II, Cottonwood Poplars with Excurrent Trunks. The general effect of the branching depends much upon the angle which each branch or twig forms with that one from which it springs. The angle may be quite acute, as in the birch ; or more nearly a right angle, as in the ash, Fig. 24. It is these differences that help to give to leafless woods in winter their unending variety and beauty. 64. Indefinite Annual Growth. — In most of the forest trees, and in the larger shrubs, the wood of the branches is matured and fully developed during the summer, and pro-.
