leaves on vigorous shoots broadly ovate, often full and rounded at the

 not more than 1 cm. long. Flowers about 1.4 cm. in diameter, on 

 slender elongated glabrous pedicels, in usually 6-8-flowered compound 

 corymbs, with large oblong-obovate viscid bracts and bractlets con- 

 spicuously glandular with large long-stalked dark glands, fading rose 

 color, persistent until after the petals have fallen; calyx-tube broadly 

 obconic, the lobes large, acuminate, coarsely glandular-serrate above 

 the middle, glabrous, reflexed after anthesis; stamens 5-10; anthers 

 cream color; styles 3, surrounded at the base by a narrow ring of hoary 

 tomentUm. Fruit ripening toward the end of September and falling 

 before the middle of October, on slender erect or spreading pedicels, in 

 usually 2- or .3-fruited clusters, short-oblong, full and rounded at the 

 apex, gradually narrowed to the base, dark orange or reddish-orange 

 color marked by numerous large dark dots, 1-1.2 cm. long, 9-10 mm. 

 wide; calyx enlarged and prominent, with a short tube, a wide deep 

 cavity, and spreading lobes mostly persistent on the ripe fruit; flesh 

 thin, greenish, dry and mealy; nutlets 3, rounded at the ends, irregu- 

 larly ridged or grooved on the back, about 7 mm. long and 4-5 mm.
