Bermuda? St Augustine? Rye? There are lots of types of "grass". <img src="/images/graemlins/smile.gif" alt="" /> I feel your pain. Learning to identify useful wild and introduced plant life in my area with extreme accuracy has been a project of mine for about a year now and I still have a loooooooooong way to go! I have yet to find any really good (free) info on the web but I have found several good field guides on Amazon.com after sifting through a sea of useless ones. Most of the ones I have are regional and focused on my area although I do have one that I really like that covers the entire lower 48. If I'm not 100% sure then I don't eat it. I mostly stick with the really easy stuff right now and I do eat things like Sunflower seeds and Cattail bulbs often.
