Handbook of the Trees of New England 6.0分: Henry M. (Henry Mason) BrooksLorin Low Dame; "There is no lack of good manuals of botany in this country. There still seems place for an adequately illustrated book of convenient size for field use. The larger manuals, moreover, cover extensive regions and sometimes fail by reason of their universality to give a definite idea of plants as they grow within more limited areas. New England marks a meeting place of the Canadian and Alleghanian floras. Many southern plants, long after they have abandoned more elevated situations northward, continue to advance up the valleys of the Connecticut and Merrimac rivers, in which they ultimately disappear entirely or else reappear in the valley of the St. Lawrence while many northern plants pushing southward maintain a more or less precarious existence upon the mountain summits or in the cold swamps of New England, and sometimes follow along the mountain ridges to the middle or southern states."; 外国经典
