40681. BERBERIS POTANINL Barberry. From F. N. 

 Meyer, Hsiku, Kansu, China. A shrub 3 to 5 feet high, with rather 

 stout branches. Very spiny, glistening foliage; bearing a profusion 

 of scarlet berries nearly one-half inch long. Remarkable for its 

 large fruit and scarlet leaves in the fall. Very drought resistant. 



13353. BERBERIS SIEBOLDI. Barberry. From the Central 

 Experimental Farm, Ottawa, Canada, through David Fairchild. A 

 hardy, deciduous shrub of rounded form, native of Japan. Very 

 similar to B. vulgaris, but more dwarf in habit, usually below 3 feet 

 in height. Leaves thin, medium size, 1 to 2| inches long. Fruit 

 round, bright yellowish red. 



X BERBERIS STENOPHYLLA. Hybrid barberry. Hand- 

 some evergreen bush, forming a dense thicket of slender interlacing 

 stems. Cross between B. darwinii and B. empetrifolia. Said to 

 produce a mass of rich, golden-yellow flowers in spring, and to be 

 useful as a lawn bush, covering for a steep bank, or as a hedge plant. 

 Reported hardy in sheltered places at Arnold Arboretum, Boston. 



28380. BERBERIS THUNBERGII X VULGARIS ATRO- 

 PURPUREA. Hybrid barberry. Produced by Dr. Walter Van 

 Fleet. Very handsome, yellow-flowered shrub of somewhat more 

 open habit than B. thunbergii and possessing slightly larger leaves, 

 which, however, retain the beautiful deep-purple color of B. vulgaris 

 atropurpurea. A very promising ornamental, deserving trial as a 

 park, lawn, or garden shrub. 



BERBERIS WILSONAE. Mrs. Wilson's barberry. A dwarf, 

 much-branched shrub, densely clothed with gray-green leaves about 

 half an inch long, which turn a beautiful crimson in the fall. Spines 

 nearly an inch long. Flowers a rich golden. Noteworthy for its 

 nearly round, coral or salmon red, somewhat translucent fruits, which 

 are borne very abundantly. Discovered by E. H. Wilson in western 

 China. 



BERBERIS YUNNANENSIS. Western Chinese Barberry. 

 Handsome, deciduous, spiny shrub, 3 to 6 feet high, of dense rounded 

 habit. The leaves, mostly entire on the flowering shoots but toothed 

 on the others, turn a brilliant crimson in the autumn. The pale- 

 yellow, clustered flowers (three-fourths of an inch across) and the 

 bright-red, oval berries (one-half inch long) are among the largest in 

 the genus.
