Borovichev E.A. Botanical excursion on the Northern Soroya. Hammerfest, 2014.

Sparse cover o fBog-bean (Menyanthes trifoliate) emerges on the shores o fshallow lakes and starts formation o fwetland vegetation, or 'hydrosere' about the plant (its appearance, characteristics, resemblance to other plants or even animals, etc.), others were given in the honor o f some real or mythological (more often antique or pagan) personage. For example, the Latin name of Cloudberry, plant o f county Finnmark (Rubus chamaemorus) consists o f its genus name Rubuš, which is derived from the Latin ‘ruber’ (red). The species name ‘chamaemorus’ is constructed by two Greek words - ‘chamai’ (on the earth) and ‘moron’ (Morus, Mulberry) and is descriptive o f both the shape o f leaves and the dwarf growth form. Sometimes, scientific names o f plants could be changed due to new taxonomical data. As a result, scientific names could vary in different publications. In this book we adopted scientific names used in Den nya nordiska floran (2003) by B. Moosberg and L. Steinberg for When plants start to occupy stony substrata, such succession o fvegetation is called 'Uthosere ’ Sea Lyme Grass (Leymus arenarius) is a pioneering species, one o fthefirst plants appearing on sandy substrata on the Soreya. It starts the succession called psammosere ’ flowering plants, from Checklist o f Norwegian Bryophytes by Frisvoll et al. (1995) for mosses, and from Lichen-forming and lichenicolous fungi ofFennoscandia by Santesson et al. (2013) for lichens. The vegetation is not a chaotic combination o f plants and lichens. Starting with bare surface o f land, plant associations succeeded one another until eventually a sort o f equilibrium was reached and certain kinds o f plant assemblages Mountain birchforests occur in valleys and in the lower parts o fmountain slopes. Trees’trunks are twisted due to snow-pressure and snow-creep in winter and early spring 23
