THE STRUCTUEE OF FLOWERS. 



sunk within a mass of parenchymatous tissue. In fact, they 

 might often be called " falsely syncarpous," a term applied 

 to the Pomece^ but which is equally applicable to Ivy and 

 Fuchsia. 



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 inins 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,
