From IPNI there are two listings:

Dear Mary Sue:
                    In Nothoscordum you find
Nothoscordum felipponei (Ipheion sellowianum)
Nothoscordum hirtellum (Ipheion hirtellum)
Nothoscordum osteni
Nothoscordum vittatum (Ipheion vittatum)
Nothoscordum bivalve (L.) Britton supposedly the same species in Texas and 
in Argentina
Nothoscordum fragrans (N. inodorum, the frightful weed), N. gracile
Nothoscordum montevidense
Nothoscordum bonariense
and scores of others less known. Some interesting images in John Lonsdale 

                   In Ipheion you find
Ipheion uniflorum, several cultivars and sizes
Ipheion recurvifolium (distributed under "Ipheion sessile", that is not 
actually in cultivation)
Ipheion "Rolf Fiedler"
Ipheion tweedianum
and a few other species not yet described

                  In Tristagma you find

Tristagma bivalve ( Lindl. ) Traub (Ipheion bivalve ( Lindl. ) Traub) that 
grows in the mountains above Santiago, Chile and is not find in Argentina or 
Uruguay. T. bivalve looks like a several flowered medium sized Ipheion 
Nothoscordum bivalve has a tall scape with minute  flowers not unlike 
Nothoscordum "inodorum" and two broadish "valves" (bracts) much like a 
crab's claws.

You sound surprised to learn that they have included these plants in 
Ornithogalum besides the accostumed musical chairs among genera but as 
pressed specimens they all look much the same. In herbariums all the 
unidentified specimens are piled as back work hence a name given with a 
little accuracy can be a blessing. Only recently with the cultivation of 
living plants (and most of them by amateurs) is that knowledge of these 
plants has advanced. At Misssouri I had the chance to work in the famous 
Traub herbarium. It comprises lots of specimens but all look the same. Like 
if Traub had collected and pressed all the flowers in a clump and produced 
from them a number of species. . From this situation is that the confusion 
from the past drags in into the present. . Another disaster area is when 
amateurs mess around. I suspect this was the case with the "Rolf Fiedler"/T. 
peregrinans previous thread. More later.
All the best
