Most experts believe that Artemisia have all disk florets and no ray florets. The 15-20 inner florets (four of which are open and in focus in this example) are bisexual with both male (staminate) and female (pistillate) parts. The 6-10 edge florets (along the bottom of the image) are female (pistillate). | |
Another example. | More mature flowers. |
Both bisexual and female (pistillate) florets are visible in these images. | |
The style has two branches, which are covered with papillae on the outside and at the apex, forming brushlike structures. The five anthers are joined in a tube that surrounds the style, and the pollen is swept out of this tube by the stigma as the style elongates. This species is thought to be self-incompatible. |
