Saxifrago-Ranunculion nivalis Nordhagen 1943
(3b)
– thl06 This unit, often used at the level of an alliance, has been described as a suballiance of the Ranunculo-Oxyrion; it was also described invalidly since only sociations and 'provisional' associations were assigned to the 'Saxifrago-Ranunculion nivalis' in the Nordhagen’s (1943) protologue. (M. Chytrý, L. Mucina).
