base, coarsely serrate, often 6-7 cm. long and 5-6 cm. wide. Flowers 

 1.8 cm. in diameter, on short slender villose pedicels, in small com- 

 pact hairy mostly 5-7-flowered crowded corymbs, with conspicuous 

 oblong-obovate to linear glandular-serrate bracts and bractlets 

 fading brown and persistent until the flowers open, the lower peduncle^ 

 from the axils of upper leaves; calyx-tube narrowly obconic, coated 

 with matted pale hairs, the lobes long, slender, acuminate, finely 

 glandular-serrate, glabrous on the outer surface, slightly villose 

 on the inner surface, refiexed after anthesis; stamens 10; anther- 

 very large, pale cream color; styles 3 or 4, surrounded at the base 

 by a broad ring of pale tomentum. Fruit ripening early in October 

 and generally persistent after the leaves fall, on short stout villose 

 erect pedicels, in mostly 2-5-fruited clusters, short-oblong to sub- 

 globose, truncate at the apex, rounded or flattened at the base, russet- 

 green with a dark russet-red cheek, marked by numerous dark dots. 

 1.2-1.7 cm. in diameter; calyx prominent, with a short tube, a wide 

 deep cavity pointed in the bottom, and spreading and refiexed per- 

 sistent lobes; flesh thin, rather juicy, light yellow-green; nutlets 

 3 or 4 usually 3. broad and rounded at the ends, ridged on the back, 

 with a broad low ridge, 6.5-7 mm. long and 5 mm. wide. 



A shrub 1-2 m. high, with small spreading stems, and stout nearly 

 straight branchlets dark orange-green, villose and marked by pale

Leaves ovate, acute or acuminate, rounded or abruptly cuneate 

 at the wide base, finely doubly serrate, with straight glandular teeth, 

 and slightly divided into 4 or 5 pairs of small acute lateral lobes ;

 then thin, yellow-green and roughened above by short white hairs and 

 villose on the midribs and veins below, and at maturity thin, yellow- 

 green and scabrate on the upper surface and still hairy on the lower 

 surface on the prominent midribs and thin primary veins; petioles 

 slender, slightly wing-margined at the apex, glandular, with minute
