There are at least a dozen species from over two dozen genera that have kapur as all or part of one or more of their common names, and I have no idea which of them are represented on this page.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
