A small tree, from fourteen to twenty feet high, usually met with on low hills 
of limestone formation; occasionally in small groups, but never so numerously to- 
gether as to constitute a forest. Camels and goats browse on it. The nuts, though 
small, are roasted, and the kernels eaten ; but usually the kernels are crushed, and from 
them an oil obtained, which is eaten with food. The leaves are said to be employed in 
dyeing and tanning, but not the galls. The galls are developed on the margin of the 
leaf, and are very different in form from those of Pistacia vera. 
After a careful examination of the large amount of material we had to aid us, we are 
of opinion that the several forms which have been described as species may all be 
placed as varieties of P. Terebinthus, Linn.

Badghis: 390, May 3, 4, 14, 21, 1885; Khorasan: 665, June 17, 1885. Native name 
Pista. А small indigenous tree, forming forests, at an altitude оЁ from 3000 feet and 
upwards, usually on sandstone formation. Тһе country where the forests abound is 
called Pistalik, and these forests are greatly valued for their yield of nuts (Pista), as 
well as for the galls on their leaves (Boz-ganj), both of which are articles of 
commerce, especially the former, which are largely exported to India. It yields a gum- 
resin (Shilm-i-pista), employed in household medicine; and the wood is considered the 
best fuel that the country produces. "The tree is cultivated in orchards in Persia, but 
apparently not in Afghanistan, at least not in the parts visited by me.
