 or narrow-ovate, acuminate, concave-cuneate and gradually narrowed 

 to the stout petioles, broadly wing- margined nearly to the base, 

 deeply lobed, very coarsely serrate, 9-10 cm. long and 4.5-5.5 cm. 

 wide, their stipules foliaceous, lunate, acuminate, coarsely glandular- 

 serrate, persistent through the season. Flowers about 1.5 cm. in 

 diameter on slender pedicels, in wide lax many-flowered thin-branched 

 compound corymbs ; bracts and bractlets linear, acuminate, mostly 

 deciduous before the flowers open ; calyx broadly obconic, the lobes 

 separated by wide rounded sinuses, gradually narrowed from the base 

 into long slender acuminate entire tips, reflexed after anthesis ; 

 stamens 20 ; anthers small, red or deep rose color ; styles 3 or 4, 

 surrounded at the base by a narrow ring of pale tomentum. Fruit on 

 slender pedicels, in abundant drooping many-fruited clusters, oblong, 

 full and rounded at the apex, depressed at the insertion of the stalk, 

 dull scarlet, marked by occasional dark dots, i. 2-1.4 cm. long, 8-9 

 mm. wide ; calyx sessile, with a narrow shallow cavity and only 

 slightly enlarged reflexed and appressed lobes dark red on the upper 

 side near the base, their tips often deciduous from the ripe fruit ; flesh 

 thick, yellow, rather juicy, of a disagreeable flavor ; nutlets 3 or 4, 

 usually 4, thick, full and rounded at the ends, ridged on the back 

 with a high narrow ridge, 7 mm. long. 



A shrub from 2 to 4 m. in height, with ascending and spreading 

 stems covered with rough scaly dull gray bark, and slender zigzag 

 branchlets, light red-brown and marked by many small pale lenticels 

 •when they first appear, pale brown at the end of their first season, 

 becoming ashy gray or gray tinged with red the following year, and 

 armed with many stout curved or slender nearly straight bright red or 

 purple shining spines, from 4 to 5 cm. in length. Flowers during the 

 first week of June. Fruit ripens at the end of September and does 

 not entirely fall until after the middle of October.
