fruit is dry, flattened so that the placentas are brought close against 

 one another ; it dehisces longitudinally by the separation of the 

 placentas from the valves, which either leave them entirely or 

 remain clinging to one. The seeds, naked or with an arillary crest, 

 are formed as in Corydalis. About twelve species 1 of Dicentra are 

 known, half American, half from Temperate Central and Eastern 

 Asia. They are perennials, often climbing ; the leaves are alternate 

 multisect ; the flowers are collected into terminal or leaf-opposed 

 simple racemes or racemes of cymes.

Adlumia cirrkosa, 2 a climber from North America, is a Dicentra with 

 conferruminate petals ; it is in no other respect different. 



Corydalii (tigs. 154-15S) may be denned as Dicentra with only 

 one petal prolonged above its base into a spur, sac, or gibbosity.
