]5. All the envelopes removed and the parts of fructification longitudi¬ 
nally 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. 
17. 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 fecunda¬ 
tion ; 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.

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 7- 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.
