Section IV. — Fruit and Seed. 



§ 1. Seed- Vessels. 



220. After the flower comes the Fruit. The ovary of the flower becomes the 

 Seed-vessel (or Pericarp) in tlie fruit. The ovules are now seeds. 



221. A Simple Fruit is a seed-vessel formed by the ripening of one pistil (with 

 whatever may have grown fast to it in the flower, such as 

 the tube of the calyx in many cases, 217). Simple fruits 

 may be most conveniently classified into Fleshy Fruits, 

 Stone Fruits, and Dri/ Fruits. 



222. The principal sorts of fleshy fruits are the Berry, 

 the Pepo, and the Pome. 



223. A Berry is fleshy or pulpy throughout. Grapes, 

 tomatoes, gooseberries, currants, 

 and cranberries are good ex- 

 amples. (Fig- 198 shows a 

 cranberry cut in two.) Oranges 

 and lemons are only a kind of 

 berry with a thicker and leath- 

 ery rind. 



224. Tlie Pepo or Gourd Fruit 



(such as a squash, melon, cu- "'• ^'"'■ 



cumber, and bottle-gourd. Fig. 199) is only a sort of 

 berry with a harder rind. 



225. A Pome or Apple-Fruit is the well-known fruit of 

 the Apple, Pear, Quince, and Hawthorn. It comes from a compound pistil with 

 a coherent calyx-tube (that is, from such a flower as Fig. 194), and this calyx.
