Bracts.—In examining flower arrangements, the flowers are usually found protected by one or more leaf-like bodies, green or coloured, which may have been mistaken for the calyx. In Gla- diolus, AnfJiolyza, and their relatives, this mis- take is often made, but you will find that in these flowers the sepals are like petals, and are borne at the top of the ovary. Leaves in whose axils flower-buds instead of leaf-buds arise, are termed bracts. They are gener- ally smaller than leaves, but sometimes much larger and more showy than the flowers, as in Protea, Poinsettia, and HcEmanthus. When several bracts surround a head of flowers, as in Protea, the Barberton Daisy, and others of their tribe, they form an involucre. When a bract is large and sheaths the inflorescence, as in Arum, it is called a spathe. Bracts which enclose the flowers of grasses and sedges are called pales and glumes,.
