Abstract
The floristic analysis of the Mediterranean-Alpine moors of L. angustifolia and G. cinerea conducted in the maritime Alps leads to the distinction, from the viewpoint of phytosociology, of 2 types of groupings, succeeding in altitude. Between 700 and 1200 m elevation, is a "lavandiae" of the submediterranean type belonging to the order of the Rosmarinetalia (alliance of the Aphyllantion). In the middle basins of the Var and of the Tinee, it corresponds to a grouping of Artemisia alba Turra ssp. camphorata Vill. Between 1200 and 1750 m. elevation is a "lavandiae" of a mountain type belonging to the order of the Ononidetalia striatae (alliance of Ononidion striatae), principally represented, in the upper basins of the Var and of the Tinee, by an association of Thalictrum foetidum L. and Senecio doronicum L. ssp. eu-doronicum Brig, and Cav.
