 Strasburger, Noll, Schenck and Schimper). 



rhizome of the blood root is used in medicine and contains an alkaloid sangnin- 

 arin and a dye. The corydalin is found in a species of the genus Diccntra 

 The bleeding heart {Dicentra spectabilis), native to China, and the climbing 

 fumitory (Adlumia cirrlwsa) are frequently cultivated for ornamental purposes. 

 According to Blyth, the root of the tuberous-rooted corydalis (Corydalis 

 ttiberosa) contains eight alkaloides ; of which corydalin CjgH^.NO^ is the most 

 important, since, when taken in large doses it may cause epileptiform convul- 

 sions, death taking place from respiratory paralysis. The C. lutca contains 

 corydalin. Schlotterbeck and Watkins found 5 alkaloids in the American 

 celandine {Stylophorum diphyllum) among them cheiidonin C2QHjgN0,,+H,0. 

 The alkaloids stylopin Cj^^H^^NOj., protopin C^^H^gNO.., and sanguinarin, 

 have been in part found in other plants in the family.
