Leaves oblong-ovate, acuminate, gradually narrowed and rounded 

 or broadly cuneate at the entire or crenulate base, sharply and doubly 

 serrate above, with straight gland-tipped teeth, and deeply divided 

 usually only above the middle into numerous narrow acuminate 

 spreading lobes; tinged with red and covered on the upper side with 

 short, rigid shining hairs when they unfold, and more than half grown 

 when the flowers open and then membranaceous, light yellow-green 

 and scabrate on the upper surface, and pale and glabrous on the lower 

 surface; at maturity thin but firm in texture, dark blue-green and 

 smooth above, pale bluish green below, 5-7 cm. long, 4-6 cm. wide, 

 with thin midribs and primary veins; petioles slender, grooved, 

 sparingly glandular, 4-6 cm. in length; stipules glandular, usually 

 caducous before the flowers open; on vigorous leading shoots, leaves 

 broadly ovate, cordate at the base, deeply divided into numerous 

 broad acuminate lateral lobes, often 8-10 cm. long and 7-8 cm. wide, 

 their stipules foliaceous, lunate, very coarsely serrate, early deciduous. 

 Flowers about 1.2 cm. in diameter on long very slender glabrous 

 pedicels, in wide many-flowered compound corymbs; bracts and 

 bractlets linear, glandular-serrate, usually deciduous before the flowers 

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

 entire or slightly crenulate on the margins, usually red at the apex, 

 reflexed after anthesis; stamens 10; anthers rose color; styles 2-4, 

 surrounded at the base by a ring of long pale hairs. Fruit on long 

 slender pedicels, in wide lax drooping showy many-fruited clusters, 

 oblong, full and rounded at, the ends, scarlet, lustrous, i. 2-1.4 cm. 

 long, 9-10 mm. broad; calyx sessile, with a narrow shallow cavity and 

 much enlarged, erect or slightly spreading lobes usually persistent on 

 the ripe fruit; flesh thin, yellow, dry and mealy; nutlets 2-4 broad, 

 rounded and obtuse at the ends, prominently ridged on the back, with 

 a high rounded ridge, 7 mm. in length.
