EXPLANATION OF PLATES LXXLLXXIIL 



Plate Ixxi. 



Fi^. L — 1'ransveise section of stalk at base f)f fruit, showing the ten dis- 

 tinct fibre- vascular bundles ( x 30). 



Fig.2. — Transverse median seotion, showing the five carpels and the 

 "stone cells." In the mature quince, the position of the primary' 

 vascular bundles is obscured by the " stone-cells." 



Fig.3. — Longitudinal median seotion, showing the "core" towards the 

 blossom-end. The primary vascular bundles are seen traversing the 

 flesh from the stalk-end towards the carpels, which are surrounded 

 by a dense layer of stone-cells. The stone-cells are also scattered 

 through the flesh, and there are thin streaks here and there, in- 

 dicating the vascular bundles. 



Plate Ixxii. 



Fig. 4.^ — Longitudinal median section of youn^' pear-shapetl quince, siiowing 

 the " core " occupying the greater portion of it, and tiers of seeds in 

 the carpels. There is a cavity between the carpels, tapering 

 towards the styles ( x 3). 



Fig.5. — Transverse median section of young quince, showing the ten 

 vascular bundles surrounding the core, which occupies tlie greater 

 portion of the section, and the cavity is shown in tlie centre ( x 3). 



Fig.6. — Longitudinal median section of young apple, showing "core" and 

 flesh distinct ( x 3). 



Fig.7a,6. — 'iVansverse median sections of very young apples, showing dis- 

 tinct " core," and ten fibro-vascular bundles surrounding it( x 3). 



Fig. 8. — Longitudinal section of young pear, showing the elongated fleshj' 

 portion below the seed-vessels.. 



Fig. 9. — Tiaiisverse section of young pear, showing the fil)ro- vascular 

 bundles surrounding the core, five being at the outer tips of the 

 seed-vessels, and five intermediate. The stone-cells are scatteied 

 all through the flesh. 



Plate Ixxiii. 



Fig. 10. — Young apple-fruit (Cleopatra), just after the petals have fallen, 

 showing the very delicate vascular network beneath the skin, even 

 at tliis early stage ( x 3).
