998 MR. M. P. PRICE ON THE VEGETATION OF 
Atraphawis lanceolata, Echinops Ritro, Potentilla Anserina, Leonurus lanatus. 
The following new types were seen for the first time in their apparently 
most northerly limit :—Setaria viridis, Cannabis sativa, Halimodendron 
argenteum, Haloxylon Ammodendron, and Astragalus Pallasii. 
Proceeding southwards, the hills, which lay between 1700 and 2300 feet, 
were replaced by a plain, which lay between 1500 and 1700 feet. The plain 
was largely alluvial, with some patches of blown sand near the Black irtish 
River. As the river meandered north-westwards it was covered with breaks 
of Poplar and Willow. On the alluvial desert there appeared //alimodendron 
argenteum, Sophora alopecuroides, Glycyrrhiza uralensis, Eurotia ceratoides, 
var., Artemisia Lercheana, Elymus giganteus, and Tamarix sp. Leaving this 
low-lying plain and proceeding southwards the altitude rose to a plateau, 
which lay to the north-east of the Sair mountains. This range, which runs 
roughly east and west, joins on to the offshoots of the Tarbagatai and 
Barlik mountains and forms part of the disjointed range which runs across 
Dzungaria from south-west to north-east. The plateau to the south of the 
Sair mountains, which was drained by the Kobuk River, lay between 2000 
and 5000 feet. On it were found .Глетопе Bungeana (the same as in North- 
West Mongolia), Anemone patens, Iris ensata, Artemisia Lercheana, and 
Spired hypericifolia. On rising to 5500 feet on a pass connecting a southern 
offshoot of the Sair mountains with a northern offshoot of the Barlik, small 
patches of Lari sibiriee were seen in places sheltered from the sun. With 
it were also the accompanying flora, characteristic of Southern. Siberia and 
North-West Mongolia, namely, Aconitum sp., Potentilla bifurca var. canescens, 
Rosa spinosissima, Anemone Bungeana, and Juniperus pseudo-sabina. 
Descending to the plain of the River Emil, which flows westwards into 
Lake Ala Kul, the altitude was found to lie between 1600 and 2500 feet and 
largely consisted of alluvium. In the highest and driest parts of the plain 
Artemisia Lercheana, Stipa capillata, and Anemone patens were predominant ; 
while in the lower parts nearer the water-table the following species 
predominated : Glycyrrhiza uralensis and Elymus dasystachys. 
South of the plain of the Emil and on the northern slopes of the Barlik 
mountains were found the most northerly specimens of Picea Schrenkiana, 
accompanied by an association partly characteristic of the Larch forest of 
North-West Mongolia, but containing also many new species. Unfortunately 
the expedition reached this point too late in the year to obtain representative 
specimens of the flora, for the snow had already begun to cover the altitudes 
which lay between 5000 and 6000 feet. It was observed, however, that the 
most southerly limit of Larie sibirica was on the southern slopes of the Sair 
mountains, while the most northerly limit of Picea Schrenkiana lay on the 
northern side of the Barlik mountains. Crossing the Ala Tau mountains on 
the way to Kuldja and the Ili, large forests of Picea Sehrenkiana were 
observed rising to an altitude of over 9000 feet, but the snow was too deep 
to enable any investigation of the ground flora to be made.
