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 inonadelphous 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 Major J. Adlum, amateur botanist.) 



1. A. fungdsa (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 

 tushes ; often cultivated, and frequently escaping. 



2. DICENTRA Bernh.

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

 Filaments slightly united into 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 5/s, twice, and nlvrpov, a spur ; accidentally printed DICLYTRA in the first 

 instance, which by an erroneous conjecture was changed afterwards into

 (Sicuculla 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. canad&nsis (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. (Sicuculla Millsp.) 

 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 the 

 inner petals projecting. (Sicuculla Millsp.) Rocks, w. N. Y., rare, and
