This wood was sold to me under the common name itannin, but I cannot find that name in any reference and I have no clue what species it is. The only other image I could find was copied from this page, so no help there.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
two turning sticks
end grain of the pices directly above
end grain closeups of the pieces directly above --- the pics are too gray, should be more brown
