mostly 10-15-flowered corymbs, the lower peduncles from the axils 

 of upper leaves; calyx-tube narrowly obconic, the lobes wide, elong- 

 ated, coarsely glandular-serrate, glabrous on the outer surface, villose 

 on the inner surface, reflexed after anthesis; stamens 20; anthers 

 pale pink; styles 2 or 3. Fruit ripening late in September, on long 

 drooping pedicels, in few-fruited clusters, ovate to oval, orange-red, 

 lustrous, 7-8 mm. long and 6-7 mm. wide; calyx prominent, with a 

 short tube, a deep narrow cavity, and spreading often deciduous lobes; 

 flesh thin, yellow, dry and mealy; nutlets 2 or 3, rounded at the apex, 

 gradually narrowed at the base, only slightly ridged on the back, 

 penetrated on the inner faces by long deep cavities, about 5 mm. long 

 and 3.5-4 mm. wide. 



A shrub 3-4 m. high, with small stems spreading into large dense 

 round-topped thickets, small erect branches, and stout nearly straight 

 branchlets dark orange-green and marked by pale lenticels when they 

 first appear, becoming light chestnut brown and very lustrous in their

Glabrous with the exception of the hairs on the inner surface of 

 the calyx-lobes. Leaves obovate, broad and rounded or acute and 

 short-pointed at the apex, gradually narrowed to the cuneate base, 

 coarsely often doubly serrate usually only above the middle, with 

 straight glandular teeth, and occasionally slightly lobecl, with broad 

 acute lobes; when the flowers open at the end of May thick, dark 

 yellow-green and very lustrous above and pale below, and at maturity 

 subcoriaceous, glabrous, dark yellow-green, smooth and lustrous on 

 the upper surface, paler on the lower surface, 4-5 cm. long and 3.5-4 

 cm. wide, with stout midribs, and prominent primary veins connected 

 by conspicuous reticulate veinlets and deeply impressed on the upper 

 side of the leaf; petioles stout, narrowly wing-margined nearly to the 

 base, 8-10 mm. in length; leaves on vigorous shoots thicker, more 

 coarsely serrate, usually acuminate at the apex, 6-7 cm. long and 5-6
