2 WILSON EXPEDITION TO CHINA 



The Chinese name " Peh-k'o " signifies white nut. The seeds after roafting 

 are eaten by the Chinese and much esteemed. In the late autumn the leaves of 

 the Ginkgo assume a beautiful yellow color and the trees are in consequence most 

 conspicuous objects at this season. Occasionally in old specimens large, ovoid 

 protuberances, covered with thick bark and a foot or more long, grow out and down- 

 wards from the larger branches. This phenomenon is, however, rare as far as our 

 observations go. 



Pictures of this tree will be found under Nos. 51, 260, 335, 387, 388, 439 of the 

 collection of Wilson's photographs and also in his Vegetation of Western China, 

 Nos. 229, 230, 231, 232.
