 at maturity thin, smooth, dark yellow-green on the upper and paler on 

 the lower surface, 4-5 cm. long and 2.5-3 cm. wide, with slender yellow 

 midribs and thin primary veins arching to the points of the lobes; 

 petioles slender, slightly grooved on the upper side, more or less wing- 

 margined toward the apex, glandular, with minute persistent dark 

 glands, 1-2 cm. in length; stipules lanceolate, glandular, fading brown, 

 usually deciduous before the flowers open; leaves on vigorous shoots 

 broadly ovate, abruptly cuneate at the wide base, often three-lobed by 

 deep narrow sinuses, coarsely serrate, frequently 6 cm. long and 

 wide, with stout broadly winged conspicuously glandular petioles. 

 Flowers 1.6-1.8 cm. in diameter, on long slender glabrous pedicels, in 

 usually 4-6-flowered corymbs, with oblong-obovate to linear glandular 

 bracts and bractlets mostly deciduous before the flowers open; calyx- 

 tube narrowly obconic, the lobes slender, acuminate, entire or slightly 

 serrate toward the apex, reflexed after anthesis ; stamens 8-10 ; anthers 

 pale pink; styles 3 or 4. Fruit ripening the middle of October and

 ridge, 8-9 mm. long and about 5 mm. wide. 



A shrub 2-3 m. high, with numerous small erect dark stems forming 

 an open irregular head and slender nearly straight branchlets marked 

 by minute dark lenticels, light orange color when they first appear,
