| Populus alba
White poplarAlternate and simple, the leaves of this species are well known for their glossy dark green and glabrous upper surface and undersides that are covered with dense white pubescence. The leaves occur in two types, depending upon whether they are borne on long terminal shoots or short lateral shoots. Those borne on long shoots are broad ovate, 3 to 5-lobed, coarsely toothed and 2-5" long with entire margins. Although they may appear to resemble leaves of Acer campestre, the alternate leaf arrangement and pubescence easily differentiates them. Those borne on short shoots are smaller, ovate to elliptic-oblong and have sinuate-dentate margins. Like other poplars the petioles are flattened. |
