A flower is a modified condensed shoot specialized to carry out sexual reproduction in higher plants. Like a branch it arises in the axil of a small leaf-like structure called bract. the terminal parts of the axis of a flower, which supports all the floral appendages(i.e.,sepals, petals, stamens and carpals),is called receptacle. The receptacles consist of several crowded nodes which are separated by condensed internodes. The internodes of the branches that lies below the receptacle is called pedicel. A bract is usually situated at the base of pedicel. Sometimes small leaf-like structures are present in the middle of pedicel.They are called bractioles.
