Lupinus nanus, the sky lupine, field lupine, dwarf lupin, ocean-blue lupine or Douglas' annual lupine, is a species of lupine native to the western United States. It is found natively in California, Nevada, and on Steens Mountain in eastern Oregon. It tends to grow on slopes and in open or disturbed areas below 1300 meters. It grows 6 to tall with blue flowers containing white or yellow spots. It is an annual plant that blooms in the months of March, April and May. It contains anagyrine and is considered toxic if directly ingested. Among the biologically active chemicals found in the plant are genistein, 2'-hydroxygenistein, luteone and wighteone.

Compounds documented for Lupinus nanus 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 Lupinus nanus has left across the world's sequence archives.

06Genome at a glanceCCDB
The complete instruction manualLupinus nanus 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.

Where the DNA of Lupinus nanus 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.
