several Alyssa, Chorispora stricta, Goldbackia, many Lepidia, 

 MegacarpcEa laciniata, Sterigma tomentosum, Tauscheria; a 

 host of Astragali, several of them frutescent, Hedysarwn splen- 

 dens, Mobifiia Halodendron, Cirsium igniariwn, and a variety of 

 Saussurece, Serratulm and ScorzonercB, with Tragopogon ruber, 

 and many others. Nevertheless, many of these plants occur 

 also even in the territory of Loktewsk. If you ascend from 

 these steppes to the mountain, the vegetation assumes, when 

 at an elevation of 4,500 Parisian feet, a greater similarity to 

 that of Europe than it presents in the steppe itself; although 

 many of the peculiar productions of this country may be seen 

 here too. The latter principally belong to the vernal plants ; 

 they also grow on the steep sides of the rocks, or adorn the 

 banks of the wild mountain- streams, wherever these are 

 subject to occasional inundations. It is in such spots that 

 Gentiana acaulis and Cortusa Matthioli flourish, where Car- 

 damine ma^rophylla, Saxifraga Geum,* Pedicularis resupinata 

 and others, grow in the greatest luxuriance. Also, rich flat 

 meadows, situated at the foot of the higher mountains, or 

 stretching between them, produce many of the peculiar plants 

 of Siberia; while, on the contrary, gently rising hills, or 

 spots clothed with scattered woods, exhibit such vegetation 

 onJy as is common to Europe. This is likewise observable 

 in such places as form standing bogs, and are neither 

 irrigated by the fresh water trickling down the mountains, 

 nor shaded by a thick covering of foliage. Still the morasses 

 of this region do possess some plants peculiar to themselves. 

 The Spring Flora is peculiarly marked by the abundance 

 of its RanuncidacecE and Liliacea;, Ranuncidus polyrhizos, 

 Adonis vernalis, sibirica, and villosa, Pceonia hybrida, Anemone 

 patens, ccerulea^ altaica, and unibrosa (n. sp.), Atragene alpina, 

 Ornithogalum angulosum (n. sp.), and uniflorum, Tulipa altaica 

 and tricolor. Iris ruthenica, glaucescens (n. sp.), and Jlavissima. 

 Among the rock-plants of this region, may particularly be 

 noticed the following, as being most numerous, although 

 some are not generally diffused, but abound in individual 

 tracts — (the latter are indicated by *.) Veronica pinnata, 

 Ziziphora media, Dracocephalum origanoides* , peregrinum,
