Vascular bundle

[Dave Matthews]

Hi Katica,

I'm out of my league here, I'm no anatomist.  But I think a vascular bundle
is quite different from a vein.  Refers to a feature that's specific for
C4 plants.  Containing a cell type called bundle sheath cells that also
are found only in C4 plants.  Searching PubMed for "vascular bundle C4"
found some abstracts that might be worth peeking at.  E.g.
