apex of the nucleus, 4, lens will scarcely demonstrate 
any cells except at i base, itis attached by a single

5. Long section of an ovule more advaced, embryonary sac 
distinctly cellular. 
6. Ovule viewed on its inner or raphal face, raphe evas- 
cular composed of fibres. 
7. Long section of ovulum more advanced. Cotyledons 
opposite the raphe. 
8. Portion of testa shewing the cellularity, of the nuclei. 
9. Section longitud. of seed, thro’ short diameter or at 
right angles with the axis. 
This development is remarkable for the evolution of the'em- 
bryo, at.a distance from the foramen and apex of the nucleus. 
The seeds have two integuments, testa and embryonary
