PISTACIA CHINENSIS. CHINESE PISTACHE. 
Photograph of a tree eighty feet in height and ten feet in 
circumference, taken August 2, 1908, by Mr. E. H. Wilson, col- 
lector for the Arnold Arboretum, on the slopes of Pei Yueh Ling, 
near the Tung River, at an elevation of 6500 feet. This hardy 
pistache, first introduced as a horticultural possibility by Mr. 
Frank H. Meyer, agricultural explorer, from northern China, is be- 
ing introduced in quantity as a possible stock for the true pis- 
tache nut of commerce, Pistacia vera, and also as a shade tree 
for the Southwest. Because of its greater hardiness it promises 
to extend widely the range in which the pistache can be grown.
