描述
The pistachio, Pistacia vera in the Anacardiaceae family, is a small tree originally from Greater Iran which now can also be found in regions of Syria, Lebanon, Turkey, Greece, Tunisia, Kyrgyzstan, Tajikistan, Turkmenistan, India, Pakistan, Egypt, Italy, Uzbekistan, Afghanistan (especially in the provinces of Samangan and Badghis), and the United States, specifically in California. The tree produces an important culinary nut. Pistacia vera often is confused with other species in the genus Pistacia that are also known as pistachio. These species can be distinguished from P. vera by their geographic distributions (in the wild) and their nuts which are much smaller, have a strong flavor of turpentine, and have a shell that is not hard.
