Robert,
I doubt very much that this photo is correctly labelled. (I'm suspicious of the other one too.) The form of
Allium obliquum is very different than shown, with the fairly broad leaves alternating up the stems, and the flowers are yellow-green, not whitish as in the photo. I'll dig out some photos of the real thing and post them later.

Edit: Here also is a description and illustration of it - note the stem leaves:
