B. Two-Leaved Toothwort Or Crinkleroot - Dentaria diphylla
The Large Toothwort (Dentaria maxima Nuttall) has a jointed rootstock and three stem leaves (sometimes two or as many as five or six), alternate, with ovate and obovate toothed and cleft leaflets and large pale-purple flowers. It is rare and local in distribution.
The species of Dentaria are members of the Mustard family (Cruciferae) which contains a very large number of small-flowered, inconspicuous plants, many of them weeds, as well as a number of cultivated species which have become naturalized or established throughout the State.
