Streptopus amplexifolius (twistedstalk, clasping twistedstalk, claspleaf twistedstalk, white twisted-stalk, or watermelon berry) is a species of flowering plant in the family Liliaceae, native to North America, Europe and Asia. It is a herbaceous perennial plant growing to 40–100 cm tall, with alternate, oblong-lanceolate leaves 5–14 cm long. The greenish-white flowers hang from axils on 1–2 cm thin kinked pedicels, each flower with six white tepals, 9–15 mm long. The plants leaves completely encircle the stem, and the stems have a kink at each leaf axil giving the plants stem a "twisted" and wiry appearance. The plants grow in a creeping habit in moist, dense undergrowth.Lamarck, Jean Baptiste Antoine Pierre de Monnet de & Candolle, Augustin Pyramus de. 1805. Flore Française.

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 Streptopus amplexifolius 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 Streptopus amplexifolius 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.

Cultivated / Captivenot free-living
A living individual in a botanical garden, zoo or nursery — cultivated or kept, not free-living.
Where the DNA of Streptopus amplexifolius 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
Where its DNA was found
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.
