anthers rich purple; styles 2-4, usually 3, surrounded at the base by a 

 narrow ring of hoary tomentum. Fruit ripening the end of August 

 and falling as soon as ripe, on elongated slender pedicels, in wide droop- 

 ing clusters, short-oblong or rarely depressed-globose, scarlet often 

 blotched with russet, concave at the base, lustrous, marked by small 

 pale dots, 1.2-1.4 cm. long, 1.1-1.2 cm. thick; calyx little enlarged with 

 a wide shallow cavity, and spreading closely appressed lobes mostly 

 persistent on the ripe fruit; flesh orange-yellow, soft; nutlets 3, gradu- 

 ally narrowed and rounded at the ends, only slightly ridged on the back, 

 with a broad low ridge, about 7 mm. long and 4 mm, wide. 



A shrubby tree 3-4 m. high, with a trunk 20-30 cm. in diameter, 

 covered with ashy-gray scaly bark, and dividing near the ground into 

 numerous ascending gray branches forming a narrow oval head, and 

 slender nearly straight branchlets marked by small pale lenticels, light 

 red-brown during their first season and light gray-brown to ashy-gray 

 the following year, and sparingly armed with slender straight or re- 

 curved chestnut-brown spines, becoming ultimately dark gray and

Leaves ovate, acuminate, rounded, truncate or occasionally cuneate 

 at the wide glandular base, sharply doubly serrate above, with straight 

 glandular teeth and slightly divided into 2 or 3 pairs of broad acute 

 lateral lobes, about one-third grown when the flowers open the middle 

 of May and then membranaceous, yellow-green and slightly roughened 

 above by short white hairs, pale and glabrous below, and at maturity 

 thin but firm in texture, glabrous, dark bluish-green and lustrous on the 

 upper and pale on the lower surface, 6-6.5 cm. long, 5.5-6 cm. wide, 

 with slender midribs and usually 4 pairs of thin primary veins extend- 

 ing obliquely to the points of the lobes ; petioles slender, slightly wing- 

 margined at the apex, glabrous, glandular, with persistent glands, 

 2.5-3.5 cm. in length. Floivers 1.4-1.8 or occasionally 2 cm. in diam- 

 eter, on stout pedicels, in compact usually 5-10-flowered corymbs; 

 calyx-tube narrowly obconic, the lobes very slender, long-acuminate, 

 usually entire or furnished above the middle with an occasional toothy 

 reflexed after anthesis ; stamens 5-10; anthers light purple ; styles 2-4,
