In the pedicel of a flower of Ivy, there are, at a distance of about three-quarters of an inch from the tapering base of the inferior ovary, four fibro-vascular cords (Fig. 14, a). A little higher these split up into an irregular circle (6), and shortly above the base of the receptaculartube there are fifteen (c), ten being more towards the circumference than the other five. The outer ten are for the sepals and petals. The five inner will appear superposed to the sepals (d), having been already separated off by radial chorisis rather low down; these are for the stamens. Then from the petal- ine cords, by a similar method of chorisis, a small cord runs up the dorsal part of the ovary-cell and another up the axis. This fixes the position of the five carpels (if so many be present) as superposed to the petals (d). There are often only four, or even three,.
