lobed leaf
Definition
Noun: A leaf characterized by having deep indentations or divisions along its margin, creating distinct, rounded projections or segments called lobes. The indentations do not reach the center or the midrib of the leaf.
Usage
The term "lobed leaf" is used in botany and plant identification to describe the specific shape of a leaf blade. It classifies leaves based on the depth and pattern of the marginal incisions.
