Can I just put in another request for these photos to come with a paragraph explaining a little more about what we're looking at?  This is lovely, but what's interesting about it?  I've read that the dawn redwood is believed to be more "evolutionarily old" -- that it has experienced fewer significant mutations since the Sequoioideae family first emerged.  Do its structures shed light on long-term adaptations of tree vascular systems?  For that matter, what are we really looking at?  What cell/tissue types are in the picture, and how have they been stained different colors?

Pretty, but what is the identity of the different classes of cell?

I support Auros' request for more information and have made a similar request previously.  If the picture is already published, what is the reference? Sometimes Google helps.
