longflower beeblossom, Oenothera filiformis

This small plant of longflower beeblossom was just finishing its season at Lynx Prairie Preserve. I shot it on spec, not knowing if it was longflower or biennial beeblossom. We now know this one has curly hairs on the stem, while biennial has straight ones. Otherwise the are a lot alike. Longflower grows in AL, AR, CO, CT, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, MS, NE, OH, OK, PA, TN, TX, WI, and ON. Adams Co OH, 10/2/21. Willowherb family, Onagraceae.
