01Narrative

Strumaria truncata is a species of flowering plant in the family Amaryllidaceae, native to the Cape Provinces of South Africa. It is widely distributed in the northwest of the Cape Provinces, and the most common of the Strumaria species found there. It forms small clumps of bulbs which produce twisted leaves. Its flowers, which are pendulous, vary in colour from white to deep pink. The pink forms were once treated as a separate species, Strumaria rubella, and have also been called var. rubella. The species was first described by Nikolaus Joseph von Jacquin in 1792.

05DNA & barcoding4 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 Strumaria truncata has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Strumaria truncata 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 DNA4 detections

Where the DNA of Strumaria truncata 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 strong is each trace?

DNA read depthRead counts were not reported for this species — the map shows presence only, not how strong each trace was.

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.
