Tibet : between 90° and 96° long., and 35° and 36° lat., at 14,G00 

 to 16,800 feet, Wellby & Malcolm. 



Saussurea Wellbyi, Hemsl., is one of a small but exceedingly inter- 

 esting collection of plants made by Captain Wellby and Lieutenant 

 Malcolm on their memorable journey across Tibet, from west to east. 

 Considering the hardships and privations they underwent, it is sur- 

 prising they were able to bring away anything. Kew previously 

 possessed no specimen of this species, nor have I been able to identify 

 it from descriptions of species not represented in the Herbarium. A 

 note accompanying the specimens runs as follows : ' Found widely 

 distributed in flower during August and September.' — W. Bottixg 

 Hemsley.
