Areas of origin of I.sibirica are very large: not only Europe and Siberia,
Caucasus too, even Trans-Caucasus, in particular Armenia, where many arils
originated.

How it is like many popular books!
Pensylvanicum, that grow in Ussuriland (Dahuria), is lilium, known as 
L. dahuricum.
It is one of historical curiosities.
When this specie got England from Russia mid 17'th, it was seemed to
M.Catsby(?) it is from America, therefore 1804 J. Ker-Gawler described it as
L. pensylvanicum. 1809 he redescribed it as L. dahuricum, and then more 100
years it was known as dahuricum. Now a priority of erroneous name is 
reestablished.
I don't know any other pensylvanicum that grow in Siberia.
