456 BUSH-FRUITS 



margins; stamens several times as long as the petals; filaments 

 slender, slightly pubescent; style 2-cleft, smooth, like the sta- 

 mens, projecting beyond the calyx lobes; berry smooth, of me- 

 dium size, dark purple or brownish. 



Michigan to Tennessee, and westward to Texas and the Eocky 

 Mountains. 



This is the common species of the Plains. It is readily dis- 

 tinguished by the finely divided, fragile appearance of the flower. 

 Although not in cultivation, its adaptibility to the Plains might 

 render it of especial value for that region if improved. 



13. E. CURVATA, Small. 



Low, diffusely branched shrub, the older parts covered with 

 loose, papery bark, the younger branches small, wiry, smooth and 

 shining, reddish or purplish in color; thorns slender, obliquely 

 recurved, %-/ inch (3-6 mm.) long; leaves small, %-% inch 

 (10-20 mm.) in diameter, suborbicular ; lobes rounded, not deeply 

 cut, thick and beset with resinous dots; petioles rather slender 

 and villous; peduncles slender, commonly one, sometimes two- 

 flowered; flowers finely divided and fragile; calyx-tube very short; 

 segments long and narrow, reflexed, white or greenish white; 

 petals minute ; filaments long and slender, pubescent or somewhat 

 villous; style villous, slightly 2-cleft; ovary smooth; berry round, 

 smooth and small. 



Described from Stone Mountain, Georgia. 



This is evidently the southeastern representative of E. gracile. 

 It differs from that species in its smooth, shining branchlets, 

 smaller recurved thorns, smaller, thicker and less sharply cut 

 leaves, which bear resinous dots. 



14. E. NIVEUM, Lindl. 



Shrub 4-6 feet (12-18 decimeters) high, with slender, upright 

 twigs and branches, and single to triple thorns; leaves roundish, 

 entire at base, 3-5 lobed, somewhat pubescent when young, gla- 

 brous when older; petioles long and slender; peduncles slender, 

 drooping, 1-4 flowered, the very slender pedicels subtended by 

 small, broad bracts; calyx-tube smooth, short, bell-shaped; 

 lobes long, lanceolate, at first upright, later reflexed, white and 

 glabrous; petals white, wedge-shaped, much shorter than the 

 calyx lobes; stamens slightly longer than the calyx lobes, fila- 

 ments hairy; style 2-cleft, villous; ovary smooth; berry round, 

 smooth, bluish black, about the size of a black currant. Lindley
