La mélique élevée ou mélique de Sibérie est une espèce de plantes herbacées de la famille des Poaceae (graminées) originaire de Sibérie. Elle pousse facilement sur sols arides et pauvres. Sa panicule est très rameuse, imitant celle des avoines. Elle est très vigoureuse et précoce. Ses tiges nombreuses et droites peuvent mesurer jusqu'à un mètre de haut.

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 Melica altissima has left across the world's sequence archives.

Melica altissima voucher 3306HIM internal transcribed spacer 2 and large subunit ribosomal RNA gene, partial sequence
Marker genes sequenced
★ 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 manualMelica altissima 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.
