Plate XIV. 



Fig. 1 . An ovary of Ceratophyllum demermm ; and 2. the anterior surface 

 of the stigma. 



Fig. 3. The ovary of Piperomia magnoliafolia ; and 4. the axis divided 

 perpendiculai-ly, an ovary and its bract being left attached. 



Fig. 5. A perpendicular section of the ovary of Chloranthus inconspicuus. 



Figs. 6 & 7- The ovary of Sassafras officinale ; and 8. a section of the 

 same, showing the placentation and the position of the raphe, 

 which is to some extent artificially separated. 



Fig. 9. The fruit of a Stilbe (S. virgatal); and 10. a transverse section 

 of it. 



Fig. 12. An ovaiy of Mirahilis jalapa before the flower expands ; 1 1 . the 

 same at an earlier stage ; and 13. the same after the flower has 

 expanded, showing the ventral sutiu-e. 



Fig. 14. A flower of Pimelea decussata, a portion of the tube of the calyx 

 and wall of the ovary having been removed so as to show the pla- 

 centation : — a, the anterior side. 



Fig. 15. A perpendicular section of the ovary and ovule ofAucuba japonica. 



Fig. 16. An ovary of Pedicularis palustris. 



Fig. 17- A flower oi Mendozia puberula, a portion of the corolla and wall 

 of the ovary having been removed to show the position of the 

 fertile cell : — a, its lower lip ; 18. a fruit of the same ; 19. a sec- 

 tion of it showing an immatiu-e seed in the upper cell, and the 

 remains of the barren cell behind it ; 20. a section of a fruit of 

 M. puberula (var.) ; and 21. a flower of 31. aspera : — a, the lower 

 lip of the corolla (ascertained to be so by the position of the didy- 

 namous stamens). 



Plate XV. 



Fig. 1. The anterior aspect of the ovary of Lippia dulcis ; and 2. a trans- 

 verse section of it near the base :— a, its anterior side. 



Fig. 3. The anterior aspect of the ovary of Lantana crocea j 4. a transverse 

 section of it near the middle : — a, its anterior side ; and 5. a 

 transverse section near the base : — a, the anterior side. 



Fig. 6. An ovary of Dipsacus sylvestris in longitudinal section crowned by 

 the calyx and surrounded by the involucel. The bract (of which 

 there is one to each flower in front) is depressed, but is always 

 quite distinct from the involucel, not forming a part of it. Stigmas 

 rarely two, but often a rudiment of a second as represented by a. 



Fig. 7- A transverse section of a fruit of Sclerantkus annuus, showing the 

 cotj'ledons to be next the funiculus, but this figure is otherwise 

 partially incorrect, being rather a diagram. 



Fig. 8. A section of a seed of Gomphrena globosa, showing the relation of 

 the radicle to the funiculus. 



Fig. 9. Atriplex laciniata ; part of the perigone having been removed and 

 the embryo exposed. 



Fig. 10. A perpendicular section of a 2-celled ovary of Circcea a^nna ; and 

 11. a transverse section of a 1 -celled ovary of the same. 



Fig. 12. A fruit of Hippuris vulgaris (the external integument having been 

 removed), showing the shallow furrow on the posterior side of the 

 bony endocarp. 



Fig. 13. A fruit of Centaurea nigra as seen laterally — a, being the ante- 

 rior angle. 



Fig. 14. Bakia sp. j a section of the flower; and 15. a tr.insvetse section
