We have studied the morphological and anatomical structure of Anthemis caucasica Chandjian – theendemic of alpine zone of the Caucasus. The plant is characterized by protection from hard ultraviolet radiation, a largesupply of nutrients, moderate growth and flowering. Horizontally lying rhizomes are optimal for occupying highly stonyareas with low competition.

The relationship between the life form and distribution of cereals, sedges and Lusula spicata (L.) DC. in theAlpine lichen tundra association was revealed. The dependence of plants to forms of relief and certain ecological nicheswas studied. Within the framework of the carousel model (van der Maarel, Sykes, 1993) their occurrence and the speedof the small-scale turnover in the community were estimated.
