PLANTS FROM WESTERN CHINA. 

 By R. S. Adamson, B.A. 



The following is an account of a small collection made by Mr. 

 F. K. Ward on a recent expedition in China in 1909-10. The 

 plants were collected in the mountainous regions round Tatsienlu, 

 in W. Szechwan, and in S. Kansu Mts. The collection was sent to 

 Professor Seward at Cambridge, who kindly handed the plants 

 over to me for investigation. The specimens are in the Cambridge 

 University Herbarium. I have to acknowledge considerable help 

 from Dr. C. E. Moss, of the Cambridge University Herbarium, 

 and also from Dr. 0. Stapf and other members of the staff of the 

 Kew Herbarium during the process of identification of the speci- 

 mens, many of which were unfortunately very small. 



The collection contains five new species, three of which are 

 now described ; the others will be described by Mr. R. A. Rolfe. 



The nomenclature is in most cases that adopted in Mr. 

 Hemsley's Enumeration of Chinese Plants.
