 DICENTRA Bernh. Linnsea, viii, 557, 468. 



Smooth perennials with tuberiferous or granuliferous subter- 

 ranean base, or running rootstocks, ternately or pinnately com- 

 pound leaves and racemous or paniculate flowers. Sepals 2, 

 small and scale-like. Corolla flattened and cordate, at least at 

 base, of two pairs of petals,, the outer pair larger, saccate or 

 spurred at base, the tips spreading; the inner much narrower, 

 spoon-shaped, mostly carinate or crested on the back ; the small 

 hollowed tips slightly united at the apex, the two forming a cavity 

 which contains the anthers and stigma. Stamens 6, in two sets ;

 ma 2-lobed ; .each lobe sometimes 2-crested or horned. Capsule

 s pan to a foot or more high : leaves twice or thrice ternately compound, 

 the ultimate divisions narrow and incisely pinnatifid : flowers in compound 

 r acemes at the summit of the naked scapes : corollas ovate-cordate with 

 r ounded somewhat connivent spurs and short spreading tips to the larger
