Heterogamy

(Science: plant biology) The condition in a flowering Plant species of having two or more types of flowers. For example: flowers which have only male parts along with flowers which have only female parts.

Compare: homogamy.

The condition in a flowering Plant species where both the male and female parts of the flower mature at the same time, so that the individual flower can pollinate itself. (Some species have come up with other obstacles to prevent that possibility, however.)
