CRE'NATE, or CRE'NA-TED, a. [L. crena, a notch, whence crenatus, notched. See Cranny.]

Notched; indented; scolloped. In botany, a crenate leaf has its edge, as it were, cut with circular incisures, not inclining toward either extremity. When the scallops are segments of small circles, it is said to be obtusely crenated; when the larger segments have smaller ones upon them, a leaf is said to be doubly crenate. – Martyn.
