Дантония однолистная — вид травы. Иногда растение рассматривают как разновидность Danthonia Californica, на которую он похож. Дантония однолистная родом из западной части Северной Америки, где растёт в нескольких типах среды обитания, включая луга и открытые участки горных лесов. Дантония однолистная — многолетняя трава, растущая пучками высотой от 10 до 30 сантиметров, с очень опушенными, скрученными листьями. Соцветие несёт один колосок, а иногда и до четырёх.

05DNA & barcoding19 specimens
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 Danthonia unispicata has left across the world's sequence archives.

The DNA barcodea real sequence read deposited for this species
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manualDanthonia unispicata 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 DNA6 detections
Where the DNA of Danthonia unispicata 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.
