Leaf Margin: Spinose

Spinose Leaf Margin

Definition: Bearing spines along leaf margins, or tiny spines at nodes on stems.

Description: Often these spines occur on the margin where the leaf veins terminate at serrations at the leaf margin.

In the case of the Holly (Ilex) shown here, the leaf would be further described as involute (curling upward ).
