摘要：
Taxonomy of the genus Echinodorus is partially revisited in the light of current understanding of the phylogenetic relationships of the genus. As a result of new taxonomy, the species status of some previously synonymised taxa are restored, other names are synonymised, and some nomenclatural problems unnoticed by previous authors are resolved. Two new species, Echinodorus reptilis and E. emersus are described. The subgeneric divisions of the genus are not accepted, and all subspecific taxa are either rejected or established as species. As a result, 28 species based on a phylogenetic species concept are now recognised in Echinodorus and an identification key to these species is provided. © 2008 The Board of Trustees of the Royal Botanic Gardens, Kew.
