Platanus orientalis

The oriental plane is in the plane tree or Plantanaceae family and has a native range in Eurasia from the Balkans to at least as far east as Iran. It grows to over 30 m tall and is known for its longevity and spreading crown.

• Leaves are simple, alternate, deeply lobed (distinct from more shallowly lobed P. occidentalis), and palmately veined. In summer, buds are completely hidden by the bases of the petioles.
• Species is monoecious. Flowers appear in May along with the leaves, in dense heads. Female (staminate) and male (pistillate) heads are on separate stems (peduncles). The staminate heads are dark red, on auxiliary peduncles; pistillate heads are light green tinged with red, on longer terminal peduncles.
• Fruit forms seed balls (achenes) 2.5 cm in diameter, normally 2–6 per stock (distinct from normally 1 or 2 in P. occidentalis), which hang on stems 7 to 14 cm long, remaining on the tree over the winter.
• Twigs are zigzag; leaf scars completely surround the twig; buds are conical.
• Bark is exfoliating, although on old trees, it becomes thick and rugged.
