 scholtzia calif ornica). a, flower; b, fruit 

 before, and, c, after dehiscence. The juice 

 of this plant is a valuable soporific. (After 

 Strasburger, Noll, Schenck and Schimper). 



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

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

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

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

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

 tuberosa) contains eight alkaloides; of which corydalin C 22 H 27 NO 4 is the most 

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

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

 corydalin. Schlotterbeck and Watkins found 5 alkaloids in the American 

 celandine (Stylophorum diphyllum) among them chelidonin C 00 H 19 NO 5 +H 2 O. 

 The alkaloids stylopin C 19 H J9 NO 5 , protopin C 20 H 19 NO 5 , and sanguinarin, 

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