Deleting remote branches

Hi,

I had a whole bunch of branches in my local and a remote repository. I
deleted all the redundant branches to be left with only three now. So the
result of $git branch on my local repository is
[pradeep@scaramanga cffc]$ git branch
  jeff
  master
* work
and on the remote directory which is called 'origin' it returns
[pradeep@scaramanga CFFC.git]$ git branch
  RANSmodel
* master
  work
But when I type the following command on my local branch, 
[pradeep@scaramanga cffc]$ git branch -a
  jeff
  master
* work
  origin/HEAD
  origin/RANSmodel
  origin/bluffbody
  origin/counterflow
  origin/flamelet
  origin/jeff
  origin/master
  origin/test
  origin/work
I still get all these branches which I deleted in my remote 'origin'.

My .git/config file looks like this
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = /nfs/carv/d1/people/pradeep/Repositories/CFFC.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[remote "jeff"]
        url = /nfs/kris/d1/people/jeff/cffc
        fetch = +refs/heads/pradeep:refs/remotes/jeff/pradeep
[branch "master"]
        remote = origin
        merge = refs/heads/master
[branch "work"]
        remote = origin
        merge = refs/heads/work
[push]
        default = matching
[branch "jeff"]
        remote = jeff
        merge = refs/heads/pradeep

Does anyone know why am I still getting branhces like origin/test when I do $git branch -a
