Most of the distal portion of the ligule has been removed from this floret.

The stamens arise from the inner surface of the corolla tube and the anthers form another tube around the style.  The anthers dehisce introrsely with the pollen pushed out of the anther tube by the growth of the style.  The styles are fertile and branched.  Note the white pappus.
