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.
