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

06Genome at a glanceCCDB
The complete instruction manualCorydalis incisa carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Chromosomes & ploidyhow the DNA is packaged
2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants. Click any value below to see the underlying records and sources.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

DNA clock origin12.5 Ma TimeTree
When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Where the DNA of Corydalis incisa was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?
DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.
How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
