Having two crenations or rounded scalloped notches; describing a margin with two sets of small rounded projections.
From 'bi-' (two) + 'crenate' (having rounded notches), from Latin 'crenatus.' Used in botany to describe leaf margins with a specific double-scalloped pattern.
Some plant leaves have bicrenate edges—like a scallop shell pattern repeated twice—and botanists use these microscopic edge details like fingerprints to identify and classify plants, which is why a magnifying glass and vocabulary like 'bicrenate' matter in the field.
