Lanceolate

Lanceolate, shaped like a, little lance, a term applied to the form of leaves, in slightly differing senses by various writers. Some define it as narrowly elliptical, tapering to each end - widest, that is, across the middle. Others consider it more typically represented by a narrow leaf widest near the base and tapering upwards. Both forms occur in many willows.
