IN FLOWERING PLANTS. 203 
= 
Along the axis of the septum a broad line of vessels run. 
The ovula are pendulous from the top of each cell: they are 
funiculate (funiculo-brevi crasso) the coats are very distinct, as 
well as their openings; and these are directed outwards and 
upwards. At an early period they are overlapped by a some- 
- what tongue-shaped cellular production from the placenta, 
which completely covers over the foramen. The ovula are in 
addition more or less immersed in rigid simple hairs, most 
_of which appear to arise from the base of each cell. 
In their development they agree with other instances. 
The raphe often displaced, is always however next the axis, 
at the chalaza it becomes ramified over the outer surface of 
the seed. The ramifications proceeding upwards towards the 
foramen. 
1. Female flower: viewed parallel to each carpellum. 
2. Ditto, viewed laterally. 
3. Longest section of ovary, parallel to a carpellum. 
4. Ditto placental, plates reflexed to show the situation 
of the foramen. 
5. Ovulum viewed externally 
6. Ditto internal face 
7. Ditto front view, placental plate reflexed. 
8. Ditto longest section through testa. 
9. Ditto through both coats. 
10. Apex of young fruit, with abortive and fecundated 
ovulum. : 
. Longest section of young ovule after fecundation; a. 
testa; b. inner tegumen ; c. nucleus; d. its exca- 
vation. 
12. More advanced, with barren ovulum; a. testa; 5. 
inner teg.; c. nucleus; d. embryonary sac; e. its 
excavation ; f. portion of raphe. 
More advanced, section parallel to true faces of 
seed, the others are alternate; a. b. c. d. have same 
- references ; e. embryo ; f. chalaza. 
14. Section of testa, to show the disposition of its raphe 
> . and chalaza. 
15. Nearly mature fruit, front view. 
with placental plates.
