Matt, if you are interested I can put you in contact with somebody who can give you an definite ID with this set of photos. He is currently teaching me how to ID these grasses.
All I can say is thank you for NatureMapping MattM & all of you moderators for taking the time to get in to tiny details that are beyond us volunteers at Friends of Flea Bog Flat, thnx!!
I put it through Vicflora & got R.caespitosum as well Matt. It looks pretty good to me, similar to R.fulvum but the seed shape appears to be a bit different.
