or 4, usually 4. Fruit ripening in October, on slender elongated 

 pedicels, in drooping few-fruited clusters, subglobose to slightly

 blotched with green, pruinose, 8-11 mm. long and 8-10 mm. thick; 

 calyx prominent, with a short tube, a deep wide cavity broad in the 

 bottom, and spreading and reflexed persistent lobes ; flesh greenish 

 yellow, hard, dry and subacid; nutlets usually 4, rounded at the 

 ends, rather broader at the base than at the apex, slightly ridged on 

 the back, 6.5-7 mm. long and 4-4.5 mm. wide. 



A shrub 1.5-2 m. high, with small ascending stems, and slender

Leaves ovate to oval, acuminate, concave-cuneate at the base, 

 coarsely often doubly serrate, with straight glandular teeth, and 

 divided usually only above the middle into 4 or 5 pairs of small acumi- 

 nate lobes; nearly one-third grown when the flowers open about the 

 middle of May and then thin, dark yellow-green and roughened above 

 by short white hairs and paler and slightly villose, with persistent 

 hairs, along the midribs below, and at maturity thin but firm in texture, 

 dark blue-green and scabrate on the upper surface, pale bluish green 

 on the lower surface, 5-6 cm. long and 3.5-4 cm. wide, with slender 

 prominent midribs and veins; petioles slender, covered while young 

 with matted pale hairs, becoming glabrous, 2-3 cm. in length. Flowers 

 1.5-1.8 cm. in diameter, on short slender villose pedicels, in mostly 

 5-8 flowered corymbs, the elongated lower peduncles from the axils 

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

 short, slender, acuminate, entire or occasionally minutely dentate 

 near the middle, glabrous, reflexed after anthesis; stamens 18-20; 

 anthers pale yellow; styles 3-5. Fruit ripening in October, on short 

 stout drooping or spreading pedicels, in mostly 1-3-fruited clusters,

 with the pedicel, sometimes obtusely 4- or 5-angled, light yellow-
