Leaves obovate-cuneate, frequently 3-lobed at the apex, with short rounded lobes, 

 gradually narrowed and cuneate at the entire base, finely serrate above, with straight 

 or incurved teeth tipped with showy ultimately dark persistent glands, 3-nerved, 

 with slender nerves, and numerous thin secondary veins and reticulate veinlets, 

 slightly villose above as they unfold, nearly fully grown when the flowers open about 

 the middle of March, and then light yellow-green and glabrous with the exception of 

 a few persistent hairs along the upper side of the nerves and in their axils, and at 

 maturity thick and firm, dark green and lustrous on the upper surface, pale on the 

 lower surface, V-l^' long and about ^ wide; their petioles slender, glandular, more 

 or less winged toward the apex, tomentose, becoming pubescent or glabrous, usually 

 about ^' long; on vigorous shoots frequently 2' long, and sometimes divided by deep 

 rounded sinuses into numerous narrow lateral lobes, their stipules lunate, foliaceous, 

 pointed, coarsely glandular-serrate. Flowers about I' in diameter, on slender tomen- 

 tose pedicels, in few usually 3-flowered simple compact corymbs; calyx-tube broadly 

 obconic, coated with long matted white hairs, the lobes narrow, acuminate, glandular, 

 with bright red stipitate glands, villose toward the base on the outer surface, and on 

 the inner surface; stamens 20; anthers small, pale yellow; styles 4 or 5, surrounded
