D. x anglica growing in a hollow of a floating bog without any D.linearis seen nearbye.
D. anglica being a hybrid of D. linearis and D.rotundifolia that has undergone chromosomal doubling was already proposed by Winge (1917). The hybrid can be expected where the latter 2 species grow together, basically where D.linearis is found. But D. x anglica is rare because it is sterile. And it is frequently overlooked because it looks just like the fertile D.anglica (amphiploid) when not in fruit. Minor differences exist though. See the comprehensive article in Rhodora vol.57 by Wood (1955) for a full description. Schnell (1999) published his view on differentiating the hybrid from the species in CPN. To make it a bit more complicated you should remember that there is also the sterile hybrid D. x obovata (D.anglica x rotundifolia) which can be confused with D.anglica and especially with D. x anglica.
