Sporobolus flexuosus is a species of grass known by the common name mesa dropseed. It is native to western North America, where it can be found in the deserts and woodlands of the Southwestern United States and Northern Mexico. This bunchgrass forms a tuft of stems growing up to 1 m long, erect to decumbent in form. It is a perennial grass but it is short-lived and is sometimes an annual.US Forest Service Fire Ecology The leaves are up to 26 cm long and rough-haired along the margins. The inflorescence is an open panicle of spreading branches bearing grayish spikelets.

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 Sporobolus flexuosus has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualSporobolus flexuosus 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 DNA1 detections
Where the DNA of Sporobolus flexuosus 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.
