Glabrous with the exception of the hairs on the young leaves and 

 petioles. Leaves ovate to oval or rhombic, acuminate at the ends, or 

 acute at the apex and abruptly cuneate at the base, finely often 

 doubly serrate, with straight glandular teeth, and slightly divided 

 usually only above the middle into 3 or 4 pairs of small acute lobes 

 usually pointing toward the apex of the leaf; deeply tinged with red 

 when they unfold, not more than one-third grown when the flowers 

 open about the 20th of May and then dark yellow-green, smooth, 

 lustrous and slightly hairy above and pale and glabrous below, and at 

 maturity thin but firm in texture, dark yellow-green on the upper 

 surface, pale on the lower surface, 5-5.5 cm. long and 3.5-4 cm. wide, 

 with thin prominent midribs and primary veins; petioles slender, 

 narrowly wing-margined often to the middle, slightly villose on the 

 upper side while young, soon becoming glabrous, 2-3 cm. in length; 

 leaves on vigorous shoots broadly ovate, acute, rounded at the wide 

 base, coarsely sen ate, deeply lobed, and often 5-6 cm. long and broad, 

 with stout conspicuously glandular petioles. Flowers 1.8 cm. in 

 diameter, on long slender pedicels, in compact 3-6-flowered corymbs, 

 the elongated lower peduncles from the axils of upper leaves; calyx- 

 tube narrowly obconic, the lobes gradually narrowed from the base, 

 long, slender, acuminate, entire or occasionally minutely dentate 

 near the middle, reflexed after anthesis ; stamens 10-20 ; anthers cream 

 color, minute; styles 3 or 4. Fruit ripening the middle of September, 

 on stout drooping pedicels, in few-fruited clusters, subglobose to 

 slightly obovate, red, pruinose, 1.2-1.3 cm. in diameter; calyx little 

 enlarged, with a short neck, a deep narrow cavity pointed in the 

 bottom, and reflexed appressed persistent lobes dark red on the upper 

 side below the middle; flesh thin, firm, pale green; nutlets 3 or 4,
