conic, glabrous, the lobes gradually narrowed from wide bases, acumi- 

 nate, entire with slightly undulate margins, or occasionally furnished 

 with 1 or 2 teeth near the middle, reflexed after anthesis ; stamens 16-20 ; 

 anthers pale pink; styles usually 5, surrounded at the base by a con- 

 spicuous ring of long white hairs. Fruit ripening from the first to the 

 middle of October, on short stout erect pedicels, in mostly .3-5-flowered 

 clusters, depressed-globose, full and rounded at the base, more or less 

 angled, green and lustrous until late in the season, marked by many 

 large dark dots, becoming finally light red, 1.7-2 cm. in diameter and 

 1.5 cm. high; calyx much enlarged, without a tube and with a broad 

 deep cavity, and spreading often incurved lobes slightly and irregularly 

 serrate particularly toward the apex, red on the upper side below the 

 middle, and mostly deciduous from the ripe fruit; flesh thick, pale 

 yellow, dry and mealy; nutlets 3-5, usually 5, full and rounded at the 

 ends, prominently ridged on the back, with a broad deeply grooved 

 ridge, about 7 mm. long and 4 mm. wide. 



A broad shrub, with numerous erect stems 3-4 m. high, and slender 

 nearly straight ])ranchlets marked by many pale lenticels, dark red- 

 brown and covered with a glaucous bloom when they first appear, 

 darker and very lustrous during their first winter, dark gray-ljrown the 

 following year and armed with nearly straight slender red-brown 

 lustrous spines 3.5-5 cm. in length.

Leaves ovate to deltoid, acuminate, rounded, truncate or rarely con- 

 cave-cuneate at the entire or glandular base, sharply doubly serrate 

 above, with straight gland-tipped teeth, and deeply divided into 3 or 4 

 pairs of narrow acuminate lobes, more than half -grown when the flowers 

 open from the 10th to the 15th of May and then very thin, bright yel- 

 low-green, slightly hairy and scabrate above, soon becoming smooth 

 and glabrous, and pale or glaucous and glabrous below, and at maturity 

 thin and firm in texture, dark yellow-green on the upper and pale on 

 the lower surface, 3-5 cm. long, 2-5 cm. wide, and often rather broader 

 than long, with slender yellow midribs, and thin primary veins arching 

 obliquely to the points of the lobes; petioles slender, grooved on the 

 upper side, slightly wing-margined at the apex, glandular, with minute 

 persistent glands, glabrous, 1-1.5 cm. in length; leaves on vigorous 

 shoots broadly ovate, rounded to subcordate at the base, coarsely 

 .serrate, usually deeply divided into broad acuminate lateral lobes,
