11. Stamen of the same. 
12. Portion of stamen, earlier period ; in this the centre

vanced than 13. 
13. About same period. Still earlier, doubtful appear- 
ance of single cells at apices of the part to be the 
. cells; in this also there were partial appearances

2c. Portion of contents of the same. 
2d. 'T wo of the pollen grains of the same. 
3. Pistillum. 3a Ovulum. 35 Same, = vertical sec-

5a. Inner face of gland at the same period, the crura are
