Includes at least Calophyllum brasiliense, Calophyllum lucidum, and Calophyllum calaba of the family Guttiferae
I believe this wood is sometimes confused with bintangor, which is a different set of species in the same genus. Both sets of species are sometimes given both common names.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
NOTE: I had not previously experienced this wood at all and had at the time only one web pic to represent it, when Glen Smith sent me these two planks to help him identify the wood. I could not (I thought it was probably a member of the meranti group, but was not sure at all) and subsequently sent half of one of these planks to the USDA Center for Wood Anatomy Research, where it was identified as jacareuba.
