FRUIT.

Dor'sal Suture.— The outer suture. See Fig. 243. 
What name is given to those joints in ovaries at 
Fig. 248. 
which they open when the seeds are ripe ? How many 
sutures has a bean-pod? To which suture are the 
beans attached ? 
When an ovary opens spontaneously, and thus 
liberates its seeds, it is called a dehiscent ovary. 
When it does not so open, it is an indehiscent ovary. 
Are there any indehiscent ovaries among the fruits 
of the garden or farm ? 
Mention all the dehiscent ovaries you can think of. 
Again turn to Fig. 168, and compare it with Fig. 
244. 
Obtain the ripe fruit of Iris [flower-de-luce], and 
compare it with the pictures. Is it a dehiscent or 
indehiscent fruit ? Can you find sutures at which the 
carpels open ? What do you call the suture at which 
the seeds are attached ? What do you call the line 
in the outer wall of each carpel, opposite the ventral 
suture %
