Pistacia atlantica

Pistacia atlantica is a species of pistachio tree known by the English common name Kurdish bīnka/banê, Mt.

The leaves and branches often have galls when the tree is infested with gall-producing species of aphids, including Pemphigus utricularis,[6] Slavum wertheimae, and Forda riccobonii.

[8] The oblong, fleshy, oily fruit borne by the female tree is 6 to 8 mm (0.24 to 0.31 in) long and pink in color, ripening to blue.

The leaves are oval, almost sessile, shining above, and dark green, with seven to 9 leaflets, imparipinnate with petioles a little winged, flowers in racemes lax, the male and female on different trees.

[citation needed] The flowers are unisexual, small, discreet green, thick as pea fruit, then changing to reddish blue.

[citation needed] It is native to a section of Eurasia from North Africa to the Iranian Plateau, where it was once common.

[6] Because other trees were rare, it was the only good source of wood and was overharvested, reducing its current distribution.

[6] It is a common tree in mountain forests in Iran,[6] and it is "characteristic" of the landscape in parts of Algeria outside the Sahara.

[10] The almacigo is a tree that extends from the North Africa and found in thermophilous forests, up to 600 m altitude.

The leaves are rich in tannins, up to 20% in the galls caused by an aphid parasite, used as the raw material for tanning in the leather industry.

The plant contains a resin, used as chewing gum in Kevan, Turkey, where it is called kevove rubber tree.

[10] Pistacia atlantica is planted as an ornamental shadebearing and drought-tolerant landscape tree in gardens and parks.

[16] Both introductions have led to its escape and current status as an occasional invasive species in California.
