acuminate, deeply glandular-serrate, with small bright red glands, 

 glabrous on the outer, hairy on the inner surface, with pale matted 

 hairs, reflexed after anthesis; stamens 20; anthers dark rose color; 

 styles 2 or 3. Fruit ripening the end of September and soon falling, on 

 slender erect reddish pedicels, in few-fruited clusters, subglobose, 

 orange-red, lustrous, marked by occasional pale dots, 7-8 mm. in diam- 

 eter; calyx little enlarged, with a short tube, a narrow deep cavity, 

 and closely appressed lobes often deciduous from the ripe fruit; flesh 

 very thin, yellow, dry and mealy; nutlets 2 or 3, obtuse at the ends, 

 ridged on the back, with a high narrow ridge, penetrated on the inner 

 face by broad shallow grooves, about 4 mm. long and 3 mm. wide. 



A shrub with numerous small much-branched stems 2-3 m. high, 

 with slender nearly straight branchlets marked by oblong pale lenticels, 

 dark orange-colored and glabrous when they first appear, becoming 

 light chestnut-brown and very lustrous during their first season and

Leaves rhombic to oval, acuminate, concave-cuneate at the entire 

 base, finely often doubly serrate above, and sometimes slightly divided 

 toward the apex into 3 or 4 pairs of broad acute lobes, nearly fully 

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

 branaceous, dark yellow-green, very smooth and puberulous along 

 the midribs above and pale or glaucous and glabrous with the excep- 

 tion of a few short hairs in the axils of the veins below, and at maturity 

 coriaceous and glabrous, dark green and lustrous on the upper and pale 

 and conspicuously reticulate-venulose on the lower surface, 6-7 cm. 

 long and 4-5 cm. wide, with stout orange-colored midribs, and slender 

 veins extending obliquely to the points of the lobes; petioles stovit, 

 broadly wing-margined from the apex sometimes to below the middle, 

 deeply grooved, without glands, puberulous while young on the upper 

 side, soon glabrous, 1.5-2 cm. in length; stipules linear-lanceolate, 

 minutely glandular, fading brown, caducous. Flowers 1.4-1.6 cm. in 

 diameter, on stout elongated villose pedicels, in broad many-flowered 

 compact hairy corymbs, with oblong-obovate to linear acuminate
