Iris laevigata, known as Japanese iris, rabbit-ear iris, or shallow-flowered iris (Japanese: ' カキツバタ), is a species of flowering plant in the family Iridaceae, native to Japan. It is related to other members of Iris subgenus Limniris, including other species of Japanese irises. It is found growing in shallow waters and seems to prefer marshy and still ponds, although it can also be grown in damp soil if conditions are right. Flowers are usually blue, purple or violet and have unique colour patterns including some types with predominantly white flowers with blue spots (washino-o), and dark purples bordered with white (maikujaku). Synonyms include I. albopurpurea and I. phragmitetorum.

06Genome at a glanceCCDB
The complete instruction manualIris laevigata 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.

09Environmental DNA12 detections
Where the DNA of Iris laevigata 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.
