post an unknown plant and see if others can provide a name

Just out of curiosity...

Any idea what this is?  I grew this from NARGS seedex seed in 2012 as Saussurea nepalensis... which it clearly is not.  The seedlings already looked "off" in the early days, compared to those grown by others here (and also by myself on a previous occasion).  This year, I was bemused to see it send up an upright stem that has now topped out at ~1m (39").   Until these yellow flowers started opening, I could have perhaps continued to think it might be some sort of not-rock-garden-material Saussurea but my credulity is all used up now, LOL!

Persistent Misnomers

This topic is dedicated to those long persistent misnomers that seem near impossible to correct. I start with one that I have personally worked on for the last 30 years or more.

There is an Allium widely distributed as Allium tanguticum (from China), a real species, but everything sold under this name (and I mean EVERYTHING) is Allium senescens ssp. montanum. There is a long story to this misnomer, but for the time being I'll skip the long story and jump to the crux of the problem.

Trifolium trichocephalum?

Hi,

I posted about this plant, that I grew from seed, some time ago but can't find the thread (the Search function doesn't work), so I will post again.  

This was grown as Trifolium trichocephalum (from NARGS seedex) and it has finally bloomed in its 3rd year from seed.  Can anyone who is familiar with it confirm the ID please?  I was counting on finding the old thread, so did not photograph the foliage, but can do so.  Here are the flowers, in any case:
