This Stachys (I presume it is a Stachys) did I collect in Caucasus some years ago. It is very similar to S. macrantha but not quite. The leaves are very soft and downy and it grows in moist soil here!
I would love to give it a name if I could! It is certainly like Stachys macrantha. Have you considered posting it at SRGC?
