homogamy is (botany) fertilization of a flower by pollen from the same plant while cleistogamy is (botany) the production of flowers which do not open, and are self-fertilized in the bud.
Components. While androecium has anthers and filaments, gynoecium has stigma, style, and ovary.
Vexillary aestivation is the arrangement of corolla in which the anterior petal is innermost and posterior petal is outermost and largest. It is also called as descending imbricate. Papilionaceae flower shows vexillary aestivation. There is large petal which has two lobes fused.
– Androecium is the male reproductive unit made up of stamens. A stamen has a long stalk called a filament. There is a cluster of microsporangia called anther at the tip of the filament. … The androecium of Hibiscus is monadelphous as its filaments are merged in one bundle and anthers are free.

Cleistogamous Flowers. Cleistogamy means the formation of flowers that do not open (CL), and thus production of seeds is a result of autogamy. In contrast, flowers that open are called chasmogamous flowers (CH), and they have various types of breeding systems, depending on the taxon.
Cleistogamy is a type of automatic self-pollination of certain plants that can propagate by using non-opening, self-pollinating flowers. … The more common opposite of cleistogamy, or “closed marriage”, is called chasmogamy, or “open marriage”.
