Part 25 (1/2)

Sepals 2 or 3, often p.r.i.c.kly. Petals 4--6. Style almost none; stigmas 3--6, radiate. Pod oblong, p.r.i.c.kly, opening by 3--6 valves at the top.

Seeds crested.--Annuals or biennials, with p.r.i.c.kly bristles and yellow juice. Leaves sessile, sinuate-lobed, and with p.r.i.c.kly teeth, often blotched with white. Flower-buds erect, short-peduncled. (Name from ???ea, a disease of the eye, for which the juice of a plant so called by the Greeks was a supposed remedy.)

1. A. platceras, Link & Otto. Setose-hispid all over; petals white, 1--2' long; capsule armed with stout spines.--Central Kan. and Neb., south and westward.

A. MEXICaNA, L. (MEXICAN P.) Flowers yellow, rarely white.--Waste places, southward. July--Oct. (Adv. from trop. Amer.) (Addendum)--ARGEMONE MEXICANA. Collected at Merodosia, Ill., with white flowers, by _A. B. Seymour_.

ORDER 9. FUMARIaCEae. (FUMITORY FAMILY.)

_Delicate smooth herbs, with watery juice, compound dissected leaves, irregular flowers, with 4 somewhat united petals, 6 diadelphous stamens, and 2-merous pods and seeds like those of the_ Poppy Family.--Sepals 2, small and scale-like. Corolla flattened, closed; the 4 petals in two pairs; the outer with spreading tips, and one or both of them spurred or saccate at the base; inner pair narrower, and their callous crested tips united over the stigma. Stamens in two sets of 3 each, placed opposite the larger petals, hypogynous; their filaments often united; middle anther of each set 2-celled, the lateral ones 1-celled. Pod 1-celled, either 1-seeded and indehiscent, or several-seeded with 2 parietal placentae and deciduous valves.--Leaves delicate, usually alternate, without stipules. Slightly bitter, innocent plants.

[*] 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. cirrhsa, Raf.--Wet woods; N. Eng. to Mich., E. Kan., and southward. 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 deciduous 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 d??, _twice_, and ???t???, _a spur_;--accidentally printed DICLTRA in the first instance, which by an erroneous conjecture was afterwards changed into DIeLYTRA.)

[*] _Raceme simple, few-flowered._

1. D. Cucullaria, DC. (DUTCHMAN'S BREECHES.) Scape and slender-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 cl.u.s.ter 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, DC. (SQUIRREL CORN.) Subterranean shoots bearing 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 northward. April, May.--Flowers greenish-white tinged with rose, with the fragrance of Hyacinths.

[*][*] _Racemes compound, cl.u.s.tered._

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.--Coa.r.s.er-leaved than the others; scapes 6--10' high.
