PART I. ORGANOGRAPHY. 



(9) The Berry. This is a fruit which has a thin, membran- 

 ous rind, and all the rest of the pericarp is succulent. The fruits 

 of the Belladonna, Grape and Gooseberry are illustrations. 

 Berries may be one, two or even many celled, and they may be 

 derived either from a pistil which is free from the calyx or from 

 one which has an adherent calyx. In the former case the berry 

 is called superior, in the latter inferior. Fig. 320 represents 

 the berry of Belladonna. 



(10) The Hesperidhtm is a fruit like the orange, Lemon and 

 Lime. It resembles a superior berry, but differs from one in 

 having a leathery rind containing numerous oil glands. See 

 Fig. 322.

(n) The Pcpo. This is a fleshy fruit like that of the Gourd, 

 Melon and Cucumber, having a hardened or tough rind, Fig. 323. 



(12) The Pome. This is a fleshy fruit, the chief bulk of 

 which consists of adherent, fleshy calyx, as the Quince, Pear and 

 Apple, Fig. 324. 



The more important dehiscent fruits which are the product of 

 a single pistil are the following : 



(1) The Follicle. This is a one-carpelled, dry fruit, that 

 dehisces along the ventral suture, as the fruit of the Columbine, 



Fig. 3 2 5- 



(2) The Legume. This differs from the follicle only in the 

 fact that the dehiscence takes place along the dorsal as well as 

 the ventral suture, forming two valves. This form of fruit is
