. The vegetation of the Siberian-Mongolian frontiers (the Sayansk region). Botany; Botany. Similar open, dry declivities with southern aspects were rather frequently to be met with in the taiga, often bearing marks of forest-fires, which had devastated the wood. In these stretches the conifers seemed to have some difficulty in gaining ground again, foliferous trees being mostly predominant, especially Beiiila piibescens and Populiis iiemula, associated with various grasses and some forerunners of the xerophilous steppe- like flora. At greater altitudes on the summits of the still wooded hills to be found here at the outskirts of the Sayansk eruptive area, some plants not observed by me in the lower regions also occurred, viz.: Saxifraga sibirica. Euphorbia alpina. Anemone coerulea, Ranunculus propinquus, Viola biflora, Saussurea alpina, Betula rotundifolia, Petasites frigidus, and others. Moreover, the following are above all characteristic of the sandy stretches of the liver-bed: Dianthus superbus, Potentilla fruticosa, Potentilla anserina, and Equisetum variegatum, and in loamy soil Tussilago Farfara, and Veronica serpyllifolia. In low, irrigated, stony places and on low river-banks among pebbles, the charac- teristic leaves of Petasites laeuigatus frequently occurred at this time. The taiga is practically waste, untouched and uninhabited. Only at intervals of several days' journeys, the traveller meet with scattered camps of gold-diggers where. Fig. 29.
