1924| REHDER, LIGNEOUS PLANTS OF NORTHERN CHINA, II 207 



Chili: Kalgan, on Mt. Gulick, N. E. Cowdry, no. 1843, July 7, 1921; 

 Po hua shan ("Ipe hoa chan"), A. David, no. 2248 (ex Franchet, 1. c). 



This Rose differs at the first glance strikingly from typical R. bella in 

 its very small leaflets pubescent beneath and occasionally 11 in number, 

 but in Meyer's no. 1239 from Hsiao Wu tai shan part of the leaves on one 

 of the branches have the leaflets as small and pubescent beneath, though 

 they are never more than 9-foliolate, and Cowdry's no. 1974 from Kalgan 

 has also rather small leaflets 1-2 cm. long, Cowdry's no. 1843 agrees well 

 with Franchet's description but the leaflets can hardly be called doubly 

 serrate, though the teeth have occasionally on some leaves more often 

 than on others a minute tooth on one side.

 Rehder & Wilson in Sargent, PL Wilson, n. 324 (1915). 



Shensi: Lung chow, Li kia po, alt. 1400 m., J. Hers, no. 2384, July 4, 

 1922. 



Kansu: Min chow district, alt. 3000 m., W . Purdom, no. 1059, 1910; 

 without precise locality, W. Purdom, no. 1143, 1910. — See also Rehder 

 & Wilson, 1. c. 



Distribution: also Szechuan. 



The original description of this species was based on cultivated plants 

 raised from seed supposed to have been collected in Kansu; the subsequent 

 discovery of the plant in Kansu shows that this supposition was correct. 



Rosa Biondii Crepin in Bull. Soc. Bot. Ital. 1897, 233. 



Shensi: "Gniu-ju," G. Giraldi, no. 47 (ex Crepin, 1. c). 



Kansu: Min chow, alt. 2600 m., W. Purdom, no. 1144, 1910. 



I refer Purdom's material with some doubt to R. Biondii of which I have 

 seen no specimen; it agrees fairly well with Crepin's description although 

 the bracts at the base of the pedicels arc rather narrow, not "tres dilutees" 

 as described by Crepin, and the number of leaflets is 7 or 9, very rarely 

 5, not 5 or 7. In the narrow stipules it agrees with R. MurielaeTlehdtiT & 



Wilson, but that species has more numerous and smaller leaflets and an 

 inflorescence of usually several flowers. 



Possibly identical with one of the four preceding species and probably 

 with R. bella is the undescribed R. Przewalskii Regel ined. apud Bret- 

 schneider (Hist. Eur. Bot. Discov. China, 975, 1053 [1898], nomen) col- 

 lected by Przewalski in 1880 on the Djakhar Mountain, south of Kui 

 te, Kansu, and by Bretschneider on the Peking mountains. According 

 to Bretschneider there is a note by Crepin on the label stating that it 

 seems a form of R. macrophylla Lindl.
