An illustrated flora of the An illustrated flora of the northern United States, Canada and the British possessions : from Newfoundland to the parallel of the southern boundary of Virginia and from the Atlantic Ocean westward to the 102nd meridian ed2illustratedflo02brit Year: 1913 CRUCIFERAE. 2. Dentaria diphylla Michx. Two- leaved Toothvvort. Fig. 2094. D. diphylla Michx. Fl. Bor. Am. 2: 30. 1803. Cardamine diphylla Wood, Bot. &; Fl. 37. 1870. Stout, erect, simple, glabrous, 8'-i4' high; rootstock continuous, toothed. Basal leaves long-petioled, 4'-5' broad, ternate, the divisions short-stalked, broadly ovate, dentate, or some- what lobed, about 2' long; stem-leaves gen- erally 2, opposite or nearly so, similar, shorter petioled and sometimes slightly narrower, ovate or ovate-lanceolate; pedicels I'-iJ' long; flowers white, 6'-8' broad; pods i' long or more. In rich woods and meadows, Nova Scotia and New Brunswick to Minnesota, south to South Carolina and Kentucky. Crinkle-root. Trickle. Two-toothed pepper-root. May. Dentaria anomala Fames, known only from Connecticut, growing with this species and D. laciniata, is probably a hybrid between them. 3. Dentaria maxima Nutt. Large Tooth- wort. Fig. 2095. 6. 1818. Fl. 38. 1870. Glabrous, similar to the last species but larger; rootstock jointed, prominently tuber- cled. Stem-leaves 2-7 (generally 3), alternate, similar to the basal ones, their divisions short- stalked, ovate to obovate, toothed or cleft; flowers pale purple, 8'-io' broad. Maine to Michigan and Pennsylvania. Local. May., Dentaria incisifolia Fames, known only from Sherman, Connecticut, differs in having lanceo- late, incised-dentate sessile leaf-segments.
