The shapes, colors and fragrances of orchids are the result of their coevolution with pollinators. Pictured is a flower Coryanthes leucocorys, species that has evolved one of the most fascinating mechanisms of attracting pollinators by means of a liquid-filled pouch.

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.
Euglossine bees pollinate orchids, but these are male bees collecting floral scents rather than females gathering nectar or pollen. Female orchid bees act as pollinators, but of flowers other than orchids. Eusocial bees such as honey bees need an abundant and steady pollen source to multiply. Honey bee pollinating a plum tree. Bees are the most ...
Dendrobium Orchid. There are as many as 1,800 different species of dendrobium orchids. These orchids like to grow in small pots and often have tall, top-heavy blooms that require staking for support.
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 ...
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.
The coughing, sneezing, headache-nightmare-of-an-event took place on April 4, when a 30-foot river birch tree was chopped down in a residential area.
Orchids that attract Euglossine bees secrete scented oils, but while accessing these, the bees slip and into a water-filled bucket. To escape the bucket, the bee must crawl up a narrow tunnel, during which the plant attaches pollen sacs onto its back. The escaped bee will visit another orchid and drop the pollen, fertilising it.
