1924| REHDER, LIGNEOUS PLANTS OF NORTHERN CHINA, II 185 



Distribution: its native country is supposed to be Persia and Turkestan. 



The Quince seems to be very little cultivated in China and apparently 

 only in the northern provinces. It has been recorded from Shantung 

 and Honan and Debeaux states that it is also found in Chili; he remarks 

 that the fruits are much smaller than those of the plant of southern 

 Europe, while Gilg and Loesener state that it has according to Nebel 

 very large fruits. The fruit sent by Mr. Hers from Honan is pear-shaped 

 and about 5 cm. long. There is also a specimen in the herbarium of 

 this Arboretum from Kiangsu, collected near Nanking (Herb. Univ. 

 Nanking, no. 371), this, too, is without doubt from a cultivated plant. 

 Whether Purdom's Shensi specimen is from a cultivated or a wild plant 

 is unfortunately not stated and there is still a possibility that the Quince 

 may be a native of China and that it is only cultivated and naturalized 

 in central and western Asia now supposed to be its native country, but 

 the evidence we have so far is not yet convincing. In Chinese literature 

 it seems to be confused with the Chinese Quince (Chaenomeles sinensis 

 Koehne), though Hers states in the label to his no. 838 that it is called 

 by the Chinese "mu li," while the Chinese Quince is called "mu kua li."

Chili: Peking, cultivated (ex Bunge, 1. c., and Hemsley, 1. c). 



Shantung: Pearl mountains, 0. Nebel (ex Loesener, 1. c.); Nan shan 

 near Chifu, ? cultivated (ex Ito, 1. c). 



Honan: without special locality, cultivated (ex Hers, 1. c). 



Shensi: Tsin ling shan, A. David (ex Franchet, 1. c, Hemsley, 1. c, 

 and Pritzel, 1. c). 



Kansu: Tsing chow, alt. 1400 m., J. Hers, no. 2409, July 21, 1922

Distribution (including the varieties): also Hupeh and Szechuan. 



The type probably occurs wild on the Tsin ling shan range in Shensi 

 and eastern Kansu and is cultivated elsewhere. The var. cathayensis 

 Rehd. grows spontaneously in Hupeh and the following variety in Sze- 

 chuan and Kansu.
