Xylia spp. of the family Fabaceae (syn Leguminosae) the legume, pea, or bean family, including at least Xylia dolabriformis and Xylia xylocarpa
This is a very hard wood from the Burma/Thailand region and it also is one of the many worldwide woods that goes by the name of "ironwood" among other common names.
my samples: NOTE: these pics were all taken in very bright incandescent lighting --- colors will vary under other lighting conditions
both sides of a sample plank of pyinkado / Xylia dolabriformis --- HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site. The labeled side is raw but the 2nd side has been sanded down to 240 grit so looks a bit richer in color and shows the face grain details a little better. NOTE: this is a laminated sample with two thin pieces one on top of the other.
