Glabrous with the exception of the hairs on the young leaves 

 and calyx-lobes. Leaves ovate to oval, long-pointed and acuminate 

 at the apex, cuneate at the entire base, finely often doubly serrate 

 above, with straight glandular teeth and slightly divided into 

 4 or 5 pairs of small acuminate lobes ; more than half -grown when 

 the flowers open early in June and then yellow green, smooth and 

 furnished with a few hairs on the midribs above, and pale below, 

 and at maturity thick, bluish green, paler on the lower surface 

 than on the upper surface, 4.5-6 cm long and 3-5 cm wide, with 

 thin midribs and primary veins ; petioles slender, narrowly wing- 

 margined at the apex, slightly hairy on the upper side early in the 

 season, soon becoming glabrous, 1-1.2 cm in length; leaves on 

 vigorous shoots broadly ovate to slightly obovate, rounded or 

 cuneate at the base, more coarsely serrate, conspicuously lobed, and 

 often 7-8 cm long and 5.5-6 cm wide, with stout rose-colored 

 midribs and petioles. Flowers 1.8-2 cm in diameter, on long 

 slender pedicels, in 6-15-flowered corymbs, the lower peduncles 

 from the axils of upper leaves ; calyx-tube narrowly obconic, the 

 lobes gradually contracted from the base, short, broad, acuminate, 

 glandular-serrate near the middle, slightly hairy on the inner sur- 

 face, reflexed after anthesis ; stamens 20; filaments persistent on 

 the fruit; anthers pink; styles 3 or 4. Fruit ripening early in 

 October, on long slender drooping pedicels, in few-fruited clus- 

 ters, subglobose, slightly 5-angled, pruinose, bright red, marked by 

 occasional pale dots, about i cm in diameter ; calyx promineni 

 with a long tube, a deep broad cavity wide and tomentose in the bot- 

 tom, and spreading and reflexed lobes ; flesh thick, yellow, dry and 

 mealy; nutlets 3-5, narrowed and rounded at the apex, broader
