Glabrous with the exception of the hairs on the upper surface 

 of the young leaves. Leaves broadly ovate to obovate, acute or 

 acuminate, gradually narrowed and concave-cuneate at the entire base, 

 sharply often doubly serrate above, with straight glandular teeth, 

 and divided usually only above the middle into 4 or 5 pairs of small 

 acute spreading lobes; deeply tinged with red and covered above by 

 long white hairs when they unfold, nearly one-third grown when the 

 flowers open about the 20th of May and then dark yellow-green and 

 roughened above by short hairs and pale bluish green below, and at 

 maturity thin, yellow-green, scabrate on the upper surface, 5-6 cm. 

 long and 4.5-5.5 cm. wide, with thin prominent midribs and primary 

 veins; petioles stout, narrowly wing-margined sometimes to the 

 middle, glandular, with occasional minute persistent glands, 2-2.5 cm. 

 in length ; leaves on vigorous shoots ovate, rounded or abruptly 

 cuneate at the broad base, coarsely serrate, more deeply lobed, and often 

 6-7 cm. long and wide. Floicers 1.5 or 1.6 cm. in diameter, on long 

 stout pedicels, in compact mostly 5-7-flowered corymbs, the elongated 

 lower peduncles from the axils of upper leaves; calyx-tube broadly 

 obconic, the lobes separated by wide sinuses, long, slender, acuminate, 

 entire or minutely dentate near the middle, reflexed after anthesis; 

 stamens 15-20; anthers light rose color; styles 2-4, surrounded at 

 the base by a narrow ring of pale hairs. Fruit ripening late in Sep- 

 tember, on long stout drooping pedicels, in few-fruited clusters, 

 subglobose or rather broader than long, light green when fully ripe, 

 becoming russet, 1.6-1.7 cm. in diameter; calyx little enlarged, 

 with a wide shallow cavity broad in the bottom, and small spreading 

 lobes dark red on the upper side below the middle and often deciduous 

 from the ripe fruit ; flesh thick, firm, light green ; nutlets 2-4, usually 

 3, rounded and obtuse at the ends, ridged and slightly grooved on the 

 back, 8.5-9 mm. long and 6.5-7 mm. wide.

 gray scaly bark, spreading branches, and slender nearly straight 

 branchlets dark orange-green and more or less tinged with red when
