Grassy-sphagnum marshes. Distributed within upper regions which remain unaffected during flooding. These marshes are formed on dom-shaped thick layers of peat (between Paliastomi lake and rivers Imnati and Tkhorina near Kobuleti). Six dominant species of bog moss are presented here. In difference with northern upper marshes, in northern latitude, sphagnum mosses, in Kolkheti do not form uniform cover, but combine with common species of marshes. Except sphagnum mosses here are presented other boreal lands: peatlands Carex, Drosera, Menyanthes trifoliata; also, southern plants are usual: Azalea pontica, Rhododendron ponticum. Such combination makes these marshes unique.
Scrub-grass marshes. In difference of grassy marshes here in hummocks can be found scrubs, first of all Alnus barbata, usually smilax excelsa, also Pterocarya, Vibrunum, Frangula etc. Marshy grasses grow between hummocks.
Alnus-woody marshes. Wide spread in river-beds of old streams, on coastal lowland and in other marshy places with peaty soils. They look monotonous in general view. Alnus barbata makes a high tussocks on which other arboreal species are rarely presented-Pterocaria, Carpinus, Querqus, Ulmus and Scrubs-Viburnum, Sambucus, Crataegus, Ruscus ponticus etc. Many lianas are presented. On swamps between Shummocks and on personal hummocks there is an abundance of marsh vegetation: Carex, Juncus, Mentha aquatica etc, also adventative forms: grasses-Pollinie; Carex-Cypreus; other grasses-Polygonum. Most of them where recently.absent here.
