Leaf apex

The shape of the tip (apex) of the leaf. The description of leaf apex shape is generalised and subjective. Leaves on a plant can vary in shape and size and between individuals. Users should take a relatively broad interpretation of the leaf apex shape.

Rounded: the leaf apex is broadly rounded or blunt (obtuse).

Acute: the leaf apex ends in a short sharp point.

Acuminate: the leaf apex ends in a long drawn out point.

Apiculate/mucronate: the leaf apex ends in a short protruding point.

Hooked: with the apex distinctly hooked to one side (uncinate).

Notched/unequally emarginate: with the apex distinctly indented (emarginate) or one side of the leaf apex extends further than the other.
