Scilla ID

[Lori S.]

I would be most appreciative if someone could identify this scilla.   
I believe I bought the bulbs as Scilla bifolia, though it doesn't seem to be that, now that I've started looking at it more critically!  I'm starting to think it is Scilla tubergeniana (S. mischtshenkoana)... perhaps?  (I hope these photos are clear enough... it won't be in bloom again until perhaps month end, but I could get better photos then, if need be.)
Thank you!

It would be much easier to identify  if you send a closeup of the flower with the pedical and bract.

Thank you, Oron.  I'll see if I can find a clear photo that can be enlarged enough.  Otherwise, I may have to revisit this with a new photo later on when they are in bloom again.

I've zoomed in on a photo - I hope it shows the pedicel well enough.
Edit: photo added to show stem bracts... I hope?

It certainly looks like S. mischtschenkoana, at first I thought it might be an hybrid but seeing it closely it isn't.

Thank you very much, Oron!  If you don't mind me asking, what characteristics, in particular, might define it as S. mischtschenkoana?  (Again and again, I see that I need more, and better, reference books! )

Lori,
This species has quite a few characteristics:

Shape of the flower is flat [open, often upright], color white or very pale blue with a  darker strip in the middle, back side of each petal. 2-6 flowers per stem.
Pollen color is yellowish, not blue.
Flowers start to open when the leaves are not fully grown, usually 3-4 leaves, relatively wide for these group of Scilla.
Height of the plant is 10-15 cm.

Thanks again!
