World Online currently accepts 145 species, which are listed below. Other estimates of the number of species range from about 50 to 162.Guettarda At: World Checklist of Rubiaceae At: Kew Gardens Website. (see External links below).
