Tom - my picture is not typical of the veining on Acoma. If you see my database clump, they are much less pronounced. And I did bring out the beard fact.
Joe - is there purple in the foliage at the base of the plant? That will help tell if it is or isn't Acoma. I can't really tell if all the beards are all yellow in your clump shot. Can you check your blooms. If the beard is all yellow on all the blooms it definitely isn't Acoma.
Sure is a close cousin though.
