Echinops niveus
about 3' feet tall, leaves very sharp like thistle, clusters of small white flowers on the end of the stems
montane forest
I spotted this in the forest on the slopes of Mount Elgon. Unfortunately, this is the only photo I have.
May such type article help you...

It does look like your suggestion Ashish but the range doesn't fit. Perhaps it's not native. I wish I had some better photos of the leaves.
