deep narrow cavity tomentose in the bottom, and spreading often 

 deciduous lobes; flesh thin, green and firm; nutlets 3 or 4, gradually 

 narrowed and rounded at the ends, ridged on the back, with a broad 

 high grooved ridge, 6-6.5 mm. long and 4-4.5 mm. wide. 



A shrub 1.5-2 m. high, with slender stems, and stout zigzag branch- 

 lets dark olive green and covered with long pale hairs when they first 

 appear, becoming light chestnut brown, lustrous, glabrous, and 

 marked by dark lenticels in their first season and dull green the fol-

Glabrous with the exception of the hairs on the calyx-lobes. Leaves 

 oval to slightly obovate, acute at the ends and usually 3.5 cm. long 

 and 2.5 cm. wide, to broadly ovate and acute at the apex, abruptly 

 cuneate at the base and usually 3-3.5 cm. long and broad, finely often 

 doubly serrate, with short straight or incurved glandular teeth, and 

 sometimes slightly divided above the middle into 2 or 3 pairs of short 

 broad acuminate lobes; deeply tinged with red when they unfold, 

 nearly fully grown when the flowers open from the middle to the 

 20th of May and then light yellow-green and smooth above and pale 

 below, and at maturity thin, dark yellow and lustrous on the upper 

 surface, very pale and yellow below, with thin prominent midribs 

 and primary veins, and conspicuous reticulate veinlets; petioles slen- 

 der, narrowly wing-margined to below the middle, glandular, with 

 minute deciduous glands, 1-1.8 cm. in length; leaves on vigorous 

 shoots broadly ovate, rounded at the wide base, more coarsely serrate 

 and more deeply lobed, and often 4-5 cm. long and wide. Flowers 

 2 cm. in diameter, on short slender pedicels, in small compact mostly 

 6-12-flowered corymbs, with oblong-obovate to linear glandular- 

 serrate bracts and bractlets fading brown and persistent until the 

 flowers open, the long lower peduncles from the axils of upper leaves ; 

 calyx-tube narrowly obconic, the lobes long, wide, coarsely glandular- 

 serrate, glabrous on the outer surface, sparingly villose on the inner 

 surface, reflexed after anthesis; stamens 10; anthers dark rose color; 

 styles 2 or 3, usually 3, surrounded at the base by a narrow ring of 

 pale tomentum. Fruit ripening late in October, on short slender 

 erect or spreading pedicels, in compact usually 4-9-fruited clusters, 

 short-oblong to slightly obovate, full and rounded at the ends, bright 

 canary yellow, marked by numerous large dark dots, 1-1.4 cm. in
