Danthonia intermedia is a species of grass known by the common names timber oatgrass, intermediate oatgrass, and mountain wild-oat grass. This clumping erect perennial grass is native to North America, where it is widespread across most of Canada and along the western United States into California. It is a plant of the plains as well as forested, mountainous, alpine environments. Danthonia intermedia in mountain meadow at 10000 ft The bunchgrass reaches about half a meter in height at maximum. Its leaves are short and mostly basal. Each inflorescence is a narrow cluster of up to about ten spikelets, each spikelet holding 3 to 6 florets. The flowers are cleistogamous, meaning they remain closed and pollinate themselves. This grass also sometimes undergoes apomixis, reproduction without fertilization. This independence of the need for pollination between individuals is one reason why this grass is so widespread and able to tolerate a variety of climates. This is a desirable grass for grazing land because it begins growing earlier in the spring than most other grasses, and it tolerates heavy grazing better than some other grasses because of its basal meristem, that is, new growth occurs low on the grass instead of on the tip where it can be chewed off. This grass is an indicator of ecological climax in many ecosystems.

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 intermedia has left across the world's sequence archives.
At a glance
★ 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 manual Danthonia intermedia 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 far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Danthonia intermedia 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.
Signal

How strong is each trace?
Modelled climatemodelled
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.
