There are so many particular forms of flowers that it would be impossible to notice or describe them all in this place. In some cases the flower is a little stem (axis) upon which are pollen-bearing or ovule-bearing leaves (stamens or ovaries); these clusters of reproductive organs may have a number of sterile leaves below them on the stem, the floral leaves, or perianth. In other cases both kinds of re-.
