15. All the envelopes removed and the parts of fructification longitudinally
cut through; magnified 4 diameters.
16. The pollen-mass of one cell of the anther, with its whole caudicula,
and the stigmatic gland adhering to it; magnified 4 diameters.
1/. A transverse section of the anther; magnified 8 diameters.
18. One scale of the pollen-mass; magnified 25 diameters.
19. Some pollen-grains ; magnified 200 diameters.
20. A front view of one of the stigmatic glands, in the state of fecundation
; magnified 8 diameters.
21. Some of the gelatinous corpuscles found in the fluid of that gland ;
magnified 200 diameters.
22. A front view of the spoon-like termination of one of the stigmatic
protruding lobes; magnified 8 diameters.
23. A side view of the same, with the stigmatic gland immersed in it, in
the act of fecundation; magnified 8 diameters.
24. A longitudinal section of one of these stigmatic lobes; magnified 8
diameters.
25. Some of the utricular vessels, the linings of the above lobe, in the
state they appear during fecundation ; magnified 200 diameters.
26. A small portion of the inner surface of the arched part of the stigma;
magnified 100 diameters.
2/. Transverse section of one of the additional lobes or parts, which
Mr. Bauer thinks may perhaps be considered as sterile filaments;
the section is made below the middle, up to which runs a cord of
vessels like filaments; magnified 16 diameters.
28. An inside view of one of the lateral sepals ; magnified 2 diameters.
29. A small portion of the epidermis of the outer surface of the sepals,
with the cuticular glands, which are the same as on the outside
of the leaves ; magnified 100 diameters.
30. Transverse section of the ovarium ; magnified 4 diameters.
