Werth1& David B. Lellinger2 Summary Werth, C. R. & Lellinger, D. B.: Genomically preserved plants and their nomenclature. - Taxon 41: 513-521. 1992. - ISSN 0040-0262. Species that hybridize to form allopolyploids may become extinct, yet may be discovered and characterized through the continued existence and expression of their genomes in their allopolyploid descendants. For purposes of nomenclature, these genomically preserved plants (GPPs) form a third category of plants, along with recent plants and fossils, with which they share certain kinds of characters. GPPs are essential to understanding the phylogeny of some species complexes and can be included as OTUs in phenetic and phylogenetic analyses.
