♦ Corolla bijfiblious or '2-spiiiTefl, 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 ariled seeds. 



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



1. ADLtrMIA Raf. Climbing Fumitory 



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

 cellular and persistent, inclosing 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 to 3Iajor J. Adhim, amateur botanist.) 



1. A. fung5sa (Ait.) Greene. — Wet or recently burned woods; e. Que. to 

 Ont., Wise, and s. in the mts. to N. C. June-Oct. (A. cirrhosa Raf.) — 

 Handsome delicate vine climbing by the slender young leaf-stalks over high 

 Pushes ; often cultivated, and frequently escaping. 



2. DICENTRA Bernb. 



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

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

 Filaments slightly united into two sets. Pod 10-20-seeded. Seeds created. — 

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

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

 from 5is, twice, and Kevrpov, a spur ; ■ — accidentally printed Diclttra in the first 

 instance, which by an erroneous conjecture was changed afterwards into 



DiELYTRA.) BiKDKULLA AdaUS. BiCUCULLA MiUsp. 



* Raceme simple^ few-Jloicered. 



1. D. Cucullaria (L.) Bemh. (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. 

 {Bicuculla Millsp.) — Rich woods, N. S. to L. Huron and Minn., s. to N. C. 

 and Mo. — 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. canadensis (Goldie) Walp. (Squirrel Corn.) Subterranean shoots 

 bearing scattered grain-like tubers (resembling peas or grains of Indian corn, 

 yellow); leaves as in no. 1 ; corolla merely heart-shaped, the spurs very short and 

 rounded; crest of the inner petals conspicuous, projecting. {Bicuculla Mill;3p.) 

 — Rich woods, N. S. to Ont. and Minn., s. to Va., Ky., and Mo. Apr., May. — 

 Flowers greenish white tinged with rose, with the fragrance of hyacinths. 



* * Racemes compound, clustered. 



3. D. eximia (Ker) Torr. Subterranean shoots scaly ; divisions and lobes 

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

 inner petals iDrojecting. (Bicuculla Millsp.) — Hocks, w. N.Y., rare, and 

 southw. along the Alleghenies. May-Aug. — Coarser-leaved than the others: 

 scapes 1.5-2.5 dm. high. 



3. CORYDALIS [Dill.] Medic. 



Corolla 1-spurred at the base (on the upper side), deciduous. Stj'le per- 

 sistent. Pod many-seeded. Seeds crested or ariled. Flowers in racemes.
