EXPLANATION OF FIGURES IN PLATES 
XXV AND XXVI. 
Illustrating Mr. Farmer’s paper on the Morphology and Physiology of Pulpy Fruits. 
Figs. 1-14. Hedera Helix. 
Fig. 1. Longitudinal section through young bud. The shaded part represents the 
tissue of the carpel, v, vascular bundle. 
Fig. 2. Longitudinal section through elongating portion of pith, just below 
carpels, shows two cell rows pushed apart by intruding filament, F. 
Fig. 3. Longitudinal section of part of the rind : two cell rows growing past 
each other. 
Figs. 4, 5. Successive sections (transverse) through young fruit rind, aa , sections 
through the same intruding filament. 
Figs. 6, 7. Longitudinal section through rind. E , epidermis. 
Fig. 8. Transverse section through carpellary portion of half-ripe fruit, m, inter- 
cellular mucilage. 
Figs. 9, 10, 11. Transverse sections through parts of older fruits (Haematoxylin). 
Figs. 12, 13, 14. Cells with oil contents from almost ripe fruits. 
Figs. 15-18. Crataegus Oxyacantha. Middle lamella, coloured yellow. 
Fig. 15. Transverse section of ^-ripe mesocarp. The well-differentiated middle 
lamella as seen when mounted in water. 
Fig. 16. The same in potash. 
Figs. 17, 18. Somewhat older, mounted in Schultz solution. 
Figs. 19-23. Rubus fruticosus. 
Fig. 19. Diagrammatic transverse section, young fruit, showing layers of the 
endocarp. 
Fig. 20. Same in longitudinal section. 
Fig. 21. Transverse section of ovary in the bud. 
Fig. 22. Same sometime after flowering. 
Fig. 23. Same when almost ripe. 
Figs. 24-32. Solanum Dulcamara. 
Fig. 24. Longitudinal section, ovary in flower. 
Fig. 25. Same shortly after flower has withered. 
Fig. 26. Transverse section of ovary in same style as in Fig. 25. 
Fig. 27. Transverse section, young epicarp. 
Fig. 28. The same much more advanced, part of the mesocarp also shown. 
E = epidermis. 
Fig. 29. Transverse section of inner portion of pericarp in same stage as Fig. 25 ; 
some of the cells are dividing tangentially, to form the inner ovular protuberances. 
I. E. inner epidermis or limiting layer. 
Fig- 30. Shows the pericarp (Pe), meeting placental (PI) outgrowth, round two 
ovules ( 0 ). 
Fig. 31. Transverse section through ovule, showing mucilaginous layer ( m ). 
Fig. 32. Mucilaginous layer (m) in later stage ; s, the thickening seed-coat.
