An Evolutionary Basis for Pollination Ecology
It appears that cleistogamy mainly occurs in homogamous flowers, but some
species appear to be very flexible: also dichogamous species (whether or not
with developments towards dicliny) can develop cleistogamy under unfavourable
...
Dicliny. DEFINITIONS A flower is considered to be male when it bears an
androecium (stamens, the microsporangia) with viable pollen (microspores)
capable of forming fertile pollen tubes (male gametophytes). A flower is
considered to be ...

Major Evolutionary Transitions in Flowering Plant Reproduction
Subsequent selection against attractive structures would then intensify the
correlation with wind pollination. Sexual Traits Our finding that wind pollination is
strongly correlated with dicliny and dioecy is in accord with several previous
studies ...

are questionable -dicliny, dioecious - mixed pollination - pollen release under dry
conditions - associations with certain habitats (e.g. high altitudes and latitudes) (?
) - high outcrossing rates (low in selfing species) - dicliny, dioecious - pollen ...
Amots Dafni, Michael Hesse, Ettore Pacini, 2000
The sex distribution of all gymnospermous groups was consistently of the
unisexual type (i.e., dicliny prevailed). The Gnetatae provide clues as regards
changes in this pattern, some forms exhibiting an incipient (but not functional)
monocliny ...
One of the forms the distribution of the reproductive organs may take is often
referred to as 'polygamy' (which term is not unequivocal, but there is apparently
no better name available), i.e., dicliny and more or less advanced monocliny
exists in ...

The pollination of flowers by insects
Dicliny in these groups is not primitive, but is a derived phenomenon, facilitating,
in some genera, second order protogyny between flower specialists in an
integrated, monoecious trap. In a similar way, tropical, entomophilous Fagaceae
also ...

Pollination of Cultivated Plants in the Tropics
The sorts of breeding systems included are included in the term dicliny. Within
dicliny, dioecy is the most marked form of sexual separation with plants which are
pollen donors only (males) and others which are pollen recipients (seed ...
