More spring bulbs.

When I decided to get spring bulbs I went a little crazy (i.e. bought many, many different types). Some of them are still around while others never even broke the soil. Part of the decision making was to buy "species" bulbs and not horticultural varieties. This is a Fritillaria species. Which one? I have no clue. I should have written down names, put tags in the garden, or some combination of the two. I didn't, and now the information is lost forever. Only because I'm too busy/lazy to figure it out...
