Antennaria luzuloides is a North American species of flowering plant in the family Asteraceae known by the common name rush pussytoes. The species is native to western Canada (Alberta, British Columbia) and the western United States (Oregon, Washington, northern California, Idaho, Montana, Nevada, Utah, Colorado, Wyoming, and a few isolated populations in South Dakota).Biota of North America Program 2014 county distribution mapCalflora taxon report, University of California, Antennaria luzuloides Torrey & A. Gray rush pussytoes, silvery brown pussytoes Antennaria luzuloides is a perennial herb growing greenish white or gray erect stems from a small woody caudex. It reaches a maximum height of about 25 centimeters. There is a basal patch of grayish woolly leaves each a few centimeters long and linear in shape to somewhat spoon-shaped. The inflorescence holds up to 30 rounded flower heads each less than a centimeter wide. The head is lined with narrow, pointed phyllaries. The species is dioecious, with male and female plants producing different flower types. The fruit is an achene up to about 6 millimeters in length including a long, soft pappus.Flora of North America Vol. 19, 20 and 21 Page 397 Rush or silvery brown pussytoes, Antennaria luzuloides Torrey & A.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Antennaria luzuloides has left across the world's sequence archives.

The complete instruction manualAntennaria luzuloides 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 luzuloides 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 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.
