Some of the most interesting macrofossils found in the sediments of this area are the remains of cold-tolerant Betula nana
Jundzill indicated: "We found very rare species and species which have never been found before, such as Callitriche intermedia, Circaea alpina, Circaea intermedia, Calamagrostis schleicheri, Koeleria cristata, Sesleria caerulea, Scirpus caricinus, Primula farinosa, Salsola kali, Chenopodium villosum, Ribes alpinum, Swertia perennis, Lunaria rediviva, Alyssum montanum, Cakile maritima, Dentaria bulbifera, Taxus baccata, Betula nana
, Myrica and many other cryptogams".
Evidently, the planet is some size and despite the acreage of small leaved Betula nana
consumed by reindeer, the fellow in the pillar box red tunic wouldn't finish his shift were it not for those generous helpers that parents, aunts and uncles, brothers and sisters, so visibly are.

Leaves of Betula nana
x pubescens were approximately twice as asymmetrical as either of the parental taxa [ILLUSTRATION FOR FIGURE 2 OMITTED].
The pollen production of local taxa is very low, among which Betula nana
, Salix, Selaginella selaginoides, Dryas octopetala and steppe xerophytes Eurotia ceratoides, Ephedra and halophilous taxa Kochia prostrata, Salsola kali and Salicornia herbaceae have been identified (Pirrus 1971).
Unfortunately, in our diagram, the pollen of Betula nana
and the other Betula species have not been calculated separately.
Unattached Betula nana
roots were recognized by the presence of ectomycorrhizal roots, since the only other species in the community that is ectomycorrhizal, Salix pulchra, was very uncommon at our site (see Results).
Within each 5 X 5 m plot, the percent cover of Betula nana
, Cladina mitis, C.
makes up 8% and Alnaster 2% in layer VIII.
This is in a marked contrast to the often luxuriant Betula nana
heaths on the warm, west-facing slopes of Schuchert Dal below the Pass.
Here, we present data for the four major vascular plant species (Eriophorum vaginatum, Betula nana
, Ledum palustre, and Vaccinium vitis-idaea).
