New (evolutionary) aspects are also expected by comparison of symmetry types with other features, such as genetics of breeding systems via dichogamy (Kalisz et al.
Dichogamy (time delay between expression of male and female functions within flowers) and pollinator movements on inflorescences can create different transfer probabilities for pollen at different positions and thus influence sex allocation.
Self-pollination can be favored by cleistogamy, chasmogamy and self-compatibility, while cross pollination can be favored by dichogamy, herkogamy and self-incompatibility (Frankel & Galun, 1977).
nervosa presents dichogamy and it could be that abortion is a consequence of self-incompatibility rather than herbivore damage alone.
The influence of pollinator directionality on fruit and seed set will depend on the order of floral development, the degree of dichogamy, and the level of inbreeding depression.
Dichogamy may be selected as a means to reduce the level of self-pollination (Darwin 1876), and/or to reduce interference between the dissemination and receipt of pollen (Lloyd and Yates 1982; Lloyd and Webb 1986; Bertin 1993).
Low-copy nuclear DNA, phylogeny and the evolution of dichogamy in the betel nut palms and their relatives (Arecinae; Arecaceae).
The failure of individual flowers to self may be due to [TABULAR DATA FOR TABLE 3 OMITTED] dichogamy, or temporal separation of pollen release and stigma receptivity.
Second, SC plants commonly exhibit floral traits, particularly the spatial or temporal separation of male and female organs (herkogamy, dichogamy, certain manifestations of monoecy) that usually have been assumed to have evolved to reduce inbreeding.
Dichogamy is remarkably widespread within the angiosperms (Bertin

In addition, we summarized the available data on compatibility, presence and type of dichogamy, observed floral visitors, presence of floral rewards, and currently known pollination systems.
