 Sisymbrium micrantlmm (n. sp.), Ballota lanata, several kinds 

 ol Leontodon^ and, according as the soil is more or less salt, 

 Glaux maritima, which frequently densely covers the ground, 

 and the other formerly-enumerated saline plants. 



From 4,500 to an elevation of 6,500 Parisian feet, where 

 Pinus Cembra marks the highest present boundary of the 

 growth of trees, the Europaean species gradually diminish 

 to give place to the Flora of the Altai. Here grow most of 

 the individuals of the genus Pedicularis, Sanguisorba alpina 

 (n. sp.). Primula nivalis, Veronica densifiora (n. sp.), Gentiana 

 altaica, angulosa, glacialis, humilis and septemjida, Swertia 

 obtusa (n. sp.), Athamanta compacta (n. sp.), Linum sibiricum, 

 Lonicera hispida. Primula Pallasii, Viola altaica, unijlora 

 and pinnata, Juncus triglumis, Epilobium alpinum, Cerastium 

 alpinum, Saxifraga Hircidus, Mespilus unijlora (n. sp.), 

 Potentilla macrantha (n. sp.), Aquilegia glandulosa, Ranunculus 

 altaicus, Anemone narcissijlora, Dracocephalum altaiense, 

 Linncea borealis, Phlomis alpina, Cochlearia integrifolia, Macro-

 altaicum, Erigeron alpinus, Frolovia lyrata (n. sp.), Leuzea 

 altaica, Saussurea pycnocephala (n. sp.), a number of Willows, 

 &c. The most central of these extended steppes, near the 

 Tschuja, which rise one above another like terraces, and the 

 highest of those which Bunge visited, situated towards the 

 western or lower end, at an elevation of 5,759 Parisian feet, is 

 still more distinguished by its vegetation than those of inferior 

 elevation, situated on the banks of the Tscharysch and Koksun, 

 being extremely arid, though sparingly producing, here and 

 there, individual groupes of plants, and exhibiting such only 

 as are entirely peculiar to itself Two species of Anabasis, 

 a new and shrub-like Atriplex, likewise an undescribed 

 frutescent Chenopodium, and three new Zygophylla, a couple 

 of novel, shrub-like, and very strongly scented Artemisice; 

 Corydalis stricta in large bushes ; some species of Oxytropis, 

 with persistent prickly peduncles, some with verticillate 

 leaflets, forming low shrubs ; these, together with a few other 

 plants, form the whole of the certainly poor, but highly
