Plant help needed

There's a dyc (damned yellow composite, if you forgot) that is growing in dozens of locations (mostly roadsides) all around where I live. I'm fairly certain it's in the genus Hieracium. (All the plant people just sputtered out a humorless laugh. There may be anywhere between 200 to more than a thousand species in this very troublesome genus.) It is not hairy, like most hawkweeds. It has leaves all along the stem, more than half the way to the flowers--it looks like most hawkweeds have rosettes only, or just a few leaves up the stem.

Do I have a chance of identifying this thing to species?



My best guess is H. paniculatum, but I don't trust that, since that's a native species, and this thing is behaving like an alien invasive.

Me again- I got started looking, and check out the Canada Hawkweed...

Numerous toothed leaves on stem; no basal rosette at flower time; leaves alternate. Looks like a good candidate!
