Deleting branches

Hi,
I wanted to see the all the branches of a remote repository and so in my
.git/config file I had something like
[remote "jeff"]
        url = /nfs/kris/d1/people/jeff/cffc
        fetch = +refs/heads/*:refs/remotes/jeff/*

But then I decided that I only need to see one particular_branch and I
changed it to
[remote "jeff"]
        url = /nfs/kris/d1/people/jeff/cffc
        fetch =
+refs/heads/particular_branch:refs/remotes/jeff/particular_branch

But even now, when I do a $git branch -a, I see this
[pradeep@scaramanga cffc]$ git branch -a
  jeff
  master
* work
  jeff/local
  jeff/master
  jeff/particular_branch
  origin/HEAD
  origin/master
  origin/work

Why am I still getting the other jeff branches in my list and how do I delete them? THanks
