Entandrophragma spp. of the family Meliaceae, the mahogany family, this wood is most often E. angolense but may also include any of the follwing (and possibly more I am not aware of): E. acuminata, E. delevoyi, E. dolicarpum, E. ferrugineum, E. leplaei, E. rederi, and E. rufa
This tropical African wood is a loosely mahogany-related (it's in the same family, but not any of the genera that contain the woods normally meant by the name "mahogany") and you can definitely see some similarities
my samples:
plank and end grain --- the lighter corner is sapwood which as you can see is easily distinguishable from the heartwood, but not sharply demarcated.
end grain closeup of the piece directly above --- although all of my own solid wood samples were purchased from the same vendor, this piece seems to have a significantly different end grain than the others and since the vendor in question is totally indifferent to the proper identification of wood, this might be a different species.
plank and end grain --- I'm not sure but I think this entire piece is probably sapwood

planks cut from a larger one (not the same as the other samples on this page) and a side pic of same
end grain closeups of the pieces directly above
veneer with very accurate color --- there is a heavy ribbon stripe to this veneer that hardly shows up at all in this pic or the one directly below

unsurfaced plank with the kind of brownish-rust colored patina that is found on MANY unfinished woods that have been exposed to the air for a while.
veneer
veneer listed as both "tiama mahogany" and "tropical mahogany" and I am not sure that it is the wood that is supposed to be on this page.
