cinalis Linn, and S. canadensis Linn., the present material 
matching specimens from various parts of China, some identified 
as S. officinalis Linn, and some as S. canadensis Linn. The 
Kwangtung material closely matches European material of S. 
officinalis Linn., and I assume this name to be correct for it. 
Sanguisorba formosana Hayata, as represented by Formosan 
material, Kawakami 93, is scarcely to be distinguished.
