Two-leaf senna

Here’s a native wildflower I’ve never shown you before. That’s surprising, given that it grows in my neighborhood and that on several occasions I’ve shown the other species of senna that grows here. This one is Senna roemeriana, known as two-leaf senna or two-leaved senna. The common name refers to the fact that each of the plant’s leaves is made up of two leaflets; you can see one leaflet and part of its symmetric twin at the lower left in the photograph.

I took this picture beneath the power lines west of Morado Circle one month ago today.
