In the figure given below the plant bears following two types of flowers

A- Chasmogamous flower(the flowers remain open, exposing anthers and stigmas).

B- Vleistogamous flowers(the flowers remain closed, so that anthers and stigmas are never exposed) following are the types of pollination that will occur in these flowers.

(i) Autogamy (within same flower )

(ii) Geitonogamy (different flowers of same plant)

(iii) Xenogamy (different plants)

It is a case of cleistogamy (a type of autogamy) in which some plants, like Commelina benga lenses, possess both chasmogamous and cleistogamous flowers.

In chasmogamous flowers, the flowers may undergo self-pollination or cross-pollination, while in cleistogamous flowers, the flowers undergo only self-pollination.
