Leaves opposite, odd-pinnate. Flowers diœcious; so only a portion of the trees bear the small, odoriferous, 5-seeded, drupe-like fruit.

P. Amurénse.

Phellodéndron Amurénse. (Chinese Cork-Tree.) Leaves opposite, odd-pinnate, 1½ to 3 ft. long; leaflets 9 to many, lanceolate, sharply serrate, long-acuminate. Flowers inconspicuous, diœcious, in loose-spreading clusters at the ends of the branches. The pistillate flowers form small, black, pea-shaped fruit, in loose, grape-like clusters, thickly covered with glands containing a bitter, aromatic oil, and remaining on the tree in winter. Medium-sized tree (20 to 40 ft.), with Ailanthus-like leaves which turn bright red in autumn, and remain long on the tree. Hardy as far north as central Massachusetts.
