At the close of the glacial period the alpine floras retreated to the mountains accompanied by an arctic contingent, though doubtless many species of the latter, such as Salix polaris, failed to establish themselves.
The following species, none of which are found in European Russia, are characteristic of the tundras - arbutus (Arctostaphilus alpina), heaths or andomedas (Cassiope tetragona and C. hypnoides), Phyllodoce taxifolia, Loiseleuria procumbens, a species of Latifolium, a Polar azalea (Osmothamnus fragrans) and a Polar willow (Salix arctica).
Mimosa and the wild wilge-boom (Salix capensis) are the common trees on the banks and rivers, while the weeping willow is frequent round the farmsteads.

Thus the galls of Cynips and its allies are inhabited by members of other cynipideous genera, as Synergus, Amblynotus and Synophrus; and the pine-cone-like gall of Salix strobiloides, as Walsh has shown, 2 is made by a large species of Cecidomyia, which inhabits the heart of the mass, the numerous smaller cecidomyidous larvae in its outer part being mere inquilines.
With the melting of the great ice-sheet the climate became milder, and the southern part of Sweden was covered with shrubs and plants now found only in the northern and alpine parts of the country (Salix polaris, Dryas octopetala, Betula nana, &c.).
Of Phanerogams, only the Dryas octopetala covers small areas of the debris, interspersed with isolated Cochlearia, &c., and, where a layer of thinner clay has been deposited in sheltered places, the surface is covered with saxifrages, &c.; and a carpet of mosses allows the arctic willow (Salix polaris) to develop. Where a thin sheet of humus, fertilized by lemmings, has accumulated, a few flowering plants appear, but even so their brilliant flowers spring direct from the soil, concealing the developed leaflets, while their horizontally spread roots grow out of proportion; only the Salix lanata rises to 7 or 8 in., sending out roots I in.
Briancon manna is met with on the leaves of the common Larch, and bide-khecht on those of the willow, Salix fragilis; and a kind of manna was at one time obtained from the cedar.
