16. Outer view of placenta removed from the ovaria, representing the situation of the ovula of 



one cell. 



17. Lateral view of three ovula of one side of the cell of the ovarium, removed with portion of 



the placenta. 



18. One of the middle ovula viewed on its inner face. 



19. Do. the second integument, enclosing the nucleus. 



20. One of the lowermost and perfect ovula, inner face. 



21. Do. viewed laterally. 



22. Do. upper part of outer integument cut away, exposing the upper part of the second coat, 



within which is seen the apex of the nucleus. 



23. Mature fruit, several times enlarged. 



24. Transverse section of a capsule. 



25. Longitudinal do. running through both cells, and exposing the situation of the lateral seeds 



of each, the base of the perfect ones alone visible. 



26. Fruit, riatural size ; more of the ovaria in this case are abortive than usually happens ; one of 



the capsules has fallen off. 



27. loner face of upper abortive seed. 



28. Long section of one of the middle do. shewing it to be solid. 



29. Inner face of perfect seed. 



30. Long section of do. wing removed almost entirely, apex of the second coat exposed. 



31. Embryo. 



32. Neck of the second integument, highly magnified. 

 All with the exceptions of No. 1 and 26 magnified.

2. Ditto long section through the centre. 



3. Longitudinal section of a capsule through both cells ; seeds in one cell remaining in situ, of 



the other removed. 



4. Transverse section of a capsule. 



5. Seeds of one cell removed in situ, viewed on the outer face. 



6. Capsule after dehiscence, removed. 



7. Inner view of half the preceding, separated along the septa.
