Auriculate Leaf Base

Ear-lobe shaped leaf base(s) attached to petiole.

The English Oak is an outstanding example of this characteristic and is used to easily distinguish it from other oaks such as a White Oak.

The leaf base on the Bigleaf Magnolia displays characteristics somewhere in between auriculate and subcordate.
