Spathe
A spathe is a large bract or a pair of bracts that forms a sheath to enclose the flower cluster of plants such as palms, arums, irises, crocuses and dayflowers (Commelina). Zephyranthes tubispatha in the Amaryllidaceae derives its specific name from its tubular spathe. In many arums (family Araceae), the spathe is petal-like, attracting pollinators to the flowers arranged on a type of spike called a spadix.
