The leaves are bigger, tougher, and the appendages on either side of the stalk (which botanists call the stipules) more developed.
Most Willows show the stipules on the young luxuriant growths.
The stipules at the base of the long foot-stalk are small or altogether wanting.
Even if the stipules have dropped off, the small scars remain.
Its stipules are large, narrow-oval in form, with an arrow-shaped base.
The presence and character of the stipules should always be noted.
The stipules are always free from the leafstalk and attached to the twig at small spots just below the leafstalk.
The leaves are simple, cordate, opposite to each other, and furnished with stipules.
The leaves are pinnate, consisting generally of nine leaflets, and each pair of leaflets is furnished with two stipules.
I may here be asked what are stipules, and in what do they differ from leaves?
"small appendage at the base of the petiole of a leaf," 1793, from French stipule, from Latin stipula "stalk (of hay), straw."
