Another mixed mating system is referred to as dimorphic cleistogamy.
The obvious disadvantage of cleistogamy is that self-fertilization occurs, which may suppress the creation of genetically superior plants.
In addition to chasmogamy and cleistogamy, many plant species possess a mixed breeding system that utilizes both chasmogamous and cleistogamous flowers.
In contrast to chasmogamous flowers, are minute, bud-like cleistogamous ( " closed marriage " ) flowers, and pollination of cleistogamous flowers is cleistogamy.
This breeding system has been referred to under multiple names including true cleistogamy, Rarely, the two flowers have also been documented as being both spatially and temporally separated.
The principal advantage of cleistogamy is that it requires less plant resources to produce seeds than does chasmogamy because development of petals, nectar and large amounts of pollen are not required.
The more common opposite of cleistogamy, or " closed marriage, " is called chasmogamy, or " open marriage . " Virtually all plants that produce cleistogamous flowers also produce chasmogamous ones.
This efficiency makes cleistogamy particularly useful for seed production on unfavorable sites or adverse conditions . " Impatiens capensis, " for example, has been observed to produce only cleistogamous flowers after being severely damaged by grazing and to maintain populations on unfavorable sites with only cleistogamous flowers.
