Thermopsis divaricarpa (Golden Banner)
Family: Fabaceae (Pea)
     
Thermopsis divaricarpa has spreading, slightly curved seed pods. In flower, this species looks very similar to Thermopsis rhombifolia and Thermopsis montana (not pictured). The species are identified by the shape of their seed pods. T. rhombifolia has strongly curved pods and T. montana has straight, erect pods. Some sources consider all three to be varieties of a single species. Weber describes T. divaricarpa as having glabrous seed pods, but the pods in the photo are strongly pubescent, suggesting this might not be a good identifying characteristic.
