EXPLANATION OF THE PLATES.

Fig. 8. One of the stomata of the same, more magnified, and showing that the 
medial line does not touch either end, and that the cavity of the stoma is filled 
with granular matter. 
Fig. 9. Stomata of the under side of the leaf of Caladium esculentum, with a 
portion of epidermis. These appear to be somewhat angular cellules, occupying 
the centre of every area of the epidermis. The stoma consists of an oval space, 
in the centre of which is a narrow cleft, with a border distinctly coloured 
orange or brownish, and having no communication with the circumference ; 
the space between the cleft and the latter filled with a pale green granular 
substance. The cleft is sometimes seen closed, as at a, and then there is 
scarcely any appearance of a border. 
Fig. 10. Epidermis and stomata of Yucca gloriosa ; the latter lie in square areolae, 
and consist of two parallelograms lying parallel with each other. Small sphe- 
roidal bodies, having a luminous appearance under the microscope, stick here 
and there to the inside of the epidermis. 
Fig. 11. Stomata of Limnocharis Plumieri. These also lie in square areolae, 
but they have the ordinary structure : they are found in different degrees of 
openness, or even quite closed, upon a small piece of the same specimen. 
Fig. 12. Stamen of Lemna trisulca : anther bursting vertically. 
Fig. 13. Stamen of Polygonum Convolvulus: a, seen in front ; 5, from behind ; 
c, the connectivum of the anther. 
Fig. 14. Stamen of Corrasa alba : a, seen in front ; b, from behind. 
Fig. 15. Stamen of Stachys sylvatica: a, filament ; 6, connectivum ; c, anther, 
its lobes separated at the base by the connectivum. 
Fig. 16. Anther of Alchemilla arvensis ; one-celled, and bursting transversely. 
Fig. 17. Stamen of Scrophularia chrysanthemifolia : a, part of the filament, and 
the anther, which is one-celled, after bursting ; b, the same, before the dehi- 
scence of the anther. 
Fig. 18. Anther of Lamium album; its lobes, as in fig. 16., separated at their 
base by the large connectivum. 
Fig. 19. Stamen of a species of Zygophyllum : a, the anther; b, the filament; 
c, the scale to which the filament adheres. 
Fig. 20. The one-celled anther and filament of Callitriche. 
Fig. 21. The stamen of Sparganium ramosum. 
Fig. 22. The stamen of Vaccinium amoenum ; a, the pores by which the anther 
bursts. 
Fig. 23. The anther of Begonia Evansiana : a, the oblique immersed cells ; 
5, the connectivum. 
Fig. 24. Anther of Cucumis saliva: a, seen from the front; 6, from behind; 
c, the connectivum ; d, the sinuous lobes of the anther. 
Fig. 25. Stamen of Hermannia flammea : a, filament ; b, scale to which the 
latter has grown. 
Fig. 26. Halved stamen of Synaphea dilatata; after Ferdinand Bauer: a, fila- 
ment; 6, connectivum ; c, single lobe of the anther after bursting. 
Fig. 27. Stamen of Eupomatia laurina, after the same. 
Fig. 28. Stamen of Cephalotus follicularis, after the same : a, a granular con- 
nectivum. 
Fig. 29. Stamen of Pterospora Andromedea : a, an appendage of the anther. 
Fig. 30. Stamen of Securinega nitida ; the cells opening transversely.
