I do not know this variety, it has a very beautiful bark, on the other hand, I find the pot a little small !!!
The most popular Brazilian Rain Tree variation is the "Tortum" indeed, and it's beautiful on it's own way, the smooth, exfoliating bark has a nice contrast with the "Tenuiflorum", Tortum also has a bit smaller leaf, with more rounded tips, as the trunk and branches gets older it gets nice tortuous aspect (that gives it's name), like it's dented.
They're both wonderfull trees, but the Tenuiflorum it's more recent between Bonsai artists around here.
