For plants, this relationship has resulted in more precise attraction of specific pollinators, facilitating the transfer of pollen to the stigmas of other plants and reducing the overall production of pollen. In contrast to anemophilous plants, which may produce around one million pollen grains per ovule, orchids typically produce a one-to-one ...
Orchids have developed highly specialized pollination systems, thus the chances of being pollinated are often scarce, so orchid flowers usually remain receptive for very long periods, rendering unpollinated flowers long-lasting in cultivation. Most orchids deliver pollen in a single mass.
These orchids do not produce nectar, and hide the pollen on a single anther under an anther cap; orchids are not visited by females, as females require both nectar and pollen as food provisions for their offspring, and visit other types of plants to obtain these resources.

One type of automatic self-pollination occurs in the orchid Ophrys apifera.One of the two pollinia bends itself towards the stigma.. Self-pollination is a form of pollination in which pollen arrives at the stigma of a flower (in flowering plants) or at the ovule (in gymnosperms) of the same plant.

Many orchids, including the Ophrys bee orchids, deceive male insects into pseudocopulation in this way, using them to transfer pollen. [23] For instance, the orchid Epipactis helleborine is physiologically and morphologically adapted to attract social wasps as their primary pollinators. Social wasps feed their larvae on insects such as ...
Cymbidium Orchid. Commonly known as "boat orchids," cymbidium orchids have smaller flowers compared to other orchid varieties, but can produce up to 30 blooms per spike.
