570 WILSON EXPEDITION TO CHINA 



The flowers, shoots and under surface of the leaves of this plant are covered 

 with a fulvous-gray, rather loose tomentum which readily distinguishes this 

 variety from the type.^

Western Szeeh'uan: Wa-shan, thickets, alt. 1300-2000 m., 

 August 1908 (No. 3358; bush 1.5-2.5 m. tall, flowers purple); south- 

 east of Tachien-lu, Tung valley, alt. 1300-2000 m., August 1908 (No. 

 3356; bush 1-1.5 m. tall, flowers hlac purple); Wa-shan, alt. 2000- 

 2600 m., July 1903 (Veitch Exped. No. 4121 and seed No. 1428, 

 type). 



A rather rare plant. Duthie describes the calyx as one-third the length of 

 the corolla-tube, whereas, as shown in the figure accompanying his description, it 

 is half as long as the corolla-tube.

Western Szeeh'uan: without precise locaUty, in a ravine, alt. 1300 m., 

 August 1903 (Veitch Exped. No. 4118). 



Buddleia alata differs from all the aUied species in its four- winged stems. It seems 

 most nearly related to B. albiflora Hemsley, which is, however, easily distinguished 

 by its glabrous or glabrescent corolla, by the glabrous ovary, shorter style and by 

 the subterete stems.
