It never occurred to me before, but today I have made up a trial inner rim 
using laminations of three-ply birch, a wood visually and structurally 
quite similar to maple.  If I were shown this without knowing its 
composition and without looking extremely closely, I would almost certainly 
say the laminations were of birch-or-maple and mahogany or some similar 
wood, so much does the end grain of the birch resemble mahogany in 
color.  I wonder if this is really the answer to the question after all.
