Isolepis carinata (syn. Scirpus koilolepis) is a species of flowering plant in the sedge family known by the common name keeled bulrush. It is native to North America, where it is mostly distributed around the southeastern United States; it can also be found on the California coast. It grows in many types of moist and wet habitat, including disturbed, cultivated, and landscaped areas. It is an annual herb producing clumps of slender, erect stems up to 25 centimeters tall. The inflorescence is a solitary spikelet just a few millimeters long, or a cluster of up to three spikelets. These are accompanied by a stiff bract which looks like an extension of the stem growing past the 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 Isolepis carinata has left across the world's sequence archives.

09Environmental DNA1 detections
Where the DNA of Isolepis carinata 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.
