Bromus inermis, Beckmannia eruciformis, Carex Arnelli, Geranium pseudosibiricum, 

 Erodium Stephanianum, Medicago platycarpa, Potentilla fruticosa, Artemisia vulgaris, 

 Pleurospermum austriacum, Cacalia haslaia, Galium vernum, Anemone silvestris, Serralula 

 coronata, Gampanula Gervicaria, Luzula campeslris, Dactylis glomeraia, Botrychiiim 

 Matricariae, Geum Aleppicum, Lampsana communis, Rubus saxatilis, Rubus idaeus, 

 Agrimonia pilosa, Goodgera repens, Pulmonaria moUissima, Anthriscus silvestris, 

 Scutellaria scordiifolia, and Ulmaria pentapetala. 



Of the typical wood flora, which has been considerably decimated, the following 

 plants are still to be found as the last remains of the receding taiga: 



Aconitum laeve, Veratrum album, Equisetum silvaticum, Actaea spicata var. 

 ergthrocarpa, Majanthemum bifolium, Trientalis europaea, Gircaea alpina, Heracleum 

 dissectum, Linnaea borealis, Pgrola minor, Pedicularis uncinata, Lgcopodium clavatum, 

 Woodsia ilvensis, and Athyrium Filix femina. 



Of foliferous trees I have observed here at Ust Sisti-kem: 



Betula pubescens, Populus tremula, Populus lauri folia, Populus nigra, Alnus fruticosa, 

 Sorbus Aucuparia, Prunus Padus, Gornus alba, Grataegus sanguinea, Rosa acicularis, 

 Ribes nigrum, Ribes pubescens, Lonicera coerulea var. glabrescens. 



In dry, sandy woods of larch and pine are to be seen: 



Draba nemorosa, Stellaria dichotoma var. heterophylla, Scorzonera austriaca, Pgrola 

 rotundifolia var. inrarnata, Andiosaces seplentrionale, Gotoneaster melanocarpa, Sedum 

 purpureum, Bupleurum multinerve, Bupleurum longifolium var. aureum, Saussurea 

 discolor, Mulgedium azureum, Hieracium umbellatum, Gampanula glomerata, Zggadenus 

 sibiricus, Rhododendron parvifolium, Ledum palustre var. angustHm, Vaccinium vitis 

 idaea, Viola arenaria, Dianthus chinensis, Gentiana verna var. angulosa. Thymus 

 Serpyllum, Potentilla bifurca, Veronica incana, Polygonum undulatum var. alpinum, 

 Dracocephalum Rugschiana, Aster alpinus, Phleum Boehmeri stibspec. decurtatum nov. 

 subspec, Triticum cristatum, and Poa altaica. 



Besides some of the plants already mentioned, the following, which are to be found 

 here especially on dry, hot declivities and hills with southern aspects, may also be 

 particularly noted, representing the genuine steppe flora pushing forward here: 



Aconitum barbatum, Gotyledon spinosa, Sedum hybridum, Statice speciosa, Artemisia 

 glauca, Potentilla viscosa, Potentilla chrysantha, Potentilla subacaulis, Goluria geoides. 

 Scabiosa ochroleuca, Garagana pygmaea, and Atraphaxis frutescens. 



This floral association, restricted by Ust Sisti-kem only to the dry and hot 

 slopes with southern aspects, is, for the rest, gradually more widely and richly distributed 

 farther to the south. 



Proceeding farther southwards the climate becomes gradually still drier; the 

 moist taiga, which, as already mentioned, was seen to form small forests as far as Ust 

 Sisti-kem, practically disappears, the larch alone becoming the dominating conifer. 

 Open, steppe-like plains are more frequent and become gradually larger, and the flora 

 contains a constantly increasing number of steppe plants. It is interesting in these
