Stuckenia vaginata (syn. Potamogeton vaginatus), commonly called sheathed pondweed, big sheathed pondweed or large-sheathed pondweed is a water plant species that grows in fresh and brackish water in Europe, Northern Asia (excluding China) and North America. Sheathed pondweed is rare, but is not in the 2012 IUCN Red List. Stuckenia vaginata is a fully submerged aquatic plant and does not have any floating or emerged leaves. The flowers are wind pollinated and the seeds float. Tubers that are rich in starch are formed on the rhizomes. Reproduction can either be vegetative with tubers and plant fragments or sexual with seeds.

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 Stuckenia vaginata has left across the world's sequence archives.

The complete instruction manualStuckenia vaginata 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 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.
