Bob,
I think the reason I had the wrong photo was when I did a search for Zigadenus Leimanthoides the site that came up with that photo also had the Zigadenus nuttallii with it. That is actually what the plant is in the photo I sent you according to this site. They call it a Death Camus or Poison Onion.

Ahh, the mystery continues. I did not think it was anything but fly poison since they look familiar. Maybe yours is an even better match. Here is the fly poison. In the past they would crush the bulb and if a fly landed and used it for some nefarious reason, it keeled over and died.
