leaf scar

noun

, Botany.

leaf scar

The mark left on a stem after a leaf falls. Leaf scars can be used to identify tree species in winter or from specimens of their twigs.

A lateral bud is one situated on the side of a twig in the axil of a leaf-scar.

The leaves are trimmed off, from season to season, leaving the bare stalk, showing the leaf-scar.

The scales, being stipules, leave a line on each side of the leaf-scar, and these are separated by the growth of the internodes.

The flower-clusters do not seem to leave any mark which is distinguishable from the leaf-scar.

The dots on the leaf-scar are the ends of woody bundles (fibro-vascular bundles) which, in autumn, separated from the leaf.
