Type in Manchuria and north-east China. 
Plants grown in this Arboretum from seeds collected south of Jehol by M 
Purdom seem indistinguishable from C. tubulosa Turczaninow which represents 
the type of the species, while all the other synonyms are referable to the var. 
Davidiana Hemsley. These seeds came from the locality where Staunton collected 
the specimen on which C. heracleaefolia De Candolle is founded. From the mass 
of material before us we are disposed to refer all the continental forms of this 
group to C. heracleaefolia De Candolle and its varieties, considering them all 
variations of one polymorphic, polygamous species. The Japanese C. stans Siebold 
& Zucearini (syn. C. Maximowiczii Decaisne, C. Lavallei Decaisne, C. Savatieri 
Decaisne) with its coarsely toothed and lobed leaves, loosely paniculate inflores- 
cence, small whitish flowers and glabrescent, shining, ovoid achenes, seems to us 
sufficiently distinct to be considered a species.
