None of those branches are there, they are just your local mirrors. Run:

$ git remote prune origin

Unfortunately (or maybe fortunately) git doesn't do that automatically. It doesn't even indicate such branches anyhow. So you need to run that command periodically (once you want to get rid of the cruft), possibly adding "-n" option to see what would be pruned.
