01Narrative

in Bhuvanagiri, Andhra Pradesh Aerva lanata, the mountain knotgrass, is a woody, prostrate or succulent, perennial herb in the family Amaranthaceae, native to Asia, Africa. It has been included as occurring in Australia by the US government, but it is not recognised as occurring in Australia by any Australian state herbarium. The plant sometimes flowers in the first year. Aerva lanata is a common weed which grows wild everywhere in the plains of India. The root has a camphor-like aroma. The dried flowers which look like soft spikes, are sold under the commercial names Buikallan and Boor. It is one of the plants included in Dasapushpam, the ten sacred flowers of Kerala.

05DNA & barcoding35 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 Ouret lanata has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Ouret lanata 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.

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.
