Guettarda is a plant genus in the family Rubiaceae. Most of these plants are known by the common name velvetseed.
Most of the species are Neotropical. [1] Twenty are found in New Caledonia and one reaches Australia. [2] 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 18 m (59 ft) in height.
Three species (G. odorata, G. scabra, G. speciosa) are known in cultivation. [3] Guettarda argentea provides edible fruit. [1] The type species for the genus is Guettarda speciosa. [4]
Guettarda was named by Linnaeus in 1753 in his book Species Plantarum . [5] [6] This generic name is in honour of the 18th century French naturalist Jean-Étienne Guettard. [7]
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. [8]
Estimates of the number of species range from about 50 [3] to 162. [9] The following species list may be incomplete or contain synonyms.
