of the leaves, on slender pedicels, in spreading few-fruited clusters, 

 globose to oblong-globose, often slightly tapering at the base, scarlet, 

 sparingly blotched with orange or russet, 1.3-1.7 cm. long; calyx en- 

 larged with a broad shallow cavity and spreading and incurved lobes; 

 flesh thick, juicy, soft, yellow or orange, sweetish acid ; nutlets usually 

 3 or 4, full and rounded at the base, gradually narrowed to the rounded 

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

 ridge, 7-8 cm. long and 3-4 cm. wide. 



A tree sometimes 4 m. high, with a short trunk 25-30 cm. in diameter 

 covered with rough ashy-gray to dark gray bark, spreading and ascending 

 stout fiexuose gray branches forming a broad round-topped head, and 

 slender slightly zigzag branchlets marked by numerous pale lenticels, 

 dark green tinged with red when they first appear, bright chestnut- 

 brown and very lustrous during their first winter, becoming dull gray- 

 brown the following year, and armed with numerous stout conical 

 spines brown or purplish-brown during their first season, dark gray the 

 following year and 1-3 cm. in length, becoming on old trunks elongated 

 and much-branched.

Leaves oblong-ovate, acuminate, full and rounded at the entire base, 

 coarsely serrate above, with broad glandular teeth, and slightly divided 

 into 3 or 4 pairs of short acute spreading lobes, nearly half-grown when 

 the flowers open about the 20th of May and then very thin, light yellow- 

 green and slightly roughened above by short white hairs and pale and 

 glabrous below, and at maturity thin but firm in texture, dark yellow- 

 green, smooth and glabrous on the upper and light yellow-green on the 

 lower surface, 5-7 cm. long and 4.5-5.5 cm. wide, with stout yellow 

 midribs, and slender primary veins arching obliquely to the points of 

 the lobes; petioles stout, usually without glands, 2-3 cm. in length. 

 Flowers about 1.2 cm. in diameter, on short stout glabrous pedicels, in 

 crowded compact usually 8-12-flowered corymbs, with linear glandular 

 bracts and bractlets mostly deciduous before the flowers open; calyx- 

 tube narrowly obconic, the lobes gradually narrowed from broad bases, 

 slender, acuminate, entire or occasionally sparingly toothed, reflexed 

 after anthesis ; stamens 6-8; anthers purple ; styles 2 or 3; surrounded 

 at the base by a narrow ring of hoary tomentum. Fruit ripening the 

 middle of September, on short stout pedicels, in few-fruited drooping 

 clusters, obovate, yellowish-red and lustrous, about 1 cm. long and 

 8-10 mm. wide; calyx little enlarged, with a narrow shallow cavity, and
