Leaves ovate to oblong-ovate, acuminate, concave-cuneate at the 

 entire or glandular base, coarsely doubly serrate above, with straight 

 gland-tipped teeth, and slightly divided into 4 or 5 pairs of small acute 

 lobes, when they unfold dark purple and coated above by long white 

 hairs and slightly hairy below on the midribs and veins, nearly half- 

 grown when the flowers open about the 20th of May and then membra- 

 naceous, light yellow-green and nearly glabrous on the upper and pale 

 or glaucous and glabrous on the lower surface, and at maturity thin 

 but firm in texture, dark yellow-green and scabrate or smooth above, 

 pale below, 5-6 cm. long, 3.5-4 cm. wide, with slender yellow midribs, 

 and obscure ]5rimary veiixs arching obliquely to the points of the lobes, 

 turning dull orange color or scarlet in the autumn before falling; peti- 

 oles slender, deeply grooved, narrowly wing-margined to below the 

 middle, sparingly villose on the upper side while young, soon glabrous, 

 glandular, with minute dark red stipitate glands, 1.5-2 cm. in length; 

 stipules linear, acuminate, glandular-serrate, caducous; leaves on vig- 

 orous shoots ovate, cuneate or rounded at the broad base, more coarsely 

 serrate, more deeply lobed, and 5-6 cm. long and broad. Flowers 

 1.5-1.7 cm. in diameter, on slender slightly hairy pedicels, in 3-6-flow- 

 ered simple corymbs, with linear obovate glandular-hispid bracts and 

 bractlets generally deciduous before the flowers open; calyx-tube 

 broadly obconic, glabrous, the lobes gradually narrowed from wide 

 bases, coarsely and irregularly serrate above the middle, or nearly 

 entire, glabrous on the outer, slightly villose on the inner surface 

 toward the apiculate glandular apex, reflexed after anthesis; stamens 

 8-10; anthers large, light purple; styles 2 or 3, surrounded at the base 

 by a ring of pale hairs. Fruit ripening from the 20th to the end of 

 September, on short stout erect reddish pedicels, solitary or in few- 

 fruited clusters, obovate, full and rounded at the apex, gradually nar- 

 rowed below the middle to the rounded base, dark reddish-orange 

 color, marked by occasional large dark dots, about 1.2 cm. long and 

 1-1.1 cm. wide; calyx little enlarged, with a small shallow cavity, and 

 spreading and reflexed lobes often deciduous from the ripe fruit; flesh 

 thin, orange color, dry and mealy; nutlets 2 or 3, full and rounded at 

 the base, gradually narrowed and rounded at the apex, ridged on the 

 back, with a wide deeply grooved ridge, light colored, 7-8 mm. lono- 

 and about 4 mm. wide.
