FRUIT, OR SEED CASE. 49 
is much increased in size at its tube, so as to enclose 
and shut in the ovaries, and yet not combine with them 
into one body; this is well seen in the fruit, or hip of 
the Dog Rose, and other Roses (pl. 15. f. 1.). 
It is necessary therefore to examine carefully the 
real structure of an ovary, which appears to be inferior 
or adherent to the calyx; and in order to do so, the 
flower should be cut in a perpendicular direction, as 
represented in the figure referred to. 
OF THE STYLE, AND STIGMA. 
73. The Style usually takes its rise from the upper 
part of the ovary, but it may also arise from its base, 
as seen in pl. 16. f. 15. The styles of several ovaries 
may be separate from each other; as for example, in 
the Chickweed, Pink (f.18.), Sweet William, &. or 
they may be united, as in the Mallow (f. 4. s.), Gera- 
nium (f. 3. s.), Lavender, Sage (f. 17. s.), &c. In like 
manner the stigmas of several styles may be free, even 
when these last are united, as in the Geranium (f. 3. s¢.); 
or they may be united into one head, as in the Lily 
(f. 8. st.), Heath, Fuschia (pl. 13. f. 9. s¢.), &e. 
In the Poppy (pl. 16. f. 16.) the styles are absent, 
and the stigmas (st.) are seen in the form of hairy rays 
passing from the centre to the circumference of the 
top of the compound ovary. 
OF THE FRUIT. 
74. The Flower begins to undergo several changes 
as soon as the ovules have been fertilized in the 
ovary.
