Found this plant near the great wall. I want to do a project on it but I can't identify it.
It has ovate leaves and long thin seed pods.
A Legume, very likely. I would not be of much help with that family. Without a flower, I do think it will be very difficult to ID. Maybe someone who is very knowledgable in the flora of that area will know it. Perhaps post it on a Chinese site?
After browsing through tons of websites, the most similar I found is the Indigofera amblyantha.
