Japanese specimens named R. pulcher, Linn., by Mr. Franchet 
and Mr. Maximowiez we think may be this species; but without 
very complete specimens the two species are sometimes difficult

probably R. dentatus, Linn., but it is in an early flowering stage. 
His Chinese collector called it Ta Huang (rhubarb), and stated 
that it is the kind used as a cooling medicine, that it is wild on 
the borders of fields, and that it is sometimes cultivated.
