Hi all. I'm currently living in asia and found at least two Lespedeza that I would call different species. I believe the one in the first two pictures is L. bicolor. The other I'm not sure. There seems to be a lot of variability in leaf size and shape on plants that are right next to each other and even on the same plant. Its hard to identify without a good book in english.

There hasn't been too much research on this plant from what I've seen. I read one post on Edot in which the poster concluding his collection of bicolor was inactive.

I'm willing to donate some material for anyone that can perform a TLC analysis
