Leaves obovate or obovate-cuneiform, acute or sometimes rounded and frequently

 from above the middle to the entire base, and serrate or doubly serrate above, with 

 incurved conspicuously glandular teeth, when they unfold often dark red, covered 

 above with long pale caducous hairs and villose below along the midribs and veins, 

 nearly fully grown when the flowers open from the 1st to the 10th of May and then 

 bright yellow-green and almost glabrous with the exception of the persistent tufts 

 of pale hairs in the axils of the veins, and at maturity thin but firm in texture, dark 

 green and lustrous above, paler below, usually about 1^' long and 1' wide, with

 obliquely to the points of the lobes, and dark conspicuous reticulate veinlets, turning 

 red, yellow, or brown in the autumn; th^ir petioles slender, glandular, wing-margined 

 above, at first tomentose, becoming pubescent or nearly glabrous, about -I' long; on

 rounded or acute lobes, 2'-2y in diameter, their stipules lunate, coarsely glandular- 

 dentate, sometimes ^' long. Flowers |' in diameter, on slender elongated pedicels
