In some cases, orchids and their pollinators have become so interdependent that their existence is mutually exclusive. [4] Pollination mechanisms resulting from this coevolution generally benefit both parties: pollinators obtain nectar from the flowers, while orchids gain pollen transfer.
There's a fragile beauty in both orchids and African violets. But orchids have to be tough. There are over 30,000 species known worldwide and they have a long history.
Why Orchid Blooms Fall Off Too Soon. Orchid blooms drop off eventually from natural causes, of course, but if the flowers are falling off prematurely, there may be a problem. 1. Sudden Temperature ...
Baltimore Checkerspot (Euphydryas phaeton) nectaring at daisy (Argyranthemum)Pollination syndromes are suites of flower traits that have evolved in response to natural selection imposed by different pollen vectors, which can be abiotic (wind and water) or biotic, such as birds, bees, flies, and so forth through a process called pollinator-mediated selection.
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 ...

At that same moment, the small packets containing the pollen of the orchid get pressed against the thorax of the bee. However, the glue on the pollen packets does not set immediately, so the orchid keeps the bee trapped until the glue has set. Once the glue has set, the bee is let free and he can now dry his wings and fly off.
