What distinct visual feature identifies the kaffir lime leaf structure?

Answer

Double-leaf shape resembling two leaves joined at the base

Kaffir lime leaves possess a very unique and easily identifiable physical characteristic: their double-leaf shape. This morphology resembles two separate leaves that are fused or joined together at the base, setting them apart visually from the common Persian or Key lime leaves. Although sometimes a single-lobed version might appear, the defining feature used for identification is this distinctive, paired structure.
