Taxonomic Notes
Potamogeton nodosus is one of the most polymorphic Potamogeton species, showing several distinct morphotypes as well as an extreme phenotypic plasticity throughout its range. It seems likely that there has been some confusion about the distinction between this specie and others such as P. linguatus, P. ferrugineus, P. tepperi and P. sulcatus (Wiegleb and Kaplan 1998), to the extent that this evaluation could include information on some of all of those taxa. Potamogeton nodosus has been shown to hybridise with P. natans (P. xschreberi G. Fisch.), the hybrid is not common and is unlikely to affect the survival of the species or this evaluation.
Taxon distribution as listed in assessment
The species was listed without detail for the UAE by Jongbloed et al. (2003). The first record found for the species in the country dates from 1857 (<a href=""https://herbarium.univie.ac.at/database/detail.php?ID=162724"">Herbarium, Institute of Botany, University of Vienna</a>). There are no detailed distribution data available for this species within the UAE. Globally, the native range of this species spans across the Americas, European continent, Africa, temperate and tropical Asia in addition to Australasia (Board of Trustees, RBG Kew 2019).
