Kiangsi: Kuling, Temple of Wang Lung, planted, July 1907 

 (No. 1743; tree 26 m. tall, 6 m. girth). Western Hupeh: Ichang, 

 planted around temples and houses, alt. 30-1000 m., May and October 

 1907 (No. 2109; tree 20-30 m. tall, girth 3-6 m.). 



The Ginkgo is common as a cultivated tree in central and western China up to 

 an altitude of 1500 m. We never met with a spontaneous specimen and in our 

 opinion the tree no longer exists in a wild state. Masters (in Jour. Linn. Soc. 

 XXVI. 547 [1902]) states that Mrs. Bishop met with the Ginkgo in the forests 

 which surround the sources of the Great Gold River and the smaller Min, in west- 

 em China; and also in the forests of central Hokkaido, Japan. This is an error. 

 We have traversed the regions in western China cited by Mrs. Bishop and no 

 Ginkgo grows there. Cercidiphyllum japonicurriy var. sinense Rehder & Wilson is 

 common in that region and is colloquially known as the Peh-k'o tree, the name 

 which is generally applied all over China to the Ginkgo. We suspect Mrs. Bishop 

 was misled or confused and that the tree she saw and mistook for the Ginkgo was 

 the Cercidiphyllum. It is now known that the tree in the forests of Japan, Mrs. 

 Bishop took for the Ginkgo was Cercidiphyllum japonicvm Siebold & Zuccarini,
