Le lierre du Cap, également connu sous le nom de séneçon rampant, est une plante succulente à fleurs de la famille des Asteraceae, originaire d'Afrique du Sud. Le lierre du Cap est une plante qui peut devenir une mauvaise herbe agressive une fois établie, ce qui en fait une espèce envahissante. Elle est cultivée comme plante ornementale pour son feuillage satiné et ses fleurs au parfum sucré. D'autres noms communs incluent le séneçon grimpant, le senecio incliné, le senecio algérien, le séneçon angulaire, le senecio jordanien et le séneçon brouillant. C'est une mauvaise herbe problématique en Nouvelle-Zélande. Elle est naturalisée dans certaines parties de l'Afrique du Nord et du sud de l'Europe.

03Chemical composition7 compounds
Compounds documented for Senecio angulatus 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 Senecio angulatus has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualSenecio angulatus 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.

09Environmental DNA3 detections
Where the DNA of Senecio angulatus 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.
