Thanks, Tobias.
Many years ago, before I got interested in Phrags, I remember seeing a plant with the name Phrag. hirtzii. What I remember is a brown-ish color with fairly long, very twisted petals, probably about the size of richteri or maybe a little smaller. I don't remember the pouch shape being like this, but as I said, it was before I was into Phrags. Anyway, this is similar to my memory, and of course, ever since being interested in Phrags, I've never again seen a hirtzii for sale.
