This Pistacia is one of the noblest, most widely distributed and useful of Chinese 

 trees. It is very common in the valleys of western Hupeh and Szech'uan up to 

 1000 m. alt. and extends up to 1600 m. alt. in favorable localities. The trunk is 

 very thick, buttressed at the base with gray, fissured persistent bark; the branches 

 are massive, wide-spreading and form a rounded or flattened head. The young 

 leafy shoots are often red in color and are eaten as a vegetable in the same manner as 

 those of Cedrela sinensis A. L. de Jussieu. In the autumn the leaves assume wonder- 

 ful orange and crimson tints. The wood is heavy, close-grained, tough but easily 

 worked and is employed in boat-building, for general construction purposes and 

 in household carpentry. Stout poles of this tree having a natural fork are consid- 

 ered to make the best and most durable rudder-posts for large boats. 



Colloquially this tree is known as the " Huang-lien shu " or " Huang-ni-ya 

 shu." 



Pictures of this tree wiU be found under Nos. 14, 25, 262, 443 and 0225 of the 

 collection of Wilson's photographs and also in his Vegetation of Western China, 

 Nos. 384r-387. 



Hayata's excellent figure shows that Matsumura's P. formosana is identical 

 with the Chinese species and we can find no character by which to distinguish P. 

 philippinensis Merrill & Rolfe. In this connection we may observe that Mer- 

 rill and Merritt suspected the identity of the Philippine species with that of 

 Formosa. 



Pistacia integerrima Stewart (in Brandis, For. Fl. Brit. Ind. 122, t. 22 (1874)) is 

 very closely related to P. chinensis and perhaps, is not specifically distinct., 



Here may be added a note on a species not collected during the Arnold Arbore- 

 tum Expeditions.
