Having two ear-shaped lobes or projections; possessing two auricles or ear-like structures.
From Latin 'bi-' (two) plus 'auricula' (small ear or ear-like structure) plus '-ate' (having). This botanical and zoological term describes structures with two ear-shaped parts.
Some plants have biauriculate leaves—leaves with two little ear-like flaps at the base—and botanists use this specific word so precisely that they can identify plant species just by the leaf shape!
