01Narrative

L'Eriocephalus africanus est une espèce de plante à fleurs originaire d'Afrique du Sud. Il est présent en quantité dans l'ouest et l'est de la région floristique du Cap et au Namaqualand. La plante a plusieurs noms vulgaires dans diverses langues : Cape Snow Bush, Kapokbossie, Wild rosemary, African rosemary… L'apparence de son feuillage, bien que plus lisse et plus mat, le fait ressembler superficiellement au romarin de Méditerranée, quoique les deux n'aient rien en commun.

05DNA & barcoding3 specimens

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 Eriocephalus africanus has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Eriocephalus africanus 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. Click any value below to see the underlying records and sources.

09Environmental DNA4 detections

Where the DNA of Eriocephalus africanus 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.
