Dichogamy refers to maturation of sex organs in plants at different times. It has been monitored in plants for over 250 years. It is not a simple process and has many aspects. It is widespread in angiosperms and mainly divided in two main types; proterandry and proterogyny. In degree it may be partial (incomplete) or complete. Dichogamy may be intrafloral or interfloral. In former, it is expressed within a flower, in latter, it exists among flowers in diclinous species. It can be interpreted as a floral mechanism favouring cross-pollination. Proterandry and proterogyny are safeguards against self-pollination. In this review, we discussed patterns of occurrence and importance of dichogamy in the light of previous studies.
