the REST of the pictures on this page will give you a better overall feel for this wood
etimoe / Copaifera salikounda and Copaifera mildbraedii
of the family Fabaceae (syn Leguminosae) the legume, pea, or bean family
5" x 5" flat cut, 5" x 5" quartersawn, 1" wide end grain, and a 1/4" x 1/4" end grain closeup.
I do not know if the woods from the two species are distinguishable or not.
This is a West African wood, reportedly used primarily for rubber, but untapped trees are used to produce veneer and lumber. Also, in the USA at least, it is commonly called "African rosewood" although it is not a rosewood or even related to rosewoods. It can have a striking grain pattern and wonderful curly figure. There is also a form called "special etimoe" (yes, that actually is the name) that pretty much deserves the name simply because it doesn't look like any other wood at all (samples shown below).
I've had a lot of different eimoe veneers but have never seen it in plank form (other than the 6" long samples shown)
NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K)
colors will vary under other lighting conditions
