Possible in the family Desidae, but I'm not sure. Plenty of these in the amaryllis (?) in the median outside of Cheeseboard. Somewhat tangled, ladder-like webs, with retreats. I collected it for my spider biology class.

Update: Turns out it was a desid, and there's only one in the area. Noice! Also, I think there's a spelling error in my spider manual...
