ANACARDIACEAE. — PISTACIA 173 



otherwise the Chinese tree will have to be referred to another species, although 

 the herbarium material before us from the two countries is identical. 



The fruit of S. axillaris is yellow, oval, from 2.5-3 cm. long, rounded on the 

 summit; it is eaten by the Chinese. The vernacular name of this tree is " Hsuan 

 Tsao." 



Pictures of this tree will be found under Nos. 377 and 441 of the collection of 

 Wilson's photographs and also in his Vegetation of Western China, Nos. 477 and 

 478. 



Spondias axillaris, var. pubinervis Rehder & Wilson, n. var.

 et rhachi et ramulis junioribus dense breviter villosis. 



Eastern Szech'uan: Taning Hsien, roadside, alt. 160-100 m., 

 June 28, 1910 (No. 4631, type; tree 20-25 m. tall, girth 3 m.); Wushan 

 Hsien, A. Henry (No. 5535). Western Szech'uan: Hungya 

 Hsien, roadside, alt. 600 m., September 5, 1908 (No. 480'*; tree 6-25 

 m. tall, fruit yellow, edible); Yachou Fu, ravines, alt. 600-1200 m., 

 May and July 1904 (Veitch Exped. Nos. 3368, 3373, 3363). 



This variety is well distinguished by its pubescence; in other particulars it is 

 identical with the type of the species. This tree is common everywhere in Sze- 

 ch'uan up to 1000 m. altitude. 



Pictures of this tree will be found under Nos. 94 and 0161 of the collection of 

 Wilson's photographs and also in his Vegetation of Western China, No. 476.
