60 FUMARIACE^E. (FUMITORY FAMILY.) 



* Corolla bigibbous or 2-spurred, the 2 outer petals alike. Pod several-seeded. 

 1 Adlumia. Petals united into a spongy persistent subcordate corolla. Seeds crestless. 



2. Dicentra. Corolla cordate or 2-spurred at base, less united. Seeds crested. 



* * Corolla with but one petal spurred at base, deciduous. 



3. Corydalis. Pod with few to many crested or arilled seeds. 



4 Fumaria. Fruit a globular 1-seeded nutlet. Seed crestless. 



1. ADLUMIA, Raf. CLIMBING FUMITORY. 



Petals all permanently united in a cordate-ovate corolla, becoming spongy- 

 cellular and persistent, enclosing the small, few-seeded pod. Seeds not crested. 

 Stigma 2-crested. Filaments monadelphous below in a tube which is adherent 

 to the corolla, diadelphous at the summit. A climbing biennial, with thrice- 

 pinnate leaves, cut-lobed delicate leaflets, and ample panicles of drooping white 

 or purplish flowers. (Dedicated by Rafinesque to Major Adlum.) 



1 A. cirrh6sa, Raf. Wet woods ; N. Eng. to Wise., E. Kan., and south- 

 ward. June -Oct. A handsome vine, with delicate foliage, climbing by the 

 slender young leaf-stalks over high bushes ; often cultivated. 



2. DICENTRA, Borkh. DUTCHMAN'S BREECHES. 



Petals slightly cohering into a heart-shaped or 2-spurred corolla, either de- 

 ciduous or withering-persistent. Stigma 2-crested and sometimes 2-horned. 

 Filaments slightly united in two sets. Pod 10-20-seeded. Seeds crested. 

 Low, stemless perennials (as to our wild species) with ternately compound and 

 dissected leaves, and racemose nodding flowers. Pedicels 2-bracted. (Name 

 from Sis, twice, and Ktvrpov, a spur ; accidentally printed DICLYTRA in the 

 first instance, which by an erroneous conjecture was afterwards changed into 



DlELYTRA.) 



* Raceme simple, few-flowered. 



1. D. Cucullaria, DC. (DUTCHMAN'S BREECHES.) Scape and slen- 

 der-petioled leaves from a sort of granulate bulb ; lobes of leaves linear ; corolla 

 with 2 divergent spurs longer than the pedicel; crest of the inner petals minute. 

 Rich woods, especially westward. A very delicate plant, sending up in 

 early spring, from the cluster of grain-like tubers crowded together in the 

 form of a scaly bulb, the finely cut leaves and the slender scape, bearing 4-10 

 pretty, but odd, white flowers tipped with cream-color. 



2. D. Canad6nsis, DC. (SQUIRREL CORN.) Subterranean shoots bear- 

 ing scattered grain-like tubers (resembling peas or grains of Indian corn, yellow) ; 

 leaves as in n. 1 ; corolla merely heart-shaped, the spurs very short and rounded ; 

 crest of the inner petals conspicuous, projecting. Rich woods, especially north- 

 ward. April, May. Flowers greenish-white tinged with rose, with the fra- 

 grance of Hyacinths. 



* * Racemes compound, clustered. 



3. D. eximia, DC. Subterranean shoots scaly; divisions and lobes of 

 the leaves broadly oblong ; corolla oblong, 2-saccate at the base ; crest of the 

 inner petals projecting. Rocks, western N. Y., rare, and Alleghanies of Va. 

 May - Aug Coarser-leaved than the others; scapes 6-10' high.
