It didn't occur to me that I should see this plant while I was in southern Ohio--clearly an oversight on my part. I have always wondered about this plant, the mysterious other-violet-that-doesn't-look-like-a-violet. When I first saw this I thought it was Verbesina, but then I noticed the odd bulbous pod-thing, and a little lightbulb went off in my head:
"Oh, so that's Hybanthus. Hmm, cool."
Infrequent (insofar as I could tell) along forest margin near prairie.
Mahoe is common in the wooded gullies by the river. Here it has Cephaleuros lagerheimii on its leaves (added as a separate observation).
