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 except as specifically noted.
Some of the species are in the genus Hakea. These include
Hakea chordophylla
Hakea divaricata
Hakea ivoryi
I think it likely that these are all Australian woods but I do not know that for sure.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
both sides of a sample plank of needlewood (=corkwood)/ Hakea ivoryi --- HUGE enlargements are present. This sample was contributed by Eric Krum whom I thank for this and other contributions to the site. Eric has the wood as needlewood, which is another common name for Hakea ivoryi.

END GRAIN UPDATE from directly above. In the enlargements, it is particularly obvious that this species has scalariform parenchyma.
both sides of a sample plank of needlewood (=corkwood)/ Hakea ivoryi --- HUGE enlargements are present. This sample was loaned to me by Mark Peet whom I thank for this and other contributions to the site. Mark got this from Eric Krum and it's probably from the same plank as the piece directly above.

In addition to contributing the samples directly above to me and to Mark, Eric also sent along these pics of a chunk and a couple of made objects:
needlewood / Hakea ivory chunk, turned box, and bottle stopper
NOTE: all of the pics below were provided by Warrick Edmonds, who was kind enough to alert me to the existence of this wood. When he first sent me these, I thought it was lacewood by another name, but it is a separate species.
