Glabrous. Leaves broadly ovate, acute or acuminate, abruptly 

 cuneate or rounded at the broad base, sharply often doubly serrate, 

 with straight glandular teeth, and slightly divided usually only above 

 the middle into 3 or 4 pairs of small acuminate spreading lobes ; tinged 

 with red when they first appear, more than half grown when the 

 flowers open from the 15th to the 20th of May and then thin, light 

 yellow-green and lustrous above and paler below, and at maturity 

 thick, dark yellow-green on the upper surface, paler and bluish green 

 on the lower surface, 5-7 cm. long and 4-5.5 cm. wide, with thin mid- 

 ribs and primary veins; petioles slender, 2.5-3.5 cm. in length; leaves 

 on vigorous shoots broadly ovate, acuminate, cordate or occasionally 

 truncate at the base, more coarsely serrate and more deeply lobed, 

 and often 5-6 cm. long and wide. Flowers 2.4-2.5 cm. in diameter, 

 on slender pedicels, in mostly 5-7-flowered compact corymbs, with 

 obovate to linear glandular bracts and bractlets fading rose color and 

 often persistent until the flowers open, the lower peduncles from the 

 axils of upper leaves; calyx-tube broadly obconic, the lobes gradually 

 narrowed from broad bases, long, acuminate, entire or occasionally 

 minutely dentate near the middle, reflexed after anthesis; stamens 20; 

 anthers white; styles 4 or 5, surrounded at the base by a narrow ring 

 of white hairs. Fruit ripening late in October and often persistent 

 until after the leaves have fallen, on short stout erect or spreading 

 pedicels, in few-fruited clusters, subglobose, sometimes rather broader 

 than high, dull red blotched with green, slightly pruinose, 1.2-1.3 cm. 

 in diameter; calyx much enlarged, with a short tube, a broad deep 

 cavity wide and tomentose in the bottom, and spreading and reflexed 

 persistent lobes; flesh thin, green, dry and mealy; nutlets 4 or 5, 

 narrowed at the ends, broader at the apex than at the base, rounded 

 and slightly grooved on the back, 6.5-7 mm. long and about 4 mm. 

 wide. 



A shrub 2-3 m. high, with numerous stems, and slender nearly 

 straight branchlets dark green more or less tinged with red when 

 they first appear, becoming dark chestnut brown, lustrous and marked 

 by pale lenticels in their first season, darker-colored the following 

 year, and armed with numerous slender straight or slightly curved 

 purple shining spines 3-4 cm. in length.
