Yet another one that gives me no clue. 
that is sooooooo pretty even without bloom a good cv name would be lightstick
All these photographs were taken by my colleague who had a recent trip in Duars area. I will ask her if she can remember the particular place where she recorded all these cacti. Meanwhile I am attaching a couple of shots that suggest that this is a nursery.
That is really something ...,
I stick with Cleistocactus on this and still think it is samaipatanus. I wonder what caused it to begin losing it’s chlorophyll like that? This is indeed a rare find.
Found somewhat similar variegated one at -
