Antennaria corymbosa is a North American species of flowering plants in the family Asteraceae known by the common names flat-top pussytoes or meadow pussytoes.Flora of North America Vol. 19, 20 and 21 Page 407 Flat-top or meadow pussytoes, Antennaria corymbosa E. E. Nelson It is native to western Canada (British Columbia, Alberta, Saskatchewan) and the Western United States south as far as Tulare County in California and Rio Arriba County in New Mexico. It grows in moist, cool areas such as mountain meadows and riverbanks. Most of the populations are found in the Rocky Mountains, the Cascades, and the Sierra Nevada.Biota of North America Program 2014 county distribution mapCalflora taxon report, University of California, Antennaria corymbosa E. Nelson MeadowPussytoes, flat top pussytoes, meadow pussytoes Antennaria corymbosa is a small perennial herb growing from a basal patch of thin, gray, woolly, spoon-shaped leaves one or two centimeters long. It produces several erect stems no more than 15 centimeters tall, each holding an inflorescence of several flower heads. It is dioecious, with male and female plants producing different types of flower heads, which are generally similar in appearance. Each head has a surface of dark-dotted white phyllaries and contains tiny individual flowers. Female flowers yield fruits which are achenes no more than a millimeter long, not counting the soft pappus of 3 or 4 millimeters.Nelson, Elias Emanuel 1899.

The complete instruction manualAntennaria corymbosa 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.

Where the DNA of Antennaria corymbosa 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.
