Fig. 51. The nucleus of the initial cell is in process of division. X 
335-—Fig. 52. Three cells have been derived from the initial cell; the 
mother-cell has somewhat enlarged. The nucellus is long and narrow.

Fig. 53. Longitudinal section of young ovule. The initial cell is 
very large, reaching almost the entire length of the nucellus. This 
figure plainly Shows that the bulk of the nucellus, aside from the epi- 
dermis, owes its origin to the hypodermal layer of cells. X 335-

ends of the synergide is a star-shaped protoplasmic mass. X 260. |

cells lies almost in the plane of the paper. The nucleus indicated by 
dotted line could be seen by focusing down. X 335:
