Leaf Morphology: Apices

the shape of the tip of the leaf furthest from the petiole

Acuminate	shaped like an acute angle with a long attenuated point
Acute	shaped like an acute angle but not attenuated
Mucronate	abruptly tipped with a bristly midrib extension (mucro)
Cuspidate	tip concavely constricted to an elongated sharp, rigid point
Obtuse	blunt, the sides forming an angle of more than 90 degrees
Rounded	a full sweeping arc
Truncate	cut off at right angles to the midrib
Retuse	with a shallow, narrow notch
Emarginate	with a shallow, broad notch
