1923] REHDER, THE LIGNEOUS PLANTS OF NORTHERN CHINA 153 



Shensi : Kin qua san, G. Giraldi, July 10, 1897; Tai pei shan, W. Purdom, 

 no. 998, 1910; Kwan yin tang, F. N. Meyer, no. 2015, September 15, 

 1914; Pai hsi pa, F. N. Meyer, no. 1938, September 18, 1914 (Herb. U. S. 

 Dept. Agric.). — See also Burkill, 1. c, Diels, 1. c, Schneider, 1. c. 



Kansu: Dshoni River, G. N. Potanin (ex Burkill, 1. c.); Lan tschan 

 south of the Hoangho, P. J. Piasezki (ex Maximowicz, 1. c. and ex Burkill, 

 I.e.) 



Distribution: also Kiangsu (Hers, nos. 652, 2278), Hupeh, Szechuan, 

 Kweichou (Handel-Mazzetti, no. 10331), Hunan, Kiangsi. 



Burkill refers the specimen from Shensi and Kansu to the typical form, 

 but as the Shensi specimens I have seen belong to this variety I assume 

 that the range of typical C. heterophylla does not extend much beyond Chili 

 and that in western China it is replaced by var. sutchuenensis .

Shensi: Lung chow, Li kia po, alt. 1400 m., J. Hers, no. 2389, July 4, 

 1922 (sterile). 



Distribution: also northwestern Szechuan; Manchuria, Korea, Japan. 

 As the Shensi specimen is sterile, I am not absolutely certain if it belongs 

 here or perhaps to the preceding species. 



To one of the two preceding species belong probably also sterile speci- 

 mens of Corylus spec, collected in Shantung on the Lau shan (see Loesener, 

 Beih. Bot. Centralbl. xxxvu. abt. II. 107 [1919]).
