Trees are the glory of the American landscape. A text of impeccable authority, drawings of matchless precision and delicacy, and fine photographs combine to make this beautiful edition an indispensable guide and valued possession. Pennsylvania, "Penn's Woods," is the meeting place of America's southern and northern tree flora: magnolia and hemlock, Spanish oak and yellow birch flourish alike. This extraordinarily complete handbook covers all trees native to the state and most naturalized species.
