Abstract. We study adaptation features of Stellaria humifusa (Caryophyllaceae) on the rocky ecotopes of the west coast of Svalbard. Stellaria humifusa, a mat-forming herb, is a monodominant plant community. In this paper we show that the mat life form is a complex structure, which is represented by a system of aboveground and underground organs, and a soil horizon. Aboveground organs are the top layer of the dead plants from the previous year. Flowering shoots of the current year plants with white flowers can be seen on the ground surface. The next layer of the mat is organogenic, which the main assimilating system. The layer is represented by the green leaves of Stellaria humifusa, which by their anatomical structures and functional indicators are adapted to the local habitat conditions in the mat. The bottom layer is the organomineral horizon. The layer represents a soil substrate, which is a source of mineral nutrition for the entire structure. The chemical composition of the soil substrate of the mat Stellaria humifusa is similar to the natural soil profile of the coastal area. The plant mat contributes to a greater accumulation of organic matter, activates humification and provides favorable conditions for the growth of Stellaria humifusa.
