Fic. 24.—Micropylar end of sac; male nucleus very close to spindle of egg 
nucleus, which is in anaphase stage; 600. 
Fic. 25.—Undivided egg with about 64-nucleate endosperm; other sacs in 
this ovary have embryos of about 16 cells; pollen tube contains three nuclei; 
600 
Fics. 26, 26, a, and 26, b.—Three sections of the same endosperm nucleus in 
metaphase; X 1000. 
IG. 27.—Two-celled embryo with pollen tube entering one synergid; 
600. ; 
Fic. 28.—Micropylar end of sac with two eggs and no synergids; X600. 
Fic. 29.—Diagram of sac with three, possibly five, eggs, one antipodal, and 
two fusing polars; X1os. 
Fic. 30.—One antipodal in the usual position, the group of six nuclei in the

tube entering; 1000 
Fic. 33.—The very common type of abnormal sac except that the antipo- 
dals are not exactly at the micropylar end of this sac; X105. 
Fic. 33, a—Egg apparatus of the same sac; 600.
