TERMS RELATING TO LEAVES
LEAF ARRANGEMENT
ON A TWIG OR STEM:
LEAF VENATION
(VEIN PATTERNS)
NUMBER OF BLADES
The purpose of a leaf is to collect sunlight, so the ability to spread out and ‘catch’ as much sunlight as possible is important for trees in a forest. To maximize their ability to spread without having to create more leaves, some trees produce leaves that have many small blades rather than one large one. Leaves with more than one blade are called compound leaves.

LEAF MARGINS
The margin is the edge of the blade, and the following terms apply to both simple and compound leaves. There are more than 100 terms used to describe leaf margins, but those shown below are the most common and most relevant for trees in our area:
LEAF SCARS
In the fall, deciduous trees drop their leaves and go dormant. Buds remain on the twigs, and ‘leaf scars’ can be seen where each leaf had been attached. Leaf scar size and shape varies considerably between species. Within each leaf scar, ‘bundle scars’ or ‘vein scars’ show where the leaf’s veins once connected to the stem. The pattern formed by bundle scars also aids in identification.

Lobed
Note that the lobes follow the
leaf’s venation pattern, and may be either pointed or rounded.
