According to the Lower Hudson Prism: "Corydalis incisa, or Incised Fumewort, is an East Asian member of the Fumariaceae family so far only known from a few counties in New York, Pennsylvania, Maryland, Virginia and the Discrict of Columbia. The species is highly fertile and reproduces by seed explosively ejected from the fruit.

Incised fumewort currently occupies hundreds of acres along both banks of the River and is especially dense in the Bronx River Forest, just north of The New York Botanical Garden.

It’s an imported plant with no natural enemies or competitors.
