Male flowers from Caucasian wingnut

 

Pterocarya fraxinifolia – Caucasian wingnut.

The picture shows the characteristic long, hanging male flowers.

 

Pterocarya fraxinifolia is a deciduous tree in the walnut family (Juglandaceae), typically with long, hanging seed catkins (30–50 cm) that carry green, winged nuts – a clear recognition feature.

The tree has large, imparipinnate leaves up to about 60 cm long with 7–27 leaflets and decorative and broad-crowned growth form, often with multiple stems and a short, thick trunk.

 

The tree is native to the Caucasus region and northern Iran, but often planted in parks and large gardens across Europe because of its ornamental value and ability to thrive in damp areas.
