 ceolatum, Hesperis aprica*, various Astragali, Oxytropis setosa. 

 Aster alpinus, Centaurea sibirica, Prenanthes diversifolia 

 (n. sp.), and Ephedra monastachya. On the above-mentioned 

 meadow-plain, grew to the height of a man, some Heraclea, 

 Seseli athamanthoides, Cirsium heterophyllum, Silybum cernuum, 

 Achillea impatiens, several Adenophora, Delphinia, and Aconita, 

 many Veratra and Thalictra, with Senecillis glauca, Trago- 

 pogon orientalis, Pedicularis data, and the beautiful P. pro- 

 boscidea, that covers large tracts. 



Among the peculiar bog-plants of this region, I mention 

 Androsace filiformis, Viola (tricolor is, aff.). Ranunculus Cymba- 

 laria, longicaulis (n. sp.), natans (n. sp.), Gentiana barbata, 

 Cirsium Gmelini, Potentilla multijida. Allium uliginosum 

 (n. sp.); and where the ground is shaded by shrubs or low 

 copsewood, we find Primula sibirica, Phaca exaltata, Pedicu- 

 laris speciosa, and others. Where the vallies expand, in 

 consequence of the rivers that water them being swollen by 

 the junction of other streams, as the valley of Tscharysch, in 

 the district where it receives the Kerlyk, and the vale of the 

 Koksun, at the confluence of the northern Abai; there, 

 between the river and the mountain that bounds the vale, 

 are extended flat, steppe-like plains, similar to those found 

 at the foot of the mountains, but with less luxuriance of 

 vegetation, and different from them in their peculiar pro- 

 ductions. In such spots grow Convolvulus Ammani, Gentiana 

 Gebleri, Potentilla (n. sp. subacauli, aff.) Saussurea (n. sp.), 

 Pencedanum vaginatum (n. sp.), which, in dry places, is only 

 a few inches high, Aster altaicus, J^eronica incana, Alyssum
