A deciduous tree 30 ft high; young shoots quite glabrous, pale bright green at first, becoming striped with pale lines later; buds stalked. Leaves of papery texture, mostly three-lobed, sometimes obscurely five-lobed, sometimes not lobed at all and merely ovate, doubly and rather jaggedly toothed, more or less heart-shaped at the base, the short points of the lobes pointing forward; 21⁄2 to 6 in. long, from two-thirds to fully as much wide; dull green above, pale beneath, glabrous on both surfaces; stalk 11⁄2 to 31⁄2 in. long. Flowers in drooping racemes 3 to 4 in. long. Wings of the fruit together with the nutlet 3⁄4 to 1 in. long, glabrous, spreading almost horizontally; each fruit on a slender stalk up to 3⁄8 in. long.
Native of Manchuria and Korea. According to Nicholson it was cultivated by Lavallée at Segrez in France in the seventies of last century. It has always been rare and there is no record of any large specimen; the best at Kew is 8 ft high. It belongs to the same group as A. capillipes and A. rufinerve; the latter is easily distinguished by the reddish down along the veins of the leaf beneath. In A. capillipes the young shoots and leaves are reddish and the fruit stalks longer.
