Status

Incised Fumewort is native to Asia. It was first discovered as an escape from cultivation in New York in 2005. It is now known from several States on the East Coast including Maryland.

Description

Incised Fumewort should be compared to Drug Fumitory. Without flowers, it can be difficult to distinguish Incised Fumewort from other Papaveraceae. Plants with flowers and fruits can be confidently identified. The pink to purple flower color sets this species apart from other locally-occurring Papaveraceae except Drug Fumitory. Drug Fumitory has globose fruits while Incised Fumewort has elongate, flattened fruits.

Where To Find

Incised Fumewort can be found in disturbed habitats including flood plains, roadsides and along trails. It seems to be particularly common along the suburban corridor between Washington, D.C. and Baltimore. However, the range of this species is expanding rapidly.

(Thunb.) Pers.

Corydalis incisa, incised fumewort, is an annual or biennial herbaceous species of plant in the poppy family.[1] It is also known as purple keman or murasa-kike-man. Some authorities report it in the family Fumariaceae.[2] The wildflower is native to Japan, Korea, Taiwan, and China, found in forests, clearings, and irrigation channels.[3]

Description

[edit]

Corydalis incisa grows up to 2 feet (0.61 m) tall. The life cycle begins in spring when seeds germinate and grow into small rosettes supported by a tiny tuber. The leaves are compound and divided into 3 leaflets, and again into another 3 sub-leaflets that are lobed to serrated. The leaves go dormant for the summer and re-emerge directly from the tuber in the fall. They are evergreen throughout winter. Stems emerge in February and blooming occurs from March through early May. There are about 10 to 16 flowers per raceme. The fruits, which are oblong, pod-shaped capsules, form quickly. The first seeds disperse about three weeks after the first flowers. By early summer, the mature plants are dead. Corydalis incisa can be found in waterways, rock walls, disturbed areas, and "mesic and alluvial habitats".[4]

Invasive species

[edit]

Incised fumewort is an introduced species in the United States, with populations in New York, Pennsylvania, Maryland, Virginia, West Virginia, North Carolina, Tennessee, and the District of Columbia.[2][5] The first reported populations were found in Bronx and Westchester Counties in 2005 and 2014. The plant can readily escape cultivation; it spreads from seeds explosively ejected from the fruit. The seed contains an elaiosome, which attracts dispersing ants. Apparently thriving in fine alluvial sediments, Corydalis incisa forms dense stands, crowding out more desirable riparian understory plants.[2][3][6]
