We've seeded our dryland pasture with a basic dryland mix from the Co-op.  Although I have a list of the grasses included in the mix, I can't identify by sight which is which.  The accompanying picture shows what we seem to have the most of and, naturally, it's the kind of grass the horses are not at all interested in.  Can someone tell me what kind of grass this is so that we can look for a mix that has a lower content of it next time we seed?
