I was told that at least some of the plants at the NC Zoo exhibit were
introduced species seized from an experimental bog established without
permission on a US military reservation. So don't get excited if you should
see any collection site data that would indicate a new locality. I think
they may include _S. purpurea purpurea heteophylla_ and possibly _S. rubra
jonesii_ or _S. oreophila_.
Phil, which paper was that in?
