There are at least 2 dozen species from a dozen genera that have bois de rose as all or part of one or more of their common names, and since the term simply means "wood that is red", I find it quite surprising that there are not dozens more.
HOWEVER, in the USA, it is generally used to mean Dalbergia maritima, which is one of the many Madagascar rosewoods. It is widely used by luthiers.
my samples: NOTE: these pics were all taken in very bright incandescent lighting ("soft white" at 2700K) colors will vary under other lighting conditions
