Alei are also covered with trees, exclusive of the Fir tribes, 
and the same is probably the case with the other small rivers. 
The Uba and Ulba, however, where they have their course 
beyond the mountain, are, so far as I have seen, unadorned 
with wood; and, in general, the greater portion of this wide 
steppe tract, with the exception of the above-mentioned Pine 
forest, that extends almost uninterruptedly from Barnaul to 
Schulbinsk, is entirely barren of trees; but farther north, 
there is no deficiency of them. In these steppes occur many 
plants that grow plentifully in Europe, particularly the fol- 
lowing ;— Adonis vernalis and Anemone patens, both in great 
abundance; many species of Artemisia, Allium, Gypsophila, 
and Statice, numerous Umbellate ; Ceratocarpus arenarius 
. Diotis ceratoides cover whole tracts; and where the ground is 
impregnated with saline principle, the peculiar salt-plants 
occur in abundance, such as the species of Polycnemum, 
Atriplex, Chenopodium, Frankenia, Tamarix, Salicornia, and 
Halocnemum ; also Chorispora sibirica, Diotis atriplicoides 
and others. Farther to the south, Amaryllis tatarica is 
extremely plentiful, with Zindera tetraspis, and the equally 
rare Nepeta sibirica ; and the beautiful Eremurus growing 0n 
the little hills. , But the peculiar richness of the Flora of this 
steppe first displays itself in the neighbourhood of the Irtysch, 
and on its left bank, especially in the tract of the Noor Saisans 
where, besides most of the above-named plants, the following 
deserve to be particularly noted:—a new species of Peplis 
and of Camphorosma ; many individuals, quite peculiar to this 
VU, belonging to the genera Cachrys, Peucedanum and 
Seseli ; among the Asperifolie, the genera Echinospermum
