are usually borne in clusters on special branch systems 
which are termed INFLORESCENCES. Lach floral axis

arises in the axil of a leaf which in this case is called a 
Bractr. Leaves borne on the floral axis itself are called 
BRACTEOLES. When several bracts surround a single 
flower, eg. Pink, or an inflorescence, e.g. Sunflower, 
they form an InvonucRE. When a single bract is en- 
larged and ensheathes a single flower, e.g. Narcissus, 
or an inflorescence, e.g. Arum, it is called a Spatuz. If 
bracts are present the flower is said to be BRacTEATE, 
if absent, EBRACTEATE. If the main vegetative axis of
