Thank you Janet. I spent a bit of time searching out links....I had just finished reading the info at Kews when I logged in here....I am leaning toward Villadia batesii more and more, but not Spiral Staircase, even though there is a great deal of variety among those plants, I just don't see the flattened leaf bases that show up in so many pictures. It may be a matter of "Fred is happy with his name and we don't care who his parents are"
