pinnate
Like oak leaves
Pinnate describes a feather-like arrangement, with parts extending from opposite sides of a central axis.
Pinnate leaves have leaflets arranged along a stem like barbs on a feather: The walnut tree has pinnate leaves.
The term appears in botany and zoology for any structure showing this bilateral, feathered pattern.
