Andira inermis of the family Fabaceae. There are also several species from the genus Caesalpinia that have partridgewood as all or part of one or more of their common names and to add to the possible confusion, an unrelated wood, Millettia stuhlmannii which is more properly called panga panga, is also sometimes sold in the US (but apparently not in Great Britain) as partridgewood.
NOTE For a long time I marked all my panga panga as partridgewood, due to my confusion about what wood was what. This includes segments in my bowls, so if you have one of my bowls and the wood was, and possibly still is, listed on the bowl's web page as partridgewood, it is panga panga. The difference between the species is unmistakeable, I just had the common names confused. That is, I correctly identified the wood as Millettia stuhlmannii but gave the common name incorrectly as partridgewood.
I have never seen this wood, and have no great confidence that what is on this page is Andira inermis but I believe that to be more likely than the Caesalpinia species.
