It was first described by Lansdown & Ruhsam in 2022.[1]
Natural hybridisation
Hybridisation occurred after introduction of the non-native Nuphar advena to Great Britain. It hybridised with the native species Nuphar lutea and formed the new hybrid Nuphar × porphyranthera.[2]
Type specimen
The type specimen was collected from a shaded former gravel pit beneath trees in Ferry Lane, Shepperton, Middlesex, United Kingdom.[2][3]
Ecology
Habitat
It occurs in ornamental ponds, and in a gravel pit.[2] It doesn't appear to spread into new habitats.[4]
