Dichogamy, dī-kog′a-mi, n. an arrangement for preventing the self-fertilisation of hermaphrodite flowers, the stamens and stigmas ripening at different times.—adj.

Dichogamy, in flowers, the condition in which anthers and stigmas ripen at different times, whereby self-pollination is effectually prevented.

It is comparatively rare in hermaphrodite flowers for self-fertilization to occur, and the various forms of dichogamy, dimorphism and trimorphism are fitted to prevent this.

Dichogamy is the commoner case.

In Sabbatia, the large-flowered species of Epilobium, and strikingly in Clerodendron, the dichogamy is supplemented and perfected by movements of the stamens and style, one or both, adjusted to make sure of cross fertilization.
