9. Ditto acted on by iodine. 



10. A spore in emission 1-560, the nucellus has also escaped. 



1 1 . Transverse section very early, shows one of the cells 

 partly, the spores are at this time nearly or quite free. 



12. One spore (parent) and the tissue lining the septa. 



13. A parent spore, not divided yet, or yet nuclear. 



14. A parent spore, 3 green nuclei commencing. 



15. Do. do. nuclei not shewn, but the division has com- 

 menced. 



PI. CXVII. {Upper division.) 



1. Portion of female transversely, in this there are many of 

 the spores which have taken on themselves great powers 

 of growth, these are spherical and turgid, obviously of the 

 same structure as the smaller ones, even to the echinulate 

 dorsum : they contain a subtle invisible fluid ? the others 

 do not burst on pressure ; and have now their mature 

 form, although the amylaceous granules do not yet exist. 



2. A group of these larger spores, the males of authors. 



3. A transition form, both in size and turgidity. 



4. A smaller one, or real spore ? 



5. Do. under iodine, causing the outer, or parental part 

 to be thrown off, this shews the difference in size be- 

 tween these and the males of authors. Fig. at 2. 



6. 6. Very much enlarged. 



7. 7. Perfect spores of both kinds, measured, 1 inch object 

 glass. 



7a, 7a. Their sections. 



8. Very young parents, nucelli just commencing. 



9. Very young part of female, seen transversely, loculi now 

 solid, parent immersed in the brown cellular tissue, 

 not separable, containing a grumous fluid, it bursts on 

 slight pressure. 



10. Part of reproductive tissue ? and the parent spores. 

 PI. CXVII. (Lower division.) 



1. Young female, transverse, 



2. Male, immersed part.
