The Orchid's Pollen Bundles
With the rest of the blossom torn away, the orchid's pollen bundles and its sticky stigma may be seen in this photograph print. These bundles attach themselves to the head of the insect, sticking out like a horn so that the next flower visited will be sure to receive its charge of pollen. The sticky stigma can be seen in this print directly beneath the two pollen bundles at the top. The petal itself of course is bent down to show the structure, but it can be seen that the colors and all of the lines lead to the central point as if to guide the bee.
