4-6 cm. wide, with stout midribs deeply impressed on the upper side 

 and usually rose-colored below late in the season, and 3-5 pairs of 

 thin primary veins arching obliquely to the points of the lobes ; 

 petioles slender, more or less wing-margined at the apex by the decur- 

 rent base of the leaf-blades, grooved, sparingly hairy early in the 

 spring, glandular, with numerous small dark persistent glands, 1.5-3 

 cm. in length. Flowers about 1.8 cm. in diameter on short stout 

 pedicels, in narrow compact 3-10, usually 5 or 6-fiowered compound 

 corymbs ; bracts and bractlets oblong-obovate, acuminate, very 

 glandular, large and conspicuous, often deciduous before the flowers 

 open ; calyx-tube broadly obconic, the lobes gradually narrowed from 

 wide bases, broad, acuminate, coarsely glandular-serrate, usually only 

 above the middle, reflexed after anthesis ; stamens 10 ; anthers large, 

 pale yellow ; styles 4 or 5, surrounded at the base by a broad ring of 

 pale hairs. Fruit on short stout reddish pedicels, in few-fruited erect 

 clusters, subglobose, flattened at the ends, concave at the base at the 

 insertion of the stalk, bright orange-red, lustrous, marked by numer- 

 ous large pale dots, about 1.5 cm. in diameter; calyx prominent, 

 with a broad deep cavity, and wide lobes gradually narrowed into the 

 long slender acuminate glandular-serrate reflexed and closely 

 appressed tips often deciduous from the ripe fruit ; flesh thin, hard 

 and dry, greenish yellow ; nutlets 4 or 5, broad, obtuse at the 

 narrowed ends, ridged and slightly grooved on the back, about 7 mm. 

 long and 5 mm. high. 



An intricately branched shrub 3 or 4 m. in height with numerous 

 stout stems covered with dark scaly bark, and erect and spreading 

 branches forming a broad round-topped head, and slender only 

 slightly zigzag branchlets, orange-green and marked by numerous 

 large pale lenticels when they first appear, light red-brown and 

 lustrous at the end of their first season, becoming light gray the 

 following year, and armed with many slender or stout nearly straight 

 bright red-brown shining spines 2.5-4 cm. in length. Flowers from 

 the end of May to the loth of June. Fruit ripens the middle of 

 October and does not fall until the last of October or the first of 

 November. In the autumn the leaves turn a handsome yellowish red
