Salicion callicarpeae Daniëls in Mucina et al. 2016
vir04 | This new alliance comprises thickets and low shrub vegetation of willows in the lowlands of subarctic and low-arctic Greenland characterised by (sub)oceanic climate, confined to wind-sheltered, relatively warm and sunny sites on level ground and footslopes, and supported by sandy-gravelly, acidic, dry or temporary moist, mineral soil. The holotypus (hoc loco) of this alliance is the Festuco-Salicetum callicarpaeae Daniëls 1982 (Daniëls 1982: 31 et seq.). I consider the name Salicion callicarpeae as more appropriate than the earlier, invalidly published Pyrolo grandiflorae-Salicion callicarpeae (Daniëls in Bœuf et al. 2014: 116). The diagnostic taxa of the alliance are: Alchemilla glomerulans, Anemone richardsonii, Bistorta vivipara, Campanula rotundifolia, Carex bigelowii subsp. bigelowii, Cerastium alpinum, Epilobium angustifolium, Festuca rubra, Gnaphalium norvegicum, Hieracium hyparcticoides, H. laevigatum, H. lividorubens, Lycopodium annotinum, Orthilia secunda, Pyrola minor, Ranunculus acris, Salix glauca subsp. callicarpaea and Stellaria calycantha. (F. Daniëls).
