Dichogamy is the maturing of pistils and stamens of a flower at different times. When this occurs in a self‐pollinated species, opportunities for self‐pollination are drastically reduced or eliminated altogether, thus making the plant practically cross‐pollinated. There are two forms of dichogamy: protogyny (stigma is receptive before the anther is mature to release the pollen) and protandry (pollen is released from the anther before the female is receptive).
