PHIL Image 243
 
ID#:243
Description:This is a scanning electron micrograph of an Ambrosia trifida plant, or more commonly known as ragweed. See PHIL 11199 for a black and White version of this image.

When ragweed pollen is disbursed, many people have a reaction, but because they don't see the tiny flowers on the ragweed, they assume it's the pollen from the larger flowered goldenrod, which blooms at the same time. Note the dispersed pollen granules.
