Western Szech'uan: banks of Min River, June 1903 (Veitch Exped. No. 

 3258; sub-shrub, 0.5 m.). 



This new species seems to be most closely related to H. patulum Thunberg 

 and particularly to its var. uralum Koehne, which differs chiefly in its more 

 shrubby habit, in the only shghtly two-edged, never four-angled branches, larger 

 and broader leaves, much larger flowers with suborbicular or broadly ovate 

 rounded sepals.
