[13] These flowers typically emit scents reminiscent of decaying organic materials, excrement, or carrion, which attract flies seeking food or suitable sites for egg deposition ...
A pollinium (pl.: pollinia) is a coherent mass of pollen grains in a plant that are the product of only one anther, but are transferred, during pollination, as a single unit. [1] [2] This is regularly seen in plants such as orchids and many species of milkweeds (Asclepiadoideae). Usage of the term differs: in some orchids two masses of pollen ...
The orchid uses scent to attract male wasps which pollinate the flowers as they attempt to mate with them. The scent released by the flowers mimic female sexual pheromones. [9] Both of the wasp species which pollinate fly orchids in the UK feed on Umbellifer flowers as adults and on froghopper nymphs as larvae.
In another legume, soybeans, the flowers open and remain receptive to insect cross pollination during the day. If this is not accomplished, the flowers self-pollinate as they are closing. Among other plants that can self-pollinate are many kinds of orchids, peas, sunflowers and tridax. Most of the self-pollinating plants have small, relatively ...
Orchids can be found on every continent except Antarctica. ... The pouch shape aids in pollination. Pollinators are attracted to the flower’s sweet scent and fall into the pouch, getting trapped ...

Ornithophily or bird pollination is the pollination of flowering plants by birds. Chiropterophily or bat pollination is the pollination of flowering plants by bats. Plants adapted to use bats or moths as pollinators typically have white petals, strong scent and flower at night, whereas plants that use birds as pollinators tend to produce ...
