456 FLORA. 



tubcrcled, jointed. Leaves 5-13 cm. broad, those of the stem generally 3 and ap- 

 proximate or verticillate, 3-parted nearly to the base; divisions lanceolate, linear 

 or oblong, the lateral ones often deeply 2-cleft, all incisely toothed or lobed; basal 

 leaves similar, rarely developed at flowering time; pedicels ascending, stout, 1.5-2 

 cm. long in fruit; flowers 1. 4-2 cm. broad, white or pink; pods linear, ascending, 

 2-4 cm. long; style 6-8 mm. long. In moist or rich woods, Quebec to Fla., Minn., 

 Kans. and La. April -June. 



2. Dentaria diphylla Michx. Two-leaved Toothwort. (I. F. f. 1736.) 

 Stout, scapose, glabrous, 2-4 dm. high; rootstock continuous, toothed. Basal 

 leaves long-petioled, I-I.3 dm. broad, ternate, the divisions short-stalked, broadly 

 ovate, dentate, or somewhat lobed, about 5 cm. long; stem-leaves generally 2, op- 

 posite or nearly so; pedicels 2-4 cm. long; flowers white, 1.4-1.6 cm. broad; peds 

 2.5 cm. long or more. In rich woods and meadows, N. S. to Minn., S. Car. and 

 Ky. May. 



3. Dentaria maxima Nutt. Large Toothwort. (I. F. f. 1737.) Similar 

 to the preceding but larger; rootstock jointed, tubercled. Stem-leaves 2-7 (gen- 

 erally 3), alternate, similar to the basal ones; flowers pale purple, 1.5-2 cm. 

 broad. Vt. to N. Y. and Penn. May. 



4. Dentaria heterophylla Nutt. Slender Toothwort. (I. F. f. 1738.) 

 Slender, glabrous or somewhat pubescent, 2.5-3.5 am - high; rootstock jointed. 

 Basal leaves long-petioled, ternate; divisions ovate, the terminal one cuneate or 

 rounded at the base, the lateral ones inequilateral, the lobes or teeth mucronate; 

 stem-leaves generally 2, opposite or nearly so, ternate, the divisions linear or lan- 

 ceolate; pedicels 2.5 cm. long in fruit; flowers light purple, 1. 6-1. 8 cm. broad; pods 

 ascending, 2.5 cm. long. In woods, N. J. and Penn. to Ga. and Tenn. April- 

 May. 



21. LUNARIA L. 



Pubescent erect herbs, with broad dentate or denticulate mostly cordate leaves, 

 and large violet flowers in terminal racemes. Lateral sepals saccate at the base. 

 Petals obovate, clawed. Siliques long-stipitate, very flat, oblong or elliptic, dehis- 

 cent, the papery valves reticulate- veined. Style filiform; septum hyaline, trans- 

 lucent, shining. Seeds circular or reniform, very large, winged, borne on long 

 funiculi, which are adnate to the septum; cotyledons large, accumbent. [Latin, 

 moon, in allusion to the shining partition of the pod.] Two known species, natives 

 of Europe and Asia. 



Siliques oblong, pointed at both ends ; perennial. 1. L. rediviva. 



Siliques elliptic, rounded at both ends; annual or biennial. 2. L. atmua. 



i. Lunaria rediviva L. Perennial Satin-pod or Satin-flower. (I. F. f. 

 1739.) Pubescent with short simple hairs; stem 3-12 dm. tall. Leaves broadly 

 ovate, acuminate at the apex, cordate or rounded at the base, thin, the lower long- 

 petioled, 0.7-1.5 dm. long; flowers 1.5-2.5 cm. broad, slender-pedicelled; pods 

 oblong, 5-8 mm. long, drooping, borne on slender stipes of about one-half their 

 length; seeds reniform, broader than long. In thickets, Canadian side of Niagara 

 Falls. Escaped from gardens or fugitive from Europe. May-July. 



2 Lunaria annua L. Honesty. (I. F. f. 1740.) Resembles the preceding 

 species when in flower, but the root is annual or biennial. Siliques elliptic or 

 broadly oval, 3-5 cm. long, 2.5 cm. wide or rather more, rounded at both ends; seeds 

 sul orbicular, cordate, about as long as wide. Escaped from gardens to roadsides 

 in southwestern Connecticut. Both this species and the preceding are occasionally 

 cultivated for their remarkably large pods, which are gathered for dry bouquets, 

 the valves falling away at maturity and leaving the septum as a shining membrane. 

 May-June. 



22. SELENIA Nutt. 



Annual tufted glabrous herbs, with pinnatisect leaves, and racemose leafy- 

 bracted yellow flowers. Sepals spreading. Petals narrow, erect, with 10 hvpogy- 

 nous glands at their bases. Silique -talked, very flat, oblong, narrowed at each 

 end, dehiscent; valves nerveless, thin, finely veined. Style long, slender. Seeds
