dark persistent glands, 1.5-2 cm. long; stipules linear, lobed at the 

 base, villose, coarsely glandular-serrate, like the inner bud-scales, often 

 becoming bright red before falling; leaves on vigorous shoots broader, 

 full and rounded at the base, and often deeply lobed. Flowers 1.4 cm. in 

 diameter, on slender pedicels, in compact few-flowered glabrous com- 

 pound corymbs, with oblanceolate to linear, acuminate, finely glandular- 

 serrate bracts and bractlets, fading l^right red; calyx-tube broadly 

 obconic, glabrous, the lobes broad, acute or acuminate, laciniately 

 glandular-serrate, reflexed after anthesis; stamens 10; anthers pale 

 yellow; styles 3 or 4, surrounded at the base by a narrow ring of pale 

 tomentum. Fruit erect, in few-fruited clusters, globose to subglobose 

 or slightly obovate, about 1 cm. in diameter, dark green imtil late in the 

 season, becoming dark clear red when fully ripe; calyx prominent, 

 with a broad deep cavity, a short tube, and spreading mostly persistent 

 acuminate lobes often serrate above the middle; flesh thin, greenish, 

 dry and mealy; nutlets 3 or 4, thick, acute at the ends, prominently 

 ridged on the Ijack, with a broad often deeply grooved ridge, 7-8 mm. 

 long and 4-5 mm. wide. 



A tree-like shrub, with stems sometimes 3-4 m. high and stout zigzag 

 branchlets, light olive-green and glabrous when they first appear, dark 

 purple or reddish-brown and marked by numerous small oblong j^ale 

 lenticels durijig their first season and dark gray-brown in their second

Leaves oblong-ovate, acute or acuminate, abruptly or gradually con- 

 cave-cuneate at the glandular base, finely doubly serrate above, with 

 straight teeth tipped with dark red glands, and divided above the 

 middle into 3 or 4 pairs of short acute lobes, about half-grown when the 

 flowers open from the 15th to the 20th of ^lay and then membrana- 

 ceous, light yellow-green above, pale below, and glabrous with the ex- 

 ception of occasional pale hairs on the upper side of the midribs, and 

 at maturity thin and firm to subcoriaceous, dark yellow-green and 

 smooth on the upper and paler on the lower surface, 5-6 cm. long and 

 3-4 cm. wide, with slender yellow midribs and thin primary veins arch- 

 ing obliquely to the points of the lobes, turning orange color or crimson
