Bois de Rose is used to describe many different kinds of Rosewood. When I see it used in descriptions of cues, it is referring to Madagascar Rosewood [Dalbergia Baroni].
With all due respect, but Bois de Rose is actually Dalbergia Maritima. It is a subspecies of Madagascar Rosewood, in that it is only found on the island of Madagascar...which is no longer legally exporting any of their species of wood, as it is now considered endangered. There are approximately 47 species of rosewood found on the island of Madagascar.
The French translation for Tulipwood is called Bois de Rose. Tulipwood is Dalbergia Frutescans, and is generally found in Brazil and Burma. Both Bois de Rose and Tulipwood are what are considered 'true' rosewoods...as the rosewood family is quite varied...lots of 'kissing cousins'.
What both BdR and Tulip have in common is that they are both very 'wet' woods, and can take quite some time (years) to season properly. If not seasoned properly, they are prone to movement. I am told that both smell wonderful when cutting, however, many makers will not use BdR as it does tend to 'bleed' like a stuck pig, and can stain other, lighter colored woods if proper care is not taken.
I may well have one of the only full spliced BdR cues in existence, and into a BEM nose, the cue plays like a dream. I am told that with regards to playability, it is very close to that of the dark Brazilian Rosewood of old. It has a ton of resonance to it, translating into terrific feedback throughout the length of the cue. I cannot wait until my Tulip/BEM full splice is completed, so that I can compare the two 'hits' side-by-side.
