Descurainia incana is a species of flowering plant in the mustard family known by the common name mountain tansymustard. It is native to much of North America, including most of Canada, the western United States, and Baja California. It is known from many types of habitat. It is a biennial herb with a slender, greenish, often hairy stem sometimes exceeding a meter tall. The leaves are narrowly to widely oval in shape, the lower ones lobed and sometimes compound, the upper generally unlobed. The mustardlike inflorescence is a series of developing fruits beneath an elongating cluster of small bright yellow flowers. The fruit is a thin, pointed silique up to 2 centimeters long.

06Genome at a glanceCCDB
The complete instruction manualDescurainia incana 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.

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.
