Madagascar has numerous rosewood species, and three are pretty common. The most commonly compared to Braz is palisander, a madagascar rosewood that looks nearly identical to Braz rose & is about the same weight/density with similar tonal characteristics. It is not bois de rose but is also a madagascar rosewood.
Many of the east African & Asian areas have countless rosewood species & sub-species. Look at East Indian rosewood. It's all sold as EIR but there are numerous types, the most common being the deep purple stuff. I have some that is nearly identical to bois de rose, except came from India, which is only approx. 300 miles from Madagascar. In SE Asia, each island has it's own twist of rosewoods. Of all the different rosewoods that come from central & south America, why would the other side of the pond be any different? We as cuemakers only know the most commonly commercial cut lumbers, but there are many, many more lesser known species than we see in the market. All are great cue woods.
