Western Hupeh : Patung Hsien, thickets, alt. 1300 m., June and 

 July 1907 (No. 2878; with flowers and immature fruit). Western 

 Szech'uan : mountain sides, Ching-chi Hsien, alt. 1600 m., November 

 1908 (No. 2876; with mature fruit); west and near Wen-ch'uan Hsien, 

 mountain sides, alt. 1600-2000 m., August 10, 1908 (No. 2877; shrub 

 1-1.5 m. tall, with unripe fruit). 



This species seems to be most nearly related to B. pruinosa Franchet, which is 

 distinguished by the stronger spines of the leaves and by the fruits without styles 

 and with 2-4 seeds. 



To B. Bergmanniae may also belong David's specimen, which he collected in 

 Mupin, April 1869 (shrub 3 m. tall; ravines). 



Tliis species is named in honor of Mrs. Marie Bergmann of Vienna. 



Berberis Bergmanniae, var. acanthophylla Schneider, n. var. 



A typo recedit foliis crasse sinuato-spinoso-dentatis, dentibus 

 foliorum maximorum ad 5:2 cm. magnorum utrinque tantum 4-5, 

 subtus laete virentibus. 



Western Szech'uan: west and near Wen-ch'uan Hsien, alt. 

 2000-2500 m., November 1910 (No. 4149; shrub 1-1.5 m. tall, fruit 

 blue-black) . 



This variety is well marked by its leaves, but the blue-black fruits with their 

 red pedicels and with two seeds closely resemble those of the type.
