Leaf Margin: Lobulate

Lobulate Leaf Margin

Definition: Small curved sections, smaller than lobed, along the leaf margins.

Description: Small lobes around leaf edges, smaller than lobed Lobed leaves (or petals, etc.) are divided to about the mid-point between the midrib and the margin. Lobulate leaves have less deeply divided sections, and are further described using another characteristic i.e. a serrated lobulate margin.
