Looks Like a Dandelion: Narrowleaf Hawksbeard

Below are a few identification notes.  Plants in the aster family have unique flowers (though familiar) with a vocabulary all their own.  I've tried to avoid using these technical terms and keep my notes very simple.

A.  On the left is a Dandelion flower head.  On the right is a Narrowleaf Hawksbeard flower head.    Each petal on both plants is a complete, or perfect flower with stamens and a pistil. 

B. Two layers of hairy bracts

C. Leaves changed size and shape as they ascend the stem.  Bottom of the picture corresponds to botrtom of the plant.

D. Leaves often have a pair of wings at their base.

If you want more details on Narrowleaf Hawksbeard, or want to dive deep into Aster terminology, consult the following sources.

I also like to consult the "The New Britton and Brown Illustrated Flora" by Henry A. Gleason, Ph.D.   Volume 3 has the Aster family in it.
