 fruits that are indehiscent.

 mesocarp, and inside is 

 the juicy endocarp,^ in

 aided in their efforts to 

 grow by the succulent 

 flesh of the fruit, which affords them moisture 

 and nutriment. The hazel-nut is a fruit of 

 another texture altogether. The hard shell is the 

 pericarp, and the one or two seeds \\ithin it must
