Some NOIDs from the trip a couple days ago to Kent State Park, including a reposting of a couple from the Yellow post on Tuesday. Slightly more detail may be available if opened in another window:
#2: The one that's been driving me crazy in the last few weeks. (Identified in comments by J as Chamaecrista fasciculata, partridge pea. It was probably deliberately planted by the state.)
#3: Blue thing. (Identified in comments by J as Campanula americana.)
#3: Another shot of the blue thing.
#4: Strange orangish flower. (Identified in comments by J as Impatiens capensis)
#5: Vine with red-purple flowers. This one's scary: I saw it strangling a thistle, for chrissakes. It also seems really familiar to me, but I can't place it. (Identified in comments by J as Apios americana, American groundnut.)
#6: Not a good picture, I'm aware. I'm not really expecting an ID. Just point me in a direction.
Anybody have any guesses?
