petiole

Stem beneath blade

A petiole is the slender stalk that attaches a leaf blade to a plant stem.

In botany, it's the leaf's support structure, conducting water and nutrients while positioning the blade for light: The petiole snapped when I tugged the leaf.

In entomology, petiole refers to the narrow waist segment connecting an ant's thorax to its abdomen.
