Tristagma

Tristagma is a genus of South American plants in the onion subfamily with the Amaryllis family. It is native to South America (Peru, Argentina, Chile and Uruguay) but one of the species (T. uniflorum) has become naturalized in various other places. Several names have been coined using the name Tristagma but referring to species now considered better suited other genera (Beauverdia, Leucocoryne, and Nothoscordum).
