The seibo, a middle-sized tree, adorned with violet-coloured leaves,
consists of crooked boughs, and a spungy wood, as soft as that of the
cork tree, so that, when fresh, it may be cut with a knife like an
apple; but after it is dry, axes are not sufficient to hew it. A bough
of this tree fixed in the ground takes root, and grows immediately.
Whenever the tiger feels his claws burn, he is said to rub them against
the bark of this tree to relieve the pain.
