326 WILSON EXPEDITION TO CHINA 



October 1908 (Nos. 3580, 35865 bush 2.5-5 m.; flowers pale rose color, 

 fruit scarlet) ; west and near Wen-ch'uan Hsien, thickets, alt. 2000- 

 2600 m., June, July and September 1908, October 1910 (Nos. 1062, 

 4028X; bush 4 m., flowers pale pink, fruit scarlet). 



This handsome Rose is abundant in the thickets and on the margin of woods 

 in the regions east of Tacliien-ln, where the type is common. With its large pale 

 pink flowers and large leaves this form looks very distinct from the type.
