lar, with occasional minute caducous glands, and 1.5-2.5 cm. in length; 

 stipules linear, acuminate, glandular, caducous; leaves on leading 

 shoots broadly ovate, rounded or cuneate at the base and decurrent 

 on the stout petioles, more coarsely serrate and more deeply lobed, 

 villose on the under side of the midribs and veins and often 5.5-6 cm. 

 long and 5 cm. wide. Flowers 1.5-1.7 cm. in diameter, on elongated 

 slender slightly villose pedicels, in mostly 5- or 6-flowered compact 

 villose corymbs, with linear acuminate glandular bracts and bractlets, 

 fading brown and mostly persistent until after the petals have fallen; 

 calyx-tube narrowly obconic, glabrous, the lobes gradually narrowed 

 from broad bases, acuminate, sharply glandular-serrate above the 

 middle, reflexed after anthesis; stamens 17-20; anthers pink; styles 

 3-5, surrounded at the base by a broad ring of matted pale hairs. 

 Fruit ripening about the first of October, on slender erect glabrous or 

 occasionally slightly villose pedicels, depressed-globose, olive-green 

 rarely with a rose-flushed cheek, 9-10 mm. in diameter; flesh thin, dry 

 and hard; calyx enlarged and prominent, without a tube and with a 

 wide deep cavity, and small reflexed and closely appressed lobes dark 

 red on the upper side tow^ard the base and mostly persistent on the ripe 

 fruit; nutlets 3-5, thick, rounded at the ends, irregularly ridged on the 

 back, often with a high grooved ridge, 6-7 mm. long and about 4 mm. 

 wide. 



A shrub 3-5 m. high, spreading into broad thickets, with many erect 

 stems, and slender nearly straight branchlets marked by many small 

 pale lenticels, reddish-brown and slightly villose when they first appear, 

 soon glabrous, dull red-brown in their first season, and dark brown 

 tinged with red the following year, and armed with numerous verv 

 slender straight or slightly curved red-brown or purple spines often 6-7

Leaves ovate, acuminate, full and rounded or abruptly concave- 

 cuneate at the base, finely often doubly serrate, with straight glandular 

 teeth, and divided above the middle into several short acuminate 

 lateral lobes, dark vinous red, and covered with long caducous hairs 

 when they unfold, more than half-grown when the flowers open the 

 middle of May and then scabrate and slightly hairy along the midribs 

 above and sparingly villose below at the junction of the midribs and 

 veins, and at maturity glabrous, subcoriaceous, blue-green and still 

 rough on the upper, paler and yellow-green on the lower surface, 4-7 cm.
