Glabrous. Leaves broadly ovate., acute or acuminate, abruptly 

 cuneate or rounded at the base, sharply doubly serrate with 

 straight glandular teeth, and divided into four or five pairs of 

 small acuminate lobes ; more than half-grown when the flowers 

 open in the first week of June and then thin, yellow-green, 

 smooth and lustrous on the upper surface, pale on the lower sur- 

 face, and at maturity 6 to 7 cm long and wide, with thin midribs 

 and primary veins ; petioles slender, narrowly wing-margined 

 nearly to the middle, rose colored in the autumn, 1.5 to 2 cm in 

 length ; leaves on vigorous shoots sometimes rounded at the 

 broad base, more coarsely serrate and more deeply lobed, often 

 8 cm long and wide, their petioles stout, glandular with persist- 

 ent glands, 2 to 2.5 cm in length. Flowers 2.5 to 2.8 cm in diam- 

 eter, on slender pedicels, in usually six- to eight-flowered 

 corymbs, the lower peduncles from the axils of upper leaves ; 

 calyx-tube broadly obconic, the lobes separated by wide sinuses, 

 broad, acuminate, coarsely glandular-serrate, reflexed after an- 

 thesis ; stamens twenty ; anthers pale pink ; styles four or five. 

 Fruit ripening in October on drooping pedicels, short-oblong, 

 rounded at the ends, vermilion, marked by occasional large pale 

 dots, 1 cm long and 8 to 9 mm in diameter ; calyx prominent with 

 a short tube, a broad deep cavity wide in the bottom, and spread- 

 ing and appressed lobes mostly deciduous from the ripe fruit; 

 nutlets four or five, acute at the ends, rather broader at the apex
