Trees and shrubs : an abridgment of the Arboretum et fruticetum britannicum : containing the hardy trees and schrubs of Britain, native and foreign, scientifically and popularly described : with their propagation, culture and uses and engravings of nearly all the species. Trees; Shrubs; Forests and forestry. 1Q00< F, canad^sis. Spec. Char., Sjc. Young branches angled. Petiole compressed. Disk of leaf roundish ovate, deltoid, acuminate, subcordate at the base, where there are glands, serrated with unequal teeth, glabrous. The branches are angular, and the angles form whitish lines, which persist even in the adult age of the tree. The trunk is furrowed, even in old age ; less so than that of P. an- gulata, more so than that of P. monilifera. The young buds are gummy. The catkins of the female are from 6 in. to 8 in. long. (jMcAx.) A large tree. North America, in high rocky places between Canada and Virginia, and about the western lakes. Height 70 ft. to 80 ft. Introduced in 1769. F lowers red ; April and May. Seeds ripe in June. Decaying leaves yellow. In Britain, the Canadian poplar used to be very commonly propagated in nurseries, and extensively introduced into plantations ; but, within the last SOyears,the black , Italian poplar (P. monilifera) has been substituted for it. Bosc says that the Canadian poplarapproaches nearer to P. nigra 1 ^ than any other L^ species ; and Mi- \ chaux, in 1840, expressed to us the same opinion, and in short that 1499. p. {n.) canadinsis. it WaS -dif&Cult tO distinguish them. Propagated by cuttings of the young wood, about 18 in. long, put in during autumn. The first shoots produced from these cuttings are always curved at the lower extremity, though in a few years this curvature entirely disap- pears. The same thing takes place with the cuttings of P. monilifera. "f 9. P. (? N.) iETULiFol-iA PuTsh. The Birch-leaved Poplar. Ideniificaiion. Pursh Fl. Amer. Sept., 2. p. 619.; Spreng. Syst.
