extranjera said:Fabulous! Thanks for posting these pics Tarev. Now I see how the one you got with the upside down umbrella bloom would lure the bugs and the pitchers would trap them. That 3rd picture with the beautiful red bloom is truly stunning.
Although the flowers would lure some insects to the traps, the traps have their own way of luring insects, such as coloration, scents and even fluorescence
All the flowers in the photos above are missing their petals. Here is Sarracenia alata with petals intact.
The flowers of pitcher plants are as interesting as the pitchers. In the photos above the parts that spread over the top are the sepals. The upside down umbrella is the style and stigmas. The stamens would be attached between the ovary and sepals, and when the pollen falls off it is caught in the cup formed by the pistil. An insect has to crawl under the petal to get inside where the pollen is, and when it does, it's beating wings scatters the pollen causing in to land on the stigmas. There is a cross section of the flower on this page so you can see how it works, so you can get a better idea of how it works.
