I would be interested in reading such a discussion, or at least, a 
compilation, as last month I tried to differentiate several Cornus 
mas and a tree labelled Cornus officinalis 'Issai Minari' . Leaves, 
bark, and fruit all looked the same, except fruit was a bit later on 
the officinalis than on the mas.  I took a magnifier to search the 
underside of leaf veins for little clumps of hairs that C. 
officinalis is supposed to have, but couldn't see them on our tree.
