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

 plants arc sfill to be found as the last remains of the reccdinj^ taif<a: 



Aconitum laeve, Veralrum album, Equiseium siluaticum. Aclaea spicala var. 

 erytlirocarpa. Majanthemum bifolium, Trientalis europaea. Circaea alpina, Heracleum 

 dissectum, Linnaea borc(dis. Pfirola minor. Pedicularis uncinala. Lijcopodium clavatum, 

 Woodsia ilvensis. and AUuirium Filix femina. 



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



Belula pubescens. Populus tremula, Populus laurifolia. Populus nigra. Alnus frulico.sa, 

 Sorbus Aucuparia. Prunus Padu.s. Cornus alba, Crataegus sanguinea, Rosa acicularis, 

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



In di-y, sandy woods of larch and pine are to be seen: 



Draba nemorosa, Stellnria dichotoma var. heleropbglla. Scorzonera austriaca, Pgrola 

 roiundifolia var. inrarnata. Andiosaces seplentrionale, Cotoneasier melanocarpa, Sedum 

 purpureum. Bupleurum mullinervc. Bupleurum longifolium var. aureum. Saussurea 

 discolor, Mulgedium azureum, Hieracium umbellalum, Campanula glomerata, Zygadenus 

 sibiricus. Rhododendron parvifolium, Ledum paluslre var. angustiim, Vaccinium vitis 

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

 Serpyllum, Potentilla bi/urca. Veronica incana. Polygonum nndulatum var. alpinum, 

 Dracocephalum Riiy.schiana. Aster alpinus. Phleum Boehmeri subspec. decurtatum nov. 

 subspec. Triticum cristatum, and Poa allaica. 



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 barbalum. Cotyledon spinosa, Sedum hybridum. Statice speciosa, Artemisia 

 glauca, Potentilla vi.scosa, Potentilla chrysantha, Potentilla subacaulis, Coluria geoides. 

 Scabiosa ochroleuca, Caragana pygmaea, and Atrapha.vis frulescens. 



This floral association, i-estricted 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
