''Guettarda'' is a plant genus in the family Rubiaceae. Most of these plants are known by the common name Velvetseed. Estimates of the number of species range from about 50 〔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. ISBN 978-0-333-47494-5 (set)〕 to 162.〔''Guettarda'' At: World Checklist of Rubiaceae At: Kew Gardens Website. (see ''External links'' below).〕 Most of the species are neotropical.〔David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008). Cambridge University Press: UK. ISBN 978-0-521-82071-4〕 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. Three species (''G. odorata, G. scabra, G. speciosa'') are known in cultivation.〔 ''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).〕 It is a tree of coastal habitats, up to in height. It is grown as an ornamental. ''Guettarda'' was named by Linnaeus in 1753 in his book ''Species Plantarum''.〔''Guettarda'' in International Plant Names Index. (see ''External links'' below).〕〔Carolus Linnaeus. 1753.

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. ISBN 978-0-8493-2676-9. (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.
