Taxonomy
Taxonomic history
It was first described as Nymphaea thermalis DC. in 1821. Later, it was reduced from the species status to the variety Nymphaea lotus var. thermalis (DC.) Tuzson in 1907. In the following year another name, Castalia thermalis (DC.) Simonk., was published. The accepted name is Nymphaea lotus var. thermalis (DC.) Tuzson.[1]
Disputation of status as separate taxon
Some sources believe it is a relict, which had survived the ice age due to warm water from the thermal spring in Romania.[6] DNA analyses came to the conclusion, that Nymphaea lotus var. thermalis is not distinct from Nymphaea lotus and cannot be a relict population.[7] It was primarily separated for geographical reasons.[8]
