These two I received in swaps; one I think mislabeled and the other the tag was lost and doesn't seem to match any of the "floating tags". Please help?

Was supposed to be Centaurea montana but I only see that in a blue - looks like primrose; can they have branching habit?:

{{gwi:316132}}




Completely unknown - doesn't look like the Painter's Pallet or Leibnitzia anandria that left-over labels might suggest:

{{gwi:316133}}


{{gwi:316134}}




Neither looks like any of the weeds I germinated plenty of this year. Thanks for any help!
