A study of dichogamy in Acer saccharum Marsh. (sugar maple) has shown that both protandry and protogyny occur in this species. The two conditions were represented equally in the population investigated. Synchronization of blooming periods of flowers of opposite sexes resulted in reciprocal pollination between trees with different dichogamous conditions.

Dichogamy, gender variation and bet-hedging inPseudowintera colorata
Evolutionary Ecology, 1991Temporal patterns of variability in the longevity of the male and female phases of individual flowers and in the gender expression of plants of a dichogamous New Zealand tree,Pseudowintera colorata (Winteraceae), were documented in field studies. Two measures for the duration of phases in a dichogamous flower are distinguished; the nominal phases based

Evidence of Dichogamy in Santalum album L.
Journal of Integrative Plant Biology, 2006AbstractFlowering, fruit set, embryological development, and pollination trials were investigated in Santalum album L. Each ovary may have three to four ovules. Microsporogenesis and megasporogenesis in the same flower were synchronized at the earlier stages of flower development.

Functional analysis of synchronous dichogamy in flowering rush, Butomus umbellatus (Butomaceae)
American Journal of Botany, 2001Dichogamy is one of the most widespread floral mechanisms in flowering plants and is thought to have evolved to reduce interference between pollen import and export within flowers, especially self‐pollination. Self‐pollination between flowers may also be reduced if dichogamy is synchronous among flowers on an inflorescence. The analysis of dichogamy at

Pelorisation. Dimorphismus. Trimorphismus. Dichogamie
1885Man beobachtet nicht selten bei manchen Bluthen eine absonderliche, gewohnlich ebenmassige, aber zuweilen auch zur Monstrositat ausartende Formentwickelung theils durch Verlangerung der Axe, theils durch Vervielfaltigung der Bluthentheile oder Umwandlung eines Bluthenblattkreises in den anderen oder durch Entwickelung neuer Bluthen- und Blattknospen in

Abstract Zygophyllum fabago is a species within the arid-adapted family Zygophyllaceae. The species is characterized by the co-occurrence of dichogamy and herkogamy. In order to understand the effect of these two complementary anti-selfing mechanisms in reproductive success, we conducted a detailed study of floral biology in Z. fabago.

Plant sexual systems, dichogamy, and herkogamy in the Venezuelan Central Plain
Flora - Morphology, Distribution, Functional Ecology of Plants, 2005Abstract Sexual system, temporal variation in sex expression, and herkogamy were evaluated in 210 plant species in the Venezuelan Central Plain (VCP). This analysis was conducted considering the life forms, habitats, flowering time, pollination systems, and dispersal syndromes of the plant species. Hermaphrodite species dominated the community (75.2%;

Hermaphroditism and dichogamy in Stilbocarpa polaris (Araliaceae) on Campbell Island
New Zealand Journal of Botany, 2012Since its scientific discovery in 1844, the breeding system of Stilbocarpa polaris (Araliaceae) has been described as polygamo‐dioecious with either unisexual or hermaphroditic and female flowers. A short study of flower sex expression, on subantarctic Campbell Island, found evidence that all
