1924] REHDER, LIGNEOUS PLANTS OF NORTHERN CHINA, II 163 



Sci. St. Petersb. xix. 260 (1874). — Hemsley in Jour. Linn. Soc. xxm. 

 279 (1887).— Bretschneider, Hist. Eur. Bot. Discov. China, 1054 (1898). 



Chili: near Peking (ex Maximowicz, 1. c, Hemsley, 1. c, and Bret- 

 schneider, 1. c). 



Distribution: also Central Asia to Szechuan. 



I have seen no specimens from northern China and as Janczewski in 

 his monograph does not mention it from this region its occurrence there 

 seems doubtful. 



Ribes nigrum Linnaeus, Spec. 201 (1753). — Hance in Jour. Bot. xm. 



132 (1875).— Hemsley in Jour. Linn. Soc. xxm. 279 (1887). 



? Ribes pauciflorum "Bge. vel affinis" Janczewski in Bot. Jahrb. xxvi. beibl. 

 lxxxii. 51 (1905). 



Chili: Po hua shan, E. Bretschneider (ex Hance, 1. c, and Hemsley, 

 1. c). 



Shensi: Kan y shan in Lao y shan, G. Giraldi, no. 3776 (ex Janczewski, 

 1. c). 



Distribution: Europe and Siberia east to Irkutsk and Tomsk. 



I have seen no specimens of R. nigrum from northern China and it 

 seems doubtful whether this species is found there; Janczewski in his 

 monograph gives Siberia as the native country of R. nigrum var. pauci- 

 florum (Turcz.) Jancz., while typical R. nigrum is restricted to Europe #
