shoots thicker, cordate or truncate at the base, more coarsely serrate 

 more deeply lobed, and sometimes 6-6.5 cm. long and broad, with 

 stout glandular petioles. Flowers 1.2-1.4 cm. in diameter, on long 

 stout pedicels, in small 5- or 6-flowered corymbs, the elongated lower 

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

 the lobes gradually narrowed from wide bases, long, slender, acumin- 

 ate, entire or minutely glandular-dentate near the middle, reflexed 

 after anthesis; stamens 10; anthers rose color; styles 3-5. Fruit 

 ripening early in October, on stout pedicels, in few-fruited clusters, 

 short-oblong, full and rounded at the ends, dull scarlet, 1.2 cm. long 

 and nearly as broad; flesh thin and yellow; nutlets 3-5, rounded at 

 the base, gradually narrowed and rounded at the apex, or when 5 

 acute at the ends, ridged on the back, with a high narrow slightly 

 grooved ridge, about 6 mm. long and 4 mm. wide. 



A shrub 3-4 m. high, with small stems covered with ashy gray 

 bark, small spreading branches forming a round-topped head, and 

 slender only slightly zigzag branchlets dark orange-brown and marked 

 by pale lenticels when they first appear, becoming light chestnut 

 brown and lustrous in their first season and dull gray-brown the 

 following year, and armed with stout slightly curved chestnut brown

Glabrous with the exception of the hairs on the young leaves and 

 calyx-lobes. Leaves broadly ovate, acuminate and frequently long- 

 pointed at the apex, rounded or abruptly cuneate at the broad entire 

 base, coarsely often doubly serrate above, with straight glandular 

 teeth, and slightly divided usually only above the middle into 3 or 4 

 pairs of short broad lobes; more than half grown when the flowers 

 open about the 20th of May and then thin, yellow-green and roughened 

 above by short white hairs and pale blue-green below, and at maturity 

 thin but firm in texture, dark yellow-green, nearly smooth and lus- 

 trous on the upper surface, pale blue-green on the lower surface, 

 5-6 cm. long and 4.5-5 cm. wide, with thin prominent midribs and 

 slender conspicuous primary veins; petioles slender, slightly wing- 

 margined at the apex, glandular, with conspicuous persistent glands, 

 2.5-3 cm. in length; leaves on vigorous shoots cuneate, rounded or 

 slightly cordate at the base, coarsely serrate, more deeply lobed 

 and often 7-8 cm long and 6-7 cm. wide, with stouter broadly winged 

 more glandular petioles. Flowers 2 cm. in diameter, on long slender
