Dicentra. FUMARIACE^. 95 



D. CucuUaria, DC. (Dutchman's Breeches.) Rather larger, with similar foliage; 

 tuberous-thickened subterranean leaf-bases angular, white or reddish, collected to form a 

 kind of scaly Heshy bulb: scape bearing several nodding flowers (in Oregon sometimes 

 paniculate) : corolla deciduous in fruiting, white with yellowish tips, divergently 2-spurred 

 at base, the spurs as long as the body and longer than the pedicel ; crest of inner petals 

 small, semioval, bladdery. — Syst. ii. 108 (Diclijtra) ; Hook. Fl. Bor.-Am. i. 35 (Dieltjtra);

 much shorter and rounded spurs) ; fl. spring. 



# * Inflorescence thyrsoid, subulate-bracteate, flowering for a long time, and the usually 

 rose-purple or flesh-colored cordate corolla withering-persistent around the fruit : tips of 

 the inner petals rather conspicuously crested on the back : glands of the filaments obso- 

 lete (stigma with a double pair of lobes in both species) : plants about a foot high from 

 rather stout and fleshy branching and spreading rootstalks: leaves once or twice ter- 

 nately compound and tlien quinately or pinnately dissected into rather coarse oblong and 

 incised divisions, usually green above, glaucescent beneath. — Eucapnos, Bernh. Linnrea, 

 viii. 468. 

 D, formosa, DC. Corolla cordate, and with very short neck under the short and ovate- 

 cymbiform spreading tips of the outer petals ; crests of inner petals little surpassing their 

 tips; all the petals united up to above the middle. — Syst. ii. 109 {Diclytra), excl. syn.

 D. eximia, DC. 1. c. (Didytra). Corolla tapering from the cordate base into a longer and 

 narrower neck, early separating to much below the middle ; lax tips of the outer petals

§ 2. Chrysocapnos, Torr. Caulescent and branching stout-rooted peren- 

 nials : inflorescence compound, thyrsoid-paniculate : corolla yellow, subterete, 

 deciduous ; outer petals barely gibbous at base, hardly larger than the inner : 

 stamens high-diadelphous : slender persistent style at dehiscence of the capsule 

 usually fissile up to the stigma into four portions, two answering to the valves 

 and two to the placentae : seeds crestless, the coat dull and rough.
