Hygrohypnetalia Krajina 1933
pla01 | Drehwald & Preising (1991) typified the name Hygrohypnetalia Krajina 1933 with the Hygrohypnion dilatati Kraijna ex Plămăda 1974. This choice is illegitimate as the original diagnosis of the order contains the two alliances Hygrohypnion dilatati and Andreaeion nivalis (ICPN art. 19). Marstaller (2006) choose the former alliance and this choice must be followed. (H. Bültmann).
