1924] REHDER, LIGNEOUS PLANTS OF NORTHERN CHINA, II 199 



Shansi: Wu chai hsien, Ta nan kow, alt. 2000-3000 m., Tchuang Kieh, 

 Hers no. 2016, September 7, 1922. 



Distribution: also Europe, Northern Asia. 



The specimens cited above do not seem to differ from typical R. Idaeus; 

 of R. idaeus var. strigosus which occurs in Manchuria, Korea and Japan, 

 I have seen no specimen from northern China and I have found no record 

 except the following. 



Rubus idaeus @. strigosus Maximowicz in Bull. Acad. Sci. St. Petersb. 

 xvn. 161 (1872); in Mel. Biol vm. 394 (1872).— Palibin in Act. Hort. 

 Petrop. xiv. 116 (1895). 



Chili: Weichang (ex Palibin, 1. c). 



Distribution: Manchuria, Korea, Japan; also in North America. 



Rubvs acuminatissimus Hasskarl ? var. kansuensis Kanitz in Szechenyi, 

 Keletazs. Utjdn. Tudom. Ered. n. 847 (PI. Enum. 21) (1891) ; in Szechenyi, 

 Wiss. Ergeb. Reise Ostas. n. 697 (1898). 



Kansu: "inter Wej-ho et Tsing-tchou," no. 155 (ex Kanitz, 1. c). 



This plant referred by Kanitz to the Javanese R. acuminatissimus I 

 am unable to place; it is not at all probable that a Kansu plant belongs 

 to a Javanese species and therefore I cannot consider Kanitz's determina- 

 tion as correct. I have seen no specimen of R. acuminatissimus Hasskarl, 

 but judging from the description I do not think it impossible that Kanitz 

 bad a specimen of R xanthocarpus Bur. & Francb. before him. 



There are three specimens collected by Hers, nos. 635, 1536 and 2714, 

 the first with young flower-buds, the others sterile, which are too incomplete 

 for determination. 



Potentilla fruticosa Linnaeus, Spec. 495 (1753). — Franchet in Nouv. 

 Arch. Mus. Paris, ser. 2, v. 262 (PL David. I. 110) (1883).— Hemsley in 

 Jour. Linn. Soc. xxm. 243 (1887). — Kanitz in Szechenyi, Keletazs. 

 Utjdn. Tudom. Ered. n. 809 (PL Enum. 21) (1891); in Szechenyi, Wiss. 

 Ergeb. Reise Ostas. n. 732 (1898).— Palibin in Act. Hort. Petrop. xiv. 

 117 (1895).— Pritzel in Bot. Jahrb. xxix. 402 (1900); xxxvi. beibl. lxxxii. 

 56 (1905).— Rehder & Wilson in Sargent, PL Wilson, n. 301 (1915). 

 Limpricht, Bot. Reis. Hochgeb. Chin. Ost-Tib. 407 (1922). 



Chili: Weichang, W. Purdom, no. 127, 1909. — See also Franchet, 1. c, 

 Hemsley, 1. c, Palibin, 1. c, Rehder & Wilson, 1. c, and Limpricht, 1. c. 



Shensi: several localities, G. Giraldi (ex Pritzel, 1. c). 



Kansu: ex Kanitz, 1. c. 



Distribution: northern and central Asia, Europe, North America. 



It is doubtful if typical P. fruticosa occurs in northern China. The 

 only specimen cited above has the glabrate leaves of var. davurica but 

 the shape of the outer sepals is too narrow and the color of the flowers 

 is not recognizable with certainty. 



The specimens enumerated under P. fruticosa by the authors quoted 

 above are probably referable to different varieties.
