Leaf Margins: Spinose
Has spines along leaf margins or has tiny spines at nodes on stems. 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 (upward curling).
