Lilium, Euphrasia, Equisetum, Rosa, Salsola, Allium, Galium, 

 Sanguisorha, Artemesia (with parasitic Orohanche), Geranium, 

 Spiraea, Cotoneaster, Fragaria (wild strawberries are abundant 

 and much used for preserves), Linaria, Aconitum, Convolvulus, 

 Scutellaria, Agrimonia, Sedum, Campanula, Thymus, Potentilla, 

 Sisymbrium, Epilobium, Plantago, Achillea. This is a very 

 typical Palaearctic series, with no infusion of oriental elements. 

 Returning from Ust Balei, we visited the Biological Station of 

 the University of Irkutsk, on the western shore of Lake Baikal. 

 This is a charming spot, with flowery meadows and pine-covered 

 hills, and in front the great lake, with the Transbaikal Moun- 

 tains on the other side appearing high and formidable. Perhaps 

 the most conspicuous and splendid flower of this region is the 

 magnificent blue Delphinium grandiflorum. According to Hans 

 Johansen of Tomsk (1925) there is around Baikal an endemic 

 variety, turczaninowii Popl. but whether all the plants belong 

 to it I do not know. A species of Sanguisorha is extremely 

 abundant throughout this country: Johansen cites a species S. 

 baicalensis Popl. peculiar to the region, but the local botanists 

 refer the common plant to the European species. The birch is 

 considered to be Betula alba verrucosa; Johansen mentions a B. 

 baicalensis from the vicinity of the lake. We found the yellow 

 poppy which Johansen cites as a possible endemic variety of 

 Papaver nudicale. Other local forms or species are referred to 

 under Polygonum, Elymus and Festuca, but I gather that on the 

 whole the flora is not at all rich in peculiar species. It impresses 

 one as essentially of European type, with little in common, so 

 far as species are concerned, with the flora of the Maritime 

 Province, which we saw in 1923. Thus we saw no sign of the 

 Trollius ledebouri and the flame-colored Lychnis fulgens so con- 

 spicuous in the Maritime (Primarsky) Province. On the other 

 hand, one has the feeling that several of the species, assigned 

 to European types, are not exactly the same and might be 

 considered racially distinct. The Achillea millefolium is nearly 

 all various shades of pink; the Chrysanthemum leucanthemum is 

 variable and perhaps not quite the same as the plant familiar 

 in England. Another Chrysanthemum, with pinkish flowers, is 

 C. sibiricum. Chelidonium majus appears to be exactly as in 

 Europe; so also Rhinanthus crista-galli. Geranium is represented 

 by two splendid large-flowered species, G. eriostemon and G.
