toothed leaf-margin

A toothed leaf-margin has incisions or notches that reach less than approx. 25 % of the width of the lamina (cf. also lobed lamina). The main differentiation is between a crenate leaf-margin (with obtuse or rounded teeth, e. g. in Glechoma hederacea – Ground-ivy) and a dentate leaf-margin (with acute teeth, e. g. in Carpinus – Hornbeam).
