So far I think Geum aleppicum avens is the closest. The distribution maps do not show it in Texas and I have not yet found an image that is a perfect match in my opinion.
I have always wondered what this plant is since we bought this property over 20 years ago, but it has recently become more critical as it is the only unidentified plant growing plentifully in a pasture in which the horses have been diagnosed with liver damage. I really want to know whether it could be the cause. Thank you all for your efforts!
