Berberis Bergmanniae Schneider, n. sp. 
Frutex 1-2-metralis; ramuli juniores non visi, biennes v. vetus- 
tiores flavescentes v. flavocinerei, satis crassi, angulati, leviter divari- 
cati, glabri, deinde cinerei; internodia 2 cm. ad 3.5 em. longa; spinae 
plerumque trifidae, validae, flavescentes, mediae ad 3.5 cm. longae, 
fere rotundae. Folia ad circiter 5-fasciculata, crasse coriacea, ovato- 
v. obovato-elliptica, apice breviter acuta, spinosa, basim versus 
sensim in petiolum brevissimum v. nullum contracta; 2:1 v. 2.5:0.9 
cm. ad 4.5:1.7 em. magna, supra viridia, nitentia, subtus pallidiora 
v. pruinosa, nervo mediano elevato lateralibus minus quam supra 
visibilibus, margine spinoso-dentata dentibus gracilibus sed pun- 
gentibus utrinque circiter 6-12. Flores in uno ramo abbreviato ad 
15-fasciculati, satis parvi (circiter 6 mm. diam.), flavi; pedicelli 
5-15 mm. longi; sepala interna obovata, petalis obovato-oblongis basi 
glanduliferis (nectaria in No. 2878 ut videtur minima) paullo majora, 
ovaria ovulis 1-2 sessilibus instructa. Fructus ovati, inflati, nigri,

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 Wén-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). 
This 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 Wén-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.
