Arnoglossum plantagineum also known as tuberous Indian-plantain, groovestem Indian plantainLady Bird Johnson Wildflower Center, University of Texas, Arnoglossum plantagineum Raf. Groovestem Indian plantain, Indian plantain, Prairie plantain, Prairie Indian plantain or Prairie Indian plantain,Illinois Wildflowers, Prairie Indian Plantain Arnoglossum plantagineum is a North American species of Arnoglossum in the sunflower family. The Latin specific epithet plantagineum refers to the leaves of the plant which are similar to those of a plantain.W. T. Parsons, William Thomas Parsons and E. G. Cuthbertson

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 Arnoglossum plantagineum has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualArnoglossum plantagineum 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.

Where the DNA of Arnoglossum plantagineum 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.
