Deciduous tree, dioecious, up to 30 m in height, \u00b1 regular in shape; crown ovoid (cylindrical in some cultivated forms) with extended branches. Trunk straight up to 1.5 m in diameter, with a grey to blackish bark and highly fissured longitudinally from young; sometimes with the surface covered in numerous lumps and a large amount of regrowths born almost from the base. Branches glabrescent, first yellow and turning greenish-grey to light brown over the years. Buds with 4-6 scales, usually quite viscous, glabrescent. Leaves alternate, 4-10 \u00d7 4-8 cm, all similar in shape, ovate-rhomboid or ovate-triangular more often, the base a wide wedge, with crenate-dentate margin, resinous and sometimes somewhat pubescent at birth, then they quickly lose this viscosity and become glabrous, \u00b1 dark green on the upper side and slightly lighter green on the underside; long petioles. Flowers in cylindrical pendant aments, male aments 3-9 \u00d7 0.8-1.5 cm, sessile, slightly hairy; female aments 7-15 \u00d7 0,6-0,9 cm, with short peduncle. Flowers with persistent nectariferous disk; male flowers with 6-25(30) stamens with white filaments and purple anthers; female flowers with ovoid-conical ovary and 2 yellow stigmas. Fruit a small ellipsoid capsule about 8 mm, dehiscent into 2 valves that release numerous minute seeds, with long whitish hairs. These hairs (joined to the seeds) fall after remaining suspended in the air for some time, accumulating on the floor in characteristic cottony masses. 2n = 38.<\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-12201","species","type-species","status-publish","hentry"],"acf":[],"yoast_head":"\n
