Epilobium glaberrimum is a species of willowherb known by the common name glaucous willowherb. This clumping perennial wildflower is native to western North America from central Canada to northern Mexico. It generally grows at some elevation in moist places. This plant is somewhat variable in appearance. It may exceed half a meter in height and has hairless foliage with leaves between one and 8 centimeters long. The flower has four notched petals in purple, pink, or white which may be only a couple of millimeters long to over a centimeter long each. The fruit is a narrow, sticklike capsule 2 to 7 centimeters long. Two subspecies are recognized as valid: Epilobium glaberrimum ssp. fastigiatum (Nutt.) Hoch & P.H.Raven Epilobium glaberrimum ssp. glaberrimum

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 Epilobium glaberrimum has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualEpilobium glaberrimum 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 Epilobium glaberrimum 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.
