leaves that are 1-2 feet in length. Leaf color varies from green to deep purple. The purple color is due to pigments in the Epidermis.

Ki is a monocot and its leaves have many parallel veins which show up best on red leaves. Many veins are concentrated in the center of the leaf. This constitutes a midrib.

The Leaves were used for many purposes. They were worn for hula and served as rain-cloaks. They were also used for thatch and occasionally for sandals. They were also involved in cooking.
