Leaves oblong-ovate, acuminate, broad and roinided or gradually 

 narrowed and cuneate at the base, finely doubly serrate, with straight 

 glandular teeth, and divided into 5-8 pairs of widespreading often 

 incurved acuminate lateral lobes; nearly half grown when the flow- 

 ers open about the 25th of May and then thin, yellow-green and 

 roughened above by short white hairs and pale and glabrous below, 

 and at maturity thin but firm in texture, bright yellow-green, smooth 

 and lustrous on the upper surface and pale and glaucous on the 

 lower surface, 4.5-7 cm long and 4-5.5 cm wide, with stout midribs 

 and slender primary veins arching obliquely to the points of the 

 lobes ; petioles slender, slightly wing-margined at the apex, glandu- 

 lar, with minute persistent glands, 2-3 cm in length ; leaves on vig- 

 orous shoots thin, rounded or slightly cordate at the base, more 

 deeply lobed, often 6-7 cm long and 5-6 cm wide. Flowers 

 1. 5-1. 6 cm in diameter, on long slender glabrous pedicels, in wide 

 lax, mostly 8-io-flowered corymbs, the lower peduncles from the 

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

 lobes abruptly narrowed from broad bases, slender, acuminate, 

 entire or occasionally obscurely dentate, glabrous, reddish, reflexed 

 after anthesis ; stamens 10; anthers pink; styles 3 or 4, surrounded 

 at the base by a narrow ring of matted pale hairs. Fruit ripening

 of the leaves, on slender reddish pedicels, in few-fruited drooping 

 clusters, short-oblong or slightly obovate, somewhat angled, bright 

 orange-red, lustrous, marked by numerous small pale dots,
