FIG. 1 29. Raspberries, a fruit 

 which is made up of a collection 

 of fleshy pistils. 



of an angiosperm, in contrast to those of a gymnosperm, are 

 inclosed in an ovulary commonly called a pod or capsule, as 

 in the bean, horse-chestnut, hickory nut, and watermelon. 

 The term " angiosperm " means " hidden or covered seed," 

 referring to the fact that the seeds are inclosed by a pod, 

 fleshy fruit, or other covering. 



The fruit. The term "fruit" is commonly used to desig- 

 nate a great variety of organs that are developed as a result 

 of the flowering and pollination of plants. The direct result 

 of pollination and fertilization is the production of the seed. 

 The indirect effect of pollination is the further development of 

 adjacent structures. Primarily the fruit is the enlarged pistil 

 or ovulary ; but in many cases the calyx and the receptacle also 

 enlarge and form a part of the fruit sometimes most of it.
