A descriptive guide that examines the winter characteristics of deciduous trees of northeastern America. It begins with general winter morphology—trunks, branches, twigs, buds, and leaf- and bundle-scars—then offers species-by-species accounts organized by familiar groups (maples, oaks, birches, ashes, walnuts, and others), emphasizing identification features visible in leafless seasons. Entries are illustrated with colored plates and photographs and note trunk, bud, and twig traits to aid recognition and close study during winter months.
