470B) breaks into five cocci as it is formed of five carpels. The follicle resembles the legume in developing from a superior mono­carpellary ovary but the fruit dehisces along one suture (usually the ventral) only. Multiple. This is similar lo caryopsis in being one seeded and superior but peri­carp and seed coat are free from one another. The flower is the reproductive structure of flowering plants. 435) of Asclepiadaceae and Vinca of Apocynaceae show paired fruits from the same flower. It is a simple, fleshy but false fruit as it is surrounded by a fleshy thalamus which is edible while actual fruit lies within, e.g., apple, pear, loquat etc. There are numerous types of fruit, which can be grouped into three basic categories: simple fruits, aggregate fruits, and multiple fruits.

These changes may also be associated with structural changes within the ovary, viz., a multilocular and multiovular ovary may change into a unilocular and one-seeded one by the dissolution of some partition walls and non-development of some ovules. Brinjal is false as it has a persistent calyx and Dillenia (Fig. An aggregate fruit develops from one flower that has more than one ovary (more than one pistil).
