  2. Marah macrocarpa - Wikipedia

    en.wikipedia.org/wiki/Marah_macrocarpa

    Male flowers appear in open clusters while females flowers, distinguished by a swollen base, usually appear individually. The plant is self-fertile, i.e. pollen from the male flowers can fertilise the female flowers on the same plant; pollination is by insects. Fruit Marah macrocarpa fruit

  3. Marah oreganus - Wikipedia

    en.wikipedia.org/wiki/Marah_oreganus

    The flower can vary in color from yellowish green to cream to white. Flowers appear soon after the vine emerges. The flowers are monoecious, that is, individual flowers are either male or female, but both sexes can be found on the same plant. Male flowers appear in open spikes while females flowers, distinguished by a swollen base, usually ...

  4. Cucumber - Wikipedia

    en.wikipedia.org/wiki/Cucumber

    Cucumbers may also be pollinated via bumblebees and several other bee species. Most cucumbers that require pollination are self-incompatible, thus requiring the pollen of another plant in order to form seeds and fruit. [10] Some self-compatible cultivars exist that are related to the 'Lemon cucumber' cultivar. [10]

  5. Plant reproductive morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_reproductive_morphology

    Androdioecious: having male flowers on some plants, bisexual ones on others. [6] Androecious: having only male flowers (the male of a dioecious population); producing pollen but no seed. [16] Androgynous: see bisexual. [6] Androgynomonoecious: having male, female, and bisexual flowers on the same plant, also called trimonoecious. [16]

  6. Monoecy - Wikipedia

    en.wikipedia.org/wiki/Monoecy

    Monoecy often co-occurs with anemophily, [2] because it prevents self-pollination of individual flowers and reduces the probability of self-pollination between male and female flowers on the same plant. [4]: 32 Monoecy in angiosperms has been of interest for evolutionary biologists since Charles Darwin. [5]

  7. Echinocystis - Wikipedia

    en.wikipedia.org/wiki/Echinocystis

    The sole species is E. lobata, commonly called wild cucumber and prickly cucumber. It is an annual, sprawling plant that is native to North America . Sicyos angulatus , common name "bur cucumber", is an annual plant with a similar clinging vine growth but different-appearing flowers and seed pods.

  8. Sexual selection in flowering plants - Wikipedia

    en.wikipedia.org/wiki/Sexual_selection_in...

    For example, male inflorescence in plants often produce more flowers than females . Furthermore, pollen export and ultimately paternity, often increases with flower number, even for plants with hermaphroditic flowers. Retention of older flowers with no pollinator rewards can lead to increased pollinator visitation rate and increased pollen removal.

  9. Sexual system - Wikipedia

    en.wikipedia.org/wiki/Sexual_system

    a sexual system for plants when female, hermaphrodite, and gynomonoecious plants coexist in the same population. [25]: 360 Monoicy: one of the main sexual systems in bryophytes. [18] In monoicy male and female sex organs are present in the same gametophyte. [19] Monoecy: a sexual system in which male and female flowers are present on the same ...
