This important tree is cultivated in vast numbers in western Hupch and Sze- 

 ch'uan, especially in rocky places, from river level to 1000 m. altitude. An ac- 

 count of this tree and of the methods of expressing the oil from the seeds will be 

 found in my A Naturalist in Western China, II. 65 (1913). 



Pictures of this tree are to be found under Nos. 31, 37, 38, 44, 45, 460, 0171, 

 0350 of the collection of my photographs and also in my Vegetation of Western
