It has a long acuminate apex and both surfaces are covered in fused scales with a thin clear skin-like covering (pellicle) that peels away in strips on old leaves. 

Flower: The small pedicellate tubulate male flowers with a short tube and tepals that soon reflexed and the female flowers are smaller and erect and found on a different plant (dioecious). They are arranged in an erect at first then drooping panicle to 500mm (20in) tall that is held above the foliage on a scape during spring.
