That's a completely reasonable question Moby and has me thinking
I have found no information that this species of Bauhinia is used for timber.
(However other Bauhinia species have been used for turning.)
The grain looks similar to Cooktown Ironwood
It can be polished just by burnishing or with 400 sandpaper
Its heavy like ironwood
I weighed a 100mm wet cube at 1390g today - I might have to microwave this
On the other hand, there are no other ironwood trees anywhere near where this tree had burnt down. No lignotubers of ironwood near by. Every other burnt Ironwood I have come across has new growth from these
The sapwood and the bark are different. There are no horns on the back of the bark
It smells different
I did take a sample of the dried leaves which matched the "mother inlaw" (looking opposite directions) morphology but I will return to the crown of the tree to look again at the leaf formation.
I could only find some random unreferenced UK claim that this species is the heaviest in the world.
See fact 9. h
