Three species (
G. odorata, G. scabra, G. speciosa) are known in
cultivation.
Guettarda argentea provides edible fruit.
Guettarda was
named by
Linnaeus in 1753 in his book
Species Plantarum. This
generic name is in honour of the 18th century
French naturalist Jean-Étienne Guettard. 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. ==Species==
