Floral buds are collected and immediately fixed in FAA and prepared for paraffin embedding. Successive cross sections 8 μm thick are made to describe the organization of the
floral parts at 8 different levels of the bud. Sections stained with safranin – alcian blue have been photographed with Color Digital Camera Leica DC 300F mounted on a microscope Leica DMI RE2. Below microphotographs of a few of the sections for which description is given.
