For me the baffling thing about this tree is that the leaves occur in groups of four to seven individual leaves each of which is attached by a thin and very flexible rhubarb-red stalk to a short spur or node formed at a random angular position along a branch. Each leaf group forms a whorl around its spur, Whatever the angular position of the spur the stalks are long enough to allow all of the leave blades to hang tip down below the branch which carries them. There's no useful evidence of flowers or fruit. Young tree about 120 mm diameter, maybe 4 metres high and still in its wire cage. Help!
