There are at least 40 species from about 20 genera that grow in disparate places around the world that have corkwood 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.
One of the sepcies is Hakea chordophylla, which is an Australian wood. Given the similarity of the woods shown below provided by Warrick Edmonds to other Australian woods, I hazard a guess that those woods below are probably Hakea chordophylla, but I wouldn't take bets on it.
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: all of the pics on this page were provided by Warrick Edmonds, who was kind enough to alert me to the existance of this wood. When he first sent me these, I thought it was lacewood by another name, but it is a separate species.
