I have just come about the same question what "Rolf Fiedler" is. Here in Germany they do behave totaly different then I. uniflorum. They are not hardy at all and have to be grown under frostfree conditions. Leaves are wider, flowers larger. I. uniflorum is perfectly hardy and is spreading very well, sometimes to good! There is still no publication about the problem. Tristagma peregrinans occures a lot more north in Uruguay, while "Rolf Fiedler" is from Argentinia. I think you have to see both plants as living objects to resolve this. Unfortunatly I don´t know a source for Tristagma peregrinans. Already over 10 years ago the problem was the same for Brian Mathew, who wrote a short not in his Bulb newsletter (The Bulb Newsletter 21:4, 1998). Changing of all Ipheions to Tristagma needs more investigation, too. I haven`t seen a paper dealing with it. Plantlist.Org is very good but not free of mistakes! Because they are changing the genus quite regularly one should have a good look to the Publication first. Still, Alberto might know both species and give us a solution.
