cleistogamy


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

cleistogamy

the production of small, inconspicuous flowers in which self-fertilization occurs before the flowers open. For example, the violet forms large, showy, cross-pollinating flowers, but also forms cleistogamic flowers late in the summer.
