Erythronium 'Sundisc' parents

Regarding Paige Woodward's inquiry:
Here is a quote from an old descriptive catalog, copyright 1996, 
prepared by Antoine Hoog when he was in business with Jan Dix:

"'Sundisc' raised by Mr W. P. van Eeden from a 'Pagoda' seedling; 
exciting new hybrid; flowers slightly darker than in 'Pagoda'' less 
drooping so making the inside better visible; leaves brown, very dark 
and unusual, could prove to be very effective in bedding displays."

Further to this, 'Pagoda' is a hybrid of Erythronium tuolumnense and 
E. californicum 'White Beauty'. Apparently the pollen parent of 
'Sundisc' is not recorded, but it might be 'Pagoda' selfed. I don't 
know whether Erythronium is self-fertile. I have not found 'Sundisc' 
to increase as well as 'Citronella' and 'Pagoda'.

Incidentally, just this morning I saw germinating seedlings from seed 
I saved of a beautiful small pink-flowered Erythronium hybrid raised 
by Walter Blom and later purchased and propagated for sale by Diana 
Reeck of Collectors Nursery. I assume one of the parents of the Blom 
hybrid is E. revolutum, but the hybrid's flowers are lighter in color 
and more profuse. I don't know whether the seed I obtained is selfed 
or perhaps the pollen parent was some other plant, but there are no 
other erythroniums in the immediate vicinity of this plant.
