Yummy, I don't know if Central texas isaprpriate but I will try. I will be out collecting Muhlenbergia seeds tomorrow for myself and Texas ranger. I found a population that is not quiet M. Lindheimeri and not quite M. riverchoni . I don't know if they are a local variation or an environment al effect, but they are very different from what I know as M. lindheimeri. You can get a hold of me through the email on my page and I will try through yours.
