Trees, deciduous. Bark grayish white, longitudinally fissured, falling off in small masses. Winter buds ovoid, surrounded by 2 connate stipules. Stipules free from petiole. Leaves spirally arranged, folded and pendulous in buds; petiole long; leaf blade with 1 or 2 lateral lobes near base, apex truncate to emarginate. Flowers terminal, solitary, bisexual, not fragrant, appearing at same time as leaves. Tepals 9, in 3 whorls, subequal. Anthers dehiscing extrorsely. Gynoecium sessile; carpels many, spirally arranged, distinct, basal ones sterile; ovules 2 per carpel, pendulous. Fruit fusiform; mature carpels woody, falling off from torus when matured; testa fused with endocarp, apex elongated winglike; torus persistent. Seeds 1 or 2 per carpel; testa thin and dry.
Trees , deciduous. Pith diaphragmed. Leaves distinctly alternate, not in false terminal whorl; stipules tardily deciduous on summer shoots, free. Leaf blade evenly (2-)4-6(-10)-lobed, base rounded to shallowly cordate or truncate, apex broadly truncate or notched; surfaces abaxially glaucous, adaxially lustrous, smooth. Flowers protogynous, appearing with the leaves; tepals (7-)9, petaloid, tip recurved, greenish yellow with feathered orange band or blotch near base, outermost tepals sepaloid, reflexed, green; stamens on short torus, tardily deciduous, whorled; filaments 1/3-1/2 length of extrorse anthers.
