Chinodoxia, Scilla and Puschkinia, aka Squill, closely resemble one another. I'm not expert on the differences, so please forgive me if I have mislabeled the images in this floral group. I will try to make corrections as I learn more about these plants.
Chinodoxia appears to resemble "Squill" or Scilla, but is not a member of the lily family. See http://pbase.com/hjsteed/squill_or_scilla for more information & photos of that lily group.
