[Found by googling ipheion "rolf fiedler", fourth link in the results.] IOW, "Ipheion" uniflorum is properly Tristagma uniflora. I had recently looked this up because I was entering a pot of 'Rolf Fiedler' in our local show of alpines and wanted to get the "right" name on the label. Google came through with the very message I had a dim recollection of. Poulsen: > More generally, I thought Tristagma was mostly a Chilean/Andean > Argentine genus that looks very similar to Ipheions. Don Elick told me that Rolf Fiedler, the man, was an Argentine rancher whose property was seized by the government and who subsequently went mad. To me, the obvious implication is that Ipheion/Tristagma/whatever 'Rolf Fiedler' is native to Argentina. -- Rodger Whitlock Victoria, British Columbia, Canada Maritime Zone 8, a cool Mediterranean climate on beautiful Vancouver Island
