Botanical Name
Corydalis incisa (Thunb.) Pers.
Common Name
Incised Fumewort, Purple Keman
Flora of Virginia Name/Status
Not in Flora of Virginia (discovered after its publication).
This Asiatic biennial appears to be a shade-tolerant, aggressive invader that does well in mesic, forested habitats. See Atha, Schuler, and Tobing's paper in Phytoneuron 2014-96:1-6 for details about this species occurrence in New York. Recent reports of Corydalis incisa from North Carolina suggest that this species may be starting to escape, at least locally, over a considerable range in the eastern US.
Shaded yards and mesic forests, especially along and near streams. As of April 2018, the species is known from two localities in and near the city of Charlottesville; Pocahontas State Park (Chesterfield Co.); along the Maury River at Lexington; and two localities in Fairfax County. Experience suggests that the species is likely occurring undetected at additional sites.
