    Figure \(\PageIndex{1}\): A woody shoot and labeled scars. The most prominent scar on this shoot is the v-shaped leaf scar, which is lined with circular vascular bundle scars. Above the leaf scar, in the crotch of the v it forms, is a round axillary bud scar. Covering the bark are many small, circular scars. These are lenticels. Photo by Maria Morrow, CC BY-NC.

    Birch lenticels are elongate instead of circular
    Figure \(\PageIndex{2}\): A piece of birch bark. The lenticels in birch bark form as long tears, as opposed to the circular ones in Figure \(\PageIndex{1}\). Photo by Maria Morrow, CC BY-NC.

    Figure \(\PageIndex{3}\): Diagram of a woody shoot (angiosperm). A=Terminal (or apical) bud, B=Terminal bud scale, C=Node, D=Internode, E=Axillary bud (in the leaf axil), F=Leaf, G=Lenticel, H=Leaf scar, I=Axillary bud scar, J=Vascular bundle scar (within the leaf scar), K=Terminal bud scale scars. The region between sets of terminal bud scale scars on a branch represents one year of growth. Diagram by Nikki Harris, CC BY-NC with labels added by Maria Morrow.
