Linear: These are long and narrow with parallel edges, much like a blade of grass.
-
Lanceolate: These leaves are wider in the middle and taper towards the end, resembling a lance tip.
-
Elliptical: These leaves are oval-shaped, being wider in the middle and narrow at the ends.

Oblong: These leaves are almost rectangular, with parallel sides and rounded or slightly tapered ends.
