A new population of D. tristachyum found on sandstone of the northern Vosges, is described. The population inhabited a thermophilic heathland frequently subjected to burning. The heathland association alternated with an acidophilic Luzulo-quercetum association, and with the association Daphno cneori-Callunetum (Stachys officinalis mesohydric subassociation). The distribution of D. tristachyum, D. X zeilleri and D. complanatum in the Vosges mountains is discussed.
