Oryza coarctata: the name that best reflects the relationships of Porteresia coarctata (Poaceae: Oryzeae)

Oryza coarctata: the name that best reflects the relationships of Porteresia coarctata (Poaceae: Oryzeae)

Nordic Journal of Botany 23(5): 555-558

Oryza coarctata is a herbaceous species that serves as an important source of germplasm for salt tolerance in rice breeding. Despite biosystematic and phylogenetic studies showing that its closest relatives are other species of Oryza, many taxonomists continue to place it in the monospecific genus Porteresia because it is morphologically and ecologically distinct from other species of Oryza. Such a treatment obscures the reality of its genetic similarities to Oryza.
