glandular, with minute glands, generalh' deciduous before the flowers 

 open. Flowers 1.8-2.2 cm. in diameter, on long stout glabrous 

 or rarely slightly hairy pedicels, in usually 6- or 7-flowered compact 

 corymbs, with large and conspicuous oblong-obovate to linear glandu- 

 lar-viscid bracts and bractlets persistent until the flowers open; calyx- 

 tube broadly obconic, glabrous, the lobes abruptly narrowed from wide 

 bases, slender, acuminate, glandular above the middle, with small 

 bright red stipitate glands, glabrous on the outer, sparingly villose on 

 the inner surface toward the apex; stamens 10-18, usually 10-11; 

 anthers cream color; styles 3-5, rarely 3. Fruit ripening toward the 

 middle of October and often persistent until the middle of November, 

 on stout reddish elongated erect pedicels, in few-fruited clusters, obo- 

 vate w^hen fully grown, becoming globose or depressed-globose and 

 slightly tapering to the base or rarely pyriform-globose or oblong- 

 globose at maturity, full and rounded at the apex, gradually narrowed 

 to the base, dark red, sparingly blotched with russet or dark green, 

 marked by many small pale green dots, 1.2-1.4 cm. long and 1.4-1.7 

 cm. thick; calyx little enlarged, with a long narrow prominent tube 

 and reflexed lobes mostly deciduous from the ripe fruit; flesh thin, 

 greenish-yellow and dry; nutlets 4 or 5, full and rounded at the base, 

 gradually narrowed and rounded at the apex, ridged on the back, with 

 a broad low slightly grooved ridge, about 8 mm. long and 4 mm. wide. 



A narrow shrub about 2 m. high, with erect stems covered with dark 

 brown bark, and slender nearly straight branchlets marked by occa- 

 sional small oblong pale lenticels, orange or purplish when they first 

 appear, bright chestnut-brown and lustrous during their first year and 

 dark dull brown the following season, and armed with slender nearly

Leaves ovate to oval or rarely slightly obovate, acute or acuminate, 

 gradually narrowed into a long concave-cuneate glandular base, sharply 

 doubly serrate above, with gland-tipped teeth, and divided above the 

 middle into 3 or 4 pairs of large acute spreading or reflexed lobes, w^hen 

 they unfold dark red and slightly hairy on the upper and faintly tinged 

 with red and glabrous on the lower surface, nearly half-grown when the 

 flowers open about the 20th of May and then membranaceous, dark
