Observations on the Vegetation of the Siberian-Mongolian 



Frontier, the North-West Mongolian Plateau, 



AND Chinese Dzungaria. 



By M. p. price. 



The expedition which yielded the material for the present paper was under- 

 taken during the spring and summer of: 1910 in company with Mr. Douglas 

 Carruthers and Mr. J. H. Miller, the former of whom contributed a paper 

 on the geographical results of the expedition to the Royal Geographical 

 Society's Journal in June 1912. 



Botanical observations and collections were made by the writer of this 

 section of the paper throughout the journey from Minnusinsk to the Siberian- 

 Mongolian frontier and through N.W. Mongolia and Chinese Dzungaria 

 until Kuldja was reached. A map showing the route of the expedition 

 and the localities mentioned in the paper will be found on PL 20. It has 

 been reprinted, with the addition of certain place-names, from the Journal 

 of the Geographical Society, June 1912, with the permission of the Society. 

 The plants collected by me have been worked out by Mr. N. D. Simpson, 

 who has incorporated most of my field-notes in the part of the paper under 

 his name. My thanks are due to the Royal Geographical Society for per- 

 mission to reproduce the map, and to the Director of the Royal Gardens, 

 Kew, for permitting Mr. Simpson to use the material in the Kew Herbarium.

 Itinerary and General Notes. 



The Upper Yenisei plateau comprises an area drained by two rivers, called 

 by the natives the Bei Kem and the Khua Kem, and is the upland from 

 which the Siberian Yenisei River rises on the border of Siberia and 

 Mongolia. The area is roughly 64,000 square miles, and the whole 

 drainage area unites in one large stream called the Ulu Kem, and bursts 

 throuc'h the mountain wall of the Sayansk range about 150 miles south of
