01Narrative
Stachys albens, also known as whitestem hedgenettle or white hedgenettle, is a mint endemic to California.Calflora: Stachys albens S. albens flowers have a 2-lipped, 5-lobed calyx, which is densely cob-webby and white to pinkish in color with purplish veins.UC/JEPS: Jepson Manual treatment for STACHYS albens The plant is fuzzy all over, with opposite, triangular, serrate leaves, a square stem, a layered spike of many small flowers, and a minty smell if bruised.

Compounds documented for Stachys albens across natural-product and food-composition databases — not just the ~150 nutrients on a classic label ("nutritional dark matter").
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 Stachys albens has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualStachys albens 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.

How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.
