A small notch, indentation, or scalloped edge, particularly in botanical or biological descriptions.
From Latin cremula, diminutive of crena (notch or indentation). The -ule suffix indicates something small, so cremule literally means 'a small notch,' used in scientific descriptions.
Cremule is such a specific scientific term that it helps researchers describe tiny structural details—the difference between 'wavy' and 'having cremules' is the precision botanists need when distinguishing similar species!
