 PI Formos.) (1906). 



Lysionotus warleyensis Willmott in Gard. Chron. ser. 3, LIV. 125 (1913). 



Western Hupeh: Hsing-shan Hsien, cliffs, alt. 1200-1500 m., 

 July and October 1907 (No. 370; flowers creamy white, spotted pur- 

 ple); Changyang Hsien, cliffs, alt. 600-900 m., July 1907 (No. 3519; 

 flowers purple); without precise locality, A. Henry (No. 6139). 



I have not been able to compare flowering specimens of the Japanese plant, 

 but a co-type in fruit in the Gray Herbarium of Maximowicz's species agrees very 

 well with the Hupeh plant; the capsules are identical with those of Wilson's No. 

 370, and the leaves do not differ from those of Wilson's No. 3519, while the leaves of 

 No. 370 are smaller and narrower, mostly hnear-oblong in outline and up to 3.5 cm. 

 long and to 7 mm. wide; the leaves of Henry's No. 6139 are similar, but somewhat 

 shorter and broader. The color of the flowers varies apparently from white and 

 spotted or striped purple to purple, as appears from Wilson's field notes.
