Fig. io. — Pair of androcytes: blepharoplast undergoing fission in upper 

 cell; two blepharoplast granules resulted from fission in lower cell. 



Fig. ii. — Pair of androcytes showing elongation of one blepharoplast 

 granule. 



Fig. 12. — Androcyte; slightly later stage. 



Fig. 13. — Blepharoplast granules multiplying. 



Fig. 14. — Later stage; granules somewhat coalesced. 



Fig. 15. — Nucleus moving against blepharoplast. 



Fig. 16. — Nucleus elongating by side of blepharoplast; blepharoplast 



granules becoming coalesced. 



Fig. 17. — Later stage; blepharoplast and nucleus becoming closely asso- 

 ciated. 



Fig. 18. — Cell like that of fig. 17 viewed from direction indicated by 

 arrow; blepharoplast lying along edge of flattened point of nucleus. 



Fig. 19. — Later stage; blepharoplast still irregular in outline; boundary 

 between nucleus and blepharoplast indistinguishable. 



Fig. 20. — Mature spermatozoid ready to escape from antheridium.
