leaves may also be formed of lobes where the gaps between lobes do not reach to the main vein.
simple leaf
forming leaflets that are attached to the middle vein but have their own stalks.
compound leaf
The leaflets of _____________ leaves radiate
outwards from the end of the petiole.
palmately-compound
They have their leaflets arranged along the middle vein
Pinnately-compound
leaves have their leaflets arranged along a secondary vein,
which is one of several veins branching off the middle vein.
Bipinnately-compound (double-compound)
also known as double-compound
Bipinnately-compound
a leaf with an undivided blade
simple leaf
a leaf where the blade is divided, forming leaflets.
compound leaf
leaf that has its leaflets radiating outwards from the end of the petiole.
Palmately compound leaf
a leaf where the leaflets are arranged along the middle vein.
Pinnately compound leaf
The two basic forms of leaves that can be
described considering the way the blade (or lamina)
is divided.

scrub hickory (Carya floridana)
