184 WILSON EXPEDITION TO CHINA 



glabri leviter angulata; fructus alis orbiculari-ovatis apice rotundatis 

 2 cm. longis et 2-2.5 cm. latis glandulis fuscis nitentibus conspersis. 



Western Szech'uan: Wa-shan, alt. 1600 m., September 18, 

 1908 (No. 3212). 



This is a very distinct species, differing in its covered winter-buds from all others 

 known except the Japanese P. rhoifolia Siebold & Zuccarini. We have seen no 

 staminate flowers, but we are convinced that the staminate aments described by 

 Franchet under P. Paliurus belong here, as they agree in regard to their position 

 exactly with those of P. rhoifolia, which is closely related to P. insignis. The 

 Japanese species is well distinguished by its smaller more numerous leaflets mark- 

 edly lepidote-glandular below, its sparsely pubescent axis of the fruit-catkin and 

 by its much smaller wings (1.2 cm. long, 1.6 cm. wide) to the fruit. 



This new Pterocarya is a rare tree and known to us from only one locality near 

 the base of Mt. Wa. A picture of this tree will be found under No. 355 of the col- 

 lection of Wilson's photographs and in his Vegetation oj Western China, No. 412.
