Pollen Description Orchids have pollen, but it’s not the free-floating variety common to many other types of flowers. Instead, orchid pollen is sticky and remains in its pollen packet until a pollinator, such as a bee, whisks it away.
For sensitive people, exposure to airborne pollen triggers a cascade of seasonal allergy symptoms, sometimes called hay fever, such as a runny nose, sneezing, and itching. Orchids have pollen. Despite having pollen, orchids are regarded as one of the most allergy-friendly flowers that exist.
Why do orchids have flowers?
The reason orchids have flowers is for reproduction, and in many cases, pollination is the means of propagation. Insects, birds and even mammals can transfer pollen from orchid blossoms to other areas to instigate the growth of new orchid plants.
So, do all orchids have pollinia?
Most orchids have a single fertile anther (flower structure where pollen is produced) located at the tip of the column. In most orchids, pollen is not loose and granular when ripe but rather is packed into a waxy mass called a pollinium. Pollinia usually occur in pairs, but in some species they are found in groups of up to eight.
How do insects pollinate orchids?
As the insect extends its proboscis (elongated mouthpart) to drink the nectar, pollen is deposited onto the body of the insect. When the insect visits the flowers of another orchid of the same species, it transfers the pollen and fertilises the flower, which leads to the production of seeds.
The most common spider mite recognized as a persistent pest of orchids is the common two-spotted spider mite (Tetranychus urticae), but the carmine spider mite (Tetranychus cinnabarinus) may be an unrecognized pest species in North America.
