Question
Found in a cow pasture in Edgartown. Siliques up to two cm long with two rows of seeds. Plants up to about 3' tall. Stems with very fine pubescence. Tap root.
Answer
Dear gregorypalermo, Your plant is likely Descurainia sophia (fine-leaved tansy-mustard), a species with finely divided leaves as you have photographed. This species is known from human-disturbed habitats here and there throughout New England.
