Leaves ovate, acuminate, rounded or cuneate at the base, sharply 

 and often doubly serrate above, with straight glandular teeth, and 

 divided into four or five pairs of small acuminate spreading lobes, 

 when they unfold deeply tinged with red and coated above with long 

 white hairs, about half grown when the flowers open the middle of 

 May and then thin, yellowish green, scabrate and slightly hairy 

 above along the midribs and pale and sparingly villose along the 

 midribs and veins below, at maturity thin, yellow green and rough 

 on the upper, pale and nearly glabrous on the lower surface, 6-7 cm 

 long, 5-6 cm wide, with stout orange colored midribs, and slender 

 primary veins extending obliquely to the points of the lobes; 

 petioles slender, nearly terete, glandular toward the apex, slightly 

 villose through the season, often tinged with rose color, 2-2.5 cm m 

 length; leaves on vigorous shoots broadly ovate, long pointed, 

 truncate or slightly cordate at the base, coarsely serrate and more 

 deeply lobed. Flowers about 1.5 cm in diameter, on short stout 

 villose-pubescent pedicels, in very compact, hairy, usually 8 to 10- 

 flowered corymbs, with oblong to linear acute glandular bracts and 

 bractlets fading brown and mostly deciduous before the flowers 

 open; calyx tube narrowly obconic, glabrous, the lobes slender, 

 gradually narrowed, long-pointed and acuminate, glandular serrate, 

 glabrous on the outer, villose on the inner surface, reflexed after 

 anthesis; stamens 7 to 10; anthers rose color; styles three or four. 

 Fruit ripening about the middle of September, on short stout 

 slightly hairy pedicels, in few-fruited clusters, subglobose to oval, 

 crimson, lustrous, marked by numerous pale dots, 1.3-1.5 cm in 

 diameter; calyx little enlarged, with a wide shallow cavity, and 

 slender spreading closely appressed glandular serrate lobes slightly 

 hairy on the upper side and mostly persistent on the ripe fruit; 

 flesh thin, yellow, dry and mealy; nutlets three or four, narrowed 

 and rounded at the ends, irregularly ridged on the back, with a 

 broad low grooved ridge, 6-7 mm long and 4-5 mm wide. 



A shrub or small tree 4-5 m high, with slender nearly straight 

 branchlets marked by small pale lenticels, dark orange-green and 

 glabrous when they first appear, becoming bright chestnut-brown
