Avena est un genre de plantes monocotylédones de la famille des Poaceae, sous-famille des Pooideae. Ce genre comprend une trentaine d'espèces originaires des régions tempérées de l'Ancien Monde. Ce sont des plantes herbacées annuelles ou vivaces, cespiteuses ou décombantes, dont les tiges (chaumes), non ramifiées, peuvent atteindre de 20 à 200 cm de long. L'inflorescence est une panicule ouverte, lâche.

Compounds documented for Avena across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Avena has left across the world's sequence archives.

09Environmental DNA1 detections
Where the DNA of Avena 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 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.
