Antennaria racemosa is a species of flowering plant in the family Asteraceae known by the common name racemose pussytoes. It is native to western North America from British Columbia and Alberta south as far as northern California and Wyoming.US Forest Service Fire EcologyBiota of North America Program 2014 county distribution map It grows in mountain forests, generally in moist, partially shaded areas, and often colonizes bare patches of mineral-rich soil, including disturbed areas. Antennaria racemosa is a glandular perennial herb which may be small, woolly, and matted to nearly hairless and erect to heights near 50 cm (20 inches).Jepson Manual Treatment It forms basal patches of oval-shaped leaves 3 to 10 centimeters long, fuzzy on the undersides and shiny green above. The patches are connected with stolons covered in leaves. The erect stem bears an inflorescence which can be shaped like a raceme and is often dense, especially in higher elevations, containing several flower heads. The species is dioecious, with male and female plants producing different types of flowers in the heads.Flora of North America The fruit is an achene with a body only about a millimeter long attached to a soft pappus up to 7 millimeters long. The pappus catches the wind, which disperses the seed. The plant also reproduces vegetatively via its creeping stolons.

The complete instruction manualAntennaria racemosa 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.
